Chromosome aberrations were evaluated in the lymphocytes of 30 patients who had undergone radiotherapy several years before for non-Hodgkin's lymphoma. Twelve had received 20 Gy over the entire abdomen (group I), 12 wholebody irradiation at 1.5 Gy (group II) and 6 wholebody irradiation at 15 Gy (group III). Unirradiated patients seen for cytogenetic analysis during the same period served as controls. Overall results for the irradiated population were 13/27 (48%) evaluable patients with chromosome aberrations and 50/710 (7%) abnormal cells for a total of 73 aberrations (unstable: 35, stable: 38). The frequency of aberrations was statistically higher in group I (12% of cells) than in groups II (3.5%, p < 0.0001) and III (2.5%, p < 0.0002). Differences in irradiation dose and volume may account for the variations between groups.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008224 Lymphoma, Follicular Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
