Cytogenetic studies are reported on 17 T-cell malignant lymphomas (ML) including six cutaneous T-cell malignant lymphomas (CTCL). Due to the low incidence of rearrangements on bands where the T-cell receptor genes are located, other cases reported in the literature were analyzed in order to estimate the most frequent chromosomal breakpoints in ML, CTCL, and adult T-cell leukemia-lymphoma. Besides chromosomes 1 and 6q, 14q11, 7p15p21, and 7q32q35, the most frequent rearrangements involved bands 14q32, 2p11-p14, 2p23-p25, 17cen, 9p21p23, and 10p13p15. These results show that molecular studies must be concentrated on these chromosomal regions in order to identify the DNA sequences that may be involved in T-cell malignancies.
本文报道了17例T细胞恶性淋巴瘤(ML)的细胞遗传学研究,其中包括6例皮肤T细胞恶性淋巴瘤(CTCL)。由于T细胞受体基因所在区域的重排发生率较低,因此分析了文献中报道的其他病例,以估计ML、CTCL和成人T细胞白血病淋巴瘤中最常见的染色体断点。除了1号染色体和6q、14q11、7p15 - p21以及7q32 - q35外,最常见的重排涉及14q32、2p11 - p14、2p23 - p25、17cen、9p21 - p23和10p13 - p15区域。这些结果表明,分子研究必须集中在这些染色体区域,以识别可能与T细胞恶性肿瘤相关的DNA序列。
