We report a case of pelvic osteosarcoma successfully treated with laparoscopic spacer placement and subsequent proton beam therapy. A 7-year-old girl underwent chemotherapy for osteosarcoma arising in the right ilium and was referred to our hospital for proton beam therapy. Because the intestine adjacent to the tumor was excluded from the radiation field, we performed laparoscopic spacer placement prior to proton beam therapy. Effective displacement of the intestine was achieved by the combined
