Proton therapy for treatment of intracranial benign tumors in adults: A systematic review.

Cancer Treat Rev 2018 Dec 1;72:56-64. Epub 2018 Dec 1.

Radiation Oncology Department, Centre François Baclesse, Caen, France; Archade, Advanced Resource Center for Hadrontherapy in Europe, Caen, France; Normandy University, Université de Caen Basse Normandie, Caen, France; Laboratoire de Physique Corpusculaire, Caen, France.

Introduction: The depth-dose distribution of a proton beam, materialized by the Bragg peak makes it an attractive radiation modality as it reduces exposure of healthy tissues to radiations, compared with photon therapy Prominent indications, based on a long-standing experience are: intraocular melanomas, low-grade skull-base and spinal canal malignancies. However, many others potential indications are under investigations such as the benign morbid conditions that are compatible with an extended life-expectancy: low grade meningiomas, paragangliomas, pituitary adenomas, neurinomas craniopharyngioma or recurrent pleomorphic adenomas.

Materials: Given the radiation-induced risk of secondary cancer and the potential neurocognitive and functional alteration with photonic radiotherapy, we systematically analyzed the existing clinical literature about the use of proton therapy as an irradiation modality for cervical or intracranial benign tumors.

Lack of Sphenoid Pneumatization Does Not Affect Endoscopic Endonasal Pediatric Skull Base Surgery Outcomes.

Laryngoscope 2018 Dec 5. Epub 2018 Dec 5.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Pennsylvania, Philadelphia, Pennsylvania.

Objectives/hypothesis: Currently, due to the rarity of pathology, there are limited data surrounding outcomes of pediatric skull base surgery. Traditionally, surgeons have proceeded with caution when electing endonasal endoscopic transsellar/transplanum approaches to the skull base in pediatric patients due to poor sphenoid pneumatization. In this study, we review outcomes of endoscopic pediatric skull base surgery based on sphenoid pneumatization patterns. Read More

Oxytocin therapy in hypopituitarism: challenges and opportunities.

Clin Endocrinol (Oxf) 2018 Dec 2. Epub 2018 Dec 2.

Schools of Medicine (RB, DAR) and Psychology (KLD), Neuroscience and Mental Health Research Institute, Cardiff University, Cardiff, CF24 4HQ, UK.

Patients with hypopituitarism display impaired quality of life and excess morbidity and mortality, despite apparently optimal pituitary hormone replacement. Oxytocin is a neuropeptide synthesised in the anterior hypothalamus which plays an important role in controlling social and emotional behaviour, body weight and metabolism. Recent studies have suggested that a deficiency of oxytocin may be evident in patients with hypopituitarism and craniopharyngioma, and that this may be associated with deficits in cognitive empathy.

Harvey Cushing's craniopharyngioma treatment: Part 1. Identification and clinicopathological characterization of this challenging pituitary tumor.

Authors:

J Neurosurg 2018 Oct 1:1-15. Epub 2018 Oct 1.

OBJECTIVEHarvey Cushing (1869-1939) coined the term "craniopharyngioma" (CP) in 1929 to describe a kaleidoscopic group of epithelial tumors involving the hypothalamic-pituitary axis. Throughout his career, he endured a long struggle to accurately diagnose and safely remove these complex lesions, and his resulting surgical series has never before been analyzed in depth. The authors here conduct such an analysis. Read More

Preserve or sacrifice the stalk? Endocrinological outcomes, extent of resection, and recurrence rates following endoscopic endonasal resection of craniopharyngiomas.

Authors:

J Neurosurg 2018 Nov 1:1-9. Epub 2018 Nov 1.

OBJECTIVEGross-total resection (GTR) of craniopharyngiomas (CPs) is potentially curative and is often the goal of surgery, but endocrinopathy generally results if the stalk is sacrificed. In some cases, GTR can be attempted while still preserving the stalk; however, stalk manipulation or devascularization may cause endocrinopathy and this strategy risks leaving behind small tumor remnants that can recur.METHODSA retrospective review of a prospective cohort of patients who underwent initial resection of CP using the endoscopic endonasal approach over a period of 12 years at Weill Cornell Medical College, NewYork-Presbyterian Hospital, was performed.

Authors:

J Neurosurg 2018 Nov 1:1-11. Epub 2018 Nov 1.

OBJECTIVEIntrinsic third ventricular craniopharyngiomas (IVCs) have been reported by some authors to "pose the greatest surgical challenge" of all craniopharyngiomas (CPAs). A variety of open microsurgical approaches have historically been used for resection of these tumors. Despite increased utilization of the endoscopic endonasal approach (EEA) for resection of CPAs in recent years, many authors continue to recommend against use of the EEA for resection of IVCs.

A modern series of subdiaphragmatic craniopharyngiomas.

Authors:

J Neurosurg 2018 Oct 1:1-6. Epub 2018 Oct 1.

OBJECTIVEThe endoscopic endonasal approach has been proposed as a primary surgical strategy for select craniopharyngiomas. However, those tumors that arise from the sella have not been classified with the other craniopharyngioma subtypes in terms of surgical nuances, intraoperative findings, and postoperative outcomes. The authors describe their experience with a select subtype of craniopharyngioma arising within the sella subjacent to the diaphragma sellae and refer to these tumors as type 0. Read More

Advances in the management of craniopharyngioma.

F1000Res 2018 11;7. Epub 2018 Oct 11.

Department of Radiation Oncology, University of Florida, 2015 North Jefferson Street, Jacksonville, FL 32206, USA.

Craniopharyngioma is a curable benign tumor, but owing to its intimate relationship to critical structures in the central brain-such as the optic apparatus, pituitary, hypothalamus, intracranial vasculature, brain stem, and temporal lobes-its management introduces the risk of long-term treatment morbidity. Today, the most common treatment approach is conservative subtotal resection followed by radiotherapy, and the goal is to limit long-term toxicity. Many recent advances in the treatment of craniopharyngioma are attributable to improved surgical techniques and radiotherapy technologies. Read More

Background: Near-infrared (NIR) tumor contrast is achieved through the "second-window ICG" technique, which relies on passive accumulation of high doses of indocyanine green (ICG) in neoplasms via the enhanced permeability and retention effect.

Objective: To report early results and potential challenges associated with the application of second-window ICG technique in endonasal endoscopic, ventral skull-base surgery, and to determine potential predictors of NIR signal-to-background ratio (SBR) using endoscopic techniques.

Methods: Pituitary adenoma (n = 8), craniopharyngioma (n = 3), and chordoma (n = 4) patients received systemic infusions of ICG (5 mg/kg) approximately 24 h before surgery. Read More

Cognitive and Adaptive Outcomes After Proton Radiation for Pediatric Patients With Brain Tumors.

Int J Radiat Oncol Biol Phys 2018 10 6;102(2):391-398. Epub 2018 Jun 6.

Harvard Medical School, Harvard University, Boston, Massachusetts; Department of Radiation Oncology, Massachusetts General Hospital, Boston, Massachusetts.

Purpose: Radiation therapy is integral in treatment of pediatric brain tumors, but it is associated with negative long-term sequelae. Proton beam radiation therapy (PRT), which enables better focusing of radiation on tumors, may entail fewer sequelae. This prospective study examined cognitive and adaptive functioning in children and young adults treated with PRT. Read More

Tension pneumocephalus from skull base surgery: A case report and review of the literature.

Surg Neurol Int 2018 4;9:128. Epub 2018 Jul 4.

Faculty of Medicine, University of Sydney, Camperdown, New South Wales, Australia.

Background: Tension pneumocephalus from skull base surgery is a rare occurrence that mandates urgent neurosurgical attention.

Case Description: We describe a case of tension pneumocephalus secondary to an endoscopic endonasal resection of an adamantinomatous craniopharyngioma and how it was successfully managed at our institution.

Conclusion: Our experience reflects that definitive treatment of tension pneumocephalus is required with multilayered dural repair, but temporising measures should be used immediately to prevent neurological deterioration prior to the definitive repair. Read More
