Chemotherapy-based mobilization protocols, though effective, are associated with toxicity, hospitalization, and delay in transplant timing. We developed an algorithm-based protocol for peripheral blood stem cell (PBSC) mobilization using G-CSF alone, with pre-emptive Plerixafor based on peripheral blood CD34+ cell counts.</div></div><div><h3>Methods</h3><div>This retrospective study included MM patients who underwent stem cell collection between July 2013 and November 2023 at Saskatoon Cancer Centre. The mobilization protocol aimed to collect ≥ 4 × 10<sup>6</sup> CD34+ cells/kg, using daily CD34 count monitoring to determine the use of Plerixafor. Predefined thresholds guided the decision for Plerixafor administration and apheresis timing.</div></div><div><h3>Results</h3><div>Out of 176 patients (median age 61 years), 100 % achieved successful mobilization. Preemptive Plerixafor was required in 13.6 % of patients (n = 24), with 1–3 doses administered. The median number of apheresis days was 2 (range: 1–4). The median CD34 yield was 6.4 × 10<sup>6</sup> cells/kg. All patients received high-dose melphalan and underwent autologous transplant, with median neutrophil and platelet engraftment at 12 and 15 days, respectively. All patients were alive at day 100 post-transplant.</div></div><div><h3>Conclusion</h3><div>An algorithm-driven, G-CSF-only mobilization with pre-emptive Plerixafor use based on CD34 counts resulted in 100 % successful collections, early engraftment, minimal plerixafor use, and no mobilization failures. This approach avoids chemotherapy toxicity, optimizes Plerixafor use, and prevents transplant delays.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"65 1","pages":"Article 104304"},"PeriodicalIF":1.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145828560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even in other apheresis modalities used for poisoning and drug overdose, such as therapeutic plasma exchange and red blood cell exchange, few studies have examined the redistribution of such compounds from peripheral tissues back into plasma. In this context, we introduce the “<em>redistribution ratio</em>” (RR) as a novel metric to quantify this phenomenon. Calculated from circulating and collected pools before and after DFPP, RR offers insight into the post-procedural rebound of target analytes. High RR values suggest redistribution from extravascular compartments, commonly seen with lipophilic toxins or compounds that have a high volume of distribution and low plasma protein binding. In contrast, low or negative RR values may reflect limited redistribution due to intracellular sequestration, metabolic elimination, or irreversible tissue binding. To illustrate its clinical relevance, we present RR patterns from a cohort of patients with hyperlipoproteinemia(a) treated with DFPP, showing heterogeneous patterns across a range of environmental toxins. These findings support RR as a valuable complement to conventional pre- and post-procedure concentration metrics, with potential applications in refining DFPP timing and predicting rebound risk. RR may also serve as a surrogate marker for tissue toxin burden, although further validation is needed across broader toxin classes and apheresis platforms.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"65 1","pages":"Article 104369"},"PeriodicalIF":1.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
