Conclusion:

These results show that overall survival of men treated with radiotherapy at a single institution was similar across men of known ethnicities. However, men who did not state their ethnicity had significantly worse survival than those who disclosed ethnicity.

Overall survival for men with missing ethnicity data showed no significant difference compared to men with recorded ethnicity, suggesting that missing data was not acting as a surrogate for survival.

A reluctance to disclose ethnicity could be a surrogate for socioeconomic deprivation, which is known to be associated with poorer outcomes, or lack of patient engagement caused by language barriers and lack of trust of the health care system 1 – 3 . This should be investigated further to take steps to mitigate. Further, a high proportion (64.5%) of men who preferred not to say their ethnicity were treated with a brachytherapy boost. A recent study reported that dose outside the prostate was associated with treatment outcome for high-risk men treated in this way 7 . Given our results, that suggest choosing not to disclose ethnicity is associated with prognosis, confounding variables should also be investigated, for example and socioeconomic status (via post-code data), to determine whether these interact with treatment characteristics, such as dose in the prostate and seminal vesicles.
