Abstract

Surgical removal of tumor mass is a common approach in the management of brain tumors. However, the precise delineation of normal tissue from tumor tissue for a complete resection of tumor mass in brain tumor surgery remains a difficult task for neurosurgeons. Aminolevulinic acid (ALA)-mediated exgogenous fluorescence of protoporphyrin IX (PpIX) is a sensitive approach for tumor imaging. Recent studies suggest that the use of ALA/PpIX-mediated fluorescence-guided resection (FGR) or fluorescence-guided surgery can enable more accurate and complete resection of brain tumors, especially when used in quantitative fashion. This review will highlight the current progress in PpIX-mediated FGR and discuss technical challenges in intraoperative quantification of intracellular PpIX fluorescence during FGR of brain tumor.

摘要

手术切除肿瘤块是脑肿瘤治疗中的常见方法。然而,在脑肿瘤手术中,精确区分正常组织和肿瘤组织以实现肿瘤块的完全切除,对神经外科医生来说仍然是一项艰巨的任务。氨基乙酰丙酸(ALA)介导的原卟啉IX(PpIX)外源性荧光是一种敏感的肿瘤成像方法。最近的研究表明,使用ALA/PpIX介导的荧光引导切除术(FGR)或荧光引导手术能够更准确、更完整地切除脑肿瘤,尤其是以定量方式使用时。本综述将重点介绍PpIX介导的FGR的当前进展,并讨论脑肿瘤FGR过程中细胞内PpIX荧光术中定量的技术挑战。
