[A clinical study of rhG-CSF in accelerating hematological recovery following autologous hematopoietic stem cells transplantation].

BACKGROUND & OBJECTIVE: High dose chemotherapy and radiotherapy supported by autologous hematopoietic stem cells transplantation(AHSCT) can improve the efficacy of some malignant solid tumors. Successful AHSCT should owe to rational usage of recombinant human granulocyte colony-stimulating factor (rhG-CSF) in some extent. The purpose of this study was to observe the role of rhG-CSF in hematological recovery after AHSCT for patients with solid tumors.

METHODS

A total of 130 patients with solid tumors were divided into two groups. The rhG-CSF group received rhG-CSF at the dose of 250-300 microg daily from day 6 until WBC recovering to 5.0 x 10(9)/L. The control group did not receive rhG-CSF after AHSCT.

RESULTS

A total of 132 person-times AHSCT were finished and 2 patients of them experienced twice transplantation. Twenty-four patients received autologous bone marrow transplantation (ABMT), 12 of them received rhG-CSF following AHSCT and the others did not. One hundred and six persons underwent autologous peripheral blood stem cells transplantation (APBSCT), 47 patients received rhG-CSF and 61 did not. (1)In rhG-CSF group and control group of ABMT,the median days of WBC up to 5.0 x 10(9)/L were 14 days and 24 days (P< 0.001),respectively. The median time of hospitalization was 33 days and 41 days (P< 0.05),respectively. There was no statistical difference in median time of PLT recovering to 20 x 10(9)/L and 50 x 10(9)/L in the two groups.(2)In rhG-CSF group and control group of APBSCT,the median time of WBC recovering to 5.0 x 10(9)/L were 10 days and 13 days (P< 0.01), respectively. The median time of hospitalization was 17 days and 20 days(P< 0.01),respectively. There was no significantly statistical difference in median time of PLT recovering to 50 x 10(9)/L in the two groups. (3)The frequency of infectious complication was no statistical difference between two groups (P=0.45).

CONCLUSION

rhG-CSF administration after AHSCT can obviously accelerate the recovery of WBC and shorten the time of hospitalization, but there is no significant effect on the recovery of PLT. Further study is needed to investigate whether rhG-CSF can reduce the infectious complication.
