Prospective clinical study of the efficacy and safety of different doses of PEG recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) for preventing leukopenia/neutropenia caused by concurrent chemoradiotherapy for cervical cancer

The efficacy and safety of different doses of PEG recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in the prevention of leukopenia/neutropenia during concurrent chemoradiotherapy for cervical cancer were investigated.

The patients who received concurrent radiotherapy and chemotherapy for cervical cancer from June 2020 to January 2023 were selected to evaluate the difference in efficacy, adverse reactions, and treatment cost of PEG-rhG-CSF in the prevention of leukopenia/neutropenia between the test group and the control group.

The minimum value of leukopenia/neutropenia in the test group was significantly higher than that in the control group (P < 0.05). The incidence of grade ≥ 3 leukopenia/neutropenia was significantly lower than that of the control group (P < 0.05). The number of interrupted days of radiotherapy was less than that of the control group (P < 0.05). PEG-rhG-CSF of different prophylactic doses (100 μg/kg dose or 50 μg/kg dose) had similar prophylactic effects in the test group, OR=1.192 (0.761, 1.868), P=0.443.

Prophylactic application of PEG-rhG-CSF could reduce the incidence of leukopenia/neutropenia in cervical cancer during concurrent chemoradiotherapy. There was no significant difference in efficacy and safety with prophylactic use of drug at doses of 100 μg/kg and 50 μg/kg.
