Sumario: | BACKGROUND AND OBJECTIVE: Afatinib is an irreversible ErbB-family blocker with a clinical activity in non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutations. The aim of this study is to assess the safety of afatinib in patients with advanced lung adenocarcinoma. METHODS: Patients with lung adenocarcinoma (stage Ⅲb or Ⅳ) with EGFR mutations were first-line treated with an oral administration of afatinib (40 mg/d) until disease progression. Adverse events, effects, and survival condition were observed. RESULTS: The most common adverse events were diarrhea (n=5, 100%), skin rash (n=4, 80%), and mucositis/stomatitis (n=4, 80%). Moderate toxicities not exceeding grade 3 were observed. Relatively, the most serious adverse reaction was mucositis/stomatitis. Mild diarrhea occurred in all patients. Three patients experienced temporary drug withdrawal and dose reduction because of adverse reaction. Among the four patients who were evaluated, partial response was observed in two patients (50%), one with stable disease (25%) and one with progressive disease (25%). Median progression-free survival was 9.7 months, whereas median overall survival was 18.4 months. CONCLUSION: Afatinib was approved as first-line treatment for patients with advanced lung adenocarcinoma. The most common adverse events were diarrhea and skin rash. However, mucositis/stomatitis related to afatinib should also be considered. Considering the small number of cases, the conclusion requires more trials for confirmation. |
