Elevated preoperative neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) predict survival rates among patients with several types of cancer. The current study sought to clarify whether NLR and PLR are clinically useful independent prognostic indicators of adenocarcinomas of the esophagogastric junction (AEG) among patients undergoing curative resections (i.e., R0 resections).
A total of 327 patients who underwent R0 resections for AEG were enrolled in the study. Data concerning demographic parameters, laboratory analyses, histopathology, and survival time were collected and analyzed.
A total of 123 patients (37.6%) had elevated preoperative NLR (≥ 5). The median follow-up duration was 24.7 months (range = 2-39 months). NLR was significantly related to histology (P = 0.035), pTNM stage (P < 0.0001) and tumor recurrence (P = 0.022). Univariate analyses revealed that NLR were significantly associated with disease-free survival (DFS) and overall survival (OS; both P < 0.0001). Multivariable analyses revealed that elevated NLR independently predicted poorer DFS (hazard ratio [HR] = 2.551, P < 0.0001) and OS (HR = 2.743, P < 0.0001). However, PLR did not significantly predict DFS or OS.
The present study indicates that elevated preoperative NLR (≥ 5) is a useful marker of tumor recurrence and independently predicts poorer disease-free and overall survival among patients with AEG undergoing R0 resections.
术前中性粒细胞与淋巴细胞比值(NLR)和血小板与淋巴细胞比值(PLR)升高可预测多种癌症患者的生存率。本研究旨在明确 NLR 和 PLR 是否是接受根治性切除术(即 R0 切除术)的食管胃结合部腺癌(AEG)患者具有临床意义的独立预后指标。
共纳入 327 例行 R0 切除术的 AEG 患者。收集并分析了患者的人口统计学参数、实验室分析、组织病理学和生存时间等数据。
共有 123 例患者(37.6%)术前 NLR 升高(≥5)。中位随访时间为 24.7 个月(范围 2-39 个月)。NLR 与组织学(P=0.035)、pTNM 分期(P<0.0001)和肿瘤复发(P=0.022)显著相关。单因素分析显示,NLR 与无病生存率(DFS)和总生存率(OS)显著相关(均 P<0.0001)。多因素分析显示,升高的 NLR 独立预测更差的 DFS(危险比 [HR]=2.551,P<0.0001)和 OS(HR=2.743,P<0.0001)。然而,PLR 并未显著预测 DFS 或 OS。
本研究表明,术前 NLR 升高(≥5)是肿瘤复发的有用标志物,可独立预测接受 R0 切除术的 AEG 患者无病生存率和总生存率更差。
