RESUMO
OBJECTIVE: Cancer patients are among the most vulnerable populations during and after a disaster. We evaluated the impact of treatment interruption on the survival of women with gynecologic cancer in Puerto Rico following hurricanes Irma and María. METHODS: Retrospective cohort study among a clinic-based sample of women diagnosed between January 2016-September 2017 (n=112). Women were followed up from their diagnosis until December 2019, to assess vital status. Kaplan-Meier survival curves and Cox proportional hazards models were performed. RESULTS: Mean age was 56 (±12.3) years; corpus uteri (58.9%) was the most common gynecologic cancer. Predominant treatments were surgery (91.1%) and chemotherapy (44.6%). Overall, 75.9% were receiving treatment before the hurricanes, 16.1% experienced treatment interruptions and 8.9% died during the follow-up period. Factors associated with treatment interruption in bivariate analysis included younger age (≤55 years), having regional/distant disease, and receiving >1 cancer treatment (p<0.05). Crude analysis revealed an increased risk of death among women with treatment interruption (HR: 3.88, 95% CI=1.09-13.77), persisting after adjusting for age and cancer stage (HR: 2.49, 95% CI= 0.69-9.01). CONCLUSIONS: Findings underscore the detrimental impact of treatment interruption on cancer survival in the aftermath of hurricanes, emphasizing the need for emergency response plans for this vulnerable population.
