Аннотация: Abstract INTRODUCTION Due to the infiltrative nature of glioblastoma(GBM) outside of the contrast enhancing region in the peritumoral zone, there is increasing movement to perform supratotal resections (SpTR) by extending the edge of resection beyond the contrast enhancing portion of the tumor. However, there is currently no consensus on the potential survival benefit of SpTR in GBM as compared to gross total resection (GTR). METHODS Therefore, we performed a systematic review using PRISMA guidelines and performed a comprehensive literature search on Pubmed, EMBASE, The Cochrane Library, Web of Science, Scopus, and ClinicalTrials.gov, from inception to August 16, 2018, to identify articles comparing overall survival (OS) after SpTR versus GTR. Furthermore, we assessed study quality using the Oxford Centre for Evidence-Based Medicine guidelines. RESULTS We identified 8902 unique citations, of which 11 articles and 2 abstracts met study inclusion criteria. 925 patients underwent SpTR out of a total of 2137 patients. 9 of the 13 studies demonstrated improved survival with SpTR compared to GTR (median improvement in OS of 10.5 months), with no significant difference in post-operative complication rate. Conversely, one abstract found worsened outcomes with SpTR compared to GTR (median decrease in OS of 4 months). However, overall study quality was poor, with 12 of the 13 studies of level IV evidence and one study of level IIIb evidence. We were unable to perform a meta-analysis due to significant clinical and methodological heterogeneity amongst the studies (e.g. differences in adjuvant therapy and lack of standardization of definition of supratotal resection). CONCLUSIONS Our systematic review indicates that SpTR may be associated with improved OS compared to GTR for GBM. However, this is limited by poor study quality and significant clinical and methodological heterogeneity amongst the studies. There is need for prospective clinical trials to further establish standardized guidelines for SpTR in GBM.
