Research alerts transwomen to interpret commonplace prostate most cancers screening pointers with warning

UCSF-led examine alerts transwomen and physicians to interpret commonplace screening pointers with warning.

Transgender ladies on hormone remedy are inclined to skew artificially low on prostate most cancers screening exams, which can give false reassurance and delay prognosis and remedy, stories a brand new examine led by UC San Francisco.

The researchers discovered that transwomen scored 50 instances decrease than typical PSA exams (prostate-specific antigen), the gold commonplace device to detect prostate most cancers. This might imply that present “regular” thresholds are too excessive for transgender ladies, and their most cancers may not be discovered till a later stage, the investigators mentioned.

The examine seems June 26 in JAMA.

Transgender ladies preserve their prostates following gender-affirming surgical procedure which places them in danger for prostate most cancers. Typically, they’re on estrogen, the commonest gender-affirming hormone. However sufferers taking estrogen usually tend to present up of their physician’s places of work with high-grade prostate most cancers.

Sufferers and clinicians must be conscious that PSA values in transgender ladies on estrogen must be interpreted with warning, as they’re completely different than these in cisgender males.”

The prostate, a small gland that helps make semen, produces a protein known as prostate-specific antigen, or PSA. Blood ranges of PSA steadily are elevated in folks with prostate most cancers – and the PSA take a look at, which measures these ranges, is often used as a screening device. 

Within the new examine, investigators analyzed Veterans Well being Administration data between January 2000 and August 2023. Altogether, 210 sufferers who have been 40 and older, on estrogen and had no historical past of prostate most cancers have been included.

The researchers discovered that PSA ranges have been drastically decrease in transgender sufferers on estrogen and these sufferers may not get further screening till their PSA ranges rose, which may imply their cancers have been detected at a later stage.

At the moment, there are not any PSA ranges particular to transgender ladies. The researchers mentioned that additional work is required to find out the dangers and advantages of PSA screening amongst transgender ladies and to pinpoint best prostate most cancers screening practices for them.

“As increasingly more transwomen have applicable entry to gender-affirming care, it is important to not lose sight of long-term most cancers dangers in retained organs,” mentioned co-senior creator Matthew R. Cooperberg, MD, MPH, a UCSF urology professor and co-leader of the prostate most cancers program on the UCSF Helen Diller Household Complete Most cancers Middle.

“We’re simply beginning to perceive how estrogen and associated remedies modulate prostate most cancers danger, and the way to interpret PSA values on this inhabitants, so we will evolve a rational and evidence-based screening coverage,” he mentioned.
