ABSTRACT
Objective To explore clinical indications and curative effects of microwave coagulation combined with submucous 5-fluorouracil (5-FU) injection in the management of early-stage lower rectal cancer. Methods Nine patients with early-stage lower rectal cancer underwent microwave coagulation with submucous 5-FU injection from January 1996 to December 2002. After the microwave treatment, a retention enteroclysis with 100~200 ml normal saline containing 1.0 g 5-FU was performed once daily for 3 days. Results In 3 patients, levels of carcinoembryonic antigen (CEA), which were preoperatively increased, were reduced below normal limits after microwave treatment. No hemorrhage or other intra- or post-operative complications was observed. Follow-up observations to January 2006 showed that all the 9 patients survived. One patient survived for 3 years and 5 months, 1 patient survived for 3 years and 8 months, and 1 patient experienced a tumor relapse at 1 year and 4 months and survived for 2 years and 9 months after a Miles procedure. Among 6 patients who survived longer than 5 years, 1 survived for 5 years and 1 month, 1 for 6 years and 3 months, 1 for 6 years and 8 months, 1 for 7 years and 6 months, and 2 for 9 years. Conclusions Surgical indications for microwave coagulation combined with submucous 5-FU injection for rectal cancer included early-stage cancer, lesions located within 7 cm away from the anus, the mass type cancer, tumor diameter at 0.5~3.0 cm or less than one third of the rectum’s circumference, well differentiated tumor, and patient’s strong anus-sparing demand. This method is minimally invasive, safe, reliable, and cost-effective.
