Summary

This is a prospective observational study designed to observe and evaluate the safety and efficacy of mecapegfilgrastim in the treatment of moderate-to-severe myelosuppression associated with concurrent chemoradiotherapy. The project will provide more robust evidence-based medical support for the use of long-acting granulocyte-stimulating agents in patients undergoing concurrent chemoradiotherapy.

Conditions

  • Myelosuppression
  • Thoracic Neoplasms
  • Chemoradiotherapy

Interventions

DRUG

Mecapegfilgrastim injection

After enrollment, a single subcutaneous dose of mecapegfilgrastim should be administered 24 hours following completion of each chemotherapy cycle. The recommended dose is a fixed 6 mg, or an individualized 100 μg/kg based on the patient's body weight. If neutrophil counts remain below 0.5 × 10⁹/L for more than 24 hours after mecapegfilgrastim administration, short-acting G-CSF may be used as rescue therapy at the investigator's discretion until neutrophil levels return to normal.

DRUG

Oral or short-acting granulocyte-stimulating agents

In the first cycle after enrollment, patients will be followed for changes in neutrophil counts. Should the neutrophil level fall below 1.5 × 10⁹/L, the investigator may, based on clinical judgment, decide whether to intervene with leucogen tablets or other granulocyte-boosting agents. If the count remains below 1.0 × 10⁹/L, short-acting G-CSF may be administered as a rescue therapy.
