title: [A case report of S-1 single effective use as third-line chemotherapy and re-challenge in a recurrent squamous cell lung cancer patient].
abstract: A 72-year-old male had suffered from a recurrent pulmonary squamous cell carcinoma. He had a history of systemic chemotherapy including carboplatin+paclitaxel(CBDCA+PTX)and docetaxel(DOC). As third-line chemotherapy, this patient was treated with 100 mg of S-1 daily for 4 weeks followed by 2 weeks of rest. Maximal effect was acquired 3.5 months after start of S-1 and resulted in partial response. Since tumors re-grew, S-1 was stopped and other chemotherapies including gemcitabine+vinorelbine(GEM+VNR)and gefitinib were tried but proved ineffective. The tumors gradually grew and, subsequently, right total atelectasis occurred. Re-administration of S-1 showed tumor regression and atelectasis improved. Now this patient is continuing treatment with S-1 monotherapy.
