Tumor using the efficient concomitant radiotherapy and chemotherapy to remove, prior to surgery and, either reduce the size of the tumor after surgery, or was can be made smaller, Or excised tumor, in a way to be removed, most conventional surgical method is surgical excision surgery therapy. And methods reduce or tumor size, or smaller, chemotherapy can kill tumor is administered selectively anticancer agent which increases the radioactive susceptible to tumor cells, sensitive to susceptibility to radiation are those which make it possible to respond to, either TRAIL methods of various biological cytostatic can deform the protein, by deforming the structure of the protein help to cell death it is known. In this paper, the HCT-116 cells thought to be a cancer cell to analyze the interaction of TRAIL and radiation. Experimental results, single use of TRAIL and radiation, results were compared with the control group, it was found to have no significant effect on each cell proliferation and apoptosis. Conversely treated with TRAIL, when treated in parallel radiation, it was possible to know that the HCT-116 cells significantly apoptosis occurs, The proportion of G1 ratio G0 also was found to have increased. TRAIL conclusion is increased apoptosis radiation defensive cells can know that increased radiosensitivity, also possible to alter the cell cycle, reduce cell proliferation ability stepwise it was possible. TRAIL is increased apoptosis, decreased cell proliferative capacity, it is considered to be possible to use as a radiation sensitizer.
