Abstract:
The results of cytogenetic investigations on one benign and 15 malignant breast tumors are described. Trisomy 7, 8, 18, and 21 and monosomy X occurred as clonal numerical aberrations, and inv(7)(q21q31) and t(4;12)(q21;p13) occurred as clonal structural aberrations. Only trisomy 8 was a recurrent karyotypic abnormality, however. Thus, we assumed that trisomy 8 as an early genetic change characterizes a subtype of ductal breast carcinomas.
