Alterations in hypothalamic-pituitary axis (HPA) hormones 6 months after cranial radiotherapy in adult patients with primary brain tumors outside the HPA region. Mol Biol Rep 2024; 51:373. [PMID: 38418676 DOI: 10.1007/s11033-024-09257-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Accepted: 01/15/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Cranial radiotherapy is a common treatment for brain tumors, but it can affect the hypothalamic-pituitary (H-P) axis and lead to hormonal disorders. This study aimed to compare serum levels of HPA hormones before and after cranial radiation. MATERIALS AND METHODS This study involved 27 adult patients who underwent brain tumor resection before the initiation of radiotherapy, and none had metastatic brain tumors. All participants had the HPA within the radiation field, and their tumors were located in brain areas outside from the HPA. Serum levels of HPA hormones were recorded both before and 6 months after cranial radiotherapy. RESULTS A total of 27 adult patients, comprising 16 (59.3%) males and 11 (40.7%) females, with a mean age of 56.37 ± 11.38 years, were subjected to evaluation. Six months post-radiotherapy, serum levels of GH and TSH exhibited a significant decrease. Prior to radiotherapy, a substantial and direct correlation was observed between TSH and FSH (p = 0.005) as well as LH (p = 0.014). Additionally, a significant and direct relationship was noted between serum FSH and LH (p < 0.001) before radiotherapy. After radiotherapy, a significant and direct correlation persisted between TSH and FSH (p = 0.003) as well as LH (p = 0.005), along with a significant and direct relationship between serum FSH and LH (p < 0.001). Furthermore, a significant and direct association was identified between changes in serum GH levels and FSH (p = 0.04), as well as between serum LH and FSH (p < 0.001). CONCLUSION Reduced serum levels of HPA hormones are a significant complication of cranial radiotherapy and should be evaluated in follow-up assessments.

Abstract
Intracranial germ cell tumors (iGCTs) are rare malignant neoplasms that mainly affect children and adolescents. The incidence, clinical presentation, and prognosis of iGCTs exhibit high heterogeneity. Previous studies have primarily focused on eliminating tumors, reducing tumor recurrence, and improving survival rates, while neglecting the impact of the tumors and their treatment on neuroendocrine function. Throughout the entire course of the disease, neuroendocrine dysfunction may occur and is frequently overlooked by oncologists, neurosurgeons, and radiologists. Endocrinologists, however, are more interested in this issue and have varying priorities at different stages of the disease. From onset to the diagnostic phase, most patients with iGCTs may present with symptoms related to impaired neuroendocrine function, or even experience these symptoms as their first indication of the condition. Particularly, a minority of patients with sellar/suprasellar lesions may exhibit typical imaging features and elevated tumor markers long after the onset of initial symptoms. This can further complicate the diagnosis process. During the peritumor treatment phase, the neuroendocrine function shows dynamic changes and needs to be evaluated dynamically. Once diabetes insipidus and dysfunction of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes occur, hormone replacement therapy should be administered promptly to ensure successful tumor treatment for the patient. Subsequently, during the long-term management phase after the completion of tumor treatment, the evaluation of growth and development as well as corresponding hormone replacement therapy are the most concerning and complex issues. Thus, this paper reviews the interest of endocrinologists in iGCTs at different stages.

Abstract
BACKGROUND Endocrine deficiencies, including hypothalamic-pituitary-gonadal axis (HPGA) impairment, are common in survivors of childhood and adolescent medulloblastoma. Still, data regarding pubertal development and fecundity are limited, and few studies assessed HPGA function in males. We aimed to describe HPGA function in a large cohort of patients with medulloblastoma. METHODS A retrospective study comprising all 62 medulloblastoma patients treated in our center between 1987 and 2021, who were at least 2 years from completion of therapy. HPGA function was assessed based on clinical data, biochemical markers, and questionnaires. RESULTS Overall, 76% of female patients had clinical or biochemical evidence of HPGA dysfunction. Biochemical evidence of diminished ovarian reserve was seen in all prepubertal girls (n = 4). Among the males, 34% had clinical or biochemical evidence of gonadal dysfunction, 34% had normal function, and 29% were age-appropriately clinically and biochemically prepubertal. The difference between males and females was significant (P = .003). Cyclophosphamide-equivalent dose was significantly associated with HPGA function in females, but not in males. There was no association between HPGA dysfunction and other endocrine deficiencies, length of follow-up, weight status, and radiation treatment protocol. Two female and 2 male patients achieved successful pregnancies, resulting in 6 live births. CONCLUSIONS HPGA dysfunction is common after treatment for childhood medulloblastoma. This is seen more in females, likely due to damage to the ovaries from spinal radiotherapy. Our findings may assist in counseling patients and their families regarding risk to future fertility and need for fertility preservation.

Growth hormone deficiency and other endocrinopathies after childhood brain tumors: results from a close follow-up in a cohort of 242 patients. J Endocrinol Invest 2021; 44:2367-2374. [PMID: 33683662 DOI: 10.1007/s40618-021-01541-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Accepted: 02/19/2021] [Indexed: 10/22/2022]
Abstract
PURPOSE Brain tumors are the most common solid tumor in children. The prevalence of survivors from these cancers has been increasing, presenting endocrine sequelae in more than 40% of the cases. Our aim was to characterize the endocrinopathies diagnosed in this population, exploring the outcomes of growth hormone treatment. METHODS We have performed a retrospective analysis of the survivors that were followed-up through a close protocol at our endocrine late-effects clinic. RESULTS 242 survivors, followed during 6.4 (0-23.4) years, were considered. The median age at tumor diagnosis was 6.7 (0-18) years and pilocytic astrocytoma was the most frequent neoplasm (33.5%). The prevalence of endocrinopathies was of 71.5%, with growth hormone deficiency being the most frequent (52.9%). An indirect correlation between the age at the beginning of somatropin and growth velocity in the first year of treatment was observed. Those treated with craniospinal radiotherapy presented a smaller final upper/lower segments ratio comparing with those that only received cranial radiotherapy. However, their final height was not compromised when compared to their family height target. We found pubertal delay in 12%; accelerated/precocious puberty in 13.2%; central and primary hypogonadism in 21.9% and 3.3%, respectively; primary and central hypothyroidism in 23.6% and 14.5%, respectively; thyroid nodules in 7.4%; ACTH deficiency in 10.3% and diabetes insipidus in 12%. CONCLUSION This study reveals a higher prevalence of endocrinopathies in brain tumors survivors and explores the influence of craniospinal irradiation in the adult body proportions. It reinforces the importance of routine follow-up among survivors.

Quality of survival assessment in European childhood brain tumour trials, for children below the age of 5 years. Eur J Paediatr Neurol 2020; 25:59-67. [PMID: 31753708 DOI: 10.1016/j.ejpn.2019.10.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2019] [Revised: 10/03/2019] [Accepted: 10/12/2019] [Indexed: 11/23/2022]
Abstract
The highest incidence rate of childhood brain tumours is in children below the age of five years, who are particularly vulnerable to the effects of treatments. The assessment of quality of survival (QoS) in multiple domains is essential to compare the outcomes for different tumour types and treatment regimens. The aim of this position statement is to present the domains of health and functioning to be assessed in children from birth to five years, to advance the collection of a common QoS data set in European brain tumour trials. The QoS group of the European Society of Paediatric Oncology (SIOP-E) Brain Tumour group conducted consensus discussions over a period of six years to establish domains of QoS that should be prioritised in clinical trials involving children under 5 years. The domains of health and functioning that were agreed to affect QoS included: medical outcomes (e.g. vision, hearing, mobility, endocrine), emotion, behaviour, adaptive behaviour, and cognitive functioning. As for children aged five years and older, a 'core plus' approach is suggested in which core assessments are recommended for all clinical trials. The core component for children from birth to three years includes indirect assessment which, in this age-group, requires proxy assessment by a parent, of cognitive, emotional and behaviour variables and both direct and indirect endocrine measures. For children from four years of age direct cognitive assessment is also recommended as 'core'. The 'plus' components enable the addition of assessments which can be selected by individual countries and/or by, age-, treatment-, tumour type- and tumour location-specific trials.

Abstract
BACKGROUND The most of the current studies include patients who are different by the etiology of secondary adrenal insufficiency (SAI), or investigate SAI among other late effects of the radiation therapy. AIMS To describe the features of SAI and to select the best method of screening SAI in adult patients followed complex treatment of nonpituitary brain tumors in childhood. MATERIALS AND METHODS It was the retrospective cross-sectional study. 31 patients after the complex treatment of nonpituitary brain tumors in childhood and 20 healthy volunteers were examined. Age and sex ratio were comparable between the groups. Biochemical and clinical blood tests, levels of cortisol, ACTH, DHEA-C were evaluated. The insulin tolerance test (ITT) was performed for all patients and 11 volunteers. RESULTS The prevalence of SAI by ITT was 45.2%. The levels of basal cortisol (BC) were significantly higher in patients without SAI in comparison with the SAI group and volunteers (505 [340; 650] vs 323 [233; 382] and 372 [263; 489] nmol / l; pSAI- without_SAI=0.001; pwihtout_SAI-healthy = 0.04). The SAI group had DHEA-C significantly lower than in other groups one (3.1 [1.8; 3.4] vs 5.1 [2.5; 6.4] and 6.8 [4.1; 8.9]; рSAI- without_SAI = 0.036; pSAI-healthy = 0.001). ROC analysis showed that BC and DHEA-S can be used as high-quality screening tests for SAI (AUC = 89.3% and 88.3%). The maximum level of cortisol (656 [608-686] vs 634 [548-677]; p = 1) and the time of its increase (45 and 60 min) did not differ during ITT in patients without SAI and volunteers. Side effects: delayed hypoglycemia occurred in 4/14 patients of the SAI group 4090 minutes late of injection 60-80 ml of 40% glucose solution for stopping hypoglycemia in the test. CONCLUSIONS 45.2% of patients followed craniospinal irradiation had SAI that is characterized by a decrease in DHEA-C levels. A highly normal level of basal cortisol was observed in 45% of patients without SAI. DHEA-C and blood cortisol can be used for SAI screening.

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
PURPOSE To explore for fatigue-related regions and the radiotherapy (RT) dose-fatigue relationship in nasopharyngeal cancer (NPC) survivors. METHODS Eighty disease-free NPC survivors completed the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN) after RT. Fatigue was evaluated by the MDASI-HN fatigue item (MDASI-HN-F) and Common Terminology Criteria for Adverse Events v3.0 (CTC-AE), between 6 and 36 months after RT to determine the presence of chronic fatigue. Skull base MRIs and planning CT/RT dose were retrievable for 56 patients. Dosimetric data were extracted for 10 MRI-defined potential fatigue at-risk structures (FARS): brainstem (BS), pituitary gland (PG), hypothalamus (HT), basal ganglia, internal capsule, pineal gland, sub-thalamic nuclei, thalamus, substantia nigra, and hippocampus (HC). Recursive partitioning analysis (RPA) was used to identify dose-volume effects associated with chronic fatigue. RESULTS 56 pts formed the cohort. Thirty patients (54%) reported any fatigue per MDASI-HN-F. Thirty-three pts (59%) had any fatigue by CTC-AE. The maximum point doses (Dmax) for PG, BS, HC, and HT were numerically higher in patients with fatigue. Dmax and Dmean of the PG were significantly higher in patients with chronic fatigue, p ≤ 0.01. A dose-volume threshold of PG V52 Gy ≥16% (LogWorth 2.4, AUC 0.7) was identified on RPA, and potential sensitivity to the PG doses was observed in younger patients (<53 years-old). CONCLUSION A dose-fatigue relationship was identified for the pituitary gland, both patient-reported and observer ratings. We recommend limiting the Dmax of PG to <54 Gy and V52 Gy to <16%, particularly in young NPC patients, during plan optimization when achievable.

Abstract
Endocrine abnormalities are common among childhood cancer survivors. Abnormalities of the hypothalamic-pituitary-adrenal axis (HPAA) are relatively less common, but the consequences are severe if missed. Patients with tumours located and/or had surgery performed near the hypothalamic-pituitary region and those treated with an accumulative cranial radiotherapy dose of over 30 Gy are most at risk of adrenocorticotrophic hormone (ACTH) deficiency. Primary adrenal insufficiency may occur in patients with tumours located in or involving one or both adrenals. The effects of adjunct therapies also need to be considered, particularly, new immunotherapies. High-dose and/or prolonged courses of glucocorticoid treatment can result in secondary adrenal insufficiency, which may take months to resolve and hence reassessment is important to ensure patients are not left on long-term replacement steroids inappropriately. The prevalence and cumulative incidences of HPAA dysfunction are difficult to quantify because of its non-specific presentation and lack of consensus regarding its investigations. The insulin tolerance test remains the gold standard for the diagnosis of central cortisol deficiency, but due to its risks, alternative methods with reduced diagnostic sensitivities are often used and must be interpreted with caution. ACTH deficiency may develop many years after the completion of oncological treatment alongside other pituitary hormone deficiencies. It is essential that health professionals involved in the long-term follow-up of childhood cancer survivors are aware of individuals at risk of developing HPAA dysfunction and implement appropriate monitoring and treatment.

Abstract
OBJECTIVE To formulate clinical practice guidelines for the endocrine treatment of hypothalamic-pituitary and growth disorders in survivors of childhood cancer. PARTICIPANTS An Endocrine Society-appointed guideline writing committee of six medical experts and a methodologist. CONCLUSIONS Due to remarkable improvements in childhood cancer treatment and supportive care during the past several decades, 5-year survival rates for childhood cancer currently are >80%. However, by virtue of their disease and its treatments, childhood cancer survivors are at increased risk for a wide range of serious health conditions, including disorders of the endocrine system. Recent data indicate that 40% to 50% of survivors will develop an endocrine disorder during their lifetime. Risk factors for endocrine complications include both host (e.g., age, sex) and treatment factors (e.g., radiation). Radiation exposure to key endocrine organs (e.g., hypothalamus, pituitary, thyroid, and gonads) places cancer survivors at the highest risk of developing an endocrine abnormality over time; these endocrinopathies can develop decades following cancer treatment, underscoring the importance of lifelong surveillance. The following guideline addresses the diagnosis and treatment of hypothalamic-pituitary and growth disorders commonly encountered in childhood cancer survivors.

Abstract
AIM Childhood brain tumour survivors have a high risk of endocrine morbidity. This study evaluated the growth, pubertal development and gonadal function in survivors of childhood brain tumours and identified factors associated with the problems we observed. METHODS The 52 subjects (52% male) were diagnosed in 1983-1997 and treated for brain tumours at Tampere University Hospital, Finland. They were followed up at a mean age of 14.2 (3.8-28.7) years, a mean of 7.5 (1.5-15.1) years after diagnosis. RESULTS We found that 30 (58%) participants had a lower height standard deviation score at follow-up than at diagnosis and short stature at follow-up was associated with tumour malignancy (p = 0.005), radiotherapy (p = 0.004), chemotherapy (p = 0.024), growth hormone deficiency (p < 0.001), hypogonadism (p = 0.044) and delayed puberty (p = 0.021). We found that five needed sex hormones to induce puberty, one had precocious puberty, 12 (23%) had growth hormone deficiency and eight (22%) of the 36 pubertal or postpubertal patients had hypogonadism. Testicular volume was low in 83% of late or postpubertal male survivors. CONCLUSION Growth impairment, growth hormone deficiency and hypogonadism were common in childhood brain tumour survivors and low testicular volume was also common in male survivors. Lifelong annual follow-up checks are indicated for survivors.

Abstract
AIM The aim of this study was to coordinate the structured psychosocial, neurocognitive and educational follow-up of children treated for brain tumours with the medical protocol and apply the model in two Swedish healthcare regions. METHODS We invited all children living in the two regions, who had been diagnosed with a brain tumour from October 1, 2010, through June 30, 2012, to participate along with their parents. The follow-up programme evaluated the emotional status of the parents and patients and assessed the children's general cognitive level, working memory, speed of performance, executive functions and academic achievement from diagnosis through to adult care. RESULTS During the study period, 61 children up to the age of 17.1 years were diagnosed with a brain tumour, but 18 of these were excluded for various reasons. The majority of the mothers (70%) displayed significantly poor emotional status, as did 34% of the fathers and 21% of the children. The majority of the children (57%) also showed poor neurocognitive performance and needed special adaptations at school (66%). CONCLUSION Our findings indicate the need for coordinated, multiprofessional follow-up programmes, well anchored in the healthcare organisation, for children diagnosed with brain tumours.

Endocrine outcomes with proton and photon radiotherapy for standard risk medulloblastoma. Neuro Oncol 2015; 18:881-7. [PMID: 26688075 DOI: 10.1093/neuonc/nov302] [Citation(s) in RCA: 102] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2015] [Accepted: 11/03/2015] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Endocrine dysfunction is a common sequela of craniospinal irradiation (CSI). Dosimetric data suggest that proton radiotherapy (PRT) may reduce radiation-associated endocrine dysfunction but clinical data are limited. METHODS Seventy-seven children were treated with chemotherapy and proton (n = 40) or photon (n = 37) radiation between 2000 and 2009 with ≥3 years of endocrine screening. The incidence of multiple endocrinopathies among the proton and photon cohorts is compared. Multivariable analysis and propensity score adjusted analysis are performed to estimate the effect of radiotherapy type while adjusting for other variables. RESULTS The median age at diagnosis was 6.2 and 8.3 years for the proton and photon cohorts, respectively (P = .010). Cohorts were similar with respect to gender, histology, CSI dose, and total radiotherapy dose and whether the radiotherapy boost was delivered to the posterior fossa or tumor bed. The median follow-up time was 5.8 years for proton patients and 7.0 years for photon patients (P = .010). PRT was associated with a reduced risk of hypothyroidism (23% vs 69%, P < .001), sex hormone deficiency (3% vs 19%, P = .025), requirement for any endocrine replacement therapy (55% vs 78%, P = .030), and a greater height standard deviation score (mean (± SD) -1.19 (± 1.22) vs -2 (± 1.35), P = .020) on both univariate and multivariate and propensity score adjusted analysis. There was no significant difference in the incidence of growth hormone deficiency (53% vs 57%), adrenal insufficiency (5% vs 8%), or precocious puberty (18% vs 16%). CONCLUSIONS Proton radiotherapy may reduce the risk of some, but not all, radiation-associated late endocrine abnormalities.

Abstract
INTRODUCTION Survival following treatment of paediatric medulloblastomas has significantly improved over the past few decades, but as a consequence, late effects, particularly endocrine sequelae, have been recognized. The complete picture of late effects, however, has been limited by short duration of follow-up. AIM To establish the evolution of endocrine sequelae in patients treated for medulloblastoma. METHODS Single-centre analysis of medulloblastoma treatment and endocrine sequelae in patients diagnosed between 1982 and 2002. RESULTS A total of 109 patients were treated for medulloblastoma, with various treatment modalities involving radio- and chemotherapy. Only 45 (41%) patients remained alive, and details of treatment and late effects were available for 35 (25 m). The median age at diagnosis was 8 (range 2-14) years, and the median follow-up was 18 (range 10-28) years. Growth hormone deficiency (GHD) was the most prevalent hormone deficiency (97%), followed by primary hypothyroidism (60%) and adrenocorticotrophic hormone (ACTH) deficiency (45·5%). The median time from end of treatment to loss of growth hormone was 1·7 (range 0·7-15) years, ACTH deficiency 2·9 (range 0·75-7·5) years and hypothyroidism 4·1 (range 0·7-11·4) years. Twenty-three percentage developed hypogonadism (17% primary and 6% secondary), whilst precocious puberty was seen in 20%. Endocrinopathies appeared to be more prevalent in those treated with concomitant chemotherapy and radiotherapy. CONCLUSIONS Prevalence of endocrine sequelae in medulloblastoma survivors is high, and evolution of endocrine dysfunction can occur as late as 15 years from treatment completion; hence, long-term close monitoring of growth, puberty and gonadal function is essential.

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

Abstract
INTRODUCTION There is increasing recognition of the long-term sequelae of brain tumours treated in childhood. Five year survival rates now exceed 75% and assessing the quality of survival (QoS) in multiple domains is essential to any comparison of the benefits and harms of treatment regimens. AIM The aim of this position statement is to rationalise assessments and facilitate collection of a common data set across Europe. Sufficient numbers of observations can then be made to enable reliable comparisons between outcomes following different tumour types and treatments. METHODS This paper represents the consensus view of the QoS working group of the Brain Tumour group of the European Society of Paediatric Oncology regarding domains of QoS to prioritise for assessment in clinical trials. This consensus between clinicians and researchers across Europe has been arrived at by discussion and collaboration over the last eight years. RESULTS Areas of assessment discussed include core medical domains (e.g. vision, hearing, mobility, endocrine), emotion, behaviour, adaptive behaviour and cognitive functioning. CONCLUSIONS A 'core plus' approach is suggested in which core assessments (both direct and indirect tests) are recommended for all clinical trials. The core component is a relatively brief screening assessment that, in most countries, is a sub-component of routine clinical provision. The 'plus' components enable the addition of assessments which can be selected by individual countries and/or tumour-, age-, and location-specific groups. The implementation of a QoS protocol common to all European clinical studies of childhood brain tumours is also discussed.

Abstract
BACKGROUND Post-surgical radiotherapy (RT) in combination with chemotherapy is considered as standard of care for medulloblastoma in children. Chemotherapy has been introduced to improve survival and to reduce RT-induced adverse effects. Reduction of RT-induced adverse effects was achieved by deleting (craniospinal) RT in very young children and by diminishing the dose and field to the craniospinal axis and reducing the boost volume to the tumour bed in older children. OBJECTIVES PRIMARY OBJECTIVES 1. to determine the event-free survival/disease-free survival (EFS/DFS) and overall survival (OS) in children with medulloblastoma receiving chemotherapy as a part of their primary treatment, as compared with children not receiving chemotherapy as part of their primary treatment; 2. to determine EFS/DFS and OS in children with medulloblastoma receiving standard-dose RT without chemotherapy, as compared with children receiving reduced-dose RT with chemotherapy as their primary treatment. SECONDARY OBJECTIVES to determine possible adverse effects of chemotherapy and RT, including long-term adverse effects and effects on quality of life. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2013, Issue 7), MEDLINE/PubMed (1966 to August 2013) and EMBASE/Ovid (1980 to August 2013). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trial databases (August 2013). SELECTION CRITERIA Randomised controlled trials (RCTs) evaluating the above treatments in children (aged 0 to 21 years) with medulloblastoma. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, data extraction and risk of bias assessment. We performed analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. Where possible, we pooled results. MAIN RESULTS The search identified seven RCTs, including 1080 children, evaluating treatment including chemotherapy and treatment not including chemotherapy. The meta-analysis of EFS/DFS not including disease progression during therapy as an event in the definition showed a difference in favour of treatment including chemotherapy (hazard ratio (HR) 0.70; 95% confidence interval (CI) 0.54 to 0.91; P value = 0.007; 2 studies; 465 children). However, not including disease progression as an event might not be optimal and the finding was not confirmed in the meta-analysis of EFS/DFS including disease progression during therapy as an event in the definition (HR 1.02; 95% CI 0.70 to 1.47; P value = 0.93; 2 studies; 300 children). Two individual studies using unclear or other definitions of EFS/DFS also showed no clear evidence of difference between treatment arms (one study with unclear definition of DFS: HR 1.67; 95% CI 0.59 to 4.71; P value = 0.34; 48 children; one study with other definition of EFS: HR 0.84; 95% CI 0.58 to 1.21; P value = 0.34; 233 children). In addition, it should be noted that in one of the studies not including disease progression as an event, the difference in DFS only reached statistical significance while the study was running, but due to late relapses in the chemotherapy arm, this significance was no longer evident with longer follow-up. There was no clear evidence of difference in OS between treatment arms (HR 1.06; 95% CI 0.67 to 1.67; P value = 0.80; 4 studies; 332 children). Out of eight reported adverse effects, of which seven were reported in one study, two (severe infections and fever/neutropenia) showed a difference in favour of treatment not including chemotherapy (severe infections: risk ratio (RR) 5.64; 95% CI 1.28 to 24.91; P value = 0.02; fever/neutropenia: RR not calculable; Fisher's exact P value = 0.01). There was no clear evidence of a difference between treatment arms for other adverse effects (acute alopecia: RR 1.00; 95% CI 0.92 to 1.08; P value = 1.00; reduction in intelligence quotient: RR 0.78; 95% CI 0.46 to 1.30; P value = 0.34; secondary malignancies: Fisher's exact P value = 0.5; haematological toxicity: RR 0.54; 95% CI 0.20 to 1.45; P value = 0.22; hepatotoxicity: Fisher's exact P value = 1.00; treatment-related mortality: RR 2.37; 95% CI 0.43 to 12.98; P value = 0.32; 3 studies). Quality of life was not evaluated. In individual studies, the results in subgroups (i.e. younger/older children and high-risk/non-high-risk children) were not univocal.The search found one RCT comparing standard-dose RT with reduced-dose RT plus chemotherapy. There was no clear evidence of a difference in EFS/DFS between groups (HR 1.54; 95% CI 0.81 to 2.94; P value = 0.19; 76 children). The RCT did not evaluate other outcomes and subgroups.The presence of bias could not be ruled out in any of the studies. AUTHORS' CONCLUSIONS Based on the evidence identified in this systematic review, a benefit of chemotherapy cannot be excluded, but at this moment we are unable to draw a definitive conclusion regarding treatment with or without chemotherapy. Treatment results must be viewed in the context of the complete therapy (e.g. the effect of surgery and craniospinal RT), and the different chemotherapy protocols used. This systematic review only allowed a conclusion on the concept of treatment, not on the best strategy regarding specific chemotherapeutic agents and radiation dose. Several factors complicated the interpretation of results including the long time span between studies with important changes in treatment in the meantime. 'No evidence of effect', as identified in this review, is not the same as 'evidence of no effect'. The fact that no significant differences between treatment arms were identified could, besides the earlier mentioned reasons, also be the result of low power or too short a follow-up period. Even though RCTs are the highest level of evidence, it should be recognised that data from non-randomised studies are available, for example on the use of chemotherapy only in very young children with promising results for children without metastatic disease. We found only one RCT addressing standard-dose RT without chemotherapy versus reduced-dose RT with chemotherapy, so no definitive conclusions can be made. More high-quality research is needed.

Abstract
INTRODUCTION Childhood brain tumor survivors (CBTS) are at increased risk to develop endocrine disorders. Alerted by two cases who experienced delay in diagnosis of endocrine deficiencies within the first 5 years after brain tumor diagnosis, our aim was to investigate the current screening strategy and the prevalence of endocrine disorders in survivors of a childhood brain tumor outside of the hypothalamic-pituitary region, within the first 5 years after diagnosis. PROCEDURES Firstly, we performed a retrospective study of 47 CBTS treated in our center, diagnosed between 2008 and 2012. Secondly, the literature was reviewed for the prevalence of endocrine disorders in CBTS within the first 5 years after diagnosis. RESULTS Of 47 CBTS eligible for evaluation, in 34% no endocrine parameters had been documented at all during follow up. In the other 66%, endocrine parameters had been inconsistently checked, with different parameters at different time intervals. In 19% of patients an endocrine disorder was found. At literature review 22 studies were identified. The most common reported endocrine disorder within the first 5 years after diagnosis was growth hormone deficiency (13-100%), followed by primary gonadal dysfunction (0-91%) central hypothyroidism (0-67%) and primary/subclinical hypothyroidism (range 0-64%). CONCLUSION Endocrine disorders are frequently seen within the first 5 years after diagnosis of a childhood brain tumor outside of the hypothalamic-pituitary region. Inconsistent endocrine follow up leads to unnecessary delay in diagnosis and treatment. Endocrine care for this specific population should be improved and standardized. Therefore, high-quality studies and evidence based guidelines are warranted.

Abstract
Acute lymphoblastic leukaemia (ALL) is the most common childhood malignancy. The survival rate in the Scandinavian countries is now around 85 %. ALL patients treated with cranial radiotherapy (CRT) are at risk for growth hormone deficiency (GHD), but little is known about other pituitary insufficiencies, e.g. ACTH. Adult ALL patients (median age at study 25 years), treated with 24 Gy (18-30) of CRT during childhood were investigated. We performed an insulin tolerance test (ITT) to evaluate cortisol secretion. We measured basal serum ACTH and cortisol levels before and after 5 years of GH therapy. 14 out of 37 (38 %) ALL patients had a subnormal cortisol response to an ITT (257-478 nmol/L) while there was no significant difference in basal cortisol levels between 44 patients and controls (P > 0.3). Female, but not male ALL patients had significantly lower ACTH levels compared to controls (P = 0.03). After 5 years of GH therapy only male ALL patients had significantly lowered basal plasma cortisol (P = 0.02). ALL survivors, treated with a moderate dose CRT, have a central adrenal insufficiency 20 years after diagnosis. An increased awareness of the risk for an adrenal insufficiency is of importance and life-long surveillance of the entire hypothalamic-pituitary axis is recommended in these patients.

Abstract
PURPOSE Medulloblastoma (MB) is one of the most frequent and sensitive to radiation aggressive brain tumor in children. Abnormalities of the thyroid function are common complications of head and neck irradiation for childhood cancer. The aim of this study was to assess thyroid function in children treated for medulloblastoma according to the treatment protocol phase. PATIENTS AND METHODS Twenty-three children with MB were enrolled to this study. All patients underwent chemotherapy and radiotherapy to the whole craniospinal axis and boost with the conformal therapy restricted to the tumor bed to a total dose of 54 Gy. Thyroid function was evaluated based on thyroid-stimulating hormone (TSH), free thyroxine (fT4) levels controlled before MB treatment, directly after irradiation and at the end of the treatment protocol. Ultrasonography has been used to detect parenchymal abnormalities. RESULTS All patients presented normal thyroid hormone range before chemotherapy. Hypothyroidism was found in 12 patients in the course of treatment, in 2 patients hormone deficits diagnosed directly after irradiation, in 10 patients such condition was observed at the end of the whole therapy. All of these patients needed thyroid hormone substitution. None of them presented clinical symptoms of hypothyroidism. Ultrasound-detected abnormalities have been found in 20 patients. CONCLUSIONS It is crucial to monitor the functions of the thyroid gland in children treated for medulloblastoma because of the high risk of hypothyroidism resulting from the treatment. The change in the echogenicity of the thyroid gland may be an early marker for a dysfunction of this organ in children treated for medulloblastoma.

Abstract
To assess the effect of human growth hormone (hGH) therapy and other factors on tumor recurrence after treatment of pediatric brain tumors (BTs), we retrospectively analyzed data from 108 craniopharyngioma, medulloblastoma, and ependymoma patients. Risk factors were identified using multifactorial univariate regression analysis. Recurrences occurred in 41 and second malignant neoplasms in 4 patients. There were significant correlations for completeness of tumor removal and recurrence-free survival (RFS). 13/44 hGH-treated and 28/59 non-hGH-treated children relapsed. This difference was found only for medulloblastomas and accounted for by higher rates of incomplete tumor removal in non-hGH patients. Craniopharyngioma recurrence correlated only with RFS. Malignant BT recurrence correlated with completeness of tumor removal, chemotherapy, and RFS. 4 children developed SMNs, 3/4 after hGH therapy. Our regression model yielded accurate within-sample prediction of recurrence for 90% of the study population. We conclude that hGH therapy after treatment of pediatric BTs does not increase tumor recurrence risk.

Abstract
Medulloblastoma is the most common infratentorial malignant tumour under 15 years of age. In recent protocols, the patients are stratified for treatment in standard risk or high risk, according to the clinical variables as age, localized or disseminated disease, degree of surgical resection and more recently expected biological behaviour based on retrospective and prospective studies of former samples analyzed. The objectives for future treatments are reduce morbidity without jeopardizing survival.

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
OBJECT Optimal treatment of primary and recurrent craniopharyngiomas remains controversial. Radical resection and limited resection plus radiation therapy yield similar rates of disease control and overall survival. The data are much less clear for recurrent tumors. The authors report their experience with radical resection of both primary and recurrent craniopharyngiomas in children and compare the outcomes between the 2 groups. METHODS A retrospective analysis was performed in 86 children younger than 21 years of age who underwent a total of 103 operations for craniopharyngioma between 1986 and 2008; these were performed by the senior author. The goal was resection with curative intent in all patients. Two patients were lost to follow-up and were excluded from analysis. The mean age at the time of surgery was 9.6 years, and the mean follow-up was 9.0 years. RESULTS All 57 children with primary tumors underwent gross-total resection (GTR). A GTR was achieved in significantly fewer children with recurrent tumors (18 [62%] of 29). There were 3 perioperative deaths (3%). Tumor recurred after GTR in 14 (20%) of 71 patients. Overall survival and progression-free survival were significantly better in patients with primary tumors at time of presentation to the authors' institution. There were no significant differences in the neurological, endocrinological, visual, or functional outcomes between patients with primary and those with recurrent tumors. Factors negatively affecting overall survival and progression-free survival include subtotal resection (recurrent tumors only), tumor size >or= 5 cm, or presence of hydrocephalus or a ventriculoperitoneal shunt. Prior radiation therapy and increasing tumor size were both risk factors for incomplete resection at reoperation. CONCLUSIONS In the hands of surgeons with experience with craniopharyngiomas, the authors believe that radical resection at presentation offers the best chance of disease control and potential cure with acceptable morbidity. While GTR does not preclude recurrence and is more difficult to achieve in recurrent tumors, especially large and previously irradiated tumors, radical resection is still possible in patients with recurrent craniopharyngiomas with morbidity similar to that of primary tumors.

Abstract
Local recurrence following radical resection is one of the most common complications of pediatric craniopharyngioma. Only 28 cases of ectopic recurrence of craniopharyngioma have been reported in the literature, and only 13 cases occurred in patients originally treated as children. In this consecutive series of 86 children who underwent radical resection of primary and recurrent craniopharyngiomas, 4 patients (4.7%) experienced ectopic tumor recurrence, accounting for 27% of all recurrences after gross-total resection. The authors report on the successful surgical treatment of these 4 patients and the impact of ectopic craniopharyngioma recurrence on survival.

Abstract
A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of different tumours and normal tissues. It is estimated that in paediatric cancers, proton beams are of potential importance in 80-100 children annually in Sweden. About 20 of the patients have medulloblastoma. The main purpose is to reduce late sequelae, but these are also increased chances to avoid myelosupression during e.g. concomitant chemo-radiation and to further intensify the chemotherapy.

Abstract
OBJECT Given the potential morbidity of cranial irradiation in young children, the risk-benefit analysis of limited surgery plus irradiation versus radical resection may favor the latter strategy. The purpose of this study was to assess the oncological, endocrinological, and functional outcomes of patients 5 years of age and younger who underwent radical resection of craniopharyngiomas. METHODS Between 1991 and 2008, 19 children age < or = 5 years were diagnosed with a craniopharyngioma and underwent radical resection by the senior author (J.H.W.). Data were retrospectively collected on these 19 patients (11 males, 8 females; mean age 3.2 years) to assess the efficacy and impact of surgical treatment. RESULTS Eighteen (95%) of 19 patients underwent gross-total resection (GTR) confirmed by intraoperative inspection and postoperative imaging. There was no operative death and 18 of (95%) 19 patients were alive at a mean follow-up of 9.4 years (median 8.3 years). Six patients (31%) had a total of 7 tumor recurrences treated by repeat GTR in 5 patients and Gamma knife surgery in 1 patient. No patient required conventional, fractionated radiation therapy. Disease control was achieved surgically in 17 (89.5%) patients and with surgery and Gamma knife surgery in 1 patient, yielding an overall rate of disease control of 95% without the use of conventional radiotherapy. New-onset diabetes insipidus occurred in 50% of patients. Vision worsened in 1 patient, and there was no long-term neurological morbidity. CONCLUSIONS In this retrospective series, children aged < or = 5 years with craniopharyngiomas can have excellent outcomes with minimal morbidity after radical resection by an experienced surgeon. Disease control in this population can be successfully achieved with GTR alone in the majority of cases, avoiding the detrimental effects of radiotherapy in this vulnerable population.

Abstract
INTRODUCTION Irradiation of brain tumors (BT) in children can lead to the loss of pituitary function, predominantly manifesting as deficiencies in GH and ACTH. OBJECTIVE To assess the incidence and nature of pituitary deficiency in relation to initial tumor location in children after radiotherapy of BT. METHODS Twenty survivors (16 males and 4 females) of radiation-treated BT aged 1.4-10.9 (median 3.6) yr at diagnosis were studied, 10 with supratentorial and 10 with infratentorial BT. Radiation doses to the hypothalamus- pituitary (HP) area ranged from 30 to 54 (median 45) Gray. Follow-up was 9.4-16.9 (median 12.2) yr. Basal pituitary hormone levels were measured every 6 months. When growth failure became evident or pituitary deficiency was suspected, provocation tests of the HP axis were performed to assess GH, ACTH, and TSH function. RESULTS GH deficiency (GHD) developed in 17/20 (85%) children. In 10 patients, it occurred 4 yr after radiotherapy and in 2, 11 and 12 yr after radiotherapy. Six (30%) patients developed secondary hypothyroidism and 4 (20%) developed ACTH deficiency. Precocious puberty occurred in 2 girls. The course of development and the severity of hormone deficiencies were similar for supratentorial and infratentorial tumors. CONCLUSION The major hormonal effect of BT irradiation in children is GHD, which may sometimes take more than 10 yr to manifest. We confirm findings by others that ACTH insufficiency occurs less frequently in children than reported for adults. Tumor location has no prognostic significance regarding the loss of HP function.

Abstract
OBJECT The purpose of this study was to assess the impact of minimal residual calcification without enhancing tumor on the rate of recurrence after gross-total resection (GTR) of craniopharyngioma in children. METHODS Data were retrospectively collected in 86 patients younger than 21 years of age in whom 103 craniopharyngioma resections were performed by the senior author between 1986 and 2008. Forty-nine patients (27 boys and 22 girls, with a mean age of 8.6 years) fulfilled the criteria for inclusion in this study by having tumor calcification on the preoperative CT scan, undergoing GTR, and having complete postoperative CT and MR imaging and clinical follow-up. RESULTS Thirteen patients (27%) had residual calcification (< or = 2 mm in 12 patients; 3.5 mm in 1 patient) on their postoperative CT scan. At a mean follow-up of 9.4 years (median 10 years), 2 (15%) of 13 patients with and 10 (28%) of 36 patients without residual calcification experienced tumor recurrence. There were no significant differences between these groups in terms of the duration of follow-up, time to recurrence, rate of recurrence, or recurrence-free survival. CONCLUSIONS The absence or presence of minimal residual calcification does not have an impact on the risk of recurrence after GTR in pediatric craniopharyngiomas. The authors recommend withholding irradiation or other adjuvant therapy in the setting of minimal residual calcification without enhancing tumor. Close follow-up with frequent serial imaging in all patients after GTR is imperative to identify and treat early recurrence.

Abstract
PURPOSE To estimate the cumulative incidence of specific hormone deficiencies and the influence of hypothalamic-pituitary (HP) axis radiation dose in a cohort of children with embryonal brain tumors treated with risk-adapted craniospinal irradiation (CSI), conformal primary site irradiation, and high-dose chemotherapy. PATIENTS AND METHODS Clinical data and HP axis radiation dosimetry data were obtained from 88 eligible children. All patients received regular endocrine follow-up that included screening tests of thyroid function and stimulation testing for growth hormone deficiency (GHD), and adrenocorticotropin hormone deficiency. RESULTS The cumulative incidence of GHD, thyroid-stimulating hormone (TSH) deficiency, adrenocorticotropic hormone deficiency, and primary hypothyroidism at 4 years from diagnosis was 93% +/- 4%, 23% +/- 8%, 38% +/- 6%, and 65% +/- 7%, respectively. Radiation dosimetry to the HP axis was associated only with the development of TSH deficiency; the 4-year cumulative incidence was 44% +/- 19% and 11% +/- 8% (P = .014) for those receiving more or less than the median dose to the hypothalamus (>or= 42 v < 42 Gy), respectively. The median dose of CSI for the average-risk (AR) patients was 23.4 and 39.6 Gy (36 to 40.5 Gy) for the high-risk patients. The estimated mean decline in height Z-score after radiation therapy was greater in high-risk patients (-0.65 units/yr) when compared with AR patients (-0.54 units/yr; P = .039). CONCLUSION Pediatric patients with CNS embryonal tumors are at high risk for treatment-related hormone deficiencies. GHD and primary hypothyroidism were diagnosed in a majority of subjects relatively soon after the completion of therapy. Radiation dose to the hypothalamus in excess of 42 Gy was associated with an increase in the risk of developing TSH deficiency.

Abstract
INTRODUCTION Exposure to cancer and its treatments, including chemotherapy and radiotherapy, may result in late adverse effects including endocrine dysfunction. Endocrine disorders are the most commonly reported long-term complications of cancer treatment, especially by adult survivors of childhood cancers. This review will explore the endocrinologic adverse effects from non-endocrine cancer therapies. METHODS Searches including various Internet-based medical search engines such as PubMed, Medline Plus, and Google Scholar were conducted for published articles. RESULTS One hundred sixty-nine journal articles met the inclusion criteria. They included case reports, systematic analyses, and cohort reports. Endocrine disorders including hypothalamus dysfunction, hypopituitarism, syndrome of inappropriate anti-diuretic hormone secretion, diabetes insipidus, growth hormone disorders, hyperprolactinemia, gonadotropin deficiency, serum thyroid hormone-binding protein abnormalities, hypothyroidism, hyperthyroidism, hypomagnesium, hypocalcemia, hyperparathyroidism, hyperparathyroidism, adrenal dysfunction, gonadal dysfunction, hypertriglyceridemia, hypercholesterolemia, diabetes mellitus, and glycosuria were identified and their association with cancer therapies were outlined. DISCUSSION/CONCLUSIONS The journal articles have highlighted the association of cancer therapies, including chemotherapy and radiotherapy, with endocrine dysfunction. Some of the dysfunctions were more often experienced than others. Especially in patients treated with radiotherapy, some endocrinologic disorders were progressive in nature. IMPLICATIONS FOR CANCER SURVIVORS Recognition and awareness of endocrine sequelae of cancer treatments may permit for early detection and appropriate follow-up care for cancer survivors, thus improving their overall health and quality of life.

Abstract
Cranial irradiation is used in the management of a diverse group of intracranial pathologies. However, if any part of the hypothalamic-pituitary axis is included in the radiation field, there is a risk of developing neuroendocrine dysfunction. Growth hormone is the most radiosensitive of the anterior pituitary hormones, followed by the gonadotropins, adrenocorticotropic hormone and thyroid-stimulating hormone. A number of factors determine both the occurrence and severity of hypothalamic-pituitary dysfunction, including: the dose of radiation received by the hypothalamic-pituitary axis (determined by a number of factors including total dose and fractionation schedule and ultimately expressed as the biological effective dose); length of time since cranial irradiation; age of the patient at the time of cranial irradiation; type of radiotherapy administered; and the different inherent radiosensitivities of the anterior pituitary hormones. These neuroendocrine abnormalities usually develop a number of years after the initial insult and, therefore, patients who have received cranial irradiation should receive annual endocrine assessments. The establishment of endocrine late-effect clinics for the survivors of childhood cancers have gone some way to addressing this problem; however, other groups of patients, particularly those receiving cranial irradiation in adult life, may not have systematic endocrine assessment.

Abstract
BACKGROUND/AIMS The effects of growth hormone deficiency (GHD) on linear growth in children are well documented, but there is less convincing evidence regarding the impact on health-related quality of life (QOL). We examined QOL in children aged 8-16 years with acquired GHD following treatment for malignancy (AGHD) or idiopathic GHD (IGHD) on commencing growth hormone treatment (GHT) over 6 months. We adopted a longitudinal design involving consecutive patients and their families attending clinic over an 18-month period. Mothers and children were invited to complete questionnaires before GHT (T1) and 6 months later (T2). METHODS Mothers of 22 children (AGHD n = 14; IGHD n = 8) completed standardized measures of child QOL and behaviour. Children completed parallel measures of QOL, short-term memory tasks and fitness either in clinic or at the family home. RESULTS For children with AGHD, QOL was significantly below population norms at T1 and improved over time. For children diagnosed with IGHD, QOL at T1 was below, but comparable with population norms. QOL improved over time, though not significantly. CONCLUSION GHT is potentially valuable for improving QOL in children, especially in cases of AGHD. We conclude that benefits of GHT for QOL need to be evaluated independent of different diagnostic groups.

Abstract
CONTEXT Hypothalamic-pituitary (HP) dysfunction is common in children treated with cranial radiotherapy (RT) for brain tumors, but there is little known about the risk of HP dysfunction in adults treated with RT for primary nonpituitary brain tumors. OBJECTIVE The objective was to study the frequency of HP dysfunction in adults after RT for nonpituitary brain tumors. METHOD We studied 56 adult patients who received external beam RT for primary nonpituitary brain tumors at time intervals of 12-150 months after RT. The control group consisted of 20 RT-naive patients with primary brain tumors. GH and adrenal axes were assessed using the insulin tolerance test or the glucagon stimulation test. Gonadotroph, thyrotroph, and lactotroph function were assessed using baseline blood measurements. The biological effective dose (BED) to the HP axis was calculated in the RT patients. RESULTS Hypopituitarism was present in 41% of patients. The frequency of GH, ACTH, gonadotropin, and TSH deficiencies, and hyperprolactinemia was 32, 21, 27, 9, and 32%, respectively. Any degree of hypopituitarism and GH deficiency was significantly associated with longer time interval from RT and greater BED. However, gonadotropin deficiency and hyperprolactinemia were only related to BED, whereas ACTH deficiency was only significantly associated with the time interval from RT. One RT-naive patient was GH deficient. CONCLUSION Adult patients treated with cranial irradiation for primary nonpituitary brain tumors are at high risk of hypopituitarism, which is time and dose dependent. Long-term surveillance and periodic evaluation are needed. We recommend that adult late effect clinics, similar to those for children, should be established.

Abstract
BACKGROUND Adrenocorticotropin deficiency (ACTHD) can be clinically subtle, but life-threatening if not recognized. We assessed the prevalence of ACTHD in survivors of childhood cancer according to tumor diagnosis/therapy. PROCEDURE Chart review of endocrine/oncology history was performed in 310 childhood cancer survivors. Patients were referred to endocrine clinic because of slow growth, fatigue, or abnormal pubertal timing. Evaluation of growth hormone (GH), thyrotropin (TSH), ACTH, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) was performed. Low response to metyrapone and/or low dose ACTH test defined ACTHD. RESULTS ACTHD was identified in 56 (18%), [44 of 182 (24%) central nervous system (CNS) tumors, 3 of 18 (17%) non-CNS cranial tumors, 9 of 97 (9%) hematologic malignancies]. Of the 56 with ACTHD, 53 (95%) had received cranial irradiation (mean 45.5 Gy, range 14-70 Gy); three had not: one each with craniopharyngioma, hypothalamic astrocytoma, and brain stem glioma. All but one also had GH deficiency and/or central hypothyroidism. CONCLUSIONS Childhood cancer survivors with greatest risk for ACTHD had craniopharyngioma, other suprasellar tumor, or medulloblastoma or > or =24 Gy cranial irradiation. We recommend annual testing for ACTHD for 10-15 years and continued lifelong surveillance after CNS tumor or cranial irradiation, in patients with other hypothalamic-pituitary deficiencies or symptoms of ACTHD.

Abstract
Endocrinopathies are significant consequences of the treatment of childhood cancers. The risk of developing these adverse events is related to the underlying disease and its treatment with cytotoxic agents and radiation therapy. This article reviews hypothalamic-pituitary, thyroid, and gonadal dysfunction, as well as osteopenia-osteoporosis and obesity.

Abstract
The objectives of this study were 1) to compare final height and body mass index (BMI) between adult survivors of childhood brain cancer and age- and sex-matched population norms, 2) to quantify the effects of treatment- and cancer-related factors on the risk of final height below the 10th percentile (adult short stature) or having a BMI of 30 kg/m(2) or more (obesity). Treatment records were abstracted and surveys completed by 921 adults aged 20-45 yr who were treated for brain cancer as children and were participants in the multicenter Childhood Cancer Survivor Study. Nearly 40% of childhood brain cancer survivors were below the 10th percentile for height. The strongest risk factors for adult short stature were young age at diagnosis and radiation treatment involving the hypothalamic-pituitary axis (HPA). The multivariate odds ratio for adult short stature among those 4 yr of age or younger at diagnosis, relative to ages 10-20 yr, was 5.67 (95% confidence interval, 3.6-8.9). HPA radiation exposure increased the risk of adult short stature in a dose-response fashion (trend test, P < 0.0001). Adjuvant chemotherapy was not an independent risk factor for adult short stature. BMI distribution in survivors did not differ appreciably from that of population norms; however, in females, young age at diagnosis and HPA radiation dose (trend test, P < 0.001) were associated with risk of obesity. Except for patients treated with surgery only, survivors of childhood brain cancer are at very high risk for adult short stature, and this risk increases with radiation dose involving the HPA. We did not find a corresponding elevated risk for obesity.
