Clinical Trial Summary

The purpose of this study is to try to find a better injection regimen (including time and dose) of PEG-rhG-CSF, which is supposed to better prevent bone marrow suppression and/or FN in breast cancer patients who receive chemotherapy.

Intervention

Drug:
• Day 7 regimen
patients received a single dose of 6mg of PEG-rhG-CSF(pegfilgrastim), as a single subcutaneous injection on day 7 after chemotherapy. If FN occurs in the experimental group and the control group, reduce the dose of chemotherapy in the next course of treatment, timely change the chemotherapy regimen, and closely monitor to ensure patient safety. Record the results of routine blood follow-up and temperature curves of patients at different time periods. If WBC >= 15 x 10^9/L in the first chemotherapy cycle, then 3mg PEG-rhG-CSF will be used in the second chemotherapy cycle.
• Day 3 regimen
patients received a single dose of 6mg of PEG-rhG-CSF(pegfilgrastim), as a single subcutaneous injection on day 3 after chemotherapy. If FN occurs in the experimental group and the control group, reduce the dose of chemotherapy in the next course of treatment, timely change the chemotherapy regimen, and closely monitor to ensure patient safety. Record the results of routine blood follow-up and temperature curves of patients at different time periods. If WBC >= 15 x 10^9/L in the first chemotherapy cycle, then 3mg PEG-rhG-CSF will be used in the second chemotherapy cycle.
