Preoperative neutrophil-to-lymphocyte ratio (NLR) has been identified as a predictor for the recurrence of hepatocellular carcinoma (HCC), but the cut-off of NLR is inconsistent in various studies. Thus, we detected the prognostic value of preoperative NLR in the single-nodule small HCC (SHCC) patients using X-tile for cutpoint.
Between January 2007 and December 2010, a total of 222 single-nodule SHCC patients underwent curative resection and were examined for the prognostic roles of preoperative NLR by X-tile.
In this study, all patients were divided into the low-NLR subgroup (NLR ≤ 2.1) and the high-NLR subgroup (NLR > 2.1) by X-tile. Preoperative NLR showed predictive value for time to recurrence (TTR) and overall survival (OS). Moreover, NLR was associated with total bilirubin, white blood cell counts, and HBsAg, respectively (P = 0.012, <0.001, and 0.011, respectively). Especially, NLR could discriminate the outcome of patients in the subgroup with alpha-fetoprotein (AFP) levels of ≤400 ng/mL. Importantly, postoperative transcatheter arterial chemoembolization (TACE) had close relationship with OS (P = 0.001) and TTR (P ≤ 0.001).
Therefore, this study indicates that preoperative NLR, divided by X-tile for the cutpoint, is a simple prognostic marker for the patients with single-nodule SHCC after curative resection.
术前中性粒细胞与淋巴细胞比值(NLR)已被确定为肝细胞癌(HCC)复发的预测指标,但在各项研究中NLR的临界值并不一致。因此,我们使用X-tile软件确定切点,检测术前NLR在单结节小肝癌(SHCC)患者中的预后价值。
2007年1月至2010年12月期间,共有222例单结节SHCC患者接受了根治性切除术,并通过X-tile软件检测术前NLR的预后作用。
在本研究中,所有患者通过X-tile软件被分为低NLR亚组(NLR≤2.1)和高NLR亚组(NLR>2.1)。术前NLR对复发时间(TTR)和总生存期(OS)具有预测价值。此外,NLR分别与总胆红素、白细胞计数和乙肝表面抗原相关(P值分别为0.012、<0.001和0.011)。特别是,NLR可以区分甲胎蛋白(AFP)水平≤400 ng/mL亚组患者的预后。重要的是,术后经动脉化疗栓塞术(TACE)与OS(P = 0.001)和TTR(P≤0.001)密切相关。
因此,本研究表明,通过X-tile软件确定切点的术前NLR是单结节SHCC患者根治性切除术后的一个简单预后标志物。
