Background/Aim: The efficacy of aflibercept plus 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) therapy has been demonstrated in patients with metastatic colorectal cancer (mCRC) in global and Japanese clinical trials. However, a practical biomarker to predict its efficacy is lacking. Patients and Methods: This was a single-institution retrospective study of 21 patients with mCRC consecutively treated with aflibercept plus FOLFIRI from March 2018 to July 2019. We investigated the association and predictive value of pretreatment blood inflammation and immune-based scores, including the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio, using their median values as cut-offs, in regard to disease control (DC), progression-free (PFS), and overall (OS) survival. Results: The number of patients in each treatment line of aflibercept was as follows: Second, 14 (66.7%); third, four (19.0%); fourth, two (9.5%); eighth, one (4.8%). The median number of aflibercept treatment courses was seven (range=2-17). The median follow-up time was 391 days. In univariate analysis, patients with DC had a significantly lower PLR than those without DC. Only the PLR was significantly negatively associated with PFS, but not with OS. Multivariate analysis showed a significantly poor prognostic impact of a high PLR on PFS (hazard ratio=10.28; p=0.003). Conclusion: A low pretreatment PLR might be a predictor of aflibercept efficacy in patients with mCRC and may be clinically useful for selecting patient responders.

血小板与淋巴细胞比率对接受阿柏西普治疗的转移性结直肠癌患者的预后作用

背景/目的:阿柏西普加 5-氟尿嘧啶、亚叶酸和伊立替康 (FOLFIRI) 疗法的疗效已在全球和日本的临床试验中证明在转移性结直肠癌 (mCRC) 患者中。然而,缺乏一种实用的生物标志物来预测其功效。患者和方法:这是一项单机构回顾性研究,对 21 名 mCRC 患者从 2018 年 3 月至 2019 年 7 月连续接受阿柏西普联合 FOLFIRI 治疗。我们调查了治疗前血液炎症和免疫评分的关联和预测价值,包括中性粒细胞- 淋巴细胞比率、血小板与淋巴细胞比率 (PLR) 和淋巴细胞与单核细胞比率,使用它们的中值作为临界值,在疾病控制 (DC)、无进展 (PFS) 和总体 ( OS) 生存。结果:阿柏西普各治疗线的患者人数如下: 第二,14(66.7%);第三、四个(19.0%);四、二(9.5%);第八,一个(4.8%)。阿柏西普治疗疗程的中位数为 7 个(范围 = 2-17)。中位随访时间为 391 天。在单变量分析中,DC 患者的 PLR 显着低于没有 DC 的患者。只有 PLR 与 PFS 显着负相关,而与 OS 无关。多变量分析显示高 PLR 对 PFS 的预后影响显着较差(风险比 = 10.28;p = 0.003)。结论:低治疗前 PLR 可能是阿柏西普在 mCRC 患者中疗效的预测因素,并且可能在临床上对选择患者反应者有用。阿柏西普治疗疗程的中位数为 7 个(范围 = 2-17)。中位随访时间为 391 天。在单变量分析中,DC 患者的 PLR 显着低于没有 DC 的患者。只有 PLR 与 PFS 显着负相关,而与 OS 无关。多变量分析显示高 PLR 对 PFS 的预后影响显着较差(风险比 = 10.28;p = 0.003)。结论:低治疗前 PLR 可能是阿柏西普在 mCRC 患者中疗效的预测因素,并且可能在临床上对选择患者反应者有用。阿柏西普治疗疗程的中位数为 7 个(范围 = 2-17)。中位随访时间为 391 天。在单变量分析中,DC 患者的 PLR 显着低于没有 DC 的患者。只有 PLR 与 PFS 显着负相关,而与 OS 无关。多变量分析显示高 PLR 对 PFS 的预后影响显着较差(风险比 = 10.28;p = 0.003)。结论:低治疗前 PLR 可能是阿柏西普在 mCRC 患者中疗效的预测因素,并且可能在临床上对选择患者反应者有用。但不是操作系统。多变量分析显示高 PLR 对 PFS 的预后影响显着较差(风险比 = 10.28;p = 0.003)。结论:低治疗前 PLR 可能是阿柏西普在 mCRC 患者中疗效的预测因素,并且可能在临床上对选择患者反应者有用。但不是操作系统。多变量分析显示高 PLR 对 PFS 的预后影响显着较差(风险比 = 10.28;p = 0.003)。结论:低治疗前 PLR 可能是阿柏西普在 mCRC 患者中疗效的预测因素,并且可能在临床上对选择患者反应者有用。
