Clinical implications of KRAS mutations in advanced non-small cell lung cancer remain unclear. We retrospectively evaluated the prognostic and predictive value of KRAS mutations in patients with advanced NSCLC. Among 484 patients with available results for both KRAS and EGFR mutations, 39 (8%) had KRAS and 182 (38%) EGFR mutations, with two cases having both mutations. The median overall survivals for patients with KRAS mutations, EGFR mutations, or both wild types were 7.7, 38.0, and 15.0 month

BACKGROUND: The current standard treatment for patients with inoperable, locally advanced esophageal squamous cell carcinoma (ESCC) is definitive concurrent chemoradiotherapy (CCRT). METHODS: Patients with locally advanced ESCC received 2 cycles of 5-fluorouracil, cisplatin, durvalumab, and tremelimumab every 3 weeks with concurrent radiation therapy (60.2 or 64.5 grays). After completing CCRT plus immunotherapy, patients received 2 cycles of consolidative durvalumab and tremelimumab followed by

PURPOSE: We investigated whether thymidylate synthase (TS) expression is a predictive marker for the clinical outcome of pemetrexed/cisplatin in patients with nonsquamous non-small-cell lung cancer. PATIENTS AND METHODS: Eligible patients were tested for TS expression by immunohistochemistry and stratified into either a TS-negative or a TS-positive group. After stratification, patients in each group were randomly assigned (1:1 ratio) to receive either pemetrexed/cisplatin or gemcitabine/cisplati
