Background: 5-Aminolevulinic acid (5-ALA) is a prodrug used to selectively illuminate high-grade glioma (HGG) tissue intra-operatively, shown to nearly double complete resection rates in a 2006 multicentre, phase III clinical trial. Here, we review the history of the 2020 approval of 5-ALA in Canada and present some of the first preliminary results on resection rates, survival analysis, and adverse effects from a single Canadian center. Methods: We enrolled 76 patients (median age 61 years, 42 male) with suspected HGG amenable to surgical resection between June 2020 and January 2023. Gross total resection was defined by the absence of enhancing lesions on postoperative MRI. We compared the survival distributions of confirmed HGG cases with complete vs. incomplete resection using a log-rank test and Kaplan-Meier statistic. Results: 52 patients were confirmed as having a HGG based on a pathological diagnosis. In 32 of these patients (60.3%) a gross total resection was achieved. 82.76% were still alive at 180 and 270 days, and 72.73% at 360 days. 47.8% had a survival of 600 or more days. Conclusions: 5-ALA fluorescence-guided surgery resulted in high complete resection rates, and improved overall survival comparable to the literature with no notable adverse side effects.
