Abstract

Aim

FOLFIRINOX represents an active regimen in first-line treatment of advanced pancreatic adenocarcinoma (PDAC) patients (pts) with good performance status (PS). Aim of this study was to evaluate the presence of existing prognostic criteria in this population.

Methods

We retrospectively investigated clinical and laboratory characteristics of pts treated with first-line FOLFIRINOX regimen for locally advanced or metastatic PDAC between June 2011 and April 2014 in four Italian institutions. Survival estimates were quantified using Kaplan Meier curves. Age, tumor stage, presence of biliary stents, ECOG-Performance Status (PS) and pre-treatment CEA, CA 19-9, LDH, hemoglobin, neutrophil, lymphocyte and platelet counts as well as body mass index (BMI) were included in the Cox analysis to investigate their prognostic relevance.

Results

96 pts treated with FOLFIRINOX as first-line chemotherapy were analyzed. Median age was 61 years (range 36-76); 63 pts were males (66%). PDAC was locally advanced in 46 (48%) and metastatic in 50 pts (52%). Median progression-free survival (PFS) was 4.9 months and median overall survival (OS) was 10.6 months. At multivariate analysis, only ECOG-PS ≥ 2 (p = 0.02) was significantly associated with poor OS. Furthermore, ECOG-PS ≥ 2 (p = 0.040), neutrophilia (p = 0.007) and the presence of biliary stent (p = 0.017) were independent prognostic factor for worst PFS.

Conclusions

Pre-treatment neutrophilia, ECOG-PS ≥ 2 and the presence of biliary stent were independent prognostic factor for patients treated with first-line FOLFIRINOX, suggesting that the use of this regimen in patients with these features should be carefully considered.
