Aim. To create a collection of samples of blood components of patients with multiple myeloma for potential fundamental and applied biomedical research.Material and methods. The material was collected according to the developed algorithm, including the collection of clinical information, biological material, sample preparation, quality control and storage in the biobank of the National Medical Research Center of Oncology.Results. As of August 2021, the cryostorage of the National Medical Research Center of Oncology biobank contains a collection of 175 samples of blood serum, plasma and mononuclear cell fraction of patients with multiple myeloma. Samples were obtained from 32 patients of both sexes, the mean age of which was 59,5±1,65 years. To create an electronic catalog, personal, clinical and laboratory data about patients were collected, after which each sample was assigned its own unique identification number. Written informed consent was obtained from all patients for the storage of their biomaterial in a biobank with possible subsequent use for scientific purposes. Freezing of the obtained samples was carried out in accordance with low-temperature storage protocol. The electronic catalog contains a wide range of systematized clinical and laboratory information on samples.Conclusion. The collection of multiple myeloma samples is a unique resource for potential research on its pathophysiology, the development of diagnostic biomarkers, and the search for targeted agents.

Ipilimumab (IPI) provides a ten-year overall survival in almost 20 % of selected patients participated in several phase II-III trials. However, the expanded access program (EAP) looks more like routine practice than like clinical trials& This is why the results of such application could be different. Here we present the long-term follow-up data of single center EAP. Ninety-six patients with disseminated melanoma progressing after at least one lines of drug therapy were included at the N.N. Petrov National Medical Research Center of Oncology. Sixty-seven (70 %) patients had stage IV M1c, 35 patients (36 %) had elevated LDH before initiating IPI therapy. All patients received IPI 3 mg / kg IV every 3 weeks for a maximum of 4 cycles. Totally, 320 cycles (mean - 3.3 per patient) were conducted. Grade 3-4 immuno-mediated adverse events (imAE) observed in 18 (19 %) patients. Three patients died of adverse events, possibly associated with ongoing therapy. The median time to progression was 3 (95 % CI, 2.4 to 3.5) mo., the median overall survival was 13 (95 % CI, 8.3 to17.6) mo. Previous immunotherapy with dendritic cell vaccines decreased the risk of death by 48 % (Log-rank p = 0.049). The wild type BRAF status increased three-year overall survival from 29 to 68 % (p = 0.042). Our data confirms long-term safety and efficacy of IPI in patients with pretreated disseminated melanoma in the close to real practice setting.

13-cis-Retinoic acid is a differentiation agent for neuroblastoma cells and is a part of post-consolidation therapy for high-risk patients. The effectiveness of this therapeutic approach is currently under study. 26 patients with high-risk neuroblastoma treated at Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology were included in the study of 13-cis-Retinoic acid pharmacokinetics by high-performance liquid chromatography assay with ultraviolet detector depending on the method of administration of drug (swallowed capsules or opened capsules before administration). This study is supported by the Independent Ethics Committee and approved by the Academic Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. The current study showed that the therapeutic concentration of > 2 μM when taking 13-cis-Retinoic acid at a dose of 160 mg/m2/day was achieved in two groups, regardless of the method of drug administration. However, plasma concentrations of 13-cis-Retinoic acid at 4 hours after administration on the 14th day of therapy were higher in the group of patients who swallowed the capsules (4.1 ± 1.8 μM), compared to those who could not do it (1.9 ± 1.5 μM) (p = 0.022). The introduction into the clinical practice of therapeutic drug monitoring of 13-cis-retinoic acid in high-risk neuroblastoma patients with an assessment of peak concentration and dose adjustment of the following courses may be an important point in the attempt to optimize postconsolidation therapy and improve prognosis.

Recent evidence suggests that a cytology–histology correlation (CHC) with discrepancy detection can both evaluate errors and improve the sensitivity and specificity of the cytologic method. We aimed to analyze the errors in cytologic–histologic discrepancies according to the CHC protocol guideline of the American Society of Cytopathology (2017). This retrospective study included 273 patients seen at the National Medical Research Center of Obstetrics, Gynecology and Perinatology (Moscow, Russia) between January 2019 and September 2021. The patients’ mean age was 34 ± 8.1 years. The cytology–histology agreement was noted in 158 cases (57.9%). Major discrepancies were found in 21 cases (7.6%), while minor discrepancies were noted in 93 cases (34.1%). The reason for 13 (4.8%) discrepancies was a colposcopy sampling error and, in 46 (16.8%) cases, the reason was a Papanicolaou (PAP) test sampling error. The discrepancy between primary and reviewed cytology was due interpretive errors in 13 (4.8%) cases and screening errors in 42 (15.4%) cases. We demonstrated that the ASC guidelines facilitate cervical CHC. A uniform application of these guidelines would standardize cervical CHCs internationally, provide a scope for the inter-laboratory comparison of data, and enhance self-learning and peer learning.

The article presents retrospective data analysis of a cohort of patients with PKD (n = 41 patients, aged 4 months – 26,5 years, median of age – 5 years 1 month) who were examined at the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology for unspecifid hereditary hemolytic anemia during the period 2013–2020. The study was approved by the Independent Ethics Committee of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. In all patients, the diagnosis was confimed by Next Generation sequencing (NGS). The homozygous mutations in the PKLR gene were found in 10 patients (24.39%), compound heterozygous mutations in 31 patients (75.61%), 77.78% of them were missense mutations. Gender distribution (male:female) was 1:1.73. At least once transfusion of erythrocyte suspension was required to 40 (97.56%) patients. The minimum age at the time of the debut of transfusion dependence was the fist day of life, the maximum was 4 years. Exchange blood transfusion was performed in 13 children, severe normocytic hyperregenerative anemia with transfusion of red blood cells in the fist days of life was noted in 12 children, at the 1st month of life – in 9 children, at the 2nd month of life – in 8 children, at the 3rd month – in 6 children, at the 5th month – in 2 children, at the 1st year – in 1 child, and 2 children underwent single transfusions on the background of infectious episodes at 3 and 4 years respectively. Splenectomy due to high transfusion dependence was performed in 10 patients: transfusion independence was achieved in 5 patients, in 5 – an increase in the interval between blood transfusions. Median of surgical intervention (9 patients): 7 years 4 months, minimum age – 1 year 4 months, maximum – 14 years 4 months. In total, 36 genotypes were described in 41 patients, among them were: c.1529G>A in 3 patients, c.1137_1139del / c.1456C>T – in 2 patients, c.1079G>A/c.1529G>A in 2 patients, c.1130T>C/c.1456C>T in 2 patients, other genotypes occurred once. Two mutations were the most frequent: c.1456C>T (16.67%) and c.1529G>A (16.67%). 19 (46,34%) of patients had previously not described mutations.
