Psychiatric Disorder Incidence Among Adolescents and Young Adults Aged 15-39 With Cancer: Population-Based Cohort

Long-term health outcomes by cancer diagnosed age among adolescent and young adult: multinational representative database

BACKGROUND

The cancer experienced in adolescent and young adult (AYA) could disturb developmental changes and long-term life. The current AYA guidelines and research for survivorship were developed and reported according to the general age range of 15-39 years; however, expected life events vary by diagnosed age. We aimed to examine the social, psychological, and physical well-being of AYA cancer survivors by age at diagnosis using a multinational representative dataset focusing on age at diagnosis.

METHODS

We conducted a cross-sectional study using the US and Korean National Health and Nutrition Examination Surveys from 2007 to 2018. Participants diagnosed with any cancer aged 15-39 years and were aged > 18 years at the survey year were defined as AYA cancer survivors. AYA were classified into three groups based on their diagnosed age: adolescent survivors (diagnosed between the ages of 15 and 19, n = 45), young adult survivors (diagnosed between the ages of 20 and 29, n = 238), and late young adult survivors (diagnosed between the ages of 30 and 39, n = 539). We also selected an age-, sex-, race-, and survey year-matched general population with 1:5 ratio among participants without cancer (N = 4110).

RESULTS

The average age of the survey was 29.1, 43.7, and 48.7 years for AYA survivors diagnosed during adolescence, young adulthood, and late young adulthood, respectively. Adolescent survivors had more non-couple marital status (adjusted odds ratio (aOR), 1.34; 95% CI, 1.10-1.64) and unemployed (aOR, 1.30; 95% CI, 1.05-1.61) compared to late young adult survivors. Comparing with the matched general, adolescent survivors were more in poor general health (aOR, 4.65; 95% CI, 2.09-10.38) and unemployed (aOR, 2.17; 95% CI, 1.12-4.24) and late young adult survivors were more non-couple (aOR, 1.40; 95% CI, 1.05-1.86).

CONCLUSION

This study provides evidence for future studies on long-term health, which may vary according to age at the time of diagnosis among AYA with cancer.

Mental Health Service Contact Following Cancer Diagnosis and Associations with Cancer Mortality: Results from a Linked Population-Based Study of Adolescents and Young Adults in New South Wales

Purpose: To assess the mental health conditions, as indicated by mental health service contact in adolescents and young adults (AYAs) diagnosed with cancer in New South Wales (NSW) and associations with cancer mortality. Methods: In 3998 NSW AYAs diagnosed with cancer in 2005-2017, mental health service contacts were obtained from hospital inpatient records and specified medical and pharmaceutical insurance claims. Odds of postcancer mental health contact were assessed by precancer mental contacts using logistic regression adjusted for sociodemographic and cancer characteristics. The risk of cancer-specific mortality related to postcancer mental health contacts was estimated using competing risk regression. Results: The prevalence of mental health service contacts in the 5 years postcancer diagnosis was 27.0%, higher than the corresponding precancer prevalence of 21.4%. The most common mental health conditions were depression and anxiety. The odds of having a mental health contact postcancer diagnosis were higher in patients with a precancer mental health service contact (adjusted odds ratio 5.69, confidence intervals [95% CIs]: 4.90-6.75). The 5-year cancer-specific survival was 87.9% (95% CI: 85.8-89.8) for patients with a mental health service contact postcancer, which was lower than the 93.9% (95% CI: 93.0-94.7) for patients without this contact. The subhazard ratio (SHR) for cancer mortality in patients having mental health service contact postcancer diagnosis was 1.67 (95% CI: 1.29-2.15), adjusted for sociodemographic characteristics, cancer stage, and precancer mental health status. Conclusion: The prevalence of mental health service contact increased after a cancer diagnosis. Mental health care should be a continued priority for AYA cancer patients, particularly for high-risk groups.

Mental Disorders Among Adolescents and Young Adults With Cancer: A Canadian Population-Based and Sibling Cohort Study

PURPOSE

To compare the cumulative incidence of mental disorders among adolescents and young adults (AYAs) diagnosed with cancer with the general population and their unaffected siblings.

METHODS

A retrospective, population-based, matched cohort design was used to investigate the impact of cancer diagnosis on mental disorders among individuals age 15-39 diagnosed between 1989 and 2019. Two cancer-free cohorts were identified: matched population-based and sibling cohorts. Outcomes included incidence of mood and anxiety disorders, substance use disorders, suicide outcomes, psychotic disorders, and any of the preceding four categories within 5 years of cancer diagnosis. Competing risk regression was used to estimate adjusted subhazard ratios (aSHR) and 95% CIs.

RESULTS

Among 3,818 AYAs with cancer matched to the population-based cancer-free cohort, individuals with cancer were more likely to be diagnosed with incident mental disorders than those without cancer; the risk was highest immediately after a cancer diagnosis and decreased over time with aSHR [95% CI] for mood and anxiety disorders at 0-6 months (11.27 [95% CI, 6.69 to 18.97]), 6-12 months (2.35 [95% CI, 1.54 to 3.58]), and 12-24 months (2.06 [95% CI, 1.55 to 2.75]); for substance use disorders at 0-6 months (2.73 [95% CI, 1.90 to 3.92]); for psychotic disorders at 0-6 months (4.69 [95% CI, 2.07 to 10.65]); and for any mental disorder at 0-6 months (4.46 [95% CI, 3.41 to 5.85]), 6-12 months (1.56 [95% CI, 1.14 to 2.14]), and 12-24 months (1.7 [95% CI, 1.36 to 2.13]) postcancer diagnosis. In sibling comparison, cancer diagnosis was associated with a higher incidence of mood and anxiety and any mental disorder during first 6 months of cancer diagnosis.

CONCLUSION

AYAs with cancer experience a greater incidence of mental disorders after cancer diagnosis relative to population-based and sibling cohorts without cancer, primarily within first 2 years, underscoring the need to address mental health concerns during this period.

Nutritional status, body composition and diet quality in children with cancer

During cancer treatment, nutritional status disorders such as malnutrition or obesity affect the tolerance of cancer treatment, quality of life, but also the pharmacokinetics of drugs. It is hypothesized that changes in fat and lean body mass can modify chemotherapy volume distribution, metabolism and clearance. In children with cancer, lean body mass decreases or remains low during treatment and fat mass increases. Body composition is influenced by the cancer itself, aggressive multimodal-therapies, changes in metabolism, unbalanced diet and reduced physical activity. Due to the side effects of treatment, including changes in the sense of taste and smell, nausea, vomiting, diarrhea, and stress, eating according to recommendation for macronutrients and micronutrients is difficult. Research indicates that throughout cancer treatment, the consumption of fruits, vegetables, and dairy products tends to be insufficient, whereas there is an elevated intake of sugar and unhealthy snacks. Children exhibit a preference for high-carbohydrate, salty, and strongly flavored products. This review revealed the importance of body composition and its changes during cancer treatment in children, as well as eating habits and diet quality.

Psychological Outcomes in Adolescent and Young Adult Cancer Survivors

The diagnosis of cancer during adolescent and young adulthood (AYA) may alter the development and psychological trajectory of survivors across their lifespan. The current review focuses broadly on emotional health, social functioning, health behaviors, and cancer-related cognitive impairment (CRCI) among AYA survivors. Overall, AYA survivors appear to be at elevated risk of emotional distress symptoms, mood and anxiety disorders, suicide, and mental health care service utilization compared with individuals without a cancer history. Difficulties with social relationships and reduced achievement of expected social outcomes including educational attainment and employment have been reported. Despite risk for health-related morbidities, including subsequent neoplasms, many AYA survivors do not engage in health behaviors at the recommended levels for physical activity, diet, or tobacco and alcohol use. Although CRCI has not been comprehensively characterized in this population, subgroups of AYA survivors appear to be at risk for experiencing CRCI, including survivors of central nervous system tumors, Hodgkin lymphoma, testicular, and breast cancer. Across each considered domain of psychological functioning, intervention efforts have largely focused on acceptability and feasibility with an increasing focus on e/mHealth approaches. Future research should include multiphase studies, including randomized controlled trials designed to evaluate intervention efficacy and effectiveness. It is imperative that psychological interventions consider the unique needs of AYA survivors by developmental stage and across multiple levels of influence (patient, support system, institution, and health care system).

Illness Perceptions, Fear of Cancer Recurrence, and Mental Health in Teenage and Young Adult Cancer Survivors

Background: The Common-Sense Model of illness self-regulation underpins illness-specific cognitions (including both illness perceptions and a fear of cancer recurrence; FCR). There is evidence in adults of associations between FCR, illness perceptions, and mental health in adult cancer survivors. However, there is limited empirical research examining these constructs within the developmentally distinct population of adolescent and young adult (AYA) survivors of cancer. The current study aimed to bridge that gap to inform potentially modifiable treatment targets in this population. Method: A cross-sectional, correlational design was used to examine the associations between illness perceptions, FCR, and mental health. A web-based survey was completed by a convenience sample of AYA survivors. Regression and mediation analyses were performed. Results: Overall, more negative illness perceptions were associated with more severe FCR and greater depressive and anxiety symptomatology. Higher FCR was predictive of worse overall mental health. More negative overall illness perceptions predicted the relationship between FCR-depression, mediating 24.1% of the variance. Contrastingly, overall illness perceptions did not predict or mediate the relationship between FCR-anxiety. However, the specific illness perceptions regarding timeline, personal control, and emotional representation, were predictive of the FCR-anxiety relationship. Discussion: Illness perceptions and FCR were predictive of mental health outcomes. Identifying and therapeutically targeting negative illness perceptions in those young adults who have survived adolescent cancer could therefore be a means of reducing anxiety and depressive symptomatology. Limitations and future directions are discussed.

Neuropsychiatric complications and associated management in adolescent and young adult cancer survivors: An All of Us study

BACKGROUND

About 4.5% of new cancer cases affect adolescent and young adult aged between 15 and 39 years in the United States (US). However, the effect of neuropsychiatric conditions on long-term adolescent and young adult cancer (AYAC) survivors has not been formally investigated. Thus, the impact and management of late neuropsychiatric complications in AYAC survivors compared to non-cancer-matched controls (NCMC) in the US were evaluated using the All of Us (AoU) Research Program.

METHODS

Participants in the AoU Controlled Tier Dataset (v6) diagnosed with cancer between ages 15 and 39 were identified from electronic health records and surveys. AYAC survivors were matched with NCMC using the optimal pair-matching algorithm at a 1:4 ratio. Data on past diagnoses, current follow-up care, and treatment patterns of neuropsychiatric complications were collected.

RESULTS

Analysis was performed on 788 AYAC survivors and 3152 NCMC. AYAC survivors, with an average of 8.8 years since their first cancer diagnosis, were more likely than NCMC to receive a diagnosis of neuropathy, memory loss and epilepsy (p  < 0.001). Survivors also had a higher rate of follow-up care and treatment utilization for these neurological conditions compared to NCMC (p  < 0.05). Treatment utilization was highest among survivors receiving care for epilepsy (88%), and lower for neuropathy (70%), memory loss (61%), and chronic fatigue (59%).

CONCLUSIONS

This large study reveals that AYAC survivors, on average 9 years after their cancer diagnosis, require more frequent follow-up care for neurological complications compared to non-cancer individuals. However, the management of neuropathy, memory loss, and chronic fatigue is hindered by a lack of mechanism-based effective therapies.

Mental health and care utilization in survivors of adolescent and young adult cancer

BACKGROUND

Adolescent and young adult cancer survivors experience mental health challenges, yet little is known about the evolution of these difficulties. This study explored mental health symptoms and utilization among long-term adolescent and young adult cancer survivors.

METHODS

Using 30 432 respondents from the 2019 National Health Interview Survey, this study compared adults with a history of adolescent and young adult cancer (diagnosed when patients were between 15 and 39 years of age) to adults without adolescent and young adult cancer. Mental health symptom severity was measured using the Patient Health Questionnaire depression scale and 7-item Generalized Anxiety Disorder questionnaires. Care utilization constituted psychotherapy and mental health medication use. Inverse propensity score weights were used to balance demographics and combined with survey weights. Descriptive statistics, multivariable generalized linear models, and structural equation modeling with 2-sided tests were used for analysis.

RESULTS

We compared 639 adolescent and young adult survivors with 29 793 controls. Survivors were, on average, 20.5 years (SE = 0.74) past their cancer diagnosis dates. After adjusting for survey and propensity score weights, adolescent and young adult survivors reported more severe depression (incidence rate ratio = 1.42, 95% confidence interval [CI] = 1.09 to 1.84, P < .01) and anxiety (incidence rate ratio = 1.85, 95% CI = 1.55 to 2.21, P < .001). They were more likely to use psychotherapy (odds ratio = 1.91, 95% CI = 1.16 to 3.17, P < .05) and mental health medications (odds ratio = 1.89, 95% CI = 1.15 to 3.11, P < .05). Time since diagnosis was negatively associated with symptoms and utilization. Structural equation modeling demonstrated mediation of utilization effect by symptom severity.

CONCLUSIONS

Adolescent and young adult survivors experience worse mental health in late survivorship, despite small improvements over time. We highlight the importance of survivorship care that addresses the long-term mental health needs of these survivors.
