- Patients with childhood, adolescent, and young adult cancer who will be treated with gonadotoxic therapies are at increased risk for infertility. Many patients and their families desire biological children but effective communication about treatment-related infertility risk and procedures for fertility preservation does not always happen. The PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the literature and developed a clinical practice guideline that provides recommendations for ongoing communication methods for fertility preservation for patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger and their families. Moreover, the guideline panel formulated considerations of the ethical implications that are associated with these procedures. Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the evidence and recommendations. In this clinical practice guideline, existing evidence and international expertise are combined to develop transparent recommendations that are easy to use to facilitate ongoing communication between health-care providers and patients with childhood, adolescent, and young adult cancer who might be at high risk for fertility impairment and their families.

- Childhood, adolescent, and young adult cancer survivors are at increased risk of reduced bone mineral density. Clinical practice surveillance guidelines are important for timely diagnosis and treatment of these survivors, which could improve bone mineral density parameters and prevent fragility fractures. Discordances across current late effects guidelines necessitated international harmonisation of recommendations for bone mineral density surveillance. The International Late Effects of Childhood Cancer Guideline Harmonization Group therefore established a panel of 36 experts from ten countries, representing a range of relevant medical specialties. The evidence of risk factors for very low and low bone mineral density and fractures, surveillance modality, timing of bone mineral density surveillance, and treatment of very low and low bone mineral density were evaluated and critically appraised, and harmonised recommendations for childhood, adolescent, and young adult cancer survivors were formulated. We graded the recommendations based on the quality of evidence and balance between potential benefits and harms. Bone mineral density surveillance is recommended for survivors treated with cranial or craniospinal radiotherapy and is reasonable for survivors treated with total body irradiation. Due to insufficient evidence, no recommendation can be formulated for or against bone mineral density surveillance for survivors treated with corticosteroids. This surveillance decision should be made by the survivor and health-care provider together, after careful consideration of the potential harms and benefits and additional risk factors. We recommend to carry out bone mineral density surveillance using dualenergy x-ray absorptiometry at entry into long-term follow-up, and if normal (Z-score > -1), repeat when the survivor is aged 25 years. Between these measurements and thereafter, surveillance should be done as clinically indicated. These recommendations facilitate evidence-based care for childhood, adolescent, and young adult cancer survivors internationally.

- Treatment with chemotherapy, radiotherapy, or surgery that involves reproductive organs can cause impaired spermatogenesis, testosterone deficiency, and physical sexual dysfunction in male pubertal, adolescent, and young adult cancer survivors. Guidelines for surveillance and management of potential adverse effects could improve cancer survivors' health and quality of life. Surveillance recommendations vary considerably, causing uncertainty about optimum screening practices. This clinical practice guideline recommended by the International Late Effects of Childhood Cancer Guideline Harmonization Group in collaboration with the PanCareSurFup Consortium, developed using evidence-based methodology, critically synthesises surveillance recommendations for gonadotoxicity in male childhood, adolescent, and young adult (CAYA) cancer survivors. The recommendations were developed by an international multidisciplinary panel including 25 experts in relevant medical specialties, using a consistent and transparent process. Recommendations were graded according to the strength of underlying evidence and potential benefit gained by early detection and appropriate management. The aim of the recommendations is to enhance evidence-based care for male CAYA cancer survivors. The guidelines reveal the paucity of high-quality evidence, highlighting the need for further targeted research.

- Purpose: Female survivors of childhood, adolescent, and young adult (CAYA) cancer who were treated with alkylating agents and/or radiation, with potential exposure of the ovaries, have an increased risk of premature ovarian insufficiency (POI). Clinical practice guidelines can facilitate these survivors' access to optimal treatment of late effects that may improve health and quality of survival; however, surveillance recommendations vary among the existing long-term follow-up guidelines, which impedes the implementation of screening. Patients and Methods: The present guideline was developed by using an evidence-based approach and summarizes harmonized POI surveillance recommendations for female survivors of CAYA cancer who were diagnosed at age < 25 years. The recommendations were formulated by an international multidisciplinary panel and graded according to the strength of the evidence and the potential benefit gained from early detection and intervention. The harmonized POI surveillance recommendations were developed by using a transparent process and are intended to facilitate care for survivors of CAYA cancer. Results and Conclusion: The harmonized set of POI surveillance recommendations is intended to be scientifically rigorous, to positively influence health outcomes, and to facilitate the care for female survivors of CAYA cancer.

- Patients with craniopharyngioma suffer from obesity and impaired bone health. Little is known about longitudinal changes in body composition and bone mineral density (BMD).To describe body composition and BMD (change).Retrospective longitudinal study.Two Dutch/Swedish referral centers.Patients with craniopharyngioma (n=112) with a DXA-scan available [two DXA-scans, n=86; median Δtime 9.6 years (range 0.4-23.3)] at age ≥18 years [58 (52%) male, 50 (44%) childhood-onset].Longitudinal changes of body composition and BMD, and associated factors of ΔZ-score (sex and age standardized).BMI (from 28.8±4.9 to 31.2±5.2 kg/m 2, P<0.001), fat mass index (FMI) (from 10.5±3.6 to 11.9±3.8 kg/m 2, P=0.001) and fat free mass index (FFMI) (from 18.3±3.2 to 19.1±3.2 kg/m 2, P<0.001) were high at baseline and increased. Fat percentage and Z-scores of body composition did not increase, except for FFMI Z-scores (from 0.26±1.62 to 1.06±2.22, P<0.001). Z-scores of total body, L2-L4, femur neck increased (mean difference 0.66±1.00, P<0.001; 0.78±1.63, P<0.001; 0.51±1.85, P=0.02). Linear regression models for ΔZ-score were positively associated with growth hormone replacement therapy (GHRT) [femur neck: beta 1.45 (95% CI 0.51-2.39)]; and negatively with radiotherapy [femur neck: beta -0.79 (-1.49--0.09)], glucocorticoid dose [total body: beta -0.06 (-0.09--0.02)]) and medication to improve BMD [L2-L4: beta -1.06 (-1.84--0.28)]).Z-scores of BMI, fat percentage and FMI remained stable in patients with craniopharyngioma over time, while Z-scores of FFMI and BMD increased. Higher glucocorticoid dose and radiotherapy were associated with BMD loss and GHRT with increase.

Tidskriftsartikel (refereegranskat)abstract
- Craniopharyngioma patients often have poor metabolic profiles due to hypothalamic-pituitary damage. Previously, using body mass index (BMI) as obesity marker, the occurrence of the metabolic syndrome in these patients was estimated at 46%. Our aim was to determine if Dual X-ray Absorptiometry (DXA-) scan in evaluation of obesity and metabolic syndrome would be superior.Retrospective study of craniopharyngioma patients for whom DXA-scan results were available.BMI, fat percentage and fat mass index were used to evaluate obesity and as components for obesity in metabolic syndrome.Ninety-five craniopharyngioma patients were included (51% female, 49% childhood-onset disease). Metabolic syndrome occurred in 34-53 (45-51%) subjects (depending on the definition of obesity, although all definitions occurred in higher frequency than in the general population). Metabolic syndrome frequency was higher if obesity was defined by fat percentage (52% vs. 42%) or fat mass index (51% vs. 43%) compared to BMI. Misclassification appeared in 9% (fat percentage vs. BMI) and 7% (fat mass index vs. BMI) for metabolic syndrome and 29% and 13% for obesity itself, respectively. For metabolic syndrome, almost perfect agreement was found for BMI compared with fat percentage or fat mass index. For obesity, agreement was fair to moderate (BMI vs. fat percentage).Using BMI to evaluate obesity underestimates the true prevalence of metabolic syndrome in patients with craniopharyngioma. Furthermore, fat percentage contributes to a better evaluation of obesity than BMI. The contribution of DXA-scan might be limited for identification of the metabolic syndrome.

- Most studies in patients with craniopharyngioma did not investigate morbidity and mortality relative to the general population nor evaluated risk factors for excess morbidity and mortality. Therefore, the objective of this study was to examine excess morbidity and mortality, as well as their determinants in patients with craniopharyngioma.Hospital-based retrospective cohort study conducted between 1987 and 2014.We included 144 Dutch and 80 Swedish patients with craniopharyngioma identified by a computer-based search in the medical records (105 females (47%), 112 patients with childhood-onset craniopharyngioma (50%), 3153 person-years of follow-up). Excess morbidity and mortality were analysed using standardized incidence and mortality ratios (SIRs and SMRs). Risk factors were evaluated univariably by comparing SIRs and SMRs between non-overlapping subgroups.Patients with craniopharyngioma experienced excess morbidity due to type 2 diabetes mellitus (T2DM) (SIR: 4.4, 95% confidence interval (CI): 2.8-6.8) and cerebral infarction (SIR: 4.9, 95% CI: 3.1-8.0) compared to the general population. Risks for malignant neoplasms, myocardial infarctions and fractures were not increased. Patients with craniopharyngioma also had excessive total mortality (SMR: 2.7, 95% CI: 2.0-3.8), and mortality due to circulatory (SMR: 2.3, 95% CI: 1.1-4.5) and respiratory (SMR: 6.0, 95% CI: 2.5-14.5) diseases. Female sex, childhood-onset craniopharyngioma, hydrocephalus and tumour recurrence were identified as risk factors for excess T2DM, cerebral infarction and total mortality.Patients with craniopharyngioma are at an increased risk for T2DM, cerebral infarction, total mortality and mortality due to circulatory and respiratory diseases. Female sex, childhood-onset craniopharyngioma, hydrocephalus and tumour recurrence are important risk factors.

- Craniopharyngioma is a sellar tumor associated with high rates of pituitary deficiencies (~98%) and hypothalamic obesity (~50%).To determine the efficacy regarding long-term weight loss after bariatric surgery in obese craniopharyngioma patients with hypothalamic dysfunction.Retrospective case control study.Multicenter international study.Obese craniopharyngioma patients (N = 16; of which 12 women) with a history of bariatric surgery [12 Roux-en-Y gastric bypass, 4 sleeve gastrectomy; median age of 21 years (range 15-52), median follow-up 5.2 years (range 2.0-11.3)] and age/sex/surgery/BMI-matched obese controls (N = 155).Weight loss and obesity-related comorbidities up to 5 years after bariatric surgery were compared and changes in hormonal replacement therapy evaluated.Mean weight loss at 5-year follow-up was 22.0% (95% CI 16.1, 27.8) in patients versus 29.5% (28.0, 30.9) in controls (P = 0.02), which was less after Roux-en-Y gastric bypass (22.7% [16.9, 28.5] vs. 32.0% [30.4, 33.6]; P = 0.003) but at a similar level after sleeve gastrectomy (21.7% [-1.8, 45.2] vs. 21.8% [18.2, 25.5]; P = 0.96). No major changes in endocrine replacement therapy were observed after surgery. One patient died (unknown cause). One patient had long-term absorptive problems.Obese patients with craniopharyngioma had a substantial mean weight loss of 22% at 5-year follow-up after bariatric surgery, independent of type of bariatric surgery procedure. Weight loss was lower than in obese controls after Roux-en-Y gastric bypass. Bariatric surgery appears effective and relatively safe in the treatment of obese craniopharyngioma patients.

- Patients with craniopharyngioma are at an increased risk for cardio- and cerebrovascular mortality. The metabolic syndrome (MetS) is an important cardiometabolic risk factor, but barely studied in patients with craniopharyngioma. We aimed to investigate the prevalence of and risk factors for the MetS and its components in patients with craniopharyngioma.Cross-sectional study with retrospective data.We studied the prevalence of and risk factors for the MetS and its components in 110 Dutch (median age 47 years, range 18-92) and 68 Swedish (median age 50 years, range 20-81) patients with craniopharyngioma with ≥3 years of follow-up (90 females (51%); 83 patients with childhood-onset craniopharyngioma (47%); median follow-up after craniopharyngioma diagnosis 16 years (range 3-62)). In Dutch patients aged 30-70 years and Swedish patients aged 45-69 years, we examined the prevalence of the MetS and its components relative to the general population.Sixty-nine (46%) of 149 patients with complete data demonstrated the MetS. Prevalence of the MetS was significantly higher in patients with craniopharyngioma compared with the general population (40% vs 26% (P < 0.05) for Dutch patients; 52% vs 15% (P < 0.05) for Swedish patients). Multivariable logistic regression analysis identified visual impairment as a borderline significant predictor of the MetS (OR 2.54, 95% CI 0.95-6.81; P = 0.06) after adjustment for glucocorticoid replacement therapy and follow-up duration. Age, female sex, tumor location, radiological hypothalamic damage, 90Yttrium brachytherapy, glucocorticoid replacement therapy and follow-up duration significantly predicted components of the MetS.Patients with craniopharyngioma are at an increased risk for the MetS, especially patients with visual impairment.

Tidskriftsartikel (refereegranskat)abstract
- Excess of growth hormone (GH) and insulin-like growth factor 1 (IGF-1), as in acromegaly, is associated with an increased risk of diabetes, but whether retinal vessels are altered is unknown. The aim of this study was to evaluate retinal vessel morphology in patients with acromegaly at diagnosis and after treatment and to describe the prevalence of diabetic retinopathy in patients with long-standing acromegaly and diabetes.Two independent observational studies, one being prospective and the other retrospective and cross-sectional.Retinal vessel morphology of 26 patients with acromegaly was examined at diagnosis and 1 year after treatment and compared to 13 healthy controls. Cross-sectional evaluation of 39 patients with long-standing acromegaly and diabetes was performed. Fundus photographs were digitally analyzed for vessel morphology.Patients with acromegaly had a median (interquartile range) of 34.3 (30.0-39.0) vessel branching points compared to 27.0 (24.0-29.0) for healthy controls (P < 0.001). Tortuosity of arterioles and venules remained unchanged. Vessel morphology did not change significantly after treatment. Patients with acromegaly and diabetes for a median of 14 years also had a high number of branching points [34.2 (32.5-35.6)], but the prevalence of diabetic retinopathy was not higher than expected in diabetic patients without acromegaly.Patients with acromegaly have an increased number of vascular branching points in the retina without an alteration of macroscopic vessel morphology. This is consistent with an angiogenic effect of GH/IGF-1 in humans. The prevalence of diabetic retinopathy was not increased in patients with acromegaly and diabetes.
