Follow-up 3–36 months to assess patient survival.Results: Among the 62 patients, 3 months after Iodine-125 radioactive seed implantation, 5 cases(8.1%) had complete remission of cancer, 33 cases(53.2%) had partial remission, 12 cases(19.4%) had stable lesions, and 12 cases(19.4%) had disease progression. The effective rate was 61.3%. The tumor volume(31.44 ± 14.51 cm3) was significantly smaller than before(50.96 ± 30.13 cm3)(t=5.303, p < 0.05). The tumor marker AFP(69.28 ±50.99) ug/L of 3 months after implantation was significantly lower than that before treatment(90.63 ± 68.58)ug/L(t=3.702, P < 0.05). The average survival time of Iodine-125 seed implantation for stageⅣhepatocellular carcinoma is 11.47 ± 0.85 months, and the median survival time is 9 months. The survival time of the group with better pathological differentiation(grade Ⅰ+ⅡⅠ) was significantly better than that of the group with poor differentiation(grade Ⅲ+Ⅳ)(x2=6.869 p < 0.05). Among the 38 patients with different degrees of abdominal pain,22 patients improved better than before;15 of 28 patients with different degrees of ascites were better than before. All patients had no serious complications related to treatment.Conclusions: Iodine-125 radioactive seed implantation therapy can safely and effectively treat hepatocellular carcinoma, and relieve the clinical symptoms of abdominal pain and ascites.展开更多
