Effects of 5-ALA dose on resection of glioblastoma

Journal of Neuro-Oncology, 2019
Fluorescence-guided surgery (FGS) with the use of 5-aminolevulinic acid (5-ALA) leads to more extensive resection of high-grade glioma (HGG) and longer overall survival (OS) of patients compared to conventional resection. The purpose of this study is to investigate the effect of 5-ALA dosages on residual tumor volume (RTV) and OS in patients with ...

5-ALA fluorescence in intraparenchymal endodermal cysts

Acta Neurochirurgica, 2017
In recent years, new indications have been suggested for 5-ALA, particularly for cystic lesions. We report the use of 5-ALA fluorescence in an intraparenchymal supratentorial endodermal cyst of a 52-year-old female presenting with headache, progressive right side hemiparesis and anomic aphasia.

Impact of 5-ALA in meningioma resection grading

2021
Objective: Recurrence after meningioma surgery may occur even after complete tumor resection (Simpson grade I). One possible cause may be the presence of remnant tumor cells that were left behind and not identified using microscope`s white light. Almost all meningiomas are aminolevulinic acid (5-ALA)[for full text, please go to the a.m. URL]

Established and emerging uses of 5-ALA in the brain: an overview

Journal of Neuro-Oncology, 2019
5-aminolevulinic acid (5-ALA) was approved by the FDA in June 2017 as an intra-operative optical imaging agent for patients with gliomas (suspected World Health Organization Grades III or IV on preoperative imaging) as an adjunct for the visualization of malignant tissue during surgery. 5-ALA fluorescence-guided surgery (FGS) has been in widespread use

Combination of 5-ALA and iMRI in re-resection of recurrent glioblastoma

British Journal of Neurosurgery, 2016
Objective: Tumor resection plays a role in the initial treatment but also in the setting of recurrent glioblastoma (rGBM). In order to achieve maximum resection, 5-aminolaevulinic acid (5’ALA) and intraoperative MRI (iMRI) can be used as surgical tools. 5’ALA is a very helpful fluorescent[for full text, please go to the a.m. URL]
