Abstract
HER2-positive (HER2+) metastatic breast cancer (mBC) is highly aggressive and a major threat to human health. Despite the significant improvement in patients' prognosis given the drug development efforts during the past several decades, many clinical questions still remain to be addressed such as efficacy when combining different therapeutic modalities, best treatment sequences, interindividual variability as well as resistance and potential coping strategies. To better answer these questions, we developed a mechanistic quantitative systems pharmacology model of the pathophysiology of HER2+ mBC that was extensively calibrated and validated against multiscale data to quantitatively predict and characterize the signal transduction and preclinical tumor growth kinetics under different therapeutic interventions. Focusing on the second-line treatment for HER2+ mBC, e.g., antibody-drug conjugates (ADC), small molecule inhibitors/TKI and chemotherapy, the model accurately predicted the efficacy of various drug combinations and dosing regimens at the in vitro and in vivo levels. Sensitivity analyses and subsequent heterogeneous phenotype simulations revealed important insights into the design of new drug combinations to effectively overcome various resistance scenarios in HER2+ mBC treatments. In addition, the model predicted a better efficacy of the new TKI plus ADC combination which can potentially reduce drug dosage and toxicity, while it also shed light on the optimal treatment ordering of ADC versus TKI plus capecitabine regimens, and these findings were validated by new in vivo experiments. Our model is the first that mechanistically integrates multiple key drug modalities in HER2+ mBC research and it can serve as a high-throughput computational platform to guide future model-informed drug development and clinical translation.

Abstract
The endocrine therapy of hormone receptor (HR)-positive human epidermal growth factor receptor 2 (HER2)-negative breast cancer has stepped into an era of targeted combination therapy. Many targeted agents, led by cyclin-dependent kinase 4/6 inhibitor (CDK4/6i), have provided abundant treatment options for patients with HR-positive HER2-negative advanced breast cancer. To meet the needs of clinical practice in China and standardize the administration of targeted agents, the stratified endocrine strategy for advanced breast cancer has been proposed by Chinese Society of Clinical Oncology (CSCO) Breast Cancer guidelines based on medicine evidence and drug accessibility, offering scientific and organized decision-making guidance for clinical oncologists.

Abstract
Objective: To summarize the clinical use of palbociclib and evaluate its efficacy and safety in hormone-receptor (HR)-positive advanced breast cancer patients. Methods: We retrospectively analyzed data from 66 HR-positive metastatic breast cancer patients treated with palbociclib and endocrine therapy at the Department of Oncology in the First Affiliated Hospital with Nanjing Medical University between 2018 and 2020. We evaluated the factors affecting the efficacy of palbociclib using Kaplan-Meier method and Log-rank test for survival analysis and Cox regressions for multivariate analysis. Nomogram model was built for predicting prognosis among HR-positive breast cancer patients who received palbociclib. Concordance index (C-index) and calibration curve were used for internal validation to assess the predictive ability and conformity of the model. Results: Of the 66 patients treated with palbociclib, 33.3%(22), 42.4%(28) and 24.2%(16) patients were treated without endocrine therapy, first-line endocrine therapy, second-line or above endocrine therapy after recurrence, respectively. 36.4%(24) patients had hepatic metastasis, 16.7% (11) patients were sensitive to previous endocrine therapy, 27.3%(18/66) patients had primary resistance to endocrine therapy, while 56.1% (37) patients had secondary resistance to endocrine therapy. The overall response rate was 14.3% (95% CI: 6.7%, 25.4%) and clinical benefit rate was 58.7% (95% CI: 45.6%, 71.0%). Better clinical outcomes were associated with non-hepatic metastasis (P=0.001), sensitive/secondary resistant to previous endocrine therapy (P=0.004), no or only one line of chemotherapy for metastatic breast cancer (P=0.004), recent pathological confirmation of immunohistochemical analysis (P=0.025). Hepatic metastasis (P=0.005) and primary resistance to endocrine therapy (P=0.016) were the independent risk factors of progression free survival. The C-index of predictive probability for the nomogram constructed from the patient clinical characteristics (whether liver metastasis, whether primary endocrine resistance, lines of chemotherapy after metastasis, lines of endocrine therapy, number of metastatic sites, and time to last immunohistochemistry) to predict the progression-free survival at 6 and 12 months for patients was 69.7% and 72.1%, respectively. The most common adverse events were hematologic toxicities. Conclusions: Our report indicates that palbociclib combined with endocrine therapy for HR-positive recurrent metastatic breast cancer is effective and safe; patients with hepatic metastases and primary resistance to endocrine therapy have worse prognoses and are independent risk factors for progression after palbociclib therapy. The constructed nomogram could help predict the survival and guide the use of palbociclib.

Abstract
Objective This study aimed to explore possible associations between molecular subtypes and site of distant metastasis in advanced breast cancer (ABC). Methods 3577 ABC patients were selected from 21 hospitals of seven geographic regions in China from 2012-2014. A questionnaire was designed to collect medical information regarding demographic characteristics, risk factors, molecular subtype, recurrence/metastasis information, and disease-free survival (DFS). The cancers were classified into Luminal A, Luminal B, HER2-enriched and Triple Negative subtypes. Chi-square test and multivariate Cox proportional hazard models were performed to explore the associations between molecular subtypes and distant metastasis sites. Results A total of 2393 cases with molecular subtypes information were finally examined. Patients with Luminal A (51.1%) and Luminal B (44.7%) were most prone to bone metastasis, whereas liver metastasis was more frequently observed in HER2-enriched ABC patients (29.1%).The cumulative recurrence and metastasis rates of ABC patients at 36 months of DFS were the most significant within molecular types, of which Triple Negative was the highest (82.7%), while that of Luminal A was the lowest (58.4%). In the adjusted Cox regression analysis, Luminal B, HER2-enriched and Triple Negative subtypes increased the risk of visceral metastasis by 23%, 46% and 87% respectively. In addition, Triple Negative patients had a higher probability of brain metastasis (HR 3.07, 95% CI: 1.04-9.07). Conclusion Molecular subtypes can predict the preferential sites of distant metastasis, emphasizing that these associations were of great help in choices for surveillance, developing appropriate screening and cancer management strategies for follow-up and personalized therapy in ABC patients.

Abstract
Objective: To explore the application and efficacy of paclitaxel liposome in the treatment of advanced breast cancer among Chinese population in the real world. Methods: The clinical characteristics of patients with advanced breast cancer who received paclitaxel liposome as salvage treatment from January 1, 2016 to August 31, 2019 in 11 hospitals were collected and retrospectively analyzed. The primary outcome was progression free survival (PFS), and the secondary outcome included objective response rate (ORR) and safety. The survival curve was drawn by Kaplan-Meier analysis and the Cox regression model were used for the multivariate analysis. Results: Among 647 patients with advanced breast cancer who received paclitaxel liposome, the first-line treatment accounted for 43.3% (280/647), the second-line treatment accounted for 27.7% (179/647), and the third-line and above treatment accounted for 29.1% (188/647). The median dose of first-line and second-line treatment was 260 mg per cycle, and 240 mg in third line and above treatment. The median period of paclitaxel liposome alone and combined chemotherapy or targeted therapy is 4 cycles and 6 cycles, respectively. In the whole group, 167 patients (25.8%) were treated with paclitaxel liposome combined with capecitabine±trastuzumab (TX±H), 123 patients (19.0%) were treated with paclitaxel liposome alone (T), and 119 patients (18.4%) were treated with paclitaxel liposome combined with platinum ± trastuzumab (TP±H), 108 patients (16.7%) were treated with paclitaxel liposome combined with trastuzumab ± pertuzumab (TH±P). The median PFS of first-line and second-line patients (5.5 and 5.5 months, respectively) were longer than that of patients treated with third line and above (4.9 months, P<0.05); The ORR of the first line, second line, third line and above patients were 46.7%, 36.8% and 28.2%, respectively. Multivariate analysis showed that event-free survival (EFS) and the number of treatment lines were independent prognostic factors for PFS. The common adverse events were myelosuppression, gastrointestinal reactions, hand foot syndrome and abnormal liver function. Conclusion: Paclitaxel liposomes is widely used and has promising efficacy in multi-subtype advanced breast cancer.

Abstract
Background and Objective Triple negative breast cancer (TNBC) refers to a special subtype of breast cancer that is negative for the estrogen receptor, the progesterone receptors, and human epidermal growth factor receptor 2. As a group of diseases, it has strong heterogeneity. Refractory metastatic triple negative breast cancer (mTNBC) has even greater heterogeneity, more susceptibility to drug resistance, and faster progression, which makes it more difficult to treat effectively and significantly reduces a patient’s overall survival. Therefore, in order to overcome this difficulty in clinical practice, we need to deeply understand the special subgroup by analyzing definition and prognostic factors of refractory mTNBC and describing the therapeutic status and future treatment directions. Methods Recent domestic and foreign guidelines, as well as clinical studies related to refractory mTNBC on PubMed and the China National Knowledge Infrastructure (CNKI) databases were retrospectively analyzed. The six keywords we selected were used for literature search. Two authors performed database searches independently, and disagreements over the results were mediated by a third reviewer. Key Content and Findings According to the guidelines, refractory mTNBC has not been clearly defined. Related studies indicated that tumor heterogeneity may be one of the main mechanisms of early relapse or drug resistance in refractory mTNBC. The clinical treatment options for refractory mTNBC are very limited. Although chemotherapy is the standard treatment, it is limited by poor efficacy and intolerance in the clinical stage. Therefore, in recent years, many studies have explored novel treatment options. Both immunotherapy and poly(ADP-ribose) polymerase (PARP) inhibitors have been selected as first-line treatment in clinical studies, but gained limited benefits. Indeed, clinical studies have shown good efficacy with novel ADCs, which may be promising in the clinical treatment of refractory mTNBC. Conclusions Currently, improving the survival time and quality of life of refractory mTNBC are major challenges for clinicians. Novel therapies including immunosuppressive agents, PARP inhibitors, and ADCs rather than chemotherapy alone have achieved good results in the exploration of first-line treatment for refractory TNBC patients, but this warrants further research and investigation.

Abstract
Background Breast-conserving surgery followed by radiotherapy is recommended in most women with early-stage unilateral breast cancer. However, its role in contralateral breast cancer (CBC) patients remains unclear. This retrospective study aimed to evaluate the breast cancer-specific survival (BCSS) outcomes after breast-conserving surgery plus radiotherapy compared with mastectomy in women with early-stage (T1-2N0-1M0) CBC. Methods Data were extracted from the Surveillance, Epidemiology, and End Results database. BCSS was analyzed using the log-rank method, competing risks regression model, and propensity score matching method. Results A total of 9,336 early-stage CBC patients were included. After multivariable adjustment, no significant difference in BCSS was found between early-stage CBC patients undergoing breast-conserving surgery plus radiotherapy and those undergoing mastectomy [hazard ratio (HR) 1.11, 95% confidence interval (CI): 0.90-1.37, P=0.329]. BCSS was similar in both treatment groups and in the subgroups stratified by age at first primary breast cancer or CBC diagnosis (≤50, 51-60, and >60 years), time interval between cancers (<0.25, 0.25-4, 5-9, and ≤10 years), stage of first primary breast cancer, T classification of CBC, histology and hormone receptors status of both cancers (all P>0.05). Among patients with N1 disease at CBC diagnosis, breast-conserving surgery plus radiotherapy was associated with a boundary significantly improved BCSS (HR 1.45, 95% CI: 1.00-2.12, P=0.050). Among patients who underwent breast-conserving surgery for first primary cancer, bilateral mastectomy for contralateral cancer did not improve BCSS compared with breast-conserving surgery plus radiotherapy (P>0.05). There was no significant difference in BCSS between breast-conserving surgery plus radiotherapy and mastectomy plus radiotherapy (P>0.05). Stable results were obtained after propensity score matching. Conclusions Breast-conserving surgery plus radiotherapy did not significantly influence BCSS outcomes of patients with early-stage CBC. Bilateral mastectomy and mastectomy plus radiotherapy did not confer a survival advantage over breast-conserving surgery plus radiotherapy in these patients. Future prospective studies are necessary to expand on these results.

Abstract
OBJECTIVE To better understand the status of medical treatment for human epidermal growth factor receptor 2 (HER2)-positive breast cancer and the differences between the Chinese and the international clinical practice. METHODS This was a retrospective, nationwide, multicenter, epidemiological study of advanced breast cancer patients from China. Between January 01, 2012, and December 31, 2014, a total of 3649 patients, covering 7 geographic regions and 21 institutions, participated in this series of studies. HER2-positive breast cancer was selected among the group and adopted into this study. In comparison, we summarized the demographics and clinical characteristics of HER2-positive breast cancer from the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS A total of 918 patients diagnosed as HER2-positive breast cancer patients were included. The median age at diagnosis was 46 years (ranging, 23 to 78) with a single-peak incidence. The proportions of stages II-IV at diagnosis and distance metastasis in viscera were more than half of the participants. In comparison, the prevalence of estrogen or progesterone receptor-positive expression and luminalB subtype was relatively lower than that of the United States. The receipt of chemotherapy was fairly higher, while the usage of targeted therapy was seriously insufficient. Tumor size was in significantly positive associations with the duration of targeted therapy (Kendall's correlation coefficient = 0.3, P < 0.0001), while no prohibitive variables among clinical characteristics were detected. CONCLUSION Our study suggested that HER2-positive breast cancer patients were characterized as a younger trend, a lower prevalence of hormonal receptor (HR)-positive expression, and less accessible to anti-HER2 targeted therapy with insufficient duration over the past few years in China. Concerted efforts should be exerted for promising survival benefits in the future. The trial registration number is https://clinicaltrials.gov/ct2/show/NCT03047889.

Abstract
Abstract
Background: A phase 1 dose escalation study of TAA013, an antibody drug conjugate linking trastuzumab to a cytotoxic small molecule, DM1, through an SMCC linker, in previously treated recurrent Her2 positive breast cancer patients. Material and Methods: This phase I study follows the traditional 3+3 design, dosing started at 0.6mg/kg, followed by 1.2, 2.4, 3.6, 4.8mg/kg, one intravenous infusion was given every 3 weeks, the initial infusion had to be over 90 minutes, infusion times were later shortened if treatment was well tolerated. The subsequent recommended dose would be expanded to include at least 10 patients. Patients were observed for dose-limiting toxicity (DLT) during a 21-day DLT observation period. Toxicities were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events v5.0. Maximum-tolerated dose (MTD) was defined as the highest dose level that resulted in a DLT in no more than 1 of 6 patients. Study endpoints included safety and tolerability, pharmacokinetic and immunogenicity parameter evaluation, with preliminary evaluation of efficacy. Results: The study enrolled 22 female patients with histologically confirmed Her-2 positive metastatic breast cancer, median age of 50yrs (25-67), median time from initial diagnosis to TAA013 dosing was 39 months (5-99), median prior treatment regimen was 4 (2-10), all had received trastuzumab for a mean of 8.2 months (2-10), alone or in combination with chemotherapy, other prior Her2 targeting drugs given included pertuzumab (2), lapatinib (7), and pyrotinib (8). All patients received at least 2 (median of 6 infusions, range of 1-15) infusions, except for the last 4.8mg/kg patient, but all patients passed the dose limiting toxicity (DLT) observation period of 21 days. There were no dose limiting toxicities, no serious adverse events, nor that resulting in mortality, the maximum tolerated dose was not reached. The most common treatment emergent adverse events (TEAE) included 9 (40.9%) grade 1-2 infusion reactions associated with fever(5) and/or chills(1), the reaction often abated in subsequent cycles. There were no grade 4 TEAE, but there were 3 grade 3 thrombocytopenia, one grade 3 neutropenia, and one grade 3 hyperbilirubinemia which all recovered for the patients to continue treatment, there was also one grade 3 dermatitis in a patient with a history of chronic dermatitis. Antibody drug antibodies were not detected emanating from the TAA013 therapy. Pharmacokinetic studies included evaluation of TAA013, trastuzumab and DM1. Preliminary efficacy evaluation in the 2.4-4.8mg/kg dosing group of heavily pretreated patients resulted in 2 partial responses, including patients who had previously received pyrotinib therapy. Conclusion: TAA013 is a Her2 targeting antibody drug conjugate that is safe and tolerable, with efficacy demonstrated in heavily pretreated Her2 positive breast cancer patients. Keywords: breast cancer, antibody drug conjugates, TAA013.

Abstract
Cholesteryl hemisuccinate (CHS)-conjugated chitosan (CS)-based self-assembled nanoparticles (NPs) were developed for enhancing the intracellular uptake of docetaxel in multidrug resistance (MDR)-acquired cancer cells. CHS-CS was successfully synthesized and self-aggregation, particle size, zeta potential, drug entrapment efficiency, and in vitro drug release of docetaxel-loaded CHS-CS NPs were tested. The optimized NPs had a mean hydrodynamic diameter of 303 nm, positive zeta potential of 21.3 mV, and spherical shape. The in vitro release of docetaxel from the optimized CHS-CS NPs in different pH medium (pH 6.0 and 7.4) revealed that the release was improved in a more acidic condition (pH 6.0), representing a tumor cell's environment. The superior MDR-overcoming effect of docetaxel-loaded CHS-CS NPs, compared with docetaxel solution, was verified in anti-proliferation and cellular accumulation studies in MDR-acquired KBV20C cells. Thus, CHS-CS NPs could be potentially used for overcoming the MDR effect in anticancer drug delivery.

Abstract
Although receptor status including estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) of the primary breast tumors was related to the prognosis of breast cancer patients, little information is yet available on whether patient management and survival are impacted by receptor conversion in breast cancer metastases. Using data from the nation-wide multicenter clinical epidemiology study of advanced breast cancer in China (NCT03047889), we report the situation of retesting ER, PR and HER2 status for breast cancer metastases and evaluate the patient management and prognostic value of receptor conversion. In total, 3295 patients were analyzed and 1583 (48.0%) patients retesting receptor status for metastasis. Discordance in one or more receptors between the primary and the metastatic biopsy was found in 37.7% of women. Patients who remained hormone receptor (HR) positive in their metastases had similar progression-free survival of first-line and second-line treatment compared to patients with HR conversion (P > .05). In multivariate analysis, patients who showed ER conversion from negative to positive had longer disease-free survival (DFS) than patients who remained negative in their metastases (hazard ratio, 2.05; 95% confidence interval [CI], 1.45-2.90; P < .001). Patients with PR remained positive and had longer DFS than patients with PR conversion from negative to positive (hazard ratio, 0.56; 95% CI, 0.38-0.83; P = .004). Patients with PR conversion have shorter overall survival than patients with PR remained positive or negative (P = .016 and P = .041, respectively). Our findings showed that the receptors' conversions were common in metastatic breast cancer, and the conversion impacted the survival.

Abstract
Esophageal cancer (ESCC) is one of the most common causes of cancer-associated mortality in China. The present investigation reveals that non-coding RNAs (ncRNAs), including long ncRNAs (lncRNAs), exert a significant effect on the initiation, development and metastasis of malignant tumors, including ESCC. However, to the best of our knowledge, the function of non-protein-coding genes that host small nucleolar RNAs has not been investigated in cancer, particularly in ESCC. The expression of small nucleolar host gene 6 (SNHG6) in 70 ESCC tissues and paired adjacent tissues was measured by reverse transcription quantitative polymerase chain reaction. Analysis demonstrated that SNHG6 expression was significantly increased in ESCC tissues, and associated with tumor size (P=0.040) and Tumor-Node-Metastasis stage (P<0.01). Knockdown of SNHG6 may inhibit proliferative and colony-forming abilities, and induce apoptosis, in ESCC cells. To the best of our knowledge, the data from the present study indicated for the first time that SNHG6 was upregulated in ESCC tissues and cell lines. This novel lncRNA may exert a marked effect on the generation and progression of ESCC, potentially providing a novel perspective on ESCC diagnosis and management.

Abstract
BACKGROUND Platinum chemotherapy has a role in the treatment of metastatic triple-negative breast cancer but its full potential has probably not yet been reached. We assessed whether a cisplatin plus gemcitabine regimen was non-inferior to or superior to paclitaxel plus gemcitabine as first-line therapy for patients with metastatic triple-negative breast cancer. METHODS For this open-label, randomised, phase 3, hybrid-designed trial undertaken at 12 institutions or hospitals in China, we included Chinese patients aged 18-70 years with previously untreated, histologically confirmed metastatic triple-negative breast cancer, and an ECOG performance status of 0-1. These patients were randomly assigned (1:1) to receive either cisplatin plus gemcitabine (cisplatin 75 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1 and 8) or paclitaxel plus gemcitabine (paclitaxel 175 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1 and 8) given intravenously every 3 weeks for a maximum of eight cycles. Randomisation was done centrally via an interactive web response system using block randomisation with a size of eight, with no stratification factors. Patients and investigator were aware of group assignments. The primary endpoint was progression-free survival and analyses were based on all patients who received at least one dose of assigned treatment. The margin used to establish non-inferiority was 1·2. If non-inferiority of cisplatin plus gemcitabine compared with paclitaxel plus gemcitabine was achieved, we would then test for superiority. The trial is registered with ClinicalTrials.gov, number NCT01287624. FINDINGS From Jan 14, 2011, to Nov 14, 2013, 240 patients were assessed for eligibility and randomly assigned to treatment (120 in the cisplatin plus gemcitabine group and 120 in the paclitaxel plus gemcitabine group). 236 patients received at least one dose of assigned chemotherapy and were included in the modified intention-to-treat analysis (118 per group). After a median follow-up of 16·3 months (IQR 14·4-26·8) in the cisplatin plus gemcitabine group and 15·9 months (10·7-25·4) in the paclitaxel plus gemcitabine group, the hazard ratio for progression-free survival was 0·692 (95% CI 0·523-0·915; pnon-inferiority<0·0001, psuperiority=0·009, thus cisplatin plus gemcitabine was both non-inferior to and superior to paclitaxel plus gemcitabine. Median progression-free survival was 7·73 months (95% CI 6·16-9·30) in the cisplatin plus gemcitabine group and 6·47 months (5·76-7·18) in the paclitaxel plus gemcitabine group. Grade 3 or 4 adverse events that differed significantly between the two groups included nausea (eight [7%] vs one [<1%]), vomiting (13 [11%] vs one [<1%]), musculoskeletal pain (none vs ten [8%]), anaemia (39 [33%] vs six [5%]), and thrombocytopenia (38 [32%] vs three [3%]), for the cisplatin plus gemcitabine compared with the paclitaxel plus gemcitabine groups, respectively. In addition, patients in the cisplatin plus gemcitabine group had significantly fewer events of grade 1-4 alopecia (12 [10%] vs 42 [36%]) and peripheral neuropathy (27 [23%] vs 60 [51%]), but more grade 1-4 anorexia (33 [28%] vs 10 [8%]), constipation (29 [25%] vs 11 [9%]), hypomagnesaemia (27 [23%] vs five [4%]), and hypokalaemia (10 [8%] vs two [2%]). Serious drug-related adverse events were seen in three patients in the paclitaxel plus gemcitabine group (interstitial pneumonia, anaphylaxis, and severe neutropenia) and four in the cisplatin plus gemcitabine group (pathological bone fracture, thrombocytopenia with subcutaneous haemorrhage, severe anaemia, and cardiogenic syncope). There were no treatment-related deaths. INTERPRETATION Cisplatin plus gemcitabine could be an alternative or even the preferred first-line chemotherapy strategy for patients with metastatic triple-negative breast cancer.

Abstract
OBJECTIVES To evaluate levels of CD44 standard variant (CD44s), CD44 variant exon 3 (CD44v3) and CD44 variant exon 6 (CD44v6) protein in breast cancer tissue, and investigate their relationships with clinicopathological characteristics of the disease. METHODS Immunohistochemistry for CD44s, CD44v3 and CD44v6 was retrospectively performed on formalin-fixed paraffin wax-embedded breast cancer tissue samples. RESULTS Tumour tissue samples from 60 patients with breast cancer were included. There was a significant relationship between CD44s positivity and tumour diameter and lymph node involvement. CD44v6 positivity was significantly associated with tumour-node-metastasis (TNM) stage and lymph node involvement. There were significant negative correlations between CD44s immunopositivity, tumour diameter and TNM stage, and significant positive correlations between CD44v6 immunopositivity, tumour diameter and TNM stage. CONCLUSIONS CD44s and CD44v6 appear to play opposing roles in the development of breast cancer, but their precise functions and mechanisms of action remain unclear.

Abstract
Esophageal cancer is a highly frequent malignancy, being the fourth leading cause of cancer-related deaths in China. Most patients are initially diagnosed with advanced disease. Despite recent advances in surgical techniques and adjuvant/neoadjuvant radiotherapy and chemotherapy, the prognosis of esophageal cancer is still poor. An emerging understanding of molecular pathways that characterizes cell growth, cell cycle, apoptosis, angiogenesis, and invasion has provided novel targets for cancer therapy. This review focuses on novel targeted treatments for esophageal cancer.

Abstract
OBJECTIVE Cumulative evidence suggests that MLH1, the key component in the mismatch pathway, plays an important role in human cancers. Two potential functional polymorphisms (-93G>A and I219V) of MLH1 have been implicated in cancer risk. The aim of this meta-analysis was to summarize the evidence for associations. METHODS Eligible studies were identified by searching the electronic literature PubMed, ScienceDirect and Embase databases for relevant reports and bibliographies. Studies were included if of case-control design investigating MLH1 polymorphisms (-93G>A and I219V) and cancer risk with sufficient raw data for analysis. Odds ratios (OR) and 95% confidence intervals (95% CI) were used to evaluate the strength of associations. RESULTS Our meta-analysis from 33 published case-control studies showed the variant A allele of -93G>A polymorphism to be associated with increased risk in all genetic models (AA vs. GG: OR = 1.22, 95% CI: 1.03-1.44), especially among non-Asians (AA vs. GG: OR = 1.28, 95% CI: 1.04-1.58). For the I219V polymorphism, however, there was no main effect associated with overall cancer risk in any genetic model. CONCLUSIONS The meta-analysis suggested that the MLH1 -93G>A polymorphism may be a biomarker of cancer susceptibility. Large sample association studies and assessment of gene-to-gene as well as gene-to-environment interactions are required to confirm these findings.

Abstract
CD44 molecule plays critical role in distant malignant metastasis. It is expressed in standard form (CD44s) or variant form (CD44v). Tumor necrosis factor-α (TNF-α) is highly expressed in the cancer microenvironment. TNF-α was reported to modulate CD44 expression in several kinds of cancer. However, little is known about pathological role of TNF-α in breast cancer (BC) cells. In the current investigation, we investigated the effect of TNF-α on BC cells (MCF-7 and MDA-MB-231) viability, CD44 expression, and in vitro migration. We found that TNF-α down-regulated CD44s expression, up-regulated CD44v3 and CD44v6 expression through JNK pathway in MCF-7 cells. In MDA-MB-231 cells, TNF-α up-regulated CD44s, CD44v3 and CD44v6 expression via p38 pathway. These data indicate important role of CD44 molecule in BC pathology.

Abstract
Polo-like kinase 1 is a serine/threonine kinase which plays an essential role in mitosis and malignant transformation. The aim of this study was to investigate the prognostic significance of polo-like kinase 1 expression and determine its possibility as a therapeutic target in non-small cell lung cancer. Semi-quantitative RT-PCR assay was performed to detect polo-like kinase 1 mRNA expression in non-small cell lung cancer cells or tissues. Immunohistochemistry was performed to detect polo-like kinase 1 protein expression in 100 non-small cell lung cancer tissue samples, and the associations of polo-like kinase 1 expression with clinicopathological factors or prognosis of non-small cell lung cancer patients were evaluated. RNA interference was employed to inhibit endogenous polo-like kinase 1 expression and analyzed the effects of polo-like kinase 1 inhibition on the malignant phenotypes of non-small cell lung cancer cells including growth, apoptosis, radio- or chemoresistance. Also, the possible molecular mechanisms were also investigated. The levels of polo-like kinase 1 mRNA expression in non-small cell lung cancer cell lines or tissues were significantly higher than those in normal human bronchial epithelial cell line or corresponding non-tumor tissues. High polo-like kinase 1 expression was significantly correlated with advanced clinical stage, higher tumor classification and lymph node metastasis of non-small cell lung cancer patients (P=0.001, 0.004 and 0.001, respectively). Meanwhile, high polo-like kinase 1 protein expression was also an independent prognostic molecular marker for non-small cell lung cancer patients (hazard ratio: 2.113; 95% confidence interval: 1.326-3.557; P=0.017). Polo-like kinase 1 inhibition could significantly inhibit in vitro and in vivo proliferation, induce cell arrest of G(2)/M phase and apoptosis enhancement in non-small cell lung cancer cells, which might be activation of the p53 pathway and the Cdc25C/cdc2/cyclin B1 feedback loop. Further, inhibition of polo-like kinase 1 could enhance the sensitivity of non-small cell lung cancer cells to taxanes or irradiation. Thus, polo-like kinase 1 might be a prognostic marker and a chemo- or radiotherapeutic target for non-small cell lung cancer.

Abstract
Background Lung cancer is a malignant carcinoma which has the highest morbidity and mortality in Chinese population. Gefitinib, a tyrosine kinase (TK) inhibitor of epidermal growth factor receptor (EGFR), displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC) in Chinese population are not sufficient. Purpose To assess the efficacy and toxicity of gefitinib in Chinese patients with advanced non-small-cell lung cancer (NSCLC), a study of single agent treatment with gefitinib in Chinese patients was conducted. Methods 45 patients with advanced NSCLC were treated with gefitinib (250 mg daily) until the disease progression or intolerable toxicity. Results Among the 45 patients, 15 patients achieved partial response (PR), 17 patients experienced stable disease (SD), and 13 patients developed progression disease (PD). None of the patients achieved complete response (CR). The tumor response rate and disease control rate was 33% and 71.1%, respectively. Symptom remission rate was 72.5%, and median remission time was 8 days. Median overall survival and median progression-free survival was 15.3 months and 6.0 months, respectively. The main induced toxicities by gefitinib were skin rash and diarrhea (53.3% and 33.3%, respectively). The minor induced toxicities included dehydration and pruritus of skin (26.7% and 22.2%, respectively). In addition, hepatic toxicity and oral ulceration occurred in few patients (6.7% and 4.4%2, respectively). Conclusions Single agent treatment with gefitinib is effective and well tolerated in Chinese patients with advanced NSCLC.

Abstract
Bcl-xL, a member of Bcl-2 protein family functioned as dominant regulators of apoptotic cell death, has been reported to play important roles in malignant transformation and tumor development. In the present study, our aim was to explore the roles of Bcl-xL overexpression and determine its possibility as a therapeutic target in human osteosarcoma. Real-time quantitative RT-PCR and Western blot or immunohistochemistry assays were performed to detect the expression of Bcl-xL mRNA and protein in human osteosarcoma cell lines or tissue samples. The expression of other Bcl-2 family proteins (Bcl-2, Mcl-1, Bim and Bik) in osteosarcoma tissues was also detected by immunohistochemistry. The associations of Bcl-xL mRNA expression with clinicopathologic factors and prognosis of osteosarcoma patients were evaluated. RNA interference or gene overexpression technologies were employed to downregulate or upregulate endogenous Bcl-xL expression in osteosarcoma cells and the effects of Bcl-xL downregulation or upregulation on phenotypes and chemo- or radiosensitivity of human osteosarcoma cells were analyzed. Finally, the mechanism of synergistic effects of Bcl-xL downregulation and chemo- or radiotherapy was explored by detecting the activity of caspase-3. The expression levels of Bcl-xL mRNA and protein in high metastatic osteosarcoma cells showed higher than those in low metastatic osteosarcoma cells. Moreover, the levels of Bcl-xL mRNA expression were significantly higher in osteosarcoma tissues than those in chondroma or corresponding non-tumor tissues (P<0.01), and osteosarcoma tissues showed stronger immunostaining of Bcl-xL protein than non-tumor tissues. The stronger staining of Bcl-2 and Mcl-1 proteins was also observed, while the staining of pro-apoptotic proteins (Bim and Bik) was significantly weaker or not detected in osteosarcoma tissues. The higher levels of Bcl-xL mRNA expression were significantly correlated with advanced clinical stage (P=0.005) or hematogenous metastasis (P=0.001) of osteosarcoma patients. Osteosarcoma patients with higher Bcl-xL mRNA expression showed a poorer survival compared with those with lower expression (P=0.039). Bcl-xL downregulation or upregulation could significantly reduce or increase the proliferation capacity of osteosarcoma cells. Furthermore, Bcl-xL downregulation could significantly enhance in vitro chemo- or radiosensitivity of osteosarcoma cells, which might be associated with elevated activity of caspase-3. Taken together, overexpression of Bcl-xL may play important roles in osteosarcoma progression and this molecule will be a potential chemo- or radiotherapeutic molecular target for osteosarcoma therapy.

Abstract
BACKGROUND Amphiregulin (AREG) and epiregulin (EREG) have been found to play pivotal roles in several malignancies. However, the correlation between their expression and clinicopathological factors in colorectal carcinoma (CRC) is yet to be further investigated. To clarify the clinical significance of AREG and EREG expression in CRC, we detected serum and tissue levels of AREG and EREG. PATIENTS AND METHODS We detected serum AREG and EREG levels by ELISA, and tissue levels by immunohistochemical test in 73 patients with CRC. The correlation between each independent clinicopathological characteristic and AREG and EREG levels was examined. RESULTS There was significant correlation between serum AREG level and vascular invasion. There was no correlation between EREG serum level and any clinicopathological characteristics. Among the 73 primary lesions, 51 were AREG-positive, and 48 were EREG-positive. AREG-positive status was significantly correlated with depth of tumor invasion, distant metastases, and nerve invasion. EREG-positive status was significantly correlated with depth of tumor invasion and distant metastases. Coexpression analysis showed that 46 patients were both AREG-positive and EREG-positive. CONCLUSIONS High serum and tissue levels of AREG and high tissue level of EREG are predictors of a poor prognosis in patients with CRC.

Abstract
A mixed micelle that comprised of MPEG-PLA (MPP) and Pluronic copolymers was developed for enhanced bioavailability and to overcome multidrug resistance of docetaxel in cancer therapy. The mixed micelles that sufficiently solubilized docetaxel were evaluated for the effect of Pluronic copolymers weight ratio on the mixed micelles with respect to drug loading and drug release. In vitro, cell viability and cytotoxicity studies in KB and KBv cells revealed that the mixed micellar formulations were more potent than the commercial docetaxel formulation (Taxotere). In vivo pharmacokinetics study in rats showed that the mixed micelles significantly enhanced the bioavailability of docetaxel (3.6 fold) than Taxotere. Moreover, antitumor activity assessed in KBv cancer xenograft BALB/C nude mice models showed that the mixed micelles significantly reduced the tumor size than the control (Taxotere). Clear differences in the intracellular uptake of docetaxel between MPP and mixed micelles were observed using confocal laser scanning microscopy. This study presents not only a new micelle structure for a diblock-triblock copolymer system, but also a method for enhanced bioavailability of docetaxel and to overcome some of the limitations on its multidrug resistance in cancer therapy.

Abstract
OBJECTIVE To observe the influence of Salvia miltiorrhiza (SM) and Astragalus membranaceus (AM) on hemodynamics and liver fibrosis indexes in patients of liver cirrhosis with portal hypertension. METHODS Eighty-four cases of liver cirrhosis were enrolled and divided randomly into two groups, 42 in each. The control group was treated with conventional therapy and the tested group treated with SM and AM. The parameters, including diameter of portal vein and splenic vein (Dpv and Dsv), speed of blood flow in portal vein and splenic vein (Spv and Ssv), quantity of blood flow in portal vein and splenic vein (Qpv and Qsv) as well as liver fibrosis indexes, such as HA, PC III and LN, were determined before, 1, 2 and 3 months after treatment. RESULTS After treatment, in the tested group, Dpv and Dsv decreased, Spv and Ssv increased, and Qpv and Qsv reduced, showing a significant difference in comparison with those in the control group (P < 0.05 or P < 0.01). The liver fibrosis indexes were improved significantly in the tested group, also showed significant difference from those in the control group (P < 0.01). CONCLUSION SM and AM could improve portal hypertension effectively in liver cirrhosis patients, one of the mechanism may be related with the improvement of liver fibrosis.

Abstract
OBJECTIVE The objective of this investigation was to study the role of selective wrist arthrography of the asymptomatic wrists of patients with unilateral wrist pain and the efficacy of three-compartment and selective-compartment injections of contrast medium into the asymptomatic wrist in demonstrating symmetric and asymmetric intercarpal ligament and triangular fibrocartilage communicating defects. SUBJECTS AND METHODS Wrist arthrography with bilateral three-compartment injections was performed for 62 patients with unilateral wrist pain. The numbers of bilateral intercarpal ligament and triangular fibrocartilage communicating defects were recorded. The results obtained with three-compartment injections in each wrist of these patients were compared with those obtained with single-compartment injections. RESULTS Bilateral three-compartment injections identified 110 communicating defects (59 in the symptomatic and 51 in the asymptomatic wrists). Midcarpal injections showed all 36 scapholunate and lunatotriquetral ligament defects that were also shown by three-compartment injections in asymptomatic wrists. However, only 26 (72%) of these 36 ligament defects were shown by radiocarpal injections. No single-compartment injection showed all triangular fibrocartilage defects that were shown by three-compartment injections. Ten bilateral symmetric triangular fibrocartilage communicating defects were shown by three-compartment injections. All 10 triangular fibrocartilage communicating defects in asymptomatic wrists were shown by radiocarpal injections. However, only five of the 10 triangular fibrocartilage communicating defects in asymptomatic wrists were shown by injection of the distal radioulnar joints. CONCLUSION Selective midcarpal injection of an asymptomatic wrist showed all matching defects in that wrist when only intercarpal ligament defects were found in the symptomatic wrist. Similarly, selective radiocarpal injection of an asymptomatic wrist showed all matching defects of the triangular fibrocartilage in that wrist. In either situation, routine injection of all three compartments of the asymptomatic wrist should not be necessary.

Abstract
Biotransformation of 2-methoxyethanol (2-ME) by alcohol and aldehyde dehydrogenases is an established factor in the toxicity of this useful solvent. Little is known about potential capacity for 2-ME biotransformation by testis or other target tissues. We detected appreciable capacity for 2-ME biotransformation by alcohol dehydrogenase in testes from Sprague-Dawley rats. However, kinetic analysis showed a 6-fold lower affinity for 2-ME by alcohol dehydrogenase of testis compared to liver. 2-ME biotransformation was also detected in testes from Wistar rats and one strain of mice but not in testes from hamsters, guinea pigs, rabbits, dogs, cats or humans. Testes from all these species readily converted the aldehyde metabolite of 2-ME to 2-methoxyacetic acid. Hepatic capacities for 2-ME biotransformation by alcohol dehydrogenase varied from 22 to 2.5 mumol/mg prot/min with a species rank order of: hamsters >> rats = mice > guinea pigs = rabbits. There was no consistent concordance between activities for 2-ME versus ethanol, the prototype substrate for alcohol dehydrogenase, which could reflect substrate preferences of different isozymes. Species differences between rats and hamsters were also found for testicular and hepatic biotransformation of the glycol ethers, 2-ethoxyethanol and 2-butoxyethanol. Although species differences in capacity for 2-ME biotransformation were found, the observations do not provide an explanation for reported species and strain differences in susceptibility to 2-ME toxicity.
