Methods: One hundred and four MDS patients with a median International Prognostic Scoring System (IPSS) score of 0.

The Outcomes of Chronic Myeloid Leukemia Patients With Molecular Warning Responses During Imatinib Treatment According to the European LeukemiaNet 2013 Recommendations.

Background: In the European LeukemiaNet (ELN) 2013 recommendations, chronic myeloid leukemia (CML) patients with warning response (WR) were suggested to be monitored closely continuing with the same tyrosine kinase inhibitor (TKI). Differently, the guidelines of the National Comprehensive Cancer Network considers switching to another TKI as an option.

Patients And Methods: We retrospectively evaluated 73 CML patients receiving first-line imatinib, who were followed and managed in accordance with ELN recommendations.

Vincristine as an Adjunct to Therapeutic Plasma Exchange for Thrombotic Thrombocytopenic Purpura: A Single-Institution Experience.

Background: Thrombotic thrombocytopenic purpura is a potentially life-threatening condition. Although the introduction of therapeutic plasma exchange has reduced mortality rates from over 90% to 10%-20%, approximately 40% of patients relapse, and outcomes may be fatal in refractory patients. There is clearly a need for additional therapeutic approaches.

Deep sequencing of BCR-ABL1 kinase domain mutations in chronic myeloid leukemia patients with resistance to tyrosine kinase inhibitors.

Tyrosine kinase inhibitor (TKI) therapy is the current treatment of choice for patients with chronic phase chronic myeloid leukemia (CML) leading to rapid and durable hematological as well as molecular responses. However, emergence of resistance to TKIs has been the major obstacle to treatment success on long term. In this regard kinase domain mutations are the most common mechanism of therapy failure.

Results: Although the highest overall response rate (ORR) was observed in patients receiving 2-CdA upfront, ORRs were comparable in the 2-CdA, INF-α, and splenectomy subgroups.

Third-line treatment with second-generation tyrosine kinase inhibitors (dasatinib or nilotinib) in patients with chronic myeloid leukemia after two prior TKIs: real-life data on a single center experience along with the review of the literature.

Objectives: Newer tyrosine kinase inhibitors (TKIs) (bosutinib, ponatinib) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) can be utilized as a salvage therapy in patients with chronic myeloid leukemia (CML) who failed two lines (imatinib → nilotinib or imatinib → dasatinib) of TKI therapy. However, these TKIs are not available in many countries and not all patients can undergo allo-HSCT.

Methods: In this study, CML patients who received dasatinib or nilotinib as a third-line treatment were retrospectively evaluated.

Outcomes of Chronic Myeloid Leukemia Patients With Early Molecular Response at 3 and 6 Months: A Comparative Analysis of Generic Imatinib and Glivec.

Background: The molecular response at 3 months of the original imatinib (OI) in patients with chronic myeloid leukemia has prognostic significance; however, this has never been tested for generic imatinib (GI).

Patients And Methods: We evaluated the BCR-ABL1 [international reporting scale (IS)] transcript levels at 3 and 6 months to determine whether an early molecular response (EMR) had a prognostic effect on the outcome among chronic myeloid leukemia patients receiving GI. Ninety patients were divided into 2 groups, according to the imatinib they received, as OI (group A) and GI (group B).

Clinical Outcomes Related to the Use of Bendamustine Therapy for Multiple Myeloma Patients Relapsed/Refractory to Immunomodulatory Drugs and Proteasome Inhibitors.

Objective: Multiple myeloma patients who are relapsed or refractory to both proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs) have been reported to have poor outcomes. Bendamustine has been reported to have an antitumor effect in newly diagnosed as well as relapsed/refractory multiple myeloma (RRMM). The aim of this retrospective study was to evaluate the efficacy of bendamustine therapy in heavily pretreated MM patients who were refractory to PIs and IMiDs.
