Methods: This retrospective study included 152 adult patients who received auto-HSCT between 2010 and 2024. D-dimer and fibrinogen levels were documented prior to the transplant. Survival analyses were performed with Kaplan-Meier curves and Cox regression methods. ROC analysis provided cut-off values. Results: The D-dimer and fibrinogen cut-off levels of >860 ng/ml and >448 mg/dl, respectively, were statistically significant with increased rates of relapse and mortality. Mortality was independently predicted by D-dimer and fibrinogen (HR: 96.74 and 5.478) and relapse (HR: 24.254 and 6.921). Increased levels of the markers significantly reduced the five-year overall survival. Conclusion: Auto-HSCT patients with elevated D-dimer and fibrinogen have unfavorable prognoses and poor outcomes. The inexpensive nature of these biomarkers allows greater ease in establishing risk stratification for targeted pre-transplant planning.}, number={4}, publisher={MediHealth Academy Yayıncılık}, organization={The authors received no financial support for the research, authorship, and/or publication of this article.}
