Table 1.

Surviving fraction was calculated as the ratio of colony number in treated wells to the colony number in untreated wells at different initial cell densities, for three studied human cancer cell lines, namely, human gastric carcinoma, human prostate carcinoma, and human breast adenocarcinoma cell lines

Cells	Percentage of SF various initial cell densities
	10	50	100	200
AGS	19.23	53.8	50	51.9
PC3	33.56	40.2	41.9	42.5
MCF7	62.11	59.6	82	81
