Introduction With earlier prostate cancer (PCa) diagnosis and an increased focus on survivorship, post-treatment sexual quality of life (QoL) has become increasingly important. Research and validated instruments for sexual QoL assessment based on heterosexual samples have limited applicability for men-who-have-sex-with-men (MSM). Aim We aimed to create a validated instrument for assessing sexual needs and concerns of MSM post-PCa treatment. Here we explore post-PCa treatment sexual concerns for a sample of MSM, as the first part of this multi-phase project. Methods Individual semi-structured interviews were conducted with 16 MSM face-to-face or via Internet-based video conferencing. Participants were asked open-ended questions about their experiences of sexual QoL following PCa. Interviews were recorded, transcribed verbatim, uploaded to NVivo 8TM, and analyzed using qualitative methodology. Main Outcome Measure We have conducted semi-structure qualitative interviews on 16 MSM who were treated for PCa. Focus was on post-treatment sexual concerns. Results The following themes were inductively derived: (i) erectile, urinary, ejaculation, and orgasmic dysfunctions; (ii) challenges to intimate relationships; and (iii) lack of MSM-specific oncological and psychosocial support for PCa survivorship. Sexual practices pre-treatment ranked in order of frequency were masturbation, oral sex, and anal sex, an ordering that prevailed post-treatment. Sexual QoL decreased with erectile, urinary, and ejaculation dysfunctions. Post-treatment orgasms were compromised. Some single men and men in non-monogamous relationships reported a loss of confidence or difficulty meeting other men post-treatment. Limited access to targeted oncological and psychosocial supports posed difficulties in coping with PCa for MSM. Conclusions The negative impact on sexual QoL can be severe for MSM and requires targeted attention. Penile–vaginal intercourse and erectile function have been the primary focus of sexual research and rehabilitation for men with PCa, and do not adequately reflect the sexual practices of MSM. Our findings suggest that future research dedicated to MSM with PCa is needed to incorporate their sexual practices and preferences specifically into treatment decisions, and that targeted oncological and psychosocial support services are also warranted.
Introduction There is limited data on post-treatment quality of life (QoL) for men-who-have-sex-with-men (MSM) with prostate cancer (PCa). QoL in MSM may not be reflected by assessment tools designed for the heterosexual population. Aims Our goals were to evaluate post-treatment QoL in PCa patients who are MSM, and to investigate the utility of current QoL assessment tool. Methods PCa patients treated with surgery and/or radiation were recruited from the local MSM community. Each participant completed the Expanded Prostate Cancer Index Composite (EPIC) questionnaire, Male Sexual Health Questionnaire (MSHQ), and a questionnaire focused on insertive and receptive roles of anal intercourse. Main Outcome Measures Response scores were calculated based on questionnaire design and compared by treatment modality. Results Seven participants treated with surgery (mean age 58) and eight participants treated with radiation (mean age 67) were recruited. No participant in the surgical group received androgen deprivation therapy (ADT) while two in radiation group were treated with ADT. The sample size of this study did not permit formal statistical analysis, although potential differences in Urinary and Bowel Domains from EPIC and Ejaculation Scale from MSHQ were observed. More participants from the radiation group seemed to be able to maintain both insertive and receptive anal intercourse roles after treatment compared to participants who received surgery. Conclusions While the two validated assessment tools suggested similar QoL scores including sexual function for both surgical and radiation groups, post-treatment sexual function related to anal intercourse may be better in the radiation group, as compared to the surgical group. Larger studies in PCa patients from MSM community are warranted to verify these data.
Aim: The expanded prostate cancer index composite (EPIC) is a widely adopted instrument for the quality of life of patients with prostate cancer. We aimed to create a Chinese version of EPIC to further research in the Chinese-speaking population.Methods: A prototype was created by forward-backward translations and revisions. During cultural adaptation, 15 participants were interviewed after they had completed the prototype. A few issues highlighted included confusion related to the question format, subject non-familiarity with the Chinese term for "hot flashes," and the use of the Chinese term for "breast" as a strictly female body part. A pilot version was created based on the cultural adaptation findings. Validation of the pilot version was performed by having 50 participants complete the Chinese EPIC and EORTC QLQ-c30 twice within a 4-week period. Test-retest reliability (Pearson's correlations and difference distribution) and internal consistency (Cronbach's ) were measured using SAS version 9.4. Results:Test-retest reliability values for the urinary, bowel, sexual and hormone domains were 0.71, 0.51, 0.51 and 0.66, respectively; subscale test-retest reliability ranged between 0.29 and 0.82. Internal consistency for domains was good with Cronbach's ranging from 0.76 to 0.78 for the initial test and 0.67 to 0.85 for the retest. The performance of this version of EPIC was comparable to the validated EORTC QLQ-C30. Conclusion:The EPIC questionnaire was successfully translated into Chinese and was culturally adapted. The resultant Chinese version has high reliability and validity and will be an important tool for research on quality of life in the Chinese population.
Background: Prostate cancer (PCa) is often diagnosed early with prolonged survival, which makes sexual quality of life (QoL) an increasingly important treatment consideration, but existing QoL questionnaires have limited applicability for men who-have-sex-with-men (MSM) beyond penile erections and penetrative sex. Aim: We aimed to create a validated survey instrument for assessing a variety of sexual activities beyond penile insertive sex for MSM after PCa treatment. Methods: Based on our previously published survey findings, we have generated a prototype questionnaire with 13 different domains, reviewed by both healthy MSM and pilot-tested by MSM treated for PCa.Outcomes: We report here on progress in developing the questionnaire and demonstrate the complexity of MSM sexual side effects resulting from PCa treatment(s). Results: Statistical analysis of 204 responses from MSM treated for PCa showed that each domain performed well individually (Cronbach's alpha coefficients ranged from 0.80 to 0.95; item-total correlations ranged from 0.16 to 0.89), with many significant intercorrelations between the domains (ranged from -0.048 to 0.93). Clinical Implications: The questionnaire can contribute to clinical diagnosis and treatment decisions that best fit the preferred sexual practices of individual MSM. Strengths & Limitations:The current questionnaire considers a much broader repertoire of MSM's sexual practices and preferences than other currently available questionnaires. The high intercorrelations between the many parameters demonstrate that problems in one domain can affect other domains. This preliminary analysis warrants further exploration with a larger sample size. Conclusions: Once validated our questionnaire should help develop tailored psychosocial supports for MSM experiencing sexual dysfunction after PCa treatment and help newly diagnosed MSM with PCa make treatment decisions informed by their preferred sexual practices.
