The significance of upfront autologous stem cell transplantation for high-intermediate/high-risk stage IV diffuse large B-cell lymphoma.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common (30%-35%) type of B-cell lymphoma. Only about 60% of all newly diagnosed advanced-stage DLBCL can be completely treated with x6 R-CHOP. High-dose chemotherapy (HDCT) followed by autologous hematopoietic stem cell transplantation in the first remission (upfront auto-HSCT) can serve as an option to improve a prognosis in these patients.

AuNP Aptasensor for Hodgkin Lymphoma Monitoring.

A liquid biopsy based on circulating small extracellular vesicles (SEVs) has not yet been used in routine clinical practice due to the lack of reliable analytic technologies. Recent studies have demonstrated the great diagnostic potential of nanozyme-based systems for the detection of SEV markers. Here, we hypothesize that CD30-positive Hodgkin and Reed-Sternberg (HRS) cells secrete CD30 + SEVs; therefore, the relative amount of circulating CD30 + SEVs might reflect classical forms of Hodgkin lymphoma (cHL) activity and can be measured by using a nanozyme-based technique.

Efficacy of Gemcitabine on Intracranial Erlich Tumor and its Determinants.

Gemcitabine is quite effective in the treatment of brain tumors, although this drug has a limited ability to overcome the blood-brain barrier (BBB). Aim of study is to assess the therapeutic efficacy of gemcitabine and other drugs with different permeability of BBB in the model of intracranial tumor. The therapeutic activity of gemcitabine, carmustine, cyclophosphamide and cisplatin was studied in mice with intracranially implanted Ehrlich tumor, and also gemcitabine in various doses - with intramuscularly implanted tumor.

Enchancement of Toremifene Anti-Tumor Action by Metformin and Unusual Side Effect of Toremifene in Male Transgenic Mice with HER2-Positive Breast Tumor.

HER2-positive breast tumors are found in 25-30% of patients with breast cancer and are characterized by aggressive course and reduced sensitivity to both chemotherapy and hormone therapy. The aim of the work was to study the possibilities of enhancing the therapeutic effect of anti-estrogen drug toremifene by combining it with biguanide, metformin, on the HER2-positive breast cancer model in FVB/N HER-2/neu transgenic mouse. Male FBV/N mice with intramuscularly transplanted HER2-positive mammary gland tumor from a female mouse of the same strain have been given toremifene (30 mg/kg, orally daily) or metformin (100 mg/kg, orally daily) that had a moderate antitumor effect (decrease the area under the kinetic curve of tumor growth by 1.
