Abstract
BACKGROUND Changes in bone age and tooth development are late side effects of cancer therapy and can be identified by imaging examination. AIM To evaluate the late effects of antineoplastic treatment on bone age and dental development in childhood cancer survivors. DESIGN This is a retrospective case-control study on paediatric cancer survivors of both sexes who underwent antineoplastic treatment with 5-15 years of survival. Carpal radiographs were assessed for bone age and growth curve, and panoramic radiographs were used to evaluate dental development and alterations. Carpal radiographs were analyzed using the Greulich and Pyle inspection method, and the Martins and Sakima method was used to analyze the growth curve. All tests were applied with a confidence level of 95%. RESULTS The study and control groups comprised 28 and 56 patients, respectively. There was no significant difference in bone age and growth curve between the study and control groups. Nonetheless, when sex was compared to chronological and bone ages, there was a significant difference in bone age (p = 0.019) and an underestimation in both groups and sexes in the Greulich and Pyle method. As to late dental effects, dental agenesia, microdontia, gyroversion, and unerupted teeth were found. Dental shape alterations mainly involve the root region. CONCLUSION Close multidisciplinary collaboration is necessary during the follow-up period of young patients who have survived cancer.

Structural and Functional Brain Imaging in Long-Term Survivors of Childhood Acute Lymphoblastic Leukemia Treated With Chemotherapy: A Systematic Review. JNCI Cancer Spectr 2021; 5:pkab069.

Abstract
Background The effect of chemotherapy on brain development in long-term survivors of pediatric acute lymphoblastic leukemia (ALL) was systematically reviewed. Methods A systematic search of Pubmed, Scopus, and PsycINFO databases was conducted to identify articles published between January 2000 and February 2020 that implemented magnetic resonance imaging to assess brain structure and function in pediatric ALL survivors (diagnosed younger than 21 years of age). The review included articles that were published on children diagnosed with ALL between 0 and 21 years of age and treated with chemotherapy-only protocols. Articles meeting the inclusion criteria described survivors on average of 5 years or more from diagnosis and were peer-reviewed articles and original studies. Results The search yielded 1975 articles with 23 articles meeting inclusion criteria. The review revealed that survivors had statistically significant alterations in brain anatomy, most commonly a smaller hippocampus and impaired microstructural white matter integrity in frontal brain regions. Survivors also had impaired brain function including lower brain network efficiency and altered resting state connectivity. Survivors also displayed widespread reductions in brain activation (ie, frontal, temporal, parietal brain regions) during cognitive tasks. Conclusion Although the neurotoxic effects of cancer treatment are reduced in the absence of cranial radiation, survivors treated on chemotherapy-only protocols still display long-term alterations in brain structure and function, which contribute to lifelong neurocognitive late effects.

Abstract
Acute lymphoblastic leukemia (ALL), currently the most common pediatric leukemia, has a high curability rate of up to 90%. Endocrine disorders are highly prevalent in children with ALL, and skeletal morbidity is a major issue induced by multiple factors associated with ALL. Leukemia itself is a predominant risk factor for decreased bone formation, and major bone destruction occurs secondary to chemotherapeutic agents. Glucocorticoids are cornerstone drugs used throughout the course of ALL treatment that exert significant effects on demineralization and osteoclastogenesis. After completion of treatment, ALL survivors are prone to multiple hormone deficiencies that eventually affect bone mineral accrual. Dual-energy X-ray absorptiometry, the most widely used method of measuring bone mineral density, is used to determine the presence of childhood osteoporosis and vertebral fracture. Supplementation with calcium and vitamin D, administration of pyrophosphate analogues, and promotion of mobility and exercise are effective options to prevent further bone resorption and fracture incidence. This review focuses on addressing bone morbidity after pediatric ALL treatment and provides an overview of bone pathology based on skeletal outcomes to increase awareness among pediatric hemato-oncologists and endocrinologists.

Abstract
BACKGROUND An increase in survival rates of childhood cancer is associated with long-term health issues in survivors. METHODS We conducted a systematic review and meta-analysis comparing health status-related endpoints in childhood cancer survivors (CCS) versus controls. RESULTS Eighty-six studies (n = 98,480 participants, 62% CCS) were included in the review. Of these, 73 studies (n = 96,550, 63% CCS) could be meta-analyzed. CCS showed a lower left ventricular ejection and fractional shortening (SMD=-0.59 and -0.55, respectively, both p < 0.01 [n=1,824 and 1,880]), a lower HDL-cholesterol concentration (SMD=-0.48, p<0.001, n=1,378) and a higher waist-to-hip ratio (SMD=0.61, p < 0.01, n=229) than their healthy peers. No significant differences were found for the remaining endpoints. CONCLUSIONS CCS is associated with a lower left ventricular function and HDL-cholesterol level, and a higher waist-to-hip ratio than healthy controls. These findings support the need to closely monitor the cardiometabolic health status of CCS and to implement preventive lifestyle interventions for this population.

Abstract
The number of patients surviving ≥5 years after initial cancer diagnosis has significantly increased during the last decades due to considerable improvements in the treatment of many cancer entities. A negative consequence of this is that the emergence of long-term sequelae and endocrine disorders account for a high proportion of these. These late effects can occur decades after cancer treatment and affect up to 50% of childhood cancer survivors. Multiple predisposing factors for endocrine late effects have been identified, including radiation, sex, and age at the time of diagnosis. A systematic literature search has been conducted using the PubMed database to offer a detailed overview of the spectrum of late endocrine disorders following oncological treatment. Most data are based on late effects of treatment in former childhood cancer patients for whom specific guidelines and recommendations already exist, whereas current knowledge concerning late effects in adult-onset cancer survivors is much less clear. Endocrine sequelae of cancer therapy include functional alterations in hypothalamic-pituitary, thyroid, parathyroid, adrenal, and gonadal regulation as well as bone and metabolic complications. Surgery, radiotherapy, chemotherapy, and immunotherapy all contribute to these sequelae. Following irradiation, endocrine organs such as the thyroid are also at risk for subsequent malignancies. Although diagnosis and management of functional and neoplastic long-term consequences of cancer therapy are comparable to other causes of endocrine disorders, cancer survivors need individually structured follow-up care in specialized surveillance centers to improve care for this rapidly growing group of patients.

Abstract
Objective Bone mineral density (BMD) in children may be negatively affected by acute lymphoblastic leukemia (ALL) or its treatment protocol. The aim of our study was to evaluate bone health by measuring BMD after ALL treatment. Materials and Methods The age, anthropometric measurements, and lumbar spine BMDs were recorded in 39 pediatric survivors of ALL, with no history of relapse, secondary malignancy, or transplantation. The lumbar spine BMD was measured by dual energy x-ray absorptiometry. The BMD risk factors, pubertal status, age at diagnosis, risk category, the time interval from the completion of the chemotherapy, and cranial radiotherapy were investigated. Serum calcium, phosphate, alkaline phosphates, magnesium, parathormone, and 25-hydroxy vitamin D levels were determined. Results The mean BMD value was calculated as 0.668±0.176 g/cm2. Osteopenia and osteoporosis were detected in nine patients (23.1%) and three patients (7.7%), respectively, according to previously published data of healthy age- and sex-related Turkish children's BMD values. The mean age at diagnosis of patients with ALL, having the Z-score above -1 was lower than in patients having bone defect (Z score <-1). Conclusion Early detection and intervention strategies to optimize bone health are essential in pediatric patients with ALL.

Abstract
Background Decrease in bone mineral density, osteoporosis development, bone toxicity and resulting insufficiency fractures as late effect of radiotherapy are not well known. Osteoporosis development related to radiotherapy has not been investigated properly and insufficiency fractures are rarely reported for vertebral bones. Methods Ninety-seven patients with gastric adenocarcinoma were evaluated for adjuvant treatment after surgery. While 73 out of 97 patients treated with adjuvant chemoradiotherapy comprised the study group, 24 out of 97 patients with early stage disease without need of adjuvant treatment comprised the control group. Bone mineral densities (BMD) of lumbar spine and femoral neck were measured by dual energy x-ray absorptiometry after surgery, and one year later in both groups. Results There was statistically significant decline in BMDs after one year in each group itself, however the decline in BMDs of the patients in the irradiated group was more pronounced when compared with the patients in the control group; p values were 0.02 for the decline in BMDs of lumbar spine, and 0.01 for femoral neck respectively. Insufficiency fractures were observed only in the irradiated patients (7 out of 73 patients) with a cumulative incidence of 9.6%. Conclusions Abdominal irradiation as in the adjuvant treatment of gastric cancer results in decrease in BMD and osteoporosis. Insufficiency fracture risk in the radiation exposed vertabral bones is increased. Calcium and vitamin D replacement and other measures for prevention of osteoporosis and insufficiency fractures should be considered after abdominal irradiation.

Abstract
IMPORTANCE Bone accrual during youth is critical to establish sufficient strength for lifelong skeletal health. Children with cancer may develop low bone mineral density (BMD) any time before or after diagnosis. OBJECTIVE To evaluate the ability of low-magnitude, high-frequency mechanical stimulation to enhance BMD among childhood cancer survivors. DESIGN, SETTING, AND PARTICIPANTS Double-blind randomized clinical trial conducted at St Jude Children's Research Hospital from June 1, 2010, to January 22, 2013, using cancer survivors, ages 7 to 17 years, who were previously treated at St Jude Children's Research Hospital, were in remission, and at least 5 years from diagnosis, with whole-body or lumbar spine BMD z scores of -1.0 or lower. Participants were randomized (stratified by sex and Tanner stage) to either a placebo device or low-magnitude, high-frequency mechanical stimulation device, which was used at home. INTERVENTIONS Placebo or low-magnitude, high-frequency mechanical stimulation (0.3 g; 32-37 Hz) for 2 sessions lasting 10 minutes each, 7 days per week for 1 year. All participants were prescribed daily cholecalciferol (vitamin D) and calcium. MAIN OUTCOMES AND MEASURES Changes in areal and volumetric BMD and bone biomarkers were compared by analysis of variance, adjusted for strata. RESULTS Of the 65 participants, 32 were randomized to the intervention group (mean [SD] age was 13.6 [3.7] years, 18 [56.2%] were male, and 27 [84.4%] were white), and 33 were randomized to the placebo group (mean [SD] age was 13.6 [2.9] years, 17 [51.5%] were male, and 26 [78.8%] were white). Forty-eight participants completed the trial, 22 in the intervention group and 26 in the placebo group with median adherence of 70.1% for intervention and 63.7% for placebo groups. With intention-to-treat analysis, mean (SD) whole-body BMD z score by dual x-ray absorptiometry improved by 0.25 (0.78) in the intervention (n = 22), but decreased by -0.19 (0.79) in the placebo group (n = 26, P = .05). Circulating osteocalcin at 12 months correlated with change in total body BMD (r = 0.35, P = .02). Tibial trabecular bone among participants completing 70% or more of the prescribed sessions increased by a mean of 11.2% (95% CI, 5.2 to 17.2%) compared with those completing less than 70% who decreased by a mean of -1.3% (95% CI, -7.3 to 4.7%; P = .02). Change in circulating receptor activator of nuclear factor κ-B ligand was higher in the intervention than in the placebo group (0.06 [0.16] vs -0.04 [0.17] pmol/L) (P = .04). CONCLUSIONS AND RELEVANCE Pediatric cancer survivors with low BMD may benefit from low-magnitude, high-frequency mechanical stimulation as a novel and safe intervention to optimize peak bone mass during youth, alone or in conjunction with other therapies.

Abstract
Endocrine complications are frequently observed in childhood cancer survivors (CCS). One of two CCS will experience at least one endocrine complication during the course of his/her lifespan, most commonly as a late-effect of cancer treatments, especially radiotherapy and alkylating agent chemotherapy. Endocrine late-effects include impairments of the hypothalamus/pituitary, thyroid and gonads, as well as decreased bone mineral density and metabolic derangements leading to obesity and/or diabetes mellitus. A systematic approach where CCS are screened for endocrine late-effects based on their cancer history and treatment exposures may improve health outcomes by allowing the early diagnosis and treatment of these complications.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) and its treatment are often implicated in adversely affecting bone health. Conflicting reports in the literature and a paucity of studies from the developing world prompted us to study bone mineral density (BMD) in childhood ALL survivors. METHODS BMD lumbar spine (LS) and whole body (WB) were evaluated, using dual energy x-ray absorptiometry in 65 pediatric ALL survivors who had been off-therapy for at least 2 years. The control group constituted of 50 age- and sex-matched healthy siblings. Kernel density plots were used to compare BMD among cases and controls. The disease-, treatment-, hormone- and lifestyle-related factors likely to modulate BMD were analyzed using the Mann-Whitney U test and Student's t-test. RESULTS At a median of 4.3 years (range, 2-14.8 years) since cessation of therapy, height-adjusted (HA) mean BMD Z-scores of LS (-0.67 ± 1.11, -0.607 ± 1.05, P = 0.759) and WB (-0.842 ± 0.92, -0.513 ± 0.97, P = 0.627) were comparable among the cases and controls. Disease, treatment (chemotherapy, cranial radiotherapy) and endocrine factors did not predict low BMD. However, survivors with calcium intake <800 mg/day (WB, P = 0.018) and hypovitaminosis D (≤25 nmol/L) had lower BMD values (HA-WB, P = 0.046) than the controls. A significant proportion of survivors were overweight or obese and had higher BMD Z-scores (HA-LS, P = 0.003; HA-WB, P = 0.028). CONCLUSION BMD Z-scores were similar among ALL survivors and controls. It was reassuring that there was no detrimental impact of the disease or its treatment on BMD. Future studies are required to determine the best possible ways to target the modifiable risk factors (diet, vitamin D) to optimize bone health.

Abstract
Premenopausal women who develop ovarian failure after receiving chemotherapy are at a higher risk of rapid bone loss. Pharmacists have successfully implemented osteoporosis screening programmes in the general population and thus, assessment of breast cancer survivors for ovarian failure and osteopenia could represent a novel focus for oncology pharmacists. Therefore, we conducted a retrospective chart review to determine the adequacy of ovarian failure and osteoporosis assessment and management in premenopausal breast cancer survivors. Methods and results. The charts of 20 women diagnosed with early stage breast cancer treated with cyclophosphamide over a 4.5-year timespan were included. Their median age was 36.7 years (range 29.8-41). The median cyclophosphamide cumulative dose was 9 g/m2 (range 2.4-14.45), with a median duration of follow-up being 4.62 years. The assessment of ovarian failure mainly occurred by documenting menstrual periods, which has been questioned as a reliable method for assessing ovarian failure. Menses stopped while or shortly after receiving chemotherapy in 11 women. Prior to and during cyclophosphamide administration, osteoporosis screening or counselling was not documented for any patient. After completion of chemotherapy administration, eight patients were counselled regarding osteoporosis and seven women were screened for osteoporosis with a dual X-ray absorptimetry (DXA) scan. Five women had DXA scans indicative of osteopenia according to World Health Organization guidelines. Conclusions. Improvements are needed in the documentation and potentially also the management of ovarian failure and osteoporosis in premenopausal breast cancer survivors receiving cyclophosphamide-based regimens. This represents a potential opportunity for pharmacists to manage long-term chemotherapy toxicity.

BACKGROUND We sought to improve lumbar spine bone mineral density (LS-BMD) in long-term survivors of childhood acute lymphoblastic leukemia (ALL) using calcium and cholecalciferol supplementation. PROCEDURE This double-blind, placebo-controlled trial randomized 275 participants (median age, 17 [9-36.1] years) with age- and gender-specific LS-BMD Z-scores <0 to receive nutritional counseling with supplementation of 1,000 mg/day calcium and 800 International Unit cholecalciferol or placebo for 2 years. The primary outcome was change in LS-BMD assessed by quantitative computerized tomography (QCT) at 24 months. Linear regression models were employed to identify the baseline risk factors for low LS-BMD and to compare LS-BMD outcomes. RESULTS Pre-randomization LS-BMD below the mean was associated with male gender (P = 0.0024), White race (P = 0.0003), lower body mass index (P < 0.0001), and cumulative glucocorticoid doses of ≥ 5,000 mg (P = 0.0012). One hundred eighty-eight (68%) participants completed the study; 77% adhered to the intervention. Mean LS-BMD change did not differ between survivors randomized to supplements (0.33 ± 0.57) or placebo (0.28 ± 0.56). Participants aged 9-13 years and those 22-35 years had the greatest mean increases in LS-BMD (0.50 ± 0.66 and 0.37 ± 0.23, respectively). Vitamin D insufficiency (serum 25[OH]D <30 ng/ml) found in 296 (75%), was not associated with LS-BMD outcomes (P = 0.78). CONCLUSION Cholecalciferol and calcium supplementation provides no added benefit to nutritional counseling for improving LS-BMD among adolescent and young adult survivors of ALL (93% of whom had LS-BMD Z-scores above the mean at study entry).

Abstract
The growth hormone deficiency (GHD) syndrome is associated with several metabolic abnormalities and it has been postulated that the increased cardiovascular disease (CVD) morbidity and mortality in GHD patients may be related to the missing metabolic effects of GH. Many CVD risk factors show improvements after GH therapy. Reduced bone mineral density (BMD) has been recorded both in patients with isolated GHD and in those with multiple pituitary deficiencies, indicating that GHD per se is responsible for the low BMD in both types of patients. These matters are, however, more complicated, as hypopituitary patients with GHD may have different phenotypes due to differences in underlying diagnoses. These phenotypes may not be clear-cut in individual patients. Moreover, patients may transit between different phenotypes over time due to extension of the pathology in the pituitary and/or the consequences of the treatment (surgery and/or radiotherapy). Three different phenotypes of hypopituitary patients will be discussed, with a focus on CVD risk and bone health: (1) patients with isolated GHD, e.g. due to prophylactic cranial radiotherapy for lymphoblastic leukaemia in childhood; (2) patients with GHD and multiple hormone deficiencies due to pituitary macroadenomas treated by surgery; (3) patients with GHD caused by craniopharyngiomas with multiple hormone deficiencies and hypothalamic involvement, where hypothalamic damage frequently dominates the positive metabolic effects of GH therapy. These phenotypes illustrate the differential impact of various pituitary pathologies on the phenotype of patients with GHD.

Abstract
Although substantial increases in survival rates among children diagnosed with cancer have been observed in recent decades, survivors are at risk of developing therapy-related chronic health conditions. Among children and adolescents treated for cancer, acquisition of peak bone mass may be compromised by cancer therapies, nutritional deficiencies, and reduced physical activity. Accordingly, failure to accrue optimal bone mass during childhood may place survivors at increased risk for deficits in bone density and fracture in later life. Current recommendations for the treatment of bone density decrements among cancer survivors include dietary counseling and supplementation to ensure adequate calcium and vitamin D intake. Few strategies exist to prevent or treat bone loss. Moving forward, studies characterizing the trajectory of changes in bone density over time will facilitate the development of interventions and novel therapies aimed at minimizing bone loss among survivors of childhood cancer.

Abstract
PURPOSE Children with acute lymphoblastic leukemia (ALL) are at risk for impaired bone accrual. This peripheral quantitative computed tomography study assessed changes in bone mineral density (BMD) and structure after completion of ALL treatment. METHODS Fifty ALL participants, ages 5-22 yr, were enrolled within 2 yr (median 0.8 yr) after completing ALL therapy. Tibia peripheral quantitative computed tomography scans were performed at enrollment and 12 months later. Age-, sex-, and race-specific Z-scores for trabecular BMD (TrabBMD), cortical BMD (CortBMD), and cortical area (CortArea) were generated based on more than 650 reference participants. Multivariable linear regression models examined determinants of changes in Z-scores. RESULTS At enrollment, mean TrabBMD (-1.03±1.34) and CortBMD (-0.84±1.05) Z-scores were low (both P<0.001) compared with reference participants. TrabBMD and CortBMD Z-scores increased to -0.58±1.41 and -0.51±0.91 over 1 yr, respectively (both P<0.001). Changes in cortical outcomes varied according to the interval since completion of therapy. Among those enrolled less than 6 months after therapy, CortArea Z-scores increased and CortBMD Z-scores decreased (both P<0.01). Among those enrolled 6 months or more after therapy, CortArea Z-scores did not change and CortBMD Z-scores increased (P<0.01). Changes in CortArea and CortBMD Z-scores were inversely associated (r=-0.32, P<0.001). Cumulative glucocorticoid exposure, leukemia risk status, and antimetabolite chemotherapy were not associated with outcomes. CONCLUSION TrabBMD was low after completion of ALL therapy and improved significantly. Early increases in cortical dimensions were associated with declines in CortBMD; however, participants further from ALL therapy demonstrated stable cortical dimensions and increases in CortBMD, potentially reflecting the time necessary to mineralize newly formed bone.

Abstract
SUMMARY We measured bone mineral densities in 28 intracranial germ cell tumor long-term survivors. There was the high prevalence of osteoporosis and osteopenia, 25.0% and 42.9%, respectively, and three additional risk factors, male sex, a low lean mass, and adult growth hormone replacement, were identified. INTRODUCTION Intracranial germ cell tumor long-term survivors (iGCTLS) have many risk factors for osteoporosis, including irradiation from cancer therapy and multiple hormone deficiencies. However, no study of bone mineral density (BMD) has been conducted in iGCTLS because these tumors are rare. The aims of this study were to evaluate the prevalence of osteoporosis and to identify risk factors associated with reduced bone mass in iGCTLS. METHODS We evaluated BMD and body composition of 28 iGCTLS (10.9 ± 5.2 years after cancer treatment; 13 males) using dual-energy X-ray absorptiometry. To determine risk factors, we analyzed the medical history, including the nature of the tumor, treatment modality, endocrine status, hormone replacement therapy, lifestyle, and biochemical parameters. RESULTS Twenty-five percent of iGCTLS were diagnosed with osteoporosis and 42.9% with osteopenia. Most males (92.3%) had low BMD. Lean mass (LM) was positively correlated with BMD in all regions of interest, and the starting age of adult growth hormone (GH) replacement was negatively correlated with the BMD Z-score at the femur neck. In logistic regression analysis, male sex and low LM were related to low BMD. CONCLUSIONS The iGCTLS had a high prevalence of low BMD. We found that male sex, low LM, and delayed start of adult GH replacement were risk factors for osteoporosis. Therefore, the BMD of all iGCTLS should be evaluated, and if it is low, proper management should be started early.

Abstract
Children requiring allogeneic hematopoietic stem cell transplantation (alloHSCT) have multiple risk factors for impaired bone accrual. The impact of alloHSCT on volumetric bone mineral density (vBMD) and cortical structure has not been addressed. Tibia peripheral quantitative computed tomography (pQCT) scans were obtained in 55 alloHSCT recipients, ages 5 to 26 years, a median of 7 (range, 3-16) years after alloHSCT. pQCT outcomes were converted to sex- and race- specific Z-scores relative to age based on reference data in >700 concurrent healthy participants. Cortical section modulus (Zp; a summary measure of cortical bone structure and strength), and muscle and fat area Z-scores were further adjusted for tibia length for age Z-scores. AlloHSCT survivors had lower height Z-scores (-1.21 ± 1.25 versus 0.23 ± 0.92; p < 0.001), versus reference participants; BMI Z-scores did not differ. AlloHSCT survivors had lower trabecular vBMD (-1.05; 95% confidence interval [CI], -1.33 to -0.78; p < 0.001), cortical Zp (-0.63; 95% CI, -0.91 to -0.35; p < 0.001), and muscle (-1.01; 95% CI, -1.30 to -0.72; p < 0.001) Z-scores and greater fat (0.82; 95% CI, 0.54-1.11; p < 0.001) Z-scores, versus reference participants. Adjustment for muscle deficits eliminated Zp deficits in alloHSCT. Total body irradiation (TBI) was associated with lower trabecular vBMD (-1.30 ± 1.40 versus -0.49 ± 0.88; p = 0.01) and muscle (-1.34 ± 1.42 versus -0.34 ± 0.87; p < 0.01) Z-scores. Growth hormone deficiency (GHD) was associated with lower Zp Z-scores (-1.64 ± 2.47 versus -0.28 ± 1.24; p = 0.05); however, muscle differences were not significant (-1.69 ± 1.84 versus -0.78 ± 1.01; p = 0.09). History of graft versus host disease was not associated with pQCT outcomes. In summary, alloHSCT was associated with significant deficits in trabecular vBMD, cortical geometry, and muscle area years after transplantation. TBI and GHD were significant risk factors for musculoskeletal deficits. Future studies are needed to determine the metabolic and fracture implications of these deficits, and to identify therapies to improve bone accrual following alloHSCT during childhood.

Abstract
Femoral and lumbar bone mineral densities (BMDs) were measured in 159 adults enrolled in the Leucémies de l'Enfant et de l'Adolescent program, a French prospective multicentric cohort of childhood leukemia survivors. BMDs were expressed as Z-scores, and multivariate linear regression analyses were used to construct association models with potential risk factors. Mean age at evaluation and follow-up was 23 and 14.7 years, respectively. In the whole cohort, mean femoral Z-score was -0.19 ± 0.08. Two factors were associated with lower femoral BMD transplantation (-0.49 ± 0.15 vs -0.04 ± 0.10 in the chemotherapy group; P = .006) and female sex (-0.34 ± 0.10 vs -0.03 ± 0.13; P = .03). Among patients who received a transplant, the only significant risk factor was hypogonadism (-0.88 ± 0.16 vs -0.10 ± 0.23; P = .04). A slight reduction in lumbar BMD (mean Z-score, -0.37 ± 0.08) was detected in the whole cohort without difference between the transplantation and chemotherapy groups. Among patients who received a transplant, younger age at transplantation was correlated with a low lumbar BMD (P = .03). We conclude that adults who had received only chemotherapy for childhood leukemia have a slight reduction in their lumbar BMD and a normal femoral BMD. Patients who received a transplant with gonadal deficiency have a reduced femoral BMD which might increase the fracture risk later in life.

Abstract
OBJECTIVE Bone mineral density (BMD) in survivors of acute lymphoblastic leukaemia (ALL) seems to vary with time, type of treatments and GH status. We aimed to evaluate BMD in ALL patients with GH deficiency (GHD), with and without GH therapy. DESIGN Case-control study. METHODS We examined 44 (21 women) GHD patients (median 25 years) treated with cranial radiotherapy (18-24 Gy) and chemotherapy and matched population controls for BMD with dual-energy X-ray absorptiometry. For 5 and 8 years, two subgroups with (0.5 mg/day) (n=16) and without GH therapy (n=13) and matched controls were followed respectively. RESULTS At baseline, no significant differences in BMD or Z-scores at femoral neck and L2-L4 were recorded (all P>0.3). After another 8 years with GHD, the Z-scores at femoral neck had significantly decreased compared with baseline (0.0 to -0.5; P<0.03) and became lower at the femoral neck (P=0.05), and at L2-L4 (P<0.03), compared with controls. After 5 years of GH therapy, only female ALL patients had a significantly lower femoral neck Z-scores (P=0.03). The female ALL patients reached an IGF1 level of -0.7 s.d. and male patients reached the level of +0.05 s.d. CONCLUSIONS On average, 25 years after diagnosis, GH-deficient ALL patients experienced a significant decrease in Z-scores at femoral neck, and if Z-scores continue to decrease, there could be a premature risk for osteoporosis. GH therapy was not shown to have a clear beneficial effect on BMD. Whether higher GH doses, particularly in women, will improve Z-scores needs further investigation.

Abstract
BACKGROUND Neuroblastoma is the second most common extracranial malignant tumor of childhood and the most common solid tumor of infancy which is characterized by bone metastasis. Previous reports on bone mineral density (BMD) in patients with leukemia and solid malignancies concentrate on long-term survivors and on the effect of chemotherapeutic agents and irradiation. Also, evaluation of BMD in neuroblastoma was reported in few studies which were conducted upon adult survivors of childhood cancer. Previous studies on both acute leukemia and lymphoma patients suggested that the disease process itself played a role in decrease BMD. METHODS We evaluated 27 patients with newly diagnosed neuroblastoma for both lumbar (L2-L4) BMD and total BMD using dual energy X-ray absorptiometery (DXA) scan to highlight the effect of neuroblastoma as a disease process on BMD as this disease characterized by bone metastasis. RESULTS Three out of the 27 patients showed low bone mass in both lumbar and total BMD studies. CONCLUSION Low bone mass may occur in early disease process of neuroblastoma and it is important to consider BMD assessment during the early course of the disease as well as the long-term survivors as a part of the patient screening in suspected cases.

Abstract
The ultrastructure of murine femoral lamellar bone and the effect of electron irradiation (200 kV) on collagen and mineral features were investigated using in situ high resolution transmission electron microscopy (HRTEM). Bands of collagen fibrils were mostly aligned parallel to the long axis of the bones, with some bands of fibrils inclined in longitudinal sections. The similarity of the ultrastructure between the longitudinal and transverse sections supports the rotated plywood structure of the lamellar bone. The collagen fibrils appeared damaged and the mineral crystals were coarsened after electron irradiation. Continuous diffraction rings became spotty and the contrast between rings and the background became sharper, further suggesting coarsening of apatite crystals and increased crystallinity after irradiation. No new phases were observed after irradiation. Both the damage to collagen and coarsening of apatite crystals can deteriorate the strength and integrity of bone, and may provide insight into fracture in patients who have undergone radiation therapy.

Abstract
BACKGROUND We hypothesized that pediatric Hodgkin lymphoma (HL) survivors would have bone mineral density (BMD) deficits compared to their peers because of osteotoxic chemotherapy during the time of greatest BMD accretion. METHODS We retrospectively reviewed records of HL survivors returning for follow-up between 1990 and 2002. Of the 133 eligible survivors, 109 who underwent quantitative computed tomography (QCT) comprised the study group. QCT-determined BMD Z-scores were correlated with patient characteristics and therapeutic exposures by Wilcoxon rank sum or Chi-square tests. Logistic regression models were used to explore risk factors for diminished BMD. RESULTS The study cohort was half male (50.5%) and 85.3% reported their race as white. Participants were representative of all survivors potentially eligible for study, except that more study participants were female, had hypothyroidism, and had received cyclophosphamide. Median age at diagnosis was 15.1 years (range, 3.1-20.7 years); median time between diagnosis and QCT was 7.5 years (range, 5.0-12.4 years). The proportion of HL survivors with BMD below the mean did not significantly differ from the general population (P = 0.503). However, those with BMD -1.5 SD and BMD -2.0 SD or lower (14.7% and 7.3%, respectively) exceeded that in the general population (6.7% and 2.3%, respectively; P < 0.001 for both degrees of severity). Males, diagnosed at 14 years or older, were at 6.5 times higher risk than females (OR 95% CI: 1.24-34.14; P = 0.027) for BMD deficits. CONCLUSIONS Overall, pediatric HL survivors had negligible BMD deficits. Male gender was associated with an increased risk of developing BMD deficits.

Abstract
BACKGROUND The purpose of the current study was to determine the prevalence of low bone mineral density (BMD) (ie, osteopenia) and identify factors associated with low BMD in young adult survivors of childhood acute lymphoblastic leukemia (ALL). METHODS Dual energy x-ray absorptiometry was used to evaluate BMD in 74 randomly selected, long-term childhood ALL survivors initially treated in Minneapolis/St. Paul, Minnesota. Growth hormone (GH)-releasing hormone-arginine stimulation testing was conducted to evaluate peak GH level, and insulin-like growth factor I (IGF-I) and other markers of endocrine functioning were also evaluated in relation to BMD. RESULTS The mean age at the time of interview was 30 years, and the mean time since diagnosis was 24 years. Low BMD (Z-score, < or = -1) was present in 24% of subjects, including 1 with osteoporosis. Low BMD was substantially more prevalent in men than in women and was strongly associated with short height. The mean height Z-score for those with low BMD was -1.44, compared with a height Z-score of -0.39 (P < .01) for those with normal BMD. GH insufficiency, low IGF-I Z-score, and current smoking were also suggestive risk factors for low BMD. CONCLUSIONS In this long-term follow-up study of childhood ALL survivors, low BMD was found to be more prevalent than expected based on population normative data, specifically in men. The health consequences of early-onset BMD problems in childhood ALL survivors need to be carefully monitored.

Abstract
BACKGROUND Abnormalities in bone mineral density (BMD) occur in children treated for acute lymphoblastic leukemia (ALL). However, BMD estimates have been performed using varied instruments, reference data, and interpretations. This exploratory cross sectional study to evaluate bone mass in children with ALL, uses an algorithm that serially adjusts for variables known to affect pediatric bone measures by dual energy X-ray absorptiometry (DXA), based on models developed in 1,218 healthy children and adolescents. PROCEDURE Anthropometry, DXA scans, and factors with possible influence on bone mass were evaluated in 21 ALL patients receiving chemotherapy and 20 in the follow-up phase. Main outcome was treatment group differences in Z-scores for total body bone mineral content (BMC), bone area (Area), and areal BMD (aBMD). RESULTS Mean Z-scores for the entire study population for BMC, Area, and aBMD were significantly less than zero. Among possible contributing factors, only calcium intake was a significant co-variate. Comparison between treatment groups showed that least-square mean Z-scores for patients on-therapy for at least 12 months were significantly lower than those off therapy for at least 12 months (P: 0.0008-0.044), except for BMC at last step of the algorithm (adjusted for sex, age, ethnicity, height, weight, and bone area). CONCLUSIONS Evaluation of total body DXA by this algorithm is consistent with better general bone status in those off-therapy. However, in this small exploratory study, the lack of significant difference between Z-scores for fully adjusted BMC in on- versus off-therapy groups suggests possible risk of low peak bone mass. Additional longitudinal evaluation is warranted.

Abstract
BACKGROUND Skeletal bone accretion occurs throughout childhood. The integrity of this process can influence future adult bone health and the risk of osteoporosis. Although surveillance of children who are at risk of poor bone accretion is important, the most appropriate method to monitor childhood bone health has not been established. Previous investigators have proposed using bone age (BA) rather than chronological age (CA) when interpreting bone mineral density (BMD) values in children. OBJECTIVE To investigate the value of BA assessment for BMD measurement in a cohort of children at risk of poor accretion. MATERIALS AND METHODS A cohort of 163 children with brain tumors who completed both a BMD assessment (quantitative computed tomography, QCT) and who had a BA within a 6-month interval were identified. The difference in BMD Z-scores determined by CA and BA was determined. The impact of salient clinical features was assessed. RESULTS No significant difference between CA and BA Z-scores was detected in the overall cohort (P = 0.056). However, the scores in 18 children (all boys between the ages of 11 years and 15 years) were statistically determined to be outliers from the values in the rest of the cohort. CONCLUSION Interpretation of BMD with BA measurement might be appropriate and affect treatment decisions in peripubertal males.

Abstract
The aim of this work was to study the effect of disease process on bone mass and calcium homeo-stasis in children with malignant lymphoma at diagnosis, 3 months after starting chemotherapy, and after 1 year. Evaluation of lumber vertebrae (L2-L4) bone mineral density using dual-energy X-ray absorptiometry and calcium homeostasis parameters and bone turnover biochemical markers (serum osteocalcin and urinary deoxypyridinoline) had been assayed in twenty lymphoma patients at presentation and after treatment. Low bone mass for chronological age was observed in 4 patients (20%) at diagnosis and persisted after 3 months and 1 year. Parathyroid hormone level demonstrated no differences between children with lymphoma at different stages of therapy and controls, while 25(OH) D(3) was significantly lower in lymphoma patients at different stages of therapy as compared to controls (p < .001). Osteocalcin was significantly lower in lymphoma patients at different stages of therapy. Deoxypyridinoline showed only significant higher values after 3 months of therapy compared to controls (p = .01). In conclusion, low bone mass was observed in children with lymphoma and is related to decreased osteoblastic activity and decreased mineralization of bone.

Abstract
Advances in hematopoietic stem cell transplantation (HSCT) have resulted in broader indications for this therapeutic modality in both malignant diseases and nonmalignant conditions. This article focuses on the late endocrine abnormalities that are most commonly observed following successful HSCT, with a special emphasis on pediatric HSCT recipients, for whom long-term follow-up data are increasingly available.

Abstract
BACKGROUND Several factors, including the use of antiepileptic drugs, glucocorticoids, anticoagulants, chemotherapy, radiation therapy, and hemiplegia-associated osteopenia, render patients with brain tumor susceptible to bone disease. METHODS The authors review the pathophysiology of these factors and their impact upon bone integrity. RESULTS Steps that can be taken to minimize or eliminate bone morbidity including measurement of bone mineral density at treatment onset, adequate calcium intake, vitamins D and K supplementation, adequate sunlight exposure, weight-bearing exercises, fall prevention, avoidance of antiepileptic drugs linked to osteopenia, and judicious use and choice of glucocorticoids and anticoagulants are suggested. CONCLUSIONS Medical management of osteoporosis related to brain tumor treatment with bisphosphonates, teriparitide, and calcitonin is beneficial, as is kyphoplasty for symptomatic vertebral compression fractures.

Abstract
The attainment of a satisfactory peak bone mass, which is accomplished largely by the end of adolescence, is the best protection against excessive bone mineral loss in late adulthood. Factors that influence this process include age, race, sex, body size, pubertal status, diet, physical activity, and other lifestyle elements. Cancer and its treatment in children and teenagers adversely impact bone mineralization. In particular, chemotherapy (especially glucocorticosteroids and methotrexate) and cranial irradiation (apparently by reducing growth hormone secretion and by causing hypogonadotropic hypogonadism) interfere with normal bone turnover. Resorption often exceeds formation, resulting in net bone mineral loss and providing a rational basis for the use of antiresorptive drugs. Such osteopenia may be symptomatic, with pain and abnormal gait, and increases the risk of fractures several fold. The disorder is compounded by reduced physical activity, so programs to reduce this deficit are of measurable benefit. All of those engaged in the care of children and adolescents with cancer have an opportunity to improve the bone health of these young people and to limit their risk of developing osteoporosis and fragility fractures in adult life.

Abstract
Reduced bone mineral density (BMD) occurs frequently in children after hematopoietic cell transplantation (HCT), but therapy for this complication is undefined. To determine the impact of bisphosphonate therapy on reduced BMD after HCT, we compared baseline and follow-up dual energy X-ray absorptiometry (DEXA) scans of 48 patients (controls) who received calcium and vitamin D to 18 patients who also received bisphosphonate therapy. Among the controls, median annualized increase in standardized BMD (sBMD) was 10% (range, -26% to +41%), but the deviation of sBMD from normal, as indicated by the Z-score, did not improve from baseline, -2.46 (range: -5.15 to -1.16) compared to follow-up, -2.79 (range: -5.76 to +0.07). For the bisphosphonate-treated patients, the median annualized increase in sBMD was 33% (range 3% to 147%, P = .0002) and the median Z-score improved from -3.57 (range: -5.13 to -0.86) at baseline, to -1.80 (-4.89 to +0.47) at follow-up (P = .06). The annualized median change in BMD Z-scores per year was +0.12 (-2.28 to +4.24) among the controls and +1.43 (-0.29 to +3.72) for the bisphosphonate group (P = .0002). The greatest improvement in BMD was observed in children who received therapy with bisphosphonates.

Abstract
BACKGROUND Osteopenia has been reported in children surviving acute lymphoblastic leukaemia, apparently as consequence of therapy. Few studies have been published on bone mineral density (BMD) evaluation in children surviving from brain tumours. The endocrine system in these patients is frequently affected as consequence of therapeutic interventions such as cranial irradiation and anti-neoplastic agents: growth hormone deficiency is the most common adverse sequel. The pathogenesis of osteopenia in brain cancer survivors is multi-factorial but still uncertain. OBJECTIVE The aim of this study is to examine bone mass in 12 brain cancer survivors and its relationship with their hormonal status. RESULTS AND DISCUSSION We observed that most of the patients had a BMD that was lower than normal in both the lumbar column and in the femoral neck. Bone mass loss was higher in the lumbar region rather than in the femoral neck, due to spinal radiation therapy and to the effect of hormonal deficiencies. Particularly hypogonadism, but also multiple hormonal deficiencies, are associated with lower BMD values. Experience in clinical care of these patients suggests the importance of periodic evaluations of BMD, especially in those with secondary hormone deficiencies. Moreover, the periodic assessment of the hypothalamus-pituitary function is essential for an early diagnosis of hormonal insufficiency, primarily hypogonadism, to precociously detect bone mineral loss and to prevent pathological fractures, thus improving the quality of life.

Abstract
PURPOSE The pathophysiology, frequency, sequelae, diagnosis, and treatment of cancer-treatment-induced bone loss (CTIBL) are discussed. SUMMARY CTIBL is a long-term complication associated with cancer therapies that can directly or indirectly affect bone metabolism. Although CTIBL can occur in any patient receiving a cancer therapy known to cause bone loss, CTIBL is most common in patients with breast or prostate cancer who receive chemotherapy, hormone therapy, or surgical castration, as these can cause hypogonadism and induce bone loss. CTIBL causes bone fragility and an increased susceptibility to fractures; therefore, prevention, early diagnosis, and treatment of CTIBL are essential to decrease the risk of fracture. Bone loss occurs more rapidly and tends to be more severe in patients with CTIBL compared with those with normal age-related bone loss. Fractures of the hip, vertebra, and wrist are the fractures most commonly associated with bone loss. CTIBL is diagnosed by measuring bone mass using bone densitometry. Treatment of CTIBL consists of changing diet and lifestyle such as optimizing calcium and vitamin D intake, exercising, modifying behaviors known to increase the risk of CTIBL and pharmacologic therapy with hormone replacement therapy (HRT), selective estrogen-receptor modifiers (SERMs), calcitonin, or a bisphosphonate. CONCLUSION Early identification and treatment of CTIBL are essential to prevent fractures. Patients should be instructed to optimize calcium and vitamin D intake, exercise regularly, and modify lifestyle behaviors known to cause bone loss. Patients with CTIBL should be treated with an oral or i.v. bisphosphonate; SERMs or HRT may be an option in some patients if contraindications do not exist.

Abstract
Alendronate (ALN) and other bisphosphonates have been used successfully in pediatric patients with osteopenia secondary to connective tissue diseases. Loss of growth in height has not been reported, but concerns remain regarding the effect of these potent antiresorptive agents when used in children and adolescents. High-dose methotrexate (MTX) and other chemotherapy drugs have been implicated in osteoporosis and a high fracture incidence in survivors of childhood cancers and are also associated with osteopenia in adult animals. The effect of high dose MTX on bone density during rapid skeletal growth, however, has not been widely studied, nor has the potentially therapeutic effect of bisphosphonates in this setting. We examined the effects of ALN and MTX administration, alone and in combination, on bone density, morphology, mechanical strength, and longitudinal growth in normal growing rats. Sprague-Dawley rats were given ALN once weekly (0.3 mg/kg) from 5 to 11 weeks of age, with and without a course of methotrexate (MTX) given daily in weeks 1 and 3 (0.75 mg/kg/day). Twenty-four animals were randomly divided into four groups: Control (vehicle), ALN alone, ALN + MTX, and MTX alone. After 6 weeks, the femora, tibiae, and lumbar spine were studied by dual-energy X-ray absorptiometry, peripheral quantitative computed tomography, mechanical strength testing, microradiography, light microscopy, and by determination of ash weights and bone lengths. ALN treatment increased bone mineral density (BMD) by 23% to 68%. The largest increases in the femur occurred in the distal third where endochondral bone growth was greatest and included large increases in trabecular bone and total cross-sectional area. ALN + MTX produced similar effects to ALN alone. MTX only reduced BMD by 8% in the vertebrae, but not significantly at other sites. MTX also led to femoral length reductions of 2.9%. The small reductions in BMD due to MTX were overwhelmed by the increases due to ALN, whereas the length loss was unaffected. Transverse density banding corresponding to weekly ALN administrations were clearly evident radiographically throughout the growing skeleton, likely due to decreased resorption and possibly increased mineralization in the bands. ALN or ALN + MTX treatment also led to increases in mechanical strength in the femora. Although MTX administration during growth leads to some BMD reduction, ALN given with MTX eliminates this reduction and in fact bone density and strength increase above control levels.

Abstract
BACKGROUND Osteopenia has been reported in children surviving acute lymphoblastic leukemia and brain tumors, apparently as a consequence of therapy. It has been suggested that cranial irradiation may play a role in the development of this complication. In order to explore that possibility, we examined survivors of brain tumors treated with and without radiation in childhood to investigate associations between radiation, osteopenia, physical activity, health status and overall health-related quality of life (HRQL). PROCEDURE Subjects were survivors of posterior fossa tumors (astrocytoma or medulloblastoma) or optic glioma, < 18 years of age at diagnosis and > 1 year off treatment. Measurements of growth velocity, body composition, bone densitometry, physical activity and HRQL were undertaken. RESULTS Twenty-five (62.5%) of the 40 eligible patients participated in the study. Of the 25 patients, 12 (48%) received radiation therapy (R group) while 13 received no radiation (NR group). Growth hormone (GH) deficiency had been detected in three subjects, one had completed GH therapy while two were still on hormone replacement. The prevalence of osteopenia was 44% in the entire group, and 67% versus 27% in the R and NR groups. Florid osteoporosis was present in 20% of the entire group, more than 40% of the R group but none of the NR group. A significant correlation (P < 0.01) was observed between overall HRQL and Z scores of bone mineral density (BMD) of the lumbar spine. Pain and ambulation/mobility utility scores correlated significantly (P < 0.05) with BMD, while levels of physical activity correlated (P < 0.05) with overall HRQL utility scores. CONCLUSIONS This pilot study demonstrates that in survivors of brain tumors treated in childhood, radiation therapy is associated with significant loss of bone mineral. Among these survivors, HRQL is less, pain is more severe and ambulation is more restricted in those with low BMD scores. The reduction in HRQL is reflected in diminished physical activity. A larger multi-center study is needed to confirm these results.

Abstract
BACKGROUND There is little information about factors modulating bone mineral density (BMD) in survivors of childhood acute lymphoblastic leukemia (ALL). PROCEDURE We analyzed data from 57 survivors (26 male, 52 Caucasian) who underwent two serial quantitative computed tomography (QCT) studies of BMD. Using multiple linear regression, we evaluated the association of BMD change with demographic variables, treatment history, hormone therapy, exercise, and tobacco and alcohol use. RESULTS The median age was 3.4 years (range, 0.9-17.4 years) at diagnosis of ALL; the median age at the first QCT (Study I) was 15.0 years (range, 10.6-31.0 years) and at the second QCT (Study II) was 18.2 years (range, 14.2-35.3 years). Mean height increased 4.7 cm and mean weight increased 8.8 kg between Studies I and II. While the mean BMD increased 9.33 mg/cc (P = 0.003), the BMD Z-score increased only slightly (0.21 SD, P = 0.035). Cortical bone density increased significantly (approximately 25.3 mg/cc; P = 0.001), but the ratio of trabecular to cortical BMD decreased significantly (P = 0.045). Factors independently associated with unfavorable BMD changes included older age at diagnosis (P = 0.001), female sex (P = 0.018), and nutritional supplementation (0.032). Alcohol (P = 0.009) was an unfavorable factor in a univariable analysis. CONCLUSIONS Bone mineral accretion during adolescence is attenuated in childhood ALL survivors by a comparative deficit in trabecular versus cortical bone deposition. BMD is influenced favorably by exercise in early adolescence and unfavorably by the use of nutritional supplements and alcohol. These results provide new information about behavioral factors that affect bone accrual in survivors of childhood ALL and warrant definitive evaluation in a larger cohort.

Abstract
PURPOSE/OBJECTIVES To identify factors that predict or modify substance use in childhood cancer survivors and to describe how a risk-counseling intervention reduced young survivors' substance use. DESIGN Secondary analysis of clinical trial data and primary analysis of medical record data. SETTING Outpatient clinic. SAMPLE 149 females and 118 males 12-18 years of age whose cancer had been in remission for at least two years were randomly assigned to intervention (n = 132) and standard care (n = 135) groups. METHODS Self-report questionnaires, abstracted medical record data, confirmatory factor analysis, and structural equation modeling. MAIN RESEARCH VARIABLES Smoking, alcohol consumption, knowledge, risk perceptions, motivation, and worry about cancer and treatment effects. FINDINGS Three factors directly predicted substance use at baseline: being in a higher grade in school (independent of age), feelings of being more susceptible to late effects of cancer therapy, and worrying more about cancer and its treatment. At follow-up a year later, grade in school and worry predicted increased substance use. In addition, a desire to change health behavior, influenced by the intervention and gender, predicted decreased substance use. The mechanism of influence of the intervention was evident: The intervention led to a need to change, which precipitated a desire to change and ultimately resulted in decreased substance use. CONCLUSIONS Young survivors' worries and concerns about their cancer and treatment-related late effects are a new intervention target. Motivation is sensitive to behavioral change interventions and positively affects risk reduction. IMPLICATIONS FOR NURSING Two new intervention strategies to address the impact of survivors' concerns about their cancer and its treatment are implied: (a) Replace substance use with new coping methods to reduce fear and anxiety, and (b) tailor motivation-based interventions to age and gender to communicate graphically and realistically to survivors the personal importance of behavioral change in modifying the risks of late effects.

Abstract
BACKGROUND Dexamethasone is known to have both more potent leukemic activity and is associated with a higher incidence of side effects than prednisolone. In this study, we compared the long-term effects of dexamethasone and prednisolone on bone mineral density (BMD), body composition and growth in long-term survivors of ALL in first complete remission. PROCEDURE Ninety patients (51 male, 49 female; 8.6-38.5 year), treated with either a prednisolone containing protocol (n = 47; n = 19 also with CNS-irradiation) or a dexamethasone containing protocol (n = 43; no cranial irradiation) participated in this cross-sectional single center study. Mean follow-up was 12.7 years (2.0-29.7 years). BMD of lumbar spine and total body, and body composition were expressed as standard deviation scores (SDS) using dual energy X-ray absorptiometry. Bone mineral apparent density of the lumbar spine (BMAD) was calculated to correct for bone size. RESULTS There was no difference in height, height corrected for target height, BMD, or lean body mass between prednisolone and dexamethasone treated patients. Prednisolone treated patients had an increased percentage body fat (SDS +0.46; P < 0.05) and increased body mass index (SDS 0.88; P < 0.01) compared to normal. Dexamethasone treated patients had only an increased body mass index (SDS 0.52; P < 0.05). Height, total body BMD, and lean body mass were lower in patients treated with cranial irradiation as compared to non-irradiated patients, but differences in the latter two disappeared when corrected for height. BMAD was normal after CNS-irradiation. CONCLUSIONS Long term survivors of ALL treated with prednisolone or dexamethasone containing regimens do not differ in height, BMD, or body composition.

Abstract
In the present study the authors evaluated the status of spinal bone mineral density (BMD) using dual-energy X-ray absorptiometry in a group of 31 children with acute lymphoblastic leukemia, treated by ALL-BFM protocols without irradiation, at different phases of their treatment. These patients were studied (1) within 2 months of diagnosis (group 1, n = 17, median time postdiagnosis 17 days), (2) during chemotherapy (group 2, n = 16, median time on treatment 22 months), and (3) shortly after completion of therapy (group 3, n = 10, median time postchemotherapy 13 months). Twelve patients underwent serial measurements in either of the groups they entered (6 patients of group 1 and 6 patients of group 2). The mean cumulative prednisone dose was 0.8, 4.3, and 5 g/m2 in groups 1, 2, and 3, respectively. A gradual decline of BMD from group 1 through group 3 was observed. The mean value of age- and sex-specific BMD z-score was -0.74 (+/-0.32) in group 1, -1.59 (+/-0.24) in group 2, and -2.03 (+/-0.27) in group 3; there was a statistically significant difference between groups 1 and 3 (p = .022). A BMD z-score < -2 was found in 3 (17%), 4 (25%), and 5 (50%) patients of groups 1, 2, and 3, respectively. In conclusion, a high incidence of reduced bone mass was observed during and shortly after treatment. These findings could have significant consequences in long-term survivors.

Abstract
The aim of this work was to study bone turnover markers, calcium homeostasis and bone mineral density (BMD) in children with acute leukemia at diagnosis, after induction chemotherapy, and during maintenance therapy to delineate abnormalities present. After evaluation of L2-L4 BMD using dual-energy X-ray absorptiometry in patients with acute myeloid and lymphoid leukemia at presentation and after treatment, the results were compared to 352 healthy age- and sex-matched Egyptian controls. Calcium homeostasis parameters and bone turnover biochemical markers (serum osteocalcin and urinary deoxypyridinoline) were also assayed and the results were compared to 12 healthy age- and sex-matched controls. Osteopenia was observed at diagnosis and during treatment in patients with acute leukemia. At diagnosis osteopenia was observed in 27 patients (62.8%): 10 (23.3%) had non severe osteopenia and 17 (39.5%) had severe osteopenia. This low BMD persisted in those who were followed up. Parathyroid hormone (PTH) (pg/ml) levels demonstrated non significant differences between children with acute leukemia at different stages of therapy and controls, while, 25 (OH) D3 (ng/ml) was significantly lower in acute leukemia patients at different stages of therapy compared to controls (p<0.001). Osteocalcin (ng/ml) is significantly lower in patients at different stages of the disease compared to controls (p<0.001) but there was no significant difference between patients at different stages of therapy. Deoxy-pyridoline cross links showed non-significant difference between the different types of acute leukemia and with controls. Osteopenia is a significant problem in children with acute leukemia at presentation and after chemotherapy. Osteopenia in acute leukemia appears to be of the low turnover type (decreased osteoblastic activity and decreased bone mineralization).

Abstract
During recent decades, the survival rate after childhood acute lymphoblastic leukemia (ALL) has improved substantially; consequently, the long-term side effects of ALL and its treatment have gained attention, of which osteoporosis is one of the most important. The purpose of the present study was to compare the influence of different treatment protocols that include high-dose methylprednisolone (HDMP) versus conventional-dose prednisolone (CDP) for remission-induction therapy on bone mineral density (BMD) and serum bone turnover markers in survivors of childhood ALL after cessation of chemotherapy. Thirty-six boy and 23 girl survivors, treated for ALL, were cross-sectionally studied, at a mean age of 11.7 years (range 6-19). Group 1 (n = 30) received CDP therapy (prednisolone, 2 mg/kg/day, orally) and group 2 (n = 29) received HDMP therapy (prednol-L, 900-600 mg/m2, orally). All other therapies were similar in both groups. Cranial irradiation was added for high-risk patients as soon as possible after consolidation therapy. We found that mean lumbar spine BMD z score value was -1.75 (0.83) SDS in group 1 and -1.66 (1.21) SDS in group 2. There is no difference between both groups (P = 0.736). The mean BMD z scores of prepubertal and pubertal patients were not significantly different in both groups. Comparison of serum bone turnover parameters of the patients revealed no difference between the two groups. Stepwise regression analysis revealed that lumbar spine BMD z scores was predicted by height SDS and the time past since cessation of therapy, but not age at diagnosis, BMI SDS, cranial radiotherapy, and puberty. Our study results showed that HDMP treatment did not deteriorate the bone mass any more than CDP treatment. These results proved that high-dose steroid therapy over a short period of time in remission-induction treatment would not affect the bone mass any more adversely than would conventional doses approximately 3 years after cessation of chemotherapy.

Abstract
A radioterapia resulta em endocrinopatias, osteoporose, obesidade e seqüelas neurológicas em pacientes tratados por câncer. A deficiência de GH é a complicação mais freqüente no eixo hipotálamo-hipofisário. A freqüência, prazo de surgimento e gravidade da deficiência de GH dependem da dose recebida durante a irradiação craniana, mas idade à radioterapia e fracionamento da dose também são variáveis importantes. Outras anormalidades do eixo hipotálamo-hipofisário são igualmente dose-dependentes. Baixas doses de irradiação induzem puberdade precoce ou avançada, enquanto altas doses provocam deficiência gonadotrópica. Complicações endócrinas secundárias à irradiação periférica, como distúrbios gonadais ou tireoidianos são descritos. Mesmo com secreção normal de GH, o crescimento pode ser comprometido por lesões ósseas após irradiação corporal total ou crânio-espinhal. Resultados melhores sobre a estatura final têm sido obtidos com reposição de GH em associação com o tratamento da puberdade precoce ou avançada. O objetivo desta revisão é a abordagem das seqüelas endócrinas tardias da radioterapia.

Abstract
OBJECTIVES Abnormalities in bone mineral density (BMD), body composition, and bone metabolism have been reported in children who were treated for acute lymphoblastic leukemia (ALL) during and after completion of therapy. However, these studies are cross-sectional, and no longitudinal data are available in a large group of patients after completion of therapy. In the present study, 1-year longitudinal changes in BMD, body composition, and bone metabolism were evaluated in children with ALL during the first 3 years after completion of therapy without cranial irradiation. METHODS BMD of total body (TB; g/cm(2)), areal and apparent volumetric lumbar spine (L2-L4), lean body mass, and percentage of body fat were measured by dual-energy x-ray absorptiometry in 37 children (median age: 7.9 years; range: 4.7-20.6 years) who were treated for ALL at a median age of 3.3 years (range: 1.1-16.6 years), after a median time of 2.2 years after the completion of treatment, and after a 1-year follow-up period. Two control subjects (n = 74) who were matched for gender, age, and pubertal stage were also longitudinally investigated for body composition for 1 year. Usual serum biochemical markers of calcium metabolism and bone turnover were measured in patients during the study period. RESULTS A slight decrease in TB BMD was found after a median time of 2.2 years after the completion of therapy for ALL in childhood. Patients showed a significantly lower median TB BMD when evaluated <1.5 years as compared with those at >or=1.5 years since completion of therapy. At the time of first evaluation, the percentage of body fat mass was significantly higher and patients were physically less active than their matched control subjects. Although, as expected, during the 1 year of follow-up both groups showed an annual increment in their BMD measurements, a significantly higher increase in TB BMD was observed in patients in comparison with control subjects. During this same period, the increase in the percentage of body fat mass was slightly lower in ALL patients as compared with control subjects. At the end of the follow-up year, BMD, body-composition parameters, and physical activity of ALL patients were similar to those observed in matched control subjects. Serum biochemical markers of bone turnover were normal at both evaluations. CONCLUSIONS A significant increase in TB BMD and a tendency to a lesser increase in percentage of body fat mass were observed during the study period in ALL patients as compared with chronological age-, gender-, and pubertal stage-matched control subjects. These findings suggest a positive effect of long-term completion therapy and increase in physical activity on BMD, body composition, and bone metabolism in patients who have been treated for ALL.

Abstract
The past 3 decades have seen tremendous improvements in the survival of children diagnosed with cancer, with the 5-year survival rate approaching 80%. This improvement in survival has resulted in a growing population of childhood cancer survivors. Use of cancer therapy at an early age can produce complications that may not become apparent until years later. Approximately two thirds of the survivors of childhood cancer experience at least one late effect and about one fourth experience a late effect that is severe or life-threatening, although psychosocial issues in survivors and family members are often underestimated and may be more prevalent. Long-term complications in childhood cancer survivors, such as impairment in growth and development, neurocognitive dysfunction, cardiopulmonary compromise, endocrine dysfunction, renal impairment, gastrointestinal dysfunction, musculoskeletal sequelae, and subsequent malignancies, are related not only to the specific therapy used but also may be determined by individual host characteristics. We review the known late effects in survivors of childhood in order to suggest reasonable starting points for the evaluation of specific long-term problems in this unique but growing population.

Abstract
To investigate the hypothesis that survivors of pediatric solid cancer have low bone mineral density, a cross-sectional study was done of subjects who had received treatment for pediatric solid tumors before 16 years of age and were less than 40 years old at follow-up. Excluded were subjects treated for acute lymphoblastic leukemia or those who had received cranial irradiation, total body radiation, or nonautologous bone marrow transplant. The study group consisted of 38 subjects, with the most common diagnoses being lymphoma (n = 17), sarcoma (n = 8), Wilms tumor (n = 5), and neuroblastoma (n = 4). Median age was 22 years (range 12-32). Time from diagnosis of underlying cancer averaged 12.6 years (range 5.5-20.3). Using criteria of osteopenia (Z-score < or = -1.0 and > -2.0) and osteoporosis (Z-score < or = -2.0) for any one or more areas including total body, lumbar spine, total hip, or femoral neck density, 13 of the 38 subjects (34%) had osteopenia or osteoporosis. A further six subjects (16%) had isolated upper extremity osteopenia or osteoporosis. Multivariate analysis showed a direct relationship between the number of chemotherapy drugs administered and the presence of osteopenia or osteoporosis in the lower extremities (P = 0.03). Young survivors of childhood solid tumors are at increased risk of developing premature osteopenia or osteoporosis, and screening evaluations and follow-up are warranted.

Abstract
PURPOSE To evaluate whether repeated courses of high-dose methylprednisolone (HDMP) affect the lumbar spine bone mineral density (BMD) in children with chronic idiopathic thrombocytopenic purpura (ITP). MATERIALS AND METHODS This study included 24 patients with chronic ITP and 149 healthy controls. The patients were allocated into three groups according to the number of HDMP courses (30 mg/kg per day as a single dose for 7 days); group 1 (10 patients), group 2 (9 patients), and group 3 (5 patients) had received less than 5, 6-10, and more than 10 courses, respectively. Lumbar spine BMD and body composition were measured using dual energy X-ray absorptiometry of lumbar spine (L2-L4), and volumetric bone mineral density (vBMD) values were calculated and compared with the controls. The z score of the vBMD was also calculated and compared in the patients of each other groups. Serum markers of the bone turnover were measured to exclude other factors that could effect BMD. RESULTS The vBMD values of the patients, corrected BMDs for age, were significantly lower than the values of controls (P = 0.018). It was significantly lower in group 3 than groups 1 and 2 (P = 0.005 and P = 0.006, respectively), but there was no statistically significant difference between groups 1 and 2 (P = 0.87). The vBMD z scores were significantly lower in group 3 than in groups 1 and 2 (P = 0.003 and P = 0.004, respectively), and also in group 2 than in group 1 (P = 0.034). There were a weak negative correlation between the cumulative dose of HDMP and vBMD (r = -0.39, P = 0.054), and strong negative correlation between the cumulative dose of HDMP and vBMD z score (r = -0.63, P = 0.001). CONCLUSION Children with chronic ITP are at risk for decreased BMD because of the repeated courses of HDMP; especially more than 2100 mg of cumulative dose. We therefore recommend that BMD should be monitored in patients with chronic ITP who received repeated courses of HDMP.

Abstract
PURPOSE Treatment for acute lymphoblastic leukemia (ALL) in childhood results in a reduction in bone mineral density (BMD). Whether there is a recovery of this lost bone mass in survivors of ALL is not known. We sought to determine if changes in BMD are common long-term sequelae in children with ALL. METHODS Bone mineral densitometry of the lumbar spine and femoral neck was performed on 106 patients. The results were compared with those of age-matched normal controls. The effect of treatment was examined in those with low BMD compared with the remainder of the study group. RESULTS When data were tested with respect to age, sex, and age and sex, no difference was observed in BMD between survivors of childhood ALL and controls. In the subgroup of patients with low BMD, the difference was not related to age, age at diagnosis, or years since diagnosis. Low BMD of the spine was not explained by radiotherapy (RT), methotrexate (MTX) dose, or corticosteroid dose. Low BMD of the femur was not explained by RT. However, those with low femoral BMD were more likely to have received high-dose MTX or higher-dose corticosteroids compared with the remainder of the group. CONCLUSION It appears that survivors of childhood ALL as a whole recover normal BMD. However, those patients who received a total MTX dose of greater than 40000 mg/m(2) or a total corticosteroid dose of greater than 9000 mg/m(2) may not recover normal BMD and therefore should be screened for decreased BMD of the femoral neck.
