Abstract

We assessed the outcome of high-dose methotrexate (HD-MTX) chemotherapy with or without radiotherapy (RT) in primary central nervous system lymphoma (PCNSL) patients. Fifty-one HIV-negative patients with an average age of 50.3 years were treated with chemotherapy regimen included 2500 mg/m(2) MTX with Leucovorin rescue and 1.4 mg/m(2) vincristine (day two), which was administered every other week for 6 weeks. Only the patients who were younger than 60 years received RT. All patients received two cycles of 3000 mg/m(2) cytarabine at the end of the treatment for two successive days. Diffuse large B-cell lymphoma was the most common histologic subtype (90.2%), and twenty-six (51.0%)patients had multiple brain lesions. The median survival of patients who were younger than 60 years was 37 months. For patients who were older than 60 years, the median survival was 20 months. The median survival of men and women were 30 and 34 months, respectively. There was no significant difference in survival of patients in terms of age and sex. Overall, sixteen patients (31%) out of fifty-one patients died, five of them were older than 60 years and eleven were younger than 60 years. Twenty-five (49%) of all patients experienced relapse, and 10 (40%...Continue Reading

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.

CNS Lymphoma

In CNS lymphoma, cancerous cells from lymph tissues or other parts of the body form tumors in the brain and/or spinal cord. Here is the latest research on this rare non-Hodgkin lymphoma.
