Abstract
Four patients who had a metastatic tumor in the pelvis were treated with a combination of external irradiation of 20-30 Gy and intraoperative irradiation of 15-20 Gy. Intraoperative irradiation was done using Liniac electron beams (Mevatron 77DX67, Siemens Co., Ltd.) during surgery which retracted the bowels out of the radiation field.
Severe hip pain disappeared in all the patients after the radiotherapy. A follow-up study by radiography disclosed findings indicating the effectiveness, such as perifocal sclerosis of the lesion and interruption of the progress of bone destruction, in three patients. No patients complained of radiation complications of the bowels.
So, it seems that a combination of external and intraoperative irradiation was useful for the treatment of metastatic tumors in the pelvis.
