By Your Powers Combined: Treating Pelvic Osteosarcoma With Combination Radiation and Thermoablation

A 77-year-old man with a history of diabetes, atrial fibrillation, heart failure with preserved ejection fraction, and class III obesity presented with 6 months of right groin pain. MRI showed a 10.5  × 6.9 × 12.1-cm tumor of the right pubis and ischium with soft-tissue extension involving the femoral acetabular joint, pelvic sidewall, obturator internus, adductor muscles, and abutting the prostate gland (Fig. 1). Core-needle biopsy confirmed a high-grade osteosarcoma. A positron emiss ion tomography/computed tomography scan demonstrated a fluorodeoxyglucose-avid lesion without distant metastases (stage III, T3bN0M0).
