应用荧光素钠显微切除儿童髓母细胞瘤

The application of fuorescein sodium for the microscopic resection of medulloblastoma

目的探讨应用荧光素钠引导显微手术治疗儿童髓母细胞瘤患者的安全性及有效性,并分析手术疗效及预后。方法回顾分析2018年1月至2023年8月新疆维吾尔自治区人民医院接受手术和病理检查的20例应用荧光素钠辅助显微手术切除髓母细胞瘤患儿的临床资料,其中12例经单侧膜帆入路,2例经双侧膜帆入路,6例采用膜帆入路联合小脑蚓部部分切开入路。术中荧光素钠的剂量为2 mg/kg。结果20例患者中,男12例,女8例,发病年龄(7.9±3.7)岁。所有病例有明确的肿瘤荧光,未出现与使用荧光素钠有关的不良反应。肿瘤全切除16例,近全切除3例,部分切除1例,术后出现颅内感染1例,皮下积液2例,小脑缄默症2例。随访3~72个月,5例未进行足量、全程放、化疗,9例因为肿瘤进展或复发死亡。所有病例中,总体生存时间最长为72个月,中位生存时间为41.2个月。结论荧光素钠辅助在儿童髓母细胞瘤手术中是安全和有效的。

Objective To investigate the safety and efficacy of sodium fluorescein-guided microsurgery in children with medulloblastoma,and to analyze the surgical efficacy and prognosis.Among them,12 cases underwent unilateral telovelar approach,2 cases underwent bilateral telovelar approach,and 6 cases underwent telovelar approach combined with transvermian approach.The intraoperative dose of sodium fluorescein was 2 mg/kg.Methods The clinical data of 20 patients with medulloblastoma treated with fluorescein sodium assisted microsurgery from January 2018 to August 2023 in Xinjiang Autonomous Region People's Hospital were retrospectively analyzed.Results Of the 20 patients,12 were male and 8 were female.The mean age of onset was(7.9±3.7)years.In all cases,there was clear tumor fluorescence,none of the cases had adverse reaction associated with the use of sodium fluorescein.There were 16 cases of gross-total resection,3 cases of near-total resection,1 case of partial resection,1 case of intracranial infection,2 case of subcutaneous effusion,2 cases of cerebellar mutism.The follow-up time was from 3 to 72 months.5 cases did not receive sufficient radiotherapy and chemotherapy,and 9 cases died due to tumor progression or recurrence.In all cases,the longest overall survival was 72 months,the mean survival time was 39.2 months,and the median survival time was 41.2 months.Conclusion Fluorescein sodium assisted microsurgery is safe and effective in pediatric medulloblastoma surgery.
