Extramedullary relapses after allogeneic stem cell transplantation for acute myeloid leukemia: clinical characteristics, incidence, risk factors and outcomes.

Acute myeloid leukemia (AML) relapse after allogeneic hematopoietic cell transplant (allo-HCT) is challenging. Data on extramedullary relapse (EMR) after allo-HCT are limited. We analyzed 215 patients with AML who underwent allo-HCT in our institution between January 2005 and December 2015.

Venous thromboembolism risks and prophylaxis in King Fahad Hospital, Madinah, Saudi Arabia.

Objective: To evaluate the risk factors, physician's compliance, and implementation of the American College of Chest Physicians (ACCP) guidelines for venous thromboembolism (VTE) prophylaxis at our hospital.

Methods: A retrospective cohort study was conducted in King Fahad Hospital, Madinah, Saudi Arabia, from July 2015 to September 2015. We used the ACCP 2012 guidelines to assess the VTE risk and to determine whether patients had received the recommended prophylaxis.

Leukemia relapse after allogeneic bone marrow transplantation: how does chronic graft-versus-host disease influence the pattern and onset of relapse?

We describe a pattern of relapse in 601 patients who received an allogeneic hematopoietic stem cell transplant at our institution for acute or chronic leukemia and myelodysplasia over a period of 18 years. We show a correlation between chronic graft-versus-host disease and extramedullary relapse, suggesting that the expected graft versus leukemia effect in patients with chronic graft-versus-host disease may preferentially maintain marrow remission without preventing relapse in extramedullary sites.

Impact of critical care outreach on hematopoietic stem cell transplant recipients: a cohort study.

Serious morbidity and mortality can occur after hematopoietic SCT (HSCT). Critical care outreach (CCO) can provide timely access to intensive care for hospitalized patients in need of urgent stabilization but has not been examined in HSCT. Rapid Assessment of Critical Events (RACE) team was introduced at our centre January 1, 2005.

Successful treatment of hepatic veno-occlusive disease after myeloablative allogeneic hematopoietic stem cell transplantation by early administration of a short course of methylprednisolone.

Hepatic veno-occlusive disease (VOD) is one of the most common and important regimen-related toxicities observed after hematopoietic stem cell transplantation (HSCT). There are no universally accepted preventative or therapeutic approaches for VOD. We prospectively evaluated the safety and efficacy of a short course of methylprednisolone (MP) in 48 patients undergoing allogeneic HSCT who were diagnosed with hepatic VOD.

Cytogenetics, molecular and ultrastructural characteristics of biphenotypic acute leukemia identified by the EGIL scoring system.

Biphenotypic acute leukemia (BAL) is a rare, difficult to diagnose entity. Its identification is important for risk stratification in acute leukemia (AL). The scoring proposal of the European Group for the Classification of Acute Leukemia (EGIL) is useful for this purpose, but its performance against objective benchmarks is unclear.
