Real-world Study on the Prevention of Neutropenia After Tumor Treatment With Mecapegfilgrastim Injection

Summary

This study is a multicenter, observational real-world study, aiming to observe and evaluate the efficacy and safety of prophylactic application of Mecapegfilgrastim Injection in tumor patients after radiotherapy/chemotherapy/immunotherapy in the real world to prevent neutropenia.The subjects who met the inclusion criteria of the protocol were defined as those who needed radiotherapy/chemotherapy/immunotherapy after being diagnosed with solid malignant tumors. The researchers believed that the subjects needed to use Mecapegfilgrastim Injection for primary/secondary prevention after receiving tumor treatment.

  2. Patients who are currently receiving treatment regimens for moderate FN risk and meet any one of the factors that increase the risk coefficient;
  3. FN or dose-limiting neutropenia events have occurred in previous treatment cycles;
  4. In addition to the above, the researchers believe that the medication regimens will cause neutropenia and affect the normal treatment of the subjects; 4. Researchers believe that they can benefit; 5. Voluntarily participate in this clinical trial and be able to sign the informed consent form in person.
