Substance use among adolescent and young adult cancer survivors

Clinical, demographic factors, and substance use among Hispanic and non-Hispanic young adult childhood cancer survivors

PURPOSE

The purpose of this study is to examine the protective and risk factors of substance use behaviors (tobacco, marijuana, e-cigarette, and alcohol) among young adult childhood cancer survivors. The study focused on clinical (receipt of cancer-related follow-up care, treatment intensity, late effects, depressive symptoms, self-rated health) and demographic (race/ethnicity, neighborhood socioeconomic status) factors and their associations with substance use.

METHODS

Participants were from the Project Forward cohort, a population-based study of young adult survivors of childhood cancers. Participants (N = 1166, Mage = 25.1 years) were recruited through the Los Angeles Cancer Surveillance Program (Cancer Registry covering Los Angeles County, California). Multivariate path analyses were performed with substance use as the outcome variables and clinical and demographic factors as independent variables. Covariates included age and sex.

FINDING

Substance use was positively associated with depressive symptoms, and inversely associated with cancer-related follow-up care, female sex, age, Hispanic ethnicity, treatment intensity, and self-rated health. Neighborhood SES was inversely associated with tobacco use, while being positively associated with binge drinking and e-cigarette use. The results highlight the interrelationship between the clinical and demographic variables and their associations with different substance use.

CONCLUSION

Findings support the need for effective interventions targeting substance use behavior among CCS. This will help improve long-term outcomes and mitigate the risk for early morbidity.

The Microbiome-Gut-Brain axis regulates social cognition & craving in young binge drinkers

BACKGROUND

Binge drinking is the consumption of an excessive amount of alcohol in a short period of time. This pattern of consumption is highly prevalent during the crucial developmental period of adolescence. Recently, the severity of alcohol use disorders (AUDs) has been linked with microbiome alterations suggesting a role for the gut microbiome in its development. Furthermore, a strong link has emerged too between microbiome composition and socio-emotional functioning across different disorders including AUD. The aim of this study was to investigate the potential link (and its predictive value) between alcohol-related altered microbial profile, social cognition, impulsivity and craving.

METHODS

Young people (N = 71) aged 18-25 reported their alcohol use and underwent a neuropsychological evaluation. Craving was measured at baseline and three months later. Diet was controlled for. Blood, saliva and hair samples were taken for inflammatory, kynurenine and cortisol analysis. Stool samples were provided for shotgun metagenomic sequencing and short-chain fatty acids (SCFAs) were measured.

FINDINGS

Binge drinking was associated with distinct microbiome alterations and emotional recognition difficulties. Associations were found for several microbiome species with emotional processing and impulsivity. Craving showed a strong link with alterations in microbiome composition and neuroactive potential over time.

INTERPRETATION

In conclusion, this research demonstrates alterations in the gut microbiome of young binge drinkers (BDs) and identifies early biomarkers of craving. Associations between emotional processing and microbiome composition further support the growing literature on the gut microbiome as a regulator of social cognition. These findings are of relevance for new gut-derived interventions directed at improving early alcohol-related alterations during the vulnerability period of adolescence.

Health behaviors in adolescent survivors of cancer: An integrative review

PROBLEM

Adolescent survivors of cancer face an increased risk of chronic health conditions that can be improved by healthy behaviors. The purpose of this review is to synthesize the extent/prevalence of health behaviors (physical activity [PA], diet, human papillomavirus [HPV] vaccination, alcohol use, smoking, marijuana use, and unprotected sex) compared to age-matched peers and factors associated with those behaviors.

ELIGIBILITY CRITERIA

Four databases (PubMed, EMBASE, PsycINFO, and CINAHL) were searched for peer-reviewed primary studies published since 2000 including adolescents aged 11-20 years-old, who had completed cancer treatments. Studies reporting at least one behavior were included.

SAMPLE

Of 1979 articles reviewed, 27 studies reporting any of the following health behaviors were included: PA, diet, HPV vaccination, alcohol use, smoking, marijuana use, or unprotected sex.

RESULTS

Adolescent survivors of cancer engaged less in health risk behaviors (alcohol use, smoking, marijuana use, and unprotected sex) or health-promoting behaviors (PA, healthy diet, and HPV vaccination) compared to age-matched peers. Their health behaviors were associated with psychosocial factors including emotional discomfort (e.g., feeling depressed or nervous) and influence of others (family, friends, and healthcare providers).

CONCLUSIONS

Although health risk behaviors in adolescent survivors of cancer are not as prevalent as in their peers, the survivors' low engagement in health-promoting behaviors including PA, diet, and HPV vaccination is concerning.

IMPLICATIONS

More research is needed to develop and evaluate interventions to improve health-promoting behaviors in adolescent survivors of cancer by strengthening or facilitating psychosocial resources.

Routes of administration, reasons for use, and approved indications of medical cannabis in oncology: a scoping review

INTRODUCTION

Some patients diagnosed with cancer use medical cannabis to self-manage undesirable symptoms, including nausea and pain. To improve patient safety and oncological care quality, the routes of administration for use of medical cannabis, patients' reasons, and prescribed indications must be better understood.

METHODS

Based on the Joanna Briggs Institute guidelines, a scoping review was conducted to map the current evidence regarding the use of medical cannabis in oncological settings based on the experiences of patients diagnosed with cancer and their healthcare providers. A search strategy was developed with a scientific librarian which included five databases (CINAHL, Web of Science, Medline, Embase, and PsycINFO) and two grey literature sources (Google Scholar and ProQuest). The inclusion criteria were: 1) population: adults aged 18 and over diagnosed with cancer; 2) phenomena of interest: reasons for cannabis use and/or the prescribed indications for medical cannabis; 3) context: oncological setting. French- or English-language primary empirical studies, knowledge syntheses, and grey literature published between 2000 and 2021 were included. Data were extracted by two independent reviewers and subjected to a thematic analysis. A narrative description approach was used to synthesize and present the findings.

RESULTS

We identified 5,283 publications, of which 163 met the eligibility criteria. Two main reasons for medical cannabis use emerged from the thematic analysis: limiting the impacts of cancer and its side effects; and staying connected to others. Our results also indicated that medical cannabis is mostly used for three approved indications: to manage refractory nausea and vomiting, to complement pain management, and to improve appetite and food intake. We highlighted 11 routes of administration for medical cannabis, with oils and oral solutions the most frequently reported.

CONCLUSION

Future studies should consider the multiple routes of administration for medical cannabis, such as inhalation and edibles. Our review highlights that learning opportunities would support the development of healthcare providers' knowledge and skills in assessing the needs and preferences of patients diagnosed with cancer who use medical cannabis.

Prevalence of mental disorders in patients with cancer compared to matched controls - secondary analysis of two nationally representative surveys

AIM

To compare prevalence rates of mental disorders in patients with cancer and general population controls.

METHOD

In two stratified nationally representative surveys, the 12-month prevalence of mental disorders was assessed in 2141 patients with cancer and 4883 general population controls by the standardized Composite International Diagnostic Interview (CIDI). We determined odds ratios (ORs) to compare the odds for mental disorders (combined and subtypes) in cancer patients with age- and gender-matched controls.

RESULTS

The 12-month prevalences rate for any mental disorder was significantly higher in patients with cancer compared to controls (OR 1.28, 95% CI 1.14-1.45). Prevalence rates were at least two times higher for unipolar mood disorders (major depression: OR 2.07, 95% CI 1.71-2.51; dysthymia: OR 2.93, 95% CI 2.13-4.02) and mental disorders due to a general medical condition (OR 3.31, 95% CI 2.32-4.71). There was no significant elevation for anxiety disorders overall (OR 0.95, 95% CI 0.81-1.11). Mildly elevated prevalence rates emerged for post-traumatic stress disorder (OR 1.57, 95% CI 1.11-2.23) and social phobia (OR 1.57, 95% CI 1.07-2.31), while specific phobia (OR 0.82, 95% CI 0.67-1.00) and agoraphobia (OR 0.49, 95% CI 0.33-0.73) were significantly less frequent in cancer.

CONCLUSIONS

While elevated depression rates reinforce the need for its systematic diagnosis and treatment, lower prevalences were unexpected given previous evidence. Whether realistic illness-related fears and worries contribute to lower occurrence of anxiety disorders with excessive fears in cancer may be of interest to future research.

Systematic Review of Substance Use Measurement Tools in Adolescent and Young Adult Childhood Cancer Survivors

Substance use among adolescents and young adults (AYAs) is associated with an increased risk of poor physical and mental health outcomes. For AYA childhood cancer survivors (CCSs), substance use may also increase their likelihood of experiencing late effects. As a result, professional organizations recommend that AYA CCSs be regularly screened for risk behaviors, including substance use. The best methods for assessing these behaviors as part of clinical care for AYA CCSs, however, remain unclear. To begin to address this gap, the purpose of this study was to systematically review written substance use measures that have been used with AYA CCSs and published between 2000 and 2020. A search of PubMed, PsycINFO, and CINAHL using terms related to substance use and AYA CCSs identified 47 articles representing 20 different written substance use measures that evaluated current substance use (i.e., use of alcohol, tobacco, marijuana, prescription medications taken in a manner other than as prescribed, and/or other illicit substances within the 12 months). Measures varied in domains assessed, item formats, and response formats. Results are presented alongside recommendations for selecting screening tools for use with AYA CCS populations in both clinical and research settings.

Binge Drinking, Tobacco, and Marijuana Use Among Young Adult Childhood Cancer Survivors: A Longitudinal Study

Objectives: Substance use among young adult childhood cancer survivors (YACCSs) has been found to increase during survivorship, resulting in increased risk of developing long-term negative health outcomes. This investigation sought to determine various risk and protective factors of tobacco, alcohol, or marijuana use over time among a sample of YACCSs. Methods: 127 YACCSs (57% Hispanic, 55% female, average age at diagnosis 12.4 years) who were diagnosed with any cancer type (except Hodgkin lymphoma) at two large pediatric medical centers in Los Angeles County between 2000 and 2007 responded to two surveys separated by ∼5 years. Bivariate logistic regression models were used to assess independent clinical and psychosocial Time 1 variables associated with each substance use outcome at Time 2. Time 1 variables significant at p < .10 were included in multivariable logistic regression models for each Time 2 substance use variable. Results: Rates of 30-day use increased over time for binge drinking alcohol (from 25.6% to 37.7%), marijuana (from 10.6% to 22.1%), and cigarette/tobacco (from 8.9% to 12.2%). Of the following Time 1 variables, marijuana use, cigarette use, and binge drinking were associated with Time 2 marijuana, cigarette, and binge drinking, respectively. Of the following clinical factors, receipt of more intensive cancer treatment was associated with decreased tobacco use. All other psychosocial and clinical factors analyzed were not associated with any increase or decrease in substance use. Conclusions: A greater emphasis on early health education efforts regarding the health risks of tobacco, alcohol, and marijuana use is needed in this at-risk population.

Smoking and Cannabis Use among Childhood Cancer Survivors: Results of the French Childhood Cancer Survivor Study

BACKGROUND

Unhealthy behaviors among childhood cancer survivors increase the risks for cancer treatment adverse effects. We aimed to assess tobacco and cannabis use prevalence in this population and to identify factors associated with these consumptions.

METHODS

This study involved 2,887 5-year survivors from the French childhood cancer survivor study (FCCSS) cohort. Data on health behaviors were compared with those of controls from the general population. Associations of current smoking and cannabis use with clinical features, sociodemographic characteristics, and health-related quality of life (QOL) were investigated using multivariable logistic regressions.

RESULTS

Prevalence for tobacco use was lower in survivors (26%) than in controls (41%, P < 0.001). Among current smokers, survivors smoked more cigarettes per day and started at a younger age than controls. Women, college graduates, older, married, and CNS tumor survivors, as well as those who received chemotherapy and thoracic radiation therapy, were less likely to be smokers and/or cannabis consumers than others. Participants with a poor mental QOL were more likely to smoke.

CONCLUSIONS

Preventive interventions and cessation programs must be carried out as early as possible in survivors' life, especially among young males with low educational level and poor mental health.

IMPACT

This study brings new insights to health behaviors among childhood cancer survivors from a population with high rates of smoking and cannabis use.

The State of the Science on Cancer Diagnosis as a "Teachable Moment" for Smoking Cessation: A Scoping Review

Theoretically, cancer diagnosis has potential to spur health behavior changes in physical activity, diet, substance use, medication adherence and the like. The Teachable Moment heuristic is a parsimonious, transtheoretical framework for understanding the conditions under which behavior change might occur, with constructs that include affective, cognitive, and social factors. Application of the Teachable Moment to smoking cessation after cancer diagnosis might aid selection of predictors in observational studies and inform how to optimally design interventions to promote quit attempts and sustain abstinence, as many smoking cessation interventions for cancer survivors do not yield positive outcomes. This scoping review of 47 studies that span nearly 20 years of literature examines measurement of the Teachable Moment constructs and what empirical support they have in explaining cancer survivors' smoking behavior. From this review, it appears the construct of affective response is more widely explored than risk perceptions, social role, and self-concept. Strong, negative affective responses (e.g., anxiety, general distress) may be a powerful contributor to continued smoking after cancer diagnosis. Risk perceptions may also play a role in smoking behavior, such that never and former smokers espouse stronger perceptions of smoking-related risks than current smokers. Finally, due to a paucity of studies, the role of cancer survivors' self-concept (e.g., identity as a "cancer survivor") and changes in their social role (e.g., employee, athlete) are unclear contributors to their smoking behavior. In summary, the Teachable Moment holds promise in its application to smoking cessation after cancer diagnosis, though more direct research is needed.

A cross-sectional examination of caregiver mental health and childhood cancer survivors' tobacco, alcohol, and marijuana use

PURPOSE

As childhood cancer survivors (CCS) age, they face numerous long-term consequences, or late effects, from their cancer treatments. Late effects may be mitigated by health-promoting behaviors, including the avoidance of substance use. CCS with greater depression symptomology have reported greater substance use, but whether their habits are associated with the mental health of their caregivers is unknown. The aim of this study was to examine caregiver psychosocial correlates of CCS substance use.

METHODS

This study utilizes data from the Project Forward pilot study, which collected data from 129 CCS-caregiver dyads (CCS mean age = 19.43, SD = 2.78; years since diagnosis = 7.62, SD = 2.06) from two large hospitals in Los Angeles County. CCS provided self-reported information on substance use, while caregivers self-reported on posttraumatic stress symptomatology (PTSS) associated with their child's cancer and current depressive symptoms.

RESULTS

Among CCS, prior 30-day tobacco, marijuana, binge drinking, and polysubstance use were 12.50%, 14.17%, 13.18%, and 12.40%. In multivariable logistic regression models, caregiver PTSS was independently positively associated with CCS tobacco use. No other significant relationships between caregiver mental health (PTSS or depressive symptoms) and CCS substance use were observed.

CONCLUSION

These findings suggest that caregiver PTSS is partially associated with CCS behavioral health. Survivorship care may improve tobacco use prevention efforts by incorporating family or caregiver mental health needs. Future research should examine the potential mediating effect of CCS mental health, including depressive symptoms, on this relationship.

Substance use, substance use disorders, and treatment in adolescent and young adult cancer survivors-Results from a national survey

BACKGROUND

Substance use can exacerbate cancer-related morbidity and mortality in adolescent/young adult (AYA) cancer survivors and place them at increased risk for adverse health outcomes. The objective of this study was to assess substance use, misuse, and substance use disorders [SUDs], as well as receipt of treatment for SUDs, among AYA cancer survivors.

METHODS

The authors used data from the National Survey of Drug Use and Health (2015-2018) to identify a nationally representative sample of AYAs aged 12 to 34 years. Outcomes assessed past-year tobacco, alcohol, marijuana, and illicit drug use; misuse of prescription opioids; SUDs; and SUD treatment. Multiple logistic regression was estimated to compare outcomes between 832 AYAs who reported a cancer history (survivors) and 140,826 AYAs who did not, adjusting sequentially for sociodemographic characteristics and health status.

RESULTS

In regressions adjusting for sociodemographic characteristics, survivors were more likely than a noncancer comparison group of peers to use alcohol (6% relative increase; P = .048) and illicit drugs (34% relative increase; P = .012), to misuse prescription opioids (59% relative increase; P < .001), and to have a marijuana (67% relative increase; P = .011), illicit drug (77% relative increase; P < .001), or prescription opioid (67% relative increase; P = .048) SUD. When further adjusting for health status, survivors were still 41% more likely (P < .001) to misuse prescription opioids than noncancer peers. Among those with SUDs, survivors were more likely than peers to receive treatment (unadjusted, 21.5% vs 8.0%; adjusted, P < .05).

CONCLUSIONS

AYA survivors were as likely as or more likely than noncancer peers to report substance use problems. These findings underscore the importance of interventions to reduce substance use and improve SUD treatment among AYA cancer survivors.

LAY SUMMARY

The authors assessed substance use, misuse, and substance use disorders, as well as the receipt of treatment for substance use disorders, among adolescent and young adult (AYA) cancer survivors. In a nationally representative AYA sample, cancer survivors, despite their increased risk for morbidity and early mortality, were as likely as or more likely than peers without cancer to experience substance use problems. In particular, survivors had a significantly higher rate of prescription opioid misuse than peers. However, only 1 in 5 AYA survivors who experienced substance use disorders received treatment. These findings underscore the importance of interventions toward reducing substance use and improving access to treatment among AYA survivors.

Associations Among Health Behaviors and Psychosocial Outcomes in Adolescent and Young Adult Cancer Survivors

Purpose: Adolescents and young adults (AYA) experience challenges both during and after their cancer treatment. Health behaviors are important contributors to health, yet little research examines health behaviors in AYA cancer survivors. We examined frequencies of health behaviors and associations between health behaviors, psychosocial, and clinical factors in AYA cancer survivors. Methods: Participants were survivors of AYA cancer (n = 60; 38.3% male; mean age = 25.3 years [standard deviation, SD = 4.6]; mean years since therapy completion = 9.0 [SD = 4.2]) from the Alberta Children's Hospital (ACH). Survivors were 13-21 years old at the time of diagnosis. Measures included demographic and clinical data, and the ACH Long-Term Survivor's Questionnaire. Health behaviors were compared with a control group (n = 600) using data from the 2017 Canadian Community Health Survey. Frequencies, conditional logistic regression, and logistic regression analyses were conducted. Results: Compared with controls, survivors reported engaging in physical activity (91.5% vs. 87.5%; odds ratio [OR] = 0.87, 95% confidence interval [CI] = 0.34-2.24; p = 0.77), smoking tobacco (15.3% vs. 19.7%; OR = 1.85, 95% CI = 0.89-3.85; p = 0.10), and street drug use (27.6% vs. 36.5%; OR = 1.60, 95% CI = 0.88-2.91; p = 0.12) at the same rate. Survivors reported binge drinking significantly less (61.0% vs. 76.6%; OR = 0.53, 95% CI = 0.30-0.92; p = 0.024) than controls. Logistic regression analyses revealed a significant model predicting binge drinking [χ²(5, 58) = 23.17, p < 0.001] with greater time off treatment, fear of another health condition, and higher mean body mass index emerging as significant predictors. Conclusion: AYA cancer survivors engage in risky health behaviors at rates similar to their peers. Further research is needed to understand factors mediating survivors' decision to participate in risky health behaviors.

Family and parent-child relationship correlates of pediatric cancer survivors' substance use

OBJECTIVE

The primary aims of this research were to examine substance use among adolescent and young adult survivors of pediatric cancer (AYA survivors) and AYA without a history of chronic or life threatening illness (AYA comparisons) and to explore links between demographic, medical, caregiver-AYA, and family system factors with AYA substance use patterns.

METHODS

Participants included 289 AYA (survivors, n = 171; comparisons = 118; 51% female; M_age = 17.15, SD_age = 2.86) and their caregivers (M_age = 46.54, SD_age = 6.81; 88% mothers). AYA and caregivers completed the family environment scale, and caregivers completed the parenting relationship questionnaire at the initial assessment. Two years later, AYA completed an assessment of substance use. Chi-square and frequency analyses were used to compare differences in substance use among AYA survivors and comparisons. Multivariate analysis of variance was used to examine links between AYA substance use patterns with family and caregiver-AYA system level factors.

RESULTS

Patterns of substance use did not differ between AYA survivors and comparisons. AYA survivors were more likely to report polysubstance use if caregivers endorsed problematic caregiver-AYA relationship patterns. Family functioning and caregiver relationship patterns did not predict AYA comparison substance use.

CONCLUSION

AYA survivors were just as likely as AYA comparisons to engage in substance use, increasing their vulnerability to problematic health outcomes. Findings indicate that the role caregiver-AYA relationship patterns may have on youth at risk for substance use and potential mechanisms for future intervention.

Childhood Cancer Survivorship: Daily Challenges

Survivors of childhood cancer are at risk of experiencing fatigue, pain, lower levels of physical activity, increased engagement in risky health behavior, and poor social adjustment, after finishing treatment. Risks are more pronounced for survivors of specific diagnoses or receiving specific treatment protocols. Interventions to address these outcomes are in their infancy. Future research should focus on exploring the antecedents and consequences of these outcomes. In the meantime, researchers and cancer centers should attempt to provide high-quality and accessible health information to survivors through various media outlets to encourage healthy behaviors.

Association of Demographic and Cancer-Specific Factors on Health Behavior Recommendations Specific to Cancer Prevention and Control Among Adolescent and Young Adult Survivors of Childhood Cancer

Purpose: Adolescent and young adult survivors of childhood cancer (AYA) are at risk for long-term health problems that are exacerbated by not meeting health behavior recommendations (e.g., exercise). To identify AYA at risk for not meeting health behavior recommendations, we explored demographic (e.g., age) and cancer-specific (e.g., intensity of treatment) factors associated with not meeting specific health behavior recommendations that have implications for cancer prevention and control. Methods: Regression (linear/binary) was used to examine demographic and cancer-specific associates regarding fruit/vegetable intake, binge drinking, sleep duration, sunscreen use, tobacco use, and physical activity among 307 AYA (M^age = 20.33, range = 15-34) across three combined studies, treated at a pediatric cancer center. Health behavior measures were adapted from The Health Behaviors Survey and the Youth Risk Behavior Surveillance System questionnaire. Results: AYA in general did not meet health behavior recommendations. Compared with AYA with public insurance, AYA with private insurance (β = -0.19, p < 0.01) were more likely to meet multiple health behavior recommendations. AYA at greatest risk for not meeting specific health behaviors were more likely to be diagnosed in middle childhood (11.35^years) compared with early childhood (8.38^years), be closer to diagnosis (8.77^years vs. 11.76^years) and closer to treatment completion (6.97^years vs. 9.91^years), and have a solid tumor (32.7%) compared with a brain tumor (10.6%). Conclusion: Not meeting health behavior recommendations is common among AYA survivors of childhood cancer. Early education in the context of survivorship care is critical to provide teachable moments to AYA; such interventions might impact future long-term health and reduce risk for secondary cancers.

Estimating cancer treatment intensity from SEER cancer registry data: methods and implications for population-based registry studies of pediatric cancers

OBJECTIVE

The Intensity of Treatment Rating (ITR) Scale condenses treatment and clinical characteristics into a single measure to study treatment effects on downstream health outcomes across cancer types. This rating was originally developed for clinicians to determine from medical charts. However, large studies are often unable to access medical charts for all study participants. We developed and tested a method of estimating treatment intensity (TI) using cancer registry and patient self-reported data.

METHODS

We estimated two versions of TI for a cohort of pediatric cancer survivors-one utilized information solely available from cancer registry variables (TIR) and the other included registry and self-reported information (TIS) from survey participants. In a subset of cases (n = 135) for whom the gold standard TI (TIC) was known, both TIR and TIS were compared to TIC by calculating percent agreement and weighted Cohen's kappa, overall and within cancer subtypes.

RESULTS

In comparison to TIC, 71% of TI scores from both methods were in agreement (k = 0.61 TIR/0.54 TIS). Among subgroups, agreement ranged from lowest (46% TIR/39% TIS) for non-defined tumors (e.g., "Tumor-other"), to highest (94% TIR/94% TIS) for acute lymphoblastic leukemia (ALL).

CONCLUSIONS

We developed a methodology to estimate TI for pediatric cancer research when medical chart review is not possible. High reliability was observed for ALL, the most common pediatric cancer. Additional validation is needed among a larger sample of other cancer subgroups. The ability to estimate TI from cancer registry data would assist with monitoring effects of treatment during survivorship in registry-based epidemiological studies.

Coping Strategies and Factors Related to Problematic Substance Use and Behavioral Addictions Among Adolescents and Young Adults with Cancer

Purpose: This study aimed to explore and identify the factors associated with problematic substance use (alcohol, tobacco, and cannabis) and behavioral addictions (internet and eating disorders) over time in adolescents and young adults (AYAs) treated for cancer. Methods: AYAs newly diagnosed with cancer, 15-25 years of age, completed a questionnaire during their hospitalization (T1), assessing their consumption of alcohol, tobacco, and cannabis (The Alcohol Use Disorders Identification Test; The Smoking Behavior Questionnaire; and The Cannabis Abuse Screening Test), their internet use (The Internet Addiction Test), their body preoccupations (The Eating Attitudes Test), as well as their coping strategies (Brief COPE) and emotional adjustment (The Hospital Anxiety and Depression Scale). Questionnaires were completed again 6 months later (T2). Results: Seventy-three AYAs were included at T1 and 21 AYAs at T2. Nearly one out of two (46.58%) AYAs had a problematic substance use or behavioral addiction after cancer diagnosis (T1). Problematic use of internet was frequently reported (23.29%), as well as harmful alcohol consumption or addiction (16.44%) and cannabis dependence (12.33%). The main factor related to problematic substance use was being older, while the main factor related to behavioral addiction was having a higher anxiety score. Substance use as a coping strategy was used more frequently by AYAs with problematic substance use and emotional support as a coping strategy was used more frequently by AYAs with a behavioral addiction. Conclusions: High rates of problematic substance use and behavioral addiction were reported in our sample. AYAs surveyed had high problematic use of cannabis and high internet use. Attention to substance use and addictive behaviors is recommended to ensure optimal care.

Childhood Cancer Survivorship and Substance Use Behaviors: A Matched Case-Control Study Among Hispanic Adolescents and Young Adults

PURPOSE

This case-control study compared substance use behaviors between Hispanic adolescent and young adult survivors of childhood cancers (cases) and a community sample of participants without cancer (controls).

METHODS

A total of 100 cases were matched to controls (200 participants) one to one by ethnicity, age, and sex (mean age at survey 19.27, standard deviation = 1.92). Differences in self-reported previous 30-day use of tobacco, alcohol, binge drinking of alcohol, and marijuana were examined using conditional multivariable logistic regression.

RESULTS

The odds of tobacco, alcohol, binge drinking, and marijuana use were significantly lower for cases than for controls (all p's <.05). When stratified by age, cases (vs. controls) under 21 years of age reported lower levels of substance use (all p's <.05), whereas differences over the age of 21 were nonsignificant.

CONCLUSIONS

Lower levels of substance use among Hispanic adolescent and young adult survivors of childhood cancers (vs. controls) are most apparent at younger ages. Future work needs to examine a potential delay in initiation of use among survivors.

Depressive Symptoms and Quality of Life Among Adolescent and Young Adult Cancer Survivors: Impact of Gender and Latino Culture

Ethnic and sex variations in depressive symptoms and quality of life (QOL) among adolescent and young adult (AYA) childhood cancer survivors were explored among a sample of Latino and non-Latino childhood cancer survivors (CCSs) (n = 194) treated at hospitals in Los Angeles County. Latinos scored higher in depressive symptoms and lower in QOL when compared with non-Latinos. Males had higher depressive symptoms. Among Latinos, higher levels of acculturation were associated with depression and a poorer QOL, and we found that more acculturated Latino males were more likely to have meaningful levels of depression than less acculturated males or females. Interventions addressing depressive symptoms may be most needed for Hispanic male CCSs.

Factors influencing risk-based care of the childhood cancer survivor in the 21st century

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

Alcohol and Cancer: A Statement of the American Society of Clinical Oncology

Alcohol drinking is an established risk factor for several malignancies, and it is a potentially modifiable risk factor for cancer. The Cancer Prevention Committee of the American Society of Clinical Oncology (ASCO) believes that a proactive stance by the Society to minimize excessive exposure to alcohol has important implications for cancer prevention. In addition, the role of alcohol drinking on outcomes in patients with cancer is in its formative stages, and ASCO can play a key role by generating a research agenda. Also, ASCO could provide needed leadership in the cancer community on this issue. In the issuance of this statement, ASCO joins a growing number of international organizations by establishing a platform to support effective public health strategies in this area. The goals of this statement are to:

• Promote public education about the risks between alcohol abuse and certain types of cancer;

• Support policy efforts to reduce the risk of cancer through evidence-based strategies that prevent excessive use of alcohol;

• Provide education to oncology providers about the influence of excessive alcohol use and cancer risks and treatment complications, including clarification of conflicting evidence; and

• Identify areas of needed research regarding the relationship between alcohol use and cancer risk and outcomes.

Development of depression in survivors of childhood and adolescent cancer: a multi-level life course conceptual framework

As therapeutic and supportive care interventions become increasingly effective, growing numbers of childhood and adolescent cancer survivors face a myriad of physical and psychological sequelae secondary to their disease and treatment. Mental health issues, in particular, present a significant problem in this unique patient population, with depression affecting a sizable number of childhood and adolescent cancer survivors. Multiple key determinants impact a survivor's risk of developing depression, with variables traversing across biologic, individual, family, community, and global levels, as well as spanning throughout the life course of human development from the preconception and prenatal periods to adulthood. A multi-level life course conceptual model offers a valuable framework to identify and organize the diverse variables that modulate the risk of developing depression in survivors of childhood and adolescent cancer. This review describes the first multi-level life course perspective applied to development of depression in childhood and adolescent cancer survivors. This conceptual framework may be used to guide the investigation of mental health interventions for SCACs to ensure that key determinants of depression occurrence are adequately addressed across various levels and throughout the life trajectory.
