Adult T-cell leukemia/lymphoma (ATLL) is a rare and highly aggressive type of peripheral T-cell lymphoma associated with human T-lymphotropic virus, type I (HTLV-I) infection. ATLL has a long latency and only a small percentage of HTLV-I infected individuals develop ATLL, suggesting the requirement of additional genetic events for neoplastic transformation of HTLV-I infected lymphocytes. The disease is endemic in several regions of the world, in particular, southwestern Japan and the Caribbean basin. The clinical features of Caribbean ATLL have been reported to differ from Japanese cases, includ- ing a younger age at diagnosis, higher frequency of the lymphomatous subtype, and a more aggressive clinical course [1–7]. A number of publications have described the cytogenetic profile of Japanese ATLL [8–11]; however, cytogenetic data on Caribbean ATLL are limited [5,6]. In this study, we assessed the cytogenetic alterations in a large series of Caribbean ATLL cases to investigate whether the differences in the types and frequencies of karyotype abnormalities account for the reported differ- ences in clinical presentation and outcome between Japanese and Caribbean patients.
