Absence of well-defined borders of the glial tumor due to their infiltrative growth is one of the main issues in neurosurgery. A number of methods for intraoperative visualization are available today. The fluorescent metabolic navigation with 5-aminolevulinic acid (5-ALA) combined with quantitative laser spectroscopy is one of the latest technique. In our series of 99 consecutive patients with brain gliomas (WHO Grade I-IV) we found that visible fluorescence was observed in 68% of cases. Additional use of the laser spectroscopy could increase method sensitivity up to 74% due to accumulation of the protoporphyrine IX in nonfluorescense tumors. It was shown that there are some differences in quantitative fluorescence not only within same tumor (glioblastoma) but also in-between low- and high-grade gliomas. Intraoperative fluorescence and laser spectroscopy are effective and very helpful methods of intraoperative imaging in of intrinsic brain tumor surgery. |
