The Impact

318 Background: Pancreatic cancer (PC) has a poor prognostic. Only patients who undergo a complete R0 surgery have longer survival rates. Treatment of locally-advanced (LA) and borderline (BL) PC is controversial. Folfirinox is considered as a standard first-line treatment in metastatic patients. The aim of our study was to evaluate the impact of Folfirinox in LA and BL PC. Methods: We performed a retrospective analysis of prospectively-collected data from LA and BL PC patients treated with original Folfirinox in our institution between January 2010 and February 2015. Results: 35 patients were enrolled, 20(57.1%) pancreatic head adenocarcinoma, 19(54.3%) LA and 16(45.7%) BL PC, 54.3% male, median age 60 years old [44-74]. OMS was 0, 1, 2 for 21(61.8%), 11(32.4%), 2(5.9%) patients. Median CA19.9 level was 5N [1-33]. All patients had Folfirinox in first-line followed by radiochemotherapy (RTCT) in 23(65.7%) patients, with Gemzar and Xeloda in 21 and 2 patients. Median number of chemotherapy cycles was 4 [1-13]. The grade 3-4 toxicity rate was 17.1% (n = 6), mainly digestive (67%), hematologic (16.7%), none neurologic. There was no toxic death. 17(46%) patients underwent surgery, 7 LA and 10 BL, with a R0 resection in 13 patients, mainly 8 PT3 (57.1%), no PT0, and 14N+. The morbidity rate was 40%, including 3 fistulae and 2 hemorrhages. Median overall survival was 24 months (95%CI:14-44), 53 (95%CI:26-.) and 12 months (95%CI: 9-19) in surgery versus no-surgery patients (p< 0.001). Progression-free survival was 13.9 months (95%CI:11.2-17.1), 16.2 (95%CI:13.7-25.3) and 9.5 (95%CI:7.4-15.9) months in surgery versus no-surgery patients. 13 patients were still alive at the time of analysis, with a median follow-up of 44 months (95%CI:7-53). 30 patients had disease progression, locally, distant or both in 7(24.1%), 20(69.0%) and 3(13.1%) patients. Weight loss, OMS status, abdominal pain and CA199 level at diagnosis were not correlated with better survival. Conclusions: Folfirinox, followed or not by RTCT, as inductive treatment for LA and BL PC is feasible with acceptable toxicity, and allowed resectability in 37.1% patients, and thus a longer survival. Further studies are needed to confirm these encouraging results.

The Impact

e16746 Background: Ataxia telangiectasia mutated (ATM) protein is a DNA damage repair enzyme and regulates normal cell-cycle mechanisms. Germline ATM mutations are associated with increased risk for developing pancreatic cancer (PC), occurring in approximately 2% of PC patients (pts). The role of germline ATM mutations in PC is not well defined. The objective of this study was to compare survival outcomes in patients with germline ATM mutations compared to somatic ATM mutations in PC. Methods: Tumor genomic profiling was completed in 144 PC patients at a single institution in the US, where pts were included in the analysis if they had either germline ATM mutations or somatic ATM mutations. Clinical outcomes were compared between pts with germline ATM mutations and pts with somatic ATM mutations only. Adjusted Cox regression models were fit to evaluate the impact of ATM mutation on overall survival (OS), calculated from treatment (tx) initiation to death, and progression free survival (PFS) calculated from tx initiation to first progression. Results: From 144 PC pts evaluated, 7 pts (4.9%) had germline ATM mutations, all of whom presented with metastatic disease, and 14 pts (9.7%) with somatic ATM mutations only, of whom 10 presented with metastatic disease and 4 who initially presented with locally advanced PC. The majority of pts (15/21), including all 7 pts with germline ATM mutations and 8 with somatic ATM mutations, were treated with first line gemcitabine and abraxane. Median OS was not reached in patients with germline mutations, and 11 months for patients with somatic mutations. Pts with germline ATM mutations had significantly higher OS (HR: 0.12, 95% CI 0.03-0.62, p = 0.01) and PFS (HR:0.26, 95%CI 0.07-0.91, p = 0.04) compared to patients with somatic ATM mutations only after adjusting for age, sex, and first-line tx. Conclusions: Pts with germline ATM mutations may experience greater survival benefit from tx compared to those with only somatic ATM mutations. Further research into the underlying mechanism is warranted.

European Multicenter Study

Background: Gemcitabine/nab-paclitaxel (GN) and FOLFIRINOX (FFX) are two standard first-line therapies for metastatic pancreatic cancer (PC) but have rarely been compared, especially in patients with locally advanced PC (LAPC). Methods: This is a retrospective European multicenter study including patients with LAPC treated with either GN or FFX as the first-line therapy between 2010 and 2019. Coprimary objectives were progression-free survival (PFS) and overall survival (OS), both estimated using the Kaplan–Meier method. Results: A total of 147 patients (GN: n = 60; FFX: n = 87) were included. Tumor resection rates were similar between the two groups (16.7% vs. 16.1%; p = 1), with similar R0 resection rates (88.9%). Median PFS rates were not statistically different: 9 months (95% CI: 8–13.5) vs. 12.1 months (95% CI: 10.1–14.6; p = 0.8), respectively. Median OS rates were 15.7 months (95% CI: 12.6–20.2) and 16.7 months (95% CI: 14.8–20.4; p = 0.7), respectively. Abdominal pain at the baseline (HR = 2.03, p = 0.03), tumors located in the tail of the pancreas (HR = 4.35, p = 0.01), CA19-9 > 200 UI/L (HR = 2.03, p = 0.004) and tumor resection (HR = 0.37, p = 0.007) were independent prognostic factors for PFS, similarly to OS. CA19-9 ≤ 200 UI/L (OR = 2.6, p = 0.047) was predictive of the tumor response. Consolidation chemoradiotherapy, more often used in the FFX group (11.7% vs. 50.6%; p < 0.001), was not predictive. Conclusion: This retrospective study did not show any difference between GN and FFX as the first-line treatment in patients with LAPC.

The Impact

Erlotinib plus gemcitabine is one of the standard chemotherapies for unresectable pancreatic cancer. Pancreatic cancer has the highest frequency of KRAS gene mutations among human cancers, and some studies suggest that KRAS status might be a predictive biomarker for anti-epidermal growth factor receptor treatment. However, the reliability of this biomarker has not been confirmed. Here, we evaluated the impact of KRAS mutations in pancreatic cancer patients treated with first line gemcitabine-based chemotherapy. 23 patients treated with gemcitabine-based chemotherapy whose KRAS status could be examined from primary or metastatic lesions were enrolled. KRAS mutations were analyzed by sequencing codons 12 and 13. We retrospectively evaluated the correlation between KRAS status, and prognosis and treatment efficacy. Patient characteristics were as follows: median age 68 years, male/female=6/17, PS 0/1=9/14, TNM stage III/IV=1/22, and gemcitabine alone/erlotinib plus gemcitabine=13/10. Among the 23 patients, KRAS codon 12 was mutated in 15, one of whom also had mutation on codon 13. Median progression-free survival (PFS) and overall survival (OS) of all patients were 4.3 months (95% confidence interval (CI): 3.1 to 5.4) and 8.1 months (95% CI: 5.9 to 10.0; events in 96%), respectively. KRAS status showed no association with PFS (p=0.310), OS (p=0.934), or the efficacy of treatment with (p=0.833) or without erlotinib (p=0.478). Thus, in this study, there was no correlation between KRAS status and the efficacy of first line chemotherapy with gemcitabine with or without erlotinib. Identification of a rationale for personalized medicine in pancreatic cancer will require further exploratory prospective studies.

Background: New chemotherapy regimens for the treatment of metastatic pancreatic cancer have changed the therapy paradigm. We aimed to assess their impact on the treatment landscape and clinical outcome at our academic institution. Methods: In this single institutional posthoc registry analysis, we assessed characteristics and survival rates from all patients with locally advanced and metastatic pancreatic cancer who started a systemic treatment between 01/2011 and 12/2017. Survival analyses were performed by Kaplan-Meier and Cox proportional hazards model. Results: A total of 301 patients started a systemic treatment in the observation period. In the first line treatment, we observed a shift from the four different main regimens (gemcitabine/nab-paclitaxel, modified FOLFIRINOX, gemcitabine/oxaliplatin +/− erlotinib or gemcitabine alone) to gemcitabine/nab-paclitaxel and modified FOLFIRINOX that add up to more than 80% of administered first line treatments in each of the time cohorts (2011–2013 vs. 2014–2017). The rate for first line modified FOLFIRINOX treatment was balanced between the two groups (19% and 15%). Median overall survival differed significantly between the two time cohorts (8.89 versus 11.9 months, p = 0.035). Survival rates for different first to second line treatment sequences (modified FOLFIRINOX to gemcitabine/nab-paclitaxel, gemcitabine/nab-paclitaxel to fluoropyrimidines plus nanoliposomal irinotecan, or gemcitabine/nab-paclitaxel to fluoropyrimidines plus oxaliplatin) were not significantly different and median overall survival ranged from 14.27 to 15.64 months. Conclusion: Our study provides real-world evidence for the effectiveness of the new chemotherapy regimens and underscores the importance of the choice of the front-line regimen when considering different sequencing strategies.

348 Background: Advanced cholangiocarcinoma are benefiting from platinum-based therapy (Valle et al, NEJM) but no validated option is available as second line systemic therapy. Methods: Objective : Explore the effect of 2 consecutive lines of chemotherapy in patients with cholangiocarcinoma fitted to receive sequential administration of received gemcitabine and oxaliplatin (GEMOX) followed by FOLFIRI. A retrospective study was conducted among patients who received GEMOX in first line followed by FOLFIRI in second line from January 2005 and September 2013 at Beaujon hospital (France). Overall survival, progression free survival and prognostic factors were determined by the Kaplan-Meier method and univariate analysis. Results: Thirty-four patients were included in the cohort. Eighteen patients (53%) presented intrahepatic cholangiocarcinoma (ICC) and 16 (47%) presented extrahepatic cholangiocarcinoma (ECC). At diagnosis, tumors were localized in 4 patients (12%), locally advanced in 13 patients (38%) and metastatic in 17 patients (50%). Among 10 patients with prior surgery, 7 received GEMOX adjuvant chemotherapy. The median overall survival time was 20.6 months in all patients and 17.1 months in patients who received GEMOX followed by FOLFIRI in the advanced setting. The median first line progression-free survival (PFS) was 5.7 months with a median number of 8 cycles of GEMOX. The median second line PFS was 2.9 months with a median number of 5 cycles of FOLFIRI. Patients who received >8 cycles of GEMOX in first line survived longer than those who received ≤ 8 cycles (23.1 vs 15.1 months; hazard ratio (HR) 5.22, P=0.009). The PFS of second line FOLFIRI was not different in patients who received more than 8 cycles of GEMOX (HR=1.72 P=0.26). Univariate analysis showed no correlation between age, sex, localization of primary, stage, and surgery with overall survival. No severe toxicity was reported related to GEMOX-FOLFIRI sequential combination in this study. Conclusions: Sequential administration of GEMOX followed by FOLFIRI is feasible for fitted patients with cholangiocarcinomas, yielding overall survival over 1 year.

e15765 Background: Pancreatic cancer is one of the highest cancer-mortality diseases worldwide with limited treatment. Most patients had local advanced or metastatic disease at the time of diagnosis. Gemcitabine-based therapy has been standard regimen in the past few decades. It is necessary to find new strategies of treatment. Methods: The aim of this study was to evaluate the efficacy and safety of nab-paclitaxel in combination with S-1 as first-line therapy in advanced pancreatic cancer. We retrospectively evaluated 79 patients with advanced pancreatic cancer from 2014 to 2016 treated in our medical center. All the patients received at least two cycles of combination therapy. Nab-paclitaxel was administered 260mg/ m2 as a total dose on day 1 and 5 or on day 1 and 8. S-1 was administered orally twice a day for 14 days according to body surface area. S-1 monotherapy was administered as maintenance treatment after 6 to 8 cycles of combination therapy until the progression of disease. Results: In all the 79 patients enrolled, the median age was 56, range from 36 to 77, 56 (70.9%) patients had KPS 90, 58 (73.4%) patients had multiple metastatic sites. The overall response rate was 51.9%; median progression-free survival was 5.7 months (95%CI 5.010-6.292); median overall survival was 11.9 months (95%CI 9.731-13.990). The efficacy of CA19-9 decrease > 50% was significant higher compared with those of CA19-9 decrease < 50%. Treatment was well tolerated. Grade 4 toxicity was only reported in neutropenia of 5 patients. Grade 3 adverse events include neutropenia in patients (13.9%), nausea and vomiting in one patient (1.3%), peripheral sensory in one patient (1.3%) and alopecia in 3 patients (3.8%). Conclusions: Nab-paclitaxel in combination with S-1 as first-line therapy demonstrated promising antitumor activity and well-tolerated toxicities and presents a new alternative for locally advanced and metastatic pancreatic cancer.

e15744 Background: FOLFIRINOX (FFN) and Gemcitabine plus nab-paclitaxel (GN) have been established as first line chemotherapy in advanced pancreatic cancer (PC). But there is no head-to-head randomized trial data available to support preferable first line choice between these two regimens. Methods: We retrospectively evaluated 154 chemotherapy-naïve locally advanced and metastatic PC patients treated with FFN or GN at KU Cancer Center between January 2011 and November 2016. FFN consisted of Oxaliplatin 85mg/m2, Irinotecan 180mg/m2, 5-FU 400mg/m2 as a bolus and 2,400 mg/m2over 46 hour on days 1 and 15 every 4 weeks. GN consisted of Gemcitabine 1000mg/m2 plus nab-paclitaxel 125mg/m2 day1,8,15 every 4 weeks. We compared characteristics, efficacy and adverse events between FFN and GN. Results: 107 patients were treated with FFN and 47 patients with GN as first line therapy. Demographic and baseline characteristics (FFN/GN) were as follows: Median age 61/63 years, ECOG performance status (0-1): 90% / 83%, Gender (male): 57% / 54%, distant metastases: 52%/70%, biliary stenting: 41%/20%, locally advanced tumor: 48%/30%, pancreatic head tumors: 63%/55%, median number of cycles: 4/4 respectively. Objective response rate (13% vs. 10%), Stable disease rate (76% vs 82%) and disease control rate (89% vs. 92%, p = 0.5) were similar in FFN and in GN. Median PFS was 11.7 months (95% CI: 7.2-16.1) in FFN and 5.7 months (95% CI: 2.7-8.8) in GN [p = 0.07]. Median OS was 15.9 months (95% CI: 13.7-18.1) in FFN and 10.8 months (95% CI: 7.1 – 14.5) in GN [p = 0.17]. Incidences of grade 3 or higher adverse effects were neutropenia (33% vs. 17%), anemia (14% vs 31%), thrombocytopenia (28% vs 6%), elevated creatinine (2.8% vs 4%), elevated transminases (3.7% vs 6%), diarrhea (5% vs. 0%), and peripheral neuropathy (6% vs. 6%) respectively. Conclusions: Patients treated with FFN showed statistically better PFS compared to GN. However this difference in PFS did not translate into statistically significant difference in OS. Response rates were similar. Incidences of adverse events were relatively more with FFN compared to GN as expected.

e16755 Background: Only a minority of pancreatic cancer patients (pts) are surgical candidates at presentation. Neoadjuvant chemotherapy (NAT) is proposed to increase the proportion of surgical candidates. This study investigates the impact of NAT in routine care of pancreatic cancer. Three cohorts were analysed, patients with early-stage resectable (ER), borderline resectable (BR) and locally advanced (LA) pancreatic cancer. Within these groups, survival outcomes of those undergoing immediate resection (IR) was compared to those receiving NAT with nab-paclitaxel and Gemcitabine (nabPGem) and NAT with FOLFIRINOX. Methods: The PURPLE registry consists of 1492 pancreatic cancer pts from 27 hospitals in Australia, New-Zealand and Singapore, collated between 2016-2019. After exclusion of LA unresectable and metastatic pts (n = 809), 683 pts were included. Kaplan-Meir curves estimated survival between groups with 95% confidence intervals. Multivariable cox proportional hazards models adjusted for age, gender and ECOG performance status. Results: Of 683 pts, 107 received NAT and 576 underwent IR. Those in the NAT group had favourable characteristics, including younger age (mean 63 vs. 66 yrs, p < 0.01) and higher proportion of ECOG 0 vs. ≥1 (64% vs 46%) than those undergoing IR. Of those that received NAT, 64 received FOLFIRINOX and 35 nabPGem. Those receiving FOLFIRINOX were younger (mean: 60 vs. 67 yrs, p < 0.01) and were more likely ECOG 0 compared to those receiving nabPGem (72% vs. 46%, p = 0.02). Resection rates for pts undergoing IR vs. NAT were 88% vs. 50% in ER and 16% vs. 43% in BR. Rates of R0 resection margins in pts undergoing IR vs. NAT were 54% vs. 25% in ER and 6% vs. 21% in BT. Comparing ER to BR, mOS was 29.9 vs. 20.3 mths (HR: 0.54, p < 0.01). Within BR, mOS was 20.3 vs. 17.2 mths for NAT vs. IR (HR: 1.11, p = 0.74). Comparing those receiving FOLFIRINOX vs. nabPGem over all groups, mOS was 22 mths vs. 12 mths (HR: 0.31, p < 0.01). Conclusions: Real-world data confirms the use of NAT remains infrequent in this Asia-Pacific population. The use of FOLFIRINOX was associated with better survival than nabPGem based on this observational study. Improved methods for treatment selection are required. Potential biomarkers including circulating tumor DNA are being explored in the DYNAMIC-Pancreas clinical trial.

The Impact

Pancreatic cancer (PaC) induces a prothrombotic and hypercoagulable state. The aim of this study was to investigate the effect of tinzaparin in combination with chemotherapy. The PaCT (pancreatic cancer and tinzaparin) study was a retrospective observational study that collected data regarding progression free survival (PFS) in advanced or metastatic PaC patients who received thromboprophylaxis with tinzaparin during chemotherapy with nab-paclitaxel (N) and gemcitabine (G). The primary end point was to compare, from already published data, the PFS of patients receiving thromboprophylaxis with tinzaparin with the PFS of patients receiving chemotherapy with N–G but no thromboprophylaxis. Secondary end points were efficacy and safety of anticoagulation. In total, 110 PaC patients, 93% with advanced or metastatic disease, treated with N–G and tinzaparin (10,291 ± 1176 Anti-Xa IU, OD, median duration 8.7, IQR: 5.6–11.9 months) were enrolled. Of these, 52% were males and; the median age was 68 (40–86 years). The tumor was located to in the pancreatic head at in 45% of the patients. The median PFS was 7.9 months (IQR: 5.0–11.8 months). Out of 14 similar studies (involving 2994 patients) identified via systematic search, it was determined that the weighted PFS of patients receiving N–G but no anticoagulation was 5.6 months. Therefore, patients receiving tinzaparin had 39.54% higher PFS than patients without thromboprophylaxis (p < 0.05). During the follow-up period of 18.3 ± 11.7 months, three (2.7%) thrombotic events were recorded while two clinically relevant non-major bleeding events occurred (1.9%). In conclusion, PFS in advanced PaC patients undergoing chemotherapy is positively impacted by anticoagulation. Thromboprophylaxis with tinzaparin in treatment dose is efficient and safe.
