Riassunto:Uruguay shares with Argentina the dubious honour ofbeing the only South Amercan countries with a highincidence of colorectal cancer. The present study is thefirst population-based study of co/orectal cancer inMontevideo. Through multiple--access searching strategy,ali new cases of colorectal cancer diagnosed ininhabitants of Montevideo during 1991 were carefullyregistered, in arder to achieve a proper knowledge aboutincidence, clinical presentation, diagnostic methods,treatment and clinico--pathologica/ staging. 554 patientswith newly diagnosed adenocarcinomas of thecolorectum were identified, with a male-femalerelationship of 1:1,07 and an average age of 69 years.24% presented as an emergency, mainly as intestinalobstruction. 63% were colonic tumours (49% in rightcolon and 51% in left colon) and 37% were rectaltumours. Syncronic hepatic metastasis were found in16,8%, isolated perifonea/ carcinomatosis in 5,4% andextension of /he tumour to adyacent structures in 13,9%.527 patients were operated (95,2%) with postoperativemortality of 11,8%, and resection of /he tumour was donein 475 patients (a resecability rate of 86%) with a 10,8%postresection mortality. 3,4% of the coloree/al cancerswere metachronous and 1,9 synchronous. Analysis ofthese data revealed: 1) that registering methodology wasbasically appropiate; 2) that the main clinical andpathological traits of coloree/al cancer in Montevideo arenot different from /hose resulting of o/her populationbased on large unselected series in North America,Australia or Western Europe.
