Sexual dysfunction and fertility-related distress in young adults with cancer over 5 years following diagnosis: study protocol of the Fex-Can Cohort study.

BACKGROUND: There is a lack of firm knowledge regarding sexual problems and fertility-related distress in young adults following a diagnosis with cancer. Establishing such understanding is essential to identify patients in need of specific support and to develop cancer care accordingly. This study protocol describes the Fex-Can Cohort study, a population-based prospective cohort study investigating sexual dysfunction and fertility-related distress in young adults diagnosed with cancer in Sweden. The primary objective of the study is to determine the prevalence and predictors of sexual dysfunction and fertility-related distress following a cancer diagnosis in young adulthood compared to prevalence rates for the general population. Further aims are to investigate the trajectories of these issues over time, the co-existence between sexual dysfunction and fertility-related distress, and the relation between these issues and body image, anxiety and depression, health-related quality of life, self-efficacy related to sexuality and fertility, and fertility-related knowledge. METHODS: Participants in the Fex-Can Cohort will be identified via the Swedish National Quality Registries for Brain Tumors, Breast Cancer, Gynecological Oncology, Lymphoma, and Testicular Cancer. All patients diagnosed at the ages of 18-39, during a period of 18 months, will be invited to participate. Established instruments will be used to measure sexual function (PROMIS SexFS), fertility-related distress (RCAC), body image (BIS), anxiety and depression (HADS), and health-related quality of life (QLQ-C30); Self-efficacy and fertility-related knowledge will be assessed by study-specific measures. The survey will be administered to participants at baseline (approximately 1.5 year after diagnosis) and at 3 and 5 years post-diagnosis. Registry data will be used to collect clinical variables. A comparison group of 2000 young adults will be drawn from the Swedish population register (SPAR) and subsequently approached with the same measures as the cancer group. DISCUSSION: The study will determine the prevalence and predictors of sexual dysfunction and fertility-related distress in young men and women with cancer. The findings will form a basis for developing interventions to alleviate sexual problems and fertility-related distress in young adults with cancer in the short and long term. TRIAL REGISTRATION: This is an observational cohort study and clinical trial registration was therefore not obtained.

A web-based psycho-educational intervention (Fex-Can) targeting sexual dysfunction and fertility-related distress in young adults with cancer: study protocol of a randomized controlled trial.

BACKGROUND: This study protocol describes the clinical trial of the Fex-Can intervention, a web-based self-help program targeting sexual dysfunction and fertility-related distress. The psycho-educational intervention has been developed in collaboration with young patients with cancer and shown to be feasible. The primary objective is to determine whether the Fex-Can intervention, provided in addition to standard care, is superior to standard care in terms of reduction of sexual dysfunction and fertility-related distress directly after end of the 12-week program. The trial also aims to determine whether the intervention has an effect on the secondary outcomes including health-related quality of life, anxiety, depression, body image, fertility knowledge, and self-efficacy related to sexuality and fertility. METHODS: The trial has an randomized clinical trial (RCT) design with two parallel arms. The active groups receive either the version of the Fex-Can intervention targeting sexual problems or the version targeting fertility-related distress. Control groups receive standard care. Primary outcomes will be sexual function assessed with the Patient-Reported Outcomes Measurement Information System® Sexual Function and Satisfaction measure version 2.0 (SexFS) and fertility-related distress assessed with the Reproductive Concerns After Cancer scale (RCAC). The effect of the intervention will be evaluated directly after end of the program. Primary and secondary outcomes will also be assessed at the short- (12 weeks after end of program) and long-term (20 and 44 months after end of program) follow-up. At least 64 completers will be needed in each arm (total n = 256) to achieve adequate statistical power in the analyses. In order to increase the understanding of how the intervention brings about a possible change, semi-structured interviews will additionally be conducted with a purposeful sample shortly after completion of the intervention. DISCUSSION: If the Fex-Can intervention proves to be efficacious the necessary steps will be taken to implement it in routine care for young adults diagnosed with cancer. Healthcare could thereby be provided with an easily accessible, cost-effective intervention to offer to young adults suffering from fertility-related distress or sexual problems.

Sexual Dysfunction and Reproductive Concerns in Young Men Diagnosed With Testicular Cancer: An Observational Study.

INTRODUCTION: The survival rates for testicular cancer are excellent; still, there is a lack of knowledge regarding important survivorship issues, such as sexual dysfunction and reproductive concerns. AIM: The aim of this study was to investigate the prevalence and predictors of sexual dysfunction and reproductive concerns and the potential association between these issues in young men ∼2 years after a diagnosis of testicular cancer. METHODS: Data were collected from 111 men (response rate = 50%) diagnosed with testicular cancer at age 16-39. Patients were identified via the Swedish National Quality Registry for Testicular Cancer and approached with a survey, including standardized measures of sexual function, reproductive concerns, body image, and health-related quality of life. The survey was sent to participants approximately 2 years after their cancer diagnosis. Clinical variables were collected from the registry. Predictors were identified by multivariable linear regression analyses. MAIN OUTCOME MEASURES: The main outcomes were sexual function, assessed with the Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction measure version 2.0, and reproductive concerns, assessed with the Reproductive Concerns After Cancer scale. RESULTS: Sexual dysfunction was reported by 26% of men, and a high level of reproductive concerns was reported by 28%. Lower satisfaction with sex life was associated with older age (ß = -0.41), negative body image (ß = -0.42), not having a partner (ß = 4.8), and dissatisfaction with sex life before cancer (ß = 8.31). Negative body image was associated with reproductive concerns in the dimensions of fertility potential (ß = 0.06), partner disclosure (ß = 0.08), and child's health (ß = 0.07), whereas having had fertility preservation predicted higher levels of concerns with regard to personal health (ß = 0.52) and achieving pregnancy (ß = 0.53). Clinical variables did not predict either sexual function or reproductive concerns. CLINICAL IMPLICATIONS: Our results show that the majority of young men diagnosed with testicular cancer do not report sexual dysfunction or reproductive concerns 2 years after diagnosis. A sizeable minority, however, does report dysfunction or reproductive concerns, which should be recognized in the follow-up care of this population. STRENGTHS & LIMITATIONS: A strength of the study is the use of high-quality registry data and validated instruments. The lack of Swedish norms for sexual function and reproductive concerns is a possible limitation. CONCLUSION: A subgroup of young men treated for testicular cancer report sexual dysfunction or reproductive concerns approximately 2 years after diagnosis. Factors associated with these issues seem to mainly be psychological, rather than medical, nature. Ljungman L, Eriksson LE, Flynn KE, et al.
