Osimertinib, a third-generation EGFR tyrosine kinase inhibitor: A retrospective multicenter study of its real-world efficacy and safety in advanced/recurrent non-small cell lung carcinoma.
Abstract
Osimertinib is recommended for T790M mutation-positive advanced non-small cell lung cancer (NSCLC) resistant to first- and second-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs). Recently, some reports exist on the real-world use of osimertinib; however, reports involving third/later-line use are few. Hence, this study was conducted to evaluate the efficacy and safety of osimertinib used in various treatment lines for T790M-positive NSCLC patients. This retrospective, observational, multicenter study included T790M-positive advanced/recurrent NSCLC patients treated with osimertinib from May 2016 to March 2018. The clinical characteristics, efficacy, and adverse events were retrospectively investigated. The Kaplan-Meier method was used to analyze progression-free survival (PFS) and overall survival (OS). PFS-associated clinical characteristics were evaluated using the Cox proportional hazards model. The objective response rate (ORR) and disease control rate (DCR) were 60.7% and 91.1%, respectively; the median PFS was 11.0 months. There were no significant differences in the median PFS for patients treated with osimertinib as second-line and third-/later-line (14.5 vs. 11.0 months respectively...Continue Reading

Anemia
Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
