RESUMEN
Comparative estimation of immediate and late follow-up results of treatment was con- ducted in 520 patients, suffering cancer of the colonic right half, including coecum - in 227 (43.7% ± 2.1%), colon ascendum - in 159(30.7% ± 2.0%), right colonic flexure - in 66 (12.9% ± 1.3%), right half of colon transversum - in 66 (12.9% ± 4.2%). In 463 (89.0% ± 1.4%) patients radical operations were performed, while in 57 (11.0% ± 1.7%) - the symptomatic. After radical operations 8 (1.7% ± 0.5%) patients died, and after the symptomatic - 3 (5.3% ± 3.0%). Definite surgical treatment was performed in 258 (60,8% ± 2,4%) patients, the combined one - in 166 (39.2% ± 2.4%). Five-year survival have constituted (64.2% ± 5.5%) for the patients, operated on for the colon ascendumcancer, and (19.1% ± 5.7%) - for cancer of right colonic flexure; while after combined treatment - (40.4% ± 5.8%) in patients, operated on for cancer of coecum, (29.4% ± 11.9%) - right half of colon transversum; ten-year survival have constituted (16.8% ± 2.7%) for the patients, who were radically operated for cancer of coecum, and (4.8% ± 2.6%) - for cancer of right colonic flexure (p<0,005). Late follow-up results of radical treatment of the colonic right half depends essentially on localization and degree of the cancer spread.
