Role of Imaging in Multiple Myeloma: A Potential Opportunity for Quantitative Imaging and Radiomics?

Multiple myeloma (MM) is the second most prevalent hematologic malignancy, particularly affecting the elderly. The disease often begins with a premalignant phase known as monoclonal gammopathy of undetermined significance (MGUS), solitary plasmacytoma (SP) and smoldering multiple myeloma (SMM). Multiple imaging modalities are employed throughout the disease continuum to assess bone lesions, prevent complications, detect intra- and extramedullary disease, and evaluate the risk of neurological complications.

A retrospective analysis was performed to evaluate the efficacy and safety of VEN-R within the Polish Adult Leukemia Study Group (PALG) centers. The study group included 117 patients with RR-CLL (with early relapse after immunochemotherapy or bearing TP53 aberrations) treated with VEN-R in 2019-2023 outside clinical trials.

COVID-19 in Adult Patients with Hematological Malignancies-Lessons Learned after Three Years of Pandemic.

The COVID-19 pandemic is undoubtedly the most difficult health challenge of the 21st century with more than 600 million laboratory-confirmed SARS-CoV-2 infections and over 6.5 million deaths worldwide. The coronavirus pandemic contributed to rapid development of mRNA vaccines, which, along with new antiviral drugs, have been the subject of extensive research for many decades.

Molnupiravir is effective in patients with haematological malignancies.

Patients with hematologic malignancies are particularly vulnerable to severe infectious complications. SARS-CoV-2 infection is associated with a high risk of severe course and death in this patient population. In addition, immune deficits associated with both the blood cancer and the treatment used make vaccination against SARS-CoV-2 less effective than in immunocompetent individuals.

Early efficacy and safety of obinutuzumab with chemotherapy in previously untreated patients with follicular lymphoma: A real-world retrospective report of the Polish Lymphoma Research Group.

Background: The first-line obinutuzumab-based immunochemotherapy improves the outcome of patients with follicular lymphoma (FL) compared with rituximab-based regimens. However, infusion-related reactions occur in almost half of patients during the 1st obinutuzumab administration.

Objectives: The study aimed to evaluate the early effectiveness and safety of obinutuzumab-based induction regimens in a real-world setting.

Secondary malignancies and survival of FCR-treated patients with chronic lymphocytic leukemia in Central Europe.

This is the first large-scale cross-country analysis of patients with chronic lymphocytic leukemia (CLL) aimed to evaluate the incidence, types, and key prognostic factors of secondary malignancies, and to assess the impact on overall survival based on retrospective claims data from three Central European countries. We analyzed 25,814 newly diagnosed CLL patients from Czechia, Hungary, and Poland; 10,312 (39.9%) patients were treated for CLL in study periods between 2004 and 2016.

Response to anti-SARS-CoV-2 mRNA vaccines in multiple myeloma and chronic lymphocytic leukemia patients.

Multiple myeloma (MM) and chronic lymphocytic leukemia (CLL) patients have increased morbidity and mortality rates of COVID-19 due to immunosuppression associated with the disease and ongoing therapy. The same immune impairment accompanying CLL and MM also affects suboptimal vaccine response. The study assessed the effectiveness of the humoral and T cell-mediated immunity following mRNA COVID-19 vaccination (using either BNT162b2 or mRNA-1273) in short-term (2-5 weeks after second dose) and long-term follow-up (12 weeks after vaccination).

PI3K Inhibitors for the Treatment of Chronic Lymphocytic Leukemia: Current Status and Future Perspectives.

Phosphoinositide 3-kinases (PI3Ks) signaling regulates key cellular processes, such as growth, survival and apoptosis. Among the three classes of PI3K, class I is the most important for the development, differentiation and activation of B and T cells. Four isoforms are distinguished within class I (PI3Kα, PI3Kβ, PI3Kδ and PI3Kγ).

Outcome of SARS-CoV-2-Infected Polish Patients with Chronic Lymphocytic Leukemia.
