Abstract:
Objective To evaluate the effects of three-dimensional conformal radiation therapy (3DCRT) on the local control and survival of patients with local recurrence or metastasis in colorectal cancer. Methods Twenty-three patients with local recurrence or metastasis in colorectal cancer were irradiated by 3DCRT. The regimen was: total dose 40-45?Gy, 5-7?Gy/f, 1f/2d. Results Of the 23 patients, 8 achieved CR and 9 PR with a total response rate of 74%(17/23). The overall 1-, 2-and 3-year survival rates were 78%,52% and 30%. Conclusion 3DCRT is able to prolong the survival and improve the life quality of patients with local recurrence or metastasis in colorectal cancer.
