Sexuality is an important aspect of quality of life for adolescent and young adults that remains understudied in cancer patients. Most current knowledge about how cancer and cancer treatments can affect patients’ sexuality pertains to reproductive cancer patients (breast, gynecological, male reproductive organs), whereas only little is known about how the disease affects the sex lives of patients with other types of cancer. This study examined sexual satisfaction and sexual supportive care needs among adolescent and young adult cancer patients, with a particular focus on how the type of cancer a person has is associated with these issues differently. Five hundred seventy-seven (n = 424 females, 73.5%) patients between 18 and 39 years of age at diagnosis and representing all major tumor entities completed the standardized questionnaire. The analysis addressed the following topics: sexual satisfaction (Life Satisfaction Questionnaire), sexual supportive care needs (Supportive Care Needs Survey), and changes in sexuality (Questions on Life Satisfaction Modules). These topics were tested by mean differences between reproductive and non-reproductive cancer, equivalence testing and regression analyses. About one third of the patients reported being dissatisfied with their sexuality and having supportive care needs in this area. Changes in sexuality were significantly more common in women with reproductive cancers than in those who had other types of cancer (t = − 2.693, p = .007), while both groups had equivalence in scores for sexual satisfaction and sexual supportive care needs. Reproductive cancers are not more associated with deterioration of sexual satisfaction (R2 = .002, p = .243), changes in sexuality (R2 = .006, p = .070) or increased sexual supportive care needs than non-reproductive cancers (R2 = .004, p = .131). The results indicate that about a third of adolescents and young adults with both reproductive but also with non-reproductive cancer experience sexual dissatisfaction in similar measure. An equal percentage of these patients also express a desire to receive supportive care in this area. Consequently, health care professionals should address issues of sexuality and cancer as a matter of routine when caring for young adults even when patients have a non-reproductive cancer.

This study compared the perceived social support of young and older adult cancer patients, examining possible influencing factors as well as associations with health-related quality of life. A total of 179 young patients (18–39 years) and 200 older adult patients (> 70 years) with haematological malignancies completed questionnaires on their perceived social support (ISSS-8, scales: Positive Support and Detrimental Interactions, range 0–16) and health-related quality of life (EORTC QLQ-C30). Tests for mean differences, correlations and regression analyses to determine associated variables of social support were performed. No difference was reported between young (M = 13.40, SD = 2.81) and older adult patients (M = 13.04, SD = 3.82; p = .313) for Positive Support. However, young patients (M = 4.16, SD = 3.10) reported having had more Detrimental Interactions than older patients did (M = 1.63, SD = 2.42; p < .001, Cohen’s d = .910). Comparison of the EORTC QLQ-C30 Function scales showed poorer outcomes for young patients on Emotional, Cognitive and Social Functions and a higher outcome on Physical Function compared with older adult patients. Regression analyses indicated that age (young vs. older adult patients) significantly explained proportions of variance in all models, with young age having a negative impact on Emotional, Cognitive and Social Functions and a positive impact on Physical and Role Functions compared with old age. Significant associations between Detrimental Interactions and all the scales examined except Cognitive Function were found. The difference in negative perceptions of social support in young vs. older adult patients and its impact on health-related quality of life emphasises the necessity of differentiating between positive and negative social support. Negative interactions should be addressed through psychosocial care, particularly with young cancer patients.

In recent years, there has been an increased research focus on adolescent and young adult (AYA) cancer patients. Few longitudinal studies have taken into consideration the specifics of their life situation and the status of psychosocial care services for this population. Our ongoing study aims to determine the psychosocial life and supportive care situation of AYA cancer patients, to describe risk groups, and to develop recommendations for their psycho-oncological care and support. The AYA-Leipzig study (AYA-LE) is a German prospective, longitudinal, study examining AYAs´ life situation (e.g. psychological distress, quality of life) and psychosocial care (e.g. evaluation and preferences, support needs) using two measurement points, namely, upon acute treatment completion (baseline) and 12 months later. N = 577 AYA cancer patients aged between 18 and 39 years at diagnosis, and representing all major tumor entities fill out a standardized questionnaire (online or by post), mainly based on validated instruments. AYA-specific concerns (e.g. family planning, sexual and reproductive health, social support, health behavior) will explicitly be considered. Participants are recruited in 16 German acute care hospitals, four rehabilitation clinics, and from two German state tumor registries. In summary, our longitudinal study will create a large database encompassing all malignant tumor entities and including detailed information about the distress and quality of life, specific problems, and specific support needs of AYA cancer patients at two different points in time post-diagnosis. The information we gather about existing psychosocial care and patient preferences and desires concerning psycho-oncological care will be used to develop recommendations for psycho-oncological care providers.

Background: Distress is highly prevalent among patients with cancer, but supportive care needs often go unmet. Digital therapeutics hold the potential to overcome barriers in cancer care and improve health outcomes. Objective: This study conducted a randomized controlled trial to investigate the efficacy of Mika, an app-based digital therapeutic designed to reduce distress across the cancer trajectory. Methods: This nationwide waitlist randomized controlled trial in Germany enrolled patients with cancer across all tumor entities diagnosed within the last 5 years. Participants were randomized into the intervention (Mika plus usual care) and control (usual care alone) groups. The participants completed web-based assessments at baseline and at 2, 6, and 12 weeks. The primary outcome was the change in distress from baseline to week 12, as measured by the National Comprehensive Cancer Network Distress Thermometer. Secondary outcomes included depression, anxiety (Hospital Anxiety and Depression Scale), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and quality of life (Clinical Global Impression-Improvement Scale). Intention-to-treat and per-protocol analyses were performed. Analyses of covariance were used to test for outcome changes over time between the groups, controlling for baseline. Results: A total of 218 patients (intervention: n=99 and control: n=119) were included in the intention-to-treat analysis. Compared with the control group, the intervention group reported greater reductions in distress (P=.03; ηp²=0.02), depression (P<.001; ηp²=0.07), anxiety (P=.03; ηp²=0.02), and fatigue (P=.04; ηp²=0.02). Per-protocol analyses revealed more pronounced treatment effects, with the exception of fatigue. No group difference was found for quality of life. Conclusions: Mika effectively diminished distress in patients with cancer. As a digital therapeutic solution, Mika offers accessible, tailored psychosocial and self-management support to address the unmet needs in cancer care.
