Abstract
Importance Gastric and gastroesophageal junction cancers are diagnosed in more than 1 million people worldwide annually, and few effective treatments are available. Sintilimab, a recombinant human IgG4 monoclonal antibody that binds to programmed cell death 1 (PD-1), in combination with chemotherapy, has demonstrated promising efficacy. Objective To compare overall survival of patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction cancers who were treated with sintilimab with chemotherapy vs placebo with chemotherapy. Also compared were a subset of patients with a PD ligand 1 (PD-L1) combined positive score (CPS) of 5 or more (range, 1-100). Design, Setting, and Participants Randomized, double-blind, placebo-controlled, phase 3 clinical trial conducted at 62 hospitals in China that enrolled 650 patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma between January 3, 2019, and August 5, 2020. Final follow-up occurred on June 20, 2021. Interventions Patients were randomized 1:1 to either sintilimab (n = 327) or placebo (n = 323) combined with capecitabine and oxaliplatin (the XELOX regimen) every 3 weeks for a maximum of 6 cycles. Maintenance therapy with sintilimab or placebo plus capecitabine continued for up to 2 years. Main Outcomes and Measures The primary end point was overall survival time from randomization. Results Of the 650 patients (mean age, 59 years; 483 [74.3%] men), 327 were randomized to sintilimab plus chemotherapy and 323 to placebo plus chemotherapy. Among the randomized patients, 397 (61.1%) had tumors with a PD-L1 CPS of 5 or more; 563 (86.6%) discontinued study treatment and 388 (59.7%) died; 1 patient (<0.1%) was lost to follow-up. Among all randomized patients, sintilimab improved overall survival compared with placebo (median, 15.2 vs 12.3 months; stratified hazard ratio [HR], 0.77 [95% CI, 0.63-0.94]; P = .009). Among patients with a CPS of 5 or more, sintilimab improved overall survival compared with placebo (median, 18.4 vs 12.9 months; HR, 0.66 [95% CI, 0.50-0.86]; P = .002). The most common grade 3 or higher treatment-related adverse events were decreased platelet count (sintilimab, 24.7% vs placebo, 21.3%), decreased neutrophil count (sintilimab, 20.1% vs placebo, 18.8%), and anemia (sintilimab, 12.5% vs placebo, 8.8%). Conclusions and Relevance Among patients with unresectable locally advanced or metastatic gastric and gastroesophageal junction adenocarcinoma treated with first-line chemotherapy, sintilimab significantly improved overall survival for all patients and for patients with a CPS of 5 or more compared with placebo.

Abstract
IMPORTANCE Cotargeting vascular endothelial growth factor and programmed cell death 1 or programmed cell death ligand 1 may produce anticancer activity in refractory metastatic colorectal cancer (mCRC). The clinical benefit of atezolizumab combined with chemotherapy and bevacizumab remains unclear for the treatment of mCRC. OBJECTIVES To assess whether the addition of atezolizumab to capecitabine and bevacizumab therapy improves progression-free survival (PFS) among patients with refractory mCRC and to perform exploratory analyses among patients with microsatellite-stable (MSS) disease and liver metastasis. DESIGN, SETTING, AND PARTICIPANTS This double-blind phase 2 randomized clinical trial enrolled 133 patients between September 25, 2017, and June 28, 2018 (median duration of follow-up for PFS, 20.9 months), with data cutoff on May 4, 2020. The study was conducted at multiple centers through the Academic and Community Cancer Research United network. Adult patients with mCRC who experienced disease progression while receiving fluoropyrimidine, oxaliplatin, irinotecan, bevacizumab, and anti-epidermal growth factor receptor antibody therapy (if the patient had a RAS wild-type tumor) were included. INTERVENTIONS Patients were randomized (2:1) to receive capecitabine (850 or 1000 mg/m2) twice daily on days 1 to 14 and bevacizumab (7.5 mg/kg) on day 1 plus either atezolizumab (1200 mg; investigational group) or placebo (placebo group) on day 1 of each 21-day cycle. MAIN OUTCOMES AND MEASURES The primary end point was PFS; 110 events were required to detect a hazard ratio (HR) of 0.65 with 80% power (1-sided α = .10). Secondary end points were objective response rate, overall survival (OS), and toxic effects. RESULTS Of 133 randomized patients, 128 individuals (median age, 58.0 years [IQR, 51.0-65.0 years]; 77 men [60.2%]) were assessed for efficacy (82 in the investigational group and 46 in the placebo group). Overall, 15 patients (11.7%) self-identified as African American or Black, 8 (6.3%) as Asian, 1 (0.8%) as Pacific Islander, 101 (78.9%) as White, 1 (0.8%) as multiple races (Asian, Native Hawaiian/Pacific Islander, and White), and 2 (1.6%) as unknown race or unsure of race. Microsatellite-stable disease was present in 110 patients (69 in the investigational group and 41 in the placebo group). Median PFS was 4.4 months (95% CI, 4.1-6.4 months) in the investigational group and 3.6 months (95% CI, 2.2-6.2 months) in the placebo group (1-sided log-rank P = .07, a statistically significant result; HR, 0.75; 95% CI, 0.52-1.09). Among patients with MSS and proficient mismatch repair, the HR for PFS was 0.66 (95% CI, 0.44-0.99). The most common grade 3 or higher treatment-related adverse events in the investigational vs placebo groups were hypertension (6 patients [7.0%] vs 2 patients [4.3%]), diarrhea (6 patients [7.0%] vs 2 patients [4.3%]), and hand-foot syndrome (6 patients [7.0%] vs 2 patients [4.3%]). One treatment-related death occurred in the investigational group. In the investigational group, the response rate was higher among patients without liver metastasis (3 of 13 individuals [23.1%]) vs with liver metastasis (4 of 69 individuals [5.8%]). The benefit of atezolizumab for PFS and OS was greater among patients without vs with liver metastasis (primary analysis of PFS: HR, 0.63 [95% CI, 0.27-1.47] vs 0.77 [95% CI, 0.51-1.17]; OS: HR, 0.33 [95% CI, 0.11-1.02] vs 1.14 [95% CI, 0.72-1.81]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, the addition of atezolizumab to capecitabine and bevacizumab therapy provided limited (ie, not clinically meaningful) clinical benefit. Patients with MSS and proficient mismatch repair tumors and those without liver metastasis benefited more from dual inhibition of the vascular endothelial growth factor and programmed cell death 1 or programmed cell death ligand 1 pathways.

Abstract
To evaluate the efficacy and safety of bevacizumab combined with chemotherapy in the treatment of advanced colorectal cancer and the effect on its adverse reactions, 100 patients with advanced colorectal cancer admitted to our hospital from March 2019 to March 2021 were identified as study subjects and were randomly divided into a control group and an experimental group, with 50 cases in each group. The control group was treated with chemotherapy, and the experimental group was given a combination of bevacizumab with chemotherapy. The treatment efficacy, safety, and incidence of adverse reactions in both groups were analyzed and compared. The effectiveness and disease control rate of the experimental group were 50% and 96%, which were significantly higher than those of 26% and 80% in the control group (P<0.05). After treatment, the experimental group exhibited a significantly lower serum vascular endothelial growth factor level and heat shock protein 90α (HSP90α) level compared with that of the control group (P<0.05). Markedly higher apoptosis index of tumor cells was observed in the experimental group than in the control group (P<0.05). The incidence of adverse reactions was 8% in the experimental group, which was significantly lower than that of 28% in the control group (P<0.05). The post-treatment quality of life scores in the experimental group exceeded that in the control group (P<0.05). Bevacizumab combined with chemotherapy for advanced colorectal cancer boosts treatment efficiency, promotes apoptosis of tumor cells, down regulates HSP90α level and enhances patients' quality of life with high safety, which is worthy of clinical promotion and application.

Abstract
INTRODUCTION In rectal cancer, neoadjuvant chemoradiation (NCRT) is preferred because of toxicity profile, improved resectability and sphincter preservation, although with no impact on overall survival. Pathologic complete response (pCR) to NCRT has been linked with longer disease-free survival (DFS). The study purpose was to evaluate an association between clinical factors and treatment schedule with tumor response and treatment outcome, among patients with locally advanced rectal cancer. PATIENTS AND METHODS In this single-center retrospective study, conducted over 9 years (2011 to 2020), patients with stage II to III rectal cancer who had received NCRT were enrolled. The standard radiotherapy was 45 Gy to the pelvis, with a simultaneous integrated 50 Gy boost to the primary tumor. Continuous 5-Fluorouracil or oral capecitabine was administered concurrently. Surgery was preplanned within 6 to 8 weeks. Multinomial logistic regressions for evaluation of clinical factors, Kaplan-Meier method for DFS estimation, and receiver operating characteristic analysis for determination of the optimal timeframe were used. RESULTS Of 279 cases, pCR was observed in 72 (25.8%). In 207 cases, pTis-4N-negative was obtained in 137 (66.2%), pT0N-positive in 6 (2.9%), and pTis-4N-positive in 64 (30.9%). The pCR group had shorter diagnosis-NCRT time (P<0.01) and on-treatment time (P=0.05). DFS was longer for pCR and partial responders with clinical stage II and III (P<0.0001). Diagnosis-NCRT time was shown different between pCR and non-pCR groups. receiver operating characteristic analysis (P<0.01) showed that a diagnosis-NCRT time of <4.5 weeks predicts pCR with a sensitivity of 88% and specificity of 81% accuracy. CONCLUSION The time elapsed between rectal cancer diagnosis and NCRT initiation is significantly associated with pCR. Reducing this time may increase the probability of achieving pCR.

Abstract
The administration of approved systemic treatments for advanced hepatocellular carcinoma (HCC) is limited to patients with preserved liver function (Child-Pugh A/B7) and performance status. Conversely, metronomic chemotherapy can be safely administered to patients with poor clinical conditions and severe liver impairment. The metronomic schedule demonstrated to exert different anticancer mechanisms compared to that of the same agent administered at its standard schedule, including immune stimulation and the inhibition of angiogenesis and vasculogenesis. Nevertheless, metronomic chemotherapy is a nearly neglected option for the treatment of advanced HCC patients, even among those who cannot afford standard treatments. Herein, we report the case of a 40-year-old patient affected by HBV-HDV-related cirrhosis who was diagnosed with advanced HCC. The severe liver impairment (Child-Pugh B9) did not allow to administer first-line treatment with tyrosine kinase inhibitors so that the patient received metronomic capecitabine as upfront therapy. Due to the suspect of progressive disease at the first radiologic assessment, metronomic cyclophosphamide was added to capecitabine aiming to enhance its efficacy. After 4 months of treatment, complete tumor response, alpha-fetoprotein (AFP) normalization and the recovery of a Child-Pugh A were achieved. The patient was then able to undergo liver transplantation, and, after 18 months from the diagnosis, he is still free of disease recurrence. This experience emphasizes the reliability of metronomic capecitabine as a well-tolerated and effective treatment when patient's conditions prevent the administration of standard first-line treatments. In fact, metronomic capecitabine demonstrated its effectiveness in advanced HCC in retrospective and prospective analyses, leading to median progression-free survival and overall survival of, respectively, 6.03 and 14.47 months in phase II single-arm trial. Moreover, in consideration of the raising interest in immune-checkpoint inhibition in HCC, we believe that the immunomodulating effects of metronomic chemotherapy, either capecitabine or cyclophosphamide, warrant future trials exploring its combination with immunotherapy.

Abstract
PURPOSE Neratinib plus capecitabine (N+C) demonstrated significant progression-free survival (PFS) benefit in NALA (NCT01808573), a randomized phase III trial comparing N+C with lapatinib + capecitabine (L+C) in 621 patients with HER2-positive (HER2+) metastatic breast cancer (MBC) who had received ≥2 prior HER2-directed regimens in the metastatic setting. We evaluated correlations between exploratory biomarkers and PFS. PATIENTS AND METHODS Somatic mutations were evaluated by next-generation sequencing on primary or metastatic samples. HER2 protein expression was evaluated by central IHC, H-score, and VeraTag/HERmark. p95 expression (truncated HER2) was measured by VeraTag. HRs were estimated using unstratified Cox proportional hazards models. RESULTS Four hundred and twenty samples had successful sequencing: 34.0% had PIK3CA mutations and 5.5% had HER2 (ERBB2) mutations. In the combined patient populations, PIK3CA mutations trended toward shorter PFS [wild-type vs. mutant, HR = 0.81; 95% confidence interval (CI), 0.64-1.03], whereas HER2 mutations trended toward longer PFS [HR = 1.69 (95% CI, 0.97-3.29)]. Higher HER2 protein expression was associated with longer PFS [IHC 3+ vs. 2+, HR = 0.67 (0.54-0.82); H-score ≥240 versus <240, HR = 0.77 (0.63-0.93); HERmark positive vs. negative, HR = 0.76 (0.59-0.98)]. Patients whose tumors had higher HER2 protein expression (any method) derived an increased benefit from N+C compared with L+C [IHC 3+, HR = 0.64 (0.51-0.81); H-score ≥ 240, HR = 0.54 (0.41-0.72); HERmark positive, HR = 0.65 (0.50-0.84)], as did patients with high p95 [p95 ≥2.8 relative fluorescence (RF)/mm2, HR = 0.66 (0.50-0.86) vs. p95 < 2.8 RF/mm2, HR = 0.91 (0.61-1.36)]. CONCLUSIONS PIK3CA mutations were associated with shorter PFS whereas higher HER2 expression was associated with longer PFS. Higher HER2 protein expression was also associated with a greater benefit for N+C compared with L+C.

Abstract
RATIONALE Colorectal mixed neuroendocrine-nonneuroendocrine neoplasms constitute a rare group of gastrointestinal tumors composed by both neuroendocrine and nonneuroendocrine components. Nondiagnostic macroscopic features, specific histological features, and poor awareness of the disease are responsible for the underestimated incidence and conflicting data available. Due to lack of randomized clinical trials and validated clinical guidelines, diagnostic and therapeutic approach are based on the standard of care for pure colorectal neuroendocrine carcinomas or adenocarcinomas. PATIENT CONCERNS A 76-year-old caucasian male, without relevant medical or familial history, presented a positive faecal occult blood test during colorectal cancer screening. DIAGNOSIS Total colonoscopy identified a rectal lesion with biopsy showing a moderate rectal adenocarcinoma staged as cT2N0M0. INTERVENTIONS Anterior resection of the rectum with right ileostomy followed by local radiotherapy with radio-sensitising chemotherapy and adjuvant chemotherapy with capecitabine 1000 mg bid plus oxaliplatin 130 mg/m2. Due to chronic nodular pulmonary aspergillosis and chemotherapy induced immunosuppression patient was on 400 mg/daily of oral voriconazole. OUTCOMES Overall survival of 15 months after progression under first line treatment and under palliative chemotherapy with platinum plus etoposide regimen. LESSONS The reported case illustrates the challenge associated to the management of mixed neuroendocrine-nonneuroendocrine carcinomas due to lack of validated guidelines and scientific evidence. From diagnosis and staging to treatment, all steps must be tailored to individual clinical and histological features.

Abstract
PURPOSE We evaluated study outcomes in patients enrolled in Asian regions in the phase III EMBRACA trial of talazoparib vs. chemotherapy. MATERIALS AND METHODS Patients with human epidermal growth factor receptor 2-negative germline BRCA1/2-mutated advanced breast cancer who received prior chemotherapy were randomized 2:1 to talazoparib 1 mg/day or chemotherapy (physician's choice). Primary endpoint was progression-free survival (PFS) per independent central review in the intent-to-treat (ITT) population. This post-hoc analysis evaluated efficacy/safety endpoints in the ITT population of patients enrolled in Asian regions. RESULTS Thirty-three patients were enrolled at Asian sites (talazoparib, n=23; chemotherapy, n=10). Baseline characteristics were generally comparable with the overall EMBRACA population. In Asian patients, median PFS was 9.0 months (95% confidence interval [CI], 3.0 to 15.2) for talazoparib and 7.1 months (95% CI, 1.2 to not reached) for chemotherapy (hazard ratio [HR], 0.74 [95% CI, 0.22 to 2.44]). Objective response rate was numerically higher for talazoparib vs. chemotherapy (62.5% [95% CI, 35.4 to 84.8] vs. 25.0% [95% CI, 3.2 to 65.1]). Median overall survival was 20.7 months (95% CI, 9.4 to 40.1) versus 21.2 months (95% CI, 2.7 to 35.0) (HR, 1.41 [95% CI, 0.49 to 4.05]). In Asian patients, fewer grade 3/4 adverse events (AEs), serious AEs (SAEs), grade 3/4 SAEs, and AEs resulting in dose reduction/discontinuation occurred with talazoparib than chemotherapy; for talazoparib, the frequency of these events was lower in Asian patients versus overall EMBRACA population. CONCLUSION In this subgroup analysis, talazoparib numerically improved efficacy versus chemotherapy and was generally well tolerated in Asian patients, with fewer grade 3/4 treatment-emergent AE (TEAEs), SAEs, and TEAEs leading to dose modification vs. the overall EMBRACA population.

Abstract
New classes of antibiotics are needed to fight bacterial infections, and repurposing existing drugs as antibiotics may enable rapid deployment of new treatments. Screens for antibacterials have been traditionally performed in standard laboratory media, but bacterial pathogens experience very different environmental conditions during infection, including nutrient limitation. To introduce the next generation of researchers to modern drug discovery methods, we developed a course-based undergraduate research experience (CURE) in which undergraduate students screened a library of FDA-approved drugs for their ability, in a nutrient-poor medium, to prevent the growth of the human Gram-negative bacterial pathogen Salmonella enterica serovar Typhimurium. The nine drugs identified all disrupt DNA metabolism in bacteria and eukaryotes. One of the hit compounds, capecitabine, is a well-tolerated oncology drug that is administered orally, a preferred treatment route. We demonstrated that capecitabine is more effective at inhibiting S. Typhimurium growth in nutrient-limited than in standard rich microbiological broth, an explanation for why the antibiotic activity of this compound has not been previously recognized. Capecitabine is enzymatically converted to the active pyrimidine analogue, fluorouracil (5-FU), and Gram-positive bacteria, including Staphylococcus aureus, are significantly more sensitive to 5-FU than Gram-negative bacteria. We therefore tested capecitabine for efficacy in a murine model of S. aureus peritonitis. Oral capecitabine administration reduced the colonization of tissues and increased animal survival in a dose-responsive manner. Since capecitabine is inexpensive, orally available, and relatively safe, it may have utility for treatment of intractable Gram-positive bacterial infections. IMPORTANCE As bacterial infections become increasingly insensitive to antibiotics, whether established, off-patent drugs could treat infections becomes an important question. At the same time, basic research has revealed that during infection, mammals starve pathogens for nutrients and, in response, bacteria dramatically alter their biology. Therefore, it may be fruitful to search for drugs that could be repurposed as antibiotics using bacteria grown with limited nutrients. This approach, executed with undergraduate student researchers, identified nine drugs known to interfere with the production and/or function of DNA. We further explored one of these drugs, capecitabine, a well-tolerated human oncology drug. Oral administration of capecitabine reduced infection with the human pathogen Staphylococcus aureus and increased survival in mice. These data suggest that capecitabine has potential as a therapy for patients with otherwise untreatable bacterial infections.

Abstract
AIM Capecitabine (Cape) is routinely used for the neoadjuvant chemoradiation treatment (NACRT) of locally advanced rectal cancers (LARCs). Previous reports have suggested that the concomitant use of proton pump inhibitors (PPIs) may affect the efficacy of Cape, although the true effect of PPIs when used with Cape as a radiosensitizer for neoadjuvant radiation is unclear. The aim of our study was to evaluate the impact of concurrent PPI use along with fluorouracil (FU) and Cape based NACRT in terms of pathologic and oncological outcomes, in patients with LARC. METHODS LARC patients treated at our center with NACRT from 2010 to 2016 were identified. Postoperative pathology and follow-up outcomes were examined for any differences with relation to the use of PPIs concurrently with FU and Cape based NACRT and adjuvant chemotherapy regimens. RESULTS Three hundred four and 204 patients received treatment with FU and Cape based NACRT. No difference in pathologic complete response rate was noted between the 2 arms with the concurrent use of PPIs (25.8% and 25%, respectively, P=0.633); or with and without the use of PPIs in the Cape-NACRT arm specifically (20% and 20.7%, P=0.945). At a median follow-up of 5 years, no statistical difference in local or distant control was noted in the Cape-NACRT patients, with and without concomitant PPI use (P=0.411 and 0.264, respectively).Multivariate analysis showed no association of PPI use and NACRT with Cape, in terms of local control (hazard ratio=0.001, P=0.988) or overall survival (hazard ratio=1.179, confidence interval=0.249-5.579, P=0.835). CONCLUSIONS Our study revealed that there was no adverse pathologic or oncological outcome with the concurrent use of PPIs along with Cape-NACRT in the treatment of LARC. We report that it may be safe to use PPIs if essential, in this clinical setting, although it would be wise to exercise caution.

Abstract
OBJECTIVES The standard of care for resectable gastric cancers (GCs) includes perioperative chemotherapy (CT) or postoperative chemo/chemoradiotherapy (CRT) strategies. Poor treatment compliance postsurgery suggests that intensified surgical adjuvant treatment is more likely deliverable preceding surgery and, therefore, the safety and efficacy of perioperative cisplatin-capecitabine (CX) with preoperative chemoradiation (preopCRT) were ascertained. MATERIALS AND METHODS Between January 2017 and December 2018, 28 potentially resectable locally advanced GC patients were offered neoadjuvant CT-2 cycles of CX at 3-weekly intervals, followed by preopCRT 45 Gy/25 fractions/5 weeks and concurrent capecitabine, followed by surgical resection and 3 adjuvant cycles of CX. RESULTS Neoadjuvant CT was commenced in 28 patients (100%), preopCRT in 18 patients (64%), and surgery performed in 13 patients (46%). At each treatment step, decreasing patient numbers were due mainly to disease progression (12 [43%]) or other reasons, including (3 [11%]) from treatment-related toxicity. The R0 resection rate was 92% (12/13); a median of 18 nodes was obtained after D2 nodal clearance in 92% (12/13). There were 20%/4%/4% grade 3/4/5 toxicities. The median radiotherapy dose/duration was 45 Gy/5.4 weeks. Adjuvant CT was started in 11 patients (39%) and the third cycle was received by 7 patients (25%). No tumor (ypT0N0) was noted in 23% of the operated patients (3/13), or 11% of the intention-to-treat population (3/28). The median, 1-year, and 2-year survivals were 12 months, 53%, and 32%, respectively. CONCLUSIONS Intensified preoperative treatment is doable in relatively unselected advanced GC patients in real-world settings of a public-sector hospital from a low-middle-income country. Disease progression during preoperative therapy allows patients destined for early clinical evidence of disease dissemination to avoid futile surgery, as opposed to a surgery-first strategy, without an overt increase in surgical morbidity or mortality, with encouraging R0 resection rates.

Abstract
Corticotroph carcinomas and aggressive corticotroph tumors can be resistant to conventional therapy, including surgery, radiotherapy, and medical treatment. Recent evidence suggests that temozolomide (an oral alkylating agent) administered with capecitabine (pro-drug of 5-fluorouracil) may improve progression-free survival in patients with high-risk corticotroph tumors and carcinomas. This led to the use of capecitabine and temozolomide (CAPTEM) in two patients, one with a corticotroph carcinoma and the other with an aggressive corticotroph tumor, as well the in vitro analysis of capecitabine and 5-fluorouracil on cell growth and hormone production. Both patients had previous surgical and radiation therapy. The first patient developed leptomeningeal spread 2 years after his radiation treatment. He had 12 cycles of CAPTEM, which resulted in tumor control associated with clinical and radiological improvement. Twenty-seven months later, CAPTEM was restarted for disease recurrence with ongoing tumor response. The second patient had a rapid tumor regrowth 2 years after his third surgical resection. He was treated with 12 cycles of CAPTEM, which led to tumor shrinkage with no tumor regrowth 22 months after cessation of therapy. Experiments using mouse ACTH-producing pituitary tumor AtT20 cells demonstrated that treatment with 5-fluorouracil in combination with temozolomide had an additive effect in reducing cell viability and ACTH production in the culture medium. Our patients and experimental data in AtT20 cells support CAPTEM as a potential treatment option for aggressive corticotroph tumors and carcinomas. However, a prospective clinical trial is required to determine whether CAPTEM is superior to temozolomide in the treatment of these tumors.

Abstract
PURPOSE Neoadjuvant chemoradiation followed by surgery is the current standard of care in the treatment of locally advanced rectal cancer. Those who achieved pathologic complete response, following this standard of care, complete pathologic response (pCR) had better outcome. Until now there are no reliable clinical parameters to predict this response. The purpose of the study was to evaluate whether tumor volume may serve as a predictive factor in patients treated with neoadjuvant chemoradiotherapy. MATERIALS AND METHODS Between September 2015 and September 2019, patients diagnosed with stage IIA to IIIC rectal adenocarcinoma, who were treated with neoadjuvant chemoradiation, were enrolled to this study. All patients underwent rectal ultrasound, pelvic magnetic resonance imaging, fluorodeoxyglucose-positron emission tomography-computed tomography and the diagnosis was confirmed by pathology report. Radiation therapy was consisted of 50 Gy delivered to the tumor site, 2 Gy a day, 5 times a week and to the pelvic lymph nodes for a total of 45 Gy in 1.8 Gy a day, 5 times a week. The gross tumor volume (GTV) was contoured by radiation oncology expert, reviewed by radiology and nuclear medicine expert and approved by radiation therapy tumor board. Chemotherapy was consisted of either capecitabine 875 mg/m2 twice a day or continuous. IV infusion of 5 fluorouracil 375 mg/m2 for 4 consecutive days in a 3 weeks apart. Operation, either low anterior or abdominoperineal resection was carried out 6 to 8 weeks following completion of treatment. Patients were assigned to either complete pathologic response (pCR) or non-pCR groups. GTV, among other clinical and treatment parameters, were evaluated for prediction of pCR. Statistical methods included independent t test, logistic regression, area under the curve-receiver operating characteristic, Bayesian independent statistics and multilayer perceptron model. RESULTS One hundred ninety-three patients were enrolled to this study, 6 were excluded due to metastatic disease detected at the time of operation. Seventy had stage II and 117 had stage III. Forty-four of 187 (23.5%) patients achieved pCR and 143 patients had either partial or no response/progressive disease. Among the 44 pCR group, 21 had stage II and 23 had stage III disease. Treatment interruption, defined as either a delay of up to 1 week in radiation, and a dose reduction to 75%, was occurred in 42 patients. Sex, ethnicity, distance from anal verge to tumor, height, weight, age, delivered radiation dose, radiotherapy techniques, clinical T and N stage and GTV were evaluated for prediction of pCR. GTV at the volume of <39.5 cm3 was the only significant predictive factor to detect pCR by logistic regression model (P<0.01) and by Bayesian independent test (P=0.026). Area under the receiver operating characteristic curve of GTV <39.5 cm3 showed area under the curve of 0.715 (P=0.009) for stage II and area under the curve of 0.62 (P>0.05) for stage III. CONCLUSION GTV may serve as a predictive factor for achieving pCR in locally advanced rectal cancer after neoadjuvant chemoradiotherapy.

Abstract
OPINION STATEMENT Gastric and gastroesophageal junction (GEJ) cancers represent the third leading cause of malignancy-associated death worldwide. Approximately 15-20% of these adenocarcinomas overexpress the human epidermal growth factor receptor 2 (HER2), a pro-proliferative receptor tyrosine kinase that has been therapeutically exploited in other disease contexts. The landmark ToGA trial demonstrated that trastuzumab, an anti-HER2 antibody, could improve overall survival for patients with HER2 overexpressing advanced gastric and GEJ adenocarcinomas. In the ensuing decade, great effort has been made to refine and expand this therapeutic strategy through a variety of avenues including optimization of chemotherapy backbones, identifying potential synergy with immune checkpoint inhibition, deployment of alternative HER2-targeted antibodies, use of small molecule inhibitors, and development of HER2-directed antibody drug conjugates. While the results of these efforts have had variable success, they have led to a greater understanding of the mechanisms of both primary and acquired resistance to HER2-directed therapies, laying the groundwork for future investigations. Recently, KEYNOTE-811 and DESTINY-Gastric01 have led to the FDA approvals of pembrolizumab in combination with trastuzumab and chemotherapy in the 1st-line advanced setting and trastuzumab deruxtecan (fam-trastuzumab deruxtecan-nxki) in the 2nd-line setting, respectively. Herein, we review these significant works as well as discuss the ongoing investigations they have inspired, which aim to find and utilize additional means for targeting HER2 in gastric and GEJ cancers.

Abstract
Background Traditionally, adjuvant treatment for colon cancer has been 6 months of combination chemotherapy. Six phase III trials tested the hypothesis that 3 months is noninferior in efficacy to 6 months and reduces long-term side effects for patients. The results were pooled in the International Duration Evaluation of Adjuvant therapy (IDEA) collaboration. Although this did not meet the noninferiority endpoint, a preplanned subgroup analysis by chemotherapy regimen did demonstrate noninferiority for capecitabine and oxaliplatin. Additionally, risk stratification by T and N stage was defined. Methods In an effort to understand the real-life impact of these results, 4 months after the IDEA results, an online survey was distributed to clinicians to ask their approach to the adjuvant treatment of patients with stage III colon cancer. Results The survey was completed by 458 clinicians from 12 countries. Assuming that 6 months of treatment was the pretrial standard of care, 89.5% of clinicians reported they had changed practice to prescribe 3 months of treatment for some patients. For patients with low-risk stage III disease, there was a preference for 3 months, and for patients with high-risk stage III disease, most clinicians still prescribed 6 months at that time. Overall, capecitabine and oxaliplatin regimen was the most popular. There were important differences in responses depending on the location of respondent and T and N stage of disease. Conclusion This survey shows that the IDEA collaboration has been practice changing but reveals important differences in the way results are interpreted by individual clinicians.

BACKGROUND Patients with locoregionally advanced nasopharyngeal carcinoma have a high risk of disease relapse, despite a high proportion of patients attaining complete clinical remission after receiving standard-of-care treatment (ie, definitive concurrent chemoradiotherapy with or without induction chemotherapy). Additional adjuvant therapies are needed to further reduce the risk of recurrence and death. However, the benefit of adjuvant chemotherapy for nasopharyngeal carcinoma remains controversial, highlighting the need for more effective adjuvant treatment options. METHODS This multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial was done at 14 hospitals in China. Patients (aged 18-65 years) with histologically confirmed, high-risk locoregionally advanced nasopharyngeal carcinoma (stage III-IVA, excluding T3-4N0 and T3N1 disease), no locoregional disease or distant metastasis after definitive chemoradiotherapy, an Eastern Cooperative Oncology Group performance status of 0 or 1, sufficient haematological, renal, and hepatic function, and who had received their final radiotherapy dose 12-16 weeks before randomisation, were randomly assigned (1:1) to receive either oral metronomic capecitabine (650 mg/m2 body surface area twice daily for 1 year; metronomic capecitabine group) or observation (standard therapy group). Randomisation was done with a computer-generated sequence (block size of four), stratified by trial centre and receipt of induction chemotherapy (yes or no). The primary endpoint was failure-free survival, defined as the time from randomisation to disease recurrence (distant metastasis or locoregional recurrence) or death due to any cause, in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of capecitabine or who had commenced observation. This trial is registered with ClinicalTrials.gov, NCT02958111. FINDINGS Between Jan 25, 2017, and Oct 25, 2018, 675 patients were screened, of whom 406 were enrolled and randomly assigned to the metronomic capecitabine group (n=204) or to the standard therapy group (n=202). After a median follow-up of 38 months (IQR 33-42), there were 29 (14%) events of recurrence or death in the metronomic capecitabine group and 53 (26%) events of recurrence or death in the standard therapy group. Failure-free survival at 3 years was significantly higher in the metronomic capecitabine group (85·3% [95% CI 80·4-90·6]) than in the standard therapy group (75·7% [69·9-81·9]), with a stratified hazard ratio of 0·50 (95% CI 0·32-0·79; p=0·0023). Grade 3 adverse events were reported in 35 (17%) of 201 patients in the metronomic capecitabine group and in 11 (6%) of 200 patients in the standard therapy group; hand-foot syndrome was the most common adverse event related to capecitabine (18 [9%] patients had grade 3 hand-foot syndrome). One (<1%) patient in the metronomic capecitabine group had grade 4 neutropenia. No treatment-related deaths were reported in either group. INTERPRETATION The addition of metronomic adjuvant capecitabine to chemoradiotherapy significantly improved failure-free survival in patients with high-risk locoregionally advanced nasopharyngeal carcinoma, with a manageable safety profile. These results support a potential role for metronomic chemotherapy as an adjuvant therapy in the treatment of nasopharyngeal carcinoma.

Abstract
PURPOSE The purpose of this study was to investigate the efficacy and safety of maintenance therapy of capecitabine metronomic chemotherapy combined with autologous cytokine-induced killer (CIK) cell immunotherapy in patients with recurrent metastatic triple-negative breast cancer (mTNBC). METHODS The clinical data of 110 patients with recurrent mTNBC were retrospectively analyzed. Among, 55 were treated with maintenance therapy of capecitabine metronomic chemotherapy combined with autologous CIK cell immunotherapy (DC-CIK group), while the rest 55 were treated with simple metronomic chemotherapy (control group). RESULTS The ORR of patients in DC-CIK group and control group was 29.1% and 16.4%, and the DCR was 74.5% and 63.6%, respectively. After treatment, the proportions of CD3+ T lymphocytes, CD4+ T lymphocytes and NK cells as well as the CD4/CD8 cell ratio were notably higher in DC-CIK group than those in control group, while the proportion of CD8+ T lymphocytes was notably lower in DC-CIK group than that in control group. Compared with those before treatment, the scores of quality of life evaluated using the FACT-B-V4.0 scale were remarkably improved in both groups after treatment. The score of emotional status and total score were distinctly higher in DC-CIK group than those in control group. Moreover, the follow-up results together with log-rank test revealed that the PFS in DC-CIK group was notably superior to that in control group. CONCLUSIONS The maintenance therapy of capecitabine metronomic chemotherapy combined with DC-CIK cell immunotherapy is effective in the treatment of recurrent mTNBC, with tolerable adverse reactions. It can improve the patients' immune function, improve their quality of life, and prolong their PFS. Key words: capecitabine, metronomic chemotherapy, immunotherapy, breast cancer, recurrent and metastatic.

Abstract
Glycosylated pH-sensitive mesoporous silica nanoparticles (MSNs) of capecitabine (CAP) were developed for targeting colorectal cancer. The MSNs possessed an average pore diameter of 8.12 ± 0.43 nm, pore volume of 0.73 ± 0.21 cm3/g, and particle size of 245.24 ± 5.75 nm. A high loading of 180.51 ± 5.23 mg/g attributed to the larger pore volume was observed. The surface of the drug-loaded MSNs were capped with chitosan-glucuronic acid (CHS-GCA) conjugate to combine two strategies viz. pH-sensitive, and lectin receptor mediated uptake. In vitro studies demonstrated a pH-sensitive and controlled release of CAP which was further enhanced in the presence of rat caecal content. Higher uptake of the (CAP-MSN)CHS-GCA was observed in HCT 116 cell lines. The glycosylated nanoparticles revealed reduction in the tumors, aberrant crypt foci, dysplasia and inflammation, and alleviation in the toxic features. This illustrated that the nanoparticles showed promising antitumor efficacy with reduced toxicity and may be used as a effective carrier against cancer.

Abstract
BACKGROUND The Glasgow Microenvironment Score (GMS) combines peritumoural inflammation and tumour stroma percentage to assess interactions between tumour and microenvironment. This was previously demonstrated to associate with colorectal cancer (CRC) prognosis, and now requires validation and assessment of interactions with adjuvant therapy. METHODS Two cohorts were utilised; 862 TNM I-III CRC validation cohort, and 2912 TNM II-III CRC adjuvant chemotherapy cohort (TransSCOT). Primary endpoints were disease-free survival (DFS) and relapse-free survival (RFS). Exploratory endpoint was adjuvant chemotherapy interaction. RESULTS GMS independently associated with DFS (p = 0.001) and RFS (p < 0.001). GMS significantly stratified RFS for both low risk (GMS 0 v GMS 2: HR 3.24 95% CI 1.85-5.68, p < 0.001) and high-risk disease (GMS 0 v GMS 2: HR 2.18 95% CI 1.39-3.41, p = 0.001). In TransSCOT, chemotherapy type (pinteraction = 0.013), but not duration (p = 0.64) was dependent on GMS. Furthermore, GMS 0 significantly associated with improved DFS in patients receiving FOLFOX compared with CAPOX (HR 2.23 95% CI 1.19-4.16, p = 0.012). CONCLUSIONS This study validates the GMS as a prognostic tool for patients with stage I-III colorectal cancer, independent of TNM, with the ability to stratify both low- and high-risk disease. Furthermore, GMS 0 could be employed to identify a subset of patients that benefit from FOLFOX over CAPOX.

Abstract
Background SCOT was an international, randomized phase 3 trial of 3 months vs 6 months of adjuvant chemotherapy with oxaliplatin and a fluoropyrimidine in patients with colorectal cancer. We sought patients' preferences for 3 months vs 6 months of adjuvant chemotherapy in the SCOT trial. Methods SCOT participants from Australia and New Zealand completed a validated questionnaire (at 3 and 18 months) to elicit the minimum survival benefits judged necessary to make an extra 3 months of adjuvant chemotherapy worthwhile, based on their experience. Standardized hypothetical scenarios used the following baseline survivals (with 3 months of chemotherapy): life expectancies (LE) of 5 years and 15 years and 5-year survival rates (5YS) of 65% and 85%. Results Of the 160 participants, 82 were assigned 3 months adjuvant chemotherapy, and 78 were assigned 6 months. Adjuvant chemotherapy was FOLFOX in 121 (75.6%) and XELOX in 39 (24.4%). Preferences varied substantially and did not differ according to treatment group. The median survival benefits judged necessary to make the extra 3 months of chemotherapy worthwhile were an extra 3 years beyond a LE of 5 years; 3 years beyond a LE of 15 years; 15% beyond a 5YS of 65%; and 5% beyond a 5YS of 85%. Preferences were similar at 3 months and 18 months. Preferences were not predicted by participants' baseline characteristics. Conclusion Preferences varied substantially, and the benefits many required to warrant an extra 3 months of adjuvant chemotherapy were larger than the benefits of an extra 3 months of chemotherapy calculated in the International Duration Evaluation of Adjuvant Chemotherapy (IDEA) meta-analysis.

Abstract
IMPORTANCE Among all subtypes of breast cancer, triple-negative breast cancer has a relatively high relapse rate and poor outcome after standard treatment. Effective strategies to reduce the risk of relapse and death are needed. OBJECTIVE To evaluate the efficacy and adverse effects of low-dose capecitabine maintenance after standard adjuvant chemotherapy in early-stage triple-negative breast cancer. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted at 13 academic centers and clinical sites in China from April 2010 to December 2016 and final date of follow-up was April 30, 2020. Patients (n = 443) had early-stage triple-negative breast cancer and had completed standard adjuvant chemotherapy. INTERVENTIONS Eligible patients were randomized 1:1 to receive capecitabine (n = 222) at a dose of 650 mg/m2 twice a day by mouth for 1 year without interruption or to observation (n = 221) after completion of standard adjuvant chemotherapy. MAIN OUTCOMES AND MEASURES The primary end point was disease-free survival. Secondary end points included distant disease-free survival, overall survival, locoregional recurrence-free survival, and adverse events. RESULTS Among 443 women who were randomized, 434 were included in the full analysis set (mean [SD] age, 46 [9.9] years; T1/T2 stage, 93.1%; node-negative, 61.8%) (98.0% completed the trial). After a median follow-up of 61 months (interquartile range, 44-82), 94 events were observed, including 38 events (37 recurrences and 32 deaths) in the capecitabine group and 56 events (56 recurrences and 40 deaths) in the observation group. The estimated 5-year disease-free survival was 82.8% in the capecitabine group and 73.0% in the observation group (hazard ratio [HR] for risk of recurrence or death, 0.64 [95% CI, 0.42-0.95]; P = .03). In the capecitabine group vs the observation group, the estimated 5-year distant disease-free survival was 85.8% vs 75.8% (HR for risk of distant metastasis or death, 0.60 [95% CI, 0.38-0.92]; P = .02), the estimated 5-year overall survival was 85.5% vs 81.3% (HR for risk of death, 0.75 [95% CI, 0.47-1.19]; P = .22), and the estimated 5-year locoregional recurrence-free survival was 85.0% vs 80.8% (HR for risk of locoregional recurrence or death, 0.72 [95% CI, 0.46-1.13]; P = .15). The most common capecitabine-related adverse event was hand-foot syndrome (45.2%), with 7.7% of patients experiencing a grade 3 event. CONCLUSIONS AND RELEVANCE Among women with early-stage triple-negative breast cancer who received standard adjuvant treatment, low-dose capecitabine maintenance therapy for 1 year, compared with observation, resulted in significantly improved 5-year disease-free survival.

Abstract
PURPOSE Following neoadjuvant chemotherapy for breast cancer, postoperative systemic therapy, also called post-neoadjuvant treatment, has been established in defined risk settings. We reviewed the evidence for sequencing of postoperative radiation and chemotherapy, with a focus on a capecitabine and trastuzumab emtansine (T-DM1)-based regimen. METHODS A systematic literature search using the PubMed/MEDLINE/Web of Science database was performed. We included prospective and retrospective reports published since 2015 and provided clinical data on toxicity and effectiveness. RESULTS Six studies were included, five of which investigated capecitabine-containing regimens. Of these, four were prospective investigations and one a retrospective matched comparative analysis. One randomized prospective trial was found for T‑DM1 and radiotherapy. In the majority of these reports, radiation-associated toxicities were not specifically addressed. CONCLUSION Regarding oncologic outcome, the influence of sequencing radiation therapy with maintenance capecitabine chemotherapy in the post-neoadjuvant setting is unclear. Synchronous administration of capecitabine is feasible, but reports on possible excess toxicities are partially conflicting. Dose reduction of capecitabine should be considered, especially if normofractionated radiotherapy is used. In terms of tolerance, hypofractionated schedules seem to be superior in terms of toxicity in concurrent settings. T‑DM1 can safely be administered concurrently with radiotherapy.

Abstract
Nelson's syndrome is considered a severe side effect that can occur after a total bilateral adrenalectomy in patients with Cushing's disease. It usually presents with clinical manifestations of an enlarging pituitary tumor including visual and cranial nerve alterations, and if not treated, can cause death through local brain compression or invasion. The first therapeutic option is surgery but in extreme cases of inaccessible or resistant aggressive pituitary tumors; the off-label use of chemotherapy with capecitabine and temozolomide can be considered. However, the use of this treatment is controversial due to adverse events, lack of complete response, and inability to predict results. We present the case of a 48-year-old man diagnosed with Nelson's syndrome with prolonged partial response and significant clinical benefit to treatment with capecitabine and temozolomide.

Abstract
OBJECTIVE As the genetic and molecular profiles of triple negative breast carcinoma (TNBC) are elucidated, multiple therapeutic targets have been produced. TNBC with less than 1% androgen receptor (AR) expression may respond to enzalutamide with greater response association in higher levels. A metronomic dose of capecitabine and docetaxel are effective developed drugs for angiogenic process inhibition. We aimed to demonstrate the treatment outcome of triple-negative breast cancer patients in correlation to their clinicopathological features. MATERIALS AND METHODS A retrospective cohort study of 80 TNBC patients was conducted. The patients underwent proper observation with the reporting of their treatment and follow-up data. Patients with a metastatic disease, neoadjuvant chemotherapy, follow-up drop or data shortage were excluded from the survival analysis. RESULTS The study results revealed a significant association between negative androgen expression and younger age ≤35 years, premenopausal status, higher grade, extracapsular extension, lymphovascular invasion, Ki 67, and CA15-3 (p=0.003, 0.02, < 0.001, 0.001, 0.027, 0.005, 0.009 respectively). The three-year overall survival (OS) in patients who received bicalutamide was better than those patients who received capecitabine or docetaxel but of no significance (p=0.46). The three-year disease free survival (DFS) was significantly better in the bicalutamide arm versus the other two groups (p=0.012). CONCLUSIONS We concluded that extended adjuvant antiandrogen such as bicalutamide and metronomic capecitabine are well tolerated with accepted compliance and affordability compared to docetaxel and are warranted for problem-solving and better DFS and OS in some TNBC patients.

Abstract
BACKGROUND Neuroendocrine neoplasias (NENs) are a rare group of tumors with different prognosis and response to therapy. Their heterogeneity is dependent on the site of origin, morphology, and Ki67. Temozolomide (TEM) appears to be active in metastatic NENs (mNENs) but there is limited evidence about its efficacy in gastrointestinal NENs. We analyzed "real-world" data on the use of TEM alone or in association with capecitabine (CAPTEM) in patients with mNENs. PATIENTS AND METHODS One hundred consecutive patients with advanced NENs treated with TEM or CAPTEM between 2009 and 2019 were included. A pretreatment tumor growth rate (TGR0) was calculated. Overall survival (OS), progression-free survival (PFS), tolerance, objective response rate (ORR), and disease control rate (DCR) were analyzed. A propensity score analysis and inverse probability of treatment weights for Cox regression models were used. RESULTS TEM-based therapy was administered to 95 patients (26.3% CAPTEM and 83.7% TEM) with a median age of 59 years (range 26-85) years. ECOG performance status was 0-2. Carcinoid syndrome was reported in 12 (12.6%) patients. Twenty (21.1%) patients with grade (G) 3 neuroendocrine carcinoma (NEC) and 9 (9.4%) with G3 neuroendocrine tumors (NETs) were included in the analysis. Median PFS of the entire group was 10.4 months (95% confidence interval [CI]: 6.0-11.5). In multivariate analysis, a higher risk of progression was observed for NEC G3 patients (hazard ratio [HR] 2.70, 95% CI: 1.25-5.84) and for a TGR ≥19.55 (HR: 2.53, 95% CI: 1.45-4.40). Median OS was 23.4 months (95% CI: 17.0-29.0) and was similar in both treatment groups (23.9 vs. 20.5 months for TEM and CAPTEM, respectively, p = 0.585). In multivariate analysis, TGR ≥19.55 was associated with a higher risk of death (HR: 2.18, 95% CI: 1.16-4.11) than TGR <19.55, as was NEC G3 (HR: 2.42, 95% CI: 1.04-5.59) with respect to NETs. No differences in terms of mPFS or mOS were seen in relation to the primary site of disease. In the 86 patients evaluable for response, ORR was 44.1% and the DCR was 70.9%. Mild adverse events (grade I-II) included anemia, neutropenia, and headache. Rare cases of G 3 neutropenia and thrombocytopenia were recorded. CONCLUSIONS TEM-based regimens are associated with a high DCR and a relatively tolerable toxicity profile in NENs of pancreatic, intestinal, and lung origin. Further investigation of these specific NETs is warranted in prospective clinical trials.

Abstract
Maintenance treatment after first-line chemotherapy for patients with metastatic colorectal cancer (mCRC) is a priority strategy. However, which medicine is chosen is controversial. This study aimed to determine the efficacy and safety of maintenance treatment with metronomic capecitabine vs observation.In this randomized controlled trial, patients who completed 18 weeks of induction chemotherapy with XELOX and achieved disease control were randomly assigned centrally (1:1) to receive maintenance therapy with metronomic chemotherapy or observation until disease progression. The primary endpoint was progression-free survival from randomization; secondary endpoints included overall survival and safety. Analyses were performed by intention to treat.Between January 1st, 2017 and December 31th 2018, 48 patients were enrolled and randomly assigned to receive maintenance treatment with metronomic capecitabine (n = 25) or only observation (n = 23). The median progression-free survival in the metronomic capecitabine group was 5.66 (95% confidence interval [CI] 5.25-6.07) months vs 3.98 (95%CI 3.71-4.24) months in the observation group (hazard ratio 0.11, 95% [CI] 0.04-0.26, P = .000). There was no statistically significant difference in median overall survival: 23.82 (95% CI 22.38-25.25) months in the metronomic capecitabine group vs 21.81 (95% CI 20.23-23.38) months in the observation group (hazard ratio 0.49, 95% CI 0.21-1.11, P = .087). Subgroup analyses were generally consistent with the primary finding. Similar safety profiles were observed in both arms. The most frequent adverse events in metronomic capecitabine group included neutropenia, diarrhea, hand-foot skin reaction, and mucositis.Maintenance therapy with metronomic capecitabine can be considered an alternative option following first-line chemotherapy of XELOX in patients with metastatic colorectal cancer with controlled toxicities.

Abstract
BACKGROUND Peripheral neurotoxicity (PN) is a frequent side effect of oxaliplatin treatment, and also is its dose-limiting toxicity. Studies have confirmed that ω-3 polyunsaturated fatty acids (ω-3 PUFAs) had a neuroprotective effect. However, the efficacy of ω-3 PUFAs on the prevention of oxaliplatin-related neurotoxicity remains unclear. We assessed the effect of ω-3 PUFAs on the neurotoxicity in colon cancer patients treated by oxaliplatin combined with capecitabine. METHODS In a randomized, double-blind, placebo-controlled study, 179 patients with colon cancer receiving oxaliplatin combined with capecitabine were recruited, and randomly assigned to take ω-3 PUFAs, 640 mg t.i.d during chemotherapy and 1 month after the end of the treatment or placebo. All patients were treated with chemotherapy for 6 treatment cycles. The incidence and severity of PN were evaluated, and the nerve conduction was measured before the onset of chemotherapy and 1 month after treatment. In addition, the quality of life was also accessed using Chinese version of European organization for research and treatment of cancer quality of life questionnaire. RESULTS The incidence of PN in the ω-3 PUFAs group and placebo group was 52.22% and 69.66%, respectively (P = .017). In addition, there was a significant difference in the severity of PN between the 2 groups (P = .017). In terms of motor and sensory nerve conduction, the sensory action potentials amplitude of sural nerve in the ω-3 PUFAs group and placebo group after chemotherapy treatment were (15.01 ± 3.14) and (13.00 ± 3.63) μ V respectively, suggesting there was a significant difference in the 2 groups (P = .000). In addition, the mean score of the global health-status/quality of life was obviously higher in the ω-3 PUFAs group than that in the placebo group. CONCLUSION ω-3 PUFAs seem to reduce the incidence and severity of oxaliplatin-related neurotoxicity, and improve the quality of patients' life, indicating it is expected to be a potential drug for the treatment of oxaliplatin-related neurotoxicity.

Abstract
BACKGROUND A prospective, pooled analysis of six randomised phase 3 trials was done to investigate disease-free survival regarding non-inferiority of 3 months versus 6 months of adjuvant chemotherapy for patients with stage III colon cancer; non-inferiority was not shown. Here, we report the final overall survival results. METHODS In this prospective, pooled analysis of six randomised phase 3 trials, we included patients with stage III colon cancer aged at least 18 years with an Eastern Cooperative Oncology Group performance status of 0-1 recruited between June 20, 2007, and Dec 31, 2015, across 12 countries in the CALGB/SWOG 80702, IDEA France, SCOT, ACHIEVE, TOSCA, and HORG trials, who started any treatment (modified intention-to-treat). Patients in all trials were randomly assigned to 3 months or 6 months of adjuvant fluorouracil, leucovorin, and oxaliplatin (FOLFOX) every 2 weeks or capecitabine and oxaliplatin (CAPOX) in different doses and methods every 3 weeks, at the treating physician's discretion. The primary endpoint was disease-free survival (time to relapse, secondary colorectal primary tumour, or death due to all causes), and overall survival (time to death due to all causes) was the prespecified secondary endpoint. The non-inferiority margin for overall survival was set as a hazard ratio (HR) of 1·11. Pre-planned subgroup analyses included regimen and risk group. Non-inferiority was declared if the one-sided false discovery rate adjusted (FDRadj) p value was less than 0·025. FINDINGS With median follow-up of 72·3 months (IQR 72·2-72·5), 2584 deaths among 12 835 patients were observed. 5064 (39·5%) patients received CAPOX and 7771 (60·5%) received FOLFOX. 5-year overall survival was 82·4% (95% CI 81·4-83·3) with 3 months of therapy and 82·8% (81·8-83·8) with 6 months of therapy (HR 1·02 [95% CI 0·95-1·11]; non-inferiority FDRadj p=0·058). For patients treated with CAPOX, 5-year overall survival was 82·1% (80·5-83·6) versus 81·2% (79·2-82·9; HR 0·96 [0·85-1·08]); non-inferiority FDRadj p=0·033), and for patients treated with FOLFOX 5-year overall survival was 82·6% (81·3-83·8) and 83·8% (82·6-85·0; HR 1·07 [0·97-1·18]; non-inferiority FDRadj p=0·34). Updated disease-free survival results confirmed previous findings (HR 1·08 [95% CI 1·02-1·15]; non-inferiority FDRadj p=0·25). Data on adverse events were not further recorded. INTERPRETATION Non-inferiority of 3 months versus 6 months of adjuvant chemotherapy for patients with stage III colon cancer was not confirmed in terms of overall survival, but the absolute 0·4% difference in 5-year overall survival should be placed in clinical context. Overall survival results support the use of 3 months of adjuvant CAPOX for most patients with stage III colon cancer. This conclusion is strengthened by the substantial reduction of toxicities, inconveniencies, and cost associated with a shorter treatment duration. FUNDING US National Cancer Institute.

Abstract
BACKGROUND Esophageal cancer is increasingly common and carries a poor prognosis. The optimal treatment modality for locally advanced cancer is unknown, with current guidance recommending either neoadjuvant chemotherapy (CT) or chemoradiotherapy (CRT) followed by surgery. There is a lack of adequately powered trials comparing CT against CRT. We retrospectively compared CT versus CRT using a propensity score weighting approach. METHODS Demographic, disease, treatment and outcome data were retrieved from a local database for patients who received neoadjuvant CT or CRT followed by surgery. Inverse probability of treatment weighting (IPTW) was used to balance groups using a propensity score-weighting approach. Groups were assessed for differences in postoperative outcomes and survival. Kaplan-Meier and non-parametric tests were used to compare survival and outcome data as appropriate. RESULTS Data for 284 patients were retrieved. Following IPTW groups were well matched. No significant differences were seen for postoperative complications (CT 64.9% vs. CRT 63.3%, p = 0.807), including major complications (24.0% vs. 23.6%, p = 0.943) and anastomotic leak (7.8% vs. 5.6%, p = 0.526). Significantly higher rates of clinical regression and complete pathological response were seen following CRT (p = 0.002 for both). Rates of R0 resection were higher with CRT, CT 79.1% vs. CRT 93.1%, p = 0.006. There was no difference between groups for overall or disease-free survival. CONCLUSION This study suggests that the significant improvements in local tumour response seen after neoadjuvant CRT compared to CT may not translate to different survival outcomes. However, it must be stressed that adequately powered prospective trials are still lacking.

Abstract
BACKGROUND The combination of chemotherapy plus anti HER-2 agents is the mainstay of HER-2 positive advanced breast cancer (ABC) therapy. We conducted a phase II trial testing activity and safety of trastuzumab and metronomic capecitabine/cyclophosphamide (HEX) as first-line therapy in HER-2 positive ABC.
Methods. Patients at first relapse or with synchronous metastasis were treated with trastuzumab (4 mg/kg, biweekly) plus oral capecitabine (1500 mg/daily) and cyclophosphamide (50 mg/daily). Primary endpoint was objective response rate (ORR), secondary endpoints progression-free survival (PFS), clinical benefit rate (CBR; PR + CR + SD for ≥ 24 weeks) and tolerability. Optimal two-stage design was applied. RESULTS Sixty patients with measurable ABC, tumors scored as +3 for HER-2 or FISH +, untreated for advanced disease were enrolled. Median age was 62.5 years, visceral metastases were present in most patients (57.9%). Median number of cycles was 16 (range 1-98). ORR was 56.7% (95% CI, 44.1-68.4%), with 5 CR (8.3%) and 29 PR (48.3%). Fifteen patients had SD (25%). The CBR was 78.2%. Nine progressions were observed (15%). Median PFS was 11 months. One year PFS was 47.7%. Median OS was 45.9 months. Worst toxicities were grade 3 hand-foot syndrome in 2 pts (3.3%), grade 3 anaemia in 2 pts (3.3%), grade 2 nausea in 2 pts (3.3%) and grade 3-4 diarrhea in 2 pts (3.3%). Cardiac toxicity grade 1 was reported in 1 pt. CONCLUSIONS Combination of trastuzumab and metronomic oral chemotherapy has clinical activity. The tolerability was excellent and allowed the prolonged delivery of treatment.

Abstract
AIMS Brain (central nervous system; CNS) metastases occur in 30-50% of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC). A substantive evidence base for treatment is lacking, but activity with lapatinib plus capecitabine (lap-cap) has been reported. We compared lap-cap with trastuzumab plus capecitabine (tras-cap) in patients with HER2-positive MBC with CNS metastases previously treated with trastuzumab. MATERIALS AND METHODS This open-label randomised phase II screening trial aimed to randomise 130 participants over 2 years to receive lap-cap or tras-cap. Eligible patients had HER2-positive MBC with newly diagnosed or recently progressed CNS metastases; previous, or current, treatment included: trastuzumab, a taxane or anthracycline and recent completion of local cranial therapy. The primary end point was time to progression of CNS metastases within the 24-week trial period. Secondary objectives included CNS response rate, progression-free survival, steroid use for CNS symptoms and feasibility of recruitment to a large phase III trial. RESULTS Between September 2011 and October 2013, 30 participants were randomised, 16 to lap-cap and 14 to tras-cap. Recruitment to a large phase III trial was determined not to be feasible. At 24 weeks, CNS disease progression was 41.8% (95% confidence interval 16.1-67.5%) in lap-cap and 41.2% (95% confidence interval 12.8-69.6%) in tras-cap arms; progression-free survival was 44.4% (95% confidence interval 18.1-70.8%) in lap-cap and 50.0% (95% confidence interval 20.9-79.1%) in tras-cap arms. CONCLUSION Poor recruitment confirmed that a larger phase III trial would not be feasible and prohibited a preliminary evaluation of the superiority of lap-cap over tras-cap. Descriptive statistics are presented to inform the limited evidence base and future study design.

Abstract
Chemotherapy is associated with different patterns of histopathological changes of the non-tumor-bearing liver. Hepatic infarction represents a relatively rare condition; the prevalence in several series of consecutive autopsies is 1.1%. To the best of our knowledge, no cases of liver infarction secondary to chemotherapy have been reported to date. We report a case of segmental hepatic infarction following the adjuvant chemotherapy with Oxaliplatin and Capecitabine in a patient who had undergone total gastrectomy and distal esophagectomy for gastric cancer. Liver infarction is usually managed by conservative therapy; interventional procedures such as percutaneous imaging-guided drainage or surgical evacuation should be reserved in cases where septic complications occur, with development of a hepatic abscess from the necrotic area. It is important to avoid misdiagnoses with liver metastases in order to define the most appropriate clinical management strategy.

Abstract
PURPOSE In the HER2CLIMB study, patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer with brain metastases (BMs) showed statistically significant improvement in progression-free survival (PFS) with tucatinib. We describe exploratory analyses of intracranial efficacy and survival in participants with BMs. PATIENTS AND METHODS Patients were randomly assigned 2:1 to tucatinib or placebo, in combination with trastuzumab and capecitabine. All patients underwent baseline brain magnetic resonance imaging; those with BMs were classified as active or stable. Efficacy analyses were performed by applying RECIST 1.1 criteria to CNS target lesions by investigator assessment. CNS-PFS (intracranial progression or death) and overall survival (OS) were evaluated in all patients with BMs. Confirmed intracranial objective response rate (ORR-IC) was evaluated in patients with measurable intracranial disease. RESULTS There were 291 patients with BMs: 198 (48%) in the tucatinib arm and 93 (46%) in the control arm. The risk of intracranial progression or death was reduced by 68% in the tucatinib arm (hazard ratio [HR], 0.32; 95% CI, 0.22 to 0.48; P < .0001). Median CNS-PFS was 9.9 months in the tucatinib arm versus 4.2 months in the control arm. Risk of death was reduced by 42% in the tucatinib arm (OS HR, 0.58; 95% CI, 0.40 to 0.85; P = .005). Median OS was 18.1 versus 12.0 months. ORR-IC was higher in the tucatinib arm (47.3%; 95% CI, 33.7% to 61.2%) versus the control arm (20.0%; 95% CI, 5.7% to 43.7%; P = .03). CONCLUSION In patients with HER2-positive breast cancer with BMs, the addition of tucatinib to trastuzumab and capecitabine doubled ORR-IC, reduced risk of intracranial progression or death by two thirds, and reduced risk of death by nearly half. To our knowledge, this is the first regimen to demonstrate improved antitumor activity against BMs in patients with HER2-positive breast cancer in a randomized, controlled trial.

Abstract
PURPOSE Neoadjuvant chemoradiotherapy has now become a standard treatment for rectal cancer. Recently, attempts have been made to predict the response rate to this treatment to decide whether or not it must be performed. However, tissue factors for predicting the response rate is not cohesively reviewed. METHODS Eighty-three patients with rectal cancer, all under neoadjuvant chemoradiotherapy and subsequent surgery, were examined for tissue factors in the biopsy sample. The tissue factors examined include tumor differentiation grade, lymphovascular invasion, perineural invasion, pathological stage, and lymphocytic infiltration. Lymphocytic infiltration was investigated by immunohistochemistry for CD8 T lymphocyte in biopsy samples. RESULTS In this study, tissue factors were found to play a decisive role in predicting response to neoadjuvant treatment. The most important factor was the pathological stage, which has the highest correlation with response to treatment. There is a significant relationship between CD8 lymphocyte infiltration and response to treatment (P value = 0.018). Primary perineural invasion and lymphovascular invasion also have a significant meaningful relationship with response to treatment (P value = 0.021 and P value = 0.036). CONCLUSION In this study, it was determined that the investigated factors have a significant relationship with response to treatment and could be used to predict the response to treatment, and if a low possibility of positive response exists, prevention of the complications of neoadjuvant chemoradiotherapy for the patients could occur.

Abstract
PURPOSE OF REVIEW The modalities of management of resectable pancreatic ductal adenocarcinoma (PDAC) have evolved in recent years with new practice guidelines on adjuvant chemotherapy and results of randomized phase III trials. The aim of this review is to describe the state of the art in this setting and to highlight future possible perspectives. RECENT FINDINGS Resectable PDAC is the tumor without vascular contact or a limited venous contact without vein irregularity. Several pathologic and biologic robust prognostic factors such as an R0 resection defined by a margin at least 1 mm have been validated. In phase III trials, the doublet gemcitabine-capecitabine provided a statistically significant, albeit modest overall survival benefit, but failed to show an improvement in relapse-free survival. Similarly, gemcitabine plus nab-paclitaxel did not increase disease-free survival. Modified FOLFIRINOX led to improved disease-free survival, overall survival, and metastasis-free survival, with acceptable toxicity. In the future, prognostic and/or predictive biomarkers could lead the optimization of therapeutic strategies and neoadjuvant treatment could become a standard of care in PDAC. SUMMARY After curative intent resection, modified FOLFIRINOX is the standard of care in adjuvant in fit patients with PDAC. Others regimens (monotherapy or gemcitabine-based) are an option in unfit patients.

Abstract
IMPORTANCE Fluorouracil-based chemotherapy combined with anti-epidermal growth factor receptor/vascular endothelial growth factor therapy is the standard first-line treatment for metastatic colorectal cancer followed by low-intensity maintenance therapy to balance the clinical efficacy and adverse effects (AEs). However, there have been concerns about the AEs of capecitabine plus cetuximab as a maintenance therapy in patients with RAS wild-type metastatic colorectal cancer. OBJECTIVE To evaluate the biological activity and safety of capecitabine plus cetuximab as a novel maintenance therapy for RAS wild-type metastatic colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This phase 2 prospective clinical trial was conducted from April 29, 2016, to April 29, 2019, at 5 centers in China. Patients diagnosed as having RAS wild-type metastatic colorectal cancer were recruited to receive fluorouracil-based cytotoxic agents combined with cetuximab followed by capecitabine plus cetuximab for maintenance therapy. Forty-seven patients with histologically confirmed metastatic colorectal cancer and genetic test results showing a wild-type RAS were enrolled in maintenance therapy. INTERVENTIONS Induction therapy for patients with RAS wild-type metastatic colorectal cancer was 8 to 12 cycles of fluorouracil-based chemotherapy combined with cetuximab. After stable disease status or better was achieved, reduced-dose capecitabine plus cetuximab was administered for maintenance therapy. MAIN OUTCOMES AND MEASURES The primary end point was progression-free survival during maintenance therapy. The secondary end points were total progression-free survival, overall survival, quality of life, safety, and toxic effects of treatment. RESULTS Forty-seven patients were enrolled in maintenance therapy, with a median age of 52 years (range, 25-81 years) and 32 (68%) of them being men. The median maintenance progression-free survival was 7.2 (95% CI, 5.8-8.6) months. The median progression-free survival was 12.7 (95% CI, 11.8-15.4) months. The median overall survival was 27.4 (95% CI, 21.4-35.5) months. Grade 3 to 4 AEs during induction therapy included neutropenia (4 patients [9%]), diarrhea (4 patients [9%]), nausea or vomiting (3 patients [6%]), rash acneiform (10 patients [21%]), and hand-foot syndrome (8 patients [17%]). Grade 3 to 4 AEs during maintenance therapy included diarrhea (2 patients [4%]), rash acneiform (8 patients [17%]), and hand-foot syndrome (5 patients [11%]). CONCLUSIONS AND RELEVANCE Reduced-dose capecitabine plus cetuximab after initial chemotherapy is a novel maintenance therapy for patients with RAS wild-type metastatic colorectal cancer that achieved good outcomes and tolerable nonserious AEs. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02717923.

Abstract
RATIONALE Pyrotinib is a novel dual pan-ErbB receptor tyrosine kinase inhibitor, approved for the treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC). However, there was still limited information regarding specific effect of pyrotinib on HER2-positive MBC patients with phosphoinositol-3 kinase mutation. PATIENT CONCERNS A 63-year-old woman accidentally discovered a left breast lesion. The breast cancer was diagnosed by biopsy of breast lesion and postoperative pathological examination in March, 2017. The patient was presented with HER2-positive (3+), invasive carcinoma of the left breast with lymph nodes and lung nodules metastasis, and the clinical stage was T4N2M1. However, the lesion continued to aggressive disease progression with the treatment of trastuzumab plus multiple chemotherapy regimens and traditional Chinese medicine. DIAGNOSES The woman was diagnosed with invasive carcinoma of the left breast and lymph nodes and lung nodules metastasis. INTERVENTIONS The patient received 6 cycles of pyrotinib in combination with capecitabine regularly. OUTCOMES Progression free survival was more than 6 months, and the patient's efficacy evaluation was partial remission. LESSONS Our clinical observations demonstrated that pyrotinib may be an effective treatment for patients with HER2-positive MBC.

Abstract
BACKGROUND We previously reported the HERBIS-4A phase II trial comparing S-1 plus cisplatin (SP) with capecitabine plus cisplatin (XP) in chemotherapy-naïve patients with HER2-negative advanced gastric cancer (GC). We performed a pooled analysis of HERBIS-4A and HERBIS-2, the phase II trial comparing SP with XP in HER2-negative recurrent GC patients with a recurrence-free interval after S-1 adjuvant therapy of ≥ 6 months. PATIENTS AND METHODS Patients were randomly assigned to receive either SP [S-1 (40-60 mg twice daily for 21 days) plus cisplatin (60 mg/m2 on day 8), every 5 weeks] or XP [capecitabine (1000 mg/m2 twice daily for 14 days) plus cisplatin (80 mg/m2 on day 1), every 3 weeks]. RESULTS In the pooled analysis, SP (n = 44-50) showed a longer progression-free survival [6.4 versus 5.1 months; hazard ratio (HR), 0.666; P = 0.062], overall survival (14.8 versus 10.6 months; HR, 0.695; P = 0.099), and time to treatment failure (4.6 versus 3.6 months; HR, 0.668; P = 0.045) as well as a higher disease control rate (86.4% versus 68.1%, P = 0.149) compared with XP (n = 47-51). A significant survival advantage for SP over XP was apparent in patients with a performance status of 0, a differentiated-type tumor histology, or a primary tumor localization to the upper portion of the stomach. CONCLUSION Our pooled analysis supports the use of SP in the first-line setting for patients with HER2-negative advanced or recurrent GC with a recurrence-free interval of ≥ 6 months. CLINICAL TRIAL REGISTRATION The HERBIS-2 trial was registered with UMIN-CTR as UMIN000006105.

Abstract
PURPOSE Capecitabine is a prodrug that undergoes metabolism in three steps to form an active 5-fluorouracil (5-FU). The first step is primarily catalyzed by liver carboxylesterases (CES) 1. Here, we examined the effects of CES1 variants on pharmacokinetics and toxicity of capecitabine. METHODS We enrolled postoperative colorectal cancer (CRC) patients administered with adjuvant capecitabine plus oxaliplatin (CapeOX) and metastatic CRC patients receiving CapeOX. The pharmacokinetic analysis of the first capecitabine dose (1000 mg/m2) was done on day 1, and oxaliplatin administration was shifted to day 2. Plasma concentrations of capecitabine, 5'-deoxy-5-fluorocytidine, 5'-deoxy-5-fluorouridine (5'-DFUR), and 5-FU were analyzed by high-performance liquid chromatography. CES1 polymorphisms (rs3217164, rs2244614, rs2244613, rs7187684, and rs11861118) and the functional CES1 genes (1A1, var1A1, 1A2, and pseudo 1A3) in their diplotype configurations were analyzed by direct sequencing. RESULTS Thirty-seven patients were enrolled from September 2017 to February 2020. Patients with a higher area under the plasma concentration-time curve to capecitabine dose ratio (AUC/dose) of 5'-DFUR than its mean showed a higher frequency of overall ≥ grade 3 toxicity and lower relative dose intensity (RDI) of capecitabine than those with a lower ratio. Higher CES1 activity expressed as a metabolic ratio (AUC of capecitabine/sum of three AUCs of each metabolite) lower than its mean was associated with higher 5'-DFUR AUC/dose and lower RDI, indicating essential roles of CES1 in capecitabine activation to produce 5'-DFUR. However, the association between CES1 variants and capecitabine pharmacokinetics and toxicity was not significant. CONCLUSION CES1 variants are not associated with capecitabine pharmacokinetics and toxicity.

Abstract
BACKGROUND The impact of using adjuvant chemotherapy following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with appendiceal adenocarcinoma is not known. The aim of this study was to assess the impact of adjuvant chemotherapy following complete cytoreduction in patients with appendiceal adenocarcinoma. METHODS Retrospective medical record review of all patients with appendiceal adenocarcinoma treated at our institution between 2006 and 2015. Kaplan-Meier plots were used to summarize overall survival (OS) and relapse-free survival over time, and log-rank tests and Cox proportional hazards models were used to test for differences in survival between groups. RESULTS A total of 103 patients with appendiceal adenocarcinoma received care at our institution during the study period. Complete cytoreduction (cytoreductive score 0-1) was achieved in 68 patients (66%). Of these 68 patients, 26 received adjuvant chemotherapy. The most common regimens were capecitabine (n = 11), capecitabine plus oxaliplatin (n = 7), and 5-FU plus oxaliplatin (n = 6). Tumor histopathology and grade, and the ability to achieve complete cytoreduction were significant predictors of overall survival. The median OS for non-low-grade and well-differentiated tumor patients who received adjuvant chemotherapy following complete cytoreduction was 9.03 years, compared to 2.88 years for patients who did not receive adjuvant chemotherapy (P = .02). Among low-grade and well-differentiated tumor patients who underwent complete cytoreduction, there was no statistically significant difference in OS between those who received adjuvant chemotherapy and those who did not. CONCLUSION Adjuvant chemotherapy seems to have benefit in appendiceal cancer patients with non-low-grade or well-differentiated tumor type but not in low-grade or well-differentiated tumors.

Abstract
PURPOSE Peripheral neuropathy (PN) is an intractable side effect of oxaliplatin, with no effective prophylaxis so far. Ninjin'yoeito (NYT), a Kampo medicine, is protective against oxaliplatin-induced neuronal cell injury in vitro and ameliorates oxaliplatin-induced PN in vivo. Thus, this randomized controlled trial was aimed at clarifying NYT's prophylactic effect for oxaliplatin-induced cumulative PN. METHODS 52 patients with colorectal cancers of pathological stage 3 received postoperative adjuvant chemotherapy with the CapeOX regimen: eight cycles of capecitabine (2400 mg/m2) plus oxaliplatin (130 mg/m2) at 3-week intervals. They were randomly assigned to NYT administration and non-administration groups. NYT (9.0 g/day) was administered from day 1 of cycle 1 in the NYT group. The NYT was administered orally daily throughout each cycle. The primary endpoint was the grade of cumulative PN at the end of eight cycles. The secondary endpoints included relative dose intensity (RDI) of oxaliplatin, recurrence-free survival (RFS), and overall survival (OS). RESULTS 40 patients (n = 20 in both groups) completed 8 chemotherapy cycles. The incidence of grade 2 or greater cumulative PN at the 8th chemotherapy cycle was significantly lower in the NYT group (2/20, 10.0%) than in the control group (11/20, 55.0%, P < 0.01). RDI of oxaliplatin was significantly higher in the NYT group than in the control group (P = 0.02). RFS and OS were better in the NYT group than in the control group, but the difference was not significant. CONCLUSIONS NYT may reduce the incidence of oxaliplatin-induced cumulative PN and facilitate maintenance of the CapeOX dosing regimen.

Abstract
BACKGROUND The interim analysis of the multicentre New EPOC trial in patients with resectable colorectal liver metastasis showed a significant reduction in progression-free survival in patients allocated to cetuximab plus chemotherapy compared with those given chemotherapy alone. The focus of the present analysis was to assess the effect on overall survival. METHODS New EPOC was a multicentre, open-label, randomised, controlled, phase 3 trial. Adult patients (aged ≥18 years) with KRAS wild-type (codons 12, 13, and 61) resectable or suboptimally resectable colorectal liver metastases and a WHO performance status of 0-2 were randomly assigned (1:1) to receive chemotherapy with or without cetuximab before and after liver resection. Randomisation was done centrally with minimisation factors of surgical centre, poor prognosis cancer, and previous adjuvant treatment with oxaliplatin. Chemotherapy consisted of oxaliplatin 85 mg/m2 administered intravenously over 2 h, l-folinic acid (175 mg flat dose administered intravenously over 2 h) or d,l-folinic acid (350 mg flat dose administered intravenously over 2 h), and fluorouracil bolus 400 mg/m2 administered intravenously over 5 min, followed by a 46 h infusion of fluorouracil 2400 mg/m2 repeated every 2 weeks (regimen one), or oxaliplatin 130 mg/m2 administered intravenously over 2 h and oral capecitabine 1000 mg/m2 twice daily on days 1-14 repeated every 3 weeks (regimen two). Patients who had received adjuvant oxaliplatin could receive irinotecan 180 mg/m2 intravenously over 30 min with fluorouracil instead of oxaliplatin (regimen three). Cetuximab was given intravenously, 500 mg/m2 every 2 weeks with regimen one and three or a loading dose of 400 mg/m2 followed by a weekly infusion of 250 mg/m2 with regimen two. The primary endpoint of progression-free survival was published previously. Secondary endpoints were overall survival, preoperative response, pathological resection status, and safety. Trial recruitment was halted prematurely on the advice of the Trial Steering Committee on Nov 1, 2012. All analyses (except safety) were done on the intention-to-treat population. Safety analyses included all randomly assigned patients. This trial is registered with ISRCTN, number 22944367. FINDINGS Between Feb 26, 2007, and Oct 12, 2012, 257 eligible patients were randomly assigned to chemotherapy with cetuximab (n=129) or without cetuximab (n=128). This analysis was carried out 5 years after the last patient was recruited, as defined in the protocol, at a median follow-up of 66·7 months (IQR 58·0-77·5). Median progression-free survival was 22·2 months (95% CI 18·3-26·8) in the chemotherapy alone group and 15·5 months (13·8-19·0) in the chemotherapy plus cetuximab group (hazard ratio [HR] 1·17, 95% CI 0·87-1·56; p=0·304). Median overall survival was 81·0 months (59·6 to not reached) in the chemotherapy alone group and 55·4 months (43·5-71·5) in the chemotherapy plus cetuximab group (HR 1·45, 1·02-2·05; p=0·036). There was no significant difference in the secondary outcomes of preoperative response or pathological resection status between groups. Five deaths might have been treatment-related (one in the chemotherapy alone group and four in the chemotherapy plus cetuximab group). The most common grade 3-4 adverse events reported were: neutrophil count decreased (26 [19%] of 134 in the chemotherapy alone group vs 21 [15%] of 137 in the chemotherapy plus cetuximab group), diarrhoea (13 [10%] vs 14 [10%]), skin rash (one [1%] vs 22 [16%]), thromboembolic events (ten [7%] vs 11 [8%]), lethargy (ten [7%] vs nine [7%]), oral mucositis (three [2%] vs 14 [10%]), vomiting (seven [5%] vs seven [5%]), peripheral neuropathy (eight [6%] vs five [4%]), and pain (six [4%] vs six [4%]). INTERPRETATION Although the addition of cetuximab to chemotherapy improves the overall survival in some studies in patients with advanced, inoperable metastatic disease, its use in the perioperative setting in patients with operable disease confers a significant disadvantage in terms of overall survival. Cetuximab should not be used in this setting. FUNDING Cancer Research UK.

Abstract
BACKGROUND Patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer who have disease progression after therapy with multiple HER2-targeted agents have limited treatment options. Tucatinib is an investigational, oral, highly selective inhibitor of the HER2 tyrosine kinase. METHODS We randomly assigned patients with HER2-positive metastatic breast cancer previously treated with trastuzumab, pertuzumab, and trastuzumab emtansine, who had or did not have brain metastases, to receive either tucatinib or placebo, in combination with trastuzumab and capecitabine. The primary end point was progression-free survival among the first 480 patients who underwent randomization. Secondary end points, assessed in the total population (612 patients), included overall survival, progression-free survival among patients with brain metastases, confirmed objective response rate, and safety. RESULTS Progression-free survival at 1 year was 33.1% in the tucatinib-combination group and 12.3% in the placebo-combination group (hazard ratio for disease progression or death, 0.54; 95% confidence interval [CI], 0.42 to 0.71; P<0.001), and the median duration of progression-free survival was 7.8 months and 5.6 months, respectively. Overall survival at 2 years was 44.9% in the tucatinib-combination group and 26.6% in the placebo-combination group (hazard ratio for death, 0.66; 95% CI, 0.50 to 0.88; P = 0.005), and the median overall survival was 21.9 months and 17.4 months, respectively. Among the patients with brain metastases, progression-free survival at 1 year was 24.9% in the tucatinib-combination group and 0% in the placebo-combination group (hazard ratio, 0.48; 95% CI, 0.34 to 0.69; P<0.001), and the median progression-free survival was 7.6 months and 5.4 months, respectively. Common adverse events in the tucatinib group included diarrhea, palmar-plantar erythrodysesthesia syndrome, nausea, fatigue, and vomiting. Diarrhea and elevated aminotransferase levels of grade 3 or higher were more common in the tucatinib-combination group than in the placebo-combination group. CONCLUSIONS In heavily pretreated patients with HER2-positive metastatic breast cancer, including those with brain metastases, adding tucatinib to trastuzumab and capecitabine resulted in better progression-free survival and overall survival outcomes than adding placebo; the risks of diarrhea and elevated aminotransferase levels were higher with tucatinib.

Abstract
BACKGROUND Response rates to single agent immune checkpoint blockade in unselected pretreated HER2-negative metastatic breast cancer (MBC) are low. However, they may be augmented when combined with chemotherapy. METHODS We conducted a single-arm, phase II study of patients with triple negative (TN) or hormone receptor-positive endocrine-refractory (HR+) MBC who were candidates for capecitabine. Patients were treated with pembrolizumab 200 mg intravenously day 1 and capecitabine 1000 mg/m2 by mouth twice daily on days 1-14 of a 21-day cycle. The primary end point was median progression-free survival (mPFS) compared with historic controls and secondary end points were overall response rate (ORR), safety and tolerability. The study had 80% power to detect a 2-month improvement in mPFS with the addition of pembrolizumab over historic controls treated with capecitabine alone. RESULTS Thirty patients, 16 TN and 14 HR+ MBC, were enrolled from 2017 to 2018. Patients had a median age of 51 years and received a median of 1 (range 0-6) prior lines of therapy for MBC. Of 29 evaluable patients, the mPFS was 4.0 (95% CI 2.0 to 6.4) months and was not significantly longer than historic controls of 3 months. The median overall survival was 15.4 (95% CI 8.2 to 20.3) months. The ORR was 14% (n=4), stable disease (SD) was 41% (n=12) and clinical benefit rate (CBR=partial response+SD>6 months) was 28% (n=8). The ORR and CBR were not significantly different between disease subtypes (ORR 13% and 14%, CBR 25% and 29% for TN and HR+, respectively). The 1-year PFS rate was 20.7% and three patients have ongoing responses. The most common adverse events were low grade and consistent with those seen in MBC patients receiving capecitabine, including hand-foot syndrome, gastrointestinal symptoms, fatigue and cytopenias. Toxicities at least possibly from pembrolizumab included grade 3 or 4 liver test abnormalities (7%), rash (7%) and diarrhea (3%), as well as grade 5 hepatic failure in a patient with liver metastases. CONCLUSIONS Compared with historical controls, pembrolizumab with capecitabine did not improve PFS in this biomarker unselected, pretreated cohort. However, some patients had prolonged disease control. TRIAL REGISTRATION NUMBER NCT03044730.

Abstract
OBJECTIVE Treatment options for HER-2-positive metastatic breast cancer (mBC) patients have expanded markedly since trastuzumab approval in 1998. Several other regimens are now available, including pertuzumab plus trastuzumab plus docetaxel, T-DM1, capecitabine plus lapatinib, and trastuzumab plus lapatinib. This study assesses the cost-effectiveness of four treatment sequences for HER-2-positive mBC according to the Taiwanese National Health Insurance Administration (TNHIA). METHODS Costs (U.S. Dollars) and effectiveness (quality-adjusted life years) of four treatment sequences for HER-2-positive mBC patients were examined using a Markov model over a lifetime horizon. Transition probabilities, disease progression, and probability of adverse events and survival were derived from clinical trial data. Costs and health utilities were estimated from TNHIA, Taipei Medical University Hospital, and the literature. Deterministic, probabilistic sensitivity analyses and a scenario analysis examined parameter uncertainty and accounted for drug wastage in dosage and cost calculations. RESULTS Sequence 3 (1st line: trastuzumab plus docetaxel; 2nd line: T-DM1; 3rd line: trastuzumab plus lapatinib) was the most cost-effective sequence followed by sequence 1 (1st line: pertuzumab plus trastuzumab plus docetaxel; 2nd line: T-DM1; 3rd line: capecitabine plus lapatinib), and sequence 4 (1st line: trastuzumab plus docetaxel; 2nd line: trastuzumab plus lapatinib; 3rd line: trastuzumab plus capecitabine), respectively. The model was sensitive to costs and transition probabilities, but not particularly sensitive to the wastage assumption. CONCLUSIONS From the perspective of the TNHIA, trastuzumab plus docetaxel as 1st line followed by T-DM1 and trastuzumab plus lapatinib as 2nd and 3rd line represents the most cost-effective strategy among the four sequences considered for treating HER-2-positive mBC patients.

Abstract
PURPOSE We aimed to identify potential clinical parameters that can be easily obtained by a pre-treatment clinicopathological evaluation and whole blood test to estimate the development of oxaliplatin-induced peripheral neuropathy (OIPN). METHODS This study was conducted retrospectively. For the FOLFOX regimen, patients received oxaliplatin, 85 mg/m2, every 2 weeks for 12 courses, and with the XELOX regimen, oxaliplatin was 130 mg/m2, every 3 weeks for 6-8 courses. The incidence and degree of neuropathy (NCI-CTCAE v.3) were recorded. RESULTS A total of 186 patients were included in the study. There were 108 (58%) patients in the grade 0-1 (G0-G1) neuropathy group (mean age 50.5 ± 11.5; 63% men), and 78 (42%) patients in the grade 2-3 (G2-G3) neuropathy group (mean age 58.0 ± 10.8; 46.2% men). The relationship between G2-G3 OIPN development and age (p < 0.001), gender (p = 0.02), and ECOG performance status (p = 0.007) was statistically significant. In the G2-G3 neuropathy group, serum gamma-glutamyl transferase (GGT) (p < 0.001) and glucose (p = 0.007) levels were higher, whereas vitamin D (p < 0.001), hemoglobin (Hgb) (p < 0.001), serum albumin (p = 0.001), and serum magnesium (p = 0.035) levels were lower compared with the G0-G1 neuropathy group. G2-G3 neuropathy was observed in 88% of patients with mucinous carcinoma pathologic type (p < 0.001). CONCLUSION This study demonstrated that age, histopathologic type, albumin, GGT, glucose, vitamin D, and Hgb levels were the effective factors in prediction of the development of OIPN. In addition, GGT, vitamin D, and Hgb levels were the most effective factor to predict development of OIPN.

Abstract
BACKGROUND Preclinical studies have suggested a synergistic effect of tamoxifen and capecitabine in estrogen receptor-positive cell lines. We evaluated the safety and efficacy of first-line chemoendocrine treatment in patients with metastatic breast cancer. Biochemical assessment was performed of serum levels of thymidine phosphorylase enzyme (TP), serum tamoxifen, hydroxytamoxifen, and 5-fluorouracil in relationship to efficacy. PATIENTS AND METHODS This prospective phase 2 interventional study studied patients with estrogen receptor-positive, HER2- metastatic breast cancer who received either tamoxifen/capecitabine or letrozole/capecitabine as first-line treatment. The dose of capecitabine provided at 2000 mg per day continuously as a fixed dose. RESULTS Forty women with a median age of 49.3 years were enrolled. For the whole study group, median progression-free survival (PFS) was 10 months and median overall survival (OS) was 23.3 months. The overall response rate was 60% and the clinical benefit rate 82.5%. Progesterone receptor positivity was associated with significantly longer PFS (12 vs. 7 months, P = .021). The most frequent adverse events were palmar-plantar erythrodysesthesia (62.5%), fatigue (62.5%), diarrhea (30%), abdominal pain (12.5%), and constipation (10%). Changes in serum level of TP were not correlated to response to treatment, PFS, or OS. Higher serum levels of tamoxifen and hydroxytamoxifen were correlated with higher response rates and longer PFS but not OS. CONCLUSION Chemoendocrine treatment is well tolerated, with no evidence of contradictory effects between the combination components. However, the efficacy data need more validation.
