High-dose methotrexate (MTX; ≥1 g/m2 ) is a renally eliminated and nephrotoxic first-line therapy for central nervous system (CNS) lymphoma. Creatinine-based estimation of renal function is the recommended approach to dosing MTX in these cases, but nonrenal determinants of creatinine production and elimination in cancer patients such as malnutrition and cachexia lead to overestimation of glomerular filtration rate (GFR) by this method and a heightened risk for drug toxicity. Serum cystatin C is one of the first readily available, relatively inexpensive, endogenous biomarkers to emerge as a practical adjunct to creatinine for estimation of renal function for drug dosing...

PURPOSE: Although advanced MRI techniques are increasingly available, imaging differentiation between glioblastoma and primary central nervous system lymphoma (PCNSL) is sometimes confusing. We aimed to evaluate the performance of image classification by support vector machine, a method of traditional machine learning, using texture features computed from contrast-enhanced T1 -weighted images. METHODS: This retrospective study on preoperative brain tumor MRI included 76 consecutives, initially treated patients with glioblastoma (n = 55) or PCNSL (n = 21) from one institution, consisting of independent training group (n = 60: 44 glioblastomas and 16 PCNSLs) and test group (n = 16: 11 glioblastomas and 5 PCNSLs) sequentially separated by time periods...

While thyroid cancer risks from exposure to ionizing radiation early in life are well characterized quantitatively, the association of radiation with nonmalignant, functional thyroid disorders has been less studied. Here, we report on a risk analysis study of hypothyroidism with radiation dose to the thyroid gland and the hypothalamic-pituitary axis among survivors of childhood cancer. Utilizing data from the Childhood Cancer Survivor Study, a cohort of 14,364 five-year survivors of childhood cancer diagnosed at 26 hospitals in the U...

Background: To describe the recent diagnostic and treatment options for the most predominant form of primary vitreoretinal lymphoma (PVRL), namely diffuse large B cell lymphoma. This is mainly based on the experience at the Mayo Clinic as well as a partial review of the literature. MYD88 L265P mutation is seen in about 80% of cases; therefore, a polymerase chain reaction for this mutation helps in making the diagnosis that has been notoriously difficult to make. Local therapy using intravitreal methotrexate and rituximab has been very helpful in the treatment of the local disease...

PURPOSE: Alectinib is a selective and potent anaplastic lymphoma kinase (ALK) inhibitor that is active in the central nervous system (CNS). Alectinib demonstrated robust efficacy in a pooled analysis of two single-arm, open-label phase II studies (NP28673, NCT01801111; NP28761, NCT01871805) in crizotinib-resistant ALK-positive non-small-cell lung cancer (NSCLC): median overall survival (OS) 29.1 months (95% confidence interval [CI]: 21.3-39.0) for alectinib 600 mg twice daily (BID). We investigated exposure-response relationships from final pooled phase II OS and safety data to assess alectinib dose selection...

BACKGROUND: Many studies have examined long-term outcomes after childhood cancer, but few address outcomes for adolescent and young adult (AYA; those aged 15-39 years) cancer survivors. Conditional survival reflects changing mortality risk with time since cancer diagnosis and is a useful measure for planning long-term follow-up care. METHODS: Using the Surveillance, Epidemiology, and End Results registry 9 database, the authors identified a cohort of AYA patients diagnosed with a first malignant cancer between 1973 and 2009 and followed through 2014...

Treatment of Burkitt lymphoma (BL) with intensive, multi-agent chemotherapy with aggressive central nervous system (CNS) prophylaxis results in high cure rates, although no regimen is standard of care. We examined population-based survival outcomes of adults with BL treated with a modified combination of cyclophosphamide, vincristine, doxorubicin, prednisone and systemic high-dose methotrexate (MTX) (CODOX-M) with IVAC (ifosfamide, mesna, etoposide, cytarabine and intrathecal MTX) (CODOX-M/IVAC) ± rituximab over a 15-year period in British Columbia...

Primary central nervous lymphoma (PCNSL) is a rare extra-nodal subtype of non-Hodgkin lymphoma and most cases are of diffuse large B-cell lymphoma histology with an aggressive presentation. The treatment of PCNSL has evolved over the years from radiation alone to multi-agent chemotherapy with the goal of minimizing long-term toxicity. Recent studies have evaluated autologous stem cell transplant as consolidation in eligible patients with success. The prognosis of relapsed disease remains poor and hence the emphasis is on effective and less toxic frontline strategies...

BACKGROUND: The physical function of children with cancer is reduced during treatment, which can compromise the quality of life and increase the risk of chronic medical conditions. The study, "REhabilitation, including Social and Physical activity and Education in Children and Teenagers with cancer" (Clinicaltrials.gov: NCT01772862) examines the efficacy of multimodal rehabilitation strategies introduced at cancer diagnosis. This article addresses the feasibility of and obstacles to testing physical function in children with cancer...

PTEN loss has been associated with poorer prognosis in many solid tumors. However, such investigation in lymphomas is limited. In this study, PTEN cytoplasmic and nuclear expression, PTEN gene deletion, and PTEN mutations were evaluated in two independent cohorts of diffuse large B-cell lymphoma (DLBCL). Cytoplasmic PTEN expression was found in approximately 67% of total 747 DLBCL cases, more frequently in the activated B-cell-like subtype. Nuclear PTEN expression was less frequent and at lower levels, which significantly correlated with higher PTEN mRNA expression...

Gliomas are the most common malignant brain tumors and account for around 60% of all primary central nervous system cancers. Glioblastoma multiforme (GBM) is a grade IV glioma associated with a poor outcome despite recent advances in chemotherapy. The etiology of gliomas is unknown, but neurotropic viruses including the Epstein-Barr virus (EBV) that is transmitted via salivary and genital fluids have been implicated recently. EBV is a member of the gamma herpes simplex family of DNA viruses that is known to cause infectious mononucleosis (glandular fever) and is strongly linked with the oncogenesis of several cancers, including B-cell lymphomas, nasopharyngeal, and gastric carcinomas...

Secondary nervous system lymphoma (SCNSL) is a rare extranodal form of non-Hodgkin lymphoma (NHL). This applies to a particular form of lymphoma that does not originally derive from the central nervous system (CNS); it can be both an isolated form of relapse or a systemic part of disease progression. Due to poor prognosis and a lack of established algorithms of therapeutic procedures, it is a big challenge for physicians from many specializations. In our study, we present an interesting case of a patient with a relapsed form of SCNSL for whom a unique form of treatment was used - intraventricular administration of rituximab and methotrexate...

Treatment strategies and outcomes were assessed in 25 patients with primary breast diffuse large B-cell lymphoma (PB-DLBCL) treated between 1995 and 2016. We specifically investigated the timing of recurrence, and the roles of radiotherapy (RT) and central nervous system prophylaxis (CNS PPX). Fifty-two percent of patients received RT, and 28% received CNS PPX. Fourteen patients (56%) experienced recurrence, with 76% of relapses occurring ≥24 months after diagnosis, in contrast to reports supporting the use of 24-month event-free survival as a surrogate endpoint in the general DLBCL population...

Neuroprotective strategies using diazoxide (DZX) have been demonstrated to limit ischemia/reperfusion (I/R)‑induced injury and cell apoptosis. In type 2 diabetes mellitus, DZX has been reported to improve β‑cell function and reduce their apoptosis, through suppressing endoplasmic reticulum (ER) stress. However, the effects of DZX on ER stress during I/R‑induced neuronal apoptosis in the hippocampus remains to be elucidated. In the present study, pretreatment of hippocampal neurons with DZX was revealed to inhibit oxygen‑glucose deprivation (OGD)‑stimulated apoptosis in vitro and to alleviate I/R‑induced hippocampal injury and behavioral deficits in rats in vivo...
