We aimed to compare FOLFIRI and bevacizumab with FOLFIRI and aflibercept in terms of overall survival (OS), progression-free survival (PFS) and safety in patients with RAS-mutant metastatic colon cancer who progressed after first-line FOLFOX or XELOX and bevacizumab treatment. This retrospective study included 243 patients from 15 different centres in Turkey. The endpoints of the study were OS, PFS and safety and side effect outcomes.

: In this study, we evaluated the impact of seven immune indexes on treatment response and survival outcomes in advanced non-small-cell lung cancer (NSCLC) patients receiving second-line and subsequent nivolumab treatment under real-life conditions. : The pan-immune inflammation value (PIV), systemic immune inflammation value (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), derived neutrophil-to-lymphocyte ratio (d-NLR), and prognostic nutritional index (PNI) were calculated. All immune indexes were classified as low and high based on cut-off values.

Background: Biliary tract cancers are serious diseases and new biomarkers may be useful for the optimal management and prediction of these cases. This study aimed to evaluate the prognostic significance of the hemoglobin, albumin, lymphocyte, and platelet (HALP) score, a novel composite marker, in patients with metastatic biliary tract cancer.

Methods: Patients with biliary tract cancers were analyzed retrospectively.
