T1 Stage

Introduction: Studies on neoadjuvant treatment have been actively conducted in patients with resectable pancreatic cancer. However, neoadjuvant treatment effectiveness, especially in clinical T1 stage patients, still needs to be determined. We comparatively evaluated the oncologic benefit of preoperative neoadjuvant treatment in clinical T1 stage pancreatic cancer. Methods: Data from two centers were included in the comparative analysis, with overall and recurrence-free survival as primary outcomes, between January 2010 and December 2017. Results: In total, 45 patients were retrospectively reviewed in this study. Two patients in the neoadjuvant group were excluded because of distant metastasis during neoadjuvant treatment. Finally, 43 patients underwent a pancreatectomy for clinical T1 pancreatic cancer, of whom, 35 and 8 patients underwent upfront surgery and neoadjuvant treatment, respectively. Overall survival was similar in the two study groups (5-year overall survival rate: neoadjuvant group, 75%; upfront surgery group, 43.9%, p = 0.066). Conclusions: In our study on patients with clinical T1 stage pancreatic cancer, no significant differences were reported in the oncological outcome in the neoadjuvant therapy group. Large-scale prospective studies are needed to determine the survival benefits of neoadjuvant treatment for early-stage pancreatic cancer.

314 Background: Resectable pancreatic cancer patients often present with obstructive jaundice necessitating the placement of biliary stents or percutaneouse drainage catheters. We sought to evaluate whether preoperative biliary drainage affects recurrence and survival. Methods: An IRB-approved study was conducted on our institutional tumor registry to identify pancreatic cancer patients who were treated with upfront surgery between 2000 and 2012. Patients were then stratified by preoperative use of endoscopically placed stents (ERCP), percutaneous catheters (PTC), or no biliary drainage (NBD). The primary endpoint was overall survival (OS). Survival curves were calculated using the Kaplan-Meier method and the log-rank test. Multivariate analysis (MVA) was performed with a Cox regression model. Results: We identified 202 patients for the study (21 PTC; 89 ERCP; 92 NBD). Key differences between the 3 groups were mean pathologic tumor size (p=0.005), pathologic T3/4 (p =0.01), and pathologic N1 (p=0.007) status, with more aggressive pathologic features in PTC patients. PTC patients had a non-significant increase in rate of hepatic recurrences compared with ERCP and NBD patients (47.4% vs. 26.6% vs. 28.7%, respectively; p=0.20). PTC patients also had worse median and 3 year survival (21 months and 16%) compared to ERCP (23.3 months and 39%) and NBD patients (29 months and 45%, p=0.02). MVA revealed that PTC was an independent predictor of worse overall survival (HR 2.3[95% CI 1.3-4.0], p=0.005), along with pathologic tumor size (HR 1.1[1.0-1.3], p=0.008), nodes positive (HR 1.1[1.1-1.2], p=0.001), and post-operative CA19-9 >90 (HR 2.6[1.5-4.4], p=0.001). Conclusions: Patients with resectable pancreatic cancer who require a pre-operative PTC drain had a non-significant increase in hepatic recurrence rate and worse overall survival than patients who either had an ERCP stent placed or no biliary decompression prior to surgery. Given their worse prognosis, patients who require PTC placement might also benefit from neoadjuvant treatment with restaging prior to surgery.

402 Background: The aim of this retrospective study was to evaluate the efficacy of adjuvant hepatic arterial infusion chemotherapy (HAI) using high-dose 5-fluorouracil with systemic gemcitabine on prognosis of resected pancreatic cancer. Methods: Between January 2006 and April 2016, 298 patients underwent elective pancreatic resection for resectable or borderline resectable pancreatic cancer at Nara Medical University Hospital. Patients who received adjuvant HAI plus systemic gemcitabine after surgery (HAI group) were compared with those who received systemic chemotherapy alone (control group). Patients were propensity score matched for age, sex, ASA score, CA19-9, NCCN resectability status, neoadjuvant treatment, surgical procedure, portal vein invasion, T stage, N stage, and margin status. Results: 224 patients with resectable or borderline resectable pancreatic cancer were enrolled in this study. 151 patients in the HAI group and 73 patients in the control group were included. Propensity score matching analysis was used to identify 63 well-balanced patients in each group for overall survival comparison. The estimate overall survival (OS) for patients treated with HAI was longer than patients without HAI in both the whole cohort (median OS, 54 vs. 24 months, respectively; P < 0.001) or matched cohort (median OS, 58 vs. 26 months, respectively; P = 0.003). The liver was only recurrence site in which significant decrease was observed in the HAI group compared to the control group ( P = 0.031). In the multivariate analysis, adjuvant chemotherapy without HAI were independently associated with worse outcome in the whole cohort. A total of 127 patients in the HAI group (84%) had completed the planned dose of HAI. The remaining 24 patients stopped treatment before the end of the planned cycle due to catheter-associated complications in 9 (6.0%) and development of liver abscess in 2 (1.3%). No treatment-related deaths occurred. Conclusions: The efficacy of hepatic arterial chemoinfusion as adjuvant treatment for resectable pancreatic cancer should be revisited.

Number Of Patients

Pancreatic cancer is the third leading cause of cancer-related mortality in the US. Outcomes for patients with pancreatic cancer are poor as curative approaches are only available to the minority of patients who have localized tumors for which surgery may be an option. The past decade has established fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) as the new standard of care following resection for fit patients with resectable pancreatic tumors. However, most patients will relapse and a large number of patients treated with upfront resection are unable to receive or complete adjuvant chemotherapy. There is therefore considerable interest in neoadjuvant treatment strategies for patients with resectable and borderline resectable pancreatic cancer as a way to provide early systemic treatment of micrometastatic disease, facilitate lymph node downstaging, and increase the likelihood of negative resection margins (R0). This review will focus on key aspects of completed trials evaluating adjuvant therapy in resectable pancreatic cancer and will provide an overview of emerging evidence supporting the use of neoadjuvant treatment strategies for both resectable and borderline resectable pancreatic cancer.

Biological Variables

e15712 Background: Accurate selection of patients based on radiological and biological variables is crucial to avoid over treatment and unnecessary R1 resection in pancreatic cancer (PC). Methods: We retrospectively investigated 73 patients diagnosed with PC treated between January 1998 to October 2015. We applied NCCN definitions for Resectable (RD), borderline resectable (BRD) and unresectable disease(URD). Logistic regression was used to identify significant indicators of R0 resection. Odds ratios were used to compare differences of overall survivability by R0 and No surgery. Fisher’s Exact Test was used for significance on all tabulated data. Wilcoxon Rank-Sum was used for the comparison of two medians and Kruskal-Wallis to compare more than two medians, and log-rank test was used to compare Kaplan-Meyer Curves. Results: Radiologically RD comprised 21% (15/73) of total cases, 80% (12/15) of these underwent R0 resection. URD comprised 79% (58/73). Patients presenting with abdominal pain were 2.5 times (Odds Ratio; p = 0.0275) more likely to be URD. The mean tumor size for R0 resectability was 2.28 cm (n = 12). The median CA 19-9 for URD was 1473 vs 162 for RD (p = 0.0124). Stage at presentation and resectability were statistically associated. (p = 0.0002): 100% of Stage 1 (n = 4) and, 27% of Stage 2, (11/41) were resectable. Twenty-three cases were identified as BRD, 21/23 received neoadjuvant chemotherapy, 47.83% had radiological PR, 28.26% had SD and 23.91% PD. There was no association between type of Neoadjuvant treatment (Chemo XRT vs Chemotherapy) and radiological response (p = 0.8798). None of the 21 BRD patients underwent surgery. Median Overall Survival for R0 resection was 22.3 months (95% CI 15.23, 36.50) vs. 5.1 who did not have surgery (95% CI 3.55, 7.57) (p = 0.0010). Conclusions: Nearly 80% patients identified as resectable on imaging underwent R0 resection. Although there were partial responses seen in BRD patients that underwent neoadjuvant treatment eventually none underwent R0 resection. Patients presenting with abdominal pain and high CA19-9 ( > 1400 U/ml) are likely to URD. Early stage and R0 resection were associated with positive outcomes.

Pancreatic ductal adenocarcinoma (PDAC) presents many challenges in the clinic and there are many areas for improvement in diagnostics and patient management. The five-year survival rate is around 7.2% as the majority of patients present with advanced disease at diagnosis that is treatment resistant. Approximately 10–15% of PDAC cases have a hereditary basis or Familial Pancreatic Cancer (FPC). Here we demonstrate the use of circulating free DNA (cfDNA) in plasma as a prognostic biomarker in PDAC. The levels of cfDNA correlated with disease status, disease stage, and overall survival. Furthermore, we show for the first time via BEAMing that the majority of hereditary or familial PDAC cases (around 84%) are negative for a KRAS somatic mutation. In addition, KRAS mutation negative cases harbor somatic mutations in potentially druggable genes such as KIT, PDGFR, MET, BRAF, and PIK3CA that could be exploited in the clinic. Finally, familial or hereditary cases have a longer overall survival compared to sporadic cases (10.2 vs. 21.7 months, respectively). Currently, all patients are treated the same in the clinic with cytotoxic agents, although here we demonstrate that there are different subtypes of tumors at the genetic level that could pave the way to personalized treatment.

Aim. To establish the association between pancreatic cancer precursor lesions and chronic opisthorchiasis. Materials and methods. A single center case-control study was conducted at a low-volume pancreatic surgery center in Khanty-Mansiysk. We retrospectively collected morphological data from 47 pancreatoduodenectomies performed for pancreatic ductal adenocarcinoma. The study group included 23 cases of pancreatic ductal adenocarcinoma with concomitant chronic Opisthorchis felineus invasion which were compared to 24 controls consisting of “pure” cancer. Qualitative analysis was performed using χ2 Pearson criterion. Exact Fisher test was used for small samples. Time to progression and overall survival rates were calculated using Kaplan-Meier survival analysis. Data were collected and analyzed in Statistica 7.0. Results. PanINs were seen in 41,7% pancreata resected for ductal adenocarcinoma of the head and in 95,7% cases of pancreatic cancer in background of chronic opisthorchiasis (р = 0,000; 95% CI 3,5-268). PanIN high grade were observed only in opisthorchiasis group. In mixed pathology invasive cancer component tended to be more dedifferentiated and advanced when compared to pure cancer group (p = 0,029). Median disease free survival was 9 mo. in both groups and overall survival was 13 mo. in non-opisthorchiasis group and 15,3 mo. in opisthorchiasis group (р = 0,437). Conclusion. Chronic opisthorchiasis is associated with pancreatic intraepithelial neoplasia. Pancreatic ductal adenocarcinoma in background of opisthorchiasis with preneoplastic lesions tend to be more advanced in stage and poorly differentiated. Disease free and overall survival have no statistically significant differences in patients with and without Opisthorchis felineus invasion.

Abstract BackgroundAccording to the NAPOLI-1 trial, nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) showed improved overall survival compared to fluorouracil alone for patients with metastatic pancreatic cancer who previously treated gemcitabine-based therapy. In that trial, Asian patients had frequent dose modification due to hematological toxicity. There has been limited information on the clinical benefit and toxicity of this regimen in a real-world setting. Herein, we assessed real-world experience of nal-IRI plus 5-FU/LV in patients with advanced pancreatic cancer after gemcitabine failure.MethodsWe conducted a single institution retrospective analysis of response, survival and safety in patients who had been treated with nal-IRI with 5-FU/LV. Patients with metastatic pancreatic ductal adenocarcinoma previously treated with gemcitabine-based therapy received nal-IRI (80mg/m2) with 5-FU/LV every 2 weeks. ResultsFifty-one patients received nal-IRI plus 5-FU/LV between January 2015 and December 2020. The median age was 67 years, and males were 58.8%. A total of 40 (78.4%) and 11 (21.6%) patients had received one and two lines of prior chemotherapy before enrollment, respectively. Median progression-free survival was 2.8 months (95% confidence interval [CI] 1.8-3.7) and median overall survival was 7.0 months (95% CI 6.0-7.9). Chemotherapy doses were reduced or delayed in 33 (64.7%) patients during the first 6 weeks and median relative dose intensity was 0.87. Thirty-six (70.6%) patients experienced any grade 3 or 4 adverse events. Most common grade 3 or 4 adverse event was neutropenia (58.8%) and most non-hematologic adverse events were under grade 2. Since the start of first-line chemotherapy, median overall survival was 16.3 months (95% CI 14.1-18.4).ConclusionsNal-IRI plus 5-FU/LV seems to be effective, with manageable toxicities, after gemcitabine-based treatment in patients with metastatic pancreatic ductal adenocarcinoma.
