To understand the impact of demographic, behavioral and contextual factors on cervical cancer, we examined the profile of women classified according to cervical cancer staging [precursor lesions cervical intraephitelial neoplasia (CIN2/CIN3), early- and advanced-stage cancer]. Patients were identified in the main oncological reference hospital in Pará State, Brazil, from 2013 through 2015. Adjusted prevalence ratios and their respective 95% confidence intervals were estimated using Poisson regression with robust variance. The study included 172 cases of CIN2/CIN3 lesions, 158 of early stage and 552 of advanced stage of cervical cancer. The proportion of gynecological complaints as a reason for clinic visit was 2.3 times higher among patients at an early stage compared with patients with CIN2/CIN3 lesions. Compared with early-stage cancer groups, the prevalence of advanced-stage cancer was higher among older patients, those without paid activity (adjusted prevalence ratio = 1.15; confidence interval 95%: 1.03-1.29), those who never had a Pap test (adjusted prevalence ratio = 1.23; confidence interval 95%: 1.08-1.40), those who were seen at the hospital clinic due to gynecological complaints (adjusted prevalence ratio = 1.48; confidence interval 95%: 1.19-1.85) and those who underwent biopsy in the private care system (adjusted prevalence ratio = 1.12; confidence interval 95%: 1.02-1.22). These differences seem to reflect problems in the health system, low socioeconomic level and poor awareness of the importance of Pap tests among those with a diagnosis of advanced-stage cervical cancer.
