Military service and health-related quality of life among gay and bisexual prostate cancer survivors: Results from the Restore -2 study.

INTRODUCTION: There are notable disparities in health-related quality of life (HRQOL) between gay and bisexual men (GBM) and heterosexual patients with prostate cancer (PCa); however, the role of past military service is unclear. This study examines HRQOL differences in GBM PCa survivors based on reported military service history. METHODS: We used data from the 24-month follow-up survey of the Restore-2 study, a clinical trial which evaluated a rehabilitation programme for GBM PCa survivors. PCa HRQOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC-50) and the Functional Assessment of Cancer Treatment-Prostate (FACT-P). Mental health quality of life was assessed using the Brief Symptom Inventory-18 (BSI-18) scale, while sexual functioning was measured using the Sexual Minorities and Prostate Cancer Scale (SMACS). Multivariable linear regression was used to estimate unadjusted and adjusted mean differences in HRQOL between GBM with and without a reported history of military service. RESULTS: In this cross-sectional study of 351 GBM PCa survivors, 47 (13.4%) reported a history of US military service. After adjusting for covariates, participants who reported a history of military service (compared with those with no military service) had clinically better scores on the FACT-P physical, social and emotional well-being domains, as well as higher total FACT-General, EPIC urinary bother and hormonal function scores. Additionally, men with a history of military service reported significantly fewer sexual problems, more sexual confidence and less urinary incontinence in sex. CONCLUSION: This exploratory study provides the first evidence that GBM PCa survivors with a military background may have clinically better outcomes than those without military service. Potential reasons may include the structured support and healthcare access associated with military service, fostering resilience and well-being. These findings underscore the need for further research to elucidate how military service influences PCa HRQOL.

Discrimination of Sexual and Gender Minority Patients in Prostate Cancer Treatment: Results from the Restore-1 Study.

This study is the first to quantify experiences of discrimination in treatment undertaken by sexual and gender minority prostate cancer patients. Participants were 192 gay and bisexual and one transgender prostate cancer patients living in the US recruited from North America's largest online cancer support group. In this online survey, discrimination in treatment was measured using the Everyday Discrimination Scale (EDS), adapted for medical settings. Almost half (46%) endorsed at least one item, including 43% that the provider did not listen, 25% that they were talked down to, 20% that they received poorer care than other patients, 19% that the provider acted as superior, and 10% that the provider appeared afraid of them. While most (26.3%) rated the discrimination as "rare" or "sometimes" (EDS=1-3), 20% reported it as more common (EDS≥4). Most attributed the discrimination to their sexual orientation, or to providers being arrogant or too pushed for time. Discrimination was significantly associated with poorer urinary, bowel, and hormonal (but not sexual) EPIC function and bother scores, and with poorer mental health (SF-12). Those who had systemic/combined treatment (versus either radiation only or surgery only) were more likely to report discrimination. This study provides the first evidence that discrimination in prostate cancer treatment, including micro-aggressions, appear a common experience for gay and bisexual patients, and may result in poorer health outcomes.

Unrecognized sexual dysfunction in gay and bisexual men after prostate cancer treatment: the antecedents and impact of anodyspareunia.

BACKGROUND: Anodyspareunia may be an adverse outcome of prostate cancer (PCa) treatment for gay, bisexual, and other men who have sex with men (GBM). AIM: The aims of this study were to (1) describe the clinical symptoms of painful receptive anal intercourse (RAI) in GBM following PCa treatment, (2) estimate the prevalence of anodyspareunia, and (3) identify clinical and psychosocial correlates. METHODS: This was a secondary analysis of baseline and 24-month follow-up data from the Restore-2 randomized clinical trial of 401 GBM treated for PCa. The analytic sample included only those participants who attempted RAI during or since their PCa treatment (N = 195). OUTCOMES: Anodyspareunia was operationalized as moderate to severe pain during RAI for ≥6 months that resulted in mild to severe distress. Additional quality-of-life outcomes included the Expanded Prostate Cancer Index Composite (bowel function and bother subscales), the Brief Symptom Inventory-18, and the Functional Assessment of Cancer Therapy-Prostate. RESULTS: Overall 82 (42.1%) participants reported pain during RAI since completing PCa treatment. Of these, 45.1% experienced painful RAI sometimes or frequently, and 63.0% indicated that the pain was persistent. The pain at its worst was moderate to very severe for 79.0%. The experience of pain was at least mildly distressing for 63.5%. Painful RAI worsened for a third (33.4%) of participants after completing PCa treatment. Of the 82 GBM, 15.4% were classified as meeting criteria for anodyspareunia. Antecedents of anodyspareunia included a lifelong history of painful RAI and bowel dysfunction following PCa treatment. Those reporting symptoms of anodyspareunia were more likely to avoid RAI due to pain (adjusted odds ratio, 4.37), which was negatively associated with sexual satisfaction (mean difference, -2.77) and self-esteem (mean difference, -3.33). The model explained 37.2% of the variance in overall quality of life. CLINICAL IMPLICATIONS: Culturally responsive PCa care should include the assessment of anodyspareunia among GBM and explore treatment options. STRENGTHS AND LIMITATIONS: This is the largest study to date focused on anodyspareunia among GBM treated for PCa. Anodyspareunia was assessed with multiple items characterizing the intensity, duration, and distress related to painful RAI. The external validity of the findings is limited by the nonprobability sample. Furthermore, the cause-and-effect relationships between the reported associations cannot be established by the research design. CONCLUSIONS: Anodyspareunia should be considered a sexual dysfunction in GBM and investigated as an adverse outcome of PCa treatment.

The Effects of Prostate Cancer Treatment on Role-In-Sex in Gay and Bisexual Men: Mixed Methods Results from the Restore-1 and Restore-2 Studies.

Gay and bisexual men (GBM) with prostate cancer experience worse sexual and mental health outcomes following prostate cancer treatment than heterosexual men. Emerging evidence suggests that GBM may change their role-in-sex in response to treatment effects. The purpose of this study was to describe the impact of prostate cancer treatment on role-in-sex, to estimate the prevalence of such changes, and to determine the impact on quality of life and mental health. We conducted semi-structured interviews with 30 sexual minority prostate cancer patients. Then, we recruited 401 gay and bisexual prostate cancer patients into a study assessing the effects of rehabilitation. Qualitative data were analyzed using descriptive thematic analysis. Differences in quality of life and mental health outcomes were analyzed using multivariate analyses of variance. Prostate cancer treatment resulted in loss of role-in-sex for many patients. When changes in role-in-sex occurred, the shifts were predominantly from tops to bottoms. Those with a current top role-in-sex had significantly better sexual and mental health outcomes than either versatiles or bottoms. Clinical implications include the need for providers to ask about role-in-sex in order to address disparities in health outcomes by sexual orientation and to provide culturally appropriate care to sexual minority patients.

Prevalence and Risk Factors for Sexually Transmitted Infections in Gay and Bisexual Prostate Cancer Survivors: Results From the Restore-2 Study.

Background: Equitable cancer survivorship care for gay and bisexual male (GBM) prostate cancer survivors should be responsive to their sexual health needs. Rates of sexually transmitted infections (STIs) are higher among GBM compared to heterosexual men across the lifespan. In addition, evidence suggests that GBM will use a variety of strategies to cope with sexual dysfunction that may increase risk for STIs. The purpose of this study was to determine the prevalence of STIs following prostate cancer treatment among GBM and identify risk factors. Methods: In 2019, 401 GBM previously treated for prostate cancer were recruited into the Restore-2 Study. They completed a baseline online questionnaire with items assessing STIs diagnosed since being treated for prostate cancer. Any STI diagnoses was regressed on demographic, clinical, and relationship related variables using binary logistic regression. Results: Forty-five participants (11.4%) were diagnosed with an STI during or following their prostate cancer treatment. The mostly commonly diagnosed STI was syphilis (4.3%), followed by gonorrhoea (2.8%), and chlamydia (2.5%). Four participants were infected with HIV following their prostate cancer treatment. Independent risk factors for STI diagnosis included time since prostate cancer diagnosis (aOR = 1.18; 95% CI: 1.10-1.26), nonmonogamous sexual relationship (aOR = 11.23; 95% CI: 2.11-59.73), better sexual function (aOR = 1.02; 95% CI: 1.01-1.04), penile injection treatment (aOR = 3.28; 95% CI: 1.48-7.29), and multiple sex partners (aOR = 5.57; 95% CI: 1.64-18.96). Conclusions: GBM prostate cancer survivors are at risk for STIs. Culturally responsive STI prevention should be incorporated into cancer survivorship plans, particularly as men are treated for and regain sexual function over time.

Racial/Ethnic Differences in Health-Related Quality of Life Among Gay and Bisexual Prostate Cancer Survivors.

Introduction: Prostate cancer treatment has established effects on the health-related quality of life (HRQOL) of patients. While racial/ethnic differences in HRQOL have been explored in heterosexual patients, this is the first study to examine racial/ethnic differences in a cohort of sexual minority prostate cancer survivors. Methods: We used data from the Restore-1 study, an online cross-sectional survey of sexual and gender minority (SGM) prostate cancer survivors in North America, to explore the association between race/ethnicity and HRQOL. General mental and physical HRQOL was assessed using the Short-Form Health Survey version 2 (SF-12). The frequency and distress of prostate cancer specific symptoms was assessed using the Expanded Prostate Cancer Composite (EPIC) scale. Multivariable linear regression was used to estimate mean differences in HRQOL between sexual minority men of color and their white, non-Hispanic counterparts after adjustment for pertinent demographic and medical characteristics. Results: Among 190 participants, 23 (12%) self-identified as non-white and/or Hispanic. In unadjusted analysis, sexual minority men of color compared to their white counterparts reported worse HRQOL scores in the EPIC hormonal summary (73.8 vs. 81.8) and hormonal function (70.9 vs 80.5) domains. Clinically important differences between men of color and their white counterparts were seen in the EPIC bowel function (mean difference (MD): -4.5, 95% CI: -9.9, 0.8), hormonal summary (MD: -8.0, 95% CI: -15.6, -0.4), hormonal function (MD: -9.6, 95% CI: -17.6, -1.6), and hormonal bother (MD: -6.7, 95% CI: -14.4, 1.1) domains. After adjustment for covariates, clinically important differences persisted between men of color and white, non-Hispanic men on the hormonal summary (74.4 vs. 81.7), hormonal function (71.3 vs. 80.3), and hormonal bother (77.0 vs. 82.7) domains. Conclusions: This exploratory study provides the first evidence that sexual minority men of color may have worse HRQOL outcomes compared to white, non-Hispanic sexual minority men following prostate cancer treatment.
