Abstract

A pilot study on relationships of selected molecular factors (c-myc oncogene average gene copy numbers (AGCN); serum CEA and CA 15.3 antigen levels; tumor cells' DNA values), to the ex vivo chemosensitivity of primary female human breast cancer in a modified adenosine triphosphate cell viability chemosensitivity assay (ATP-CVA), was performed. Four drug combinations were tested. A group of 75 cases of female primary breast cancer was assessed. Numerous correlations were found among molecular factors tested but none, with the exception of tumor grading, of these reflected ex vivo chemosensitivity of tumors tested. The results suggest that the parameters tested may not be important factors related to adjuvant chemoresponsiveness of primary human breast cancer to tested drug combinations.
