Whether primary prophylactic pegylated-granulocyte-colony stimulating factor (PEG-G-CSF) should be administered immediately after the initiation of ramucirumab plus docetaxel (DR) to prevent the occurrence of febrile neutropenia (FN) is unclear. Our retrospective study aimed to elucidate whether PEG-G-CSF could control the occurrence of FN as a result of DR in patients with previously treated non-small-cell lung cancer. Thirty-three patients with previously treated non-small-cell lung cancer who had received DR were eligible for our analysis. Of the 33 patients, 29 received prophylactic PEG-G-CSF immediately after DR, but none developed FN. However, FN was observed in 2 (50%) of the 4 patients that were not administered PEG-CSF. The overall response and disease control rates in the 29 patients with prophylactic PEG-GSF were 31% and 62%, respectively. The median progression-free and overall survival rates of the patients with and without prophylactic PEG-GSF were 177 and 163 days (P = 0.20), and 628 and 274 days (P = 0.13), respectively. Primary prophylactic PEG-G-CSF suppressed the occurrence of FN secondary to the administration of DR.
