摘要:

目的 探讨Ⅳ期结直肠癌化疗前血小板参数对化疗敏感性及预后的预测价值。方法 顾性分析 2010 1 月至 2021 1 月间在广州医科大学附属第二医院Ⅳ期结直肠癌化疗患者 138 例。绘制 ROC 曲线分析血小板数量(platelet,PLT)、血小板平均体积(mean platelet volume,MPV)、血小板分布宽度 Platelet distribution width,PDW)及血小板压积(plateletcrit,PCT)与结直肠癌化疗敏感性的关系,预测结直肠癌化疗敏感性的最佳临界值。建立 logistic 回归模型分析影响结直肠癌化疗敏感性的影响因素,采 用单因素及 Cox 回归模型分析血小板参数和其他临床病理因素与患者生存期及无进展生存期的关系。 结果 化疗前 PLT 与Ⅳ期结直肠癌化疗敏感性显著相关,化疗前 PLT 预测化疗敏感性的最佳临界值为 317 × 109 /L,敏感性及特异性分别为 0.620 0.818,PLT > 317 × 109 /L 化疗更敏感(P < 0.000 1),而化疗前 MPV、PDW及PCT与Ⅳ期结直肠癌化疗敏感性无相关性。Kaplan⁃Meier生存分析显示与化疗前PLT ≤ 317 × 109 /L 相比,化疗前 PLT>317 × 109 /L 的总生存期(overall survival,OS)(P = 0.143)、无进展生存期(progress free survival,PFS)(P = 0.941)差异均无统计学意义。Cox多因素分析显示化疗前PLT>317 × 109 /L 并不是影 期结直肠癌 OS PFS 的独立危险因素。结论 结直肠癌化疗前 PLT 水平与Ⅳ期结直肠癌化疗敏感 性相关,化疗前PLT 越高则化疗越敏感,但其对预后评估无明显临床价值。

Abstract:

Objective To study the predictive value of prechemotherapy platelet parameters on chemosen⁃ sitivity and prognosis of patients with Ⅳ stage colorectal cancer. Methods A retrospective analysis was conducted in 138 patients with stage Ⅳ colorectal cancer receiving chemotherapy in the Second Affiliated Hospital of Guangzhou Medical University from January 2010 to January 2021. ROC curve was used to analyze the relationship between platelet count(PLT),mean platelet volume(MPV),platelet distribution width(PDW)and plateletcrit(PCT)and chemosensitivity on colorectal cancer,and the best cut ⁃off value for predicting the chemosensitivity for colorectal cancer. A logistic regression model was established to analyze the independent related factors that affected the efficacy of chemotherapy for colorectal cancer. Univariate and Cox regression models were used to analyze the rela⁃ tionship between platelet parameters and other clinicopathological factors and patient survival and progression⁃free survival. Results Prechemotherapy PLT was significantly related to the chemosensitivity of patients with stage Ⅳ colorectal cancer. The best cut⁃off value for predicting chemosensitivity of prechemotherapy PLT was 317 × 109 /L prechemotherapy PLT > 317 × 109 /L was more sensitive to chemotherapy(P < 0.000 1),and there is no statistical correlation between MPV,PDW and PCT before chemotherapy and chemotherapy sensitivity of stage Ⅳ colorectal cancer. However,compared with prechemotherapy PLT ≤ 317 × 109 /L,prechemotherapy PLT > 317 × 109 /L showed no significant differences of OS(P = 0.143),PFS(P = 0.941)by Kaplan⁃Meier survival analysis. Cox multivariateanalysis showed prechemotherapy PLT > 317 × 109 /L was not the independent risk factor affecting OS and PFS of stage Ⅳ colorectal cancer. Conclusions The prechemotherapy PLT in colorectal cancer is correlated with the che⁃ mosensitivity in stage Ⅳ colorectal cancer,but it has no obvious clinical value in prognosis evaluation.
