Abstract
A prospective cohort study was structured to examine patient's tumor mass factors that could determine a specific cognitive function profile in patients with Malignant Glioma who survived after the Stupp protocol, while adjusting for previously explored confounding factors. Neuropsi - Attention and Memory (Second edition) was applied after tumor resection, but before any other oncological treatment. Follow-up neuropsychological evaluation was conducted when patients completed the Stupp protocol treatment scheme. To estimate the mean difference between follow-up and baseline Neuropsi subtest scores, a Bayesian Mixed Effects Model was fitted with three random-effect regressors representing tumor locations, co-administered medications and by-patient cognitive performance variability. Sixteen patients were included. Temporal lobe tumors were the most frequent (31.2%) and more than three-fourths of those were located in the left lobe; such results agree with the clinical and statistical significance that supports an impairment in the Semantic Verbal Fluency subtest (Mean score change = -5.97, 95% Credible Interval = [-8.01, -3.80]). The findings suggest that any potential variants in a determined cognitive dysfunction profile could be more influenced by tumor location than any other variable related to the patient's tumor mass or administered oncological medications; however, because the limited sample representativeness, additional studies are required.
