Abstract
BACKGROUND AND PURPOSE Obesity is a common yet incompletely understood complication of childhood craniopharyngioma. We hypothesized that craniopharyngioma is associated with specific defects in energy balance compared to obese control children. METHODS Eleven craniopharyngioma patients were recruited for a study on body composition and energy balance. Eight subjects were obese. The obese craniopharyngioma patients had a mean age (+/-SD) of 11.2 +/- 1.7 years. The average body mass index z score was 2.33 (+/-0.32). A previously studied group of obese children (BMI z score 2.46 +/- 0.46) served as controls. Resting energy expenditure (REE) was determined by indirect calorimetry and body composition by dual energy X-ray absorptiometry in all children. RESULTS Obese craniopharyngioma patient subjects had increased mean (+/-standard error) fat-free mass compared to obese controls (57% +/- 0.88 % vs 50.0% +/- 0.87%, p = 0.02). The obese craniopharyngioma patients had a 17% lower REE compared to values expected from the World Health Organization equation (1,541 +/- 112.6 vs 1,809 +/- 151.8 kcal; p = 0.01). In contrast, the obese control children had measured REE within 1% of predicted (1,647 +/- 33.2 vs. 1,652 +/- 40.2; p = 0.8). In a linear regression model, REE remained significantly lower than predicted after controlling for FFM. CONCLUSIONS Lower REE may be a factor contributing to obesity in children with craniopharyngioma. Further study is needed into the mechanisms for reduced energy expenditure in patients with craniopharyngioma.

Abstract
CONTEXT Retrospective studies suggest that adolescents with craniopharyngioma and hypothalamic obesity have increased sleep-disordered breathing (SDB). OBJECTIVES The objectives of this study were to compare the prevalence of SDB in adolescents with craniopharyngioma-related obesity compared with body mass index (BMI)-matched controls and to explore possible relationships between SDB, insulin resistance, and adipocytokines. DESIGN This was a cross-sectional study of obese craniopharyngioma and obese control adolescents. SETTING Subjects were evaluated in the clinical investigation unit at the Hospital for Sick Children, Toronto. PATIENTS Fifteen patients with craniopharyngioma-related obesity and 15 BMI-matched controls were recruited and tested. INTERVENTIONS Each subject underwent fasting blood work, frequent sampled iv glucose tolerance test, polysomnography, and abdominal magnetic resonance imaging with calculation of visceral and sc adipose tissue. MAIN OUTCOME MEASURES Main measures included insulin sensitivity, sleep efficiency, and fragmentation. RESULTS Insulin sensitivity was lower in craniopharyngioma subjects compared with control subjects (0.96 +/- 0.34 vs. 1.67 +/- 0.7, P = 0.01). Sleep-onset latency (19.3 +/- 27.8 vs. 31.9 +/- 23.4, P = 0.03) and oxygen saturations (rapid eye movement sleep: 89.0 +/- 5.1 vs. 94.2 +/- 2.3, P < 0.001; non-rapid eye movement sleep: 88.4 +/- 5.6 vs. 94.3 +/- 1.5, P < 0.001) were lower in craniopharyngioma. Obstructive apnea-hypopnea index (OAHI) (7.5 +/- 9.0 vs. 1.5 +/- 1.5, P = 0.03) was higher in craniopharyngioma. Respiratory distress index and OAHI correlated negatively with adiponectin concentrations (r = -0.61, P = 0.03, r = -0.71, P = 0.006, respectively) in craniopharyngioma. On multiple regression, TNF-alpha and craniopharyngioma were independent positive predictors of sleep-onset latency and adiponectin and craniopharyngioma were significant predictors (negative and positive, respectively) of OAHI. CONCLUSIONS SDB is increased in adolescents with craniopharyngioma-related obesity compared with BMI-matched controls. Routine polysomnography should be considered in obese patients with craniopharyngioma and appropriate treatment initiated.

Abstract
Craniopharyngioma (CP) is a pathologically benign tumor with high incidence of recurrence and poor prognosis. DNA ploidy, S-phase fraction (SPF), and G2 phase/mitosis phase + S phase (G2/M + S) measured by flow cytometry (FCM) have been shown to correlate with cell cycle characteristics and clinical prognosis of other tumors. By use of FCM and terminal deoxynucleotide transferase-mediated dUTP nick end labeling (TUNEL) peroxidase, we compared DNA content, SPF, G2/M + S, necrosis and apoptosis in non-recurrent and recurrent tumor cells of CP from 63 cases including 32 adamantine epitheliomas (AEs) and 31 squamous papillary tumors (SPTs), and the ultrastructure of the CP cell was observed by transmission electron microscopy. Although no obvious differences between DNA content and necrosis and apoptosis rate were observed in subgroups of CPs, SPF and G2/M + S for recurrent tumors were statistically higher than those for recurrence-free tumors, and the recurrence rate of AE tumors is higher than that of SPT. Therefore, CP cells are diploid, and SPF and G2/M + S are related to recurrence of CP.

Abstract
INTRODUCTION Multimodal treatment in the management of giant craniopharyngiomas (>4 cm in diameter) is necessary to obtain optimal results, and includes conservative or palliative treatment and "aggressive" removal. The significance of a new treatment algorithm including direct surgical resection with the intent to avoid radiation therapy and regrowth will be discussed here. MATERIALS AND METHODS Between January 1996 and January 2005 16 patients were diagnosed with giant craniopharyngiomas. Two of them underwent only cyst aspiration because of their advanced age and/or lack of improvement of neuropsychological deficits. One patient underwent transsphenoidal operation and in the remaining 13 transcranial surgery was performed. Four additional patients underwent surgery for recurrence. The prospective protocol included pre- and post-operative dynamic endocrine tests, high field 1.5 T MRI and ophthalmological as well as neuropsychological examinations. RESULTS In resectable tumours, the rate of total removal was ten out of 12 with two recurrences. In the remaining two patients with recurrences this intention was abandoned because of a firm tumour or a deteriorating neuropsychological status prior to the scheduled additional operation. There was no mortality and the morbidity rate was 6.3%. Visual function improved in 11, was unchanged in one and deteriorated in two patients. Secretion of different adenohypophyseal hormones deteriorated after tumour resection in one to three patients, and new diabetes insipidus occurred in six patients. There was no permanent deterioration of neuropsychological function. CONCLUSION Special reference is given to direct resection of tumours at an optimal timing within this management. If hypothalamic disturbances are absent or improving due to pre-treatment (medical therapy, symptomatic surgery), giant craniopharyngiomas can be surgically removed in more than two of three patients with low morbidity and only moderate deterioration of endocrine function. The latter has to be accepted when curative surgery is intended, but even then, recurrences cannot be prevented. Contraindication for curative surgery is persisting hypothalamic damage necessitating conservative treatment modalities.

Abstract
OBJECTIVE Adults patients previously treated for craniopharyngioma have increased general and physical fatigue compared to healthy controls. This could be related to disturbed sleep patterns. The aim of this study was to compare sleepiness and sleep patterns in those patients to healthy controls and to patients treated for nonfunctioning macroadenomas (NFMA) of the pituitary. DESIGN Case-control study. PATIENTS AND METHODS Sleepiness and sleep patterns were assessed in 27 adult patients [14 men, 8 patients diagnosed at childhood age, mean age of 53 years (range 27-80 year)] after long-term follow-up and compared to 50 healthy controls and 38 age-, gender- and BMI-matched patients with NFMA. We used two validated questionnaires for sleep parameters (Epworth sleepiness score and Münchener Chronotype Questionnaire). RESULTS Sleep patterns (onset, sleep timing, duration and rise time) were not statistically different between the three groups. However, daytime sleepiness scores were increased in patients treated for craniopharyngioma compared to healthy controls, but not different from patients with NFMA. Thirty-three percent of patients with craniopharyngiomas had ESS scores above 10 compared to 8% of healthy controls (P = 0.005), indicating severe daytime hypersomnolence. Neither type of surgery, previous radiotherapy, or age at diagnosis influenced the sleepiness scores in patients with craniopharyngioma. CONCLUSION Patients treated for craniopharyngioma or NFMA have increased daytime somnolence despite normal sleep patterns, compared to healthy subjects. The results indicate that increased daytime somnolence is a general consequence of large tumours, and/or their treatment, in the hypothalamic/pituitary region, rather than a specific feature of craniopharyngiomas per se.

Abstract
In this study, we attempted to determine if different locations of a tumor influence the hypothalamopituitary axis function and outcomes with childhood craniopharyngiomas. The preoperative, postoperative, and long-term follow-up endocrinological disturbances of 66 children with a craniopharyngioma were retrospectively studied. The patients were divided into two subgroups according to the location of the tumor (intrasellar and third ventricle floor). The mean age at onset was 8.02 (range, 1.42-17.58)years. These patients were followed-up for a median duration of 7.2 (range, 2-22)years. Vision problems as the first symptom were more common in Group One (with intrasellar tumors) compared to Group Two (55.6% vs 15.4%; p=0.001; Fisher's exact test). Increased intracranial pressure was the most common initial symptom in patients in Group Two (51.3%) and the second most common symptom in Group One (37%). The majority of patients in both Group One and Group Two required some forms of pituitary hormone supplements (96% vs 84%). At the last follow-up, more patients with intrasellar craniopharyngiomas needed cortisone supplements (79.2% in Group One vs 45.9% in Group Two; p=0.016; Fisher's exact test); however, children with third ventricle floor tumors had more prevalent weight gain (4.2% in Group One vs 27.0% in Group Two; p=0.038; Fisher's exact test). There were different initial presentations and endocrinological outcomes between children with intrasellar and third ventricle floor craniopharyngiomas. The intrasellar tumors had greater pituitary hormone disturbance. However, at the long-term follow-up, children with third ventricle floor tumors had a greater prevalence of being overweight and obese, which was associated with hypothalamic dysfunction.

Abstract
The patient is a 44-year-old man who underwent resection of a posterior nasopharynx tumor 12 years earlier via left lateral rhinotomy approach. The final pathological analysis indicated the tumor was a craniopharyngioma, and the patient subsequently underwent focal radiation. The patient returned to medical attention complaining of dysequilibrium. A neurologic exam was nonfocal. Magnetic resonance imaging revealed a clival mass, separate from the sella turcica, with imaging characteristics concerning for chordoma or primary bone tumor (Fig. 1). The lesion was resected via an endoscope-assisted endonasal transsphenoidal approach, with gross total resection achieved. Intraoperatively, the mass was noted to erode through the posterior nasopharynx, without extension superiorly into the sella or posteriorly through the clival dura (i.e., lesion was infrasellar). The final pathological results indicated the tumor was adamantinomatous craniopharyngioma.

Abstract
BACKGROUND Craniopharyngioma is a rare, benign epithelial brain tumor of the suprasellar region with a high rate of recurrence. Clinical and histopathological features that might be predictors of recurrence/regrowth have not been clearly delineated. METHODS We compared recurrence/regrowth of the tumors with the clinico-pathological characteristics, vascular density, cell proliferation index, and immunohistochemical profile (cytokeratins, epithelial membrane antigen [EMA], carcinoembrionary antigen [CEA], and laminin) of 47 patients with craniopharyngioma followed for more than 5 years. RESULTS Tumors were adamantinomatous in 42 cases (89%) and papillary squamous in 5 cases (11%). Immunoreactivity for cytokeratin 8/18/19 was positive in 64%; cytokeratin 5 in 42%; laminin 8 in 62%; and CEA in 21%. The cell proliferation index and vascular density were greater in adamantinomatous than in papillary tumors (22+/-6 versus 17+/-3, p=0.05; and 21+/-3 versus 17+/-3, p=0.037, respectively); they were neither related to recurrence nor to regrowth. No significant differences were found between adamantinomatous and papillary tumors regarding the presence of cytokeratin, laminin, CEA or glial fibrillary acidic protein (GFAP). Recurrence rate at 5 years was 59%. No relation was found between recurrence and adjuvant radiotherapy (AR). Residual tumor after surgery, whorl-like arrays (p=0.04) and immunoreactivity for p53 (p=0.022) were significantly related to recurrence/regrowth. CONCLUSIONS Residual tumor after surgery, immunoreactivity to p53 and presence of whorl-like arrays are associated to recurrence/regrowth of craniopharyngioma.

Abstract
OBJECTIVE The restricted radiation tolerance of the anterior visual pathways represents a unique challenge for ablating adjacent lesions with single-session radiosurgery. Although preliminary studies have recently demonstrated that multisession radiosurgery for selected perioptic tumors is both safe and effective, the number of patients in these clinical series was modest and the length of follow-up limited. The current retrospective study is intended to help address these shortcomings. METHODS Forty-nine consecutive patients with meningioma (n = 27), pituitary adenoma (n = 19), craniopharyngioma (n = 2), or mixed germ cell tumor (n = 1) situated within 2 mm of a "short segment" of the optic apparatus underwent multisession image-guided radiosurgery at Stanford University Medical Center. Thirty-nine of these patients had previous subtotal surgical resection, and six had previously been treated with conventional fractionated radiotherapy (6). CyberKnife radiosurgery was delivered in two to five sessions to an average tumor volume of 7.7 cm3 and a cumulative average marginal dose of 20.3 Gy. Formal visual testing and clinical examinations were performed before treatment and at follow-up intervals beginning at 6 months. RESULTS After a mean visual field follow-up of 49 months (range, 6-96 mo), vision was unchanged postradiosurgery in 38 patients, improved in eight (16%), and worse in three (6%). In each instance, visual deterioration was accompanied by tumor progression that ultimately resulted in patient death. However, one of these patients, who had a multiply recurrent adrenocorticotropic hormone-secreting pituitary adenoma, initially experienced early visual loss without significant tumor progression after both a previous course of radiotherapy and three separate sessions of radiosurgery. After a mean magnetic resonance imaging follow-up period of 46 months, tumor volume was stable or smaller in all other cases. Two patients died of unrelated nonbrain causes. CONCLUSION Multisession radiosurgery resulted in high rates of tumor control and preservation of visual function in this group of perioptic tumors. Ninety-four percent of patients retained or improved preradiosurgical vision. This intermediate-term experience reinforces the findings from earlier studies that suggested that multisession radiosurgery can be a safe and effective alternative to either surgery or fractionated radiotherapy for selected lesions immediately adjacent to short segments of the optic apparatus.

Abstract
OBJECTIVE The endoscope has recently been applied to the supradiaphragmatic transsphenoidal approach, but only case reports dealing with different pathological features have been described. The authors present their experience with this technique in 10 patients with craniopharyngiomas. METHODS A pure endoscopic endonasal technique was used. From November 1998 through May 2005, four males and six females with a craniopharyngioma, either purely supradiaphragmatic (six patients) or with a significant suprasellar component (four patients), were treated. The tumors had a mean diameter of 2.9 cm (range, 1-4 cm); four patients had a major prechiasmatic component and six had a retrochiasmatic one. RESULTS Seven total, one subtotal, and two partial resections were obtained. Vision symptoms improved significantly in six out of eight patients. Endocrine function did not improve after surgery, and diabetes insipidus was the most frequent deficit, although it was transient in five out of eight patients. Cerebrospinal fluid leak was the most frequent complication and required reoperation in two patients. Postoperative obesity occurred in two patients. No recurrence has yet been documented in the total resection group. The mean follow-up period is 37 months (range, 3-75 mo). CONCLUSION The endoscopic technique allows results comparable with the best microscopic series. We think that this technique increases the safety of the procedure because of improved vision. Further studies are required to better define the exact location of the tumor with respect to the arachnoidal plane, the extra-arachnoidal craniopharyngioma being the most suitable for a radical removal using a transsphenoidal supradiaphragmatic approach.

Abstract
The novel PTCH mutation and clinical manifestations within Gorlin syndrome family links PTCH haploinsufficiency and aberrant activation of the Wnt pathway. We report a family case with Gorlin syndrome, characterized by the usual phenotype features such as widespread basocellular tumors and craniofacial and bone malformations, but also including a less common appearance of craniopharyngioma. These clinical manifestations might be associated with a novel constitutional mutation of the PTCH gene, 1047insAGAA, which we found in exon 7. It changes the normal amino acid sequence leading to termination of the PTCH protein at exon 9. The analyzed tumors of the family show extensive loss of heterozygosity in the PTCH region, both basocellular and in particular craniopharyngioma, and in the latter a high expression of beta-catenin was detected. Our findings suggest involvement of the SHH/PTCH/SMO pathway in pathogenesis of the analyzed disorders, including its possible contribution to aberrant activation of the Wnt pathway in craniopharyngioma.

Abstract
In summary, much progress has been made in our understanding of childhood craniopharyngiomas. These histologically benign but "geographically malignant" tumors are challenging to treat and require experienced clinicians from multiple disciplines including neurosurgery, radiology, hematology/oncology, ophthalmology, endocrinology, and general pediatrics to address the multiple issues that arise with diagnosis, treatment, and long-term follow-up of affected children. The study and close observation of patients who have craniopharyngiomas may also be beneficial for our general understanding of pathophysiologic processes such as the observed "growth without growth hormone" phenomenon or the well-described and studied hypothalamic obesity phenotypes.

Abstract
The mechanism of spontaneous resolution of diabetes insipidus (DI) was investigated after surgery for large craniopharyngioma. Twenty-two adult patients (mean age 48.9 years old), who underwent surgery via the anterior interhemispheric trans-lamina terminalis approach, were divided into three groups: Group I, the entire pituitary stalk was preserved (n = 2); Group II, the stalk was dissected distally from the tumor but ultimately sacrificed (n = 9); Group III, the stalk was not identified and was sacrificed (n = 11). All patients were discharged without neurological deficits 1 month after surgery. Four patients underwent gamma-knife treatment for residual tumor or recurrence. Postoperative endocrinological functions were normal in Group I, and no replacement therapy was required. Hormonal replacement for pan-hypopituitarism and DI was necessary in Groups II and III (mean follow-up period 5.9 years). DI resolved at 2.7 +/- 1.3 years after surgery in four patients in Group II, and a hypertonic saline infusion test revealed production of small amounts of intrinsic antidiuretic hormone (ADH). Urine osmolarity was high in the morning, and a significant increase in urinary osmolarity was noted after Pitressin injection. These results indicate induction of hypersensitivity of the distal renal tubules to small amounts of intrinsic ADH, resulting in decreased urinary output. Recovery from DI can be expected, despite permanent impairment of anterior pituitary function, if the pituitary stalk is dissected as distally as possible.

Abstract
Central diabetes insipidus developed for the first time in a 14-year-old female during the resection of a craniopharyngioma. The water diuresis persisted until a vasopressin analogue (dDAVP) was given. Professor McCance was asked to explain why hypernatraemia developed, to anticipate dangers that might develop in the salt and water area with therapy, and to provide insights into why this patient died, due to the subsequent development of hyponatraemia that caused a lethal rise in intracranial pressure. The team specifically wanted Professor McCance's opinions as to why a PNa of 124 mmol/l was uniquely dangerous for this patient, and this was a particularly challenging conundrum. Nevertheless, with the aid of a mini-experiment, a careful chart review, and creative thinking, he was able to offer a novel solution, and to suggest ways to prevent its occurrence in other patients.

Abstract
Craniopharyngiomas are benign suprasellar tumors that arise from epithelial remnants of the Rathke's pouch. The two standard treatment options are primary total resection or limited surgery followed by external beam radiation. The 10- and 20-year progression-free survival rates following limited surgery and radiation therapy are superior to those achieved by primary surgery alone. The side effect profiles for these two treatment approaches are different. Following total resection there is a very high incidence of panhypopituitarism requiring lifelong multiple hormone replacement therapy. The other side effects include potential damage to adjacent structures such as optic chiasm, vasculature and hypothalamus. Following limited surgery and radiation therapy the incidence of endocrine deficits is significantly lower compared to radical surgery, as is the risk of neurovascular and hypothalamic injury. Optic neuropathy and brain necrosis are rare in modern radiation therapy series. Second malignant neoplasms, although rare, can occur. In children with recurrent craniopharyngiomas following radical surgery, the recommended salvage treatment is radiation therapy, as further surgical attempts at salvage are associated with high relapse rates and increased morbidity and mortality. There have been significant technological advances in the field of radiation treatment planning and delivery that have great potential for reducing the incidence of long-term irradiation sequelae in the developing brain. The general availability of megavoltage linear accelerators and modern radiotherapy innovations such as three-dimensional conformal radiation treatment (3D CRT), stereotactic radiosurgery (SRS), stereotactic radiotherapy (SRT), and intensity modulated radiation therapy (IMRT) should further limit the rate of complications and improve cure rates in children with primary or recurrent craniopharyngioma.

Abstract
BACKGROUND A prospective study on childhood craniopharyngiomas (CPs) was conducted from 1994 to 1998 to appreciate the pre- and postoperative clinical, endocrine, mental, and intellectual status of the patients and to determine the incidence and severity of the postoperative hypothalamic syndrome. METHODS The series included 14 consecutive CPs. Twelve were retrochiasmatic and intraventricular, and two were partly prechiasmatic and extraventricular. All were treated with the aim of "total" removal. The removal was "total" in nine cases but incomplete in the other five. Immediate postoperative follow-up was uncomplicated in all cases. CONCLUSION At 2-year follow-up, the two children with an extraventricular CP and a "total" tumor removal were intellectually normal, had no hypothalamic syndrome, and attended normal school with good results. The 12 others, although still intellectually normal, were more or less severely affected by a hypothalamic syndrome which altered their social insertion and caused academic failure. The authors conclude from this study that radical surgery should be reserved to extraventricular CPs only.

Abstract
RATIONALE Due to the proximity of craniopharyngiomas to the hypothalamus and pituitary gland, most children and adolescents presenting with these tumors will exhibit significant endocrine dysfunction. After treatment, these impairments can become a major cause of morbidity and mortality. METHODS The postoperative course of children undergoing surgery for craniopharyngioma is reviewed. CONCLUSION Even if hormone levels seem to be adequate in the short term after treatment, deficiencies may develop over years and need to be monitored closely.

Abstract
OBJECTIVES In 1996 we published our results for treatment of childhood craniopharyngioma. That study did not only reveal that there was a significant morbidity associated with our then policy of attempted radical removal followed by post-operative radiotherapy in those cases with residual disease, but also that risk factors for poor outcome could be identified based on the clinical and radiological findings at presentation. As result of that study, we redefined the role of radical surgery in the treatment of craniopharyngioma and developed a new treatment strategy in an attempt to improve the quality of outcome without compromising tumour control. Our aims in this paper were to compare the results of our current treatment strategy with that reported in the 1996 paper to assess whether we have achieved this goal. METHODS A detailed assessment of the treatment pathway and outcome was undertaken for children treated for craniopharyngioma in our unit from 1996 to 2004. This included a morbidity score based on visual, motor, cognitive, hypothalamic and endocrinological data obtained from our neuro-oncology database and review of clinical records. Where possible we have attempted to record data in the same manner as for our previous study allowing for meaningful comparison. RESULTS Forty-eight children with craniopharyngioma presented in the study period. On the basis of clinical presentation and radiological findings, 25 were deemed suitable for attempted radical surgery and 23 were treated with various subtotal surgical procedures. Radiotherapy was used in patients over the age of 5 years where residual tumour was present or progressed after the initial surgical intervention(s). Morbidity scores, particularly in relation to visual and cognitive outcome, are improved and there was no surgical mortality in the current series. CONCLUSIONS A treatment paradigm for childhood craniopharyngioma is presented which improves the quality of outcome without compromising tumour control.

Abstract
RATIONALE We analyzed the impact of tumour localization and histology on functional capacity (FC) and body mass index (BMI) in children with sellar masses. METHODS FC was evaluated using the ability scale Fertigkeitenskala Münster-Heidelberg in 403 children and adolescents with sellar masses (276 craniopharyngioma, 14 germinoma, 21 optic/chiasmatic glioma, 40 hypothalamic glioma, 13 cysts of Rathke's cleft and 39 other sellar masses). Besides tumour localization, the influence of gender, irradiation and age at diagnosis and at evaluation on FC and BMI was analyzed. General linear models with explanatory influential variables were built. RESULTS In multivariate analysis, only age at diagnosis (p<0.001) and hypothalamic involvement (p=0.005) had relevant impact on FC. The second model showed BMI at diagnosis (p<0,001), hypothalamic involvement (p<0.001) and craniopharyngioma (p=0,004) to influence BMI at the latest evaluation. CONCLUSION We conclude that hypothalamic involvement and young age at diagnosis had major impact on FC and BMI and should be considered as risk factors for impaired rehabilitation.

Abstract
BACKGROUND Craniopharyngioma is a parasellar tumour that, although benign, tends to behave aggressively. It can occur at any age but most commonly presents in childhood or adolescence. OBJECTIVES To investigate the frequency and severity of problems associated with craniopharyngioma, using the large international database (KIMS) for adult patients with GH deficiency (GHD), and to assess the differences between the adult onset (AO, aged 18 or above) disease and adults with childhood onset (CO) craniopharyngioma. DESIGN Inclusion criteria were: an established diagnosis of craniopharyngioma, severe GHD and no recent GH treatment. These criteria were fulfilled by 393 (184 female, 209 male) patients; 241 had AO (mean age 28.7 +/- 8.7 years) and 152 had CO disease (age 42.0 +/- 12.3 years). Disease history, clinical features and anthropometric data were recorded at the time of enrolment in the database, and body composition, serum IGF-I, serum lipids and quality of life (QoL) were assessed. RESULTS Peak age at onset of craniopharyngioma was 15-20 years. Ninety percent of patients had been treated surgically. CO patients were shorter than AO patients and had much lower IGF-I standard deviation scores (SDS). The majority had hypopituitarism and over 60% had diabetes insipidus. Body mass index (BMI) was higher in AO males (30.2 +/- 5.5) than in CO males (28.5 +/- 7.5); waist circumference was also greater. Obesity was more common in AO patients (51.8% vs 39.1%). Body composition did not differ between groups. Cholesterol and triglycerides were higher in AO than in CO patients, but high density lipoprotein (HDL)- and low density lipoprotein (LDL)-cholesterol did not differ. Quality of life, assessed by Quality of Life-Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA) and the Nottingham Health Profile, was markedly reduced in all groups with no significant differences between them; the QoL-AGHDA score correlated with age at onset of both craniopharyngioma and GHD, and also with BMI in AO patients. CONCLUSIONS These data emphasise the generally poor state of health of patients treated for craniopharyngioma, with respect to endocrine and metabolic function, and also the markedly reduced quality of life. In addition to GHD, most patients have evidence of hypothalamic damage with associated obesity, diabetes insipidus and hypopituitarism. Adults with CO craniopharyngioma were shorter, had lower IGF-I, lower BMI, less obesity and slightly lower blood lipid levels than patients with AO craniopharyngioma.

Abstract
Extreme degrees of obesity may occur in association with hypothalamic tumors, usually after surgical intervention. This phenomenon has been reported to occur in as many as 25-75% of children undergoing extensive surgical extirpation of craniopharyngiomas (Cranio). Because less is known about the auxology of children with Cranio with milder alterations in growth, we undertook a 3-yr longitudinal analysis, using the KIGS database (Pfizer International Growth Database), to study their growth patterns and evolution of weight. We compared the effect of GH therapy on height, weight, and body mass index (BMI) in 199 prepubertal children with diagnosed Cranio treated by surgery and/or radiotherapy to two other groups of children with other causes of organic GH deficiency (OGHD): one with postsurgical and/or postirradiated OGHD (OGHD + S/I; n = 92) and the other with OGHD not due to Cranio and not having undergone either surgery or irradiation (OGHD - S/I; n = 85). At the start of GH therapy, 1) mean chronological (P < 0.0001) and bone (P = 0.0002) ages were youngest in OGHD - S/I and oldest in OGHD + S/I; 2) the mean height sd score (SDS) was lowest in OGHD - S/I and comparably higher in the other two groups (P < 0.0001); 3) mean weight and BMI SDS were greatest in Cranio and least in OGHD - S/I (both P < 0.0001); and 4) the mean initial GH dose prescribed was highest in OGHD - S/I and comparable in the other two groups (P < 0.0001). After 3 yr of GH therapy, 1) mean bone age remained youngest in OGHD - S/I and oldest in OGHD + S/I (P < 0.0001); 2) mean height SDS was highest in Cranio and comparably lower in the other two groups (P = 0.0159); 3) mean weight and BMI SDS remained greatest in Cranio and least in OGHD - S/I (P < 0.0001 and P = 0.0003, respectively); and 4) the mean GH dose remained highest in the OGHD - S/I group and least in the Cranio group (P = 0.0082). There were statistically significant increases within each group between the start of treatment and after 3 yr of GH therapy in height and weight, but not in BMI SDS. Lastly, after 3 yr of GH treatment, children in the Cranio group continued to have disproportionately heavier weight and higher BMI (with the greatest values in those with lower stimulated peak GH concentrations) compared with members of the other two groups, with no salutary effect of GH treatment on weight SDS and a mild improvement in BMI SDS. After S/I treatment, children with Cranio are disproportionately prone to varying degrees of weight gain compared with children with other forms of OGHD. In the present cohort of prepubertal children with Cranio, GH therapy induced excellent linear growth, but failed to have an ameliorative effect on weight gain and had only a slight beneficial effect on BMI gain. Because affected children may have resultant significant long-term medical morbidity and diminished quality of life, it is critical that the mechanism of this phenomenon be determined to devise helpful preventive or therapeutic interventions.

Abstract
OBJECTIVE In this study we aimed to establish the frequency of postoperative diabetes insipidus and the incidence and characteristics of abnormalities of thirst in a cohort of patients with craniopharyngioma, in whom neurosurgery had been performed. DESIGN Diabetes insipidus was determined by either standard criteria for diagnosis in the immediate postoperative period, or by water deprivation test, in all craniopharyngioma and pituitary tumour patients who underwent surgery in Beaumont Hospital between the years 1986 and 1998. Osmoregulated thirst and vasopressin release were studied during a 2-h infusion of hypertonic (5%) saline followed by a 30-min period of free access to water. PATIENTS Data on the incidence of postoperative diabetes insipidus was collected in 26 patients with craniopharyngioma and 154 patients with pituitary adenomata. We recruited 16 healthy control patients, 16 patients with cranial diabetes insipidus following pituitary tumour surgery and 16 patients with cranial diabetes insipidus following craniopharyngioma resection for the hypertonic saline infusion study. RESULTS Twenty-five patients out of 26 (96%) patients developed diabetes insipidus after surgery for craniopharyngioma, a much higher incidence than after surgery for suprasellar (26/88, 30%, P < 0.001) or intrasellar pituitary tumours (9/66, 14%, P < 0.001). Hypertonic saline infusion identified abnormal thirst responses in five of the 16 craniopharygioma patients studied; all of the pituitary tumour patients had a normal thirst response. Three of the craniopharyngioma patients had adipsic diabetes insipidus whilst two had polydipsic diabetes insipidus. CONCLUSION This study demonstrates following surgery for craniopharyngioma there is a high incidence of cranial diabetes insipidus and a significant incidence of abnormal thirst responses to osmotic stimuli.
