Mutations in the protocadherin-19(PCDH19)gene(Xq22.1)cause the X-linked syndrome known as developmental and epileptic encephalopathy 9(DEE9,OMIM#300088)(Dibbens et al.,2008).DEE9 is characterized by early-onset clustering epilepsy associated with intellectual disability ranging from mild to profound,autism spectrum disorder,and other neuropsychiatric features including schizophrenia,anxiety,attentiondeficit/hyperactivity,and obsessive or aggressive *** seizures may become less frequent in adolescence,psychiatric comorbidities persist and often worsen with age(Dibbens et al.,2008;Kolc et al.,2020).

Aim:It remains unclear what the best therapeutic option for recurrent glioma patients after Stupp treatment ***(BVZ)is commonly administered in progression,but it appears that only some patients *** would be useful to find biomarkers that determine beforehand who these patients ***:The protocol included 31 high-risk progressing glioma patients after Stupp treatment who received BVZ 5-10 mg/kg every 14 days and temozolomide(3-19 cycles,150-200 mg five days each 28-day cycle)during a mean of eight cycles of BVZ or until tumor progression or unacceptable *** analyzed the clinical outcome values of inflammatory indices measured before BVZ ***:Lymphocyte level before BVZ administration was the best independent predictor of overall survival(HR=0.34;95%CI:0.145-0.81;P=0.015).The area under the receiver operating characteristic(ROC)curve was 0.823,with 1.645 being the optimal cut-off value,and 0.80 and 0.85 the sensitivity and specificity values,*** and non-responder survival curves were also significantly different,considering the first and second tertiles as cut-off *** number of BVZ cycles was not related to *** neutrophil platelet levels,platelet-to-lymphocyte ratio(PLR),and neutrophil-to-lymphocyte ratio(NLR)did not have independent predictive *** variables were not correlated with each ***,patients with high NLR and PLR simultaneously(double positive PLR-NLR)showed a worse clinical outcome than the rest(P=0.043).Conclusion:Pretreatment lymphocyte levels and double positive PLR-NLR could be used as non-invasive hematological prognostic markers for recurrent gliomas treated with bevacizumab.A close relationship emerged between inflammation and angiogenesis.
