Impact of management on mortality in patients with invasive cervical cancer in Reunion Island

Objective: In Reunion Island, the standardized mortality rate for cervical cancer is 4.8/100,000 women, twice higher than in Metropolitan France. For locally advanced disease, the standard of care includes a treatment by brachytherapy. Nevertheless, brachytherapy was not available on the Island before 2016. The objective of this study was to assess the impact of the management of patients with invasive cervical cancer on mortality in Reunion. Methods: We have identified all the women hospitalized in one of the health care centers of the Island diagnosed with invasive cervical cancer between 01/01/2010 and 31/12/2015. The guidelines of the French Society of Gynecological Oncology (FSGO) were considered as the reference to evaluate professional practices. The characteristics that had an influence on global survival after log-rank test were included in a multivariate analysis according to the Cox Model. Results: Retrospective analysis identified 303 women meeting inclusion criteria. The assessment of professional practices showed that the decisions on 11.6% of the patients discussed during multidisciplinary meetings, were not applied, consequentially leading to a decrease in survival (p = 0.001). A total of 156 patients (51.5%) were administered a treatment in accordance with the guidelines of the FSGO and had a better survival, even after multivariate analysis (HR 2.53 [CI 95% 1.55-4.14], p < 10(-3)). Nonconformity was associated with the lack of access to brachytherapy on the Island. Women on the Island presented low rates of screening tests (cover rates 53.2%). Conclusion: The absence of treatment in accordance with the guidelines and decisions taken during multidisciplinary meetings and the absence of brachytherapy were associated to a higher mortality among patients with invasive cervical cancer in Reunion Island. We hope that the implementation of brachytherapy in Reunion will address these deficiencies. (C) 2017 Elsevier B.V. All rights reserved.
