Objectives : The purpose of this study was to aid in the prediction of tumor cell
tolerance to radiotherapy and/or chemotherapy.
Material and Methods : Human epidermoid carcinoma A-431 cell lines were irradiated
by 2, 4, 6, 8, 10Gy at a dose rate of 210cGy/min using 60Co Irradiator
ALDORADO 8 and then were exposed to bleomycin or cisplatin at concentration of 21¥ì
g/§¢ for 1 hour. The viable cells were determined for each radiation dose and/or each
drug at the 4th day and cell surviving curves were obtained using semiautomated MTT
assay.
Results : The surviving fraction after irradiation of 2Gy was 0.99. and there was not
significant difference of surviving fraction in comparison with the control group on
A-431 cell line(P>0.05). But there were significant differences of surviving fractions at
doses of 4, 6, 8, 10Gy in comparison with the control group(P<0.05). The cytotoxicity of
bleomycin or cisplatin was significantly different in comparison with the control group
on A-431 cell line (P<0.05) And the cytotoxicity of cisplatin was greater than that of
bleomycin on A-431 cell line (P<0.05). There were significant differences of surviving
fractions after irradiation of 2, 4, 6, 8, 10Gy with bleomycin or cisplatin in comparison
with each group of irradiation only on A-431 cell line(P<0.05). There were significant
differences of surviving fractions between the groups o# irradiation with bleomycin and
cisplatin at doses of 2, 4Gy(P<0.05), but there were not significant differences of
surviving fractions at doses of 6, 8, 10Gy on A-431 cell line (P>0.05).
