Telpegfilgrastim Injection to Reduce the Risk of Neutropenia in Patients With Solid Tumor

Summary

The objective of this real world study is to confirm the efficacy and saftey of Telpegfilgrastim injection for the prevention of chemotherapy-induced Neutropenia in Patients With Malignant solid tumor.
