| Abstract: | We describe additional nonrandom chromosome abnormalities in 18 cases of intermediate- to high-grade non-Hodgkin's lymphoma (NHL) bearing (t(14;18) that were ascertained in a prospective cytogenetic study of all lymphomas seen at Memorial Hospital during the period January 1, 1984, to December 31, 1986. These included seven cases that had histological evidence of transformation from a lower grade and 11 that lacked such evidence. The most common of the additional changes seen in both groups affected chromosomes 6 and 7 and comprised the loss of chromosome 6 or del(6q) and the presence of more than two copies of chromosome 7 or duplication of 7q. Changes affecting these two chromosomes were less frequent in low-grade lymphomas with t(14;18) as well as in lymphomas lacking the translocation. These data suggest that common cytogenetic mechanisms underlie expression of high-grade histologies by lymphomas carrying (t14;18). In addition, they may serve as indicators of transformation when encountered in low-grade lymphomas with t(14;18). |
