Normal level of spontaneous chromosome breakage in lymphocytes from patients with non-Hodgkin's lymphoma

The frequency of spontaneous structural chromosome aberrations was studied in phytohemagglutinin-stimulated lymphocytes from 25 untreated patients with non-Hodgkin's lymphoma and 25 controls. In the lymphoma group, the mean gap, break, and gap + break event frequencies (i.e., events per 100 cells) were 1.2, 2.1, and 3.4, respectively. The corresponding rates for the control group were 1.3, 1.5, and 2.8. The mean number of aberrant mitoses per 100 mitoses were 2.5 in lymphoma patients and 2.4 in controls. These differences between patients and controls were not significant (p greater than 0.05). Thus, no evidence of inherent chromosome instability or exposure to clastogenic agents in the lymphoma group was detected.

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.

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.
