开发一个基于儿科患者脑肿瘤切除术后是否需要脑室腹腔分流术（VP）分流的独立预测因素的评分系统。共有 416 名接受手术的脑肿瘤儿科患者（≤ 14 岁）被随机分配参加培训(n = 333) 和验证队列 (n = 83)。根据 VP 分流的实施情况，将训练队列分为 VP 分流组（n = 35）和非 VP 分流组（n = 298）。进行了单变量和多变量逻辑分析。根据临床特征和手术数据制定评分系统，计算评分和相应的风险。年龄<3（p = 0.010，比值比[OR] = 3.162），失血量（BL）（p = 0.005，OR = 1.300）、中线肿瘤位置（p < 0.001，OR = 5.750）、术前脑积水（p = 0.001，OR = 7.044）和全切除（p = 0.025，OR = 0.284）被确定为独立预测因素。评分系统的曲线下面积（AUC）高于年龄<3、BL、中线肿瘤位置、术前脑积水和全切除组（分别为0.859 vs. 0.598、0.717、0.725、0.705和0.555； p < 0.001）。此外，评分系统在验证队列中表现出良好的性能（AUC = 0.971）。预测评分的截止值为 5.5 分，将患者分为低风险（0-5 分）和高风险（6-14 分）组。我们的评分系统，整合年龄 < 3、BL、中线肿瘤位置、术前脑积水和全切除提供了实用的评估。分数范围从 6 到 14 分表示高风险。版权所有 © 2023 郭、钟、彭、刘和陈。

To develop a scoring system based on independent predictors of the need for ventriculoperitoneal (VP) shunt after brain tumor resection in pediatric patients.A total of 416 pediatric patients (≤ 14 years old) with brain tumors who underwent surgery were randomly assigned to the training (n = 333) and validation cohorts (n = 83). Based on the implementation of VP shunt, the training cohort was divided into the VP shunt group (n = 35) and the non-VP shunt group (n = 298). Univariate and multivariate logistic analyses were performed. A scoring system was developed based on clinical characteristics and operative data, and scores and corresponding risks were calculated.Age < 3 (p = 0.010, odds ratio [OR] = 3.162), blood loss (BL) (p = 0.005, OR = 1.300), midline tumor location (p < 0.001, OR = 5.750), preoperative hydrocephalus (p = 0.001, OR = 7.044), and total resection (p = 0.025, OR = 0.284) were identified as independent predictors. The area under the curve (AUC) of the scoring system was higher than those of age < 3, BL, midline tumor location, preoperative hydrocephalus, and total resection (0.859 vs. 0.598, 0.717, 0.725, 0.705, and 0.555, respectively; p < 0.001). Furthermore, the scoring system showed good performance in the validation cohort (AUC = 0.971). The cutoff value for predictive scores was 5.5 points, which categorized patients into low risk (0-5 points) and high risk (6-14 points) groups.Our scoring system, integrating age < 3, BL, midline tumor location, preoperative hydrocephalus, and total resection, provides a practical evaluation. Scores ranging from 6 to 14 points indicate high risk.Copyright © 2023 Guo, Zhong, Peng, Liu and Chen.
