In cancer patients, the balance between neutrophil (N) and lymphocyte (L) cell counts fluctuates with advancing disease. The objective of our study was to determine the prognostic implications of the N/L ratio in the peripheral blood of rectal cancer patients.
Study participants were identified from a prospective cohort of patients with rectal cancer in Dalian of China (n = 123).
The median baseline N/L ratio was 2.41 +/- 2.206 (range, 0.76-20.45). Our results revealed that the N/L ratio was significantly associated with tumor size (P = 0.003) and level of cancer antigen 125 (P = 0.027). A multivariate Cox model established a significant relationship between the N/L ratio and survival (adjusted hazard ratio, 2.615; 95% confidence interval, 1.152-5.933; P = 0.021).
These results suggest that the N/L ratio is an independent prognostic factor in rectal cancer, and the N/L ratio may serve as a clinically accessible and useful biomarker for patient survival.
在癌症患者中，中性粒细胞（N）与淋巴细胞（L）计数之间的平衡会随着疾病进展而波动。我们研究的目的是确定直肠癌患者外周血中N/L比值的预后意义。
研究参与者来自中国大连的直肠癌患者前瞻性队列（n = 123）。
基线N/L比值的中位数为2.41±2.206（范围为0.76 - 20.45）。我们的结果显示，N/L比值与肿瘤大小（P = 0.003）和癌抗原125水平（P = 0.027）显著相关。多变量Cox模型确定了N/L比值与生存率之间的显著关系（调整后的风险比为2.615；95%置信区间为1.152 - 5.933；P = 0.021）。
这些结果表明，N/L比值是直肠癌的一个独立预后因素，并且N/L比值可能作为一种临床上可获取且有用的患者生存生物标志物。
