Objective: To retrospectively analyze the efficacy and safety of osimertinib combined with anlotinib in the treatment of advanced non-small-cell lung cancer (NSCLC) after drug resistance, and to explore the related factors affecting the efficacy.
Methods: The clinical data of 34 patients with advanced NSCLC who received osimertinib combined with anlotinib as three or more lines of treatment in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from June 2019 to March 2022 were collected, and the therapeutic efficacy and safety were analyzed.
Results: A total of 34 advanced NSCLC patients met the inclusion criteria. The objective response rate was 20.6%, the disease response rate was 88.2%, the median overall survival was 19.0 months, and the median progression-free survival was 6.0 months. The common adverse events were mainly grade 1-2, and only three cases (11.1%) of adverse events were grade 3, including hypertension, proteinuria, and vomiting. No grade 4 or above adverse events were observed. Multivariate Cox regression analysis showed that the Eastern Cooperative Oncology Group Performance Status score and bone metastasis were independent prognostic factors for osimertinib combined with anlotinib as three or more lines of treatment in advanced NSCLC.
Conclusions: Osimertinib combined with anlotinib as three or more lines of treatment in advanced NSCLC was effective and adverse events were tolerable.
