The detection of monoclonal expansions of the immunoglobulin heavy chain (IgH) or the T-cell receptor-gamma (TCRgamma) chain genes is an important supplement for the diagnosis of the non-Hodgkin's lymphomas (NHLs). Detection of monoclonality by polymerase chain reaction (PCR) method has offered an efficient approach for rapid diagnosis and monitoring of the therapeutic effects. Here we conducted a retrospective PCR clonality study on 49 cases of NHLs including 23 B-cell lymphomas (BCLs), 20 peripheral T-cell lymphomas (PTCLs), 6 natural killer (NK)/T-cell lymphomas and 3 reactive lymphoid tissues from southern Taiwan. Genomic DNAs from paraffin sections were extracted and analyzed by the IgH- and TCR-specific PCR reactions. The results showed that 20 of 23 (87.5%) BCLs exhibited IgH gene rearrangements and were all germline for TCRgamma. 15 of 20 (75.0%) PTCLs exhibited TCRgamma gene rearrangements while 1 case (5%) was positive for IgH gene rearrangement. The 6 NK/T-cell lymphomas and 3 reactive lymphoid tissues were all germline for either IgH or TCRgamma genes. Our results were similar to other Western reports in terms of sensitivity and cell-lineage specificity. This is the first large series of PCR clonality study of IgH a...Continue Reading

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.

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.
