We encourage you to read the next two issues of the journal „Postępów Nauk Medycznych” all of which will be devoted to hematology and bone marrow transplantation. In the last few years we have witnessed the great progress in the knowledge and understanding of pathogenetic mechanisms of many blood cancers and what directly related- the development of new therapeutic options.

I wish to draw your attention for the original paper presenting the results of AHSCT for T-cell lymphoma. The authors collected large group of patients suffering from this rare, poor prognosed lymphoma. The results are encouraging with the estimated 3-year survival of almost 80%.

The yearly number of allogeneic stem cell transplantations (AlloHSCT) from siblings and unrelated donors performed in our Department belongs to the highest in Poland and Europe. I would like to remind you that AlloHSCT still remains only curative method in many neoplastic and benign hematological disorders. The progress made in the care of patients both, before and after transplant resulted in significant decrease of transplant related mortality. In the recent years we have witnessed the increase in the number of transplants performed in older patient population (> 65 years) what is associated with the development of reduced intensity conditioning.
