EXPRESSION PROFILE OF miR-145, -182, -21, -27a, -29b, and -34a IN BREAST CANCER PATIENTS OF YOUNG AGE.

Background: Breast cancer (BC) in young women remains a significant public health concern. While progress has been made in understanding the etiology, diagnosis, and treatment of BC in this population, challenges persist. The identification and utilization of prognostic biomarkers offer valuable tools for tailoring treatment strategies and improving outcomes for BC patients.

A RARE UTERINE TUMOR: DISSEMINATED PERITONEAL LEIOMYOMATOSIS. CLINICAL OBSERVATIONS.

Background: Disseminated peritoneal leiomyomatosis (DPL) is an extremely rare benign disease characterized by widespread lesions of the abdominal cavity, pelvis, and retroperitoneal space with tumor nodules of varying size and number, which are benign neoplasms consisting of smooth muscle fibers in their histological structure.

Aim: To analyze clinical cases of DPL with a concise review of the current state of the DPL diagnosis and treatment.

Materials And Methods: We analyzed 5 clinical cases of DPL of female patients aged 39-50 years (mean age 46.

PATTERN OF MMP2 AND MMP9 EXPRESSION DEPENDS ON BREAST CANCER PATIENTS' AGE.

Background: Despite the large number of studies devoted to the study of the features of tumor microenvironment in breast cancer (BCa), presently there is no consensus on the features of MMP-2 and MMP-9 expression in the tumor tissue of BCa patients depending on the age. The aim of the study was to investigate the relationship between MMP-2 and -9 expression at the protein and mRNA levels in BCa tissues and the clinical and pathological features of BCapatientsin different age groups.

Materials And Methods: The expression level of MMP-2 and -9in the BCa tissue of patients of two age groups (< 45 years and > 45 years) was studied using the bioinformatics method (UALCAN database), immunohistochemical method, and real-time PCR.

Distribution of lymphoma subtypes in Ukraine according to the WHO 2016 classification.

The Ukrainian Lymphoma Registry (ULR) was established in 2019 with the aim of monitoring the quality of diagnosis, staging, and treatment of lymphoma in Ukraine. Between September 2019 and October 2021, 546 patients with newly diagnosed lymphoma were prospectively registered. All cases were diagnosed according to the 2016 updated WHO lymphoma classification.

Effects induced by a 50 Hz electromagnetic field and doxorubicin on Walker-256 carcinosarcoma growth and hepatic redox state in rats.

We compare the effects of an extremely low-frequency electromagnetic field (EMF) with the chemotherapeutic agent doxorubicin (DOX) on tumor growth and the hepatic redox state in Walker-256 carcinosarcoma-bearing rats. Animals were divided into five groups with one control (no tumor) and four tumor-bearing groups: no treatment, DOX, DOX combined with EMF and EMF. While DOX and DOX + EMF provided greater inhibition of tumor growth, treatment with EMF alone resulted in some level of antitumor effect ( < .
