Introduction: The majority of cases of lung cancer are still diagnosed at a late stage. At this stage, palliative therapeutic options including nonspecific cytotoxic drugs, targeted therapy, or immunotherapy can be utilized. In 2016, immunotherapy was approved in Europe for squamous cell carcinoma and adenocarcinoma. Moreover, afatinib was also approved as second-line therapy for squamous cell carcinoma.
Case report: This article presents a case of a 76-year-old male with squamous cell carcinoma who received nab-paclitaxel as first-line therapy, and his treatment was switched to the tyrosine kinase inhibitor afatinib (40 mg) after disease progression with left lung atelectasis. After receiving afatinib for only 28 days, the atelectasis resolved. No adverse effects were observed from the afatinib therapy.
Discussion: In this case, afatinib 40 mg proved to be an effective alternative treatment for an elderly patient. Treatment choice should be based on the performance status of the patient, cost-effectiveness, and drug treatment guidelines.
