125I放射性粒子组织间植入治疗面神经受侵的腮腺恶性肿瘤初步临床观察

目的 观察手术及在组织间植入放射性粒子125I治疗腮腺恶性肿瘤并保存面神经的临床效果.方法 32例腮腺恶性肿瘤患者手术切除肿瘤,解剖并保留受肿瘤侵犯的面神经.根据患者具体情况制定治疗计划、125I组织间植入靶区设计,术中或术后植入放射性粒子125I.定期随诊,观察肿瘤复发情况、面神经功能恢复及放射性损伤.结果 32例患者随访12～44个月,未及肿瘤复发;未见明显放射性损伤症状.术后6个月患者面神经功能基本恢复正常.结论 通过术中或术后植入125I放射性粒子治疗面神经受侵的腮腺恶性肿瘤,可以保留受肿瘤侵犯的面神经功能,近期疗效满意.

Preliminary study of treating parotid gland malignant tumor with saving facial nerve (surgery associated with 125I seed implant brachytherapy)

OBJECTIVE: To study the clinical effect of treating parotid gland malignant tumor with facial never-preserving surgery combined with 125I seed implant brachytherapy. METHODS: Thirty-two patients with parotid gland malignancy underwent tumor and parotid gland excision while preserving facial never. According to treating plan system (TPS), 125I seeds were implanted into the target area during or after operation. The patients were followed up after operation and the local tumor control and facial nerve function were observed. RESULTS: Tumor recurrence was not found in any patient treated after 12 to 44 months of follow up. All patients did not show obvious radiation-related complications. The facial never function of all patients was basically normal 6 months after operation. CONCLUSIONS: For parotid gland malignant tumor, surgery combined with 125I seeds implant brachytherapy can save facial never function, and the short-term effects were satisfactory.
