A 77-year-old man had undergone gastrectomy on June 30, 1992, because of gastric cancer (type II, t1n1, stage IB). When transurethral resection of the prostate was performed because of prostatic cancer in January 1998, a chest X-ray film showed abnormal shadow in the left middle lung field. Chest CT demonstrated a 4 cm-sized tumor in left S6 with slight pleural effusion, and a needle biopsy specimen revealed large cell carcinoma (cT4N0M0, stage IIIB). On March 11, 1998, effusion was sampled thoracoscopically and was negative for malignancy. There was no pleural dissemination. Left lower lobectomy with mediastinal node dissection was performed by open thoracotomy. Histological examination demonstrated large cell carcinoma with poorly differentiated adenocarcinoma (tub, pap) accompanied subcarinal lymph node metastasis. Immunohistologically the lymph node was positive for prostate specific antigen (PSA). The pathological stage was IB (T2N0M0) for lung cancer, and stage D2 for prostatic cancer. The patient has been receiving hormonal therapy for advanced prostatic cancer after these treatments.
