[Intraoperative radiotherapy for local recurrence of intrapelvic malignancies].
From 1986 to 1992, seventeen patients with recurrent intrapelvic malignancies have been treated with intraoperative radiotherapy (IOR) in Saitama Cancer Center. They were 8 males and 9 females. The age ranged 44 to 83 (mean:61.6). The primary organs involved were rectum in 7, urinary bladder in 5, uterine cervix in 3 and ovary in 2. Invasion of recurrent disease into bony pelvis was noted in all but one patient. A total of 27 IORs were done on 18 occasions for 17 patients. The mean radiation dose was 25.6 Gy (range: 12-30). The cones used were 4 to 7 (mean: 5.4) cm in diameter. Debulking surgery was performed in 13 patients just before IOR. Chemotherapy and/or external radiotherapy were done in addition to IOR in most of the cases. As of May 1992, 14 patients had died with a mean survival time of 10 months (range:0.5-29.8). IOR seems to be useful in controlling the intrapelvic recurrent disease and may warrant further investigation.
