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.

巴西东北部一个州卵巢癌净生存趋势（1996-2017）。

背景：由于医疗保健可及性和社会经济因素方面的差异，低收入和中等收入国家的卵巢癌生存率低于高收入国家。本研究旨在通过组织学分组描述巴西东北部Sergipe地区卵巢癌生存率的趋势。方法：我们分析了1996年至2017年间巴西Sergipe 948名15-99岁被诊断患有卵巢癌的女性的数据。使用Pohar-Perme估计器，按组织学组和日历诊断期（1996-1999、2000-2004、2005-2009、2010-2014、2015-2017）估计1年和5年净生存率。生存估计使用国际癌症生存标准权重进行年龄标准化。结果：1996年至2017年，卵巢癌的1年和5年净生存率分别为63.4 %和37.4 %。5年净生存趋势从30.9% %（2000-2004年）增加到46.8% %（2015-2017年）。上皮I型肿瘤约占病例的四分之一，而II型肿瘤占一半以上。1996-2017年，两种类型的一年生存率相似，从67 %到68.5 %不等。然而，II型肿瘤的5年净生存率为32.5% %，而I型肿瘤的5年净生存率为52% %。结论：尽管22年的5年净生存率略有改善，但卵巢癌妇女的生存率仍然不利，特别是那些被诊断为II型上皮肿瘤的妇女，其5年生存率明显低于I型。
