The purpose of this study was to analyze the predictive value of neutrophil/lymphocyte ratio (NLR) to better clarify which patient groups will benefit the most from particular treatments like bevacizumab.
A total of 245 treatment-naive metastatic colorectal cancern (mCRC) patients were retrospectively enrolled and divided into 2 groups: 145 group A patients were treated with chemotherapy in combination with bevacizumab, and 100 group B patients were treated as above without bevacizumab.
Group A patients had better median overall survival (OS) and progression-free survival (PFS) (24.0 and 9.0 months) than group B patients (20 and 6.0 months) (p=0.033; p=0.015). In patients with low NLR, OS and PFS were significantly longer in group A patients (27 vs 18 months, p=0.001; 11 vs 7 months, p=0.017).
We conclude that NLR, a basal cancer related inflammation marker, is associated with the resistance to bevacizumab- based treatments in mCRC patients.
本研究旨在分析中性粒细胞/淋巴细胞比值（NLR）的预测价值，以更好地阐明哪些患者群体将从贝伐单抗等特定治疗中获益最大。
共回顾性纳入245例未经治疗的转移性结直肠癌（mCRC）患者，并分为两组：145例A组患者接受化疗联合贝伐单抗治疗，100例B组患者接受上述不含贝伐单抗的治疗。
A组患者的中位总生存期（OS）和无进展生存期（PFS）（分别为24.0个月和9.0个月）优于B组患者（分别为20个月和6.0个月）（p = 0.033；p = 0.015）。在NLR较低的患者中，A组患者的OS和PFS显著更长（27个月对18个月，p = 0.001；11个月对7个月，p = 0.017）。
我们得出结论，NLR作为一种基础癌症相关炎症标志物，与mCRC患者对基于贝伐单抗治疗的耐药性相关。
