Glioma surgery is an essential part of glioma management; however, fully achieving the goal of surgery has been uncommon. The goal of surgery is 'maximal safe resection' with the accepted target for maximal being complete resection of the contrast-enhancing tumor.
This ideal result was obtained in less than 30% of cases in centers of excellence until a few years ago. The development of fluorescence-guided surgery using 5-aminolevulinic acid has initiated a radical change. Over the past 5 years, various groups have published rates of complete resection of the enhancing tumor that exceed 80%. In the coming years, as the use of the technology expands, complete resection should become a common, predictable result at many centers.
Consequently, adjuvant therapies that benefit from resection could play a bigger role, resection could be incorporated as a variable in randomized trials and distant recurrence might become a more common problem.
