Abstract
BACKGROUND: Ovarian cancer survival in low- and middle-income countries is lower than in high-income countries, due to disparities in healthcare access and socioeconomic factors. This study aimed to describe trends in ovarian cancer survival in Sergipe, Northeast Brazil, by histological group. METHODS: We analysed data on 948 women aged 15-99 years diagnosed with a cancer of the ovary between 1996 and 2017, in Sergipe, Brazil. One- and five-year net survival were estimated by histological group and calendar periods of diagnosis (1996-1999, 2000-2004, 2005-2009, 2010-2014, 2015-2017) using the Pohar-Perme estimator. Survival estimates were age-standardised using International Cancer Survival Standard weights. RESULTS: Between 1996 and 2017, one-year and five-year net survival for ovarian cancer were 63.4 % and 37.4 %, respectively. Five-year net survival trends increased from 30.9 % (2000-2004) to 46.8 % (2015-2017). Epithelial type I tumours comprised roughly a quarter of cases, while type II tumours constituted over half. Both types exhibited similar one-year survival, ranging from 67 % to 68.5 % during 1996-2017. However, five-year net survival for type II tumours was remarkably lower at 32.5 %, compared to 52 % for type I tumours. CONCLUSION: Despite a minor improvement in five-year net survival over the 22 years, survival for women with ovarian cancer remains unfavourable, particularly for those diagnosed with Type II epithelial tumours, which have remarkably lower five-year survival than Type I.
