BACKGROUND There is an unmet need for new biomarkers able to predict both the outcomes of up–front therapy and the compliance of elderly patients diagnosed with glioblastoma. For this purpose, temporal muscle thickness is a promising tool to be investigated. METHODS Data from 52 glioblastoma patients older than 65 years, treated with post-operative radio or radio-chemotherapy and referred to Pisa University Hospital, were retrieved. The thickness of temporal muscle (TMT) was divided into quartiles and correlated with overall survival (Our primary endpoint). Survival curves were calculated using Kaplan–Meier method, and log-rank test was used to evaluate the differences between curves. RESULTS Patients in the lower quartile of TMT, with TMT thinner than 7 mm, have survived longer; both univariate and multivariate analyses showed a statistically significant correlation between TMT and overall survival (P = 0.012 and P = 0.003, respectively). CONCLUSION Future prospective and more extensive studies focused on elderly glioblastoma patients are needed to confirm the role of TMT as prognostic value on OS and to help explaining this association.

Abstract

BACKGROUND There is an unmet need for new biomarkers able to predict both the outcomes of up–front therapy and the compliance of elderly patients diagnosed with glioblastoma. For this purpose, temporal muscle thickness is a promising tool to be investigated. METHODS Data from 52 glioblastoma patients older than 65 years, treated with post-operative radio or radio-chemotherapy and referred to Pisa University Hospital, were retrieved. The thickness of temporal muscle (TMT) was divided into quartiles and correlated with overall survival (Our primary endpoint). Survival curves were calculated using Kaplan–Meier method, and log-rank test was used to evaluate the differences between curves. RESULTS Patients in the lower quartile of TMT, with TMT thinner than 7 mm, have survived longer; both univariate and multivariate analyses showed a statistically significant correlation between TMT and overall survival (P = 0.012 and P = 0.003, respectively). CONCLUSION Future prospective and more extensive studies focused on elderly glioblastoma patients are needed to confirm the role of TMT as prognostic value on OS and to help explaining this association.
