[A case of non-small cell lung carcinoma successfully treated with carboplatin and weekly paclitaxel under renal dysfunction].

A 73-year-old man was admitted to our hospital with productive cough and dyspnea. His chest X-ray and CT scan showed a mass lesion on the lower lung field, pleural effusion on the left side, metastatic lesion in the right lung, and multiple metastases in the liver. The diagnosis was non-small cell carcinoma of the lung. Unfortunately, he had suffered from chronic nephritis; his creatinine level was 2.1, and his creatinine clearance was 29 ml/min. He received 4 courses of combined chemotherapy of carboplatin (AUC 5, day 1) and weekly paclitaxel (60 mg/ m2, day 1, 8, 15) every 4 weeks. His subjective symptoms as side effects were mild except for accidental melena due to colon diverticulum. Almost all lesions identified at admission were regressed by the chemotherapy. Although renal dysfunction often prevents patients with lung cancer from receiving systemic chemotherapies, in this case the combined chemotherapy of carboplatin and weekly paclitaxel proved to be a relatively safe and effective therapy for those patients with renal dysfunction.
