ANC peaked at 1 and 11 days after PEG‐rhG‐CSF treatment. ANC recovery occurred on average at 5.00 (1.00, 19.00) days in the first cycle and 4.00 (1.00, 14.00) in the second cycle (Table Overall, the incidence of FN in all cycles was 29.45%. Seventy‐two (45.00%) patients had FN in the first cycle, and this number was reduced in the second cycle (19/149, 12.75%) (Table Chemotherapy delays occurred in two participants; treatment delay was due to an unrelated condition (bed shortage) in one patient, and the second case had hydrocephalus and required cerebrovascular outflow treatment and nutritional supplementation. No dose adjustment was needed.Sixty‐six(41.25%) participants received antibiotics during myelosuppression in a total of 77 cycles, accounting for 24.92% (77/309) of all cycles. The participants were administered antibiotics for a therapeutic purpose (Table
