对20例中晚期肝癌病人进行液氮冷冻治疗。肿瘤直径7～20cm,平均13cm。肝细胞性肝癌16例,肝母细胞瘤1例,胆管细胞癌3例,全组病人进行了随访,死亡5例,平均存活10个月。余15例1、2、3年生存率各占60％、35％和10％。能够独立生活的11例中,5例可参加轻体力劳动。结果说明液氮冷冻治疗可作为中晚期肝癌的一种姑息疗法,可以缓解症状,延长寿命。
20 patients with advanced liver cancer were treated with liquid nitrogen cryotherapy. Tumor diameter 7 ~ 20cm, an average of 13cm. There were 16 cases of hepatocellular carcinoma, 1 case of hepatoblastoma, and 3 cases of cholangiocellular carcinoma. All the patients were followed up and 5 cases died. The average survival time was 10 months. In the remaining 15 cases, the 1-, 2-, and 3-year survival rates each accounted for 60%, 35%, and 10%. Of the 11 cases that were able to live independently, 5 were able to participate in light physical work. The results suggest that liquid nitrogen cryotherapy can be used as a palliative treatment for advanced liver cancer, which can relieve symptoms and prolong lifespan.
