Cytogenetic studies were conducted on fresh and cultured cells from 11 patients with human T-cell leukemia virus-associated adult T cell leukemia-lymphoma. Clones with abnormal karyotypes were detected in 9 of the 11 patients. Chromosome numbers were near-diploid in cells from all but 1 patient who also had a tetraploid clone. The chromosome abnormalities in these cells were extensive; numerous complex structural changes were seen in every chromosome pair. Structural abnormalities occurred frequently in chromosome 6. The 6 patients with chromosome 6 deletions had breakpoints at bands q11, q13, q16q23, q21q23, q22q24, and q23q24. The characteristic clinical features of these 6 patients were aggressive course, short survival, poor response to chemotherapy, high white blood cell counts, hypercalcemia, and bone lesions, whereas cytogenetically abnormal patients without chromosome 6q deletions tended to have a more indolent course. The precise role of the 6q deletion cannot be established with certainty from these data. However, this abnormality appears to occur with a greater than expected frequency in this large cell aggressive lymphoma, in association with hypercalcemia and lytic bone lesions.
