BackgroundRed cell distribution width (RDW), neutrophil–lymphocyte ratio (NLR), and platelet count (PLT) routinely tested as part of the complete blood count are indicative of systemic inflammation. The prognostic significance of NLR and PLT in cancer was demonstrated in many studies while the role of RDW has been hardly investigated. The present study aimed to assess the association of RDW, NLR, and PLT with survival and tumor grade in glioma patients.MethodsClinical data from 178 patients with primary gliomas treated in a single institution were retrospectively analyzed. Receiver operating characteristic curves for cutoff value determination, Kaplan–Meier survival analysis, various bivariate tests, and univariate and multivariate Cox regression analyses were performed.ResultsPatients with high RDW (≥13.95) and NLR (≥4) levels had worse overall survival (OS) (Wilcoxon test, P<0.026 and P<0.003, respectively) while the effect of thrombocytosis (≥400×109/L) on prognosis was not significant. Besides, a strong association between RDW and NLR was found (Spearman’s rho =0.230, P<0.02; χ2=8.887, P<0.03; Mann–Whitney U-test, P<0.017). Moreover, RDW and NLR were significantly associated with tumor grade. In univariate Cox analysis, elevated NLR (hazard ratio, HR 1.385; confidence interval, CI 1.020–1.881, P<0.037), older age (HR 0.452, CI 0.329–0.621, P<0), and higher tumor grade (HR 1.624, CI 1.187–2.223, P<0.002) were associated with poor outcomes. In the multivariate analysis, tumor grade, age, and Karnofsky performance score were identified as being independently prognostic for OS.ConclusionPreoperative NLR and RDW values can help to evaluate disease progression and outcomes in patients with gliomas, thereby contributing to patient follow-up optimization.

Background: Glioma patients with mutant isocitrate dehydrogenase have improved survival; this could be in part due to the suppressive effect of mutant IDH on the level of chronic inflammation. This study aimed to prospectively analyze the association of IDH1 mutation status with preoperative levels of blood inflammatory markers: neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR), C-reactive protein (CRP), and red cell distribution width (RDW) in gliomas. Patients and methods: Receiver operating characteristic curves for cutoff value determination, various bivariate tests, and survival analyses (Kaplan–Meier curves and Cox regression) were performed. Results: Patients with mutant IDH1 had reduced levels of NLR ( P <0.032) and CRP ( P <0.008). Moreover, these patients showed better median overall survival compared to those without IDH1 mutation ( P <0.000). In univariate analysis, IDH1 mutation status ( P <0.000), NLR ( P <0.000), PLR ( P <0.008), and CRP ( P <0.001) were among the factors associated with survival. By multivariate analysis, IDH1 mutation ( P <0.044) and NLR<2.65 ( P <0.022) remained independent factors associated with better survival; other independent variables were tumor grade ( P <0.000) and location in noneloquent area ( P <0.015). Conclusion: The obtained results show that IDH1 mutation is associated with lower levels of chronic inflammation that could account for an improved prognosis in this group of patients.

Background: Studies of quality of life (QoL) of oncological patients is carried out using questionnaires approved in many international clinical studies. The European Organization for Research and Treatment of Cancer EORTC QLQ-C30 (Quality of Life Questionnary-Core 30) and its special brain cancer module EORTC QLQ-BN20 are widely used in the world neurooncologic practice. They are available in more than 80 official versions of 30 languages of the world. Previously we used the official versions in Russian, which often causes difficulty in understanding for native Kazakh language speakers, who comprise more than 60% of our respondents. This was the reason for creating a version of Kazakh language. Therefore, in 2014 for the first time the process of adaptation of questionnaires to the Kazakh language was initiated. Materials and Methods: The translation process of questionnaires to Kazakh language was held in accordance with the requirements of the European Organization for Research and Treatment of Cancer EORTC on QoL and consisted of the following stages: preparation -translation -pilot testing -approval. The official permission of authors and "Guideline on translation" was obtained which was developed by the working group of the EORTC on QoL. The pilot testing of EORTC QLQ-C30 and QLQ-BN20 questionnaires was conducted on the basis of the Department of Central Nervous System Pathology of the "National Centre for Neurosurgery" in patients with malignant tumors of the central nervous system. Results: The official versions of the EORTC QLQ-C30 and QLQ-BN20 questionnaires in Kazakh language were introduced and adapted in practical neurosurgical operations in Kazakhstan. Conclusions: The approved versions of the questionnaires in Kazakh language are now available for mainstream use on the official website EORTC.com. The versions of these questionnaires can be used in domestic cohort studies and clinical practice in the Republic of Kazakhstan. The use of these tools for assessing QoL will help professionals in the planning of individual treatment strategies and selection of the necessary therapy.

We present a case of fourth ventricle anaplastic ependymoma in a pregnancy which was the first result of three rounds of in vitro fertilization (IVF) and embryo transfer. Whether hormonal treatment can directly or indirectly precipitate brain tumors to develop or become symptomatic is unclear.
