We previously reported a novel method for allogeneic peripheral blood stem cell harvest (PBSCH) using highly concentrated sodium citrate (HSC; 5.32%), which shortened the procedure time and reduced the need for an AC solution without heparin. In this study, we extended this novel method to autologous PBSCH (auto\u2010PBSCH) and compared it with patients who received auto\u2010PBSCH using normal concentrated sodium citrate (NSC; 2.2%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design and Methods<\/jats:title>\n                    <jats:p>We retrospectively analyzed consecutive auto\u2010PBSCH data obtained using the Spectra Optia continuous mononuclear cell collection mode between May 2017 and May 2025 at our institution.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Leukocytapheresis was performed using NSC in 36 patients and HSC in 22. In the HSC group, patients tended to be younger, had significantly lower body weight, and had significantly fewer hematopoietic tumors as primary diseases compared to the NSC group. After propensity score\u2010matched cohort adjusted for patient background, the total amount of AC solution was significantly lower (694 [range, 77\u20131648] vs. 298\u2009mL [range, 64\u2013797],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.02), and procedure time was significantly shorter (224 [range, 117\u2013395] vs. 181\u2009min [range, 103\u2013309],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.048) in the HSC group.
