The Burden of Late Effects and Related Risk Factors in Adolescent and Young Adult Cancer Survivors: A Scoping Review

Health-related conditions among long-term cancer survivors diagnosed in adolescence and young adulthood (AYA): results of the SURVAYA study

BACKGROUND

With 5-year survival rates > 85%, gaining insight into the long-term and late health-related conditions of cancer survivors diagnosed in adolescence and young adulthood is of utmost importance to improve their quantity and quality of survival. This study examined the prevalence of and factors associated with, patient-reported health-related conditions and their latency times among long-term adolescent and young adult (AYA) cancer survivors.

METHODS

AYA cancer survivors (5-20 years after diagnosis) were identified by the population-based Netherlands Cancer Registry (NCR), and invited to participate in the SURVAYA questionnaire study. Participants reported the prevalence and date of diagnosis of health-related conditions. Clinical data were retrieved from the NCR.

RESULTS

Three thousand seven hundred seventy-six AYA cancer survivors (response rate 33.4%) were included for analyses. More than half of the AYAs (58.5%) experienced health-related conditions after their cancer diagnosis, of whom 51.4% were diagnosed with two or more conditions. Participants reported conditions related to vision (15.0%), digestive system (15.0%), endocrine system (14.1%), cardiovascular system (11.7%), respiratory system (11.3%), urinary tract system (10.9%), depression (8.6%), hearing (7.4%), arthrosis (6.9%), secondary malignancy (6.4%), speech-, taste and smell (4.5%), and rheumatoid arthritis (2.1%). Time since diagnosis, tumor type, age at diagnosis, and educational level were most frequently associated with a health-related condition.

CONCLUSIONS

A significant proportion of long-term AYA cancer survivors report having one or more health-related conditions.

IMPLICATIONS FOR CANCER SURVIVORS

Future research should focus on better understanding the underlying mechanisms of, and risk factors for, these health-related conditions to support the development and implementation of risk-stratified survivorship care for AYA cancer survivors to further improve their outcomes.

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).

Risk of chronic health conditions in lesbian, gay, and bisexual survivors of adolescent and young adult cancers

BACKGROUND

In the general population, individuals with minoritized sexual orientation and gender identity have a higher burden of chronic health conditions than heterosexual individuals. However, the extent to which sexual orientation is associated with excess burden of chronic conditions in adolescent and young adult cancer survivors (AYACS) is unknown.

METHODS

Lesbian, gay, and bisexual (LGB) AYACSs, LGB individuals without a history of cancer, and heterosexual AYACSs were identified by self-reported data from the cross-sectional National Health Interview Survey (2013-2020). Socioeconomic factors and the prevalence of chronic health conditions were compared between groups using χ2 tests. Logistic regression methods were used to determine the odds of chronic conditions by socioeconomic factors within and between survivor and comparison groups.

RESULTS

One hundred seventy LGB cancer survivors, 1700 LGB individuals without a history of cancer, and 1700 heterosexual cancer survivors were included. Compared with heterosexual survivors, LGB survivors were less likely to be married (p = .001) and more likely to have never been married (p < .001). LGB survivors were more likely to have incomes between 100% and 200% of the federal poverty level than LGB individuals without a history of cancer (p = .012) and heterosexual survivors (p = .021) and were less likely to report incomes >200% the federal poverty level. LGB survivors had higher odds of chronic health conditions than LGB individuals without a history of cancer (odds ratio, 2.45; p < .001) and heterosexual survivors (odds ratio, 2.16; p = .003).

CONCLUSIONS

LGB AYACSs are at increased risk of having chronic health conditions compared with both LGB individuals without a history of cancer and heterosexual AYACSs.

VersKiK qualitative study design: actual follow-up needs of paediatric cancer survivors, their informal caregivers and follow-up stakeholder perceptions in Germany

INTRODUCTION

This article presents the study design of the qualitative part of the VersKiK study (Long-term care, care needs and wellbeing of individuals after cancer in childhood or adolescence: study protocol of a large scale multi-methods non-interventional study) aiming to explore actual follow-up needs of childhood and adolescence cancer survivors and their informal caregivers, gaps in current follow-up care provision and trajectories of cancer survivors' transition from paediatric to adult healthcare.

METHODS AND ANALYSIS

We will conduct up to 30 interviews with survivors of childhood and adolescence cancer and their informal caregivers with up to 20 participant observations of follow-up appointments. The results of these will be discussed in up to four focus groups with healthcare professionals and representatives of self-help groups. The study design aims to evaluate follow-up care after childhood cancer considering perspectives from survivors, their informal caregivers as well as healthcare providers. The combination of different data sources will allow us to get an in-depth understanding of the current state of follow-up care after paediatric cancer in Germany and to suggest recommendations for care improvement.

ETHICS AND DISSEMINATION

The VersKiK study was approved by the Ethics Committee Otto von Guericke University on 2 July 2021 (103/21), by the Ethics Committee of Johannes Gutenberg University Mainz on 16 June 2021 (2021-16035), by the Ethics Committee University of Lübeck on 10 November 2021 (21-451), by the Ethics Committee University of Hospital Bonn on 28 February 2022 (05/22).

A Systematic Review of the Characteristics and Effects of Physical Activity Interventions on Physical Activity Engagement, Long-Term and Late Effects, and Quality of Life in Adolescent and Young Adult Cancer Survivors

Physical activity (PA) may minimize long-term and late effects experienced by cancer survivors. However, the efficacy of PA interventions in increasing PA engagement among adolescent and young adult (AYA) cancer survivors diagnosed between 15 and 39 is not well understood. This systematic review aimed to examine the effects of moderate- to high-intensity or strength training PA interventions on PA engagement in AYA cancer survivors. Secondary aims included describing intervention components unique to efficacious interventions, identifying symptom management in PA interventions, and evaluating intervention effects on quality of life (QoL), and long-term or late effects of cancer. We searched PubMed, CINAHL, PsycINFO, SportDiscus, Cochrane Library, and Scopus databases from inception to August 2022 and identified 12 articles, including 8 randomized controlled trials and 4 quasi-experimental studies. The effect of PA interventions on PA engagement was mixed, with four studies reporting increases in PA engagement ranging from 18.4 to 113.8 min/week postintervention. There was great diversity in PA intervention components. Motivational interviewing, supervised and unsupervised PA sessions together, moderate-intensity PA only, and mindful meditation were components unique to efficacious interventions. No intervention incorporated symptom management components. Studies provided some evidence of PA interventions on potential long-term effects of cancer, with positive impact on fatigue, and some evidence of improved anxiety, sleep, and QoL. Given limited research with AYA cancer survivors, additional research is needed to identify effective intervention components, integrate symptom management strategies into PA interventions, and track effects of PA interventions on late and long-term effects of cancer in this population.

Health Care Access Barriers and Self-Reported Health Among Adolescent and Young Adult Cancer Survivors

Purpose: Adolescents and young adult (AYA) cancer survivors (15-39 years at diagnosis) are at risk for treatment-related late effects but face barriers in accessing survivorship care. We examined the prevalence of five health care access (HCA) barriers: affordability, accessibility, availability, accommodation, and acceptability. Methods: We identified AYA survivors from the University of North Carolina (UNC) Cancer Survivorship Cohort who completed a baseline questionnaire in 2010-2016. Participants had a history of cancer, were ≥18 years of age, and receiving care at a UNC oncology clinic. The sample was restricted to AYA survivors who were interviewed ≥1 year postdiagnosis. We used modified Poisson regression to estimate prevalence ratios (PRs) for the association between HCA barriers and self-reported fair or poor health, adjusted for sociodemographic and cancer characteristics. Results: The sample included 146 AYA survivors who were a median age of 39 at the time of the survey. The majority (71%)-and 92% of non-Hispanic Black survivors-reported at least one HCA barrier, including acceptability (40%), accommodation (38%), or affordability (31%). More than one-quarter of survivors (28%) reported fair or poor health. Affordability barriers (PR: 1.89, 95% confidence interval [CI]: 1.13-3.18) and acceptability barriers (PR: 1.60, 95% CI: 0.96-2.66) were associated with a higher prevalence of fair/poor health, as were the cumulative effects of multiple HCA dimensions reported as barriers. Conclusions: Barriers across multiple HCA dimensions were prevalent and associated with worse health in AYA survivors. Findings highlight the need to better understand and target specific barriers to care for diverse AYA survivors to improve their long-term health.

Long-term second primary cancer risk in adolescent and young adult (15-39 years) cancer survivors: a population-based study in the Netherlands between 1989 and 2018

BACKGROUND

Few studies have comprehensively investigated the long-term second cancer risk among adolescent and young adult (AYA, aged 15-39 years) cancer survivors. This study investigated the long-term second cancer risk by including the full range of first and second cancer combinations with at least 10 observations in the Netherlands between 1989 and 2018.

MATERIALS AND METHODS

First and second primary cancer data of all 6-month AYA cancer survivors were obtained from the nationwide population-based Netherlands Cancer Registry. Excess cancer risk compared to the general population was assessed with standardized incidence ratio (SIR) and absolute excess risk (AER) statistics up to 25 years after diagnosis. Cumulative incidences were estimated, using death as a competing risk factor. Analyses were carried out with and without applying multiple cancer rules.

RESULTS

The cohort included 99 502 AYA cancer survivors. Male survivors had a 2-fold higher risk of developing any cancer compared to the general population, whereas this was around 1.3-fold in females. AERs were 17.5 and 10.1 per 10 000 person-years for males and females. The long-term excess risk of cancer was significantly higher for most first and second primary cancer combinations, but comparable and lower risk estimates were also observed. Application of the multiple cancer rules resulted in a noticeable risk underestimation in melanoma, testicular, and breast cancer survivors. Risk outcomes remained similar in most cases otherwise. The cumulative incidence of second cancer overall increased over time up to 8.9% in males and 10.3% in females at 25 years' follow-up. Highest long-term cumulative incidences were observed among lymphoma survivors (13.3% males and 18.9% females).

CONCLUSIONS

AYA cancer survivors have a higher cancer risk compared to the general population for most cancers up to 25 years after their initial cancer diagnosis. Additional studies that investigate risk factors for the specific cancer type combinations are needed to develop personalized follow-up strategies.

Financial burdens during the COVID-19 pandemic are related to disrupted healthcare utilization among survivors of adolescent and young adult cancers

PURPOSE

We examined whether financial burdens occurring during the COVID-19 pandemic impacted healthcare utilization among survivors of adolescent and young adult cancers.

METHODS

We surveyed survivors enrolled in a patient navigation program to obtain self-reports of delayed/skipped cancer care or other care, changes to medication obtainment, and changes to medication use since the COVID-19 pandemic began. Reported financial burdens were defined as financial toxicity in the past 4 weeks (COmprehensive Score for financial Toxicity [COST] ≤ median 21) and material hardships (range = 4-11) since March 2020. Adjusted logistic regression models calculated associations and effect modification by gender.

RESULTS

Survivors (n = 341) were mostly female (61.3%) and non-Hispanic White (83.3%). Nearly 20% delayed/skipped cancer care, 35.2% delayed/skipped other care, 19.1% changed medication obtainment, and 12.6% changed medication use. Greater material hardships were associated with delayed/skipped cancer care (odds ratio (OR) = 3.13, 95% CI = 1.44-6.81) and other care (OR = 2.17, 95% CI = 1.18-3.98), and changed medication obtainment (OR = 2.72, 95% CI = 1.43-5.18) or use (OR = 4.49, 95% CI = 2.05-9.80). Financial toxicity was associated with delayed/skipped other care (OR = 2.53, 95% CI = 1.31-4.89) and changed medication obtainment (OR = 1.96, 95% CI = 1.01-3.83) and medication use (OR = 3.73, 95% CI = 1.59-8.73). The association of material hardships and any changes in healthcare utilization was greater among female compared to male survivors.

CONCLUSION

Financial burdens experienced during the pandemic impeded survivors' ability to utilize necessary healthcare, with worse impacts among female survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Delayed or skipped healthcare may lead to an increased cancer mortality or severity of therapy-related conditions. Providing resources that enable survivors experiencing financial burdens to continue critical cancer and preventive care during the COVID-19 pandemic is a priority.

VersKiK: Study protocol of an observational registry-based study on the current state of follow-up care and adherence to follow-up guidelines after cancer in childhood or adolescence

BACKGROUND

This article describes the study design of the quantitative part of the VersKiK study, The primary objectives of this study are to examine the occurrence of late effects in survivors of childhood or adolescent cancer (module 1), investigate health-related vulnerabilities and medical service utilization within this survivor group (modules 1 and 3), and assess the alignment between documented follow-up care for cardiological and audiological late effects with guideline recommendations, along with evaluating the extent of adherence among paediatric cancer survivors (module 3).

METHODS

This is a non-interventional retrospective observational cohort study. It is based on stochastically linked insurance claims data from approximately 150,000 statutory insured persons with information concerning around 25,000-30,000 cancer survivors recorded in the German Childhood Cancer Register (GCCR). To explore adherence to selected follow-up guidelines, intention to treat treatment data from clinical study groups for particular diagnostic entities will be additionally included.

DISCUSSION

The growing group of survivors after cancer in childhood and adolescence is representing a special population with an increasing demand for life-long healthcare services through relative high probability of late effects. Currently, there is a limited evidence in Germany on utilization of corresponding medical services and adherence to follow-up guidelines. With this study design, we are aiming to address these gaps and, consequently, suggest improvements to existing follow-up guidelines and follow-up care provision in Germany.

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.

A randomized controlled pilot study assessing feasibility and safety of a wilderness program for childhood, adolescent, and young adult cancer survivors: the WAYA study

BACKGROUND

The majority of childhood, Adolescent and Young Adult (AYA) cancer survivors suffers from long-lasting health issues following cancer treatment. It is therefore critical to explore effective health promotion strategies to address their needs. Exposure to nature is a promising approach to support the needs of young cancer survivors. This study investigated whether it is feasible to conduct a randomized controlled trial (RCT) of a wilderness program for childhood and AYA cancer survivors.

METHODS

Eligible participants were aged 16-39 years, had a cancer diagnosis, and met minimal criteria. Seventy-one individuals expressed interest and 59 were randomized to either a wilderness or a holiday program. The wilderness program involved an 8-day expedition including backpacking, sea kayaking, gorge climbing, camping, bush-craft skills, and mindfulness-practices. It was followed by a 4-day basecamp after 3 months. The comparison was an 8-day holiday program at a Spa-hotel followed by a 4-day holiday program at the same hotel after 3 months. Primary outcome was study feasibility and safety.

RESULTS

Ultimately, 19 AYAs participated in the wilderness and 23 in the holiday program. All completed the study at one-year follow-up. Participants were mostly female (70%) and represented diverse cancers. Clinical characteristics were similar between study arms excepting greater age at cancer diagnosis in the wilderness program (age 19.1 vs. 12.5; p = 0.024). Program adherence and data completeness was high (> 90%) in both arms. Adverse Effects (AEs) in the wilderness vs. the holiday program were similar (Relative Risk: 1.0, 95% Confidence Interval 0.8-1.3). The most frequent AE was tiredness, all were mild to moderate in severity, and serious AEs were not reported. Nature connectedness significantly increased over time in the wilderness program participants, but not in the holiday program (p < 0.001). No differences were found between the two study arms regarding quality of life, self-esteem, or self-efficacy.

CONCLUSION

It is feasible to conduct a RCT and a supervised wilderness adventure is equally safe for childhood and AYA cancer survivors as a holiday program. This pilot study lays the foundation for a larger RCT to investigate the effectiveness of wilderness programs on the health of young cancer survivors.

Social Support, Coping, and Cancer-Related Health Burden in Long-term Survivors Treated with Hematopoietic Stem Cell Transplantation as Adolescents or Young Adults

Purpose: Long-term adolescent and young adult hematopoietic stem cell transplantation (HCT) survivors face complex physical and psychological treatment effects that contribute to cancer-related health burden. We aimed to identify the role of social support and coping strategies on cancer-related health burden. Methods: This cross-sectional analysis included HCT recipients from the INSPIRE trial [NCT00799461], who received their first transplant between ages 15 and 39. As our primary outcome, we used the health burden subscale of the Cancer and Treatment Distress measure. We assessed correlates using the Short Form-36v2 physical component summary, brief Coping Orientation to Problems Experienced (COPE), and ENRICHD Social Support Inventory. We used hierarchical multivariable linear regression to identify factors associated with cancer-related health burden, with the first step including sociodemographic and clinical factors, the second step adding physical function, and the third step including social support and coping. Results: Participants (N = 293) were 52% male and 93% white, non-Hispanic, with a mean age of 30.2 (standard deviation 6.6) at first transplant. In step one, sex accounted for ∼3% of the variance (p = 0.006). Adding physical function explained an additional 33% of the variance (p = <0.001). Social support and coping strategies explained 11% of the variance (p = <0.001). The final model explained 47% of the variance; better physical function, more social support, and active coping were associated with lower cancer-related health burden, while female sex, venting, and distraction were associated with higher cancer-related health burden. Conclusion: Supporting physical function and fostering social support and active coping may help mitigate cancer-related health burden in this population. Clinical Trial Registration: NCT00799461.

Breast cancer after thoracic radiotherapy in young patients: what does the radiologist need to know?

Radiation-induced secondary tumors constitute a rare complication of radiation therapy and typically occur in or near the irradiated area. Women who undergo thoracic radiotherapy before 30 years of age have a significantly greater lifetime risk of developing breast cancer than do those in the general population. It is recommended that a patient who has previously received thoracic radiotherapy with a radiation dose ≥ 10 Gy subsequently undergo annual screening with mammography and magnetic resonance imaging, beginning eight years after the initial treatment or when the patient has reached 25 years of age (whichever comes later). The treatment of secondary breast cancer in this population should be individualized and should be discussed with a multidisciplinary team to avoid toxicity related to the treatment of the primary cancer.

Provision and delivery of survivorship care for adult patients with haematological malignancies: A scoping review protocol

INTRODUCTION

Haematological malignancies are a heterogenous group of blood and lymphatic cancers. Survivorship care is a similarly diverse term concerning patients' health and wellbeing from diagnosis to end of life. Survivorship care for patients with haematological malignancies has traditionally been consultant-led and secondary care-based, although shifts away from this model have been occurring, largely via nurse-led clinics and interventions with some remote monitoring. However, there remains a lack of evidence regarding which model is most appropriate. Although previous reviews exist, patient populations, methodologies, and conclusions are varied, and further high-quality research and evaluation has been recommended.

AIMS

The aim of the scoping review this protocol describes is to summarise current evidence on the provision and delivery of survivorship care for adult patients diagnosed with a haematological malignancy, and to identify existing gaps to inform future research.

METHODOLOGY

A scoping review will be carried out utilising Arksey and O'Malley's guidelines as its methodological framework. Studies published in the English language from December 2007 to the present will be searched on bibliographic databases, including Medline, CINAHL, PsycInfo, Web of Science, and Scopus. Papers' titles, abstracts, and full text will predominantly be screened by one reviewer with a second reviewer blind screening a proportion. Data will be extracted using a customised table developed in collaboration with the review team, and presented in tabular and narrative format, arranged thematically. Studies included will contain data regarding adult (25+) patients diagnosed with any haematological malignancy in combination with aspects related to survivorship care. The survivorship care elements could be delivered by any provider within any setting, but should be delivered pre- or post-treatment, or to patients on a watchful waiting pathway.

REGISTRATION

The scoping review protocol has been registered on the Open Science Framework (OSF) repository Registries (https://osf.io/rtfvq; DOI: 10.17605/OSF.IO/RTFVQ).

Financial toxicity among adolescent and young adult cancer survivors: A systematic review of educational attainment, employment, and income

PURPOSE

To identify, evaluate and summarize the evidence on educational attainment, employment status and income of AYAs surviving cancer.

METHODS

A search of six databases for articles published between 01/01/2010 and 03/31/2022 was performed. Articles with an AYA survivorship population, quantitative design and a cancer-free comparator group were included. Data extraction was conducted, and quality appraisal was completed using ROBINS-I. Results were summarized using a narrative synthesis.

RESULTS

A total of 2801 articles were identified, of which 12 were included. Among the limited evidence, educational attainment did not differ from cancer-free peers. Survivors were more likely to be unemployed, have lower incomes and require social security for income supplementation. Evidence suggested that females, diagnosis of brain cancer and the presence of late-effects were among the risk factors for severe outcomes.

CONCLUSIONS

Limited socioeconomic evidence exists for AYAs surviving cancer. Long-lasting financial toxicities occur and highlights a need for further investigation.

Adolescent and young adult cancers: unmet needs and closing the gaps

PURPOSE OF REVIEW

There is a growing population of adolescent and young adult (AYA, ages 15-39 years) cancer patients and survivors, and the field of AYA oncology is rapidly evolving. Despite an increased focus on survival and quality of life for AYAs, gaps in knowledge remain. The current review focuses on what is known across several domains unique to AYA cancer care as well as areas of improvement and future directions in research and intervention.

RECENT FINDINGS

Due to the developmental stages included in the AYA age range, a cancer diagnosis and treatment can affect relationships, education and employment, finances, and long-term health differently than diagnoses in younger or older populations. Recent studies that have focused on these unique aspects of AYA cancer care, including health-related quality of life (HRQoL), fertility, financial toxicity, barriers to clinical trial enrollment, genetic predisposition, and survivorship care are included in the current review.

SUMMARY

Although studies have described many of the challenges faced by AYAs across the cancer continuum from diagnosis to survivorship, more work is needed, particularly in systematically measuring HRQoL, eliminating barriers to clinical trial enrollment, addressing financial toxicity, and increasing access to fertility preservation and high-quality survivorship care.

The Transformation of Adolescent and Young Adult Oncological and Supportive Care in Canada: A Mixed Methods Study

Background: Due to ongoing disparity in the specialized care available to adolescents and young adults (AYAs) with cancer, this study aimed to understand the gaps and barriers to accessing care and preferences on types of solutions at a national Canadian level. Methods: A mixed-methods study involving an online survey and focus groups (FGs) was conducted among AYAs residing in different regions of Canada. Results: There were a total of 174 survey respondents, of whom the majority were between 30–39 years of age (n = 125, 71.8%). Of the 174 respondents, 36 (20.7%) participated in one of seven FGs. Triangulation of the results illustrated that AYAs are not appropriately informed about the long-term health risks of being treated for cancer and where/how to seek support. These results culminated into three themes: (1) the need for AYA relevant and timely information about health risks; by (a) producing health risk-related content with the AYA life stage in mind; (b) providing a guided “map” to help AYAs anticipate what they may experience, and (c) providing checklists to help AYAs navigate their experience; (2) need for tailored and timely supportive care including (a) establishing ongoing check-ins and (b) receiving navigation support, and (3) need for enhanced connections by creating (a) a space to gather, connect and seek mentorship and (b) a hub to access information. Conclusion: AYAs continue to lack sufficient support both during and following cancer and mechanisms are required to ensure longitudinal support is provided across jurisdictions and in all stages of the cancer journey.

pH-Responsive Polymer Nanomaterials for Tumor Therapy

The complexity of the tumor microenvironment presents significant challenges to cancer therapy, while providing opportunities for targeted drug delivery. Using characteristic signals of the tumor microenvironment, various stimuli-responsive drug delivery systems can be constructed for targeted drug delivery to tumor sites. Among these, the pH is frequently utilized, owing to the pH of the tumor microenvironment being lower than that of blood and healthy tissues. pH-responsive polymer carriers can improve the efficiency of drug delivery in vivo, allow targeted drug delivery, and reduce adverse drug reactions, enabling multifunctional and personalized treatment. pH-responsive polymers have gained increasing interest due to their advantageous properties and potential for applicability in tumor therapy. In this review, recent advances in, and common applications of, pH-responsive polymer nanomaterials for drug delivery in cancer therapy are summarized, with a focus on the different types of pH-responsive polymers. Moreover, the challenges and future applications in this field are prospected.

Psychosocial and Biological Outcomes of Immersive, Mindfulness-Based Treks in Nature for Groups of Young Adults and Caregivers Affected by Cancer: Results from a Single Arm Program Evaluation from 2016-2021

The COVID-19 pandemic has left many individuals suffering from “connection deficit disorder” given changes to the way we work, go to school, socialize, and engage in daily activities. Young adults affected by cancer between the ages of 18–39 have known this connection deficit long before the pandemic. Being diagnosed and treated for cancer during this time can significantly disrupt engagement in important educational, career, social, and reproductive pursuits, and contribute to increased stress, anxiety, depression, and other negative outcomes. Experiencing meaningful connection—with nature, with peers who understand, and with oneself, may help assuage this adverse effect of disconnect. A single arm within-subjects program evaluation was conducted to examine outcomes following participation in immersive, multi-night, mindfulness-based treks in nature in a sample of young adults (n = 157) and caregivers (n = 50) affected by cancer from 2016–2021. Pre to post-trek changes included significant (p < 0.001) self-reported improvements in feeling connected to nature (d = 0.93–0.95), peers (d = 1.1–1.3), and oneself (d = 0.57–1.5); significant (p < 0.001) improvements on PROMIS Anxiety (d = 0.62–0.78), Depression (d = 0.87–0.89), and Sleep Disturbance (d = 0.37–0.48) short forms; and significant (p < 0.05) changes in pro-inflammatory biomarkers (d = 0.55–0.82). Connection-promoting experiences like this have the potential to improve health and wellbeing in this population and serve as a model for others.
