A comparison of two models of follow-up care for adult survivors of childhood cancer

The integration of primary care and childhood cancer survivorship care: a scoping review

PURPOSE

This scoping review describes existing care models that integrate primary care and childhood cancer survivorship care, examines the effectiveness of these models, and characterizes barriers and facilitators to their integration.

METHODS

A systematic search (PubMed®, CINAHL®, Embase®) was conducted to identify citations which were evaluated against inclusion criteria using the PICOTTS framework. The PRISMA-ScR extension for scoping reviews was used to report review findings (protocol https://osf.io/92xbg ).

RESULTS

Twenty-three studies were included. Three care models integrating primary care and childhood cancer survivorship care were identified: consultative shared care in a primary care setting (N = 3); longitudinal shared care (N = 2); and PCP-led care employing a survivorship care plan (N = 5). While many described risk-adapted care, few used risk stratification approaches to inform care. Measures of model effectiveness varied, with discrepant findings regarding late effects detection in PCP-led approaches. The most frequently cited barriers and facilitators reflected provider- and system-level factors (PCP knowledge/experience identified as greatest barrier (N = 11); clinical information from oncologist identified as greatest facilitator (N = 9)).

CONCLUSIONS

Identified models depended on PCP knowledge and healthcare system coordination, and studies suggested the need for strong oncologic involvement in follow-up care. Improved training for PCPs and the coordinated transfer of clinical information could facilitate their involvement in such care. Overall, standardized measures of effectiveness are needed to deliver optimal childhood cancer survivorship care.

IMPLICATIONS FOR CANCER SURVIVORS

The literature revealed three care models defined by SCP use, provider involvement, and continuity of care, with several studies recommending oncologic involvement in follow-up care for high-risk survivors.

Parent caregivers' preferences and satisfaction with currently provided childhood cancer survivorship care

PURPOSE

The aim of this study was to investigate the level of satisfaction of parent caregivers of childhood cancer survivors (CCSs) with currently provided survivorship care and their preferences for survivorship care provider.

METHODS

Study subjects were parent caregivers recruited at three hospitals in Korea. Study data were collected from self-administered questionnaires and medical records. We assessed parent caregivers' levels of satisfaction with specific survivorship care contents and preferred types of survivorship care provider among oncologists, primary care physicians (PCPs), and institutional general physicians (IGPs). Factors associated with parent caregivers' preferences for survivorship care provider were evaluated by multiple logistic regression analysis.

RESULTS

680 parent caregivers (mother 62.1% and father 37.9%) of 487 CCSs (mean age at diagnosis: 6.9 ± 5.1 years; mean time since treatment completion 5.4 ± 4.4 years) were included. Parent caregivers' dissatisfaction was the highest with screening for second primary cancer, followed by psychosocial problem management. Higher educational level of parent caregiver, parent caregiver's higher level of dissatisfaction with currently provided care, higher age of CCSs at cancer diagnosis, history of receiving hematopoietic stem cell transplant, and longer time lapse after cancer treatment were significantly associated with parent caregivers' higher preference for PCPs or IGPs than oncologists. Parent caregiver's multiple comorbidities and higher fear of cancer recurrence were associated with parent caregivers' higher preference for oncologists than PCPs or IGPs. Around 80% of parent caregivers recognized that a shared care system was helpful for promoting the health of CCSs.

CONCLUSION

Parent caregivers were substantially dissatisfied with currently provided care, especially regarding the health issues not directly associated with the primary cancer. Parent caregivers' preferences for survivorship care provider is influenced by multiple factors, including age and survival time of CCSs, characteristics of parent caregivers, satisfaction level with care, and specific survivorship care contents.

IMPLICATIONS FOR CANCER SURVIVORS

The findings of our study suggest that shared survivorship care for CCSs with consideration of specific care contents can complement the current oncologist-led survivorship care system.

Alberta Childhood Cancer Survivorship Research Program

Adverse outcomes after childhood cancer have been assessed in a range of settings, but most existing studies are historical and ascertain outcomes only after 5-year survival. Here, we describe the Alberta Childhood Cancer Survivorship Research Program and its foundational retrospective, population-based cohort of Albertan residents diagnosed with a first primary neoplasm between the ages of 0 and 17 years from 1 January 2001 to 31 December 2018. The cohort was established in collaboration with the Alberta Cancer Registry and Cancer in Young People in Canada program and has been linked to existing administrative health databases and patient-reported outcome questionnaires. The cohort comprised 2580 survivors of childhood cancer, 1379 (53.4%) of whom were 5-year survivors. Approximately 48% of the cohort was female, 47% of the cohort was diagnosed between 0 and 4 years of age, and the most frequent diagnoses were leukemias (25.4%), central nervous system tumors (24.0%), and lymphomas (14.9%). Detailed treatment information was available for 1741 survivors (67.5%), with manual abstraction ongoing for those with missing data. By the study exit date, the median time since diagnosis was 5.5 years overall and 10.4 years for 5-year survivors. During the follow-up time, 82 subsequent primary cancers were diagnosed, 20,355 inpatient and 555,425 ambulatory/outpatient events occurred, 606,773 claims were reported, and 437 survivors died. The results from this research program seek to inform and improve clinical care and reduce cancer-related sequelae via tertiary prevention strategies.

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

BACKGROUND

Adolescent and young adult (AYA) cancer survivors face physical and psychological sequelae related to having cancer decades after treatment completion. It is unclear if AYA cancer survivors are at increased risk for late psychiatric disorders.

METHODS

We used the Alberta AYA Cancer Survivor Study that includes 5-year survivors of cancer diagnosed at age 15-39 years during 1991 to 2013. The primary outcome was incidence of psychiatric disorder (composite outcome) including anxiety, depressive, trauma- and stressor-related, psychotic, and substance use disorders that were identified using coding algorithms for administrative health databases. A validated coding algorithm identified people who experienced a suicide attempt or event of self-harm. Secondary outcomes were incidences of diagnoses by type of psychiatric disorder.

RESULTS

Among 12 116 AYA 5-year cancer survivors (n = 4634 [38%] males; n = 7482 [62%] females), 7426 (61%; n = 2406 [32%] males; n = 5020 [68%] females) were diagnosed with at least 1 of 5 psychiatric disorders occurring at least 3 years after cancer diagnosis. Survivors of all cancer types were most often diagnosed with anxiety (males: 39.0%, 95% confidence interval [CI] = 37.6% to 40.4%; females: 54.5%, 95% CI = 53.3% to 55.6%), depressive (males: 32.7%, 95% CI = 31.3% to 34.0%; females: 47.0%, 95% CI = 45.8% to 48.1%), and trauma- and stressor-related disorders (males: 13.5%, 95% CI =12.5% to 14.5%; females: 22.5%, 95% CI = 21.6% to 23.5%).

CONCLUSIONS

Anxiety, depressive, and trauma- and stressor-related disorders are common among 5-year survivors of AYA cancer. Primary, secondary, or tertiary preventive strategies for AYAs diagnosed with cancer, particularly at an early age, are needed to mitigate risk of potentially severe outcomes because of psychiatric disorders.

Development and Validation of Models to Predict Poor Health-Related Quality of Life Among Adult Survivors of Childhood Cancer

IMPORTANCE

Risk prediction models are important to identify survivors of childhood cancer who are at risk of experiencing poor health-related quality of life (HRQOL) as they age.

OBJECTIVE

To develop and validate prediction models for a decline in HRQOL among adult survivors of childhood cancer.

DESIGNS, SETTING, AND PARTICIPANTS

This prognostic study included 4755 adults from the Childhood Cancer Survivor Study (CCSS) diagnosed between January 5, 1970, and December 31, 1986, who completed baseline (time 0 [November 3, 1992, to August 28, 2003]) and 2 follow-up (time 1 [February 12, 2002, to May 21, 2005] and time 2 [January 6, 2014, to November 30, 2016]) surveys. Data were analyzed from June 19, 2019, to February 2, 2022.

EXPOSURES

Sociodemographic, lifestyle, and emotional factors, and chronic health conditions (CHCs) were assessed at time 0 and time 1, and neurocognitive factors were assessed at time 1 to predict HRQOL at time 2 and a decline in HRQOL between time 1 and time 2. Impaired health states were defined as CHC grades 2 to 4 using the modified Common Terminology Criteria for Adverse Events, version 4.03, and mental and neurocognitive status as 1 SD or more below reference levels.

MAIN OUTCOMES AND MEASURES

Health-related quality of life was operationalized using the Medical Outcomes Study 36-Item Short Form Health Survey Physical (PCS) and Mental (MCS) Component Summary and classified by optimal (≥40) or suboptimal (<40) at each point (main outcome). A decline in HRQOL was defined as a change from optimal to suboptimal between time 1 and time 2. Multivariable logistic regression identified factors associated with HRQOL decline. The cohort was randomly split into training (80%) and test (20%) data sets for model development and validation; the area under the receiver operating characteristic curve was used to evaluate prediction performance.

RESULTS

A total of 4755 adults (mean [SD] age at time 0, 24.3 [7.6] years; 2623 [55.2%] women) were included in the analysis. Between time 1 and time 2, 285 of 3294 survivors (8.7%) had declining PCS and 278 of 3294 (8.4%) had declining MCS. Risk factors associated with PCS decline included female sex (odds ratio [OR], 1.67 [95% CI, 1.25-2.24]), family income less than $20 000 vs $80 000 or more (OR, 2.00 [95% CI, 1.21-3.30]), presence of CHCs (OR for neurological, 2.16 [95% CI, 1.51-3.10]; OR for endocrine, 2.25 [95% CI, 1.44-3.52]; OR for gastrointestinal tract, 1.89 [95% CI, 1.32-2.69]; OR for respiratory, 1.66 [95% CI, 1.06-2.59]; OR for cardiovascular, 1.53 [95% CI, 1.14-2.06]), and depression (OR, 1.79 [95% CI, 1.20-2.67]). Risk factors associated with MCS decline included unemployment vs full-time employment (OR, 1.68; [95% CI, 1.19-2.38]), current vs never cigarette smoking (OR, 2.03 [95% CI, 1.37-3.00]), depression (OR, 4.29 [95% CI, 2.44-7.55]), somatization (OR, 1.63 [95% CI, 1.05-2.53]), impaired task efficiency (OR, 1.90 [95% CI, 1.34-2.68]), and impaired organization (OR, 1.67 [95% CI, 1.12-2.48]). The areas under the receiver operating characteristic curve for the test models were 0.74 (95% CI, 0.67-0.81) for declining PCS and 0.68 (95% CI, 0.60-0.75) for declining MCS.

CONCLUSIONS AND RELEVANCE

In this prognostic study of adult survivors of childhood cancer who experienced declining HRQOL, CHCs were associated with a decline in physical HRQOL, whereas current smoking and emotional and neurocognitive impairment were associated with a decline in mental HRQOL. These findings suggest that interventions targeting modifiable risk factors are needed to prevent poor HRQOL in this population.

Interventions to address disparities and barriers to pediatric cancer survivorship care: a scoping review

PURPOSE

Many childhood cancer survivors experience disparities due to barriers to recommended survivorship care. With an aim to demonstrate evidence-based approaches to alleviate barriers and decrease disparities, we conducted a scoping review of (1) proposed strategies and (2) evaluated interventions for improving pediatric cancer survivorship care.

METHODS

We searched research databases (PubMed, CINAHL, and PsycINFO), research registries, and grey literature (websites of professional organizations and guideline clearing houses) for guidelines and published studies available through October 2020 (scoping review registration: https://doi.org/10.17605/OSF.IO/D8Q7Y ).

RESULTS

We identified 16 proposed strategies to address disparities and barriers endorsed by professional organizations including clinical practice guidelines (N=9), policy statements (N=4), and recommendations (N=3). Twenty-seven published studies evaluated an intervention to alleviate disparities or barriers to survivorship care; however, these evaluated interventions were not well aligned with the proposed strategies endorsed by professional organizations. Most commonly, interventions evaluated survivorship care plans (N=11) or models of care (N=11) followed by individual survivorship care services (N=9). Interventions predominantly targeted patients rather than providers or systems and used technology, education, shared care, collaboration, and location-based interventions.

CONCLUSIONS

Published studies aimed at overcoming disparities and barriers to survivorship care for childhood cancer survivors revealed that gaps remain between published recommendations and empirical evaluations of interventions aiming to reduce barriers and disparities.

IMPLICATIONS FOR CANCER SURVIVORS

Additional research is needed to identify evidence-based interventions to improve survivorship care for childhood cancer survivors.

Quality of life among survivors of adolescent and young adult cancer in Canada: A Young Adults With Cancer in Their Prime (YACPRIME) study

BACKGROUND

The quality of life (QoL) among survivors of adolescent and young adult (AYA) cancer may be compromised compared with that in the general population. In this study, the authors: 1) assessed for differences in QoL among a national study of AYA cancer survivors compared with the Canadian population and 2) explored the factors associated with poorer QoL in AYA cancer survivors.

METHODS

For the current research, data from the Young Adults With Cancer in Their Prime study were used. QoL was measured using physical and mental component scores from a 12-item short-form health status measure. A comparison group was derived from the Canadian Community Health Survey.

RESULTS

AYAs (n = 195; 17.8% male; mean ± SD: 35.62 ± 6.89 years on study, 6.48 ± 5.73 years from treatment) were compared with a comparison sample (n = 665; 21.2% male). Among survivors, 31.8% reported poor physical health, and 49.7% reported poor mental health. Compared with the general population, AYAs had significantly lower physical health (F[1,818] = 52.80; P = .00) and mental health (F[1,818] = 83.54; P = .00), controlling for sex and age. Multivariable logistic regression analyses revealed that an annual income level <$40,000 (adjusted odds ratio [AOR], 8.32; 95% CI, 2.85-24.30), poor sleep quality (AOR, 1.19; 95% CI, 1.06-1.33), worse body image (AOR, 1.08; 95% CI, 1.02-1.14), and higher social support (AOR, 1.02; 95% CI, 1.00-1.05) were significantly associated with poor physical health. Poor sleep quality (AOR, 1.22; 95% CI, 1.08-1.38), body image (AOR, 1.06; 95% CI, 1.01-1.12), fear of cancer recurrence (AOR, 1.13; 95% CI, 1.06-1.21) were associated with poor mental health.

CONCLUSIONS

The QoL of AYAs requires urgent attention. Sleep, body image, and social support may be important modifiable targets for intervention to improve their QoL.

Adherence to cardiomyopathy screening guidelines among adolescent and young adult cancer survivors exposed to chest radiation and/or anthracyclines

PURPOSE

Cancer survivors are at risk for late effects from therapeutic exposures, including cardiovascular complications. To improve outcomes among adolescents and young adults (AYA) with cancer, the National Comprehensive Cancer Network (NCCN) released guidelines for screening services (based on the Children's Oncology Group Long-Term Follow-Up [LTFU] guidelines) for survivors of AYA cancer. To better understand survivorship care gaps, we conducted a baseline evaluation of cardiomyopathy screening among survivors of AYA cancers.

METHODS

Members of Kaiser Permanente Southern California diagnosed with cancer between ages 15 and 39 from 2000 to 2010 with at least 5-year survival after diagnosis who were exposed to chest radiation and/or anthracyclines were included. We calculated the Prevention Index ([PI], proportion of person-time covered by receipt of preventive services relative to the total person-time eligible) to evaluate adherence to recommended cardiomyopathy screenings based on the LTFU through 2016. Predictors for screening were evaluated in multivariable logistic regression.

RESULTS

Among 479 survivors recommended for cardiomyopathy screening, 28 received at least one screening, and the mean PI was 2.38% (SD = 13.05%, median = 0.00%). Compared to stage I, survivors of stage II (odds ratio [OR] = 5.56 [1.05-29.46]) and stage III/IV cancer (OR = 6.08 [1.10-33.54]) were more likely to receive cardiomyopathy screening.

CONCLUSIONS

Cardiomyopathy screening among survivors was low around the time when NCCN AYA oncology guidelines were released.

IMPLICATIONS FOR CANCER SURVIVORS

Our study highlights significant room for improvement for adherence to cardiomyopathy screening recommendations among survivors of AYA cancer. Attention is needed to ensure that recommended cardiomyopathy screenings are met for better management of cardiomyopathy late effects.
