[A case of endobronchial squamous cell lung cancer successfully treated with weekly chemotherapy of carboplatin and paclitaxel].
A 69-year-old man had undergone low anterior resection and a right lobe resection of the liver for rectum cancer and metastatic liver tumor at the age of 66 years. He presented at our hospital because of an abnormal shadow on a CT chest scan, which indicated a tumor shadow 2.5 cm in size in the lingular lobe and enlarged hilar and mediastinal lymph nodes. A bronchoscopic tumor biopsy revealed pulmonary metastasis from the rectum cancer. Bronchoscopic examination also identified an endobronchial squamous cell lung cancer, which almost completely obstructed the orifice of B1 and B2. We concluded that the patient had squamous cell lung cancer with metastases in the mediastinal lymph nodes. He was initially treated with weekly chemotherapy with carboplatin (AUC 1.25) and paclitaxel (70 mg/m2). The endobronchial tumor was markedly reduced in size after 2 weeks of the chemotherapy. Furthermore, after 6 weeks of the chemotherapy, the tumor had disappeared completely, and 11 days later, lower division segmentectomy and hilar and mediastinal lymph node dissection were performed. Pathological examination revealed no metastases in the lymph nodes. The patient has continued to receive chemotherapy as an outpatient and has been well without recurrence of any metastases for over 16 months.
