4113 Background: F-NOX is increasingly utilized in BRPC as neoadjuvant therapy. However, prospective data remains limited; the largest series is a 22 patient (pt) cooperative group trial (Alliance A021101), in which 14 pts had R0 resection. In this study, we evaluate neoadjuvant F-NOX followed by individualized chemoradiation (CRT) for BRPC. Methods: Pts ECOG PS 0-1 with biopsy-proven BRPC defined by NCCN criteria were enrolled in a single institution, NCI-sponsored phase II study (NCT01591733). Pts received F-NOX for 8 cycles. If after chemotherapy the tumor was radiographically resectable, pts received short course CRT in 5 (protons 25 GyE) or 10 fractions (photons 30 Gy) with capecitabine 825 mg/m2 bid. If the tumor was still abutting vasculature, pts received CRT to 50.4 Gy with a vascular boost to 58.8 Gy. Primary endpoint was R0 resection rate. Results: 50 pts were enrolled from 8/2012 to 8/2016. Two pts were ineligible (lung metastasis, negative biopsy); 48 pts were evaluable. Median age was 62y (46-74). Median tumor size was 37 mm (21-56). Thirty-six pts (75%) had pancreatic head tumors. Median follow up was 18.2 months among 31 patients still alive. Of the evaluable pts, 40 (83%) completed therapy. Reasons for not completing therapy include pt withdrawal (3), physician decision (3), unacceptable toxicity (1) and progression (1). Grade 3 or greater toxicity occurred in 48% of pts, but no individual grade 3 toxicity exceeded 15%. Twenty-seven pts (56%) had short course CRT, while 13 pts (27%) had long course CRT. Twenty-nine pts were resected; R0 resection was achieved in 28/29 (96.5%). R0 resection rate among all evaluable pts was 58.3%. Median PFS among all evaluable pts was was 14.7 months; mOS was 37.7 months, with 1y OS 79.5% and 2y OS 59.3%. Among resected patients, mOS has not been reached. 1y PFS was 78.1% and 2y PFS 55.4%; 1y OS was 92.6% and 2y OS was 80.6%. Conclusions: Preoperative F-NOX followed by individualized chemoradiation in BRPC results in high R0 resection rates as well as prolonged mPFS and mOS in this large prospective cohort. Clinical trial information: NCT01591733.

368 Background: F-NOX has been increasingly utilized in borderline resectable pancreatic cancer (BRPC) due to the improved response rate compared to gemcitabine. However, prospective data remains limited, with the largest series being a 22 patient (pt) cooperative group trial (Alliance A021101), in which 14 pts had R0 resection. In this study, we evaluate neoadjuvant F-NOX followed by individualized chemoradiation (CRT) for BRPC. Methods: Pts ECOG PS 0-1 with biopsy-proven BRPC as defined by NCCN criteria (SMV/PV involvement with suitable flow, abutment of SMA < 180 degrees or of hepatic artery) were enrolled in a single institution, NCI-sponsored phase II study (NCT01591733). Pts received F-NOX for 8 cycles. If after chemotherapy, the tumor was radiographically resectable, pts received short course CRT in 5 (protons 25 GyE) or 10 fractions (photons 30 Gy) with capecitabine 825 mg/m2 bid. If the tumor was still abutting vasculature, pts received CRT to 50.4 Gy with a vascular boost to 58.8 Gy. The primary endpoint of the study was R0 resection rate. Results: 50 pts were enrolled from 8/2012 to 8/2016. One pt was ineligible (lung metastases) and 1 pt is still on treatment, thus 48 patients were evaluable for this analysis. Median age was 62y (46-74). Median tumor size was 37 mm (21-56). Tumor location was in the head of pancreas for 36 (75%) pts. Of the evaluable pts, 40 (83%) completed therapy. Reasons for not completing therapy included pt withdrawal (3), physician decision (3), unacceptable toxicity (1) and progression (1). Grade 3 or greater toxicity occurred in 21 (44%) pts, including diarrhea (6, 12%), febrile neutropenia (4, 8.5%), neutropenia (4, 8.5%), elevated AST/ALT (3, 6.2%), thrombocytopenia (2, 4.2%), anemia (2, 4.2%), elevated alkaline phosphatase (2, 4.2%). 27 (56%) had short course CRT, while 13 (27%) had long course CRT. In evaluable pts, R0 resection rate was 28/40 (58%). Conclusions: Preoperative F-NOX followed by individualized chemoradiation results in a high R0 resection rate. Final results including PFS outcomes on the entire cohort will be presented at the meeting. Clinical trial information: NCT01591733.

4107 Background: Borderline resectable pancreatic cancer (BRPC) has a high probability of a positive surgical margin and poor prognosis because the tumor interacts with surrounding arteries or veins. Chemoradiotherapy (CRT) with S-1 has shown favorable activity in locally advanced pancreatic cancer. This study was designed to assess S-1 and concurrent radiotherapy in a neoadjuvant setting to determine whether it increases R0 resection rate for BRPC. Methods: This was a multicenter, single-arm phase II study. Patients with BRPC received S-1 (40 mg/m2 BID) and concurrent radiotherapy (50.4 Gy in 28 fractions) before surgery if they fulfilled any of the following: (1) bilateral impingement of superior mesenteric vein or portal vein; (2) tumor contact with superior mesenteric artery ≤180°; or (3) tumor contact with common hepatic artery or celiac axis ≤180°. Primary endpoint was R0 resection rate in BRPC confirmed by central review. At least 40 patients were required, with one-sided α = 0.05 and β = 0.05, with an expected and a threshold values for primary endpoint of 30% and 10%. Results: Fifty-two patients were eligible between December 2012 and May 2016. CRT was completed in 50 patients (96%) and was safe, with mostly grade 1 or 2 adverse events. Protocol treatment was withdrawn before surgery in 12 patients because of progressive disease diagnosed by computed tomography, and in one because of treatment refusal. Ten patients received exploratory laparotomy, or palliative/noncurative resection. In the rest of 29, R0 resection was conducted in 27, and R1 and RX in 1 patient each. This gave an R0 resection rate of 52% in all 52 eligible patients. In the 41 cases of BRPC confirmed by central review, R0 was confirmed in 26 (63%). Destruction of > 50% of tumor cells was confirmed pathologically in 10 (32%). Postoperative grade III/IV adverse events according to Clavien–Dindo classification were observed in 6 (15%). Conclusions: S-1 and concurrent radiotherapy were well tolerated and found to be effective in BRPC. A randomized controlled trial comparing neoadjuvant CRT and chemotherapy, including gemcitabine+nab-paclitaxel, for BRPC is under planning. Clinical trial information: NCT02459652.

4127 Background: Borderline resectable pancreatic cancer (BRPC) is frequently associated with positive surgical margins and a poor prognosis when treated with upfront surgery. This study was designed to assess whether neoadjuvant chemoradiotherapy (CRT) with S-1 increases the R0 resection rate. Methods: This was a multicenter, single-arm, phase II study. Patients with BRPC received S-1 (40 mg/m2 bid) and concurrent radiotherapy (50.4 Gy in 28 fractions) before surgery if they fulfilled any of the following: (1) bilateral impingement of the superior mesenteric vein or portal vein; and (2) tumor contact ≤180° with the superior mesenteric artery, common hepatic artery, or celiac axis. The primary endpoint was the R0 resection rate in BRPC confirmed by central review. Secondary endpoints were overall survival (OS), progression-free survival (PFS), response rate (RECISTv1.1), pathological response rate, surgical morbidity (Clavien–Dindo classification), and toxicity (CTCAEv4.0). At least 40 patients were required, with one-sided α = 0.05 and β = 0.05, with an expected and threshold value for the primary endpoint of 30% and 10%. Results: Fifty-two patients were eligible, of whom 41 had BRPC by central review. CRT was completed in 50 (96%) patients and was well tolerated. The rate of grade 3/4 toxicity with CRT was 43%. The R0 resection rate was 52% (95% CI, 37.6%–66.0%) in 52 eligible patients and 63% (95% CI, 46.9%–77.9%) in 41 patients with BRPC. The radiological response rate was 5.8%, while destruction of > 50% of tumor cells was shown microscopically in 32% of patients. Postoperative grade III/IV adverse events were observed in 7.5% of operated patients. Among the 52 eligible patients, the 2-year OS rate, median OS, and median PFS were 51%, 25.8 mo, and 6.7 mo. Of the 41 patients with BRPC, the 2-year OS rate, median OS, and median PFS were 58%, 30.8 mo, and 10.4 mo. Conclusions: S-1 and concurrent radiotherapy appear to be feasible and effective at increasing the R0 resection rate with encouraging survival rates in BRPC. A phase II/III trial evaluating this treatment is ongoing. Clinical trial information: NCT02459652.

381 Background: Preoperative therapy in BRPC is intended to increase the likelihood of R0 resection although an optimal regimen is yet to be defined. Methods: Patients (pts) with BRPC (NCCNv.2.2010 guidelines) and ECOG PS 0-1 were enrolled in a single-institution, phase II trial (NCT01661088). Pts received FOLFIRINOX x 6, followed by IMRT (50 Gy in 25 fractions) concurrent with FDR-gemcitabine 1 g/m2 on days 1, 8, 22, 29. Two additional FDR-gemcitabine infusions completed pre-operative treatment. Pancreatic protocol CT scans (dual phase, 0.65 mm slices) were performed after 4 infusions of FOLFIRINOX, 3 weeks after IMRT, and at treatment completion. Pts without distant disease were offered surgical exploration. The primary objective was to determine R0 resection rate. Secondary objectives included progression free survival (PFS), overall survival (OS), response rate and safety. Results: A total of 25 pts (64% men) median age 60 years (range 47-77) were enrolled from 11/2011 through 01/2017. Twenty-one (84%) pts completed FOLFIRINOX and 19 (76%) all protocol therapy. Treatment-related grade 3-4 adverse events ( > 10%) included neutropenia (40%), nausea/vomiting (28%), diarrhea (16%) and fatigue (12%). One early death and 1 discontinuation due to toxicity occurred during FOLFIRINOX. Response to pre-op therapy included 11 PR, 9 SD, 3 PD and 2 NE. Of 25 treated pts, 18 (72%) had laparotomy and 13 (52%) underwent resection (all R0). The median PFS and OS were 18.1 (95% CI, 10.6 to 25.1) and 24.2 (95% CI, 12.6 to 40.0) months, respectively. The median OS for R0 resected pts was 37.1 (95% CI, 15.4 – not reached) months. Conclusions: Neoadjuvant therapy with FOLFIRINOX, followed by IMRT with concurrent FDR-gemcitabine in BRPC is feasible and tolerated. While R0 resection rate was not obviously improved, OS of the entire cohort and especially in R0 resected pts was favorable. Clinical trial information: NCT01661088.

275 Background: FOLFIRINOX exhibits a meaningful improvement in outcome measures in metastatic pancreatic cancer, making it an interesting regimen for BRPC and LAURPC. However, its use remains prohibitive due to toxicity. In this study, we examine the outcomes of mFOLFIRINOX as a neoadjuvant strategy for patients with BRPC and LAURPC. Methods: This is a retrospective analysis of a prospectively maintained database of patients who received mFOLFIRINOX for BRPC or LAURPC at Ohio State University. mFOLFIRINOX is as follows: irinotecan at 165 mg/m2; oxaliplatin at 85 mg/m2; 5-fluorouracil (5FU) at 2,400 mg/m2 over 46 hours and pegfilgrastim on day 4 of each 2-week cycle. Cases were thoroughly reviewed by a multidisciplinary team prior to initiation of therapy and at each restaging scan. The primary outcomes of this analysis were resection rate and grade 3/4 (G3/4) toxicities. Results: Since 1/1/2011, 43 patients (20 BRPC; 23 LAURPC) have received mFOLFIRINOX. Patients received gemcitabine-based chemoradiation (36 Gy in 15 fractions) only if their best response was stable disease after 4 months of mFOLFIRINOX. At the time of this abstract, 39 patients are evaluable for primary outcome. Overall resection rate was 53.8% including 45% of patients with initially unresectable disease. R0 resection was achieved in 85.7% of the surgeries. See table for more results. The rate of G3/4 toxicity was remarkably low with no episodes of febrile neutropenia, G3/4 neutropenia or thrombocytopenia. Toxicities lead to dose reductions in 46% of patients. Conclusions: Neoadjuvant mFOLFIRINOX is an effective, well-tolerated regimen as part of an integrated, multimodality strategy in BRPC and LAURPC leading to high resection rates and high R0 resection frequency.

4051 Background: Preop therapy for resectable pancreatic cancer (PC) maximizes access to multimodality therapy and increases the R0 resection rate. Based on our phase I chemoradiation (chemoRT) trial in PC patients, we hypothesized that the addition of bev to gem-based chemoRT in pts with resectable PC may allow more pts to undergo pancreaticoduodenectomy (PD), improve the rate of R0 resections, and prolong overall survival. Methods: Pts with biopsy proven, stage I/II adenocarcinoma of the pancreatic head or uncinate process received 6 weekly infusions of gem (400 mg/m2) and 3 infusions of bev (10 mg/kg, every 2 wks) with concomitant RT, 50.4 Gy at 1.8 Gy/fr. Pts were restaged 4-6 wks after the last dose of radiation. Those without disease progression and with good PS underwent surgery. Pts with adequate recovery received bev (10 mg/kg) every 2 weeks for 3 mo starting ~ 6 wks after surgery. Results: This study enrolled 11 of a planned 31 pts but was terminated early due to unforeseen postop complications. Median age is 64 yrs; all pts had ECOG-PS 0-1. Median CA19-9 was 52. Median follow-up from surgery was 41 mths. All completed chemoRT; 10 underwent restaging and 1 pt died from cardiac arrest before restaging. 9 pts (90 %) went to surgery and underwent a successful R0 PD. Pathologic PR rate (>50 % tumor kill) was 56 %. As we have previously reported, preop grade 3-4 toxicities were infrequent and major postop complications occurred in 5 of the 9 pts (56%) who underwent PD. Median overall survival (OS) was 30.1 mths (range: 2.6 - 63.9) for the entire cohort. Of the 9 resected pts, median OS was 45.5 mths with 5 of 11 pts (45%) achieving survival longer than best historical control (median 58.2 mths). Conclusions: The addition of bev to our prior backbone of gem-based preoperative chemoRT led to a higher resection rate (90%) than our previous protocols. Updated survival results of this study are promising. Taken together, these results may prompt further investigation of this regimen with modifications in the timing of bev delivery.

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.

216 Background: Perioperative treatments have significantly improved survival in patients with resectable gastric cancer, increasing 5-year overall survival from 23% with surgery alone to 45% with FLOT, Although FLOT has been recognized as the first choice for neoadjuvant chemotherapy in gastric or GEJ adenocarcinoma, its efficacy needs to be improved. Sintilimab, a fully human IgG4 monoclonal antibody that binds to programmed cell death receptor-1 (PD-1), has shown remarkable clinical efficacy in various cancers. We aimed to assess the activity and safety profile of the combination of FLOT and sintilimab for neoadjuvant treatment of gastric or GEJ adenocarcinoma. Methods: In this ongoing, single-arm, phase II study, we recruited patients from Henan Cancer Hospital in China with histopathologically diagnosed resectable gastric or GEJ adenocarcinoma who had clinical T3/N+ or higher stage. Patients were given 4 cycles of FLOT (docetaxel 50 mg/m2, oxaliplatin 80 mg/m2, leucovorin 200 mg/m2, fluorouracil 2600 mg/m2, 24-h infusion on day 1, q2w) in combination with 3 cycles of sintilimab (200mg, iv, d1, q3w), followed by D2 surgery and 4 postoperative cycles of FLOT. The primary endpoint was pathological complete response (pCR). The secondary endpoints included major pathological remission (MPR) and R0 resection rate and adverse events . Results: A total of 20 patients were enrolled in the study between Aug 10 2019 and Sep 15 2020. One patient refused surgery, one person's disease progressed. Two patients have not yet completed neoadjuvant treatment . 16 pts who experienced D2 resection, 10 (62.5%) achieved major pathologic response (MPR), including 3 (18.8%) with a pathologic complete response (pCR) in primary tumor. The R0 resection rate was up to 93.8%, The grade 3 or 4 treatment-related adverse events (TRAE) included lymphopenia(25%), anaemia (20%),fatigue (20%),leucopenia (15%), neutropenia (5%), diarrhea(5%), Alanine aminotransferase increased(5%),There was no surgical delays or unexpected surgical complications related to drug toxicity. Conclusions: Neoadjuvant combination of sintilimab and FOLT is a safe and efficacious treatment option for patients with gastric or GEJ adenocarcinoma, 18.8% pCR rate and 62.5%MPR rate is encouraging. Our clinical study is still enrolling, and the survival effects are under follow up. Clinical trial information: NCT04341857.

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.
