Locally Advanced Pancreatic Adenocarcinoma

Abstract Introduction/Objective In 2019 and 2020, the National Comprehensive Cancer Network (NCCN) advanced a recommendation that all patients with metastatic, recurrent, or locally advanced pancreatic adenocarcinoma should undergo tumor gene profiling (TGP). Prior to these recommendations, TGP in targeted patients have demonstrated a high frequency of KRAS (>90%), TP53 (60-70%), CDKN2A (>50%), SMAD4, TGF- βR1, and TGF- βR2 mutations or alterations. Even less frequent mutations such as the homologous recombination repair (HRR) genes impact treatment by predicting tumor response to platinum-based therapies. However, the literature is sparse for the frequency of these mutations in patients with pancreatic adenocarcinoma undergoing generalized testing as part of the standard of care per NCCN guidance, particularly for veterans. Methods/Case Report For a quality assurance study, a retrospective review was performed to identify patients with pancreatic adenocarcinoma at a tertiary medical center serving veterans from January 2019 to February 2021 with TGP performed as part of their care. All of the TGP had been sent to Foundation Medicine (Cambridge MA), and the identifiable tumor mutations from the test reports were recorded to document the frequency of KRAS, TP53, CDKN2A, SMAD4, TGF- βR1, TGF- βR2 and HRR mutations or alterations. Results (if a Case Study enter NA) There were a total of 11 patients with pancreatic adenocarcinoma who had a tumor specimen for TGP during the study period. All 11 patient tumors had KRAS mutation. 10 out of 11 had a mutation or alteration in TP53. 8 of 11 patients had a CDKN2A mutation or alteration. 7 of 11 patients had a mutation or alteration of SMAD4 though none had TGF- βR1 or TGF- βR2. 2 of 11 patients had HRR mutations (1 with FANCA and 1 with ATM). Conclusion Tumor mutations on generalized gene profiling per NCCN guidelines continue to identify important mutations in pancreatic adenocarcinoma for veteran patients.

Modified Folfox6

303 Background: Pancreatic adenocarcinoma has historically been as a disease with a poor prognosis with a 5 year survival rate of about 6%. The recently published ACCORD 11 trial demonstrated an improved overall survival utilizing FOLFIRINOX versus gemcitabine which has been the standard of care. However, FOLFIRINOX was associated with a significantly higher incidence of both hematologic and nonhematologic toxicities at the expense of increased toxicity. At our institution, FOLFIRINOX has been found to have a very similar toxicity profile with a significant impact on quality of life. For that reason, many patients at our institution have been treated with mFOLFOX6 with better tolerability instead of FOLFIRINOX in the palliative setting. Methods: We performed a retrospective chart review to analyze overall survival in patients withof unresectable pancreatic cancer (locally advanced and metastatic). Institutional tumor registry database was used to identify patients with unresectable pancreatic adenocarcinoma from January 2009 to March 2012. Medical records were reviewed to identify patients who were treated with at least 1 cycle of modified FOLFOX-6 as a line of treatment during their disease course. Overall survival was calculated for this cohort of patients. Results: 26 patients (15 male, 11 female) with unresectable pancreatic adenocarcinoma were identified. Mean age was 65.3 years. 19 patients had metastatic disease whereas 7 patients had locally advanced disease at diagnoses. Modified FOLFOX6 as a 1st line, 2nd line and 3rd line therapy was given in 17, 6 and 3 patients respectively. The median overall survival was 9 month while the mean survival was 10.6 months. 7 patients were treated with FOLFIRI as 2nd or 3rd line treatment. Nine patients are still alive. Conclusions: Modified FOLFOX-6 is an acceptable treatment for metastatic and locally advanced pancreatic adenocarcinoma. Even though our sample size is small, overall survival is comparable to that of FOLFIRINOX. A multi-institutional, randomized trial evaluating sequencing of mFOLFOX6 and FOLFIRI and comparing it with FOLFIRINOX would be useful.

Abstract Background: The current study aimed to evaluate the outcomes of patients with unresectable non-metastatic locally advanced pancreatic adenocarcinoma (LAPA) who did not benefit from resection considering the treatment strategy in the clinical settings. Methods: Between 2010 and 2017, a total of 234 patients underwent induction chemotherapy for LAPA that could not be treated with surgery. After oncologic restaging, continuous chemotherapy or chemoradiation (CRT) was decided for patients without metastatic disease. The Kaplan–Meier method was used to determine overall survival (OS), and the Wilcoxon test to compare survival curves. Multivariate analysis was performed using the stepwise logistic regression method. Results: FOLFIRINOX was the most common induction regimen (168 patients, 72%), with a median of 6 chemotherapy cycles and resulted in higher OS, compared to gemcitabine (19 vs. 16 months, hazard ratio (HR)=1.2, 95% confidence interval: 0.86–1.6, P =.03). However, no difference was observed after adjusting for age (≤75 years) and performance status score (0–1). At restaging, 187 patients (80%) had non-metastatic disease: CRT was administered to 126 patients (67%) while chemotherapy was continued in 61 (33%). Patients who received CRT had characteristics comparable to those who continued with chemotherapy, with similar OS. They also had longer progression-free survival (median 13.3 vs. 9.6 months, HR=1.38, 95% confidence interval: 1–1.9, P <.01) and limited short-term treatment-related toxicity. Conclusions: The median survival of patients who could not undergo surgery was 19 months. Hence, CRT should not be eliminated as a treatment option and may be useful as a part of optimised sequential chemotherapy for both local and metastatic disease.
