Abstract 2438

Background

Presence/absence of family/personal history of breast/ovarian/pancreatic cancer has been reported to be a useful predictive marker in patients with pancreatic adenocarcinoma (PA) receiving platinum-based chemotherapy (Fogelman D, 2015). We planned a prospective phase II study to evaluate the efficacy and safety of platinum-based chemotherapy in this population.

Methods

Eligible patients were those with chemotherapy-naïve metastatic PA with one or more of the following: 1) family history of pancreatic (P)/breast (B)/ovarian (O)/prostate (PR) cancer in a first-degree relative, 2) at least two family members with P/B/O/PR cancer within third-degree relatives, and 3) personal history of B/O/PR cancer. Patients received gemcitabine 1,000 mg/m2 and oxaliplatin 100 mg/m2 every two weeks (GEMOX). The primary endpoint was the one-year survival rate, and the outcome in 19 of 43 patients (pts) (44%) were desired. The target sample size was determined as 43, with a one-sided alpha of 5% and a power of 80%.

Results

A total of 45 pts were enrolled. The first consecutive 43 pts were included in the efficacy analysis. The one-year survival rate (90% confidence interval) was 27.9% (17.0-41.3) and did not meet the expected threshold. The response rate was 27.9%. A tendency towards prolonged survival was observed in patients with two or more family histories of P/B/O/PR cancer (HR 0.65, 95% CI [0.34-1.23]). Presence of a family/personal history of B/O/PR cancer tended to be associated with a better response and longer survival. In this study population, patients with a family history of pancreatic cancer seemed to show a poorer response. The most common adverse events of grade 3 or higher severity were neutropenia (36%), leukopenia (27%) and thrombocytopenia (23%).

Conclusions

GEMOX did not show expected efficacy in patients with metastatic PA with a family/personal history of P/B/O/PR cancer. Selection of GEMOX based on family/personal history alone is not recommended, especially in patients with a family history of P cancer.
