Young Adult Latino Testicular Cancer Survivors: a Pilot Study of Goal-Focused Emotion Regulation Therapy (GET)

Testicular cancer diagnosis and treatment, especially given its threat to sexuality and reproductive health, can be distressing in the formative period of young adulthood. Cohort studies reveal the prevalence of depressive symptoms in testicular cancer exceeds the general population, and young Hispanic/Latino men are at particular risk for adverse outcomes after treatment. In fact, the majority of young adult cancer survivors will experience impairing, distressing, and modifiable physical, behavioral, and psychosocial adverse outcomes that persist long after the completion of primary medical treatment. These include psychological distress, impairment in the navigation and pursuit of life goals, persistent side effects, elevated risk of secondary malignancies and chronic illness, and biobehavioral burden (e.g., enhanced inflammation, dysregulated stress hormones) which influence morbidity and disease-related vulnerabilities. However, few targeted, tailored, culturally-relevant interventions exist to assist young Hispanic/Latino survivors in re-negotiating life goals and regulating cancer-related emotions and none focus on reducing the burden of morbidity via biobehavioral mechanisms.

Young or "emerging" adulthood is a period marked by goal attainment. Chronic illness experienced as "off time" in the lifespan interrupts goal pursuits and threatens valued life directions. As young adults return to goal pursuits, re-entry to post-cancer life can be a critical point in the survivorship trajectory. Behavioral intervention at this time is well positioned to confer longer-term impact. Emergent from our group's preliminary research, we developed and pilot-tested Goal-focused Emotion-Regulation Therapy (GET) as a novel behavioral intervention to enhance self-regulation through improved goal navigation skills, improved sense of purpose, and better ability to regulate emotional responses in young adults with testicular cancer. GET is a promising candidate intervention to address the mechanisms likely complicating the resolution of cancer-related burden.

Responsive to the need for feasible, effective, and scalable interventions that meet the needs of ethnic minority men, 35 Hispanic/Latino young adults (ages 18-39) with testicular cancer will receive 6 sessions of GET. We will evaluate primary and secondary outcomes at baseline, post-treatment, and 3-month follow-up. In addition, identified biomarkers will be assessed at baseline and post-intervention. We predict that GET will be associated with superior distress outcomes, and these advantages will be maintained at 3-months following intervention. We also expect to observe pre-post reductions in adverse biobehavioral indicators (dysregulated diurnal stress hormones, elevated systemic inflammation)

The intervention will be delivered via an interactive video platform to enhance access. However, we believe that GET could be optimized to meet the needs of this group. To this end, we will examine the influence of Latino cultural processes (Machismo, Simpatia, Acculturative Stress), and conduct in-depth qualitative interviews. Findings will be used to adapt the GET intervention for a future randomized efficacy trial. An additional exploratory aim focuses on potential epigenetic vulnerabilities, to understand how environmental influences (via DNA methylation) on genes implicated in stress reactivity and mood regulation are related to cancer adjustment and intervention response.
