[Locally disseminated cancer of the sigmoid colon]

The study discusses the experience of treatment of 207 patients with locally-advanced cancer of the sigmoid colon who made up 13.5% of the total number of cases of cancer of this site seen in the clinic in 1972-1990. Radical surgery was performed in 170 (82.1%) patients. Postoperative lethality rate was 5.8%, five-year survival rate--70.5 +/- 5.6%. The use of adjuvant preoperative radiotherapy assured a higher resection rate and had no adverse effect on immediate results.
