Abstract:
The aim of this study was to investigate the effect of fractioned radiation on the sensitivity of NCI-H446 small cell lung cancer cell line to chemotherapeutic drug and its mechanism. Exponentially growing NCI-H446 cells were exposed to 50 Gy radiation which was administered in 25 fractions with 2 Gy per fraction. The survival rate of NCI-H446 cell line was observed after the interference of different concentration of Mitomycin C given before and after fractioned radiation treatment. The survival rate of the radiated cells was higher than that of the unradiated cells with the same concentration of Mitomycin C(P
