Abstrakt: Overall 5-year survival and factors associated with death were evaluated in a cohort of 342 women with cervical cancer referred to radiotherapy in the Baixada Fluminense, in Greater Metropolitan Rio de Janeiro State, Brazil. Overall 5-year survival was 25.3%, reaching 60.8% in women with stage IIA or less. The model adjusted by extended Cox proportional regression showed an increase in mortality risk for patients with stages IIB-IIIB (HR = 1.89; 95%CI: 1.214; 2.957) and IVA-IVB (HR = 5.78; 95%CI: 2.973; 11.265). Cytology in asymptomatic women (HR = 0.58; 95%CI: 0.362; 0.961) and referral for first consultation in an oncology service in the Baixada Fluminense (HR = 0.60; 95%CI: 0.418; 0.875) were the main protective factors identified by the study. Waiting time (> 60 versus ≤ 60 days) was not statistically significant, but a delay of 4 days worsened the outcome. The 60-day limit for initiating radiotherapy should be respected, because delay greater than 64 days showed a significant association between all waiting time cut-off points and 5-year mortality risk.
