Keywords:Uterine Cervical Neoplasms, Survival Analysis, Survival Rate, Epidemiology, Information Systems
Objective: to estimate specific five-year survival in women diagnosed with cervical cancer living in the municipalities of Cuiabá and Várzea Grande, Mato Grosso, Brazil. Methods: Retrospective cohort study with information from the Cuiabá Population-Based Cancer Registry and the Mortality Information System. To estimate the probability of specific survival in five years, the Kaplan-Meier estimator and the log-rank test were used with the purpose of verifying if there are statistical differences in the lifetime by groups. To verify the proportionality of the failure rates, the Schoenfeld residual test was used according to the statistical significance level of 0.05. Results: Specific five-year survival and median time were 90.0% and 50.3 months, respectively for cervical cancer. When analyzing by age, the highest specific survival was among women aged 20 to 49 years (91.7%) and median time was 53.3 months. For the histological type, the highest specific survival was among women with adenocarcinoma (92.3%) and the mean survival time was 53.5 months. Conclusions: This study showed that specific survival after 5 years of diagnosis remained around 90% in patients with cervical cancer. Patients aged 20 to 49 years had higher specific survival and was statistically significant difference only between age groups.
