Background: Nutritional disorders in cancer patients, including lymphoproliferative neoplasms, occur with varying frequency.
Objectives: The primary aim of the study was to analyze the changes in the nutritional status of patients with lymphoproliferative neoplasms following first-line chemotherapy.
Materials And Methods: 46 patients, with a median age of 62 years, participated in a prospective single-center study. Their demographic, biochemical and clinical features were analyzed. The study consisted of several stages that were conducted at two time points. P values < 0.05 were considered statistically significant.
Results: The study included patients with multiple myeloma (48%), non-Hodgkin's lymphoma (28%) or chronic lymphocytic leukemia (24%). After the end of the first-line chemotherapy, a decrease in the concentration of albumin (p = 0.04), transferrin (p = 0.38) and total cholesterol (p = 0.76) were found. Statistically greater unintended weight loss occurred before treatment initiation (p < 0.001). Moreover, a significant decrease in the mean values of the phase angle (p < 0.01) was noted.
Conclusions: Most patients before the oncological therapy did not show clinical or biochemical symptoms of malnutrition. However, after the treatment was completed, the parameters of the nutritional status showed its deterioration.

Introduction: Castleman disease is a rare lymphoproliferative disorder, subdivided into three types: unicentric Castleman disease, idiopathic multicentric Castleman disease and human herpesvirus-8 (HHV8) associated multicentric Castleman disease. The retroperitoneum comprises only 13 % of the cases.

Background: In vivo T-cell depletion with antithymocyte globulin (ATG), especially at high-doses has been shown to be associated with increased incidence of infections after allogeneic hematopoietic stem cell transplantation (HSCT). However, it remains unclear whether ATG, even at low-doses increases the risk of posttransplant infections in the high-risk HSCT setting.
Patients And Methods: We conducted a single-center retrospective study of viral and fungal infections early after transplantation, using the data from 82 patients with hematological malignancies.

Chronic lymphocytic leukemia is a malignant lymphoproliferative disorder for which primary or acquired drug resistance represents a major challenge. To investigate the underlying molecular mechanisms, we generate a mouse model of ibrutinib resistance, in which, after initial treatment response, relapse under therapy occurrs with an aggressive outgrowth of malignant cells, resembling observations in patients. A comparative analysis of exome, transcriptome and proteome of sorted leukemic murine cells during treatment and after relapse suggests alterations in the proteasome activity as a driver of ibrutinib resistance.

Sarcoidosis and lymphoma share immunopathological characteristics that suggest a complex, interconnected relationship. This article examines the multi-faceted mechanisms linking sarcoidosis to lymphoma, a phenomenon called sarcoidosis-lymphoma syndrome (SLS). SLS is hard to diagnose, requiring distinct criteria and imaging to differentiate overlapping features and histological differences.

Methotrexate (MTX), an antimetabolite targeting certain autoimmune conditions and various hematologic malignancies, has been associated with iatrogenic lymphoproliferative disease (LPD) primarily of B-cell lineage. Less commonly are T-cell neoplasms where primary skin involvement is considered rare. Three cases were encountered in the medical practice of one of the authors.
