[Molecular pathology of lung adenocarcinomas, EGFR T790M resistance mutation study].

Aim: In our institute, we have been testing EGFR T790M resistance mutations since 2019, which is the most common resistance mutation that develops during first-line, second- line EGFR TKI treatment of EGFR mutant lung adenocarcinomas. The importance of this study is that the identification of this mutation will allow the use of an effective third-generation TKI. In this article, we report on studies from January 2022 to August 2024, compared with our results from the 2019-2021 period.

Sunitinib plus erlotinib versus placebo plus erlotinib in patients with previously treated advanced non-small-cell lung cancer: a phase III trial.

Purpose: Sunitinib plus erlotinib may enhance antitumor activity compared with either agent alone in non-small-cell lung cancer (NSCLC), based on the importance of the signaling pathways involved in tumor growth, angiogenesis, and metastasis. This phase III trial investigated overall survival (OS) for sunitinib plus erlotinib versus placebo plus erlotinib in patients with refractory NSCLC.

Patients And Methods: Patients previously treated with one to two chemotherapy regimens (including one platinum-based regimen) for recurrent NSCLC, and for whom erlotinib was indicated, were randomly assigned (1:1) to sunitinib 37.
