ABSTRACT
Objective:
The effect and safety of etoposide combined with G-CSF were compared with those of cyclophosphamide combined with G-CSF in autologous peripheral blood mobilization in patients with multiple myeloma (MM) .Methods:
Patients with MM who received autologous peripheral blood stem cell mobilization and collection in the Department of Hematology, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 1, 2020 to July 31, 2023 were included. A total of 134 patients were screened by propensity score matching technology according to a 1â¶1 ratio. A total of 67 cases were each treated with ETO combined with G-CSF mobilization scheme (ETO group) and CTX combined with G-CSF mobilization scheme (CTX group). Their clinical data were retrospectively analyzed.Results:
â Collectionresults:
the ETO and CTX groups [2 (1-3) d vs 2 (1-5) d; P<0.001] and CD34(+) cells [7.62×10(6) (2.26×10(6)-37.20×10(6)) /kg vs 2.73×10(6) (0.53×10(6)-9.85×10(6)) /kg; P<0.001] were collected. The success rate of collection was 100.0% (67/67) versus 76.1% (51/67) (P<0.001). Excellent rate of collection was 82.1% (55/67) versus 20.9% (14/67; P<0.001). Two patients in the ETO group switched protocols after 1 day of collection, and 11 patients in the CTX group switched protocols after 1-2 days of collection. â¡Adverse reactions granular deficiency with fever (21.5%[14/65] vs. 10.7%[6/56]; P=0.110), requiring platelet transfusion [10.7% (7/65) vs 1.8% (1/56) ; P=0.047]. â¢Until the end of follow-up, 63 cases in the ETO group and 54 cases in the CTX group have undergone autologous transplantation. The median number of CD34(+) cells infused in the two groups was 4.62×10(6) (2.14×10(6)-19.89×10(6)) /kg versus 2.62×10(6) (1.12×10(6)-5.31×10(6)) /kg (P<0.001), neutrophil implantation time was 11 (9-14) d versus 11 (10-14) d (P=0.049), and platelet implantation time was 11 (0-19) d vs. 12 (0-34) d (P=0.035). One case in the CTX group experienced delayed platelet implantation.Conclusion:
The mobilization scheme of etoposide combined with G-CSF requires relatively platelet transfusion, but the collection days are shortened. The collection success rate, excellent rate, and the number of CD34(+) cells obtained are high, and the neutrophil and platelet engraftment is accelerated after transplantation.Key words
