Survival of patients with cancers of the female genital organs in Poland, 2000–2019

Abstract

AbstractThe purpose of this study was to estimate cancer survival in Poland between 2000 and 2019 for malignant neoplasms of female genital organs (FGO). We calculated survival in cancer of vulva, vagina, cervix uteri, corpus uteri, ovary, and other unspecified female genital organs. Data were obtained from the Polish National Cancer Registry. We estimated age-standardized 5- and 10-year net survival (NS) with the life table method and the Pohar-Perme estimator using the International Cancer Survival Standard weights. Overall, 231,925 FGO cancer cases were included in the study. The overall FGO age-standardized 5-year NS was 58.2% (95% confidence interval (CI) 57.9–58.5%) and the 10-year NS 51.5% (51.5–52.3%). Between 2000 and 2004 and 2015–2018, the highest statistically significant increase in age-standardized 5-year survival was noted for ovarian cancer at + 5.6% (P < 0.001). The FGO cancer median survival time was 8.8 years (8.6–8.9 years), with a standardized mortality rate of 6.1 (6.0–6.1), and with cause-specific years of life lost at 7.8 years (7.7–7.8 years). Hazard ratios (HR) increased with age at diagnosis (HR = 1.02, 95% CI 1.01–1.03, P = 0.001). Although FGO cancer survivorship has been consistently improving during the last twenty years, additional efforts need to be undertaken to improve survivorship in several FGO cancers.
