title: Philadelphia-chromosome-negative chronic myelogenous leukemia with incomplete trisomy 1q following chemotherapy for ovarian carcinoma.
abstract: A 59-year-old woman was treated with surgery followed by monthly injections of the alkylating agent thiotepa for a granulosa cell tumor of the left ovary. Chemotherapy was continued for 22 years. At the age of 84, chronic myelogenous leukemia (CML) developed. Cytogenetic studies revealed incomplete trisomy of the long arm of chromosome No. 1 as the only karyotypic abnormality. No Philadelphia chromosome was detected. The significance of trisomy 1q as an isolated cytogenetic abnormality in CML and the occurrence of CML following treatment of ovarian cancer are discussed.
