【摘要】 目的:討論術前血小板/淋巴細胞比值(PLR)對結直腸癌患者預后的影響。方法:選取2007年6月-2012年6月本院收治的150例結直腸癌患者作為研究對象,根據手術前、后常規血液檢查結果,計算PLR。按照PLR是否<250,將患者分為高值組(PLR≥250)28例和低值組(PLR<250)122例。觀察比較兩組患者的一般資料、不同TNM分期和不同分化程度的5年存活率,以探討PLR對結直腸癌患者預后的影響。結果:高值組結腸癌患者比例67.86%(19/28)明顯高于低值組的45.90%(56/122),接受腹腔鏡手術比例14.29%(4/28)明顯低于低值組的40.16%(49/122),低值組的5年生存率77.05%(94/122)明顯高于高值組的50.00%(14/28),且高值組晚期患者(Ⅲ、Ⅳ期)和分化差患者(差及黏液性患者)的5年生存率分別為28.57%(4/14)和40.00%(4/10),均明顯低于低值組的62.90%(39/62)和75.00%(27/36),差異均有統計學意義(P<0.05)。結論:高PLR值結直腸癌患者的5年存活率顯著低于低PLR值患者。PLR是判斷結直腸癌患者預后情況的重要指標,值得在臨床中運用。

【Abstract】 Objective:To discuss the preoperative platelet/lymphocyte ratio (PLR) impact on the prognosis of patients with colorectal cancer.Method:150 patients with colorectal cancer from June 2007 to June 2012 in our hospital were selected as research objects.According to the results of routine blood tests before surgery , calculating PLR.According to whether PLR<250,patients were divided into high-value group(PLR≥250) for 22 cases and low-value group (PLR<250) for 122 cases.The clinical general information,five-year survival rate in different TNM stages and different degrees of differentiation of two groups were observed and compared.The effect of PLR on the prognosis of patients with colorectal cancer were investigated.Result:The proportion of colon cancer in high-value group was 67.86%(19/28),it was significantly higher than 45.90%(56/122) in low-value group,the proportion of undergoing laparoscopic surgery in high-value group was 14.29%(4/28),it was significantly lower than 40.16%(49/122) in low-value group,five-year survival rate of low-value group was 77.05%(94/122),it was significantly than 50.00%(14/28) of high-value group,The five-year survival rate of advanced cancer (Ⅲ,Ⅳ stage) and differentiation of patients(patients with poor and mucinous) in high-value group were 28.57%(4/14)and 40.00%(4/10),they were significantly lower than 62.90%(39/62)and 75.00%(27/36) in low-value group,the differences were statistically significant(P<0.05).Conclusion:Five-year survival rate of high PLR value colorectal cancer patients is significantly lower than low PLR value patients.PLR is an important index to judge the prognosis of colorectal cancer patients,it is worth in clinical application..

結直腸癌是常見的腫瘤,目前的研究證實,炎癥反應和免疫狀態的變化與腫瘤的發生和進展有密切的關系[1-2]。血小板/淋巴細胞比值(PLR)是炎癥反應的主要臨床指標[3]。本院近年來通過術前分析血小板與淋巴細胞比值指導結直腸癌患者的預后,取得了較好效果,現將有關結果報告如下。
1 資料與方法
1.1 一般資料 選取2007年6月-2012年6月本院收治的150例結直腸癌患者作為研究對象,其中男102例,女48例;年齡42~77歲,平均(58.3±16.5)歲;結腸癌患者75例,直腸癌患者75例;TNM分期:Ⅰ期13例(8.67%),Ⅱ期61例(40.67%),Ⅲ期59例(39.33%),Ⅳ期17例(11.33%);手術方式:腹腔鏡下結直腸癌切除根治術53例(35.33%),開腹結直腸癌根治術97例(64.67%)。排除標準:在隨訪期因其他原因而非腫瘤死亡者;患有自身免疫性疾病或全身感染患者;隨訪期失聯者;不愿意參與本研究者。
1.2 方法
1.2.1 分組方法 在患者術前1周內及術后1周內采集靜脈血常規檢測。根據常規檢測的淋巴細胞計數和血小板計數,計算血小板/淋巴細胞比。按照術前血小板/淋巴細胞比是否<250,將患者分為高值組和低值組。其中:高值組血小板/淋巴細胞比≥250者28例;低值組血小板/淋巴細胞比<250者122例。
1.2.2 研究方法 比較高值組、低值組的臨床一般資料,統計兩組隨訪期內存活率。生存時間計算標準為:出院后到死亡或最后隨訪日。最后隨訪日為2014年5月20日。隨訪方法為:出院后第1~3年,每3個月隨訪復查一次;……
