Colorectal cancer A prospective baseline study population in the city of Montevideo: Preliminary results of the incidence study
Cáncer colorrectal Un estudio prospectivo de base poblacional en la ciudad de Montevideo: Resultados preliminares del estudio de incidencia
Resumen:
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.
Uruguay comparte con Argentina el dudoso honor de serlos únicos países latinoamericanos con alta mortalidadpor cáncer colorrectal. El presente trabajo es el primerestudio de base poblacional del cáncer colorrectal en laciudad de Montevideo. A través de una estrategia deaccesos múltiples cuidadosamente diseñada, todos losnuevos casos de cáncer colorrectal diagnosticados enpobladores habituales del departamento de Montevideoen 1991 fueron registrados, con el fin de lograr unconocimiento adecuado acerca de la incidencia,características clínicas, métodos diagnósticos yterapéuticos y estadificación anátomo patológica de laenfermedad. Se identificaron 554 pacientes, con unarelación masculina/femenina de 1:1,07 y una edadpromedio de 69 años. De ellos 24% se presentaronclínicamente como casos de emergencia, 63% estabanlocalizados en el colon (49% en el colon derecho y 51 %en el colon izquierdo) y 37% en el recto. Se encontraronmetástasis hepáticas sincrónicas en 16,8%,carcinomatosis perineal aislada en 5,4% y extensión deltumor a estructuras vecinas en 13,9%. 527 pacientesfueron operados (95,2%) con una mortalidad operatoriade 11,8% y el tumor fue ,esecado en 475 (tasa deresecabilidad de 86%) con una mortalidad posresecciónde 10,8%. El análisis de los datos obtenidos permite: 1)confirmar la adecuada metodología utilizada en elregistro que asegura la exhaustividad de los datosobtenj¡jos; 2) afirmar que los parámetros principales de la enfermedad no presentan diferencias sustantivas conlos propios de series poblacionales no seleccionadas delos países desarrollados.
