Use of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Pediatric Sarcoma for Maximal Oncologic Control.

Few centers worldwide have trialed cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in pediatric rhabdomyosarcoma. This case involves a 5-year-old boy with gross hematuria who was found to have an 8 cm pelvic mass, likely arising from the prostate and extending along the bladder wall. Excisional biopsy revealed undifferentiated fusion negative sarcoma. The mass demonstrated reduction in size with chemotherapy and photon radiation therapy. He presented to our institution for delayed primary excision, and underwent cytoreductive surgery with hyperthermic intraperitoneal chemotherapy using cisplatin. Follow-up imaging 15 months postoperatively demonstrates no evidence of disease.
