Resectability of rectal cancers still fixed after radio-chemotherapy: evaluation by digital rectal examination, MRI, and intraoperative examination.
Eighteen patients with primary fixed rectal cancer as judged by digital rectal examination (DRE) were included. They all had radiation therapy with 60 Gy in 30 fractions combined with oral UFT and Isovorin. All patients were evaluated by DRE and magnetic resonance imaging (MRI) before and after treatment. After 5-7 weeks, eight tumors were mobile on DRE. All eight patients had an R0 resection. Of the remaining ten patients with fixed rectal cancer, eight had an R0 resection. One patient had an R1 resection and one patient was not operated. Intraoperative bimanual rectal examination was performed with one finger through the anus and one hand in the rectovaginal/rectovesical fossa before resection was performed. After chemo-radiation DRE correctly predicted the tumor to be advanced or not in 12/17 patients, MRI in 14/17, and bimanual rectal examination in 17/17 patients.
