Background High-grade gliomas (HGGs) are aggressive brain tumors with poor prognoses. Maximizing the extent of resection (EOR) is a critical surgical goal. Fluorescence-guided surgery using 5-aminolevulinic acid (5-ALA) has been proposed to enhance tumor visualization and resection. MethodsWe retrospectively analyzed 141 patients with histologically confirmed HGGs who underwent either 5-ALA-guided ( = 71) or conventional white-light ( = 70) resection between 2018 and 2023. Propensity score matching and multivariate Cox regression models were used to assess the impact of 5-ALA on surgical outcomes and survival. Results: Gross total resection (GTR) was significantly more common in the 5-ALA group than the conventional white-light group (28.17% vs. 12.86%, = 0.0245). Kaplan-Meier analysis showed no statistically significant difference in overall survival between groups after matching (log-rank = 0.6371). However, patients with GTR had significantly improved survival compared to those with subtotal resection (log-rank = 0.0423). Multivariate Cox regression identified radiotherapy (HR = 0.291, 95% CI: 0.166-0.513, < 0.001), higher Karnofsky Performance Status (HR = 0.962, 95% CI: 0.942-0.982, = 0.0003), and GTR (HR = 0.476, 95% CI: 0.272-0.834, = 0.0091) as independent predictors of improved survival. 5-ALA usage was not an independent predictor (HR = 0.885, 95% CI: 0.554-1.413, = 0.612). Radiotherapy and chemotherapy were more frequently administered in the conventional white-light group ( = 0.0404 and = 0.0085, respectively). Conclusions 5-ALA fluorescence-guided surgery significantly increases the rate of gross total resection in high-grade glioma patients but does not independently confer a survival advantage. Survival outcomes are primarily influenced by the extent of resection, adjuvant therapy, and functional status. Integration of 5-ALA within a comprehensive oncological framework may enhance its clinical utility.
高级别胶质瘤（HGGs）是预后较差的侵袭性脑肿瘤。最大化切除范围（EOR）是关键的手术目标。已提出使用5-氨基乙酰丙酸（5-ALA）进行荧光引导手术以增强肿瘤可视化和切除效果。
我们回顾性分析了2018年至2023年间141例经组织学确诊为HGGs且接受了5-ALA引导切除（n = 71）或传统白光切除（n = 70）的患者。采用倾向评分匹配和多变量Cox回归模型来评估5-ALA对手术结果和生存的影响。
5-ALA组的全切除（GTR）明显比传统白光组更常见（28.17%对12.86%，P = 0.0245）。Kaplan-Meier分析显示匹配后两组间总生存无统计学显著差异（对数秩检验P = 0.6371）。然而，与次全切除患者相比，GTR患者的生存有显著改善（对数秩检验P = 0.0423）。多变量Cox回归确定放疗（HR = 0.291，95%CI：0.166 - 0.513，P < 0.001）、较高的卡诺夫斯基功能状态（HR = 0.962，95%CI：0.942 - 0.982，P = 0.0003）和GTR（HR = 0.476，95%CI：0.272 - 0.834，P = 0.0091）是生存改善的独立预测因素。5-ALA的使用不是独立预测因素（HR = 0.885，95%CI：0.554 - 1.413，P = 0.612）。传统白光组放疗和化疗的应用更频繁（分别为P = 0.0404和P = 0.0085）。
5-ALA荧光引导手术显著提高了高级别胶质瘤患者的全切除率，但并未独立带来生存优势。生存结果主要受切除范围、辅助治疗和功能状态的影响。将5-ALA整合到综合肿瘤学框架内可能会提高其临床效用。
