Multicenter StudyRepeat stereotactic radiosurgery for Cushing's disease: outcomes of an international, multicenter study.
Stereotactic radiosurgery (SRS) is frequently used for Cushing's disease (CD) after failed pituitary surgery. Management of patients with persistent CD after failed SRS is complex, as the alternative therapeutic options harbor significant risks. The outcomes of repeat pituitary radiosurgery, however, have not been described. ⋯ Two patients (10%) experienced adverse radiation effects, including transient visual loss and permanent diplopia. Repeat SRS achieves lasting biochemical remission in approximately half of patients with CD refractory to both prior microsurgery and SRS. Because of the morbidity of refractory or recurrent CD, repeat SRS should be considered for carefully selected patients with hypercortisolism confirmed one or more years after initial SRS.

Multicenter Study Comparative StudyHormone receptors status: a strong determinant of the kinetics of brain metastases occurrence compared with HER2 status in breast cancer.
Breast cancer (BC) metastatic behavior varies according to the hormone receptors (HR) and HER2 statuses. Indeed, patients with triple-negative (TN) and HER2+ tumors are at higher risk of brain metastases (BM). The objective of this multinational cohort was to evaluate BM kinetics depending on the BC subtype. ⋯ HER2- tumors, p = 0.880). HR- and HER2+ tumors are overrepresented in BC patients with BM, supporting a higher risk of BM in these biological subtypes. HR status, but not HER2 status, impacts the kinetics of BM occurrence.

Incidence and survival of gliomatosis cerebri: a population-based cancer registration study.
Gliomatosis cerebri (GC) comprises a rare widespread infiltrating growth pattern of diffuse gliomas. We explored the incidence patterns and survival rates of GC in a population-based registration sample from the Surveillance, Epidemiology and End, Results database (1973-2012). GC cases (n = 176) were identified based on their International Classification of Diseases in Oncology (ICD-O-3) morphology code (9381). ⋯ Increasing age, primary tumor location not restricted to the cerebral hemispheres and rural residence at diagnosis were identified as negative prognostic factors, whereas receipt of radiotherapy, surgical treatment, race and method of diagnosis were not associated with outcome. This first comprehensive overview of GC epidemiology exemplifies the rarity of the disease, provides evidence for male preponderance and increased incidence among the elderly and shows lower survival rates compared to the published single center reports. Expansion of registration to histological and molecular characteristics would allow emergence of clinical prognostic factors at the population level.

Surgical treatment of glioblastoma in the elderly: the impact of complications.
The diagnosis of glioblastoma (GBM) often carries a dismal prognosis, with a median survival of 14.6 months. A particular challenge is the diagnosis of GBM in the elderly population (age > 75 years), who have significant comorbidities, present with worse functional status, and are at higher risk with surgical treatments. We sought to evaluate the impact of current GBM treatment, specifically in the elderly population. ⋯ The benefit of glioblastoma treatment in our series was limited by the postoperative complications and KPS. Presence of a complication served as an independent risk factor for worsened overall survival in this age group. It is likely that decreased patient function limits postoperative adjuvant therapy and predisposes to higher morbidity especially in this age group.

Multicenter StudyEnd-of-life care of children with diffuse intrinsic pontine glioma.
The end-of-life management of children with diffuse intrinsic pontine glioma (DIPG) is challenging. Families cope with debilitating symptoms and make complex decisions regarding their child's care. However, there is little evidence guiding palliative care provision for these children. ⋯ Children with DIPG have complex needs and require intensive multidisciplinary support. This paper describes the end-of-life choices made for these children and discusses how these choices influence our institutional model for palliative care. We believe this approach will be useful to clinicians caring for similar patients.
