Abstract

Peripheral blood stem cell harvesting (PBSCH) is an established general practice; however, recent medical advances have led to diversification in hematopoietic stem cell transplantation and collection. A questionnaire survey on cell therapy and blood cell apheresis was conducted to understand the current situation and identify issues in Japan. A total of 159 facilities/departments responded to the survey. The annual number of autologous PBSCH was "11-25" in 48% and "1-10" in 37% of the centers, while the annual number of allogeneic PBSCH for related transplantation was "1-10" in 60% of the centers and "1-10" in 50% for unrelated transplantation. Collection sites were in the wards (40%), transfusion department (36%), and dialysis unit (26%). The apheresis system was staffed mainly by clinical engineers (67%) and doctors (23%). Primarily, doctors (96%) performed peripheral vascular punctures and were present at all times during collection in 37% of the centers. The Spectra Optia was the equipment most commonly used for apheresis. To freeze the product, 89% of the centers used "CP-1" without a controlled rate freezer. This survey revealed the diversification of collection methods in Japan, with "task shift" emerging as a significant concern.
