Long-term follow-up of pediatric cancer survivors: education, surveillance, and screening

Neuroblastoma survivors' self-reported late effects, quality of life, health-care use, and risk perceptions

BACKGROUND

Survivors of childhood neuroblastoma are at risk of multiple treatment-related health problems (late effects), impacting their quality of life. While late effects and quality of life among Australia and New Zealand (ANZ) childhood cancer survivors have been reported, the outcomes of neuroblastoma survivors specifically have not been reported, limiting critical information to inform treatment and care.

METHODS

Young neuroblastoma survivors or their parents (as proxy for survivors <16 years) were invited to complete a survey and optional telephone interview. Survivors' late effects, risk perceptions, health-care use, and health-related quality of life were surveyed and analyzed using descriptive statistics and linear regression analyses. In-depth interviews explored participants' experiences, knowledge, and perception of late effects and information needs. Thematic content analysis was used to summarize the data.

RESULTS

Thirty-nine neuroblastoma survivors or parents completed questionnaires (median age = 16 years, 39% male), with 13 also completing interviews. Thirty-two participants (82%) reported experiencing at least 1 late effect, most commonly dental problems (56%), vision/hearing problems (47%), and fatigue (44%). Participants reported high overall quality of life (index = 0.9, range = 0.2-1.0); however, more participants experienced anxiety/depression compared to the population norm (50% met criteria versus 25%, χ2 = 13, p < 0.001). Approximately half of participants (53%) believed they were at risk of developing further late effects. Qualitatively, participants reported knowledge gaps in understanding their risk of developing late effects.

CONCLUSION

Many neuroblastoma survivors appear to experience late effects, anxiety/depression and have unmet cancer-related information needs. This study highlights important areas for intervention to reduce the impact of neuroblastoma and its treatment in childhood and young adulthood.

Recurrence Patterns and Surveillance Imaging in Pediatric Brain Tumor Survivors

Surveillance magnetic resonance imaging (MRI) is routinely used to detect recurrence in pediatric central nervous system (CNS) tumors. The frequency of neuroimaging surveillance varies without a standardized approach. A single-institutional retrospective cohort study evaluated the frequency of recurrences. This study included 476 patients with the majority diagnosed with low-grade glioma (LGG) (n=138, 29%), high-grade glioma (HGG) (n=77, 16%), ependymoma (n=70, 15%), or medulloblastoma (n=61, 13%). LGG, HGG, and ependymoma patients more commonly had multiply recurrent disease ( P =0.08), with ependymoma patients demonstrating ≥2 relapses in 47% of cases. Recurrent disease was identified by imaging more often than clinical symptoms (65% vs. 32%; P =<0.01). Patients diagnosed with meningioma demonstrated the longest mean time to first relapse (74.7 mo) whereas those with atypical teratoid rhabdoid tumor and choroid plexus carcinoma tended to have the shortest time to relapse (8.9 and 9 mo, respectively). Overall, 22 patients sustained first relapse >10 years from initial diagnosis. With a higher tendency toward detection of tumor recurrence/progression on MRI surveillance in comparison to clinical progression, surveillance imaging is necessary in routine follow up of pediatric CNS tumor survivors. With some relapses >10 years from initial diagnosis, imaging beyond this time point may be useful in particular tumor types. While the study is limited in outcome analysis, earlier detection of recurrence would lead to earlier initiation of treatment and implementation of salvage treatment regimens which can impact survival and quality of life.

Health Care Transitions Among Adolescents and Young Adults With Cancer

Survivors of adolescent and young adult (AYA) cancers, defined as individuals diagnosed with a primary malignancy between age 15 and 39 years, are a growing population with unique developmental, psychosocial, and health-related needs. These individuals are at excess risk of developing a wide range of chronic comorbidities compared with the general population and, therefore, require lifelong, risk-based, survivorship care to optimize long-term health outcomes. The health care needs of survivors of AYA cancers are particularly complicated given the often heterogeneous and sometimes fragmented care they receive throughout the cancer care continuum. For example, AYA survivors are often treated in disparate settings (pediatric v adult) on dissimilar protocols that include different recommendations for longitudinal follow-up. Specialized tools and techniques are needed to ensure that AYA survivors move seamlessly from acute cancer care to survivorship care and, in many cases, from pediatric to adult clinics while still remaining engaged in long-term follow-up. Systematic, age-appropriate transitional practices involving well-established clinical models of care, survivorship care plans, and survivorship guidelines are needed to facilitate effective transitions between providers. Future studies are necessary to enhance and optimize the clinical effectiveness of transition processes in AYA cancer survivors.

"It just never ends": Childhood cancer survivors' perceived psychosocial impacts of recurrence and second cancer

OBJECTIVES

Childhood cancer survivors are at risk of developing primary recurrences and new second cancers. Experiencing a recurrence and/or second cancer can be highly distressing for survivors and families. We aimed to understand the psychological impacts of experiencing a recurrence or second cancer and how this potentially influences survivors' engagement with survivorship care.

METHODS

We invited childhood cancer survivors or their parents if survivors were ≤16 years of age from 11 tertiary pediatric oncology hospitals across Australia and New Zealand to complete interviews. We conducted a thematic analysis facilitated by NVivo12.

RESULTS

We interviewed 21 participants of whom 16 had experienced a recurrence, 3 had a second cancer, and 2 had both a recurrence and second cancer. Participants reported that a recurrence/second cancer was a stressful sudden disruption to life, accompanied by strong feelings of uncertainty. Participants tended to be less aware of their second cancer risk than recurrence risk. Some participants reported feelings of anxiousness and despair, describing varying responses such as gratitude or avoidance. Participants shared that the fear of cancer recurrence either motivated them to adopt protective health behaviors or to avoid information and disengage from survivorship care.

SIGNIFICANCE OF RESULTS

Some survivors and their parents have a poor understanding and expressed reluctance to receive information about their risk of second cancer and other treatment-related late effects. Improving the delivery of information about late effects to families may improve their engagement with survivorship care and surveillance, although care must be taken to balance information provision and survivors' anxieties about their future health.

Pediatric central nervous system tumor survivor and caregiver experiences with multidisciplinary telehealth

PURPOSE

Telehealth use to facilitate cancer survivorship care is accelerating; however, patient satisfaction and barriers to facilitation have not been studied amongst pediatric central nervous system (CNS) tumor survivors. We assessed the telehealth experiences of survivors and caregivers in the Pediatric Neuro-Oncology Outcomes Clinic at Dana-Farber/ Boston Children's Hospital.

METHODS

Cross-sectional study of completed surveys among patients and caregivers with ≥ 1 telehealth multidisciplinary survivorship appointment from January 2021 through March 2022.

RESULTS

Thirty-three adult survivors and 41 caregivers participated. The majority agreed or strongly agreed that telehealth visits started on time [65/67 (97%)], scheduling was convenient [59/61 (97%)], clinician's explanations were easy-to-understand [59/61 (97%)], listened carefully/addressed concerns [56/60 (93%)], and spent enough time with them [56/59 (95%)]. However, only 58% (n = 35/60) of respondents agreed or strongly agreed they would like to continue with telehealth and 48% (n = 32/67) agreed telehealth was as effective as in person office visits. Adult survivors were more likely than caregivers to prefer office visits for personal connection [23/32 (72%) vs. 18/39 (46%), p = 0.027].

CONCLUSION

Offering telehealth multi-disciplinary services may provide more efficient and accessible care for a subset of pediatric CNS tumor survivors. Despite some advantages, patients and caregivers were divided on whether they would like to continue with telehealth and whether telehealth was as effective as office visits. To improve survivor and caregiver satisfaction, initiatives to refine patient selection as well as enhance personal communication through telehealth systems should be undertaken.

Risk factors and screening for neurocognitive impacts of therapy

Long-term survivors of pediatric hematologic malignancies are at elevated risk for neurocognitive impairment. Such impairment manifests in different ways at different times during survivorship, with deficits in processing speed, attention, and memory often appearing before deficits in executive function, intelligence, and academics. Survivors exposed to therapies that directly target the central nervous system (CNS), as is the case in acute lymphoblastic leukemia, may demonstrate subtle deficits during frontline therapy, and these deficits may grow and evolve over time. Survivors who do not receive CNS-directed therapies (eg, Hodgkin lymphoma) are also at elevated risk for neurocognitive impairment, although the influence on brain function is indirect through cancer therapy impact on systemic organ function vital to brain health (eg, cardiopulmonary morbidity). Over the course of the survivor's life span, the presence and impact of neurocognitive deficits will be determined by a complex interaction between premorbid development and environment, cancer therapy and clinical care, and posttreatment recovery and health. The timing and type of these treatment and health events will dictate the approach to screening and monitoring for neurocognitive impairment.

A Proposed Link Between Acute Thymic Involution and Late Adverse Effects of Chemotherapy

Epidemiologic data suggest that cancer survivors tend to develop a protuberant number of adverse late effects, including second primary malignancies (SPM), as a result of cytotoxic chemotherapy. Besides the genotoxic potential of these drugs that directly inflict mutational burden on genomic DNA, the precise mechanisms contributing to SPM development are poorly understood. Cancer is nowadays perceived as a complex process that goes beyond the concept of genetic disease and includes tumor cell interactions with complex stromal and immune cell microenvironments. The cancer immunoediting theory offers an explanation for the development of nascent neoplastic cells. Briefly, the theory suggests that newly emerging tumor cells are mostly eliminated by an effective tissue immunosurveillance, but certain tumor variants may occasionally escape innate and adaptive mechanisms of immunological destruction, entering an equilibrium phase, where immunologic tumor cell death "equals" new tumor cell birth. Subsequent microenvironmental pressures and accumulation of helpful mutations in certain variants may lead to escape from the equilibrium phase, and eventually cause an overt neoplasm. Cancer immunoediting functions as a dedicated sentinel under the auspice of a highly competent immune system. This perspective offers the fresh insight that chemotherapy-induced thymic involution, which is characterized by the extensive obliteration of the sensitive thymic epithelial cell (TEC) compartment, can cause long-term defects in thymopoiesis and in establishment of diverse T cell receptor repertoires and peripheral T cell pools of cancer survivors. Such delayed recovery of T cell adaptive immunity may result in prolonged hijacking of the cancer immunoediting mechanisms, and lead to development of persistent and mortal infections, inflammatory disorders, organ-specific autoimmunity lesions, and SPMs. Acknowledging that chemotherapy-induced thymic involution is a potential risk factor for the emergence of SPM demarcates new avenues for the rationalized development of pharmacologic interventions to promote thymic regeneration in patients receiving cytoreductive chemotherapies.

Late effects care for childhood brain Tumor Survivors: A Quality-Improvement Initiative

Childhood and adolescent brain tumor survivors are at risk for long-term consequences of therapy. We reviewed adherence to long-term follow-up (LTFU) guidelines, assessed provider perspectives, and studied the needs, experience and quality of life (QOL) of pediatric malignant brain tumor survivors in the McMaster Children's Hospital Neuro-Oncology clinic. LTFU areas for improvement were evaluated using an anonymous health provider needs assessment questionnaire. The Cancer Care Experience Questionnaire (CCEQ), Cancer Worry Scale (CWS), Self-Management Skills Scale (SMSS), and PedsQL measured parents/patients' needs and QOL. Individual care plans were based on the Children's Oncology Group (COG) LTFU guidelines. Based on 17 responses, staff perceived areas for improvement included: increased multi-disciplinary participation, improved patient education and increased surveillance for therapy-related late effects. Thirty-two families participated, most felt they received high-quality care. Mean cancer worry scores were low (71.8 (± 28.4)). Survivors reported limited self-management skills (58.5 (±18.2)), requiring support with medical needs and activities of daily living. Overall median QOL scores were 'good' (parental report 72.3 (±17.7), survivor 68.2 (±16.6)). Utilizing survivorship guidelines and assessments from patients, caregivers and health providers, we implemented improvements in our provision of neuro-oncology survivorship care. Lessons learned may assist other LTFU programs.

A Mixed-Methods Investigation of Medical Follow-Up in Long-Term Childhood Cancer Survivors: What Are the Reasons for Non-Attendance?

As long-term childhood cancer survivors (CCS) are at risk for late effects, ongoing medical care is crucial to detect and treat physical illnesses as early as possible. However, previous research from around the world has shown that many adult survivors did not participate in long-term medical follow-up. This study aimed to provide insight into German survivors’ care situation, with a particular focus on barriers to follow-up care. We investigated a sample of adult CCS (N = 633) (age M = 34.92; SD = 5.70 years) drawn from the German Childhood Cancer Registry’s oldest cohort (> 25 years after diagnosis). Our analyses included data from a standardized medical examination, a self-report questionnaire, and in-depth interviews with a subsample (n = 43). Half of the participants (n = 314, 49.6%) reported participating in some kind of medical follow-up. In a logistic regression analysis, attendance of medical follow-up care was associated with higher age. Reasons for non-attendance were assigned to four categories: lack of information about medical follow-up and/or its purpose (n = 178), termination by the health care provider (n = 53), structural barriers (n = 21), and emotional-motivational aspects (n = 17). The interviews contributed to a better understanding of how these reported barriers played out in the care of individual survivors. Further, they revealed that some survivors currently in medical follow-up had had periods without follow-up care in the past—which were also in many cases related to a lack of information, both on the part of health care providers and CCS themselves. The results indicated that a large proportion of long-term CCS do not receive the recommended follow-up care. Further, there is a great need for more information regarding the aims of long-term medical follow-up and available offers. This is an important prerequisite for CCS to make informed decisions.

Childhood leukemia and non-Hodgkin's lymphoma survivors lack knowledge about their past disease and possible late effects. I-BFM ELTEC study with Chilean and Croatian participation

PURPOSE

Late effects in childhood cancer survivors are a major cause of morbidity and mortality. The objective was to establish knowledge about the disease, late effects, self-care practices, application of health knowledge/education, sources of information, and biopsychosocial impact of cancer, and compare the results of Chile and Croatia.

METHODS

One-hundred-and-seventy-one, 5-year survivors who were treated for leukemia or non-Hodgkin's lymphoma responded to a questionnaire (119 in Chile and 52 in Croatia). The questionnaire was reviewed by BFM-ELTEC.

RESULTS

Health knowledge about past diagnosis and general treatment had 96% Chilean and 85% Croatian survivors. Ninety percent of Chilean and 73% of Croatian survivors were unaware of possible late effects, and half did not know which specialist to visit for follow-up. Forty-six percent of Chilean and 35% of Croatian survivors knew about healthy lifestyles, but most did not practice them. The 74% of Chileans and 87% of Croatian survivors recalled having received health education during treatment. About 50% of survivors in both groups were afraid or anguish, but it was also a growth experience for 60% of Chilean and 42% of Croatian survivors. Eighty-seven percent Chilean and 77% Croatian survivors considered themselves physically independent, while 76% and 75% felt psychologically independent, respectively.

CONCLUSION

A significant lack of knowledge about the specific treatment, late effects, and future health in both countries was detected. They did not achieve significant learning with the education received. Psychological sequelae were found that are important to prevent.

Emerging and Ongoing Survivorship Challenges Among Childhood Cancer Survivors and Providing Risk-Based Focused Follow-Up Care

OBJECTIVES

To provide a summary of the emerging and ongoing survivorship challenges facing childhood, adolescent, and young adult cancer survivors and their families.

DATA SOURCES

Research and review articles, websites, and clinical guidelines specific to childhood cancer survivorship were used.

CONCLUSION

Many challenges exist in assuring quality long-term follow-up and risk-based screening for childhood cancer survivors. Although many childhood cancer survivors survive well into adulthood, they are at risk for a vast number of later complications of their cancer treatment necessitating annual cancer surveillance. In addition, many childhood cancer survivors are not engaging in long-term follow-up recommendations for clinic attendance, risk-based surveillance, and screening for potentially life-ending events. Pediatric oncology nurses and advanced practice nurses have played an enormous role in the design of childhood cancer survivorship programs and are an integral member of the multidisciplinary health care team who care for this population. Nurses have an obligation to continue to advance the survivorship care of childhood cancer survivors and lead interventional opportunities to improve the lifelong health-related quality of life and overall physical health.

IMPLICATIONS FOR NURSING PRACTICE

Pediatric oncology nurses and advanced practice registered nurses must have a working knowledge of the many late effects that childhood cancer treatment has on the long-term health of childhood cancer survivors. Nurses are well-placed in positions to continue the efforts begun more than 2 decades prior by pediatric oncology nurses who saw the value and necessity of designated survivorship programs.

Patient-reported outcomes in survivors of childhood hematologic malignancies with hematopoietic stem cell transplant

Patient-reported outcomes among survivors of pediatric hematopoietic stem cell transplant (HSCT) are understudied. We compared symptom prevalence, health-related quality of life (HRQOL), and risk factors in adult survivors of childhood hematologic malignancies treated with HSCT to those treated with conventional therapy and noncancer controls. Survivors of childhood hematologic malignancies (HSCT N = 112 [70% allogeneic, 30% autologous]; conventionally treated N = 1106) and noncancer controls (N = 242) from the St. Jude Lifetime Cohort Study completed surveys assessing 10 symptom domains and SF-36 HRQOL summary scores. Chronic health conditions (CHCs) were validated by clinical assessment. Multivariable logistic regression reveals that compared with noncancer controls, HSCT survivors endorsed a significantly higher symptom prevalence in sensation (OR = 4.7, 95% confidence interval [CI], 2.6-8.4), motor/movement (OR = 4.3, 95% CI, 1.6-11.0), pulmonary (OR = 4.6, 95% CI, 1.8-11.8), and memory domains (OR = 4.8, 95% CI, 2.5-9.2), and poorer physical HRQOL (OR = 6.9, 95% CI, 2.8-17.0). HSCT and conventionally treated survivors had a similar prevalence of all symptom domains and HRQOL (all P > .05); however, HSCT survivors had a significantly higher cumulative prevalence for specific symptoms: double vision (P = .04), very dry eyes (P < .0001), and trouble seeing when wearing glasses (P < .0001). Occurrence of organ-specific CHCs, instead of transplant receipt, was significantly associated with a higher prevalence of all symptom domains (all P < .05) in adult survivors of childhood cancer, except for pain and anxiety domains. This study found that patient-reported outcomes were equally impaired between HSCT and conventionally treated survivors, but poorer in both groups compared with noncancer controls. Poor patient-reported outcomes in all survivors of childhood hematologic malignancies correlated with the presence of CHCs, whether treated with conventional therapy or HSCT.

Transfusion-related Iron Overload in Children With Leukemia

BACKGROUND

Children with leukemia commonly receive red blood cell (RBC) transfusions and transfusion-related iron overload (TRIO) is a major complication. However, few studies have evaluated TRIO in children with leukemia and no guidelines for screening exist. This retrospective, observational cohort study in children with acute leukemia evaluates the prevalence of TRIO and its impact on end-organ function.

RESULTS

The study included 139 patients; 60% standard-risk acute lymphoblastic leukemia (ALL), 32% high-risk (HR) ALL, and 9% acute myeloid leukemia (AML). The mean age at diagnosis was 6 years (range: 5 mo to 18 y). Patients with HR-ALL and AML were more likely to be transfused with ≥10 RBC units (59% and 92%, respectively) compared with those with standard-risk ALL (18%) (P<0.0001). Ferritin levels were measured in 68% patients and elevated (>1000 mcg/L) in 23%. Endocrinopathies were the most common end-organ abnormality. Hepatic dysfunction was significantly higher in patients with ≥10 RBC units transfused compared with those with <10 units (P=0.008).

CONCLUSIONS

Although the RBC transfusion burden is highest in patients with AML and HR-ALL, TRIO screening was not commonly performed. Patients who receive ≥10 RBC units are at risk for hepatic and endocrine dysfunction. We recommend routine screening for TRIO in children with leukemia, who are at risk for a higher transfusion burden.

Health Behaviors of Chinese Childhood Cancer Survivors: A Comparison Study with Their Siblings

Purpose: This study aimed to compare health behaviors between the childhood cancer survivors (CCS) and their sibling controls and to examine the pattern of health behaviors of the Hong Kong Chinese CCS and its associations with their health-related quality of life and psychological distress. Methods: A cross-sectional telephone survey was conducted. A total of 614 CCS and 208 sibling controls participated in this study. Patterns of health behaviors including lifestyle behaviors, cancer screening practices, and insurance coverage were compared. Multivariate regression analyses were performed for examining factors associated with health behaviors in CCS. Results: CCS had less alcohol consumption when compared with their sibling controls (adjusted odds ratio (AOR) = 0.65, p = 0.035). The sibling controls were more likely to have cancer screening practices (AOR = 0.38, p = 0.005) and health (AOR = 0.27, p < 0.001) and life insurance coverage (AOR = 0.38, p < 0.001). Among the CCS, those who were male, having a job or higher education, shorter time since diagnosis, and type of cancer suffered were significantly associated with alcohol consumption. Those CCS who were drinkers indicated poorer mental health (p = 0.004) and more psychological distress. Female CCS undertaking cancer screening were more likely to be employed, married/cohabiting, and have received intensive cancer treatment. Conclusion: This study reveals that Chinese childhood cancer survivors are less likely to engage in unhealthy lifestyle behaviors, insurance coverage and cancer screening, when compared with their siblings. Implications for Cancer Survivors: It is crucial for healthcare professionals to identify strategies or target interventions for raising CCS's awareness of their cancer risks and healthy lifestyle throughout their life.

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

PURPOSE

Few studies have compared follow-up-care models for adult survivors of childhood cancer (ASCCs), though choice of model could impact medical test adherence, and health-related quality of life (QOL). This study compared two follow-up-care models, cancer-center-based versus community-based, for ASCCs in Alberta, Canada, to determine which model would demonstrate greater ASCC adherence to guideline-recommended medical screening tests for late effects, QOL, physical symptoms, and adherence to yearly follow-up.

METHODS

ASCC discharged to a community model (over 15 years) and those with comparable birth years (1973-1993) currently followed in a cancer center model were recruited via direct contact or multimedia campaign. Chart review identified chemotherapeutic and radiation exposures, and required medical late effect screening tests. ASCCs also completed questionnaires assessing QOL, physical symptoms, and follow-up behavior.

RESULTS

One hundred fifty-six survivors participated (community (n = 86); cancer center (n = 70)). Primary analysis indicated that cancer center ASCCs guideline-recommended total test adherence percentage (Mdn = 85.4%) was significantly higher than the community model (Mdn = 29.2%, U = 3996.50, p < 0.0001). There was no significant difference in QOL for cancer center ASCCs (M = 83.85, SD = 20.55 versus M = 77.50, SD = 23.94; t (154) = 1.77, p = 0.078) compared to community-based ASCCs. Cancer center-based ASCCs endorsed from 0.4-7.1% fewer physical symptom clusters, and higher adherence to follow-up behavior in comparisons using effect sizes without p values.

CONCLUSION

This study highlights the cancer center model's superiority for adherence to exposure-based medical late effect screening guidelines, cancer-specific follow-up behaviors, and the reporting of fewer physical complaints in ASCCs.

IMPLICATIONS FOR CANCER SURVIVORS

ASCCs followed in a cancer center model likely benefit from earlier late-effects detection and opportunities for early intervention.

Social adjustment of adolescent cancer patients transitioning off active treatment: A short-term prospective mixed methods study

BACKGROUND

Psychosocial follow-up in survivorship is a standard of care in pediatric oncology; however, little is known about patients' psychosocial functioning during the transition off active treatment, a unique time in the cancer journey. This study examined the social adjustment of adolescent cancer patients during this transition period, which has been understudied to date.

PROCEDURE

Participants were 21 patients (ages 12-18 years; age M = 14.71 years; 62% female, 81% White) with various cancer diagnoses. Patients and their parents completed the Social Competence subscale of the Youth Self-Report (YSR) and Child Behavior Checklist (CBCL), respectively, PedsQL Social Functioning subscale, and a semistructured interview 1-2 months prior to ending treatment (time 1) and 3-7 months after ending treatment (time 2).

RESULTS

YSR and CBCL social competence scores were within the normal range at both time points. PedsQL social functioning scores were more consistent with norms for pediatric cancer samples at time 1 and norms for healthy children at time 2, with self-reported scores significantly improving from time 1 to time 2. A subset of patients had elevated social concerns at time 1, a number that decreased by time 2. Interviews revealed both positive and negative themes related to peer relationships and support, quantity of friends, and socialization.

CONCLUSIONS

Most adolescent cancer patients are socially well adjusted as they transition off treatment, although a subset have elevated concerns. Interviews provide insight into complex social experiences not captured on questionnaires. Patients may benefit from screening and support during this unique time.

Population-Based Survey Methods for Reaching Adolescent and Young Adult Survivors of Pediatric Cancer and Their Parents

PURPOSE

Contacting childhood cancer survivors (CCS) to assess reasons for declining receipt of follow-up care after treatment is difficult and participation in surveys may be low, resulting in biased results. We sought to demonstrate effective recruitment and population-based sampling methods to improve response and minimize bias.

METHODS

Four hundred and seventy CCS diagnosed between 2000 and 2007 at two hospitals in Los Angeles County were selected from the California Cancer Registry and were 15-25 years of age at the time of interview. Surveys of survivors and their parents were completed by multiple methods including mail, online, and telephone. Effectiveness of "plain" versus "designer" formatting of study materials was tested. Variables associated with response were analyzed using univariate and multivariable methods. Effort required for recruitment was quantified.

RESULTS

Fifty percent of survivors (n = 235) and 36.5% of parents (n = 171) responded, and there were 160 parent-child dyads among them. Among located survivors, 61% participated. Response was higher for women, parents of younger survivors, and those from higher socioeconomic status areas. Among Hispanics, no variables were related to response. More effort was required to reach men and older survivors, but efforts beyond 15 calls and 7 remailings were unproductive. Formatting (i.e., plain vs. designer) did not affect response.

CONCLUSION

Efforts to reach survivors must include multiple methods to be successful. Use of an intensive recruitment strategy and population-based sample resulted in a largely representative sample of CCS, especially for Hispanics. Expensive design efforts had little effect on recruitment, suggesting that plainer materials are sufficient. This example may inform similar studies.

Review of risk factors of secondary cancers among cancer survivors

Improvements in cancer survival have made the long-term risks from treatments more important, in particular among the children, adolescents and young adults who are more at risk particularly due to a longer life expectancy and a higher sensitivity to treatments. Subsequent malignancies in cancer survivors now constitute 15 to 20% of all cancer diagnoses in the cancer registries. Lots of studies are published to determine risk factors, with some controversial findings. Just data from large cohorts with detailed information on individual treatments and verification of what is called "secondary cancers" can add some knowledge, because their main difficulty is that the number of events for most second cancer sites are low, which impact the statistical results. In this review of the literature, we distinguish second and secondary cancers and discuss the factors contributing to this increased risk of secondary cancers. The article concludes with a summary of current surveillance and screening recommendations.

Assessment of end-of-treatment transition needs for pediatric cancer and hematopoietic stem cell transplant patients and their families

BACKGROUND/OBJECTIVES

The transition off active treatment is a time of significant stress for pediatric cancer patients and families. Providing information and support at this time is among the new psychosocial standards of care in pediatric oncology. This study sought to explore patient and family needs and concerns at the end of their active cancer treatment.

DESIGN/METHODS

Forty-nine caregiver-child dyads completed semi-structured interviews and surveys 1-2 months before ending treatment, and again 3-7 months after treatment concluded.

RESULTS

Patients and caregivers reported a moderate level of understanding of follow-up care needs, late effects, and perceived preparation. Altogether, child, adolescent, and young adult cancer patients and parents identified similar priorities for information needed during the transition off active treatment. The most essential pieces of information desired by patients and families across time points included reviews of late effects, schedules for follow-up care, health and physical restrictions, communication with the patient's primary care provider, and provision of a treatment summary. At Time 2, patients and families reported a greater retrospective desire for emotional health resources. Most patients and caregivers wanted information from a variety of sources, but the desired timing to receive this information varied and was dependent on disease group.

CONCLUSIONS

There are many essential components to end-of-treatment care that are not consistently provided to pediatric cancer patients and families. Formalized programs offering education and support should be provided by multidisciplinary teams prior to the end of active treatment.

Healthcare system barriers to long-term follow-up for adult survivors of childhood cancer in British Columbia, Canada: a qualitative study

PURPOSE

Risk-stratified life-long follow-up care is recommended for adult childhood cancer survivors (CCS) to ensure appropriate prevention, screening, and management of late effects. The identification of barriers to long-term follow-up (LTFU), particularly in varying healthcare service contexts, is essential to develop and refine services that are responsive to survivor needs. We aimed to explore CCS and healthcare professionals (HCP) perspectives of healthcare system factors that function as barriers to LTFU in British Columbia, Canada.

METHODS

We analyzed data from 43 in-depth interviews, 30 with CCS and 13 with HCP, using qualitative thematic analysis and constant comparative methods.

RESULTS

Barriers to accessible, comprehensive, quality LTFU were associated with the following: (1) the difficult and abrupt transition from pediatric to adult health services, (2) inconvenient and under-resourced health services, (3) shifting patient-HCP relationships, (4) family doctor inadequate experience with late effects management, and (5) overdue and insufficient late effects communication with CCS.

CONCLUSIONS

Structural, informational, and interpersonal/relational healthcare system factors often prevent CCS from initially accessing LTFU after discharge from pediatric oncology programs as well as adversely affecting engagement in ongoing screening, surveillance, and management of late effects.

IMPLICATIONS FOR CANCER SURVIVORS

Understanding the issues faced by adult CCS will provide insight necessary to developing patient-centered healthcare solutions that are key to accessible, acceptable, appropriate, and effective healthcare.

Health status of Polish children and adolescents after cancer treatment

In the last 40 years, considerable progress was made in the treatment of childhood cancer. Nearly 80% of children achieve long-term clinical remission or are permanently cured. This improvement is however not without sacrifice. This is the first Polish study analyzing the general health status and epidemiology of organ late effects in the cohort of Polish childhood and adolescent cancer survivors monitored by doctors and registered in the on-line national database for late effects (N = 1761). This tool collects information on previous therapy and current health status (medical history, physical examination, laboratory tests) of cancer survivors. The survivors are invited to take part in the follow-up examination 5 years after the end of treatment. In the study group, 207 survivors (11.75%) had no complaints; whereas in 1554 cases (88.25%), one or more symptoms/complaints suggesting organ dysfunction were reported. In the whole group, the circulatory problems were most common (31.7%); more than 20% of survivors presented complaints or abnormal function of the urinary tract and had skin, dental, skeletal/muscular problems, or difficulty with chewing. Obesity or short stature alone (21.4%) and a variety of endocrine problems (short stature, obesity, thyroid dysfunction, and gonads toxicity) were present in 323 patients (118 females 15.0% and 205 males 21.0%). Gonadal dysfunction, as the only problem, occurred in 75 girls (9.6%) and 131 boys (13.4%). In our cohort, severe or life-threatening health conditions (3 and 4 grade according to toxicity criteria) were present in low percentage, i.e., 0.2% in the circulatory system, 0.3% in the respiratory tract and, 0.7% in kidney insufficiency.

CONCLUSION

Our findings indicate that many childhood cancer survivors demonstrate numerous complaints, even a short time after treatment, suggesting the importance of regular follow-up examinations in subsequent years. What is Known: • Contemporary studies indicate that a significant number of childhood cancer survivors present different long-term side effects which influence their quality of life. What is New: • This is the first nationwide study performed in the largest cohort of Polish childhood cancer survivors concerning general health status and frequency of organ dysfunction.

Children with cancer: a survey on the experience of Italian primary care pediatricians

BACKGROUND

Cancer is the second cause of death in children and its diagnosis can be difficult, due to the presence of vague and non-specific symptoms. The primary care pediatrician is often involved in the diagnostic process, but no longer in child care once the treatment started. Care models involving both primary care pediatricians and oncologic referral centre highlighted a higher family satisfaction when they worked together. We conducted a survey on primary care pediatricians involved in childhood cancer in order to describe the actual situation.

METHODS

We conducted a retrospective survey enrolling primary care pediatricians from a north-eastern area of Italy. They received a questionnaire that consisted in two parts: the first one aimed to assess the physician's seniority and experience and the second one pertained to each case of cancer and explored the relationship between the pediatrician, the family and the referral centre, and pediatricians degree of satisfaction and emotional impact.

RESULTS

We obtained data from 79 pediatricians who described 150 cancer cases. In 99 cases the primary care pediatrician had visited the child at the onset of symptoms and had referred him to the hospital. In 89 cases, he understood the severity of the disease. In 53.3% of cases the pediatrician was informed by the referral centre. The relationship between the pediatrician and child's family improved in 38% of cases and this was related with their participation to the multidisciplinary meetings on child health.

CONCLUSIONS

Primary pediatricians' sharing in the management of their patients with cancer was not satisfactory. Development of specific protocols targeted to an integrated care is needed to increase primary pediatricians' involvement and families' satisfactions.

Comparison of mandibular cortical thickness and QCT-derived bone mineral density (BMD) in survivors of childhood acute lymphoblastic leukemia: a retrospective study

OBJECTIVE

To examine whether panoramic radiograph-determined mandibular cortical thickness correlated with quantitative computed tomography-derived bone mineral density (BMD) in survivors of childhood acute lymphoblastic leukemia (ALL).

METHODS

We identified patients treated for ALL at St. Jude Children's Research Hospital, seen in the After Completion of Therapy (ACT) Clinic between January of 2006 and January of 2014 who had QCT-derived BMD and panoramic radiographs obtained within 1 month of each other. Panoramic radiographs were independently scored by a pediatric radiologist, two pediatric dentists, and a general dentist using the Klemetti technique. We used the Spearman's rank correlation test and the multivariate regression model to investigate the effect of evaluator experience on results.

RESULTS

The study cohort comprised 181 patients with 320 paired studies: 112 (62%) male, 112 (71%) were white. Median age at ALL diagnosis was 6.4 (range, 0-18.8) years. Median age at study was 11.9 (range, 3.3 to 29.4) years. The median average BMD was 154.6 (range, 0.73-256) mg/cc; median QCT Z-score (age and gender adjusted) was -0.875 (range, -5.04 to 3.2). We found very weak association between panoramic radiograph score and both QCT-BMD average (P = 0.53) and QCT Z-score (P = 0.39). Results were not influenced by level of reader experience.

CONCLUSIONS

The Klemetti technique of estimating BMD does not predict BMD deficits in children and young adult survivors of ALL, regardless of reviewer expertise. Alternative methods are needed whereby dental healthcare providers can identify and refer patients at risk for BMD deficits for detailed assessment and intervention.

Nutritional interventions for survivors of childhood cancer

BACKGROUND

Childhood cancer survivors are at a higher risk of developing health conditions such as osteoporosis, and cardiovascular disease than their peers. Health-promoting behaviour, such as consuming a healthy diet, could lessen the impact of these chronic issues, yet the prevalence rate of health-protecting behaviour amongst survivors of childhood cancer is similar to that of the general population. Targeted nutritional interventions may prevent or reduce the incidence of these chronic diseases.

OBJECTIVES

The primary aim of this review was to assess the efficacy of a range of nutritional interventions designed to improve the nutritional intake of childhood cancer survivors, as compared to a control group of childhood cancer survivors who did not receive the intervention. Secondary objectives were to assess metabolic and cardiovascular risk factors, measures of weight and body fat distribution, behavioural change, changes in knowledge regarding disease risk and nutritional intake, participants' views of the intervention, measures of health status and quality of life, measures of harm associated with the process or outcomes of the intervention, and cost-effectiveness of the intervention

SEARCH METHODS

We searched the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL; 2013, Issue 3), MEDLINE/PubMed (from 1945 to April 2013), and Embase/Ovid (from 1980 to April 2013). We ran the search again in August 2015; we have not yet fully assessed these results, but we have identified one ongoing trial. We conducted additional searching of ongoing trial registers - the International Standard Randomised Controlled Trial Number register and the National Institutes of Health register (both screened in the first half of 2013) - reference lists of relevant articles and reviews, and conference proceedings of the International Society for Paediatric Oncology and the International Conference on Long-Term Complications of Treatment of Children and Adolescents for Cancer (both 2008 to 2012).

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) that compared the effects of a nutritional intervention with a control group which did not receive the intervention in this review. Participants were childhood cancer survivors of any age, diagnosed with any type of cancer when less than 18 years of age. Participating childhood cancer survivors had completed their treatment with curative intent prior to the intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected and extracted data from each identified study, using a standardised form. We assessed the validity of each identified study using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We used the GRADE criteria to assess the quality of each trial.

MAIN RESULTS

Three RCTs were eligible for review. A total of 616 participants were included in the analysis. One study included participants who had been treated for acute lymphoblastic leukaemia (ALL) (275 participants). Two studies included participants who had all forms of paediatric malignancies (266 and 75 participants). All participants were less than 21 years of age at study entry. The follow-up ranged from one month to 36 months from the initial assessment. All intended outcomes were not evaluated by each included study. All studies looked at different interventions, and so we were unable to pool results. We could not rule out the presence of bias in any of the studies.There was no clear evidence of a difference in calcium intake at one month between those who received the single, half-day, group-based education that focused on bone health, and those who received standard care (mean difference (MD) 111.60, 95% confidence interval (CI) -258.97 to 482.17; P = 0.56, low quality evidence). A regression analysis, adjusting for baseline calcium intake and changes in knowledge and self-efficacy, showed a significantly greater calcium intake for the intervention as compared with the control group at the one-month follow-up (beta coefficient 4.92, 95% CI 0.33 to 9.52; P = 0.04). There was statistically significant higher, self-reported milk consumption (MD 0.43, 95% CI 0.07 to 0.79; P = 0.02, low quality evidence), number of days on calcium supplementation (MD 11.42, 95% CI 7.11 to 15.73; P < 0.00001, low quality evidence), and use of any calcium supplementation (risk ratio (RR) 3.35, 95% CI 1.86 to 6.04; P < 0.0001, low quality evidence), with those who received this single, face-to-face, group-based, health behaviour session.There was no clear evidence of a difference in bone density Z-scores measured with a dual-energy X-ray absorptiometry (DEXA) scan at 36 months follow-up (MD -0.05, 95% CI -0.26 to 0.16; P = 0.64, moderate quality evidence) between those who received calcium and vitamin D supplementation combined with nutrition education and those who received nutrition education alone. There was also no clear evidence of a difference in bone mineral density between the intervention and the control group at the 12-month (median difference -0.17, P = 0.99) and 24-month follow-up (median difference -0.04, P = 0.54).A single multi-component health behaviour change intervention, focusing on general healthy eating principles, with two telephone follow-ups brought about a 0.17 lower score on the four-point Likert scale of self-reported junk food intake compared with the control group (MD -0.17, 95% CI -0.33 to -0.01; P = 0.04, low quality evidence); this result was statistically significant. There was no clear evidence of a difference between the groups in the self-reported use of nutrition as a health protective behaviour (MD -0.05, 95% CI -0.24 to 0.14; P = 0.60, low quality evidence).

AUTHORS' CONCLUSIONS

Due to a paucity of studies, and the heterogeneity of the studies included in this review, we are unable to draw conclusions regarding the effectiveness of nutritional interventions for use with childhood cancer survivors. Although there is low quality evidence for the improvement in health behaviours using health behaviour change interventions, there remains no evidence as to whether this translates into an improvement in dietary intake. There was also no evidence that the studies reduced the risk of cardiovascular and metabolic disorders in childhood cancer survivors, although no evidence of effect is not the same as evidence of no effect. This review highlights the need for further well designed trials to be implemented in this population.

Support from healthcare services during transition to adulthood - Experiences of young adult survivors of pediatric cancer

PURPOSE

Improved survival rates of pediatric cancer have drawn attention on how to best facilitate long-term follow up and transition from pediatric to adult care. The transition process is multifactorial and necessitates the joint involvement of the patient, the family and the healthcare providers. The purpose of this study was to explore the experiences of support from healthcare services during the transition from adolescence to adulthood described by young adult survivors of pediatric cancer.

METHODS

A mixed method with a convergent parallel design was used to evaluate the experiences of receiving support from healthcare services (eg pediatric oncology and pediatric clinic) during transition from adolescence to adulthood described by young adult survivors of pediatric cancer (n = 213) in a nation wide cross-sectional survey.

RESULTS

A quantitative assessment of the experienced extent and satisfaction of support from healthcare services to handle physical, mental and social changes to continue life after the disease showed that a majority of the participants had received insufficient support. The qualitative analysis indicated a need for equal roles in healthcare to promote participation, a need to manage and process consequences of the disease, and a need for continuous support.

CONCLUSIONS

During transition to adulthood, there's a need for a personalized care plan that takes a holistic approach towards supporting the young cancer survivor in managing life in the best way. Identifying and handling the individual needs of pediatric cancer survivors is important for providing the resources and support required to increase the likelihood of successful transition to adulthood.

Long-Term Neurocognitive Functioning and Social Attainment in Adult Survivors of Pediatric CNS Tumors: Results From the St Jude Lifetime Cohort Study

PURPOSE

To assess the prevalence and severity of neurocognitive impairment in adult survivors of pediatric CNS tumors and to examine associated treatment exposures.

PATIENTS AND METHODS

Participants included 224 survivors of CNS tumors who were treated at St Jude Children's Research Hospital (current median age [range], 26 years [19 to 53 years]; time from diagnosis, 18 years [11 to 42 years]) and completed neurocognitive testing. Information on cranial radiation therapy (CRT) doses and parameters of delivery were abstracted from medical records. The prevalence of severe impairment (ie, at least two standard deviations below normative mean) was compared across radiation treatment groups (no CRT, focal irradiation, craniospinal irradiation) using the χ(2) test. Log-binomial models were used to estimate risk ratios (RRs) and corresponding 95% CIs for severe impairment.

RESULTS

In multivariable models, craniospinal irradiation was associated with a 1.5- to threefold increased risk of severe impairment compared with no CRT (eg, intelligence: RR = 2.70; 95% CI, 1.37 to 5.34; memory: RR = 2.93; 95% CI, 1.69 to 5.08; executive function: RR = 1.74; 95% CI, 1.24 to 2.45). Seizures were associated with impaired academic performance (RR = 1.48; 95% CI, 1.02 to 2.14), attention (RR = 1.54; 95% CI, 1.12 to 2.13), and memory (RR = 1.44; 95% CI, 1.04 to 1.99). Hydrocephalus with shunt placement was associated with impaired intelligence (RR = 1.78; 95% CI, 1.12 to 2.82) and memory (RR = 1.42; 95% CI, 1.03 to 1.95). Differential follow-up time contributed to variability in prevalence estimates between survivors treated with older nonconformal and those treated with more contemporary conformal radiation therapy methods. Neurocognitive impairment was significantly associated with lower educational attainment, unemployment, and nonindependent living.

CONCLUSION

Survivors of pediatric CNS tumors are at risk of severe neurocognitive impairment in adulthood. The prevalence of severe impairment is greater than expected in the general population, even in the absence of CRT, and is associated with disrupted attainment of adult social milestones.

Adult childhood cancer survivors' narratives of managing their health: the unexpected and the unresolved

Purpose

Currently, 80 % of children diagnosed with cancer will be cured. However, many of these survivors go on to develop long-term health problems or late effects related to their previous cancer and therapy and require varying degrees of lifelong follow-up care. The purpose of this study was to identify the different ways that adult survivors of childhood cancer manage their medical and psychological challenges.

Methods

Data from in-depth interviews with 30 adult survivors of a childhood cancer (9 to 38 years after diagnosis, currently 22 to 43 years of age, 60 % women) were analyzed using qualitative, thematic narrative analysis methods.

Results

The survivors had not expected the medical, psychological, and social challenges that arose over time and that often remained unresolved. Five narrative themes revealed distinct ways that survivors managed their health challenges: (1) trying to forget cancer, (2) trusting the system to manage my follow-up care, (3) being proactive about my health, (4) stumbling from one problem to the next, and (5) struggling to find my way.

Conclusions

Variation exists in the ways in which childhood cancer survivors frame their health, their perceived significance of health challenges, strategies used to manage health, interactions with healthcare professionals and the health system, and parental involvement.

Implications for Cancer Survivors

This research provides novel insights that can be used to inform the development of patient-centered health services that promote the assessment and tailoring of care to the diverse ways survivors enact their agency, as well as their psychoeducational coping styles, therapeutic relationship needs, and information needs.

Psychosocial Follow-Up in Survivorship as a Standard of Care in Pediatric Oncology

Childhood cancer survivors (CCS) have a high risk of medical late effects following cancer therapy. Psychosocial late effects are less often recognized. Many CCS do not receive long-term follow-up (LTFU) care, and those who do are rarely screened for psychosocial late effects. An interdisciplinary team conducted a systematic review of qualitative and quantitative studies to assess social, educational, vocational, psychological, and behavioral outcomes along with factors related to receipt of LTFU care. We propose that psychosocial screening be considered a standard of care in long-term follow-up care and that education be provided to promote the use LTFU care starting early in the treatment trajectory.

Providing Information About Late Effects During Routine Follow-Up Consultations Between Pediatric Oncologists and Adolescent Survivors: A Video-Based, Observational Study

PURPOSE

Information about late effects is a prerequisite for survivors of childhood cancers to engage in self-management of their health. Yet, many lack such knowledge. This study investigated to what extent: (1) potential late effects were discussed with adolescent and young adult (AYA)-aged survivors (of pediatric cancer), and (2) information about late effects was provided by the pediatric oncologists (POs) during routine follow-up consultations.

METHODS

Consultations were recorded with 10 POs and 66 adolescents, aged 12-20 years, treated for leukemia (72.7%) or lymphoma (21.2%), or who had received hematopoietic stem-cell transplantation for a benign disease (7.6%). Discussions of potential late effects were identified and coded, and then the amount of information about late effects provided was categorized into three levels: none, basic, and extended information.

RESULTS

Potential late effects were discussed in 85% of the consultations. Of these, 71% were PO initiated, and 60% concerned existing health problems. The POs provided none, basic, and extended information about late effects in 41%, 30%, and 29% of these discussions. Patients' age, time since treatment, and risk of late effects were not associated with amount of potential late effects discussed, but the type of potential late effect (physical vs. psychosocial and current vs. future risk) and PO were.

CONCLUSION

Potential late effects were frequently discussed, thus providing ample opportunity to provide information about late effects to adolescent cancer survivors. The observed PO variability in providing such information indicates a need for standardization of information practices.

Preparing for the future: An examination of healthcare provider and patient communication regarding childhood cancer survivorship

BACKGROUND

This qualitative, exploratory study examines the content of communication between healthcare providers (HCP) and childhood cancer patients (CCP) during a medical appointment to evaluate the extent to which cancer survivorship issues (medical and psychosocial) are discussed.

METHODS

The content of the communication for 16 CCP ages 10-22 and their HCP were examined via audio recorded medical appointments occurring within 6 months of the end of active cancer treatment. The data were analysed using template analysis, a constructivist-interpretivist qualitative approach.

RESULTS

HCP addressed more medically focused than psychosocially focused issues related to survivorship.

CONCLUSIONS

Most discussions of survivorship are medically focused, potentially leaving patients with little information about future psychosocial functioning. Recommendations for future research on enhancing discussions about psychosocial issues are presented. This research has the potential to inform future interventions to enhance patient-provider communication on survivorship issues.

Strategies to improve the quality of survival for childhood brain tumour survivors

BACKGROUND

Tumours of the central nervous system (CNS) are the most frequent solid tumours and the second most frequent type of cancer in children and adolescents. Overall survival has continuously improved in Germany, since an increasing number of patients have been treated according to standardised, multicentre, multimodal treatment recommendations, trials of the German Paediatric Brain Tumour Consortium (HIT-Network) or the International Society of Paediatric Oncology-Europe (SIOP-E) during the last decades. Today, two out of three patients survive. At least 8000 long-term childhood brain tumour survivors (CBTS) are currently living in Germany. They face lifelong disease- and treatment-related late effects (LE) and associated socioeconomic problems more than many other childhood cancer survivors (CCS).

METHOD

We review the LE and resulting special needs of this particular group of CCS.

RESULTS

Despite their increasing relevance for future treatment optimisation, neither the diversity of chronic and cumulative LE nor their pertinent risk factors and subsequent impact on quality of survival have yet been comprehensively addressed for CBTS treated according to HIT- or SIOP-E-protocols. Evidence-based information to empower survivors and stakeholders, as well as medical expertise to manage their individual health care, psychosocial and educational/vocational needs must still be generated and established.

CONCLUSION

The establishment of a long-term research- and care network in Germany shall contribute to a European platform, that aims at optimising CBTSs' transition into adulthood as resilient individuals with high quality of survival including optimal levels of activity, participation and acceptance by society.

Impact of Tailored Education on Awareness of Personal Risk for Therapy-Related Complications Among Childhood Cancer Survivors

Purpose

Survivors of childhood cancer carry a substantial burden of long-term morbidity; personal risk awareness is critical to ensure survivors' engagement in early detection/management of complications. The impact of education provided in survivorship clinics on survivors' understanding of their personal health risks is unclear.

Methods

Patients diagnosed with cancer at age 21 years or younger and at 2 or more years off therapy completed questionnaires about awareness of personal risk for therapy-related complications at T0 (first survivorship clinic visit) and at T1 to T5 (subsequent visits). After questionnaire completion at each clinic visit, survivors received education tailored to personal risk.

Results

A total of 369 survivors completed 1,248 visits (median, three visits; range, one to six visits). The median age at cancer diagnosis was 11 years (range, 0 to 21 years); the median age at T0 was 24 years (range, 5 to 57 years); 38% were white; 45% had leukemia; and 34% received hematopoietic cell transplantation. The cohort was at risk for a median of six (range, one to nine) complications. Awareness increased from 38.6% at T0 to 66.3% at T3. Generalized estimating equations (that adjusted for diagnosis, hematopoietic cell transplantation, race/ethnicity, and patient/parent education) showed significant gains in awareness from T0 to T1 (P < .001), T1 to T2 (P = .03), and T2 to T3 (P < .001) but no significant gain thereafter through T5 (P = .7). Predictors of low awareness included education less than a college degree (odds ratio [OR], 1.9; P = .02), longer time from diagnosis (OR, 1.03/year; P = .04), diagnosis of leukemia (OR, 2.1; P = .004), nonwhite race (OR, 2.8; P < .001), and risk for six or fewer complications (OR, 2.1; P = .002).

Conclusion

Risk-based education in a survivorship clinic significantly increases awareness of personal health risk through three sessions, with saturation thereafter. Vulnerable populations with minimal gain in awareness identified in this study could inform targeted interventions.

Knowledge of diagnosis, treatment history, and risk of late effects among childhood cancer survivors and parents: The impact of a survivorship clinic

BACKGROUND

Childhood cancer survivors are at risk for treatment-related adverse health outcomes, known as late effects. Through matched and longitudinal cohorts, we assessed the impact of survivorship care on patient and parent knowledge of treatment history and associated health risks.

PROCEDURE

Childhood cancer survivors were recruited from a single-institution survivorship clinic and matched with survivors receiving routine follow-up care (controls) on diagnosis, age, and time off therapy. One hundred seventy-four participants completed telephone interviews assessing knowledge of diagnosis, treatment history, and risk of late effects. Additionally, 48 new survivorship patients were followed longitudinally with serial interviews for 18 months.

RESULTS

In the case-control study, survivorship participants were more likely than controls to correctly report their diagnosis (98% vs. 90%, P = 0.039) and indicate a previous discussion of risk of late effects (99% vs. 62%, P<0.0001). Compared to controls, survivorship participants were 13% more sensitive reporting chemotherapeutics (95%CI 2.8-23.7%, P = 0.013) and 12% more sensitive reporting late effect risk (95%CI 7.3-16.6%, P<0.0001). In the longitudinal cohort, participants were 7% more sensitive reporting chemotherapeutics (95%CI 5.4-10.8%, P < 0.001) and 9% more sensitive reporting late effect risk (95%CI 5.6-23.8%, P<0.001) at 3 months compared to baseline. In regression analysis, baseline knowledge correlated with subsequent interview performance, and time since survivorship visit correlated with decreased knowledge of late effects, but not diagnosis or treatment history.

CONCLUSIONS

Survivorship care was associated with increased knowledge of diagnosis, treatment history, and risk of late effects in both cohorts. Knowledge of late effects decreases with time, suggesting the need for additional educational strategies.

Effect of cancer treatment on hypothalamic-pituitary function

The past 30 years have seen a great improvement in survival of children and young adults treated for cancer. Cancer treatment can put patients at risk of health problems that can develop many years later, most commonly affecting the endocrine system. Patients treated with cranial radiotherapy often develop dysfunction of the hypothalamic-pituitary axis. A characteristic pattern of hormone deficiencies develops over several years. Growth hormone is disrupted most often, followed by gonadal, adrenal, and thyroid hormones, leading to abnormal growth and puberty in children, and affecting general wellbeing and fertility in adults. The severity and rate of development of hypopituitarism is determined by the dose of radiotherapy delivered to the hypothalamic-pituitary axis. Individual growth hormone deficiencies can develop after a dose as low as 10 Gy, whereas multiple hormone deficiencies are common after 60 Gy. New techniques in radiotherapy aim to reduce the effect on the hypothalamic-pituitary axis by minimising the dose received. Patients taking cytotoxic drugs do not often develop overt hypopituitarism, although the effect of radiotherapy might be enhanced. The exception is adrenal insufficiency caused by glucocorticosteroids which, although transient, can be life-threatening. New biological drugs to treat cancer can cause autoimmune hypophysitis and hypopituitarism; therefore, oncologists and endocrinologists should be vigilant and work together to optimise patient outcomes.

Providing information about late effects after childhood cancer: lymphoma survivors' preferences for what, how and when

OBJECTIVE

Childhood cancer survivors need information about risks of late effects to manage their health. We studied how and when adult, long-term survivors prefer to receive information about late effects.

METHODS

Five focus-groups with adult survivors of childhood lymphomas who had completed routine follow-up care and participated in a preceding follow-up study (n = 34, 19 females, mean age = 39). We used thematic analysis to identify themes regarding providing late effects information.

RESULTS

The survivors wanted information about late effects (symptoms, prevention and treatment), lifestyle and social security rights. Information should be tailored, carefully timed, given "face-to-face" and in written format. Many expressed ambivalence regarding receiving information as adolescents, but it was seen as essential "to know" once a late effect occurred. A "re-information" consultation about late effects around age 25 was suggested as beneficial.

CONCLUSION

Although ambivalent, all survivors wanted information about late effects. They preferred individualized information, disclosed "step-by-step" and in a "re-information consultation" when reaching young adulthood.

PRACTICE IMPLICATIONS

Providing information about late effects should be an on-going process across the cancer care trajectory. (Re-)Informing survivors when older would enhance their understanding of their health risks and could aid better health self-management beyond completion of follow-up care.

Experiencing reproductive concerns as a female cancer survivor is associated with depression

BACKGROUND

Young adult female cancer survivors have unmet reproductive concerns and informational needs that are associated with poorer quality of life. The purpose of this study was to examine the association between current reproductive concerns and moderate to severe depression among young survivors.

METHODS

This cross-sectional study included 200 female cancer survivors between the ages of 18 and 35 years who completed a Web-based survey measuring reproductive history, parenthood desires, reproductive concerns after cancer, and quality-of-life indicators.

RESULTS

The mean age of the participants was 28 years (standard deviation, 4.4 years), and almost two-thirds were diagnosed within 5 years of survey completion. A multivariate logistic regression analysis controlling for education, duration of survivorship, and social support revealed an association between experiencing reproductive concerns and moderate to severe depression (odds ratio for each 5-unit increase in the Reproductive Concerns After Cancer [RCAC] score, 1.30; 95% confidence interval, 1.06-1.60). Among those with moderate to severe depression, 23% had high RCAC scores, whereas 6% of those with minimal to mild depression did (P < .001).

CONCLUSIONS

A higher level of reproductive concerns was associated with greater odds of experiencing moderate to severe depression. Almost a quarter of survivors in this sample reported moderate to severe depression, and addressing reproductive concerns represents one potential area of intervention for improving the psychosocial health of young survivors.

Comparison of diabetes management status between cancer survivors and the general population: results from a Korean population-based survey

Purpose

This study aimed to determine and compare the prevalences of diabetes awareness, treatment, and adequate glycemic control among cancer survivors in a Korean population and two non-cancer control groups, comprising individuals without a history of cancer but with other chronic diseases (non-cancer, chronic disease controls) and individuals without a history of cancer or any other chronic disease (non-cancer, non-chronic disease controls).

Methods

We analyzed data from 2,660 subjects with prevalent diabetes (aged ≥30 years), who had participated in the 2007–2011 Korea National Health and Nutrition Examination Survey. Awareness was defined as a subject having been diagnosed with diabetes by a clinician. Treatment was defined as a subject who was taking anti-diabetic medicine. Adequate glycemic control was defined as a hemoglobin A1_c level of <7%. Multivariable logistic regression and predictive margins were used to evaluate whether awareness, treatment, or adequate glycemic control differed among cancer survivors and the two non-cancer control groups.

Results

Cancer survivors had greater awareness compared with the non-cancer, chronic disease and non-cancer, non-chronic disease control groups (85.1%, 80.4%, and 60.4%, respectively). Although the prevalences of treatment and adequate glycemic control were higher for survivors compared with the non-cancer, non-chronic disease controls, they were lower compared with the non-cancer, chronic disease controls. The prevalence of diabetes treatment was 67.5% for cancer survivors, 69.5% for non-cancer, chronic disease controls, and 46.7% for non-cancer, non-chronic disease controls; the prevalences of adequate glycemic control in these three groups were 31.7%, 34.6%, and 17.8%, respectively.

Conclusions

Cancer survivors were less likely than the non-cancer chronic disease subjects to receive diabetes management and to achieve adequate glycemic targets. Special attention and education are required to ensure that this population receives optimal diabetes care, and the systematic roles for primary care and specialist physicians need to be determined.

Perceptions of body mass index (BMI) in pediatric cancer survivors and their providers

BACKGROUND

Abnormalities in BMI are well documented in childhood cancer survivors. Perceptions of BMI status in cancer survivors have been understudied. This study determines the accuracy of parent/survivor and provider reporting of BMI status in a cancer survivor program.

PROCEDURE

This is a retrospective study. Parent/survivor assessment of BMI status was obtained from a baseline questionnaire of subjects enrolled in Children's Healthcare of Atlanta-Childhood, Adolescent, and Young Adult Cancer Survivor Study (CHOA-CAYACSS). Provider reporting of BMI was obtained from a clinic visit close in date to completion of the survey. Perceptions of BMI were compared to actual BMI status calculated from clinic visits and categorized based on the Centers for Disease Control and Prevention (CDC) BMI guidelines.

RESULTS

Perceptions of BMI were collected from 290 survivors of pediatric cancer or their parents (range, 4.3-22.9 years). Nearly 5% of survivors were underweight, 19.7% overweight and 16.2% obese. High BMI was the BMI state least likely to be correctly identified by parents, survivors, and providers. Among survivors with high BMI, parents, survivors, and providers failed to identify the problem 49.4%, 66.7%, and 26.9% of the time, respectively. Providers were less likely to correctly identify overweight compared to obese status (P < 0.0001). Accuracy of BMI recognition was independent of gender of survivor, ethnicity, or primary cancer diagnosis.

CONCLUSION

Abnormal BMI states, especially overweight, are frequently not correctly perceived by parents/survivors or providers. Assessment of BMI status and discussion about steps to normalize BMI is needed to prevent weight related morbidities in this population.

Screening for vitamin D insufficiency in pediatric cancer survivors

BACKGROUND

Corticosteroids increase risk for decreased bone mineral density, which can be worsened by vitamin D insufficiency (VDI) or deficiency (VDD).

PROCEDURE

In the Vanderbilt cancer survivorship clinic, we obtained screening total 25-hydroxy vitamin D levels (VDL) in 171 cancer survivors <23 years old who were treated with prolonged corticosteroids for their cancer, and compared this group to a control group of 97 healthy pediatric patients.

RESULTS

VDD was diagnosed in 15.8% and VDI in 34.5% of cancer survivors and VDD/VDI combined was associated with body mass index (BMI) >85th percentile (Odds ratio [OR] = 5.4; P < 0.001), older age (OR = 2.2; P = 0.012), non-Caucasian or Hispanic race (OR = 4.5; P = 0.008) and summer versus winter season (OR = 0.12; P < 0.001). In multivariable analysis, VDI/VDD prevalence did not differ from the control group (VDI/VDD (43.3%)). In the combined survivor/control group multivariable analysis, cancer diagnosis did not increase VDI/VDD risk, but significant associations persisted with elevated BMI (P < 0.001), age (P = 0.004), non-Caucasian or Hispanic race (P < 0.001), and seasonality (P < 0.001).

CONCLUSION

VDD/VDI is equally common in pediatric cancer survivors treated with corticosteroids and healthy children. The impact of VDD/VDI in cancer survivors may be greater due to risk for impaired bone health superimposed on that conferred from corticosteroid exposure. Thus, screening VDLs should be obtained in pediatric cancer survivors treated with corticosteroids, particularly in those with elevated BMI, older age, or non-Caucasian race. Prospective studies evaluating the impact of interventions to minimize VDD/VDI on long-term bone health in survivors are required.

College health as a partner in the care of pediatric cancer survivors

OBJECTIVE

This study reviews an initiative to educate providers on pediatric cancer survivor care and to establish a cancer survivor registry in a college health center.

PARTICIPANTS

PARTICIPANTS were University of Georgia (UGA) college health providers.

METHODS

Providers attended lectures on survivor care and were encouraged to register on Cancer SurvivorLink. Changes in provider familiarity and practice were measured using baseline and follow-up surveys. A survivor registry was created using health entrance forms and medical records abstraction.

RESULTS

Twenty-four providers registered on SurvivorLink, and 16 completed both surveys. Familiarity with survivor care (p = .003) and a survivor health care plan (p = .016) increased. Likelihood to deliver survivor care increased (p = .01). UGA follows 95 survivors; 71 diagnosed at < 21 years. Among survivors diagnosed at < 21 years, 91% reported their diagnosis on entrance forms.

CONCLUSIONS

Through education and optimization of health informatics, college health centers can identify and provide survivor care to this medically vulnerable population.

General practitioner involvement in follow-up of childhood cancer survivors: a systematic review

BACKGROUND

An increasing number of childhood cancer survivors need long-term follow-up care. Different models address this problem, including that of follow-up by general practitioners (GP). We describe models that involve GPs in follow-up for childhood cancer survivors, their advantages and disadvantages, clinics that employ these models, and the elements essential to high-quality, GP-led follow-up care.

PROCEDURE

We searched four databases (PubMed [including Medline], Embase, Cochrane, and CINAHL) without language restrictions.

RESULTS

We found 26 publications, which explicitly mentioned GP-led follow-up. Two models were commonly described: GP-only, and shared care between GP and pediatric oncology or late effects clinic. The shared care model appears to have advantages over GP-only follow-up. We found four clinics using models of GP-led follow-up, described in five papers. We identified well-organized transition, treatment summary, survivorship care plan, education of GPs and guidelines as necessary components of successful follow-up.

CONCLUSION

Scarcity of literature necessitated a review rather than a meta-analysis. More research on the outcomes of GP-led care is necessary to confirm the model for follow-up of childhood cancer survivors in the long term. However, with the necessary elements in place, the model of GP-led follow-up, and shared care in particular, holds promise.

Do childhood cancer survivors with physical performance limitations reach healthy activity levels?

BACKGROUND

The extent to which physical performance limitations affect the ability of childhood cancer survivors to reach healthy activity levels is unknown. Therefore this study aims to describe the effect of different types of limitations on activity levels in survivors.

PROCEDURE

Within the Swiss Childhood Cancer Survivor Study we sent a questionnaire to all survivors (≥16 years) registered in the Swiss Childhood Cancer Registry, who survived >5 years and were diagnosed 1976-2005 aged <16 years. We measured healthy activity levels using international guidelines and assessed different kinds of performance limitations (visual impairment, weight and endurance problems, cardiorespiratory, musculoskeletal, and neurological problems, pain and fatigue syndromes).

RESULTS

The sample included 1,560 survivors (75% response rate), of whom 209 (13.5%) reported they have performance limitations. Forty-two percent of survivors with limitations reached healthy activity levels, compared to 57% of survivors without limitations. Least active were survivors with vision impairments (25% active), weight and endurance problems (27.3%), cardiorespiratory problems (36.4%), and musculoskeletal problems (43.1%). After adjusting for socio-demographic variables and type of cancer, we found that survivors with limitations were 1.4 (95%CI 1.0-2.0; P = 0.047) times more likely to be inactive.

CONCLUSIONS

Although many survivors with physical performance limitations maintain healthy activity levels, there is room for improvement. Adapted and targeted physical activity counseling for survivors with performance limitations might help them to raise level of activity and pursue a healthy lifestyle.

Second cancers after childhood cancer--GPs beware!

BACKGROUND

One of the long-term effects in childhood cancer survivors (CCS) is the development of second cancers. In a cohort of CCS, this study describes how second cancers were presented, the way they were diagnosed, and the knowledge CCS had about their increased risk to develop a second cancer.

PATIENTS AND METHODS

Selected participants were all adult five-year CCS (n = 1275) who were treated at the University Medical Center Groningen since 1965. Of these, 84 (6.6%) had developed a second cancer, of which 27 had died. The 57 survivors were asked to participate in a telephone interview.

RESULTS

Of the 57 CCS, 35 (61%) participated. Together they had developed 45 second cancers. Most participants (97%) were seen at the long-term follow-up clinic. Of all second cancers, 89% caused symptoms. Of all second cancers, the majority (56%) were first presented at the general practitioner's (GP's) office and 20% at follow-up testing. Of these CCS, only 28% were aware of their increased risk of developing a second cancer.

CONCLUSIONS

It is important to inform CCS continuously regarding their increased risk, as a relatively small percentage are aware of this. Since most of these patients first reported their symptoms to the GP, all GPs should be aware of this increased risk, in particular because this concerns cancer at a younger age than normally expected. A survivor care plan might be an effective way of communication with both CCS and GPs.
