Clinical analysis of patients treated with afatinib for advanced non-small cell lung cancer: A Nagano Lung Cancer Research Group observational study

Although the survival benefit with afatinib remains unclear, our observational analysis demonstrated the feasibility of using afatinib for EGFR-mutated NSCLC in clinical practice. In particular, a relatively high level of drug delivery is possible. In addition, a lower BSA may be a predictor of diarrhea in patients treated with afatinib.
