Purpose:
Prostate cancer in gay, bisexual, and other men who have sex
with men (GBM) is an emerging medical and public health concern. The purpose of
this review is to summarize the literature on prostate cancer in GBM, including
its epidemiology, clinical studies, and anecdotal reports.
Methods:
In 2015, we undertook a structured literature review of all
studies from 2000 to 2015.
Results:
Despite prostate cancer being the most common cancer in GBM,
the main finding of this review is that prostate cancer in GBM is very
under-researched. With only 30 published articles in English (a rate of 1.9
articles per year), most of the literature is limited to case studies or
anecdotal reports. There is some evidence of a link between human
immunodeficiency virus (HIV)-positive status and prostate cancer, with early
studies showing HIV infection as a risk factor and more recent studies as it
being protective. Antiretroviral treatment appears protective. Globally, only
four quantitative studies have been published. Based on this admittedly limited
literature, GBM appear to be screened for prostate cancer less than other men
and are diagnosed with prostate cancer at about the same rate, but have poorer
sexual function and quality-of-life outcomes.
Conclusion:
Methodological challenges to advancing research include
challenges in subject identification, recruitment, heterocentric definitions of
dysfunction based on vaginal intercourse and penetrative sex, and inappropriate
measures. Six future directions, to advance the study of the effects of
prostate cancer in GBM and to improve treatment, are detailed...
[H]eterocentric definitions of functioning limited to
penetrative sex are problematic. While DSM-5115 defines
“sexual dysfunction” as “a clinically significant disturbance in a person's
ability to respond sexually,” erectile functioning in prostate cancer treatment
is typically operationalized as “sufficient for vaginal penetration.”5,116,117 This
gold standard is irrelevant for sex between men. Physiologically, anal
penetration requires a greater degree of penile rigidity than vaginal
penetration,28,30 which
potentially explains the poorer outcomes of prostate cancer treatment for GBM.
Population-appropriate measures and definitions need to be developed before the
effects of prostate cancer treatment in GBM can be enumerated.
Six directions for future research are identified.
First, methodological research is needed to identify ways to locate, recruit,
and retain GBM with prostate cancer in studies and to develop
population-appropriate definitions and measures. Second, more formative
research is needed. In particular, in-depth examination of the effects of
treatment on sexual functioning behavior and identities will advance a
comprehensive sexological understanding of the experience of prostate cancer in
GBM. Third, empirical studies to quantify the prevalence and incidence of
sexual problems and effects of treatment by treatment type will be critical to
informing clinical care. Fourth, comparative studies of treatment preferences
for GBM and heterosexual men should confirm whether GBM are more, as, or less
likely than heterosexuals to choose surgical intervention. Fifth, intervention
studies to address the rehabilitation needs of GBM with prostate cancer are
needed to develop evidence-based interventions tailored for this population.
Finally, the training needs of urologists, surgeons, oncologists, and other
specialists providing services to GBM with prostate cancer need to be
identified and curricula developed to ensure culturally competent providers
capable of addressing the sexual health needs and care of this population...
