Abstract Introduction During the past 20 years, researchers have studied various aspects of the impact of prostate cancer therapies on patients, partners and couples. Patients and partners reported distress and negative consequences for their relationships resulting from treatment-related sexual side-effects of prostate cancer therapies. Research on rehabilitation strategies in prostate cancer survivorship has focused largely on biomedical interventions although psychosexual intervention research is also gaining ground. This research has never been summarized in such a way that clinicians can use the findings to provide evidence-based support for prostate cancer patients and their partners in survivorship. Objective An international panel of experts has developed a guideline that informs clinicians, patients and partners about the impact of prostate cancer therapies on the sexuality of patients and partners, and on their sexual relationships. It provides guidance for biopsychosocial rehabilitation strategies that help patients and partners recover sexual intimacy after prostate cancer therapy. Methods The guideline panel included international, multidisciplinary clinical experts and researchers in prostate cancer, a reference librarian and a guideline methodologist. A systematic review of the literature, using the Ovid MEDLINE, Scopus, CINAHL, PsychINFO, LGBT Life, and Embase databases was conducted (1995-2022). The review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. Study selection is reported, based on PRISMA guidelines. Evidence for each statement was assigned a strength (A-C) and a level of recommendation (strong, moderate, conditional) which was based on benefit/risk balance. Data synthesis included meta-analyses of high-quality studies (determined by the Cochrane Risk of Bias tool). Results The guideline is contextualized within cultural, ethnic and racial diversity. The needs of individuals with diverse sexual orientations and gender identities are also recognized. Forty-seven statements were generated, guided by a theoretical model of sexual recovery after prostate cancer therapies and by principles that promote clinician-initiated discussion of realistic expectations of sexual outcomes and mitigation of sexual side-effects through biopsychosocial rehabilitation. The statements focus on counseling about the impact of prostate cancer therapies on patients’ and partners’ sexuality and couples’ relationships as well as on biomedical and psychosocial treatment strategies for sexual dysfunction. The guideline statements address the assessment of sexual function and distress, and barriers to providing sexual health care in prostate cancer survivorship in globally varied health care systems. Conclusions The guideline documents the distressing sexual sequelae of prostate cancer therapies and makes evidence-based recommendations for sexual rehabilitation in prostate cancer survivorship. Areas for future research are also outlined. The guideline was supported and funded by the Movember Foundation.

Background: Patients with prostate cancer suffer significant sexual dysfunction after treatment which negatively affects them and their partners psychologically, and strain their relationships. Aim: We convened an international panel with the aim of developing guidelines that will inform clinicians, patients and partners about the impact of prostate cancer therapies (PCT) on patients' and partners' sexual health, their relationships, and about biopsychosocial rehabilitation in prostate cancer (PC) survivorship. Methods: The guidelines panel included international expert researchers and clinicians, and a guideline methodologist. A systematic review of the literature, using the Ovid MEDLINE, Scopus, CINAHL, PsychINFO, LGBT Life, and Embase databases was conducted (1995-2022) according to the Cochrane Handbook for Systematic Reviews of Interventions. Study selection was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Each statement was assigned an evidence strength (A-C) and a recommendation level (strong, moderate, conditional) based on benefit/risk assessment, according to the nomenclature of the American Urological Association (AUA). Data synthesis included meta-analyses of studies deemed of sufficient quality (3), using A Measurement Tool to Assess Systematic Reviews (AMSTAR). Outcomes: Guidelines for sexual health care for patients with prostate cancer were developed, based on available evidence and the expertise of the international panel. Results: The guidelines account for patients' cultural, ethnic, and racial diversity. They attend to the unique needs of individuals with diverse sexual orientations and gender identities. The guidelines are based on literature review, a theoretical model of sexual recovery after PCT, and 6 principles that promote clinician-initiated discussion of realistic expectations of sexual outcomes and mitigation of sexual side-effects through biopsychosocial rehabilitation. Forty-seven statements address the psychosexual, relationship, and functional domains in addition to statements on lifestyle modification, assessment, provider education, and systemic challenges to providing sexual health care in PC survivorship. Clinical Implications: The guidelines provide clinicians with a comprehensive approach to sexual health care for patients with prostate cancer. Strengths & Limitations: The strength of the study is the comprehensive evaluation of existing evidence on sexual dysfunction and rehabilitation in prostate cancer that can, along with available expert knowledge, best undergird clinical practice. Limitation is the variation in the evidence supporting interventions and the lack of research on issues facing patients with prostate cancer in low and middle-income countries. Conclusion: The guidelines document the distressing sexual sequelae of PCT, provide evidence-based recommendations for sexual rehabilitation and outline areas for future research.

BACKGROUND Despite significant sexual dysfunction and distress after localized prostate cancer treatment, patients typically receive only physiologic erectile dysfunction management. The authors performed a randomized controlled trial of an online intervention supporting couples' posttreatment recovery of sexual intimacy. METHODS Patients treated with surgery, radiation, or combined radiation and androgen deprivation therapy who had partners were recruited and randomized to an online intervention or a control group. The intervention, tailored to treatment type and sexual orientation, comprised 6 modules addressing expectations for sexual and emotional sequelae of treatment, rehabilitation, and guidance toward sexual intimacy recovery. Couples, recruited from 6 sites nationally, completed validated measures at the baseline and 3 and 6 months after treatment. Primary outcome group differences were assessed with t tests for individual outcomes. RESULTS Among 142 randomized couples, 105 patients (mostly surgery) and 87 partners completed the 6-month survey; this reflected challenges with recruitment and attrition. There were no differences between the intervention and control arms in Patient-Reported Outcomes Measurement Information System Global Satisfaction With Sex Life scores 6 months after treatment (the primary outcome). Three months after treatment, intervention patients and partners reported more engagement in penetrative and nonpenetrative sexual activities than controls. More than 73% of the intervention participants reported high or moderate satisfaction with module content; more than 85% would recommend the intervention to other couples. CONCLUSIONS Online psychosexual support for couples can help couples to connect and experience sexual pleasure early after treatment despite patients' sexual dysfunction. Participants' high endorsement of the intervention reflects the importance of sexual health support to couples after prostate cancer treatment. LAY SUMMARY This study tested a web-based program supporting couples' sexual recovery of sexual intimacy after prostate cancer treatment. One hundred forty-two couples were recruited and randomly assigned to the program (n = 60) or to a control group (n = 82). The program did not result in improvements in participants' satisfaction with their sex life 6 months after treatment, but couples in the intervention group engaged in sexual activity sooner after treatment than couples in the control group. Couples evaluated the program positively and would recommend it to others facing prostate cancer treatment.

Against the difficult and trying backdrop of the pandemic, cancer investigators persisted, and for patients with lung cancer, that persistence paid off in spectacular ways. With several new FDA approved treatments, as well as 2 new targetable mutations in non-small cell lung cancer (NSCLC), 2020 was a banner year in the overall lung cancer space. ONCOLOGY® recently sat down with Jennifer W. Carlisle, MD, of Emory University's Winship Cancer Institute, to discuss the many advances made during the last year for patients with lung cancer along with her hopes for further significant milestones in the year to come.
