集学的治療で長期にコントロールできた前立腺平滑筋肉腫の1例

Abstract

A 67-year-old man presented with macroscopic hematuria. Transrectal prostatic needle biopsy was performed because of elevated prostate specific antigen (PSA) (3.85 ng/ml) and palpation of hard nodules at the prostate. Pathological diagnosis was leiomysarcoma. Computed tomography revealed several pulmonary metastases. Radical cysto-prostatectomy and construction of ileal conduct were performed. Adjuvant radiotherapy (50 Gy) was also performed. During follow-up, the size of the pulmonary metastases increased, and we decided to start systemic chemotherapy 7 months after surgery. The chemotherapy consisted of gemcitabine (900 mg/m2 on day1 and day 8), and docetaxel (100 mg/m2 on day 8). After eight courses, there was 20% reduction in the size of some pulmonary metastases. He remained alive 21 months after diagnosis.
