Unlabelled: Cancer cells can aberrantly express various markers, including transferrin receptor 1 (CD71) and 1-integrin molecules. Their role in invasion, migration and metastasis has been demonstrated. Determination of their expression in breast cancer (BC) may be an important point to characterize the clinical course of the tumor and prognosis of the disease.

Bacterial infections are usually found in the stomach and the first part of the small intestine in association with various pathologies, including ulcers, inflammatory diseases, and sometimes cancer. Treatment options may include combinations of antibiotics with proton pump inhibitors and anti-inflammatory drugs. However, all of them have high systemic exposure and, hence, unfavorable side effects, whereas their exposure in stomach mucus, the predominant location of the bacteria, is limited.

Objectives: Radioactive iodine therapy is considered for patients with certain clinicopathological factors that predict a significant risk of recurrence, distant metastases of thyroid cancer or disease-specific mortality. The aim of the study was to investigate the association between polymorphisms of genes, products of which are involved in the processes of DNA damage response and autophagy, and the adverse reactions of radioiodine therapy in thyroid cancer patients.

Methods: The study included 181 patients (37 men, 144 women; median age 56 [41; 66.

Objectives: The present study investigated the analysis of adverse drug reactions (ADRs) to tamoxifen (TAM) in breast cancer patients in relation to the carriage of genetic polymorphisms of genes encoding enzymes of CYP system and transporters of P-glycoprotein (Pg) and predictive models based on it.

Methods: A total of 120 women with breast cancer taking adjuvant TAM were examined for the gene polymorphisms such as , , , , , and (). Allelic variants were determined using the real-time polymerase chain reaction method.

Autoimmune hemolytic anemia (AIHA) and pure red cell aplasia (PRCA) are common complications of CLL. The optimal treatment of steroid refractory AIHA/PRCA is not well established. We conducted a multicenter study of ibrutinib and rituximab in patients with relapsed/refractory to steroids AIHA/PRCA and underlying CLL.

There is accumulating evidence that anemia and iron deficiency, thrombocytopenia, blood loss and coagulopathy are independent risk factors for adverse patient outcomes in oncology and other settings. Patient blood management (PBM) aims to address these factors by managing and preserving a patient's blood. PBM improves patient health, but also reduces resource utilization, including use of allogeneic blood components, which is another risk factor for adverse outcomes.

Monoclonal gammopathy of renal significance (MGRS) is a new nosology in modern nephrology and oncohematology. MGRS is defined as kidney injury due to nephrotoxic monoclonal immunoglobulin produced by the B-cell line clone which does not reach the hematological criteria for specific treatment initiation. Monoclonal proteins pathological effects on kidney parenchyma result in irreversible decline of kidney function till the end stage renal disease that in line with the position of International Consensus of hematologists and nephrologists determinates critical necessity for clone specific treatment in patients with MGRS despite the absence of hematological indications for treatment initiation.

Article Synopsis
  • BCD-020 is a proposed biosimilar to rituximab, demonstrating similar quality and effectiveness in treating adult patients with indolent lymphomas in a multicenter clinical trial.
  • The study involved 174 patients, showing overall response rates of 44.71% for BCD-020 and 41.89% for rituximab, indicating equivalent efficacy between the two treatments.
  • Both drugs had comparable safety profiles, with no unexpected adverse reactions and similar patterns in the depletion of B-cells, confirming pharmacokinetic equivalence.

Breast cancer (BC) is a heterogeneous tumor, the biological characteristics of which vary with its growth and progression. Information on key tumor receptors (ER, PR, HER2, and Ki-67) is the basis for individualizing the diagnostic and treatment algorithm at all BC stages; however, the feasibility of biopsy of distant metastases and the re-testing of the biological subtype of BC in its suspected progression are being actively discussed in clinical practice. This review presents an update on the features of metastasis in different biological BC subtypes and assesses the clinical and prognostic role of biopsy of distant metastases in the lung, bones, liver, and brain.

Chronic lymphocytic leukemia (CLL) mainly affects older people: the median age at diagnosis is > 70 years. Elderly patients with CLL are heterogeneous with regard both to the biology of their disease and aging. Following the diagnosis of CLL in an elderly individual, careful risk assessment is essential when treatment options are evaluated.

Previous randomized trials have demonstrated that rituximab maintenance (R-maintenance) can prolong time to progressive disease in patients with follicular lymphoma (FL). The phase IIIb MAXIMA study (NCT00430352) was a large prospective evaluation of R-maintenance in a daily care setting. The primary objective was safety.
