Background: Only sporadic reports of fluorescence-guided surgery (FGS) have been published for non-glioma conditions. In this study, we focus on epidemiological data of fluorescence patterns and report the diverse experiences of FGS in non-gliomas.
Methods: During 8.5 years between July 2010 and January 2019, 900 FGS for brain tumor performed in Seoul National University Hospital. Among them, a total of 73 histologically proven non-glioma patients were analyzed. Indications for FGS have been the possibility of anaplastic tumor in intra-axial tumors in preoperative MRI and an attempt to reproduce known anecdotal experiences of 5-Aminolevulinic Acid (5-ALA) fluorescence.
Results: In cases of brain tumors except for gliomas, the most frequent cases were brain metastasis (23 cases) followed by lymphomas (9 cases) and meningeal tumors (8 cases). And there were embryonal tumors (6 cases), hemangioblastomas (4 cases), and solitary fibrous tumor/hemangiopericytomas (3 cases). Most brain metastases, meningiomas, primary central nervous system lymphomas, and treatment effect cases showed positive fluorescence. Moreover, some non-tumorous conditions also showed positive fluorescence. However, hemangioblastoma and germ cell tumor did not observe any fluorescence at all.
Conclusion: 5-ALA induced fluorescence is not limited to glioma but is also evident in non-glioma and non-neoplastic conditions. This 5-ALA-induced fluorescence may be used as an intraoperative tool for various brain conditions.
