Abstract Background The added value of radiotherapy following neoadjuvant FOLFIRINOX chemotherapy in patients with resectable or borderline resectable pancreatic cancer ((B)RPC) is unclear. The objective of this meta-analysis was to compare outcomes of patients who received neoadjuvant FOLFIRINOX alone or combined with radiotherapy. Methods A systematic literature search was performed in Embase, Medline (ovidSP), Web of Science, Scopus, Cochrane, and Google Scholar. The primary endpoint was pooled median overall survival (OS). Secondary endpoints included resection rate, R0 resection rate, and other pathologic outcomes. Results We included 512 patients with (B)RPC from 15 studies, of which 7 were prospective nonrandomized studies. In total, 351 patients (68.6%) were treated with FOLFIRINOX alone (8 studies) and 161 patients (31.4%) were treated with FOLFIRINOX and radiotherapy (7 studies). The pooled estimated median OS was 21.6 months (range 18.4–34.0 months) for FOLFIRINOX alone and 22.4 months (range 11.0–37.7 months) for FOLFIRINOX with radiotherapy. The pooled resection rate was similar (71.9% vs. 63.1%, p = 0.43) and the pooled R0 resection rate was higher for FOLFIRINOX with radiotherapy (88.0% vs. 97.6%, p = 0.045). Other pathological outcomes (ypN0, pathologic complete response, perineural invasion) were comparable. Conclusions In this meta-analysis, radiotherapy following neoadjuvant FOLFIRINOX was associated with an improved R0 resection rate as compared with neoadjuvant FOLFIRINOX alone, but a difference in survival could not be demonstrated. Randomized trials are needed to determine the added value of radiotherapy following neoadjuvant FOLFIRINOX in patients with (B)PRC.

Abstract Objective: The study aimed to investigate the effect of body composition changes during chemotherapy on clinical outcomes in patients with pancreatic cancer.Results: In patients with locally advanced pancreatic cancer (LAPC), the cross-sectional area of skeletal muscle (SM) and adipose tissue (AT) at the level of third lumbar vertebra was measured. The SM and AT ratios indicated the changes during chemotherapy. The patients were classified into three groups based on these ratios: group 1, ≥1.00; group 2, 0.85-0.99; group 3, <0.85. The overall survival (OS) and surgical resection rates were estimated. Fifty-eight patients with LAPC who received first-line FOLFIRINOX were analysed. Fifteen (25.9%) patients who underwent resection showed maintained BMI, SM, and AT as compared to the patients who did not undergo resection. As the SM ratio decreased, the risk for death increased significantly. Further, the resection rate was significantly higher in patients with maintained SM compared to those with low SM ratio. On the contrary, the change in AT ratio was not associated with OS and resection rate; however, significant decrease in AT more than 15% showed poor clinical outcomes. Maintenance of SM during chemotherapy is a reliable prognostic factor indicating longer OS and higher resection rate.

e16268 Background: The multi-kinase inhibitor sorafenib (S) and HDAC inhibitor vorinostat (V) demonstrated synergism against preclinincal pancreatic cancer (PaCa) models. The combination of S & V also potently radiosensitized pancreatic cancer cells and enhanced the activity of gemcitabine (G). This led to a phase 1 trial to determine the doses and schedule appropriate for phase 2 study of S & V with weekly G and intensity modulated radiotherapy (IMRT) as neoadjuvant treatment of PaCa following chemotherapy. Methods: Using a 3+3 dose-escalation design, adult patients with resectable, borderline resectable, unresectable, and lymph node positive PaCa were enrolled to 6 dose levels. Enrolled patients had completed at least 8w of neoadjuvant chemotherapy prior to IMRT. The schedule of administration was weekly 200mg/m2 G weekly during IMRT, S & V were dosed either 3x or 5x weekly during IMRT. Primary endpoint was to identify the dose and schedule for S & V with G based chemoradiation. Key secondary endpoints included antitumor activity, R0 resection rate, OS. Correlative studies to evaluate a variety of biomarkers and Nanostring expression analysis on pre- and post-therapy tumor specimens were also performed. Results: 22 patients were enrolled and 21 treated at 6 dose levels. Due to thrombocytopenia limiting drug exposure, the trial was modified to reduce G to 200mg/m2/wk and S & V to 3 d/wk instead of 5 d/wk. 13 patients were eligible for surgery, and 9 had R0 resections. Conclusions: Our findings indicate that the study regimen was well tolerated, typical toxicities of S (hand foot syndrome) were not observed with intermittent dosing. Uncomplicated cytopenias limited drug exposure, which was improved with intermittent S&V dosing. The RP2D of the combination is S (400mg po BID 3d/wk), V (200mg po qd 3d/wk), G 200mg/m2 IV weekly, with IMRT (50.4 Gy over 28 fractions, 5d/wk). Antitumor activity was observed across dose levels, with an encouraging R0 resection rate. These results warrant further investigation of combining S and V with G and IMRT as neoadjuvant treatment of PaCa following chemotherapy. Analyses of correlative studies and OS are underway. Clinical trial information: NCT02349867. [Table: see text]

280 Background: Multimodality therapy has been advocated for borderline resectable pancreatic cancer (BRCP); however, specific regimens vary widely by institution. Outcomes of these interventions need to be examined to inform future investigation of the optimal therapy for these patients. This study represents the experience of multimodality therapy for BRPC at an NCI designated cancer center. Methods: We identified all patients (pts) with operable pancreatic ductal adenocarcinoma (PDA) from 2006 to 2011. Patients were divided into two groups: resectable group and BRPC group as per the NCCN and AHPBA consensus guidelines. Primary outcomes were resection rate, microscopic negative margin (R0) resection rate, overall survival (OS), and disease free survival (DFS). Fisher's exact and chi-square were used for group comparison while Kaplan-Meier estimates was used for survival analysis. Results: 160pts were identified with operable PDA. 100 (63%) pts had resectable tumors, and 60 (37%) pts had borderline resectable tumors. Neoadjuvant therapy (NT) was administered to 0% in the group with resectable tumors, and 100% in the group with borderline resectable tumors. The resection rate was 100% in pts with resectable tumors and 58% in pts with borderline resectable tumors. R0 resection rates were 80% in the resectable tumors and 97% in the borderline resectable tumors following NT. Perioperative mortality was <1% (1/125) for resectable tumors and 0% in borderline resectable tumors. Median OS was 22.6 months (m) for pts that had resectable tumors and 13.9m for all pts with borderline resectable tumors (p=0.017); however, the median OS for resected pts with borderline resectable tumors was 21.5m (p=0.6). Improved DFS was seen in patients with resectable tumors when compared with resected borderline resectable tumors (15 vs. 9.5m; p=0.04). Conclusions: Multimodality therapy leads to high rates of R0 resections in borderline resectable pancreatic cancer; however 42% of patients progressed during NT. The overall survival for patients with resected borderline resectable pancreatic cancer following NT is similar to patients who undergo resection for resectable pancreatic cancer.

The Impact

e15052 Background: Pancreatic resection is the only known curative option for pancreatic adenocarcinoma. Resection has been previously reported to be underutilized in patients with early stage disease. To develop a better understanding of this issue and control for treatment selection factors, we examined the relationship between geographic area resection rates and survival in patients with stage I/II pancreatic cancer. Methods: We queried Surveillance, Epidemiology, and End Results (SEER) data for patients with stage I/II cancer of the pancreatic head diagnosed from 2004-2009. We excluded patients with less than 3mo survival. Resection rates were calculated within Health Service Areas (HSAs) across all 18 SEER regions. Resection rate was defined as the number of patients who had an operation divided by the total number diagnosed with early stage pancreatic cancer. Multivariate Cox regression was used to estimate the overall survival effect of HSA rates while controlling for age, gender, marital status, poverty level, education, and AJCC stage. Results: 8,323 patients with stage I (n=1,454) and stage II (n=6,869) disease were analyzed. Pancreatectomy was performed in 476 patients (32.7%) with stage I disease and 3,846 (56.0%) with stage II disease. HSA resection rates were arranged into five groups (quintiles) which ranged from 42.7 to 65.7% (Table). Across the quintiles, median overall survival increased from 11 to 14 months, suggesting a positive association with resection rate. Multivariate analysis revealed that for every 10.00% increase in resection rate, the risk of overall death decreased by 5.26% (p<0.001). Conclusions: Patients with early stage pancreatic cancer who live in areas with higher resection rates have longer average survival times. Because geography should not influence treatment response, we conclude that efforts to raise resection rates should increase survival times in patients for whom there is uncertainty about the risk/benefits of resection.

387 Background: Pancreatic cancer (PC) outcomes remain poor, recent series show approximately 37% of patients achieve R0 resection (all margins ≥ 1mm) for resectable disease. Recent data in metastatic disease shows that nab-paclitaxel (nab-PC) and gemcitabine (GEM) chemotherapy (CX) is an active regimen. We aimed to determine the feasibility and R0 resection rate with peri-operative nab-PC and GEM for resectable PC. Methods: A multicentre, single arm, phase 2 trial. Patients with operable PC received 2 cycles of neo-adjuvant GEM 1000mg/m2 and nab-PC 125mg/m2CX on days 1, 8 and 15 of a 28 day cycle followed by surgical resection and then 4 cycles of post-operative CX. The primary endpoint was R0 resection with the aim to assess if a rate of 85% could be achieved. Secondary endpoints included feasibility, toxicity, pathological response (College of American Pathologists Cancer Reporting Protocol for Exocrine Pancreatic Cancer, 2009), recurrence and survival. Results: Forty-one patients were enrolled from 2012-14. Median age was 65 (range 43-79), 41% male, 49% stage I and 51% stage II. Twenty nine (71%) patients underwent resection with evaluable cancer: 1 did not have proven cancer on central pathology review; 5 did not go to surgery (2 disease progression, 2 refused surgery, 1 due to cholangitis); and in 6 patients surgery was abandoned (unresectable disease). No deaths were surgery-related. Median tumor size was 27.5mm (IQR = 25-35). Pre-operative GEM and nab-PC produced an R0 rate of 52% (15/29) (95% CI 34-69%). 15/29 (52%) of resected tumors showed grade 0-2 tumor regression grade. Twenty-nine patients (71%) experienced >1 grade 3/4 toxicities (total 52 events) during pre-operative CX, neutropenia (46%) being most frequent with 8% febrile neutropenia. 39/41 (95%) patients received 2 cycles of pre-operative CX. Conclusions: Peri-operative GEM and nab-PC CX is feasible and well tolerated. The pre-operative regimen was associated with an R0 resection rate comparable or higher than surgical series without pre-operative therapy, although the primary endpoint of 85% could not be met. The value of this regimen will also depend on longer term outcomes related to recurrence and survival. Clinical trial information: 12611000848909.
