摘要
目的 评价超声引导经皮微波固化疗法在肝癌的应用。方法 采用改良的超声引导经皮微波固化疗法 (percutaneousmicrowavecoagulationtherapy ,PMCT)治疗肝癌 12例 ,包括肝细胞性肝癌 7例 ,转移性肝癌 5例 ,共 16个结节 ,直径 1 5～ 6 4cm ,平均 3 8cm ,其中直径大于 3cm的结节 6个。结果 经首次治疗 ,随访 3～ 10个月 (平均 8 1个月 ) ,14个结节完全坏死 ,局部复发结节 2个。另外肝内远处多发转移 2例 ,单发转移 1例。局部复发及远处单发转移者经再次PMCT亦获得治愈。PMCT前后肝脏功能无明显改变。结论 通过适当延长微波辐射时间和采用多针多点组合辐射的方法 ,PMCT不仅治疗小肝癌疗效确切 ,亦能有效杀灭直径 3cm以上的癌灶。
Objective [WT5”BZ]To evaluate the effect of ultrasound guided percutaneous microwave coagulation therapy (PMCT) for liver cancer. [WT5”HZ]Methods [WT5”BZ] PMCT was undertaken in 12 patients with liver cancer including 7 cases of hepatocellular carcinoma and 5 cases of metastatic carcinoma. Sixteen cancer foci in 12 cases ranging from 1.5cm to 6 4cm in diameter (mean, 3 8cm) were treated, among which 6 nodules were larger than 3 0cm.[WT5”HZ] Results [WT5”BZ] During the follow up period of 3 to 11 months (mean, 8 1 months), completed necrosis was observed in 14 nodules. Local recurrence was detected in 2 nodules and remote recurrence was found in 3 cases. All nodules became necrotic after a second session of PMCT.No deterioration of the hepatic function test was observed after the therapy.[WT5”HZ] Conclusions [WT5”BZ]By prolonging the irradiation duration and using multiple point of punctures, PMCT induced complete necrosis of cancer foci not only of less than 3cm in diameter but also larger.
