Methods： From Oct. 1999 to Dec. 2001, 22 patients with primary liver cancer underwent postoperative after-loading radiotherapy 3-10 days after hepatectomy and chemotherapy using gemcitabine （1400 mg every week for 3 weeks, repeated after one week interval, total cycles were 6） and compared with 22 cases of sole hepatectomy. Three-six catheters were placed for irradiation after hepatectomy. The single-dose of after-loading radiotherapy was 10 Gy, 24 sessions per person. Results＇. The rate of AFP negative-reversion was 100% （17/17） in the treated group, higher than in control group （62.5%, 10/16, P〈0.05）. In the treated group, the 1-year relapse rate, metastasis rate and survival rate were 18.2% （4/22）, 0 and 100% （22/22） respectively, while in the control group they were 45.5% （10/22）, 13.6% （3/22） and 77.3% （17/22） respectively. There were significant differences between the two groups in relapse rate, metastasis rate and survival rate within a year （P〈0.05）. Conclusion： Postoperative after-loading radiotherapy with gemcitabine is an effective way for the treatment of primary liver cancer.展开更多
