Cabasag CJ, Butler J, Arnold M, et al. - Utilizing data from ovarian cancer patients (n = 58,161) from 21 population-based cancer registries, researchers assessed the disparities in ovarian cancer survival by age and stage at diagnosis within and across seven high-income countries, including Australia, Canada, Denmark, Ireland, New Zealand, Norway, and United Kingdom. They compared 1-year and 3-year age- and stage-specific net survival (NS) between countries. The range of 3-year all-ages NS was from 45 to 57%; the highest survival was reported in Australia (56%) and Norway (57%). Those women aged 65–74 and 75–99 years demonstrated the highest proportion with ‘distant’ stage, and there was a marked difference in the proportion of women with ‘distant’ stage between countries. The lowest 3-year age-specific survival (20–34%) was reported in the oldest age group, and the widest difference was seen among women aged 65–74 across countries. The existence of international disparities in ovarian cancer survival by stage was revealed in this study, with the largest variations noted in the oldest age group having advanced disease.
