目的 :探讨冷冻治疗肝癌的临床应用技术和效果。方法 :应用 L CS- 2 0 0 0型深度液氮冷冻治疗机 ,对原发性肝癌 6例和继发性肝癌 2例进行了冷冻治疗。结果 :全部患者均手术顺利 ,无手术死亡及严重并发症 ,多数不良反应为疼痛、发热、AL T/AST和胆红素升高。病理显示冷冻区内肝细胞和癌细胞呈凝固性坏死。2例转移性肝癌均于手术后 2年内死亡。 1例巨块型肝癌于手术后 1年死亡。 2例肝癌于手术后 3年死亡。另 3例肝癌现健在 ,已分别存活 3年、3年和 4年。结论 :冷冻治疗肿瘤成功的关键是能否将肿瘤细胞彻底地冷冻致死。冷冻治疗是肝癌治疗的一种手段 ,它有一定的适应证和局限性。如果掌握的好 ,疗效高 ,并发症少
Objective: To explore the clinical application techniques and effects of cryotherapy for liver cancer. Methods : L CS-200 deep liquid nitrogen cryotherapy machine was used to treat 6 cases of primary liver cancer and 2 cases of secondary liver cancer. RESULTS: All the patients were operated smoothly without operative death and serious complications. Most of the adverse reactions were pain, fever, AL T/AST and elevated bilirubin. Pathology showed coagulative necrosis of hepatocytes and cancer cells in the frozen area. Two cases of metastatic liver cancer died within 2 years after surgery. One case of massive liver cancer died 1 year after surgery. Two cases of liver cancer died 3 years after surgery. The other 3 cases of liver cancer are healthy and have survived for 3 years, 3 years and 4 years respectively. Conclusion : The key to the success of cryotherapy for cancer is whether it can completely freeze the tumor cells to death. Cryotherapy is a means of liver cancer treatment, and it has certain indications and limitations. If you have good control, high curative effect and less complications
