e15193 Background: Nab-Paclitaxel (nab-P) + Gemcitabin (G) and FOLFIRINOX have both shown promising activity in metastatic pancreatic cancer (mPC). Our group has developed sequential usage of both regimens in order to exploit the stromal depletion effects of nab-P and increase global efficacy of chemotherapy in the neoadjuvant setting of LAPC. Methods: This pilot study evaluated patients with cytological/histological confirmed diagnosis of locally advanced pancreatic ductal adenocarcinoma without evidence of metastatic disease (stage III). nab-P+G was administered for 2 cycles (nab-P 125 mg/m2, G 1000 mg/ 2; on days 1, 8, 15; every 28 days) followed by 2 cycles of FOLFIRINOX (as reported by Conroy et al., NEJM 2011). Results: We report the preliminary analysis of 8 pts treated in our institution. Patients characteristics were M/F: 5/3; median age 63 (46-79); PS 0/1: 6/2. 3 pts (37%) had a biliary stent before starting treatment. All pts received the planned 4 cycles of neoadjuvant chemotherapy without dose reductions. There were no treatment-related deaths and none of pts stopped treatment due to toxicity. Grade 3-4 toxicities were neutropenia (50 %), nausea (12%), diarrhea (12%) and thrombopenia (25%). Grade 2-3 sensory neuropathy occured in 25% of pts. Prior nab-P+G did not result in increased hematological or non-hematological toxicity of FOLFIRINOX. Among the 8 patients evaluable so far, 5 partial responses (63%) and 3 stable disease (37%) have been observed, resulting in a disease control rate of 100%. After sequential chemotherapy 3 pts (37%) underwent radical surgical resection. Of note, all resected patients pts showed regression of the tumor (Evans Regression Score 2-4) with 1 patient fullfilling the criteria of a complete pathological remission (pCR). 4 pts received concomitant chemo-radiotherapy and 1 pt underwent an explorative laparotomy with evidence of occult (micronodular) peritoneal metastasis. Conclusions: Sequential neoadjuvant chemotherapy with nab-P+G and FOLFIRINOX seems to be highly active with manageable toxicity profile and may allow to achieve pCR in LAPC. These results are encouraging to test this approach in a prospective phase II trial.

439 Background: Chemoradiation (CRT) induced lymphopenia is common and associated with poorer survival in multiple solid malignancies. The objective of this study was to evaluate the prognostic impact of lymphopenia in patients with nonmetastatic, unresectable pancreatic ductal adenocarcinoma (PDAC) treated by neoadjuvant FOLFIRINOX (5-fluorouracil [5FU]/leucovorin/irinotecan/oxaliplatin) followed by CRT. We hypothesized that severe lymphopenia would correlate with worse survival. Methods: The inclusion criteria for this single-institution retrospective study were: 1) biopsy-proven diagnosis of unresectable PDAC, 2) absence of distant metastasis, 3) receipt of neoadjuvant FOLFIRINOX followed by CRT, and 4) absolute lymphocyte count (ALC) available prior to and two months after initiating CRT. In general, CRT consisted of 5FU or capecitabine and RT with 58.8 Gy over 28 fractions. Lymphopenia was graded according to CTCAE v5.0. The primary variable of interest was lymphopenia at two months, dichotomized by ALC of < 0.5/μl (Grade 3 lymphopenia). The primary endpoint was overall survival (OS). Cox modeling and Kaplan-Meier methods were used to perform survival analyses. Results: A total of 138 patients were identified. Median follow-up for the entire cohort was 16 months. Median age was 65. Fifty-six percent were female, 86% were Caucasian, and 97% had ECOG ≤1. Median tumor size was 3.8 cm. Tumor location was pancreatic head in 63%, body in 22%, tail in 8%, and neck in 7%. Median baseline ALC for the entire cohort was 1.5 k/ul. Two months after initiating CRT, 106 (77%) had severe (Grade 3 or worse) lymphopenia. While there were no significant differences in baseline patient or disease characteristics, patients with severe lymphopenia received higher doses of RT with longer duration of treatment compared to those without severe lymphopenia. On multivariable Cox model, severe lymphopenia at two months was significantly associated with increased hazards of death (HR = 4.00 [95% CI 2.03-7.89], p < 0.001). Greater number of neoadjuvant FOLFIRINOX cycles received prior to CRT was associated with lower hazards of death (HR = 0.84 [95% CI 0.77-0.92], p < 0.001). The 12-month OS was 73% vs. 90% in the cohort with vs. without severe lymphopenia, respectively (log-rank p < 0.001). Conclusions: Treatment-related lymphopenia is common and severe lymphopenia may be a prognostic marker of poorer survival in locally advanced pancreatic cancer. Closer observation in high-risk patients and minimization of RT dose and duration are potential approaches to mitigating CRT-related lymphopenia. Our findings also suggest an important role of the host immunity in pancreatic cancer outcomes, supporting the ongoing efforts of immunotherapy trials in pancreatic cancer.

Borderline Resectable

Despite decades of advancement and research into the multimodal care of pancreatic cancer, mortality after the diagnosis of pancreatic ductal adenocarcinoma remains grim. The role of adjuvant therapy following surgical resection has been well established in the literature. However, adjuvant therapy is imperfect, and outside of a clinical trial, there are high rates of omission or delayed initiation of therapy. Neoadjuvant treatment strategies continue to be explored in the management of resectable, borderline-resectable, and locally advanced unresectable pancreatic adenocarcinoma. With improved resection rates and the possibility for tumor downstaging, neoadjuvant therapy has become standard for patients with borderline-resectable and locally advanced unresectable tumors. Additional benefits of neoadjuvant therapy in the treatment of resectable tumors include improved completion rates of systemic therapy and R0 resection rates. Future clinical trials, including the use of novel treatment agents and combination treatment strategies in both neoadjuvant and adjuvant regimens, will add value to the treatment of pancreatic adenocarcinoma. Key words: adjuvant therapy, borderline-resectable pancreatic cancer, locally advanced pancreatic cancer, neoadjuvant therapy, pancreatic adenocarcinoma, resectable disease

Conversion Rates

While primarily unresectable locally advanced pancreatic cancer (LAPC) used to be an indication for palliative therapy, a strategy of neoadjuvant therapy (NAT) and conversion surgery is being increasingly used after more effective chemotherapy regimens have become available for pancreatic ductal adenocarcinoma. While high-level evidence from prospective studies is still sparse, several large retrospective studies have recently reported their experience with NAT and conversion surgery for LAPC. This review aims to provide a current overview about different NAT regimens, conversion rates, survival outcomes and determinants of post-resection outcomes, as well as surgical strategies in the context of conversion surgery after NAT. FOLFIRINOX is the predominant regimen used and associated with the highest reported conversion rates. Conversion rates considerably vary between less than 5% and more than half of the study population with heterogeneous long-term outcomes, owing to a lack of intention-to-treat analyses in most studies and a high heterogeneity in resectability criteria, treatment strategies, and reporting among studies. Since radiological criteria of local resectability are no longer applicable after NAT, patients without progressive disease should undergo surgical exploration. Surgery after NAT has to be aimed at local radicality around the peripancreatic vessels and should be performed in expert centers. Future studies in this rapidly evolving field need to be prospective, analyze intention-to-treat populations, report stringent and objective inclusion criteria and criteria for resection. Innovative regimens for NAT in combination with a radical surgical approach hold high promise for patients with LAPC in the future.
