Abstract

To determine whether the MR-detectable white matter changes associated with high-dose chemotherapy and bone marrow transplant in patients with advanced breast carcinoma are accompanied by neurochemical disturbances detectable by proton MR spectroscopy. MR studies were obtained in 13 patients, and single-voxel proton MR spectra were acquired in vivo in 12 of these 13 for comparison with 13 age- and sex-matched control subjects. Considerable white matter change determined with MR was found in 10 of 13 patients with volume white matter change ranging from 1 to 153 cm3 (mean, 49 cm3; SD, 50 cm3). Single-voxel spectra successfully acquired in 12 patients revealed no significant difference in patients compared with control subjects for the spectral ratios N-acetyl aspartate to creatine or N-acetyl aspartate to choline at either short or long echo times (30 and 136 milliseconds). Extensive, late-stage white matter change induced by high-dose chemotherapy is not accompanied by measurable disturbances in the putative neuronal marker N-acetyl aspartate, suggesting that chemotherapy-induced white matter disease is predominantly a water space and possibly an extraneuronal process rather than a primary neuronal (axonal) disease. The MR spec...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
