INCIDENCE, MORTALITY AND SURVIVAL OF ENDOMETRIAL CANCER IN MANIZALES, COLOMBIA 2003-2017

Abstract

Objective. To estimate the incidence, mortality and five-year survival of endometrial carcinoma in Manizales for the period 2003-2017. Materials and methods. Observational, retrospective, population-based study, descriptive in scope. Incidence and mortality rates were adjusted by the direct method using the Segi world population as reference. Passive and active follow-up of the cases was carried out until completing 60 months or until the follow-up closing date. Survival was estimated using Kaplan-Meier functions and Cox models. Results. 210 incident cases were observed in a population of 214.928 women. The average age at diagnosis was 61 years. The most frequent histological type was endometrioid, well differentiated. Most of the patients were affiliated to the contributory health insurance scheme and belonged to the middle socioeconomic level. The age-adjusted incidence rate was 5.7 new cases per 100,000 woman-years. Seventy-five deaths were identified, with greater mortality between 65-69 and 75-79 age groups. Overall survival was 95.1% at 12 months and 83.8% at 60 months. Statistically significant differences were found in survival in favor of epithelial histology, early stages at the time of diagnosis, and age at diagnosis less than 60 years. Conclusions: Manizales follows the global pattern of rise in the age-adjusted incidence rate. Mortality is like that reported in other countries in the region. In Manizales, endometrial cancer survival was higher in patients with early diagnosis, less than 60 years of age, and with endometrioid histology.
