Background
We examined ethnic differences in age-standardised net survival (ANS) for eight common cancers diagnosed in England between 2010 and 2019.
Methods
Analyses included 247,428 patients aged ≥40 years diagnosed with breast, prostate, lung, colorectal, cervical, ovarian, myeloma, and oesophagogastric cancers. Net survival was estimated at one, three, and five years using the Pohar-Perme estimator and age-standardised with International Cancer Survival Standards weights across four age bands.
Results
Compared with White patients, Black patients had higher ANS for lung and prostate cancers at all time points, for myeloma at one year, and for oesophagogastric cancer at one and three years. However, they had lower ANS for breast cancer at three years. Asian patients had higher ANS for lung, prostate, and oesophagogastric cancers at all time points, and for other sites at varying follow-up times. Patients in the Mixed group had higher ANS for most cancers, whereas those in the Other ethnic group generally had lower ANS compared with White patients.
Conclusions
Ethnic minority groups in England do not consistently experience poorer cancer survival, with varying patterns observed by cancer site. Universal healthcare access may reduce disparities observed elsewhere, highlighting the importance of context-specific research and public policy.
