title: Double minute chromatin bodies in carcinoma of the human cervix uteri.
abstract: In direct G-banded preparations of 150 cases of cervical cancer, double minutes (dmin) were observed in 43% (64 cancers) of the patients, including a case of carcinoma-in-situ (CIS). The incidence of dmin varied from 1 to over 20 per cell. The karyotypic findings in the tumors containing dmin did not reveal any similarities and the prognosis of the patients with dmin was significantly worse compared to those without dmin. The presence of dmin in cytogenetic preparations of primary tumors may indicate a role in the maintenance and/or progression of malignancy, particularly as dmin have been suggested to represent amplified genes.
