摘要: Karyotype evolution of t(14;18)-positive lymphoma was studied in 13 Japanese patients. The extra 18q- chromosome, found six ten patients with complex karyotypes, the most common change subsequent to a t(14;18)(q32;q21) chromosome translocation. additional interpreted as being duplication an derived from t(14;18). had transformed histology follicular small cleaved cell or diffuse large lymphoma, and five them extranodal expansion associated poor prognosis. These findings indicate that 18q-, together other abnormalities, is closely advanced grade disease evolutionally comparable second Philadelphia (Ph1) often blastic phase chronic myelocytic leukemia carrying t(9;22)(q34;q11). In addition, since rarely American there appears be difference karyotype between
