Abstract
A total of $275 million has been launched to The Cancer Genome Atlas Project for genomic mapping of more than 20 types of cancers. The major challenge is to develop high throughput and cost-effective techniques for human genome sequencing. We developed a targeted exome sequencing technology to routinely determine human exome sequence. As a proof-of-concept, we chose a unique patient, who underwent three high mortalities cancers, i.e., breast, gallbladder and lung cancers, to reveal the genetic cause of high-cancer-susceptibility. Total 24,545 SNPs were detected. 10,868 (44.27%) SNPs were within coding regions, and 1,077 (4.38%) located in the UTRs. 3367 genes were hit by 4480 non-sysnonymous mutations in CDS with truncation of 30 proteins; and 10 mutations occurred at the splice sites that would generate different protein isoforms. Substitutions or premature terminations occurred in 132 proteins encoded by cancer-associated genes. CARD8 was completely loss; ANAPC1 was pre-translationally terminated from the transcripts of one allele. On the Ras-MAPK pathway, 18 genes were homozygously mutated. 15 growth factors/cytokines and their receptors, 9 transcription factors, 6 proteins on WNT signaling pathway, and 16 cell surface and extracellular proteins may be dysfunctioned. Exome sequencing made it possible for individualized cancer therapy.

Abstract
Although important advances have been made in curing childhood cancer in the last several decades, long-term survivors face considerable morbidity and mortality because of late effects from their initial anticancer therapy. By 30 years after treatment, the cumulative mortality from treatment-related medical illness actually exceeds that of mortality from cancer recurrence. Cardiovascular disease, in particular, is a leading threat to the well-being of adult survivors of childhood cancers. Unfortunately, the mechanisms of these late cardiac effects are understudied and poorly understood. This article reviews cardiotoxicity associated with 2 major anticancer regimens used in treating childhood cancer patients: anthracycline treatment and radiation therapy. The known pathophysiology and clinical cardiac risk factors that further predispose these patients to late-onset cardiac events are discussed. Basic and translational research is urgently needed to clarify pathophysiologic mechanisms of late cardiac effects and to develop therapies to improve both long-term survival and quality of life of adults cured of pediatric cancers.

Abstract
Adequate nutrition during cancer plays a decisive role in several clinical outcome measures, such as treatment response, quality of life, and cost of care. However, the importance of nutrition in children and young adults with malignancies is still an underestimated topic within pediatric oncology. The importance of our work is to reinforce and indicate that malnutrition in children with cancer should not be accepted at any stage of the disease or tolerated as an inevitable process. Unique to our manuscript is the close collaboration, the exchange of knowledge and expertise between pediatric oncologists and a nutritional specialist, as well as the comprehension of the mechanisms during cancer cachexia and malnutrition. We provide a critical review of the current state of research and new knowledge related to nutritional management in childhood cancer.

Abstract
The contribution of specific cancer therapies, comorbid medical conditions, and host factors to mortality risk after pediatric Hodgkin lymphoma (HL) is unclear. We assessed leading morbidities, overall and cause-specific mortality, and mortality risks among 2742 survivors of HL in the Childhood Cancer Survivor Study, a multi-institutional retrospective cohort study of survivors diagnosed from 1970 to 1986. Excess absolute risk for leading causes of death and cumulative incidence and standardized incidence ratios of key medical morbidities were calculated. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of risks for overall and cause-specific mortality. Substantial excess absolute risk of mortality per 10,000 person-years was identified: overall 95.5; death due to HL 38.3, second malignant neoplasms 23.9, and cardiovascular disease 13.1. Risks for overall mortality included radiation dose ≥ 3000 rad ( ≥ 30 Gy; supra-diaphragm: HR, 3.8; 95% CI, 1.1-12.6; infradiaphragm + supradiaphragm: HR, 7.8; 95% CI, 2.4-25.1), exposure to anthracycline (HR, 2.6; 95% CI, 1.6-4.3) or alkylating agents (HR, 1.7; 95% CI, 1.2-2.5), non-breast second malignant neoplasm (HR, 2.6; 95% CI 1.4-5.1), or a serious cardiovascular condition (HR, 4.4; 95% CI 2.7-7.3). Excess mortality from second neoplasms and cardiovascular disease vary by sex and persist > 20 years of follow-up in childhood HL survivors.

Abstract
Treatments for breast cancer produce a host of side effects, which can become debilitating. Some cancer treatment-related side effects occur in up to 90% of patients during treatment and can persist for months or years after treatment has ended. As the number of breast cancer survivors steadily increases, the need for cancer control intervention research to alleviate side effects also grows. This review provides a general overview of recent clinical research studies of selected topics in the areas of symptom management for breast cancer with a focus on cognitive difficulties, fatigue, cardiotoxicity, bone loss, insomnia, and cancer pain. We review both pharmacological and behavioral intervention clinical research studies, conducted with breast cancer patients and survivors. Additionally, clinical perspectives on symptom management and recommendations for areas of needed research are provided.

Abstract
BACKGROUND Survivors of childhood acute lymphoblastic leukemia (ALL) are vulnerable to exaggeration of the aging process including decreased bone mineral density (BMD). As little is known about their dietary or nutrient intake that may affect their long-term bone health, we examined nutrient intake in long-term survivors of childhood ALL. PROCEDURE Survivors (n = 164) of childhood ALL who had completed treatment for at least 5 years and were in continuous remission, completed a 110-item food questionnaire that reflected dietary intake over the previous year. The analyzed cohort comprised 34 females and 38 males younger than 19 years and 45 females and 47 males at least 19 years. Reported nutrient intake and food selection were compared with age-specific Recommended Dietary Allowance and USDA Pyramid Food Guide. Body mass index was compared to the general US population, adjusted for age, gender, Tanner stage and race. RESULTS Less than 30% of participants met recommended dietary intakes for vitamin D, calcium, potassium, or magnesium regardless of age. Mean daily caloric intake was 2,204 kcal (51% from carbohydrates) for younger and 2,160 kcal (49% from carbohydrates) for older participants. Energy intake from sweets was 70% higher than recommended. Participants < 19 years were less likely to have a healthy weight (odds ratio 0.48, 95% CI 0.30-0.79); > 19 years more likely to be overweight (odds ratio 1.95, 95% CI 1.11-3.32, P < 0.002). CONCLUSIONS Survivors of childhood ALL need careful dietary intervention to optimize long-term health.

Abstract
Although increasing numbers of studies have examined late effects in survivors, there is a paucity of long-term outcome studies in their siblings, so-called sibling survivors. Our aim was to provide a review of publications relevant to survivorship and its impact on the long-term psychosocial health of sibling survivors using a family systems framework. A review of publications identified 19 articles that reported findings suggesting that aspects of psychosocial health may be impaired in sibling survivors. Baseline functioning of sibling survivors may be altered at the start of survivorship secondary to apprehension, memories, and emotions. New demands are placed on sibling survivors, including doubts, questions, and worries due to survivorship. Survivor disfigurement may also place demands on sibling survivors associated with behavioral problems. Associated with these changes, there may be alterations in adaptation, including depression, somatic complaints, and posttraumatic stress symptoms. Sibling survivors may also report health risk behaviors and decreased vitality. Identification of the impact of survivorship on the long-term psychosocial health of sibling survivors may help ensure the long-term psychosocial health of all survivors.

Abstract
BACKGROUND Adult childhood cancer survivors report high levels of unemployment, although it is unknown whether this is because of health or employability limitations. OBJECTIVES We examined 2 employment outcomes from 2003 in the Childhood Cancer Survivor Study (CCSS): (1) health-related unemployment and (2) unemployed but seeking work. We compared survivors with a nearest-age CCSS sibling cohort and examined demographic and treatment-related risk groups for each outcome. METHODS We studied 6339 survivors and 1967 siblings ≥25 years of age excluding those unemployed by choice. Multivariable generalized linear models evaluated whether survivors were more likely to be unemployed than siblings and whether certain survivors were at a higher risk for unemployment. RESULTS Survivors (10.4%) reported health-related unemployment more often than siblings (1.8%; Relative Risk [RR], 6.07; 95% Confidence Interval [CI], 4.32-8.53). Survivors (5.7%) were more likely to report being unemployed but seeking work than siblings (2.7%; RR, 1.90; 95% CI, 1.43-2.54). Health-related unemployment was more common in female survivors than males (Odds Ratio [OR], 1.73; 95% CI, 1.43-2.08). Cranial radiotherapy doses ≥25 Gy were associated with higher odds of unemployment (health-related: OR, 3.47; 95% CI, 2.54-4.74; seeking work: OR, 1.77; 95% CI, 1.15-2.71). Unemployed survivors reported higher levels of poor physical functioning than employed survivors, and had lower education and income and were more likely to be publicly insured than unemployed siblings. CONCLUSIONS Childhood cancer survivors have higher levels of unemployment because of health or being between jobs. High-risk survivors may need vocational assistance.

Abstract
Because of remarkable progress in therapy, long-term survival is expected for 80% of children and adolescents diagnosed with cancer. Infertility remains one of the most common and life-altering complications experienced by adults treated for cancer during childhood. Surgery, radiation, or chemotherapy that negatively affects any component of the hypothalamic-pituitary-gonadal axis may compromise reproductive outcomes in childhood cancer survivors. The risk of infertility is generally related to the tissues or organs involved in cancer and the specific type, dose, and combination of cytotoxic therapy. In addition to anticancer therapy, age at treatment, sex, and likely genetic factors influence the risk of permanent infertility. When possible, contemporary protocols limit cumulative doses of cytotoxic therapy in an effort to optimize reproductive potential. If sterilizing therapy is required for cancer control, then fertility preservation measures should be explored before initiation of therapy. For childhood cancer survivors who maintain fertility, health risks to offspring resulting from their cancer treatment are major concerns. Radiation affecting ovarian and uterine function has been linked to pregnancy complications, including spontaneous abortion, preterm labor, fetal malposition, and low birth weight. The risk of congenital malformations, genetic disorders, and cancer appears to be low, with the exception of cancer risk in offspring born to survivors with germline cancer-predisposing mutations. This review summarizes research about cancer treatment factors affecting fertility and pregnancy outcomes of childhood cancer survivors. The data presented should facilitate the delivery of preventive counseling and age- and sex-appropriate interventions to optimize reproductive outcomes in childhood cancer survivors.

Abstract
Chronic renal impairment in children with cancer may be caused by the malignant process itself or result from adverse effects of treatment including cytotoxic drugs, radiotherapy, surgery or supportive treatment. Although severe renal chronic disease is uncommon, occurring in only 0.8% of long-term survivors of childhood cancer, 1.9% of all cases of established renal failure are due to malignancy and 0.8% to drug nephrotoxicity. The relative risk of severe renal chronic disease (compared with siblings) is 8.1, and that of renal failure or the need for dialysis is 8.9. The cytotoxic drugs most likely to cause important chronic nephrotoxicity are ifosfamide and cisplatin, both of which are used widely in many solid tumors and may cause chronic glomerular and/or renal tubular toxicity in 30–60% of treated children. Significant renal toxicity is less frequent with other chemotherapeutic drugs, but may result from treatment with carboplatin, methotrexate and nitrosoureas. Other cytotoxic drugs occasionally cause specific patterns of glomerular or tubular toxicity in children. Partial or unilateral nephrectomy leads to hypertrophy and hyperfiltration of the remaining renal tissue, and may result in microalbuminuria, hypertension and in rare cases, chronic renal impairment. Radiotherapy to a field including renal tissue may cause late onset chronic renal damage, manifest by hematuria, proteinuria, hypertension and anemia, sometimes progressing to chronic renal failure. Chronic nephrotoxicity is also common in survivors of hemopoietic stem cell transplantation, and is often multifactorial with contributions from prior chemotherapy, total body irradiation, immunosuppressive drugs and transplant complications, such as infection or hemorrhage. Patients at risk of renal damage should be monitored regularly with a defined surveillance protocol to enable timely management. General measures often employed to prevent or reduce nephrotoxicity include the use of intravenous hydration during drug administration and avoidance of known risk factors, such as high drug doses. Although numerous potentially nephroprotective drugs have been suggested and investigated, none have yet been introduced into clinical use in children due to the lack of proven efficacy. Improved understanding of the pathogenesis of nephrotoxicity is necessary to reduce the frequency and severity of this potentially serious complication of treatment in children with cancer.

Abstract
In the last four decades, advances in therapies for primary cancers have improved overall survival for childhood cancer. Currently, almost 80% of children will survive beyond 5 years from diagnosis of their primary malignancy. These improved outcomes have resulted in a growing population of childhood cancer survivors. Radiation therapy, while an essential component of primary treatment for many childhood malignancies, has been associated with risk of long-term adverse outcomes. The Childhood Cancer Survivor Study (CCSS), a retrospective cohort of over 14,000 survivors of childhood cancer diagnosed between 1970 and 1986, has been an important resource to quantify associations between radiation therapy and risk of long-term adverse health and quality of life outcomes. Radiation therapy has been associated with increased risk for late mortality, development of second neoplasms, obesity, and pulmonary, cardiac and thyroid dysfunction as well as an increased overall risk for chronic health conditions. Importantly, the CCSS has provided more precise estimates for a number of dose-response relationships, including those for radiation therapy and development of subsequent malignant neoplasms of the central nervous system, thyroid and breast. Ongoing study of childhood cancer survivors is needed to establish long-term risks and to evaluate the impact of newer techniques such as conformal radiation therapy or proton-beam therapy.

Abstract
BACKGROUND Since 1980, childhood cancer cases have been registered in Spain in the National Registry of Childhood Cancer (based on hospital cases) and since 1990, five autonomous regions have had a population based registry. There is no specific registry of childhood cancer in Castilla y Leon. OBJECTIVES Our aim was to estimate the childhood cancer incidence in the autonomous region of Castilla y Leon and to assess the usefulness of the computerised diagnosis of hospital discharges as a source of data in a potential autonomous region population based registry. METHODS We included patients younger than 15 years old who were diagnosed, for the first time, of cancer during the years 2003-2007. The information collected was obtained through the Minimum Basic Data Set (MBDS) of the public hospitals in the autonomous region of Castilla y Leon. RESULTS In this period of 5 years (2003-2007), 220 cases of childhood cancer had been reported. The most frequent cancer detected was leukaemia (28.6%) followed by the central nervous system tumours (19.5%) and lymphoma (15.9%). The overall rate of childhood cancer incidence was 152.8 cases per million children. The diagnostics codes did not allow tumours to be classified by their histological type in 74 cases (33.6%). CONCLUSIONS The overall incidence by diagnostic groups of childhood cancer in the autonomous region of Castilla y Leon was similar to those reported by other national and international registries. In a Cancer registry the MBDS could be useful as a data source in the capture of new cases, but in a high percentage of cases it does not allow tumours to be classified by their histological type.

Abstract
BACKGROUND The occurrence of subsequent neoplasms has direct impact on the quantity and quality of life in cancer survivors. We have expanded our analysis of these events in the Childhood Cancer Survivor Study (CCSS) to better understand the occurrence of these events as the survivor population ages. METHODS The incidence of and risk for subsequent neoplasms occurring 5 years or more after the childhood cancer diagnosis were determined among 14,359 5-year survivors in the CCSS who were treated from 1970 through 1986 and who were at a median age of 30 years (range = 5-56 years) for this analysis. At 30 years after childhood cancer diagnosis, we calculated cumulative incidence at 30 years of subsequent neoplasms and calculated standardized incidence ratios (SIRs), excess absolute risks (EARs) for invasive second malignant neoplasms, and relative risks for subsequent neoplasms by use of multivariable Poisson regression. RESULTS Among 14,359 5-year survivors, 1402 subsequently developed 2703 neoplasms. Cumulative incidence at 30 years after the childhood cancer diagnosis was 20.5% (95% confidence interval [CI] = 19.1% to 21.8%) for all subsequent neoplasms, 7.9% (95% CI = 7.2% to 8.5%) for second malignant neoplasms (excluding nonmelanoma skin cancer), 9.1% (95% CI = 8.1% to 10.1%) for nonmelanoma skin cancer, and 3.1% (95% CI = 2.5% to 3.8%) for meningioma. Excess risk was evident for all primary diagnoses (EAR = 2.6 per 1000 person-years, 95% CI = 2.4 to 2.9 per 1000 person-years; SIR = 6.0, 95% CI = 5.5 to 6.4), with the highest being for Hodgkin lymphoma (SIR = 8.7, 95% CI = 7.7 to 9.8) and Ewing sarcoma (SIR = 8.5, 95% CI = 6.2 to 11.7). In the Poisson multivariable analysis, female sex, older age at diagnosis, earlier treatment era, diagnosis of Hodgkin lymphoma, and treatment with radiation therapy were associated with increased risk of subsequent neoplasm. CONCLUSIONS As childhood cancer survivors progress through adulthood, risk of subsequent neoplasms increases. Patients surviving Hodgkin lymphoma are at greatest risk. There is no evidence of risk reduction with increasing duration of follow-up.

Abstract
In the last four decades, advances in neurosurgical technique, delivery of radiation therapy (RT), supportive care, and use of chemotherapy have improved 5-year survival for children with central nervous system (CNS) malignancies. Currently, in the United States 74% of children will become 5-year survivors of their primary CNS malignancy. This improved outcome has resulted in a new and growing population of childhood cancer survivors. Surgery, RT and chemotherapy, while essential components of primary treatment for most childhood CNS malignancies, have also been associated with risk of long-term morbidity and late mortality. The Childhood Cancer Survivor Study, a retrospective cohort of over 14,000 survivors of childhood cancer diagnosed between 1970 and 1986, has been an important resource for quantification of associations between these therapeutic modalities and risk of long-term adverse health and quality of life outcomes. CNS malignancy survivors are at significant risk for late mortality, development of second neoplasms, as well as increased risk for multiple endocrinopathies and adverse neurologic health conditions. Importantly, the CCSS has identified a number of dose-response relationships between RT and development of subsequent malignant neoplasms of the central nervous system, abnormal timing of menarche and neurocognitive function. Ongoing study of childhood cancer survivors is needed to establish long-term risks and evaluate impact of newer techniques such as conformal RT or proton beam delivery that limit RT exposure and may reduce long-term effects.

Abstract
To examine the late effects and health-related quality of life among childhood cancer survivors (CCS) after stem cell transplantation (SCT), we performed a cross-sectional survey using self-rating questionnaires. The subjects were divided into 3 groups: SCT-treated CCS, CCS treated without SCT, and the general population who matched for age, gender, residential area, and work status with the CCS. We analyzed the questionnaires of 185 CCS and 1,000 control participants. The median ages of CCS at diagnosis and survey were 8 and 22 years, respectively. The mean final heights of male and female participants were significantly lower for SCT-treated CCS than for CCS treated without SCT and the controls. Among the SCT-treated CCS, >40% were underweight (BMI < 18.5). Late effects were observed in 78% of SCT-treated CCS versus 45% of CCS treated without SCT. Multivariate analysis revealed that >15 years' duration after therapy completion (OR 2.95; p = 0.014), solid tumors (4.31; p = 0.040), radiotherapy (2.82; p = 0.009), recurrence (4.22; p = 0.017), and SCT (3.39; p = 0.014) were significant risk factors for late effects. Subjective symptoms were significantly frequent in SCT-treated CCS. Physical dysfunction, psychological stress, and social adaptation problems were observed in >70% of SCT-treated CCS.

Abstract
One of the prices paid for chemo- and radiotherapy of cancer in children is damage to the vulnerable and developing healthy tissues of the body. Such damage can exist clinically or subclinically and can become apparent during active antineoplastic treatment or during remission decades later. Furthermore, effects of the tumor itself can significantly impact the physiologic state of the child. The anesthesiologist who cares for children with cancer or for survivors of childhood cancer should understand what effects cancer and its therapy can have on various organ systems. In part two of this three-part review, we review the anesthetic issues associated with childhood cancer. Specifically, this review presents a systems-based approach to the impact from both tumor and its treatment in children, followed by a discussion of the relevant anesthetic considerations.

Abstract
The anesthesiologist who cares for children with cancer or for survivors of childhood cancer should possess a basic understanding of cancer treatment. While this is an ever-changing field, a basic knowledge of chemotherapeutic drugs, radiation therapy, and the toxicities of each is necessary to prepare a safe anesthetic plan. Such an understanding also assists the anesthesiologist as the perioperative specialist for these children in consultation with the surgeon and oncologist. This article, which is the first of a three-part review series, will review current principles of cancer therapy and the general mechanisms of toxicity to the child. Although this article is not intended to comprehensively review the fundamentals of chemotherapy and radiation therapy, the consequences of anticancer therapy that impact perioperative care and decision making are presented for the anesthesiologist.

Abstract
PURPOSE Cancer in children may profoundly affect parents' personal relationships in terms of psychological stress and an increased care burden. This could hypothetically elevate divorce rates. Few studies on divorce occurrence exist, so the effect of childhood cancers on parental divorce rates was explored. PATIENTS AND METHODS Data on the entire Norwegian married population, age 17 to 69 years, with children age 0 to 20 years in 1974 to 2001 (N = 977,928 couples) were retrieved from the Cancer Registry, the Central Population Register, the Directorate of Taxes, and population censuses. Divorce rates for 4,590 couples who were parenting a child with cancer were compared with those of otherwise similar couples by discrete-time hazard regression models. Results Cancer in a child was not associated with an increased risk of parental divorce overall. An increased divorce rate was observed with Wilms tumor (odds ratio [OR], 1.52) but not with any of the other common childhood cancers. The child's age at diagnosis, time elapsed from diagnosis, and death from cancer did not influence divorce rates significantly. Increased divorce rates were observed for couples in whom the mothers had an education greater than high school level (OR, 1.16); the risk was particularly high shortly after diagnosis, for CNS cancers and Wilms tumors, for couples with children 0 to 9 years of age at diagnosis, and after a child's death. CONCLUSION This large, registry-based study shows that cancer in children is not associated with an increased parental divorce rate, except with Wilms tumors. Couples in whom the wife is highly educated appear to face increased divorce rates after a child's cancer, and this may warrant additional study.

Abstract
PURPOSE Little is known about physicians' attitudes and knowledge regarding the health care needs of childhood cancer survivors (CCS). We sought to obtain pediatric cancer physicians' self-reported attitudes and knowledge regarding this population. METHODS A mailed survey was sent to 1,159 pediatric oncologists in the United States. Results A total of 655 surveys were returned (ie, 57% response rate). Median age of respondents was 47 years (range, 31 to 82 years); 57% were men. Respondents practiced for a median 14 years (range, 1 to 50 years) and reported seeing a median of 21 patients per week (range, 0 to 250 patients per week). When comfort levels in caring for CCS were described (ie, 1 = very uncomfortable; 7 = very comfortable), respondents were most comfortable with survivors < or = 21 years (mean +/- standard deviation, 6.2 +/- 1.3 level), were less comfortable (5.0 +/- 1.5 level) with those older than 21 years but less than 30 years old, and were uncomfortable with CCS > or = 30 years (2.9 +/- 1.7 level). In response to a clinical vignette of a 29-year-old woman treated with mantle radiation for Hodgkin's lymphoma at 16 years of age, and on the basis of available guidelines, 34% of respondents did not appropriately recommend yearly breast cancer surveillance; 43% of respondents did not appropriately recommend cardiac surveillance; and 24% of respondents did not appropriately recommend yearly thyroid surveillance. Those with greater self-reported familiarity with available long-term follow-up (LTFU) guidelines (odds ratio [OR], 1.33; 95% CI, 1.15 to 1.54) and with receipt of training in the care of CCS (OR, 1.73; 95% CI, 1.18 to 2.52) were more likely to have answered all three questions correctly. CONCLUSION Pediatric oncologists express a range of preferences with regard to LTFU of CCS. Many appear unfamiliar with LTFU surveillance guidelines.

Abstract
Physical performance limitations are one of the potential long-term consequences following diagnosis and treatment for childhood cancer. The purpose of this review is to describe the risk factors for and the participation restrictions that result from physical performance limitations among childhood cancer survivors who participated in the Childhood Cancer Survivor Study (CCSS). Articles previously published from the CCSS cohort related to physical performance limitations were reviewed and the results summarized. Our review showed that physical performance limitations are prevalent among childhood cancer survivors and may increase as they age. Host-based risk factors for physical disability include an original diagnosis of bone tumor, brain tumor, or Hodgkin's disease; female sex; and an income less than $20,000 per year. Treatment-based risk factors include radiation and treatment with a combination of alkylating agents and anthracyclines. Musculoskeletal, neurologic, cardiac, pulmonary, sensory, and endocrine organ system dysfunction also increase the risk of developing a physical performance limitation. In summary, monitoring of physical performance limitations in an aging cohort of childhood cancer survivors is important and will help determine the impact of physical performance limitations on morbidity, mortality, and caregiver burden. In addition, in developing restorative and preventive interventions for childhood cancer survivors, we must take into account the special needs of survivors with physical disability to optimize their health and enhance participation in daily living activities.

Abstract
Abstract
Evidence for integrative therapies (IT) in children with hematological malignancies is slowly evolving. The ideal model of integrative pediatric oncology would offer IT modalities that are deemed safe and effective in conjunction with effective conventional medical treatments. Because of potential interactions, herbs and other dietary supplements should be used with caution, especially during active therapy. Health and wellness should be the emphasis, with IT therapies supporting health promotion and key disease prevention strategies for childhood cancer survivors. All uses, responses, and effects of IT therapies should be carefully documented. A desire to use IT therapies may be an effort to become an active participant in the healing process. Health care providers should encourage, not discourage, this partnership.
