The Chinese have been using local microwave induced intracorporeal [heat source is placed within the body] hyperthermia followed by immunotherapy to spare limbs while treating bone tumors. [57, 71, 72]  The Chinese have also treated patients with malignant bone tumor by intraoperative microwave heating of tumor bearing bone in place [to 50 deg C for 15 minutes], wide excision of tumor in soft tissue, and neoadjvant chemotherapy. [60] Healing [revascularization] of the tumor site could be demonstrated in a year or more. Pathological fracture however, can occur at devitalized bone.  [57, 71] The advantage of intraoperative microwave hyperthermia for bone tumors is that it keeps the shape and continuity of the bone, without osteotomy or internal fixation, and may benefit bone remodeling.  [60] The treatment is an alternative to replacement by prosthesis or allograft [graft to patient using patient's tissue] bridging techniques. [72]
