74歳女.初発時,再発時とも術前化学療法と手術療法の組み合わせで治療しえた後腹膜平滑筋肉腫例を報告した.平滑筋肉腫の特徴として局所浸潤性,局所再発性があり,その治療には集学的アプローチが必要であるRetroperitoneal leiomyosarcoma is often too large to be completely removed. We report a 67-year-old woman successfully treated with neoadjuvant CYVADIC (cyclosphosphamide, vincristine, adriamycin and dacarbazine). The tumor was removed with the right kidney and ureter and a part of the vena cava after 2 courses of CYVADIC. The tumor recurred at the duodenum 7 years later and was completely removed following neoadjuvant CYVADIC. Neoadjuvant chemotherapy could be helpful for the complete resection of advanced leiomyosarcoma.
