结直肠癌术后局部复发或转移的三维适形放疗

目的评价三维适形放疗对术后局部复发或转移的结直肠癌患者局部控制率和生存率的影响。方法23例术后局部复发或转移的结直肠癌患者采用三维适形放疗，5—7Gy／次，隔日1次，共6—8次，总剂量0140—45Gy。结果完全缓解率为35％(8／23)，部分缓解率为39％(9／23)，有效率为74％(17／23)。1、2、3年生存率分别为78％、52％、30％。结论三维适形放疗可提高术后局部复发或转移结直肠癌的控制率和生存率，改善其生存质量。

Three-dimensional conformal radiation therapy for postoperative local recurrence or metastasis in colorectal carcinoma

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.
