Differences in toxicity across gender in patients treated with chemoradiation for rectal cancer.
The primary objective was to prospectively investigate the efficacy and toxicity of bolus 5-fluorouracil (5-FU) chemotherapy compared with the infusional 5-FU in combination with preoperative radiation in patients with locally advanced rectal cancer. Furthermore, in light of previous reports, toxicity profiles between men and women were also compared. Eighty-four consecutive patients with rectal adenocarcinoma were prospectively treated. There were no differences in tumour response, local recurrence or survival between bolus versus infusional groups or gender groups. In locally advanced rectal cancer, preoperative infusional chemotherapy combined with radiation was found to be less toxic than bolus chemotherapy and radiotherapy. Both regimens produced more toxic effects in women compared with men.
