Experience with curative radiotherapy for cervix cancer in the Bahamas for 2006-2016

Cervix cancer is a significant health problem. As access to quality care in Small Island Developing States improves, and cancer centers become established, providers of care can summarize local experience to benchmark system quality and look for ways to further improve value.

This is a retrospective study of all cases of cervix cancer managed 2006-2016 at The Cancer Centre Bahamas, in conjunction with Princess Margaret Hospital, Nassau, affiliated with The University of West Indies. Seventy-two women received curative radiotherapy or chemoradiotherapy. Herein are reported presenting characteristics, treatments, waiting and overall treatment times, plus outcomes of recurrence, survival, and adverse events.

For 68 newly diagnosed cases, median waiting time (diagnosis to commencing treatment) was 110 days. It was 90 days for those 47 cases who had no prior surgery or neoadjuvant chemotherapy. Overall, 99% of intended external radiotherapy fractions, 74% of brachytherapy sessions, and 79% of concurrent weekly chemotherapy were administered. For all 72 cases, median overall treatment time was 63 days; and for the 47 case sub-group, it was 78 days during 2006-2010 and 65 days during 2011-2016 (p = 0.005), so improving over calendar time. Four cases experienced grade 3-4 toxicities. Twelve had urological complications from disease or treatment. Five cases experienced local failure; eight experienced distant failure. Newly diagnosed stage 2B (26/72) had a 2-year survival of 71%.

This report demonstrates the impact of providing curative radiation-based treatments for cervical cancer in a small state. It suggests ways to further improve operations and justifies additional research.
