BACKGROUND: Recombinant human granulocyte colony-stimulating factor (rhG-CSF) reduces neutropenia events and is widely used in cancer patients receiving chemotherapy. However, the effects of rhG-CSF on distant organ metastasis (DOM) in non-small-cell lung cancer (NSCLC) patients following postoperative chemotherapy are not clear.
METHODS: A retrospective cohort study was performed on NSCLC patients who underwent complete surgical resection and postoperative systemic chemotherapy at The First Affiliated Hospital of Nanchang University between 1 January 2012 and 31 December 2017. The effect of rhG-CSF on DOM was assessed with other confounding factors using Cox regression analyses.
RESULTS: We identified 307 NSCLC patients who received postoperative systemic chemotherapy (n = 246 in the rhG-CSF group, n = 61 in the No rhG-CSF group). The incidence of DOM in postoperative NSCLC patients with rhG-CSF treatment was observably higher than in patients without rhG-CSF treatment (48.3% vs. 27.9%, p < 0.05). Univariate regression analysis revealed that rhG-CSF and pathological stage were independent risk factors for metastasis-free survival (MFS) (p < 0.05). RhG-CSF users had a higher risk of DOM (adjusted HR: 2.33, 95% CI: 1.31-4.15) than nonusers of rhG-CSF. The association between rhG-CSF and the risk of DOM was significant only in patients presenting with myelosuppression (HR: 3.34, 95% CI: 1.86-6.02) and not in patients without myelosuppression (HR: 0.71, 95% CI: 0.17-2.94, Interaction p-value< 0.01). The risk increased with higher dose density of rhG-CSF compared to rhG-CSF versus no users (p for trend< 0.001).
CONCLUSION: These analyses indicate that rhG-CSF use is related to DOM following postoperative chemotherapy in NSCLC.
