Abstract

Aim

A variety of cytotoxic agents, either alone or in combination, have been evaluated as first-line chemotherapies for patients (pts) with locally advanced or metastatic pancreatic cancer. However, no standard of care exists. Aim of this study was to evaluate the prognostic significance of different first-line chemotherapies in pts with pancreatic ductal adenocarcinoma (PDAC).

Methods

We retrospectively investigated clinical and laboratory data of pts treated with first-line chemotherapy for PDAC between January 2005 and April 2014 in four Italian institutions. Survival estimates were quantified using Kaplan Meier curves. Age, sex, ECOG-Performance Status (PS), tumor stage, pre-treatment CEA and CA 19-9 and first-line chemotherapy were included in the Cox analysis to investigate their prognostic relevance.

Results

479 pts were included in this analysis. Median age was 66 years (range 36-88); 274 pts were males (57%). Median overall survival (OS) was 7.9 months (range 0.3-60.8), while median PFS was 3.4 months (range 0.3-44.2). OS was 4.7, 7.5, 10.7 and 11.7 months in pts treated with gemcitabine (128 pts), gemcitabine and cisplatin/oxaliplatin (216), gemcitabine and capecitabine (39) and Folfirinox (96), respectively (p < 0.001). Similarly, PFS was 2.6, 3.0, 5.8 and 4.9 months (p < 0.001). At multivariate analysis, tumor stage (p < 0.001), ECOG-PS ≥ 2 (p < 0.001) and choice of first-line chemotherapy (p < 0.001) were independent prognostic factors for OS. Furthermore, ECOG-PS ≥ 2 (p = 0.002) and choice of first-line chemotherapy (p < 0.001) were independent predictors of PFS.

Conclusions

Folfirinox regimen showed the highest OS and PFS as compared to gemcitabine alone or in combination with other agents as first-line therapy. The choice of first-line chemotherapy resulted an independent prognostic factor for both OS and PFS of pts with PDAC.
