Social health, activity behaviors, and quality of life among young adult cancer survivors: Protocol for a prospective observational study

Approximately 85,000 adolescent and young adults (AYAs; age 15–39) are diagnosed with cancer in the United States annually. Experiencing a cancer diagnosis as an AYA can substantially impact social connections and social health. This paper describes the design and protocol of an observational study to prospectively assess social health and its association with physical activity and quality of life among AYAs after a cancer diagnosis. The study uses a longitudinal observational design to prospectively explore the relationships between social health and activity behaviors (physical activity and sedentary time) at four clinically significant timepoints over the course of 12 months among AYAs newly diagnosed with cancer. Patients are recruited at three hospitals and surveyed at each time period. Multiple dimensions of social health are assessed including social support, social roles, loneliness, social anxiety, and social networks. A wrist accelerometer is worn for one week at each assessment period. Change in social network structures will be analyzed using egocentric social network analysis. Structural equation models will be fitted to analyze the relationship between social constructs and physical activity. Findings from this study will address gaps in our understanding of the impact of a cancer diagnosis on multiple dimensions of social health for AYAs and the potential role social factors play in physical activity and quality of life. Understanding these processes will inform age-tailored interventions to improve health and quality of life outcomes for this at-risk population.

Balancing Fertility Preservation and Treatment Efficacy in (Neo)adjuvant Therapy for Adolescent and Young Adult Breast Cancer Patients: a Narrative Review.

Adolescent and young adult (AYA) breast cancer survivors face a significant risk of infertility due to the gonadotoxic effects of (neo)adjuvant therapy, which complicates their ability to conceive post-treatment. While (neo)adjuvant therapy primarily aims to improve recurrence-free and overall survival, fertility preservation strategies should also be considered for young patients. This narrative review explores recent advancements in fertility preservation techniques, such as oocyte, embryo, and ovarian tissue cryopreservation, and evaluates the feasibility of modifying breast cancer (neo)adjuvant therapy to preserve fertility without compromising survival outcomes. Our review highlights that clinical trials with co-primary endpoints of oncological safety and fertility preservation are limited, and substituting standard treatment regimens solely for fertility preservation is currently not recommended. Nevertheless, new clinical studies have emerged that either exclude highly ovarian-toxic agents, such as cyclophosphamide, or omit adjuvant therapy altogether, even if fertility preservation is not their primary endpoint. Unfortunately, many of these trials have not evaluated ovarian toxicity. Notably, since 2020, major oncology organizations, including the American Society of Clinical Oncology (ASCO), the European Society of Medical Oncology (ESMO) have advocated for the routine assessment of ovarian toxicity in all clinical trials. The review underscores the importance of incorporating ovarian toxicity as a standard endpoint in future trials involving premenopausal breast cancer patients to identify treatment regimens that can effectively balance fertility preservation with treatment efficacy.

Awareness and implementation of comprehensive genomic profiling and cancer support for adolescents and young adults among healthcare professionals in Osaka, Japan.

Comprehensive genomic profiling (CGP) and specialized support for adolescent and young adult (AYA) cancer patients are crucial yet underexplored areas of healthcare in Japan. This study investigated awareness of CGP testing and support for AYA cancer patients among healthcare professionals in Osaka. An anonymous online survey was conducted from 31 January to 31 March 2024. The survey targeted all staff, including doctors, nurses, technicians, pharmacists and others, from eight Toyono Medical Area Cancer Medical Network Council hospitals. The survey included questions on basic demographics, awareness of CGP testing and support provided to patients with AYA cancer. Among the 720 respondents, 41.9% were aware of CGP testing, while 20.3% were unaware. Regarding AYA cancer, 60.7% were aware and 14.3% were unaware. Only 7.5% had frequent contact with AYA patients and 96.8% recognized the need for education and information. Awareness of CGP was greater among doctors (72.5%) than among other professionals (34.4%); similarly, AYA cancer awareness was higher among doctors (73.9%) than among other professionals (57.7%). CGP awareness among doctors varied by years of experience and institutional type, being highest in core and cooperative hospitals (80 and 78.6%, respectively) and among doctors with more than 21years of experience (90%). This study reveals significant gaps in CGP and AYA cancer awareness among healthcare professionals in Osaka, Japan, with doctors demonstrating higher awareness levels than other professionals. There is a pressing need for targeted educational programs to enhance the understanding and implementation of CGP and support AYA cancer patients.

Dynamin-1 is a potential mediator in cancer-related cognitive impairment

Dynamin-1 (DNM1) is crucial for synaptic activity, neurotransmission, and associative memory, positioning it as a potential biomarker of cancer-related cognitive impairment (CRCI), a neurological consequence of cancer treatment characterized by memory loss, poor concentration, and impaired executive function. Through a stepwise approach, this study investigated the role of DNM1 in CRCI pathogenesis, incorporating both human data and animal models. The human study recruited newly diagnosed, chemotherapy-naïve adolescent and young adult cancer and non-cancer controls to complete a cognitive instrument (FACT-Cog) and blood draws for up to three time points. Following that, a syngeneic young-adult WT (C57BL/6) female mouse model of breast cancer chemobrain was developed to study DNM1 expression in the hippocampus. Samples from eighty-six participants with 30 adolescent and young adult (AYA) cancer and 56 non-cancer participants were analyzed. DNM1 levels were 32 ​% lower (P ​= ​0.041) among cancer participants compared to non-cancer prior to treatment. After receiving cytotoxic treatment, cognitively impaired cancer patients were found to have 46 ​% lower DNM1 levels than those without impairment (P ​= ​0.049). In murine breast cancer-bearing mice receiving chemotherapy, we found a greater than 40 ​% decline (P ​< ​0.0001) in DNM1 immunoreactivity in the hippocampal CA1 and CA3 subregions concurrent with a deterioration in spatial recognition memory (P ​< ​0.02), compared to control mice without exposure to cancer and chemotherapy. Consistently observed in both human and animal studies, the downregulation of DNM1 is linked with the onset of CRCI. DNM1 might be a biomarker and therapeutic target for CRCI.

Knowledge, Attitudes and Practices of Teenagers and Young Adults About Breast Cancer – A Systematic Review

This systematic review seeks to identify studies that examine the level of awareness, attitudes, and practices regarding breast cancer in adolescents and young adults, including their engagement in self-examination. The publications were retrieved from the PUBMED and SCOPUS databases in accordance with the 2020 guidelines for systematic reviews and meta-analyses (PRISMA).

Substance Use in Adolescent and Young Adult Cancer Survivors: An Integrative Review.

The adolescent and young adult (AYA) ages are a time when individuals are susceptible to risky behaviors, including binge drinking, tobacco, marijuana, and illicit drug use. AYAs are at an increased risk for developing chronic health problems compared with their healthy peers, and substance use can pose additional risks. The purpose of this review is to compare substance use in AYAs with their healthy peers and identify contributing factors. A literature search was conducted of PubMed, Scopus, and OVID databases using keywords substance*, adolescent*, adolescence*, teens*, teenager*, young adult*, pediatric*, childhood*, cancer*, and oncology*. The initial search yielded 148 articles. Inclusion criteria specified English language and articles from January 1, 2013, to December 31, 2023. Studies were excluded if they did not include participants aged <18 years and without a noncancer comparison group. Five relevant articles were included after review and appraisal. Substance use was examined by substance use type and contributing factors, including caregiver-AYA relations, age, and depression/coping. Findings were mixed for substance use, including tobacco and alcohol use. Findings indicate no consistent pattern-substance use was both more and less common in AYAs than in their noncancer peers, or substance use did not differ between AYAs and their noncancer peers. With mixed results, each study identified some level of substance use in AYAs. Given this knowledge, when treating AYAs, providers should be diligent about screening for substance use during each visit. AYAs should be educated about the risk of substance use, especially as a vulnerable, at-risk population.

Young adult Latino testicular cancer survivors: a pilot study of Goal-focused Emotion regulation Therapy (GET)

PurposeYoung adult Latino testicular cancer survivors experience adverse impacts after treatment. We developed Goal-focused Emotion regulation Therapy (GET) to improve distress symptoms, goal navigation skills, and emotion regulation. This open pilot trial extended GET to Latino young adult survivors of testicular cancer and assessed feasibility and tolerability as well as changes in anxiety and depressive symptoms. Secondary outcomes included goal navigation, emotion regulation, and components of hope-related goal processes (i.e., agency and pathway mapping). To assess the extent to which GET is culturally congruent or in need of adaptation, the influence of simpatía and acculturative stress were also examined.MethodsThirty-five eligible young adult (age 18–39) survivors treated with chemotherapy were enrolled and assessed at baseline. Study acceptability, tolerability, and therapeutic alliance were examined. Preliminary efficacy was evaluated for changes in anxiety and depressive symptoms as well as psychological processes (goal navigation, agency, goal pathway skill, and emotion regulation) from baseline to immediate post- and 3-month post-intervention.ResultsAmong the 35 men assessed at baseline, 54% initiated intervention sessions. Among these, 94.7% completed all study procedures. Helpfulness ratings of intervention components and therapeutic alliance scores were strong. Repeated measures ANOVA revealed significant reductions in anxiety and depressive symptoms from pre- to post-intervention with sustained change at the 3-month follow-up. Favorable patterns of change were also observed in GET-related psychological processes. Simpatía was associated with less depressive symptoms at post-intervention, but not change in anxiety. Acculturative stress was associated with increased anxiety and depressive symptoms over time.ConclusionGET is a feasible and acceptable intervention for reducing adverse outcomes after testicular cancer for young adult Latino men. Results should be considered preliminary but suggest meaningful changes in emotional and psychological outcomes.

The Triglycerides - Glucose Index: An independent predictor of late subclinical cardiotoxicity in adult survivors of childhood, adolescent and young adult cancer

Abstract Introduction The Triglycerides - Glucose index (TyG index) has been identified as a reliable alternative for estimating insulin resistance (IR). Numerous recent studies have provided strong statistical evidence suggesting that this index is associated with the development and prognosis of cardiovascular pathologies. Objectives The aim of this study was to investigate the predictive role of the TyG index on the decrease in left ventricular longitudinal global strain (GLS) assessed on two-dimensional echocardiography in asymptomatic adult survivors of childhood, adolescent and young adult cancer. Methods The study included patients aged 18 years and older, asymptomatic cardiovascular survivors of childhood, adolescent and young adult cancer treated with anthracyclines with or without mediastinal radiotherapy. Anthropometric characteristics, cardiovascular risk factors and cancer treatment-related characteristics were collected. The TyG index was calculated using the formula: ln [fasting triglycerides (mg/dl) × fasting glucose (mg/dl)/2]. GLS was assessed and expressed as an absolute value. A GLS equal to 17.3% was retained as the threshold value after calculation in a referent group matched to patients according to age and gender. Cardiac biomarkers GDF 15, ultra-sensitive troponin I and NT-proBNP levels were measured in addition to fasting blood glucose and lipid profiles. Multivariate analysis using linear regression was performed to identify associations between these different parameters. Results A total of 105 cancer survivors from childhood, adolescence and young adulthood were included. The sex ratio was 1.3. The mean age of the patients was 25 years, the mean time since completion of cancer treatment was 10.6 years, the mean cumulative doses of anthracyclines and mediastinal radiotherapy were successively 245.75 ± 75.14 mg/m2 and 34.6 ± 6.19 Gy. Mean GLS was 18.5 ± 2.83%, mean LVEF 60.6 ± 5.69%. None of the patients had any known diabetes or treatment to lower blood glucose or triglyceride levels. No patient had a history of cardiovascular disease. In the univariate study, the factors associated with lower GLS were patient age at recruitment (p = 0.03), mean time since completion of cancer treatment when this was greater than ten years (p = 0.005), dyslipidemia (p = 0.012), obesity (p = 0.037) and TyG (p = 0.037). In multivariate analysis, lower GLS was related to mean time since completion of cancer treatment (p = 0.015) and TyG index (p = 0.002). Conclusion Our results suggest that the TyG index, as a simple and inexpensive marker of insulin resistance, could help identify cancer survivors from childhood, adolescence and young adulthood who would be at risk of subclinical cardiac dysfunction. Prospective studies with larger numbers are needed to confirm these findings.

Feasibility Trial of an Online Expressive Writing Intervention for Young Adult Cancer Survivors.

Purpose: Many young adult (YA) breast cancer survivors (BCS) experience psychosocial distress during and after treatment, but do not utilize supportive care resources to maximize their health outcomes. The purpose of this pilot study was to test the feasibility and acceptability of a brief, internet-based expressive writing (EW) intervention intended to improve psychosocial health among YA BCS. Methods: Thirty YA BCS were remotely recruited via a hospital patient database and randomly assigned to the EW (n = 20) or neutral writing (n = 10) group. The EW intervention included delivery of positive messages and a weekly 30-minute EW activity for 3 weeks. Feasibility, acceptability, patient-reported satisfaction, and health outcomes were evaluated at baseline and 1-month follow-up. Results: The database-focused recruitment strategies (40% response) appeared to be feasible. Almost all (93%) participants adhered to at least one writing task and 67% to at least two writing tasks. Participants perceived the study as enjoyable and helpful for reducing stress. The difference in QOL of the intervention versus control group was medium to large (d = 0.73). Conclusion: This is the first study to test the feasibility of an internet-based EW for YA BCS. The online EW pilot intervention demonstrated evidence of feasibility and acceptability to YA BCS; its potential to improve health outcomes should be evaluated in an adequately powered prospective randomized controlled trial (RCT). Online EW may be offered to YA BCS in low-resource settings to address their unique physical and psychological challenges.

Unveiling the heartbeat of hope: exploring cardiovascular morbidity, mortality, and socioeconomic threads in 65,173 Child, Adolescent, and Young Adult (caya) cancer patients

Abstract Background Despite significant progress in managing cancer in children, adolescents, and young adults (CAYAs), persistent complications impact their quality of life with some being severe or life-threatening.(1,2) Long-term outcomes depend on common risk factors for malignancy and cardiovascular diseases (CVD) that overlap, and treatments are known to increase the risk for CVD. (3,4) Healthcare inequality due to socioeconomic status is omnipresent and may significantly impact outcomes. Purpose This study aims to comprehensively cover morbidity, mortality, demographic, and socioeconomic factors among CAYAs and investigate their impact on cardiovascular outcomes. Methods This retrospective matched cohort study included the entire Swedish population under 25 with cancer from 1958 to 2021. The study population was identified from the National Board of Health and Welfare's Cancer Register, with controls paired 1:5 based on age, sex, and residence. Multiple registers provided data on morbidity, mortality, and demographics. Results Covering 63 years, identified 65,173 CAYAs (1.24 million patient-years) and matched with 312,935 controls (7.45 million person-years), a total of 378,108 individuals (74% females). The mean follow-up was 19.5 (SD16.9) years for CAYAs, and 23.8 (16.8) for controls, (p&amp;lt;0.001). At the end of the study, the median age of CAYAs was 33.4 (IQR 27.9) years and controls 39.2 (28.3) (p&amp;lt;0.0001), with an age span of &amp;lt;1-88 years in both groups. CVD was detected in 16.9 % of the CAYAs, representing a 1.21-time elevated risk (95% CI 1.18-1.23, p&amp;lt;0.0001) compared to controls. CAYAs had a higher mortality rate, and 5-years survivors lived a mean of 26.9 years shorter than controls. CV mortality was also increased in CAYAs, (1.9% compared to 0.7% in controls) but at a higher age, although at a mean of 22.8 years younger than their controls. The 5-year survivors were older at CV mortality and lived in mean 6.5 years shorter than controls (p&amp;lt;0.0001). After adjusting for socioeconomic factors, individuals born outside Europe and those with greater sick leave had a higher mortality risk, while education and marriage showed a beneficial association with mortality. (p&amp;lt;0.0001). Interpretation The Rebuc study, spanning six decades, revealed a significantly increased risk of serious complications among young cancer patients in Sweden. Not only do young cancer patient survivors face a significantly higher risk for cardiovascular disease, but the higher mortality risk before middle age also underscores the severity of the health challenges they confront. Furthermore, these young individuals are more susceptible to socioeconomic factors that may adversely affect their survival.

Availability of Adolescent and Young Adult-Specific Sexual and Reproductive Health Programs and Resources: A Review of the Websites of National Cancer Institute-Designated Cancer Centers.

Adolescent and young adult (AYA) cancer survivors often search online for information about cancer-related sexual and reproductive health concerns. A review of the websites of National Cancer Institute-designated cancer centers (n = 9) and comprehensive cancer centers (n = 58) was conducted to identify the presence of AYA-specific sexual and reproductive health programming and resources. No AYA-specific sexual health programs were found. Oncofertility programs were presented on 56% (n = 5) of cancer centers and 50% (n = 29) of comprehensive cancer center websites. As the population grows, it is imperative that cancer centers provide services to meet AYAs' sexual and reproductive health needs and highlight these services on their websites.

Health-related quality of life and supportive care needs in young adult cancer survivors-a longitudinal population-based study.

To examine health-related quality of life (HRQoL) and supportive care needs among young adult (YA) cancer survivors up to 3years post-diagnosis. A national cohort of individuals diagnosed at 18-39years with breast, cervical, ovarian, or testicular cancer, lymphoma or brain tumor was approached with surveys at 1.5 (n = 1010, response rate 67%) and 3 (n = 722) years post-diagnosis. HRQoL was measured using the EORTC QLQ-C30. Scores were dichotomized using cut-off scores to predict supportive care needs in the Supportive Care Needs Survey-Long Form 59 (SCNS-LF59). Swedish cancer quality registers provided clinical data. Factors predicting need of support at 1.5 and 3years post-diagnosis were identified using logistic regression. HRQoL improvements over time were trivial to small. At both time points, a majority of respondents rated HRQoL levels indicating supportive care needs. At 1.5years post-diagnosis, the risk of having support needs was lower among survivors with testicular cancer (compared to lymphoma) or university-level education, and higher among those on treatment (predominantly endocrine therapy). At 3years post-diagnosis, when controlling for previous HRQoL scores, most correlations persisted, and poor self-rated household economy and chronic health conditions were additionally associated with supportive care needs. A majority of YAs diagnosed with cancer rate HRQoL at levels indicating support needs up to 3years post-diagnosis. Testicular cancer survivors are at lower risk of having support needs. Concurrent health conditions and poor finances are linked to lower HRQoL. More efforts are needed to provide adequate, age-appropriate support to YA cancer survivors.

Associations Between Characteristics of Adolescent and Young Adult Cancer Survivors and Their Use of Different Social Media Platforms: An Observational Study of Social Media Accounts.

Background: The growing number of adolescent and young adult (AYA) cancer survivors and their unmet needs demand innovative communication and care strategies. This study uses social media data to examine how survivors' demographic and clinical characteristics relate to their social media use. Methods: Data from 300 AYA cancer survivors on six social media sites (YouTube, Instagram, Facebook, TikTok, Reddit, X/formerly Twitter) were collected between August 2022 and March 2023 and analyzed using descriptive statistics and statistical tests (chi-square, Fisher's exact, Welch, Games-Howell post-hoc, logistic regression). Results: Significant differences were observed across platforms for mean current age (p < 0.001) and age at diagnosis (p < 0.001). We also found significant associations between social media type used and current age, age at diagnosis, years since diagnosis, and the timing of social media account creation. AYAs who created their social media account post-diagnosis were less likely to use YouTube (p = 0.003) and more likely to use Facebook (p = 0.009). Treatment completion was associated with increased use of platform X (p = 0.004). Non-White individuals in our sample were less likely to use Facebook (p = 0.008). Significant associations were found between observed sex and platform usage (p < 0.001), with males more likely to use Reddit (p < 0.001) and X (p < 0.001). Conclusions: Significant associations were found between demographic and clinical attributes of AYA cancer survivors and the type of social media they used, suggesting that AYA-specific social media-based interventions should be tailored to subgroup characteristics (e.g., social media type, developmental stage based on age at diagnosis and current age, sex).

Identifying the informational needs and sources of support of Adolescent and Young Adult (AYA) cancer survivors to inform the development of a digital platform.

This study aimed to examine the (age-specific) informational needs and support sources used by Adolescent and Young Adult (AYA) cancer survivors throughout their cancer trajectory and socio-demographic and clinical factors associated with most common AYA-related informational needs. A cross-sectional questionnaire study was conducted among AYA cancer survivors (mean, 10.3 years after diagnosis, SD = 5.6). Informational needs and sources of support were examined via open questions and analyzed via a thematic inductive approach. Responses on informational needs were categorized according to the AYA anamnesis of the Dutch AYA "Young & Cancer" Care Network used in clinical practice. Chi-square and ANOVA tests were performed to assess differences in socio-demographic and clinical characteristics among AYA cancer survivors based on their varying levels of informational needs. In total, 593 AYA cancer survivors were included (mean, 32.2 years at diagnosis, SD = 5.6). Most common informational needs were related to: family and children (23%), fertility and pregnancy (23%), work and reintegration (20%), peers with cancer (13%), and intimacy and sexuality (13%). Females, AYA cancer survivors diagnosed a longer time ago, those with a college/university education, those diagnosed with breast or hematological malignancies, and those treated with chemotherapy were more likely to have AYA-related informational needs. The most often used sources of support were healthcare professionals (76%), family (72%), social life (69%), and websites (47%). AYA cancer survivors have informational needs related to their life stage including topics like family and children, and fertility. Tailored information services and support are needed, including opportunities to connect with peers and support for relatives. By addressing the informational needs and sources of support for AYA cancer survivors, we can improve AYA care programs and empower AYA cancer survivors to better cope with the consequences associated with their disease. This study will help to inform the content of AYA websites and platforms and help AYA cancer survivors, relatives, and healthcare professionals to become more aware of the needs of AYA cancer survivors and facilitate better use of relevant information and support services.

Rectal Cancer in Young Adults: A Single Center Experience.

Purpose: Individuals below the age of 40 make up only 3%-11% of colorectal cancer (CRC) cases. In this study, we aimed to review clinicopathological characteristics of rectal cancer in young adults. Methods: Rectal adenocancer patients aged ≤40 were included in this study from Antalya Training and Research Hospital. A single-arm descriptive study was designed. Results: There were 85 patients in the final analyses (n = 85). The median age was 37 (19-40). Mucinous adenocarcinoma and signet-cell carcinoma rates were 11.8% for each. Twenty patients (24.4%) had high-grade cancer. Fourteen patients (16.5%) had CRC history in a first-degree relative. None of the patients were diagnosed through a screening test. Of the 85 patients, 41 (48.2%) were stage 3 and 23 (27.1%) were stage 4 at the time of diagnosis. Thirty-four (54.8%) of the 62 nonmetastatic patients had neoadjuvant and 27 (43.5%) had adjuvant treatment because of having an upfront surgery before presentation. In the nonmetastatic population, the 5-year disease-free survival rate was 69.7 ± 6.5%. De-novo metastatic underwent chemotherapy, and biological agents were administered when feasible. KRAS mutation rate was 56.5% among metastatic patients. The median progression-free survival for the first-line treatment was 11.2 months (5.7-16.6), and the median overall survival was 22.3 months (15.4-29.1). Conclusion: We demonstrated that rectal cancer is usually diagnosed at late stages in young individuals which is compatible with the previous reports. Low cancer awareness in young patients and their caregivers and adverse histological features were advocated as the reason for the diagnostic delay. However, future studies may elucidate the reason behind the common diagnosis at advanced stages.

Burden landscape of hepatobiliary and pancreatic cancers in Chinese young adults: 30 years' overview and forecasted trends.

Hepatobiliary and pancreatic (HBP) cancers impose a considerable burden on young populations (aged 15 to 49 years), resulting in a substantial number of new cases and fatalities each year. In young populations, the HBP cancers shows extensive variance worldwide and the updated data in China is lacking. To investigate the current status, trends, projections, and underlying risk factors of HBP cancers among young populations in China. The Global Burden of Disease Study 2019 provided data on the annual incidence, mortality, disability-adjusted life years (DALYs), age-standardized incidence rate (ASIR), mortality rate (ASMR), and DALYs rate (ASDR) of HBP cancers in young Chinese adults between 1990 and 2019. Temporal trends were assessed using estimated annual percentage change and hierarchical clustering. Sex-specific mortality and DALYs caused by various risks were analyzed across China and other regions, with future trends until 2035 projected using the Bayesian age-period-cohort model. From 1990 to 2019, incident cases, deaths, DALYs, ASIR, ASMR, and ASDR for liver cancer (LC) in young Chinese individuals decreased, classified into 'significant decrease' group. Conversely, cases of gallbladder and biliary tract cancer and pancreatic cancer rose, categorized as either 'significant increase' or 'minor increase' groups. The contribution of risk factors to mortality and DALYs for HBP tumors increased to varying degrees. Healthy lifestyle behaviors, such as tobacco control, weight management, alcohol moderation, and drug avoidance, could lower HBP cancers incidence. Moreover, except for LC in females, which is likely to initially decline slightly and then rise, the forecasting model predicted that the ASIR and ASMR for all HPB cancers subtypes by gender will increase among young adults. HBP cancers burden among young adults in China is expected to increase until 2035, necessitating lifestyle interventions and targeted treatment strategies to mitigate the public health impact of these cancers.

Vaping behavior among adolescent and young adult cancer survivors: A scoping review.

Adolescent and young adult (AYA) cancer survivors are vulnerable to future health complications and engage in risky health behaviors. Vaping or electronic cigarette use is increasing among AYA, yet little is known about the prevalence in AYA cancer survivors and associated morbidities. The objective of this research was to analyze the current state of the literature on vaping among AYA cancer survivors with scoping review methodology. Eligibility criteria included any vaping among people aged 13-39years with cancer or a history of cancer. Database searches from PubMed, Web of Science, PsycINFO, and Scopus yielded eight cross-sectional studies. Results suggest significant variability, with studies finding 2%-46% of AYA survivors have ever or currently vape. Medical (e.g., late effects), psychosocial (e.g., depression), and demographic correlates (e.g., younger age, male gender), as well as other risky health behaviors (e.g., cigarette smoking) were shown to be associated with vaping. Though the extant research is beginning the task of understanding comorbidities with vaping, few research has focused on those most vulnerable to vaping (survivors under age 18). More research is required to understand AYA survivors' vaping behavior to better understand the significance and implications regarding the growing incidence of vaping among this vulnerable population.

Prevalence of cancer survivors diagnosed during adolescence and young adulthood in the United States.

Adolescent and young adult (AYA) cancer incidence rates are rising, and survivors are at risk for numerous cancer- and treatment-related consequences. Despite growing attention to this population, prevalence estimates are lacking. To estimate the number of individuals living in the United States with a history of cancer diagnosed during the AYA period. Prevalence of cancer survivors diagnosed between the ages of 15 and 39 years was estimated using data from the Surveillance, Epidemiology, and End Results (SEER) program as of January 1, 2020. Limited duration prevalence data were also used to generate complete prevalence by sex, years since diagnosis (0-<1, 1-<5, 5-<10, 10-<15, 15-<20, 20+), and attained age (15-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70+) for the 15 most common AYA cancer sites. There were an estimated 2,111,838 survivors of AYA cancers in the United States as of January 1, 2020. More survivors were female (66%) and long-term (>5 years from diagnosis, 83%) or very long-term survivors (>10 years from diagnosis, 68.8%). A large percentage (44%) were more than 20 years from diagnosis. The most common cancer sites among females were breast (24%) and thyroid cancers (23%) and, among males, testicular cancer (31%). Across the population, the highest percentage of survivors of AYA cancers were 40- to 49-years of age (25.3%). There are over 2.1 million cancer survivors diagnosed in the AYA period who are living in the United States; most are more than 10 years from diagnosis.
