PURPOSE   Radical external-beam radiotherapy (EBRT) followed by intracavitary brachytherapy is standard of care for patients with localized carcinoma of the cervix unsuitable for radical surgery. However, outcome data are scarce in resource-limited settings. We conducted a retrospective analysis of survival in a cohort of patients treated with this strategy in Sri Lanka.PATIENTS AND METHODS   All patients with localized cervical cancer treated with primary EBRT and intracavitary brachytherapy from 2014 to 2015 were included in the study. Primary end point was disease-free survival (DFS), defined as time to local or systemic recurrence or death. Univariable analysis was performed to determine the prognostic significance of the following variables: age, stage, use of concurrent chemotherapy, EBRT dose, brachytherapy dose, and time to completion of treatment (dichotomized at 60 days). Factors significant on univariable analysis were included in a multivariable model.RESULTS   A total of 113 patients with available data were included in the analysis. Mean age was 58 years (range, 35-85 years), and most patients (n = 103 of 113) presented with stage ≥ IIB disease. Median time to delivery of brachytherapy from commencement of EBRT was 110 days (range, 34-215 days), with only 12 (11%) of 113 patients completing treatment within 60 days. Median follow-up was 28 months (range, 5-60 months), and 2-year DFS was 63.7% (95% CI, 55.4% to 73.2%). Treatment delay was the only significant factor associated with inferior DFS on univariable analysis (log-rank P = .03), and therefore, multivariable analysis was not performed.CONCLUSION   There are significant delays in receiving intracavitary brachytherapy after completing EBRT for cervical cancer in Sri Lanka, which is associated with inferior DFS. Increasing brachytherapy resources is an urgent priority to improve outcomes of patients with cervical cancer.
