On November 28, 1984, a team of Polish doctors led by Professor Wiesław Jędrzejczak performed Poland’s first successful bone marrow transplant.
The groundbreaking procedure, conducted at the Central Clinical Hospital of the Military Medical Academy in Warsaw, involved a six-year-old girl with Diamond-Blackfan anemia receiving marrow from her younger sister. Despite limited resources, the team developed innovative methods and a now-standard preparation technique using chemotherapy instead of full-body radiation.
