Understanding the Effects of Prostate Cancer on Gay and Bisexual Men

描述（由申请人提供）：本申请是对PA-12-113，LGBTI人群健康研究的回应，该研究“鼓励研究人员调查与LGBTI健康相关的新问题”，“高度重视[LGBTI]个人干预研究”。“前列腺癌（PCa）的生存就是这样一个领域。在整个生命周期中，六分之一的同性恋和双性恋男性（GBM）和三分之一的男性伴侣将被诊断患有PCa，使PCa成为影响GBM的最常见癌症。然而，几乎没有研究检查PCa治疗对GBM性功能的影响。性功能障碍是PCa治疗的主要后遗症，其本身令人深感痛苦，并对治疗后的生活质量产生负面影响，导致严重的负面心理健康结果。最近的研究表明，PCa治疗的性结局对GBM来说比异性恋男性明显更差。肛交和阴道性交之间的生理差异可能至少部分解释了这种健康差异。定制治疗需要开发，但几乎完全没有探索。缺少的是评估PCa治疗对GBM性功能影响的研究，康复结果的研究，以及指导开发针对GBM和男性性别的新治疗方法的研究。 本研究的长期目标是开发第一个针对GBM的循证PCa康复课程。作为第一步，在R21中，我们将进行必要的形成性研究，以估计不良结局的程度，确认需求，并评估可接受性和可行性。有三个具体目标。在目标1中，我们将深入研究PCa治疗对GBM性生活、其伴侣及其关系的影响。我们将在全国范围内对多达48名GBM PCa患者、伴侣和夫妇进行半结构化、聊天或电话访谈研究。在目标2中，我们将完善定义并制定评估GBM性功能障碍所需的措施。在目标3中，我们将对220名患有前列腺癌的GBM进行在线定量调查，该调查将a）量化治疗后的性挑战，B）评估康复需求和优先事项，c）开发新的量表来衡量GBM的性功能，d）评估新的康复课程对患有前列腺癌的GBM的可接受性和可行性。

DESCRIPTION (provided by applicant): This application is in response to PA-12-113, Research on the Health of LGBTI Populations, which "encourages researchers to investigate new questions related to LGBTI health" with "high priority placed on research on interventions for [LGBTI] individuals." Survivorship of prostate cancer (PCa) is one such area. Across the lifespan, 1-in-6 gay and bisexual men (GBM) and 1-in-3 male couples will be diagnosed with PCa, making PCa the most common cancer affecting GBM. Yet, almost no research has examined the effects of PCa treatment on GBM's sexual functioning. Sexual dysfunction is the major sequela of PCa treatment, which is deeply distressing in itself, and negatively impacts quality of life post-treatment, resulting in serious negative mental health outcomes. Recent studies indicate sexual outcomes of PCa treatment are significantly worse for GBM than heterosexual men. Physiological differences between anal sex and vaginal sex likely explain, at least in part, this health disparity. Tailored treatment needs to be developed, but is almost entirely unexplored. Missing is research to evaluate the effects of PCa treatment on GBM sexual functioning, research on rehabilitation outcomes, and research to guide development of new treatments tailored to GBM and sex between men. The long-term objective of this research is to develop the first evidence-based PCa rehabilitation curriculum tailored for GBM. As a first step, in this R21 we will conduct the formative research needed to estimate the extent of poor outcomes, confirm need, and assess acceptability and feasibility. There are three specific aims. In Aim 1, we will investigate, in-depth, the experience of PCa treatment on the sexual lives of GBM, their partners, and their relationships. We will conduct a semi-structured, chat or phone interview study of up to 48 GBM PCa patients, partners, and couples, nationally. In Aim 2, we will refine definitions and develop the measures needed to assess sexual dysfunction in GBM. In Aim 3, we will conduct an online quantitative survey of 220 GBM with PCa, which will a) quantify sexual challenges post-treatment, b) assess needs and priorities for rehabilitation, c) develop a new scale to measure sexual functioning in GBM and d) assess the acceptability and feasibility of a new rehabilitation curriculum for GBM with PCa.
