Abstract
- Objective To explore the safety and efficacy of pegylated recombinant human granulocyte colony⁃stimulating factor (PEG⁃rhG⁃CSF) in preventing chemotherapy⁃induced neutropenia in patients with breast cancer and non⁃small cell lung cancer (NSCLC), and to provide the basis for clinical application. Methods According to the principle of open⁃label, randomized, parallel⁃group controlled clinical trial, all patients were randomized by 1 ∶ 1 ∶ 1 into three groups to receive PEG⁃rhG⁃CSF 100 μg/ kg, PEG⁃rhG⁃CSF 6 mg, or rhG⁃CSF 5 μg/ kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1⁃2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+epirubicin+cyclophosphamide) or TA ( docetaxel + epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle. Results The duration of grade 3⁃4 neutropenia in the PEG⁃rhG⁃CSF 100 μg/ kg and PEG⁃rhG⁃CSF 6 mg groups were similar with that in the rhG⁃CSF 5 μg/ kg group (P>0.05 for all). The incidence rate of grade 3⁃4 neutropenia in the PEG⁃rhG⁃CSF 100 μg/ kg group, PEG⁃rhG⁃CSF 6 mg group, and G⁃CSF 5 μg/ kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non⁃significant difference among the three groups (P = 0.963). The incidence rate of febrile neutropenia in the PEG⁃rhG⁃CSF 100 μg/ kg group, PEG⁃rhG⁃CSF 6 mg group and G⁃CSF 5 μg/ kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P =0.935). The incidence rate of adverse events in the PEG⁃rhG⁃CSF 100 μg/ kg group, PEG⁃rhG⁃CSF 6 mg group and G⁃CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non⁃significant difference among them (P =0.581). Conclusions In patients with breast cancer and non⁃small cell lung cancer (NSCLC) undergoing TAC/ TA chemotherapy, a single 100 μg/ kg injection or a single fixed 6 mg dose of PEG⁃rhG⁃CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG⁃CSF 5 μg/ kg/ d, a single 100 μg/ kg injection or a single fixed 6 mg dose of PEG⁃rhG⁃CSF has similar effect and is more advantageous in preventing chemotherapy⁃induced neutropenia.
