颈淋巴结转移癌的氩氦靶向治疗

Percutaneous cryoablation of cervical lymph node metastases under ultrasonic guidance

目的探讨氩氦靶向(氩氦刀)治疗颈淋巴结转移癌的可行性。方法15例颈淋巴结转移癌病灶在给予局部麻醉后进行氩氦靶向冷冻治疗,经历冷冻、升温两个循环。结果14例患者的肿瘤病灶均被氩氦刀所形成的冰球完全覆盖,其余1例患者肿瘤病灶的冰球的覆盖率也在96%以上。在冷冻期间没有发生严重的并发症。结论氩氦靶向治疗能有效治疗颈淋巴结转移癌,创伤小,并发症低,是一种安全有效的肿瘤治疗方法。

OBJECTIVE To observe the feasibility and safety of cryoablation of cervical lymph node metastases for nonsurgical candidates. METHODS The procedure was performed after achievement of local anesthesia for 15 cases. In this clinical study, local anesthesia with no sedation was performed to all the patients. In all cases, patients underwent two freeze/thaw cycles. RESULTS Tumors of 14 patients were thoroughly covered by ice balls. In one patient, 96% of the tumorous lesion was covered by ice balls. In these patients, no complicated complication was observed during the treatment. CONCLUSION Percutaneous cryoablation therapy for cervical lymph node metastases under ultrasonic guidance is a feasible and minimally invasive method with satisfactory local control.
