Simultaneous Inhibition of BCR-ABL1 Tyrosine Kinase and PAK1/2 Serine/Threonine Kinase Exerts Synergistic Effect against Chronic Myeloid Leukemia Cells.

Tyrosine kinase inhibitors (TKIs) revolutionized the treatment of chronic myeloid leukemia in the chronic phase (CML-CP). However, it is unlikely that they can completely "cure" the disease. This might be because some subpopulations of CML-CP cells such as stem and progenitor cells are resistant to chemotherapy, even to the new generation of TKIs.

Pixantrone, etoposide, bendamustine, rituximab (P[R]EBEN) as an effective salvage regimen for relapsed/refractory aggressive non-Hodgkin lymphoma-Polish Lymphoma Research Group real-life analysis.

Background: Despite a significant improvement in treatment outcomes, 30-40% of aggressive non-Hodgkin lymphomas (NHL) patients are refractory or relapse after the first line therapy. Half of them are not eligible to autologous stem cell transplantation (ASCT) due to failure of platinum-based salvage regimens. Pixantrone is conditionally approved in Europe in patients with R/R aggressive NHL failing at least 2 previous lines of therapy.

Chronic myelogenous leukemia, a still unsolved problem: pitfalls and new therapeutic possibilities.

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder of hematopoietic stem cells. At the molecular level, the disorder results from t(9;22)(q34;q11) reciprocal translocation between chromosomes, which leads to the formation of an oncogenic gene fusion. Instead of progress in the understanding of the molecular etiology of CML and the development of novel therapeutic strategies, clinicians still face many challenges in the effective treatment of patients.
