Chen JH, Zhu LY, Cai ZW, Hu X, Ahmed AA, Ge JQ, Tang XY, Li CJ, Pu YL, Jiang CY. TRIANGLE operation, combined with adequate adjuvant chemotherapy, can improve the prognosis of pancreatic head cancer: A retrospective study. World J Gastrointest Oncol 2024; 16:1773-1786. [PMID: 38764839 PMCID: PMC11099462 DOI: 10.4251/wjgo.v16.i5.1773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/04/2024] [Accepted: 03/05/2024] [Indexed: 05/09/2024] Open
Abstract
BACKGROUND The TRIANGLE operation involves the removal of all tissues within the triangle bounded by the portal vein-superior mesenteric vein, celiac axis-common hepatic artery, and superior mesenteric artery to improve patient prognosis. Although previously promising in patients with locally advanced pancreatic ductal adenocarcinoma (PDAC), data are limited regarding the long-term oncological outcomes of the TRIANGLE operation among resectable PDAC patients undergoing pancreaticoduodenectomy (PD). AIM To evaluate the safety of the TRIANGLE operation during PD and the prognosis in patients with resectable PDAC. METHODS This retrospective cohort study included patients who underwent PD for pancreatic head cancer between January 2017 and April 2023, with or without the TRIANGLE operation. Patients were divided into the PDTRIANGLE and PDnon-TRIANGLE groups. Surgical and survival outcomes were compared between the two groups. Adequate adjuvant chemotherapy was defined as adjuvant chemotherapy ≥ 6 months. RESULTS The PDTRIANGLE and PDnon-TRIANGLE groups included 52 and 55 patients, respectively. There were no significant differences in the baseline characteristics or perioperative indexes between the two groups. Furthermore, the recurrence rate was lower in the PDTRIANGLE group than in the PDnon-TRIANGLE group (48.1% vs 81.8%, P < 0.001), and the local recurrence rate of PDAC decreased from 37.8% to 16.0%. Multivariate Cox regression analysis revealed that PDTRIANGLE (HR = 0.424; 95%CI: 0.256-0.702; P = 0.001), adequate adjuvant chemotherapy ≥ 6 months (HR = 0.370; 95%CI: 0.222-0.618; P < 0.001) and margin status (HR = 2.255; 95%CI: 1.252-4.064; P = 0.007) were found to be independent factors for the recurrence rate. CONCLUSION The TRIANGLE operation is safe for PDAC patients undergoing PD. Moreover, it reduces the local recurrence rate of PDAC and may improve survival in patients who receive adequate adjuvant chemotherapy.

Abstract
BACKGROUND Little is known about adjuvant therapy (AT) omission and use outside of randomized trials. We aimed to assess the patterns of AT omission and use in a cohort of upfront resected pancreatic cancer patients in a real-life scenario. METHODS From January 2019 to July 2022, 317 patients with resected pancreatic cancer and operated upfront were prospectively enrolled in this prospective observational trial according to the previously calculated sample size. The association between perioperative variables and the risk of AT omission and AT delay was analyzed using multivariable logistic regression. RESULTS Eighty patients (25.2%) did not receive AT. The main reasons for AT omission were postoperative complications (38.8%), oncologist's choice (21.2%), baseline comorbidities (20%), patient's choice (10%), and early recurrence (10%). At the multivariable analysis, the odds of not receiving AT increased significantly for older patients (odds ratio [OR] 1.1, p < 0.001), those having an American Society of Anesthesiologists score ≥II (OR 2.03, p = 0.015), or developing postoperative pancreatic fistula (OR 2.5, p = 0.019). The likelihood of not receiving FOLFIRINOX as AT increased for older patients (OR 1.1, p < 0.001), in the presence of early-stage disease (stage I-IIa vs. IIb-III, OR 2.82, p =0.031; N0 vs. N+, OR 3, p = 0.03), and for patients who experienced postoperative major complications (OR 4.7, p = 0.009). A twofold increased likelihood of delay in AT was found in patients experiencing postoperative complications (OR 3.86, p = 0.011). CONCLUSIONS AT is not delivered in about one-quarter of upfront resected pancreatic cancer patients. Age, comorbidities, and postoperative complications are the main drivers of AT omission and mFOLFIRINOX non-use. CLINICALTRIALS REGISTRATION NCT03788382.

Abstract
A meta-analysis was conducted to measure hepatic and pancreatic tumour resection (HPTR) risk factors (RFs) for surgical site wound infections (SSWIs). A comprehensive literature inspection was conducted until February 2023, and 2349 interrelated investigations were reviewed. The nine chosen investigations included 22 774 individuals who were in the chosen investigations' starting point, 20 831 of them were with pancreatic tumours (PTs), and 1934 with hepatic tumours (HTs). Odds ratio (OR) and 95% confidence intervals (CIs) were used to compute the value of the HPTR RFs for SSWIs using dichotomous and continuous approaches, and a fixed or random model. HT patients with biliary reconstruction had significantly higher SSWI (OR, 5.81; 95% CI, 3.42-9.88, P < .001) than those without biliary reconstruction. Nevertheless, there was no significant difference between individuals with PT who underwent pancreaticoduodenectomy and those who underwent distal pancreatectomy in SSWI (OR, 1.63; 95% CI, 0.95-2.77, P = .07). HT individuals with biliary reconstruction had significantly higher SSWI compared with those without biliary reconstruction. Nevertheless, there was no significant difference between PT individuals who underwent pancreaticoduodenectomy and those who underwent distal pancreatectomy in SSWI. However, owing to the small number of selected investigations for this meta-analysis, care must be exercised when dealing with its values.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest solid malignancies, with a five-year survival of less than 10%. The resistance of the disease and the associated lack of therapeutic response is attributed primarily to its dense, fibrotic stroma, which acts as a barrier to drug perfusion and permits tumour survival and invasion. As clinical trials of chemotherapy (CT), radiotherapy (RT), and targeted agents have not been successful, improving the survival rate in unresectable PDAC remains an urgent clinical need. Photodynamic stromal depletion (PSD) is a recent approach that uses visible or near-infrared light to destroy the desmoplastic tissue. Preclinical evidence suggests this can resensitise tumour cells to subsequent therapies whilst averting the tumorigenic effects of tumour-stromal cell interactions. So far, the pre-clinical studies have suggested that PDT can successfully mediate the destruction of various stromal elements without increasing the aggressiveness of the tumour. However, the complexity of this interplay, including the combined tumour promoting and suppressing effects, poses unknowns for the clinical application of photodynamic stromal depletion in PDAC.

Abstract
INTRODUCTION For PDAC patients undergoing resection, it remains unclear whether metastases to the paraaortic lymph nodes (PALN+) have any prognostic significance and whether metastases should lead to the operation not being carried out. Our hypothesis is that PALN + status would be associated with short overall survival (OS) compared with PALN-, but longer OS compared with patients undergoing surgical exploration only (EXP). METHODS Patients with registered PALN removal from the nationwide Danish Pancreatic Cancer Database (DPCD) from May 1st 2011 to December 31st 2020 were assessed. A cohort of PDAC patients who only had explorative laparotomy due to non-resectable tumors were also included (EXP group). Survival analysis between groups were performed with cox-regression in a multivariate approach including relevant confounders. RESULTS A total of 1758 patients were assessed, including 424 (24.1%) patients who only underwent explorative surgery leaving 1334 (75.8%) patients for further assessment. Of these 158 patients (11.8%) had selective PALN removal, of whom 19 patients (12.0%) had PALN+. Survival analyses indicated that explorative surgery was associated with significantly shorter OS compared with resection and PALN + status (Hazard Ratio 2.36, p < 0.001). No difference between PALN + and PALN- status could be demonstrated in resected patients after controlling for confounders. CONCLUSION PALN + status in patients undergoing resection offer improved survival compared with EXP. PALN + should not be seen as a contraindication for curative intended resection.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive and lethal malignancy with a high rate of recurrence and a dismal 5-year survival rate. Contributing to the poor prognosis of PDAC is the lack of early detection, a complex network of signaling pathways and molecular mechanisms, a dense and desmoplastic stroma, and an immunosuppressive tumor microenvironment. A recent shift toward a neoadjuvant approach to treating PDAC has been sparked by the numerous benefits neoadjuvant therapy (NAT) has to offer compared with upfront surgery. However, certain aspects of NAT against PDAC, including the optimal regimen, the use of radiotherapy, and the selection of patients that would benefit from NAT, have yet to be fully elucidated. This review describes the major signaling pathways and molecular mechanisms involved in PDAC initiation and progression in addition to the immunosuppressive tumor microenvironment of PDAC. We then review current guidelines, ongoing research, and future research directions on the use of NAT based on randomized clinical trials and other studies. Finally, the current use of and research regarding targeted therapy for PDAC are examined. This review bridges the molecular understanding of PDAC with its clinical significance, development of novel therapies, and shifting directions in treatment paradigm.

Abstract
Aim: Chemotherapy is standard before and/or after pancreatic cancer resection, yet benefits of pre-resection chemotherapy are unclear. Real-world pre- and post-resection treatment patterns were evaluated retrospectively. Methods: Neoadjuvant (3-months pre-surgery) and adjuvant (6-months post-surgery) treatment claims from 1 January 2016 to 31 December 2019 in US adults with resectable pancreatic cancer were analyzed. Results: Of the 737 patients, 29% received no chemotherapy in either setting; 22% received chemotherapy in both settings. In the neoadjuvant and adjuvant settings, 69 and 33% of patients, respectively, received no treatment at all. FOLFIRINOX and gemcitabine monotherapy were the most common chemotherapies in the neoadjuvant and adjuvant settings, respectively. Adjuvant FOLFIRINOX increased post-2018, whereas gemcitabine-based regimens decreased. Conclusion: Several chemotherapy regimens were used in both settings. Treatment patterns differed between the two settings.

Abstract
Distal cholangiocarcinoma (dCCA) is a rare malignancy arising from the epithelial cells of the distal biliary tract and has a poor prognosis. dCCA is often clinically silent and patients commonly present with locally advanced and/or distant disease. For patients identified with early stage, resectable disease, surgical resection with negative margins remains the only curative treatment strategy available. However, despite appropriate treatment and diligent surveillance, risk of recurrence remains high with nearly 50% of patients experiencing recurrence at 5 years subsequent to surgical resection; therefore, it is prudent to continue to optimize neoadjuvant and adjuvant therapies in order to reduce the risk of recurrence and improve overall survival. In this review, we discuss the clinical presentation, workup and surgical treatment of dCCA.

Abstract
INTRODUCTION Not all patients with pancreatic adenocarcinoma (PDAC) tolerate multiagent neoadjuvant chemotherapy (NAC). We utilized institutional data and the National Cancer Database (NCDB) to investigate if time from diagnosis to NAC initiation is associated with survival. METHODS Patients who received NAC and underwent pancreatectomy at our institution (2010-2021) or within the NCDB (2010-2016) were identified. Time from diagnosis to NAC was grouped: <21, 21-35, and >35 d. Recurrence-free (RFS) and overall survival (OS) was compared. RESULTS At our institution, 122 patients received NAC before pancreatectomy (<21 d: n = 36; 21-35 d: n = 61; >35 d: n = 25). Demographics, performance status, and anatomic resectability were similar. There was no difference in RFS (13.3 versus 12.4 versus 11.9 mo) or OS (26.7 versus 25.8 versus 26.1 mo) based on NAC timing. Patients who received FOLFIRINOX had an improvement in RFS (14.4 versus 12.2 versus 6.8 mo, P = 0.05) and OS (39.2 versus 21.4 versus 17.3 mo, P = 0.01) compared to gemcitabine with nab-paclitaxel or other regimens. Within the NCDB, 6713 patients were included (<21 d: n = 2087; 21-35 d: n = 2656; >35 d: n = 1970). There was no difference in OS (21.6 versus 20.9 versus 22.2 mo). Multiagent NAC was associated with improved OS compared to single-agent (22.6 versus 18.8 mo, P < 0.001). CONCLUSIONS Delay in NAC initiation for PDAC is not associated with survival. Patient optimization could be considered with the goal of improving tolerance of multiagent chemotherapy.

Abstract
INTRODUCTION Radical antegrade modular pancreatosplenectomy (RAMPS) was developed to improve R0 resections and lymph node harvests versus distal pancreatectomy (DP) in pancreatic adenocarcinoma (PDAC); relative complication rates are understudied. METHODS Patients undergoing distal pancreas resections from 2006 to 2020 were identified from our institutional NSQIP database, grouped by resection method, and evaluated for the following outcomes: postoperative pancreatic fistula (POPF), clinically relevant POPF (crPOPF), incisional surgical site infection (iSSI), organ space SSI (osSSI), and Clavien-Dindo grade ≥ 3 (CD ≥ 3) complications using logistic regression. Patients were matched 1:1 based on disease risk score. RESULTS Two-hundred-thirty-six and 117 patients underwent DP and RAMPS, respectively. POPF, crPOPF, CD ≥ 3 complications, iSSI, and osSSIs occurred in 105 (30%), 43 (12%), 74 (21%), 34 (10%) and 52 (15%) patients, respectively. Disease risk score matching yielded 89 similar patients per group. On multivariable analysis, patients undergoing RAMPS were not significantly more likely to experience POPF (OR 0.69, P = 0.26), crPOPF (OR 0.41, P = 0.72), CD ≥ 3 complication (OR 0.78, P = 0.44), iSSI (OR 0.58, P = 0.27), or osSSI (OR 0.93, P = 0.86). Of patients with PDAC (n = 108) mean nodal harvest were 14.8 (SD 11.30) and 19.4 (SD 7.19) nodes for patients undergoing DP and RAMPS, respectively (P = 0.01). Six patients (20%) undergoing DP had positive margins versus 12 (15%) undergoing RAMPS (P = 0.56). At a median follow-up of 17 months, there was no difference in locoregional recurrence-free survival (P = 0.32) or overall survival (P = 0.92) on Kaplan-Meier analysis. CONCLUSION RAMPS does not result in increased complications compared to DP and routine use is encouraged in pancreatic malignancies.

Abstract
BACKGROUND Return to Intended Oncologic Treatment (RIOT) has been proposed as a quality metric in the care of cancer patients. We sought to define factors associated with inability to RIOT in Pancreatic Ductal Adenocarcinoma (PDAC) patients. METHODS The NCDB was queried for patients who underwent pancreaticoduodenectomy for pathologic stage IB, IIA, or IIB PDAC from 2010 to 2016. Multivariable binary logistic regression models identified factors associated with failure to RIOT, and Kaplan-Meier survival analysis and Cox multivariable regression models demonstrated the impact of failure to RIOT on survival. RESULTS Increasing age (p < .001), Hispanic race (p = .002), pathological stage IB (p = .004) and IIA (p = .001) as compared to IIB, increasing hospital stay (p < .001), and open surgical approach (p = .024) were associated with increased risk of inability to RIOT. Male sex (p < .001), Charlson-Deyo scores of 0 (p < .001) and 1 (p = .001) as compared to >2, negative surgical margins (p = .048), receiving care at academic institutions (p = .001), and increasing institutional case volume (p = .001) were associated with improved odds of RIOT. CONCLUSIONS Patient features can impact RIOT and should be considered when designing multi-modality treatment strategies.

Abstract
BACKGROUND Standard of care for resectable pancreatic cancer is a combination of surgical resection (SR) and multiagent chemotherapy (MCT). We aim to determine whether SR or MCT is associated with superior survival for patients receiving only single-modality therapy. METHODS Patients with stage I-IIb pancreatic head adenocarcinoma who received either MCT or SR were identified in the NCDB (2013-2015). Following a piecewise approach to estimating hazards over the course of follow-up, conditional overall survival (OS) at 30, 60, and 90 days after treatment initiation was estimated using landmark analyses. RESULTS 3103 patients received MCT alone (60.3%) and 2043 underwent SR alone (39.7%). SR had an OS disadvantage at 30 (HR 3.99, 95% CI 3.12-5.11) and 60 days (HR 1.85, 95% CI 1.4-2.45), but an OS advantage after 90 days (HR 0.59, 95% CI 0.55-0.64). In a landmark analysis conditioned on 90 days survival post treatment initiation, median OS was improved for SR (17.0 vs. 12.2 months, p < 0.0001); SR improved 3-year OS by 21.3% (p < 0.05), despite patients being older (median 72 vs. 67 years, p < 0.0001) with higher Charlson-Deyo comorbidity scores (≥2: 11.2 vs. 8.6%, p = 0.006). CONCLUSION For patients with resectable pancreatic cancer, SR is associated with superior long-term survival compared to MCT.

A Randomized Placebo-Controlled Phase 2 Study of Gemcitabine and Capecitabine with or without T-ChOS as Adjuvant Therapy in Patients with Resected Pancreatic Cancer (CHIPAC). Pharmaceutics 2022; 14:pharmaceutics14030509. [PMID: 35335885 PMCID: PMC8955369 DOI: 10.3390/pharmaceutics14030509] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 02/17/2022] [Accepted: 02/23/2022] [Indexed: 02/07/2023] Open
Abstract
The antitumor activity of chitooligosaccharides has been suggested. This phase 2 trial evaluated the efficacy and safety of T-ChOS™, in addition to adjuvant chemotherapy, in patients after resection of pancreatic ductal adenocarcinoma (PDAC). In this single-center, randomized, double-blind, placebo-controlled trial using patients ≥18 years of age after complete macroscopic resection for PDAC, patients were randomly assigned (1:1) to either a continuous oral T-ChOS group or a placebo group, in combination with gemcitabine (GEM) and oral capecitabine (CAP), for a maximum of six cycles. The primary endpoint was disease-free survival (DFS). Recruitment was stopped prematurely in July 2018, with 21 of planned 180 patients included, due to poor accrual and because modified FOLFIRINOX replaced GEM/CAP for the target population. Nine patients received T-ChOS and twelve received the placebo. The median DFS was 10.8 months (95% CI 5.9–15.7) for the T-ChOS arm and 8.4 months (95% CI 0–21.5) in the placebo arm. Overall, seven patients (78%) in the T-ChOS arm and eight patients (67%) in the placebo arm experienced at least one grade 3–4 treatment-related adverse event, most frequently neutropenia. Altogether, the addition of T-ChOS to chemotherapy in patients after resection of PDAC seems safe. However, the clinical benefit cannot be assessed due to the premature cessation of the trial.

Preoperative serum carbohydrate antigen 19-9 levels predict early recurrence after the resection of early-stage pancreatic ductal adenocarcinoma. World J Gastrointest Surg 2021; 13:1423-1435. [PMID: 34950431 PMCID: PMC8649558 DOI: 10.4240/wjgs.v13.i11.1423] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 06/28/2021] [Accepted: 08/23/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a serious disease with a poor prognosis. Only a minority of patients undergo surgery due to the advanced stage of the disease, and patients with early-stage disease, who are expected to have a better prognosis, often experience recurrence. Thus, it is important to identify the risk factors for early recurrence and to develop an adequate treatment plan.
AIM To evaluate the predictive factors associated with the early recurrence of early-stage PDAC.
METHODS This study enrolled 407 patients with stage I PDAC undergoing upfront surgical resection between January 2000 and April 2016. Early recurrence was defined as a diagnosis of recurrence within 6 mo of surgery. The optimal cutoff values were determined by receiver operating characteristic (ROC) analyses. Univariate and multivariate analyses were performed to identify the risk factors for early recurrence.
RESULTS Of the 407 patients, 98 patients (24.1%) experienced early disease recurrence: 26 (26.5%) local and 72 (73.5%) distant sites. In total, 253 (62.2%) patients received adjuvant chemotherapy. On ROC curve analysis, the optimal cutoff values for early recurrence were 70 U/mL and 2.85 cm for carbohydrate antigen 19-9 (CA 19-9) levels and tumor size, respectively. Of the 181 patients with CA 19-9 level > 70 U/mL, 59 (32.6%) had early recurrence, compared to 39 (17.4%) of 226 patients with CA 19-9 level ≤ 70 U/mL (P < 0.001). Multivariate analysis revealed that CA 19-9 level > 70 U/mL (P = 0.006), tumor size > 2.85 cm (P = 0.004), poor differentiation (P = 0.008), and non-adjuvant chemotherapy (P = 0.025) were significant risk factors for early recurrence in early-stage PDAC.
CONCLUSION Elevated CA 19-9 level (cutoff value > 70 U/mL) can be a reliable predictive factor for early recurrence in early-stage PDAC. As adjuvant chemotherapy can prevent early recurrence, it should be recommended for patients susceptible to early recurrence.

Distinct Survival Outcomes in Subgroups of Stage III Pancreatic Cancer Patients: Taiwan Cancer Registry and Surveillance, Epidemiology and End Results registry. Ann Surg Oncol 2021; 29:1608-1615.

Abstract
Purpose Pancreatic cancer is one of the most malignant cancers with poor survival. The latest edition of the American Joint Committee on Cancer (AJCC) staging system classifies the majority of operable pancreatic cancer patients as stage-III, while dramatic heterogeneity is observed among these patients. Therefore, subgrouping is required to accurately predict their prognosis and define a treatment plan. This study conducts a cohort study to provide a more precise classification system for stage-III pancreatic cancer patients by utilizing clinical variables. Methods We analyzed survival using log-rank tests, univariate Cox-regression models, and Kaplan-Meier survival curves for stage-III pancreatic ductal adenocarcinoma (PDAC) patients from the Taiwan Cancer Registry (TCR). Patients were further divided into subgroups using classification and regression tree (CART) algorithm. All results were validated using the SEER database. Results Among stage-III PDAC patients, lymph node and tumor grade showed significant association with survival. Patients with N2 stage had higher mortality risks (hazard ratio [HR] = 2.30, 95% confidence interval [CI] 1.71–3.08, p < 0.0001) than N0 patients. Patients with grade 3 also had higher risk of mortality (HR = 3.80, 95% CI 2.25–6.39, p < 0.0001) than grade 1 patients. The CART algorithm stratified stage-III patients into four subgroups with significantly different survival rates. The median survival of the four subgroups was 23.5, 18.4, 14.5, and 9.0 months, respectively (p < 0.0001). Similar results were observed with SEER data.
Conclusions Lymph node involvement and tumor grade are predictive factors for survival in stage-III PDAC patients. This new precise classification system can be used to guide treatment planning in advanced-stage pancreatic cancer.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PDAC) is highly lethal. Surgery offers the only chance of cure, but 5-year overall survival (OS) after surgical resection and adjuvant therapy remains dismal. Adjuvant trials were mostly conducted in the West enrolling fit patients. Applicability to a general population, especially Asia has not been described adequately. AIM We aimed to evaluate the clinical outcomes, prognostic factors of survival, pattern, and timing of recurrence after curative resection in an Asian institution. METHODS AND RESULTS The clinicopathologic and survival outcomes of 165 PDAC patients who underwent curative resection between 1998 and 2013 were reviewed retrospectively. Median age at surgery was 62.0 years. 55.2% were male, and 73.3% had tumors involving the head of pancreas. The median OS of the entire cohort was 19.7 months. Median OS of patients who received adjuvant chemotherapy was 23.8 months. Negative predictors of survival include lymph node ratio (LNR) of >0.3 (HR = 3.36, P = .001), tumor site involving the body or tail of pancreas (HR = 1.59, P = .046), presence of perineural invasion (PNI) (HR = 2.36, P = .018) and poorly differentiated/undifferentiated tumor grade (HR = 1.86, P = .058). The median time to recurrence was 8.87 months, with 66.1% and 81.2% of patients developing recurrence at 12 months and 24 months respectively. The most common site of recurrence was the liver. CONCLUSION The survival of Asian patients with resected PDAC who received adjuvant chemotherapy is comparable to reported randomized trials. Clinical characteristics seem similar to Western patients. Hence, geographical locations may not be a necessary stratification factor in RCTs. Conversely, lymph node ratio and status of PNI ought to be incorporated.

[PMID: 34154596 PMCID: PMC8218408 DOI: 10.1186/s12957-021-02291-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Accepted: 06/04/2021] [Indexed: 12/20/2022] Open
Abstract
Background The prognosis of pancreatic cancer (PC) is extremely poor, and most patients with metastatic PC still receive palliative care. Here, we report the efficacy and safety of FOLFIRINOX (oxaliplatin, irinotecan, leucovorin, 5-fluorouracil) in the treatment of metastatic PC. Methods We searched PubMed, Web of Science, EBSCO, and Cochrane library databases for articles that described efficacy and safety of FOLFIRINOX in patients with metastatic PC, from January 1996 to July 2020. The primary outcomes targeted included overall survival (OS) and progression-free survival (PFS). Results We found that FOLFIRINOX could directly improve OS rate of patients with metastatic PC (HR 0.76, 95% Cl 0.67–0.86, p<0.001) but had no benefit on PFS. Results from subgroup analyses showed that FOLFIRINOX had superior benefits than monochemotherapy (HR 0.59, 95% Cl 0.52–0.67, p<0.001), followed by FOLFIRINOX versus combination chemotherapy (HR 0.76, 95% Cl 0.61–0.95, p<0.001). The result of FOLFIRINOX versus nab-paclitaxel + gemcitabine had no benefit (HR 0.91, 95% Cl 0.82–1.02, p>0.05). The main adverse events (AEs) targeted hematological toxicity and the gastrointestinal system, and included febrile neutropenia, a reduction in white blood cells and appetite, as well as diarrhea. Conclusion These findings indicated that FOLFIRINOX has potential benefits for the prognosis of patients with metastatic PC. Furthermore, there is no difference between the regimen of FOLFIRINOX and nab-paclitaxel + gemcitabine in this study. The application of FOLFIRINOX should be according to the actual situation of the patients and the experience of the doctors. Graphical abstract ![]()

Abstract
BACKGROUND Effect of neoadjuvant chemotherapy (NAC) for pancreatic ductal adenocarcinoma (PDAC) has remained under investigation. We investigated its effect from a unique perspective and discussed its application. PATIENTS AND METHODS We retrospecively analyzed consecutive 131 PDAC patients who underwent pancreatoduodenectomy and distal pancreatectomy. Clinicopathologic data at surgery and postoperative prognosis were compared between patients who underwent upfront surgery (UFS) (n = 64) and those who received NAC (n = 67), of which 62 (92.5%) received gemcitabine plus S-1 (GS). The GS regimen resulted in about 15% of partial response and 85% of stable disease in a previous study which analyzed a subset of this study subjects. RESULTS Tumor size was marginally smaller, degree of nodal metastasis and rate of distant metastasis were significantly lower, and pathologic stage was significantly lower in the NAC group than in the UFS group. In contrast, significant differences were not observed in histopathologic features such as vessel and perineural invasions and differentiation grade. Notably, disease-free and overall survivals were similar between the two groups adjusted for the pathologic stage, suggesting that effects of NAC, including macroscopically undetectable ones such as control of micro-metastasis and devitalizing tumor cells, may not be remarkable in the majority of PDAC, at least with respect to the GS regimen. CONCLUSIONS NAC may be useful in downstaging and improving prognosis in a small subset of tumors. However, postoperative prognosis may be determined at the pathologic stage of resected specimen with or without NAC. Therefore, NAC may be applicable to borderline resectable and locally advanced PDAC for enabling surgical resection, but UFS would be desirable for primary resectable PDAC.

Facility volume-survival relationship in patients with early-stage pancreatic adenocarcinoma treated with neoadjuvant chemotherapy followed by pancreatoduodenectomy. Surgery 2021; 170:207-214. [PMID: 33454134 DOI: 10.1016/j.surg.2020.12.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 11/29/2020] [Accepted: 12/07/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND There is evidence that neoadjuvant therapy is associated with improved survival compared with upfront pancreatectomy for pancreatic adenocarcinoma. Treatment at high-volume pancreatic surgery centers is associated with improved short-term postoperative outcomes compared with low-volume centers. We compared overall survival of patients with early-stage pancreatic adenocarcinoma who received neoadjuvant therapy before resection stratified by facility volume. METHODS Patients with clinical T0 to T2 pancreatic adenocarcinoma who received neoadjuvant therapy before pancreatoduodenectomy were identified in the National Cancer Database (2010-2016). High-volume pancreatic surgery centers performed ≥36 pancreatectomies/year. Patients were matched 1:1 by propensity score. Pathologic outcomes, postoperative outcomes, and overall survival were compared. RESULTS Before matching, 1,449 patients were treated at low-volume centers and 250 at high-volume pancreatic surgery centers. After matching, there were 177 patients per group. High-volume pancreatic surgery centers were more commonly academic/research facilities (99.4% vs 54.0%; P < .001), and patients traveled greater distances (65 vs 13 miles; P < .001). Time from diagnosis to neoadjuvant therapy and surgery was similar. Treatment at high-volume pancreatic surgery centers was associated with shorter duration of stay (7 vs 8 days; P = .003) and lower 90-day mortality rate after pancreatoduodenectomy (0.0% vs 5.0%; P = .01). Patients treated at high-volume pancreatic surgery centers had improved overall survival (36.3 vs 29.4 months; P = .03; hazard ratio 0.73). On subset analysis of academic/research facilities, high-volume pancreatic surgery centers remained associated with shorter duration of stay, lower 90-day mortality, and greater overall survival. CONCLUSION The majority of patients treated with neoadjuvant therapy for early-stage pancreatic adenocarcinoma received care at low-volume centers. Treatment at high-volume pancreatic surgery centers was associated with improved overall survival and short-term postoperative outcomes.

Cancer Manag Res 2021; 13:147-161. [PMID: 33469359 PMCID: PMC7810590 DOI: 10.2147/cmar.s285361] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 11/25/2020] [Indexed: 12/24/2022] Open
Abstract
Background The duration and the optimal time to adjuvant chemotherapy (TAC) in locally advanced gastric cancer (LAGC) have net not been sufficiently demonstrated. Sequential adjuvant chemotherapy (AC) after neoadjuvant chemotherapy plus gastrectomy is increasingly utilized, making the question more complicated. Patients and Methods Data were collected from patients with LAGC who underwent 5-Fu-based doublet regimens as adjuvant treatment after gastrectomy in a single-center database. TAC and duration (cycles) were used to evaluate survival outcomes. Results A total of 816 patients were included. Patients received over six cycles and TAC less than 42 days significantly correlated with better survival (log-rank Ptrend<0.001). The analysis of TAC and number cycles were separately applied in perioperative chemotherapy (PEC) and postoperative chemotherapy (POC) group using Cox regression. The number of cycles revealed a statistical significance improving OS rate both in POC (HR=0.904, 95% CI=0.836–0.977, P=0.011) and PEC (HR=0.887, 95% CI=0.798–0.986, P=0.026), while only in POC did the TAC show an increasing trend of risk with borderline significance (OS: HR=1.008, 95% CI=0.999–1.018, P=0.094; PFS: HR=1.009, 95% CI=1.000–1.018, P=0.055). A spline model demonstrates the less improvement in survival after cycles of chemotherapy reaching six. Conclusion Our findings suggest that TAC is more likely to downregulate the survival benefit in POC rather than PEC, while overall survival is susceptible to cumulative cycles of chemotherapy in both groups. Furthermore, six cycles of chemotherapy tended to reach the maximum survival benefits. Prospective confirmation is required.

The importance of multimodal therapy in the management of nonmetastatic adenosquamous carcinoma of the pancreas: Analysis of treatment sequence and strategy. Surgery 2020; 169:1102-1109. [PMID: 33376004 DOI: 10.1016/j.surg.2020.11.026] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 11/07/2020] [Accepted: 11/18/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Adenosquamous carcinoma of the pancreas has historically poor survival. We analyzed survival outcomes stratified by treatment regimen and sequence using an administrative dataset. METHODS Adult patients with nonmetastatic adenosquamous carcinoma of the pancreas were identified using the National Cancer Database (2010-2016). Multivariable analyses were used to determine factors associated with receipt of neoadjuvant or adjuvant chemotherapy. Overall survival was estimated by Kaplan-Meier analysis and a multivariable Cox model was used to evaluate factors associated with survival. RESULTS A total of 838 patients with adenosquamous carcinoma of the pancreas were included in the analysis. The median age was 69 years and 64.7% of patients underwent pancreatectomy. Among patients who underwent pancreatectomy, 60.5% received adjuvant chemotherapy, 14.8% received neoadjuvant chemotherapy, and 24.7% underwent surgery alone. Older age and increasing comorbidity index were associated with a reduced likelihood of receiving neoadjuvant or adjuvant chemotherapy. Median survival of patients who received chemotherapy alone was similar compared with patients who underwent pancreatectomy alone (9.2 vs 7.2 months, P = .504). Survival was improved if patients received both chemotherapy and pancreatectomy (neoadjuvant = 19.6 months, hazard ratio = 0.58; adjuvant = 19.4 months, hazard ratio = 0.64) compared with pancreatectomy alone. CONCLUSION Patients with adenosquamous carcinoma of the pancreas who do not receive multimodal therapy have poor survival. The sequence of chemotherapy and pancreatectomy is not associated with survival, but 25% of patients who undergo surgery do not receive chemotherapy. Given that there is no difference in median survival between patients who undergo pancreatectomy alone or receive chemotherapy alone, our data question whether neoadjuvant chemotherapy should be considered in patients with potentially resectable adenosquamous carcinoma of the pancreas.

Abstract
BACKGROUND Neoadjuvant therapy is increasingly utilized in the management of pancreatic adenocarcinoma. The type of neoadjuvant therapy and its effect on pathologic response remains understudied. METHODS A retrospective review was performed on patients who underwent neoadjuvant therapy followed by pancreatectomy. Multivariable regressions were used to determine associations between neoadjuvant therapy regimens and pathologic response. RESULTS Seventy-five patients with pathologic responses available for review received FOLFIRINOX (61%) or gemcitabine with nab-paclitaxel (39%). Demographics, histologic differentiation, and utilization of chemoradiation were similar between the groups. Multivariable logistic regression demonstrated that chemoradiation was associated with an increased likelihood of a complete or near-complete pathologic response and a decreased rate of lymphovascular invasion and lymph node positivity. Neither chemotherapy regimen nor number of cycles administered were associated with pathologic response. CONCLUSIONS Neoadjuvant chemoradiation may be associated with complete or near-complete pathologic response regardless of chemotherapy regimen in pancreatic cancer patients.

The experience of the minimally invasive (MI) fellowship-trained (FT) hepatic-pancreatic and biliary (HPB) surgeon: could the outcome of MI pancreatoduodenectomy for peri-ampullary tumors be better than open? Surg Endosc 2020; 35:5256-5267. [PMID: 33146810 DOI: 10.1007/s00464-020-08118-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 10/21/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND Although early series focused on benign disease, minimally invasive pancreatoduodenectomy (MIPD) might be particularly suited for malignancy. Unlike their predecessors, fellowship-trained (FT) Hepatic-Pancreatic and Biliary (HPB) surgeons usually have equal skills in approaching peri-ampullary tumors (PT) either openly or via minimally invasive (MI) techniques. METHOD We retrospectively reviewed a MI-HPB-FT surgeon's 10-year experience with PD. A sub-analysis of malignant PT was also done (MIPD-PT vs. OPD-PT). The primary endpoint was to assess postoperative mortality and morbidity. Secondary endpoints included operative parameters, length of hospital stay, and survival analysis. Moreover, we addressed practice pattern changes for a surgeon straight out of training with no previous experience of independent surgery. RESULTS From December 2007-February 2018, one MI-HPB-FT performed a total of 100 PDs, including 57 MIPDs and 43 open PDs (OPDs). In both groups, over 70% of PDs were undertaken for malignancy. Eight patients with borderline resectable pancreatic ductal cancer (PDC) were in the OPD-PT group (as compared to only 2 in the MIPD-PT group) (p = 0.07). Estimated mean blood loss and length of stay were less in the MIPD-PT group (345 mL and 12 days) as compared to the OPD-PT group (971 mL and 16 days), p < 0.001 and p = 0.007, respectively. However, the mean operative time was longer for the MIPD-PT (456 min) as compared to the OPD-PT (371 min), p < 0.001. Thirty and 90-day mortality was 2.6%/5.1% after MIPD-PT compared to 0%/3.2% after OPD-PT, respectively, p = 1. Overall 30-/90-day morbidity rates were similar at 41.0%/43.6% after MIPD-PT and 35.5%/41.9% after OPD-PT, respectively, p = 0.8 and 1. Complete resection (R0) rates were not statistically different, 97.4% after MIPD-PT compared to 87.0% after OPD-PT (p = 0.2). After MIPD and OPD for malignant PT, overall 1, 3 and 5-year survival rates, and median survival were 82.5%, 59.6% and 46.3% and 38 months as compared to 52.5%, 15.7% and 10.5% and 13 months, respectively (p = 0.01). In the MIDP-PT group, recurrence free survival (RFS) at 1, 3 and 5 years and median RFS were 69.1%, 41.9% and 33.5% and 26 months as compared to 50.4%, 6.3% and 6.3% and 13 months, in the OPD-PT group, respectively (p = 0.03). CONCLUSION FT HPB Surgeons who begin their practice with the ability to do both MI and OPD may preferentially approach resectable peri-ampullary tumors minimally invasively. This may result in decreased blood loss decreased length of hospital stays. Despite longer operative time, the improved visualization of MI techniques may enable superior R0 rates when compared to historical open controls. Moreover, combined with quicker initiation of adjuvant chemotherapeutic treatments, this may eventually result in improved survival.

Abstract
Predicting the prognosis of pancreatic cancer is important because of the very low survival rates of patients with this particular cancer. Although several studies have used microRNA and gene expression profiles and clinical data, as well as images of tissues and cells, to predict cancer survival and recurrence, the accuracies of these approaches in the prediction of high-risk pancreatic adenocarcinoma (PAAD) still need to be improved. Accordingly, in this study, we proposed two biological features based on multi-omics datasets to predict survival and recurrence among patients with PAAD. First, the clonal expansion of cancer cells with somatic mutations was used to predict prognosis. Using whole-exome sequencing data from 134 patients with PAAD from The Cancer Genome Atlas (TCGA), we found five candidate genes that were mutated in the early stages of tumorigenesis with high cellular prevalence (CP). CDKN2A, TP53, TTN, KCNJ18, and KRAS had the highest CP values among the patients with PAAD, and survival and recurrence rates were significantly different between the patients harboring mutations in these candidate genes and those harboring mutations in other genes (p = 2.39E-03, p = 8.47E-04, respectively). Second, we generated an autoencoder to integrate the RNA sequencing, microRNA sequencing, and DNA methylation data from 134 patients with PAAD from TCGA. The autoencoder robustly reduced the dimensions of these multi-omics data, and the K-means clustering method was then used to cluster the patients into two subgroups. The subgroups of patients had significant differences in survival and recurrence (p = 1.41E-03, p = 4.43E-04, respectively). Finally, we developed a prediction model for prognosis using these two biological features and clinical data. When support vector machines, random forest, logistic regression, and L2 regularized logistic regression were used as prediction models, logistic regression analysis generally revealed the best performance for both disease-free survival (DFS) and overall survival (OS) (accuracy [ACC] = 0.762 and area under the curve [AUC] = 0.795 for DFS; ACC = 0.776 and AUC = 0.769 for OS). Thus, we could classify patients with a high probability of recurrence and at a high risk of poor outcomes. Our study provides insights into new personalized therapies on the basis of mutation status and multi-omics data.

Abstract
BACKGROUND The risk factors for surgical site infection (SSI) after HPB surgery are poorly defined. This meta-analysis aimed to quantify the SSI rates and risk factors for SSI after pancreas and liver resection. METHODS The PUBMED, MEDLINE and EMBASE databases were systematically searched using the PRISMA framework. The primary outcome measure was pooled SSI rates. The secondary outcome measure was risk factor profile determination for SSI. RESULTS The overall rate of SSI after pancreatic and liver resection was 25.1 and 10.4%, respectively (p < 0.001). 32% of pancreaticoduodenectomies developed SSI vs 23% after distal pancreatectomy (p < 0.001). The rate of incisional SSI in the pancreatic group was 9% and organ/space SSI 16.5%. Biliary resection during liver surgery was a risk factor for SSI (25.0 vs 15.7%, p = 0.002). After liver resection, the incisional SSI rate was 7.6% and the organ space SSI rate was 10.2%. Pancreas-specific SSI risk factors were pre-operative biliary drainage (p < 0.001), chemotherapy (p < 0.001) and radiotherapy (p = 0.007). Liver-specific SSI risk factors were smoking (p = 0.046), low albumin (p < 0.001) and significant blood loss (p < 0.001). The rate of organ/space SSI in patients with POPF was 47.7% and in patients without POPF 7.3% (p < 0.001). Organ/space SSI rate was 43% in patients with bile leak and 10% in those without (p < 0.001). CONCLUSIONS The risk factors for SSI following pancreatic and liver resections are distinct from each other, with higher SSI rates after pancreatic resection. Pancreaticoduodenectomy has increased risk of SSI compared to distal pancreatectomy. Similarly, biliary resections during liver surgery increase the rates of SSI.

Abstract
Purpose: Adjuvant chemotherapy following resection is recommended by clinical practice guidelines for all patients with pancreatic ductal adenocarcinoma (PDAC). This study aimed to evaluate the efficacy of adjuvant chemotherapy among the staging groups of the American Joint Committee on Cancer (AJCC) for PDAC. Patients and Methods: This retrospective cohort analysis was performed by the Surveillance Epidemiology and End Results (SEER) (2004–2015) database and multi-institutional dataset (2010–2018). Baseline clinicopathologic characteristics of PDAC patients, including age, gender, ethnicity, marital status, education level, county income level, county unemployed rate, insurance status, grade, stage, chemotherapy, and radiotherapy, were collected. Overall survival (OS) was analyzed using the Kaplan–Meier method. The SEER and multi-institutional data were adjusted with 1:1 ratio propensity score matching (PSM). Results: In total, 6,274 and 1,361 PDAC patients were included from the SEER database and multi-institutional dataset, respectively. Regardless of the count of resected lymph nodes, adjuvant chemotherapy prolonged the long-term OS time for stage IB, IIA, IIB, and III patients in both SEER and multi-institutional cohorts. Nevertheless, adjuvant chemotherapy did not provide additional clinical benefits even after a PSM adjustment for stage IA patients in both SEER and multi-institutional cohorts. Conclusion: Adjuvant chemotherapy improved the long-term survival of stage IB, IIA, IIB, and III PDAC patients; however, it demonstrated no survival benefit in stage IA PDAC patients. Thus, adjuvant chemotherapy should not be recommended for stage IA PDAC patients. These would significantly reduce the economic burden of society and improve the life quality of stage IA PDAC patients.
