Abstract

The number of newly diagnosed haematological malignancies in Polish adults and children is about 9,000 a year, which constitutes about 5.5% of all malignancies in the country. Adult patients with haematological malignancies are diagnosed and treated in 42 institutions in Poland. The scientific and educational support for this activity is provided under the umbrella of the Polish Society of Haematologists and Transfusiologists (PTHiT, Polskie Towarzystwo Hematologów i Transfuzjologów), the Polish Adult Leukemia Group (PALG), the Polish Lymphoma Research Group (PLRG), the Polish Myeloma Study Group (PMSG), the Polish Myeloma Consortium (PMC), and consultants in haematology. The aim of this position paper is to present the current status and progress in therapy of haematological malignancies in Polish haematology adult centres, focusing on the activity of PALG, PLRG, and PMSG. The achievements of Polish haemato-oncology at the beginning of the third decade of the 21st century are set out in this paper. Polish haemato-oncology today has an important international position based on contributions to the development of knowledge, international cooperation, and a high quality of patient care. In many instances, clinical trials run by Polish collaborative groups have influenced international standards. Polish haematologists have been the authors of treatment recommendations, and their research has indicated areas for further research.
