Abstract

Working with the antimetabolic chemopredictivity assay on short term cultures we evidenced a correlation between in vitro chemosensitivity of colorectal cancer and fractional incorporation of radionucleotides. Four difTerent drugs (5-FU. mitomycin C, 4¢-iododeoxydoxorubicin and ruboxyl, a nitroxyl derivative of daunorubicin) were tested on 102 tumor cultures. The extent of³H-TdR and³H-UdR incorporation into DN A and RNA in the related control cultures was in relationship with the chemosensitivity of the tumor. Along with the labeling index this simple metabolic-kinetic trait may gain a role for the screening of tumor phenotypes sensitive to chemotherapy.
