Craniopharyngioma (CP) is a rare epithelial low-grade tumour that develops in the sellar/suprasellar region of the brain, along the craniopharyngeal duct. It has a bimodal distribution and the first peak occurs in paediatric age almost exclusively consisting of the adamantinomatous subtype. A second peak occurs in adulthood after the fifth decade of life and is more likely to be of the papillary subtype. Therapy is based on surgical removal, so the best approach is the endonasal approach, which is sometimes associated with radiation therapy. Molecular target drugs are a promising novelty, indeed they are already in use in adults and are being tested in children. Although CP is considered a low malignancy tumour, its localization and close relationships with important structures such as the optical pathways, the hypothalamic-pituitary axis and the thalamus burden it with important complications (visual disturbances, central obesity, dysendocrinopathies) that can interfere with the patient’s quality of life.

Hypothalamic Pituitary Axis

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. An 11-year-old male with a history of metastatic tectal plate low-grade glioma who was diagnosed at age 2.8 years transferred his care to the long-term follow-up clinic. He completed treatment with multiagent chemotherapy—carboplatin, vincristine, temozolomide, procarbazine, lomustine, and thioguanine—at age 4.5 years and did not require radiotherapy. At primary diagnosis, he presented with hydrocephalus that required ventriculoperitoneal shunt placement, with a subsequent shunt revision at age 6 years. Residual metastatic tumors in the third and fourth ventricles and in the suprasellar region remained stable for more than 5 years. The patient achieved normal developmental milestones and was not taking medications. He was offered screening for hypothalamic-pituitary axis (HPA) dysfunction because of his suprasellar lesion. His height was at the 25th percentile for chronological age, with decline from the 50th percentile noted during the preceding 18 months ( Fig 1 , point c). Pubertal stage was Tanner 4 for pubic hair and penile size, which contrasted with small testes (4.5 mL). Pubic hair and voice changes were noticed 2 to 3 years before this visit. Plasma testosterone level was consistent with Tanner 4 (255 ng/dL = 8.9 nmol/L). An x-ray of the left hand revealed a notably advanced bone age of 15.5 years. Plasma free T4, thyroid-stimulating hormone (TSH), and 8 am cortisol levels were normal. The patient was referred to the endocrinology clinic where he was diagnosed with growth hormone deficiency and was started on replacement therapy. He reached his final adult height of 144.1 cm at age 13.3 years ( Fig 1 , point d).

Object. Although still controversial, many authors currently advocate extensive resection in the treatment of low-grade gliomas (LGGs). Because these tumors usually migrate along white matter pathways, the corpus callosum is often invaded. Nevertheless, there is evidently no specific study featuring resection of the corpus callosum infiltrated by glioma, despite abundant literature concerning callosotomy in epilepsy surgery or transcallosal ventricular approaches. The aim of this paper was to analyze functional outcome following removal of corpus callosum invaded by LGG and to analyze the impact of this callosectomy on the quality of resection. Methods. Between 1996 and 2002, a total of 32 patients harboring an LGG involving part of the corpus callosum and having no or only a mild preoperative deficit underwent surgery aided by intraoperative electrical mapping to preserve eloquent structures identified on stimulation and to perform the most extensive resection possible. Preoperatively, no clinical response was elicited on stimulation of the corpus callosum; thus, the part of this structure that was invaded by LGG was removed. Despite immediate postoperative neurological worsening, all patients but one recovered within 3 months and returned to a normal socioprofessional life. The additional callosectomy allowed for nine total resections, 18 subtotal resections, and five partial resections. Furthermore, only two cases of contralateral hemispherical migration occurred during a median follow up of 3 years. Conclusions. Resection of the corpus callosum infiltrated by glioma improves the quality of tumor removal without increasing the risk of sequelae.

Abstract BACKGROUND Cannabinoids, including cannabidiol (CBD) and tetrahydrocannabinol (THC), are a class of compounds found in marijuana. Numerous studies in adults have examined cannabinoid use in management of cancer-related symptoms such as nausea, anorexia, and pain. Less is known about the use in the pediatric oncology population. METHODS A prospective observational study has been ongoing since 2016 at Children’s Hospital Colorado to evaluate cannabinoids’ impact using PedsQL™ modules on quality of life of pediatric patients with central nervous system (CNS) tumors who are 2–18 years old. Laboratory assessments of T-cell activity and pharmacokinetics of CBD, THC and associated metabolites are in process. Diaries with exploratory information on cannabinoid use patterns are being collected. RESULTS Thirty-three patients (14:19; male:female) have been enrolled with a median age of 6.4 years (range, 2.9–17.7 years). The most common tumor type in enrolled patients is embryonal tumors (13/33; 39%). Nine (27%) patients have low-grade glial/glioneuronal tumors, and eight (24%) had high-grade/diffuse midline gliomas. The remaining patients had ependymoma or craniopharyngioma. The median time on cannabinoids is 9 months. Most (n=20) patients have used oral products with CBD and THC. One patient continues on cannabinoid therapy in follow up. Preliminary immune function analyses identified impaired neutrophil superoxide anion production and chemotaxis in patients taking cannabinoids at early time points on therapy. CONCLUSIONS Families of children with various CNS tumors are pursuing cannabinoid therapy for both antitumor and supportive care purposes. Analysis of the impact of cannabinoids on patients’ quality of life is ongoing.

Abstract INTRODUCTION Low grade glioma (LGG) is the most common central nervous system (CNS) tumor in children accounted for 30–50%. Regarding benign characteristic of disease, surgical management remains the mainstay of treatment. However, surgical approach is limited in some conditions such as location at brainstem or infiltrative tumor. Chemotherapy and radiation treatments have been included in order to control tumor progression. The 5-years survival rate is approach 90% especially in patients who receive complete resection. However, the outcome of children with LGG in low to middle income is limited. Therefore, the aim of the study was to determine long-term outcome of children with newly diagnosed LGG. METHODS A retrospective study enrolled children aged <18 years who were newly diagnosed LGG during January 2006- December 2019. Diagnosis of LGG was confirmed by histological findings of grade I and II according to WHO criteria. RESULTS A total of 40 patients, female to male ratio was 1:1.35 and mean (SD) for age was 6.7 (4.0) years. The most common location was optic chiasmatic pathway (42.5%), followed by suprasellar region (25.0%). Sixty percent of patients received at least partial tumor removal. Chemotherapy and radiation had been used in 70% and 10.0% respectively. The 10-year progression free survival was 74.1±11.4% and overall survival was 96.2±3.8%. SUMMARY: Treatment of Pediatric LGG mainly required surgical management, however, chemotherapy and radiation had been used in progressive disease. The outcome was excellent.

Polydimethylsiloxane (PDMS) has been widely used as a vitreous humour substitution in vitreoretinal surgery. Due to its limited availability and increasing domestic needs, the price of PDMS in Indonesia became very expensive. Previously, we reported the synthesized of PDMS from a high grade of monomer of 98% of Octamethylcyclotetrasiloxane (D4) and found that all PDMS samples produced high quality samples similar to that of commercial one. However, by considering the ease of obtaining raw materials and also the production costs, the synthesis of PDMS using monomer which easy to be found in Indonesia and low production costs is needed to be developed. Here, we reported the synthesis of PDMS using low grade of 96% of D4 in order to produce high quality of PDMS with low viscosity that can be used for vitreous humous substitution in vitreoretinal surgery. PDMS samples with low viscosity value of 0.94-1.35 Pa.s have been successfully synthesized from low grade of D4 and MM using ring-opening polymerization method. The yields of PDMS resulted in this research were in the range between 67.27% and 76.26%. From FTIR spectroscopy, it is found that all synthesized samples have structure and functional groups similar to PDMS using high grade of monomer of 98% Octamethylcyclotetrasiloxane (D4). From refractometer and surfgauge measurements, all samples have refractive index in the range of 1,4034-1,4040 and the value surface tension was 21 m.N/m.
