For L-asparaginase safety profile improvement a technology of pegylation was lay down and PEG-aspargase drug produced. This drug has less toxic effects and recommended as first-line therapy of acute lymphoblastic leukemia. Drug monitoring for assessment the effectiveness and toxicity of L-asparaginase is optimal. Such therapy individualization helps for L-asparaginase dose finding and decrease frequency and severity of side effects.","PeriodicalId":37536,"journal":{"name":"Oncogematologiya","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135735392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The only generally accepted risk factor for ds is initial leukocytosis. Specific markers confirming ds have not yet been found. A number of studies show that in patients with diagnosed DS, the expression of CD56, CD54, CD2, CD15, CD13, markers of immature granulocytes, β2-integrins was more often found on blast cells. exposure to tretinoin increased the expression of chemokine receptors, chemokines, and cytokines by blast cells and vascular endothelium. The influence exerted by atypical promyelocytes, due to their biological characteristics, on the coagulation system suggests an association between hemostasis state and ds development.

Aplastic anemia proceeds with bone marrow failure and is associated with immunological suppression of normal blood stem cells’ proliferation, which lead to bone marrow aplasia. autoimmune aggression and internal defects of blood stem cell that cause abnormal hematopoiesis are being actively studied. An important role in the pathogenesis of the aplastic anemia is played by instability of telomere length (TL). determination of the initial TL makes it possible to clearly differentiate between the aplastic anemia and dyskeratosis congenita. also, it helps to identify the group of patients with short telomeres for prediction of therapy response. Aim. To investigation the TL of various blood and bone marrow cells in patients with aplastic anemia before treatment. Materials and methods. The group of patients with aplastic anemia was investigated (n = 45). blood donors (n = 32) and bone marrow donors (n = 10) of different ages were included in the reference group. adult patients with dyskeratosis congenita (n = 5) were included in the comparison group. Relative and absolute tl was identified in peripheral blood and bone marrow mononuclear cells, monocytes, lymphocytes by flow-FISH technique (combination of flow cytometry and fluorescence in situ hybridization). Results. Relative and absolute TL was comparable in different blood and bone marrow cells in patients with aplastic anemia before treatment. TL in peripheral blood and bone marrow mononuclear cells wasn’t significantly differed in groups of patients with aplastic anemia and healthy donors. Telomeres in patients with dyskeratosis congenita were identified as “ultrashort” and were significantly shorter than in patients with aplastic anemia. Conclusion. Determination of TL in patients with aplastic anemia is modern examination method, which is a necessary step of differential diagnosis between aplastic anemia and dyskeratosis congenita, which is the disease from group of constitutional bone marrow aplasia. It is preferred to identify the TL in adult patients with aplastic anemia by the flow-FISH. It is necessary to investigate the TL to predict treatment response and to identify risks of developing adverse experiences, which include relapse and clonal evolution.","PeriodicalId":37536,"journal":{"name":"Oncogematologiya","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135885705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the glomerular filtration rate (GFR) dynamics during induction immunopolychemotherapy (PCT) in patients with newly diagnosed diffuse large B-cell lymphoma. Materials and methods. The study included 39 patients with newly diagnosed diffuse large b-cell lymphoma who received specialized treatment in oncohematology department of national medical research centre for oncology (Rostov-on-Don). Patients underwent induction pct according to the R-CHOP (rituximab, doxorubicin, cyclophosphamide, vincristine, prednisolone) regimen with accompanying therapy (allopurinol). blood sampling was carried out at 0, 24, 48, 72, 120 hours and 21 days of the 1 st PCT cycle. GFR was calculated using the SKD-epicre formula (chronic Kidney disease epidemiology collaboration creatinine-based). statistical data processing was carried out using the IBM SPSS statistics 23 program. Results. According to the gfr level before the start of chemotherapy (0 hours), the patients were divided into two groups: group a with GFR > 90 ml / min / 1.73 m 2 and group b with GFR < 90 ml / min / 1.73 m 2 . In group a, there were no significant dynamic changes in the GFR level during PCT. Group B patients reacted more acutely to the administration of pct, which was manifested in an even greater decrease in the gfr level at 48 hours of PCT, and at 120 hours of PCT, the GFR approached the optimal values. on the 21 st day from the start of the 1 st pct course, the studied indicator returned to its initial values at 0 hour. further, the patients of these groups were divided into subgroups depending on the disease stage: group a consisted of 12 people with stages I–II and 15 people with stages III–IV. In group B, there were an equal number of patients with stages I–II and III–IV – 6 people. In group a, in patients with stages I–II and III–IV before the start of PCT (0 hours) and during PCT, there were no differences in the GFR level dynamics. In group B, patients with stages I-II and III–IV had similar GFR before the start of PCT, and during treatment, they reflected the previously noted general group trend in GFR level dynamics. Conclusion. The study found that in patients with initially low GFR level, a further, even more pronounced decrease in GFR during pct is observed. at the same time, the absence of significant differences in GFR level depending on disease stage allows us to conclude that the leading role is not so much the stage of the disease and tumor volume, but rather the initial functional status of the kidneys in the development of renal dysfunction in patients with diffuse large B-cell lymphoma during R-CHOP therapy.","PeriodicalId":37536,"journal":{"name":"Oncogematologiya","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135885559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our work, we evaluate the association of high leukocyte counts with individual mutations, as well as their total contribution to the development of leukocytosis in AML. The results obtained should improve our understanding of pathogenic mechanisms leading to the leukocytosis in AML. Aim. To study the genetic landscape of AML with leukocytosis. Materials and methods. The laboratory data of 214 AML patients admitted to the National Medical Research Center for Hematology (Moscow) from 2010 to 2022 were retrospectively examined. Real-time PCR, capillary electrophoresis and NGS (next generation sequencing) methods were used to detect mutations of FLT3, NPM1, CEBPA, IDH1/2, DNMT3A, TET2 genes, and CBFB::MYH11, RUNX1::RUNX1T1 chimeric gene transcripts. Results. Mutations of the FLT3 gene (odds ratio 5.45; p < 0.0001), inv(16)/ CBFB::MYH11 (odds ratio 10.03; p = 0.0009) are most associated with leukocyte counts higher than 30 × 10 9 / L in the debut of AML.

In the group of patients with intermediate cytogenetic risk bearing only IDH1/2, DNMT3A , and TET2 gene mutations, leukocyte counts at AML debut were significantly lower, whereas the most pronounced leukocytosis was observed in patients with a combination of driver mutations with IDH1/2, DNMT3A , and TET 2 gene mutations or FLT3, NPM1 , and CEBPA gene mutations. Conclusion. In addition to the individual effect of certain genetic lesions and cytogenetic aberrations on the proliferative potential of tumor cells, there is a total contribution of various types of genetic events to the development of leukocytosis in AML. High leukocyte counts at the time of AML manifestation in patients with intermediate cytogenetic risk can serve as an indirect marker of the presence of a large number of genetic aberrations with a combination of IDH1/2, DNMT3A , and TET2 gene mutations or FLT3, NPM1 , and CEBPA gene mutations.","PeriodicalId":37536,"journal":{"name":"Oncogematologiya","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135885706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Classical Hodgkin’s lymphoma is a B-cell lymphoproliferative disease, the tumor substrate of which is Berezovsky–Reed–Sternberg cells, characterized by CD30, PAX-5, CD15 expression and the absence of CD3, CD45. In some cases, tumor cells express CD20. modern anticancer therapy has increased the survival probability for most patients, not only with early but also with advanced stages of classical Hodgkin’s lymphoma. Such successes are mainly due to the distribution of patients into prognostic groups and the choice of an appropriate treatment regimen. tumor infiltration of the bone marrow suggests assigning patients to the advanced stages group, followed by the choice of an intensive therapy program. Aim. To determine the bone marrow involvement frequency according to positron emission tomography combined with computed tomography (PET/CT), with 18 F-fluorodeoxyglucose (FDG) and bone marrow trephine biopsy (bmtb), to compare the results obtained with primary tumor immunophenotype and bone marrow cellular composition, and to identify of prognostic risk factors. Materials and methods. The study included 107 patients with newly diagnosed classical Hodgkin’s lymphoma, who underwent a diagnostic examination at the moscow research institute of oncology named after P. A. Herzen – a branch of the National Medical Research Center for Radiology and the “Lapino” clinical Hospital from 2015 to 2022, followed by anticancer therapy and further follow-up.

All patients underwent a morphological and / or IHC study of BMTB and the majority underwent aspiration biopsy and PET/CT with 18 F-FDG. Results. The most common histological variant of classical Hodgkin’s lymphoma was nodular sclerosis (86.9 %). The majority of patients (51.4 %) were assigned to the advanced stage prognostic group. bone marrow tumor infiltration was statistically significantly more frequently diagnosed during PET/CT with 18 F-FDG compared with the results of the BMTB – in 27.1 % and 12.1 % of cases, respectively (p < 0.05). when comparing the results of both diagnostic methods, it was found that in 17.1 % of cases, bone marrow infiltration, detected during PET/CT, was not confirmed by IHC examination of the trephine biopsy. In addition, it was found that the majority of cases with CD20 +/± and CD15 +/± expression in the primary tumor were observed in the group of patients without bone marrow involvement. when assessing the cellular composition of bone marrow aspirates, it was revealed that in patients with bone marrow tumor infiltration, an increase in cellularity and megakaryocytes number along with a decrease in the plasma cells number is observed.
