Phase I Study of Nab-Paclitaxel plus Gemcitabine as Neoadjuvant Therapy for Borderline Resectable Pancreatic Cancer

Abstract

Background/aim: The aim of this study was to investigate the safety and feasibility of neoadjuvant nab-paclitaxel plus gemcitabine therapy for patients with borderline resectable pancreatic carcinoma (BRPC).

Patients and methods: The study was a prospective single-center phase I trial for patients with BRPC. The primary endpoint was the toxicity, and secondary endpoints were the resection rate, the R0 resection rate and quality of life (QOL) regarding the peripheral sensory neuropathy (PSN). This trial was registered on the UMIN Clinical Trials Registry (UMIN000018382) and on ClinicalTrials.gov (NCT02506803).

Results: The overall rate of any grade and grade 3-4 events (CTCAE ver. 4.0 criteria) were 100% and 90%. The majority of these adverse events represented expected neutropenia. The resection and R0 resection rates were 80% and 70%, respectively.

Conclusion: We found that neoadjuvant nab-paclitaxel plus gemcitabine therapy was safe and feasible without stringent selection of patients with BRPC.
