Sexual Health Among Young Adults Treated with Chimeric Antigen Receptor T Cell Therapy: A Mixed-Methods Study

<b><i>Purpose:</i></b> Chimeric antigen receptor T cell therapy (CAR-T) is a breakthrough treatment for hematological malignancies, but sexual health, crucial for quality of life among young adults (YAs) ages 18-39, remains unexplored among YA CAR-T recipients. This study explored sexual health and patient-provider sexual health communication among YAs post-CAR-T. <b><i>Methods:</i></b> This cross-sectional mixed-methods study recruited YAs ≤5 years post-CAR-T. Participants completed Patient-Reported Outcomes Measurement Information System measures assessing sexual health and study-specific items assessing patient-provider sexual health communication. A subset completed a semistructured interview exploring the impact of CAR-T on sexual health and patient-provider sexual health communication. Descriptive statistics compared quantitative data to evidence-based thresholds. Qualitative data were thematically analyzed. <b><i>Results:</i></b> Fourteen YAs participated; 11 completed interviews. Median age was 33 years (range: 22-39), 64.3% were male, 92.9% were heterosexual, and median time post-CAR-T was 22 months. Interest in sexual activity was low among females (mean [M] = 35.1, standard deviation [SD] = 10.0), and orgasm ability was low among males (M = 39.3, SD = 19.5). Females reported less interest in sexual activity than males. Most YAs had not (50.0%) or did not recall (35.7%) discussing sexual health with a provider pre-CAR-T. Most (78.6%) had not discussed sexual health with a provider post-CAR-T. Three higher level qualitative themes emerged as follows: (1) treatment negatively affected libido, sexual activity, and romantic relationships, (2) YAs face challenges communicating with health care providers about sexual health, and (3) there is limited sexual health education and support for YAs. <b><i>Conclusion:</i></b> Findings highlight a need for improved patient-provider communication about sexual health and educational resources for YA CAR-T recipients.
