We report a summary of 105 decision-making information sessions (DISs) for unrelated donor consent in the Japan Marrow Donor Program (JMDP) between 2004 and 2019. We retrospectively compared data from our cases with those of cases of JMDP during the same period. The median age of our patients during the 15-year period was 37 years, and the male-to-female ratio was 1.8 to 1. During that period, 18,515 people participated in the JMDP; their median age was 37 years, and the male-to-female ratio was 2.0 to 1. The coordination period included confirmatory typing (CT), DISs, and hematopoietic cell transplantation (HCT). We found a significant difference (P=0.004) in the period from CT to DISs between our cases (38.7 days) and the JMDP cases (45.3 days) but no difference in the period from DISs to HCT between the two groups. With regard to the day of the week for the DISs, 36.2% of our cases were conducted on Saturdays and Sundays, in comparison with 6.4% of the JMDP cases. We believe that selecting Saturdays and Sundays as possible dates for the DISs may have led to a shorter coordination period.
