Aim . To create a collection of plasma samples patients with brain tumors (BTs) for the development diagnostic microRNA (ribonucleic acid) panel glial tumors. Material and methods Plasma benign malignant BTs were obtained by double centrifugation whole blood then frozen at -75оС.Fifty-nine RNA isolated from analyzed next-generation sequencing (NGS). Results Currently, biobank contains 339 primary secondary 10 control group individuals (698 — 2 aliquots per individual), including 143 men 206 women. The age ranged 19 to 91 years (median 56 years). Primary (41%) included two following groups: (33,7%) (66,3%). Meningiomas constituted bulk (91%) BTs. Among tumors, glioblastomas (46,7%) astrocytomas (41,6%) prevailed, while oligodendrogliomas ependymomas accounted only 9,1 2,5%, respectively. Secondary (59%) are represented recurrent (92,5%) metastatic (7,5%) lung cancer (71,4%) breast (28.6%). A protocol preparation liquid biopsy was implemented, which made it possible obtain high-quality deoxyribonucleic acid libraries selected profiling platform. Conclusion creation sample is basis searching circulating biomarkers

Purpose of the study . Is to describe experience creating a collection biological images tumor tissues and biomaterials, which are control samples, for scientific research in morphology molecular oncology. Materials methods. We studied markers cell cycle regulation, apoptosis, oncogenesis angiogenesis, expression proteins that regulate inflammation infiltrate cells biocollections verified tumors common localizations: e. g. thyroid cancer, colorectal breast prostate adenocarcinoma, endometrioid adenocarcinoma. Also, tissue fragments with normal structure or non-tumor pathology (autoimmune thyroiditis, adenomatous thyrotoxic goiter, benign formations colon, fibrocystic disease mammary glands, prostatic hyperplasia, endometrial hyperplasia) were used as samples comparison groups. The total number is n = 7000. Results. It reasonable gather pathomorphological laboratory according profile medical institutions, has sufficient volume incoming target material specialized morphologists verify given localization. necessary consider regional ethnic specifics population, determines sampling mutational load. must initiate an addition informed consent patients about possibility conducting morphological genetic studies purposes publishing their results depersonalized form development new elaborations, when signing contracts legal entities individuals serving within institution. When working biocollections, it having registers biomaterials disorder groups main localizations downloading by year from accessible information system, external factors affecting database (changes clinical recommendations classifications, population served, pandemics other significant events). standard preanalytical stage, data collection, protocols analytical evaluation, utilization capabilities reagents tasks modeling experiments on animals crucial. Conclusion. formed biocollection made possible carry out initiative funded domestic international projects at request clinicians fundamental researchers, well improve quality standards oncology diagnostics. Biobanking makes pathological archive more review use, significantly expanding its practical potential. Scientific do not conflict can be same laboratory.
