Radiation therapy for superficial inguinal lymph node metastases from ovarian clear cell carcinoma and associated inguinal hernia

Inguinal lymph node metastases (LNMs) from ovarian cancer (OC) are uncommon. Lymphangiogram and autopsy studies reportedly show that overall, approximately 3% of metastases from OC affect inguinal lymph nodes, and of these, 5% of inguinal LNMs are from the ovaries (1-3). The standard treatment for OC is cytoreductive surgery. Although superficial inguinal lymph node (SILN) metastases from OC are classified as distant, their treatment outcomes are better than those of distant metastases to other lymph nodes or organs; their control is therefore critical (4). To our knowledge, no reports regarding radiation therapy for SILN metastases from OC are available
