RESUMO
OBJECTIVES: Cervical cancer incidence is rising in Puerto Rico (PR). Screening for cervical cancer could prevent the occurrence of the disease or lead to its early detection, translating to survival benefits. In this study, we evaluated the association of cervical cancer screening status with tumor diagnosis and survival among Hispanic women living in PR. METHODS: We analyzed data for 506 incident cases of primary cervical cancer diagnosed from the period 2011-2014, identified through the PR Central Cancer Registry. We ascertained screening status 3 years before cervical cancer diagnosis using data from the period 2008-2014 from the PR Central Cancer Registry-Health Insurance Linkage Database. Patients were followed until 2019. Our outcomes of interest were stage at diagnosis and survival. RESULTS: Most women (78.86%) were covered by public insurance (Medicare and/or Medicaid), and 69.57% underwent screening 3 years before their diagnosis. The proportion of cases diagnosed with localized stage was significantly greater among the screened group compared with those unscreened (43.5% vs 33.1%, p < .0001). Multivariate analysis showed that women insured through Medicaid were less likely to have been screened when compared with women with private insurance (odds ratio = 0.29; 95% CI = 0.16-0.52). Five-year survival was significantly greater among screened (72%) than unscreened (54%) women (p log-rank < 0.05). The multivariate Cox proportional hazards model showed that women who received screening had a 39% (hazard ratio [HR] = 0.61; 95% CI = 0.43-0.87) lower risk of death compared with unscreened women. CONCLUSION: Our findings exemplify survival benefits among women who underwent cervical cancer screening in PR. Interventions to improve screening uptake and adherence are a public health priority.
