The amplified c-myc gene in a colon adenocarcinoma cell line, COLO 320HSR, and the amplified mdr-1 gene in an adriamycin-resistant myelogenous leukemia cell line, K562/ADM, were not eliminated by BA.
Consequently, the levels of c-myc gene expression observed in primary tumor tissue did not help to define those individuals at higher or lower risk for recurrence of disease and did not point to the likelihood of increased or decreased survival in individuals undergoing surgery for adenocarcinoma of the colon.
