经皮微波热凝治疗原发性和转移性肝癌

目的 经皮微波肝穿刺热凝损毁肝癌是个新的治疗方法,使用该法观察其对肝癌的作用疗效和安全性。方法 100例患者在局麻或硬膜外麻醉下,接受了经皮微波肝穿刺热凝损毁肝癌治疗,其中原发性和复发性肝癌79例,转移性肝癌21例。肿瘤总数186个,被分成瘤体直径<3cm的A组和瘤体直径≥3 cm-<5cm的B组。在局部麻醉或硬膜外麻醉下,单针或双针阵列的微波天线在B超的引导下直接经皮肝穿刺插入瘤体中对其行热凝损毁。结果 100例患者的186个瘤体中,直径<3cm A组的肿块123个(66％)能1次手术热凝损毁,其中112个(91％)经CT或MRI检查,并随访6-12个月,提示瘤体热损毁后未见复发;直径≥3 cm-<5cm B组的肿块63个(33.87％),被分2次手术,术后6个月 CT或MRI检查提示,31个热凝损毁(49％),32个大部分热凝损毁(51％)。经皮微波热凝治疗(PMCT)的患者均未见明显的不良反应和其他严重并发症。结论 PMCT治疗肝癌,尤其对直径<3cm的瘤体疗效可靠,对直径≥3cm-<5cm的瘤体仍具有大部分或完全热损毁的作用。它是一种微创、有效、安全的治疗方法,对肝功能较差的患者也可使用。

Percutaneous microwave coagulation therapy for patients with primary and metastatic hepatic tumors

Objective: To evaluate the efficacy and safety of percutaneous microwave coagulation therapy (PMCT) for patients with primary and metastatic hepatic tumors.Methods: The enrolled 100 patients with 186 tumor nodules who underwent PMCT included 79 cases of primary or recurrent liver cancers and 21 cases of metastatic liver cancer. The tumors were divided into two groups according to the tumor size in diameter: group A, 0.5 cm−<3 cm; group B, ≥3 cm−<5 cm. Under local and/or epidural anesthesia, a single percutaneous microwave antenna (or two antennas array applicator) was inserted directly into the tumor in the liver for thermo-coagulation with the aid of ultrasound guidance.Results: Among the 186 lesions in 100 patients with primary and metastatic liver cancers, in group A, 123 (66%) were coagulated once. A Follow-up of 6–12 months demonstrated that 112 lesions (91%) showed no local recurrence by CT or MRI; In group B, of the 63 lesions (33.87%) coagulated twice, 31 (49%) showed no local recurrence by CT or MRI during a follow-up of 6 months. There were no serious clinical side effects or complications in all the PMCT patients.Conclusion: PMCT gives satisfactory curative effect on tumors with <3 cm in size. It is partly effective on lesions ≥3 cm−<5 cm in size. It is a minimally invasive and effective therapy, can be used safely in the field of percutaneous hepatis surgery, and carried out even in patients with poor liver function.
