381 Background: No established second-line treatment (2L) is available for patients (pts) with advanced biliary tract cancer (ABC) failing gemcitabine/platinum first-line chemotherapy (CT). However, 20-40% of pts are offered 2L CT in daily practice. We evaluated the impact of clinical and biochemical parameters on survival of ABC in order to identify factors aiding in 2L treatment selection. Methods: Medical records of consecutive ABC pts treated with 2L CT between 2005 and 2018 at the Modena Cancer Centre were reviewed. Log-rank test and multiple Cox proportional hazard regression were performed to assess the prognostic significance of covariates on OS. A prognostic score was developed from the multivariate model. Results: A total of 98 pts were identified and included in the analysis. Median (m) age was 63 years, 52% of pts were female, 75% had ECOG PS of 1-2. 72% of pts received first-line gemcitabine/platinum combination. In the 2L setting, 70% of pts received a doublet and the most common regimen was FOLFIRI (26%), followed by FOLFOX (20%) and fluoropyrimidine monotherapy (19%). Disease control rate was 39%, with 7% of objective responses. mOS and mPFS were 7.2 months and 3.5 months, respectively. At both univariate and multivariate analysis ECOG PS > 0 ( P= 0.002), peritoneum involvement ( P< 0.001), LDH > 430 UI/L ( P< 0.001), albumin < 3.5 g/dL ( P= 0.001), gamma-GT > 100 UI/L ( P= 0.001), PFS to first-line < 6 months ( P= 0.025), Na+ < 140 mEq/L ( P= 0.010), absolute lymphocyte count < 1000/uL ( P= 0.030) were significantly associated with shorter OS. By assigning to each of the 8 variables weight = 1, three different risk groups were identified: low-risk group (0-2 factors), intermediate-risk group (3-4 factors) and high-risk group (5-8 factors). mOS was 18, 9.4, and 2.9 months in the low-, intermediate-, and high-risk group, respectively ( P< 0.001). Conclusions: Our 2L study confirms the prognostic value of ECOG PS, PFS to first-line and peritoneal carcinomatosis, identifies novel biochemical prognosticators and proposes a readily-available and inexpensive score to risk stratify patients both in daily practice and clinical trials.
