Abstract Peripheral blood infused total autograft absolute lymphocyte count (A-ALC) correlates with day 15 absolute lymphocyte count and is an independent prognostic factor for survival after autologous stem cell transplantation (ASCT) for non-Hodgkin lymphoma (NHL). Factors to enhance A-ALC collections are not well defined. We hypothesize that the number of peripheral blood apheresis collections (PBAC) directly correlates with A-ALC. 190 consecutive NHL patients who underwent ASCT at the Mayo Clinic between 1993 and 2001 were analyzed. The primary end point of the study was to assess the correlation between the number of PBAC and A-ALC. The secondary end point was to determine if the number of PBAC affected survival post-ASCT. Of the 190 patients, 18 patients underwent 1 PBAC, 23 patients 2 PBAC, 50 patients 3 PBAC, 37 patients 4 PBAC, 50 patients 5 PBAC, and 12 patients had ≥ 6 PBAC. There was no association between the number of PBAC and the number of CD34+ stem cells collected (p= 0.25). A strong association between number of PBAC and A-ALC (Kruskall Wallis test, p <0.0001)(Figure 1) was identified. Using a cut-off of 4 PBAC, superior overall survival (OS) and progression-free survival (PFS) were observed for patients that underwent 4 PBAC or more compared to patients that underwent less than 4 PBAC (86 months vs 18 months, p <0.0001; 76 months vs 10 months, p <0.0001, respectively). Multivariate analysis demonstrated PBAC ≥ 4 is an independent prognostic factor for OS (RR = 0.654, 95%CI: 0.529–0.804, p< 0.0001) and for PFS (RR = 0.682, 95%CI: 0.561–0.826, p< 0.0001) when compared with other significant factors including performance status, lactate dehydrogenase and extra nodal disease. These data suggest that increasing the number of PBAC beyond the minimum number required to meet CD34+ collection targets may result in improved overall and progression-free survival mediated by an increase in autograft absolute lymphocyte count.

Abstract The autograft absolute lymphocyte count (A-ALC) ≥ 0.5 x 10 9 cells/kg is a survival prognostic factor for lymphoma patients undergoing autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT). However, the A-ALC ≥ 0.5 x 10 9 cells/kg has not been tested as prognostic factor against double hit/triple hit lymphomas (DHL/THL). Thus, we set up to investigate if A-ALC ≥ 0.5 x 10 9 cells/kg is a prognostic factor for overall survival (OS) and progression-free survival (PFS) for DHL/THL post-APBHSCT. From January 2012 until December 2020, we identified 77 DHL/THL patients treated with APBHSCT. All patients required to have the diagnosis of DHL/THL by FISH for rearrangements of MYC, BCL2, and BCL6. Of the 77 patients, 62 patients were classified as DHL and 15 patients as THL. Of the DHL, 82 % (52/68) had the MYC/BCL2 and 16% (10/62) the MYC/BCL6 rearrangements. Dividing the cohort into two groups (A-ALC ≥ 0.5 x 10 9 cells/kg and A-ALC &lt; 0.5 x 10 9 cells/kg), both groups were balanced in regard to de novo versus transformed histology (p = 0.3), cell of origin (p = 0.6), DHL and THL (p = 0.6), MYC/BCL2; MYC/BCL6; and MYC/BCL2/BCL6 rearrangements (p = 0.6), first line chemotherapy (p = 0.2), salvage chemotherapy (p = 0.5), disease status prior to APBHSCT (CR1, CR, and PR) (p = 0.07), stem cell mobilization (Plerixafor versus not) (p = 0.6), and infusion of CD34 count (p = 0.2). With a median follow-up of 20.4 months (range, 0.4-94.5 months) for the entire cohort and with a median follow-up of 33.5 months (range, 3.5-94.5 months) for the patients that remained alive, DHL/THL patients infused with A-ALC ≥ 0.5 x 10 9 cells/kg experienced superior OS (HR = 0.251, 95%CI 0.117-0.539, P &lt; 0.0004) and PFS (HR = 0.347, 95%CI 0.160-0.753, P &lt; 0.007). The 5-year OS rates for the A-ALC ≥ 0.5 x10 9 cells/kg group was 73% (95% confidence interval [CI], 52%-87%) and for the A-ALC &lt; 0.5 x10 9 cells/kg group was 18% (95% CI, 7%-39%) (Figure 1A). The 5-year PFS rates for the A-ALC ≥ 0.5 x10 9 cells/kg group was 73% (95% CI, 59%-85%) and for the A-ALC &lt; 0.5 x10 9 cells/kg group was 13% (95% CI, 5%-33%) (Figure 1B). Multivariate analysis showed that A-ALC was an independent predictor for OS (HR =0.178, 95%CI 0.052-0.614, p &lt;0.005) and PFS (HR = 0.400, 95%CI 0.189-0.850, p &lt;0.02). Our study showed that A-ALC is a prognostic factor for survival in DHL/THL patients undergoing APBHSCT. Our current practice for all lymphoma patients is not only to collect enough stem cell for hematologic engraftment, but also A-ALC ≥ 0.5 x 10 9 cells/kg to improve clinical outcomes post-APBHSCT.

Abstract Autologous stem cell transplantation (ASCT) improves survival in patients with previously untreated multiple myeloma (MM) and relapsed, chemotherapy-sensitive, aggressive non-Hodgkin lymphoma (NHL). Lower relapse rates seen in allogeneic stem cell transplantation have been related to early absolute lymphocyte count (ALC) recovery as a manifestation of early graft-verus-tumor effect. In ASCT, the relation between ALC recovery and clinical outcomes in MM and NHL was not previously described. This is a retrospective study of patients with MM and NHL who underwent ASCT at the Mayo Clinic between 1987 and 1999. The ALC threshold was determined at 500 cells/μL on day 15 after ASCT. The study identified 126 patients with MM and 104 patients with NHL. The median overall survival (OS) and progression-free survival (PFS) times for patients with MM were significantly longer in patients with an ALC of 500 cells/μL or more than patients with an ALC of fewer than 500 cells/μL (33 vs 12 months,P &lt; .0001; 16 vs 8 months, P &lt; .0003, respectively). For patients with NHL, the median OS and PFS times were significantly longer in patients with an ALC of 500 cells/μL or more versus those with fewer than 500 cells/μL (not reached vs 6 months, P &lt; .0001; not reached vs 4 months,P &lt; .0001, respectively). Multivariate analysis demonstrated day 15 ALC to be an independent prognostic indicator for OS and PFS rates for both groups of patients. In conclusion, ALC is correlated with clinical outcome and requires further study.

Abstract Introduction Autologous transplantation is considered standard therapy for young and fit myeloma patients after initial therapy. Cyclophosphamide+ G-CSF is considered standard therapy for collection even though there is evidence for minimal anti-myeloma effect of cyclophosphamide, some increased short term toxicity and potential concerns regarding long term toxicity. There have been a few retrospective comparisons and one randomized study comparing cyclophosphamide based and G-CSF alone based PBSC collection. To our best knowledge they have not reported any impact in progression free survival (PFS) or overall survival (OS). We have compared here our myeloma patient cohort to explore these important endpoints. Patients and methods 89 patients (55 male and 34 female) who underwent first autologous transplant for myeloma between 2003 and 2010 were analysed in our study. Mobilization was with G-CSF alone in 45 patients (median age 58 yrs, range 38-70 yrs.) and cyclophosphamide and G-CSF in 44 (median age 58 yrs, range 41-74 yrs.). Cyclophosphamide was used at 3g/m2 and in both cases G-CSF used was lenogastrim at 10mcg/kg. There were 7 patients with ISS stage 3 in the G-CSF only group as compared to 10 in the Cyclophosphamide group. Prior chemotherapy was cyclophosphamide, thalidomide and dexamethasone in majority of cases (n=55) with no difference across both groups. Data regarding high risk genetics and pre-transplant response was unavailable. We collected data progression free survival, overall survival, harvest dose and engraftment kinetics. Data was analyzed using SPSS and log rank test. Results The median dose of stem cells collected with G-CSF alone was 3.59×106 CD34 cells/kg (range 1.84-8.09) where as with cyclophosphamide and G-CSF it was 3.8×106 CD34 cells/kg (range 1.6-13). There was no difference in engraftment between the two groups with median neutrophil engraftment (Absolute neutrophil count>0.20×109/L) at day 14 and platelet engraftment (>50×109/L) at day 15 and 16 respectively. Progression free survival was significantly better in G-CSF alone cohort (46 months vs. 38 months, P=0.016) (fig. a) Overall survival was better in the GCSF only group as well (113 months vs. 75 months, P=0.029) (fig b). In the 17 high risk patients PFS was much better in the G-CSF group (60months vs. 22 months, P=0.02) (Fig c). There were 4 (9%) admissions in the cyclophosphamide group due to neutropenic sepsis as compared to none in the G-CSF group. Discussion Cyclophosphamide and G-CSF may be associated with slightly higher stem cell yields but this margin is becoming smaller and not significant in the era of liberal plerixafor usage. In addition some patients are hospitalized due to neutropenic sepsis with this regimen. Our data shows anti-myeloma effects of cyclophosphamide +G-CSF is not demonstrated. There are ongoing studies from the Finland group which show no difference in the number of CD34+ cells collected after initial therapy with lenalidomide. The only difference is the number of days required for apheresis. In addition to above our single center experience shows both PFS and OS benefit for G-CSF only PBSC mobilization. . This may partially be explained by the slight difference in ISS risk stages in our patients but on censoring for ISS stage 3 these results were more pronounced. This is the first time we have seen any report point out towards a PFS and OS difference between two widely used mobilization regimens. This needs testing in a large randomized multi-center study to see if there is a difference and if so is this due to a change in milieu of lymphocytes. We have previously reported that absolute lymphocyte count on day 15 post autograft was reflective of a higher lymphocyte count in the apheresis bag in case of G-CSF only mobilizations as compared to cyclophosphamide +G-CSF. The absolute lymphocyte count on day 30 was a predictor for better OS. Figure 1. Progression free Survival Figure 1. Progression free Survival Figure 2. Overall survival Figure 2.
