195PHGCSG1601: A retrospective cohort study of the efficacy and safety of nab-paclitaxel plus gemcitabine (nab-P+GEM) for unresectable locally advanced pancreatic cancer (LAPC)

Abstract Background The regimens of nab-P+GEM have become available for advanced pancreatic cancer, especially metastatic disease. However, there are not enough data of nab-P+GEM for LAPC. Methods This is a retrospective multiple institutes cohort study using medical records of LAPC patients who received nab-P+GEM between January 2015 and September 2017. We have surveyed their characteristics and treatment outcomes. Results The number of relevant patients was 48 at 11 institutes. Median age was 68 years old, male/female : 22/26, ECOG PS 0/1/2 : 33/13/2, primary site; head/body/tail : 28/18/2. Relative dose intensity was nab-P; 0.588 (0.065-1.012) and GEM; 0.656 (0.368-1.012). Response rate was 27.0% and Disease control rate was 94.6% among patients who had target lesion. Median progression-free survival was 9.4 months (95% CI, 5.4 – 13.4) and median overall survival was 19.6 months (95% CI, 13.9 – 24.3). The most common adverse event of grade 3 or higher was neutropenia (61.7%). Febrile neutropenia was 8.3%. Conclusions It seemed that nab-P+GEM was effective for patients with LAPC. Prospective and further investigation in more cases is expected. Legal entity responsible for the study Hokkaido Gastrointestinal Cancer Study Group. Funding Has not received any funding.
