This study evaluated the prognostic capability of the Day 100 NKC/CD14(+)HLA-DRDIM ratio in lymphoma patients who underwent autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT). The results showed that a Day 100 NKC/CD14(+)HLA-DRDIM ratio >= 1.67 was associated with better overall survival and progression-free survival.
Introduction: The infusion of autograft Natural Killer Cells (NKC)/CD14(+)HLA-DRDIM ratio is a predictor of survival in lymphoma patients undergoing autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT). This study evaluated if the Day 100 NKC/CD14(+)HLA-DRDIM ratio still functions as a prognostic immune-biomarker.Methods: This was a retrospective, single-institution, cohort analysis including 107 patients in this study that had clinical assessment at Day 100 post-APBHSCT from our prior phase III trial. We evaluated the prognostic ability of the Day 100 NKC/CD14(+)HLA-DRDIM ratio to predict overall survival (OS) and progression-free survival (PFS) using Cox regression model for outcome analysis and survival by Kaplan-Meier method.Results: The median follow-up from day 100 was 94.7 months (range 4.83-158.1 months) for the entire cohort. Patients with a Day 100 NKC/CD14(+)HLA-DRDIM ratio >= 1.67 experienced better OS and PFS versus those with a Day 100 NKC/CD14(+)HLA-DRDIM ratio <1.67: median OS was not reached versus 49.7 months, the 5-year OS rates were 91% (95% CI, 81%-96%) versus 40% (95% CI, 27%-55%), p < .0001, respectively; and median PFS was not reached versus 23.5 months, the 5-year PFS rates were 66% (95% CI, 55%-81%) versus 21% (95% CI, 15%-40%), p < .0001, respectively. Day 100 NKC/CD14(+)HLA-DRDIM ratio was an independent predictor for OS and PFS in the multivariate analysis.Conclusions: Day 100 NKC/CD14(+)HLA-DRDIM ratio is a prognostic immune-biomarker in lymphoma patients post- APBHSCT.
