【摘要】:目的:研究不同危險(xiǎn)因素對(duì)結(jié)直腸癌患者術(shù)后生存狀況的影響。方法:對(duì)2009年1月份至2010年1月份期間在河北醫(yī)科大學(xué)第四醫(yī)院接受手術(shù)治療的206例結(jié)直腸癌患者的臨床病理資料進(jìn)行回顧性分析,采用電話或信箋隨訪方式,以手術(shù)時(shí)間為起點(diǎn),至患者失訪、最后一次隨訪時(shí)間或死亡為節(jié)點(diǎn),研究的結(jié)局為死亡。然后利用Kaplan-Meier法進(jìn)行生存分析,單因素分析應(yīng)用Log-rank檢驗(yàn),采用Cox比例風(fēng)險(xiǎn)模型進(jìn)行多因素回歸分析。結(jié)果:1本研究共收集患者206例,男性126例(61.2%)女性80例(38.8%),最小年齡22歲,最大年齡84歲,中位年齡62歲。2單因素分析2.1性別、年齡(65歲、≥65歲)、腫瘤大小(5cm、≥5cm)、腫瘤位置(結(jié)腸、直腸)對(duì)術(shù)后中位存活時(shí)間、3年、5年生存率無顯著影響,P0.05。2.2術(shù)前無腸梗阻組中位存活時(shí)間、3年、5年生存率優(yōu)于有腸梗阻組,中位生存時(shí)間分別為76.63個(gè)月和50.57個(gè)月;3年存活率分別為79.0%和54.5%,5年存活率分別為71.8%和45.5%,結(jié)果顯示二者之間具有顯著統(tǒng)計(jì)學(xué)差異,P=0.021。高中分化組和低分化組中位生存時(shí)間分別為77.60個(gè)月和60.13個(gè)月,3年生存率分別為80.8%和61.8%,5年生存率分別為73.8%和52.9%,結(jié)果顯示差異具有統(tǒng)計(jì)學(xué)意義,P=0.012。無淋巴結(jié)轉(zhuǎn)移組和有淋巴結(jié)轉(zhuǎn)移組中位生存時(shí)間分別為77.83個(gè)月和63.47個(gè)月;3年生存率分別為87.0%和63.9%;5年生存率分別為82.1%和53.0%,二者間差異具有統(tǒng)計(jì)學(xué)意義,P0.001。無遠(yuǎn)處轉(zhuǎn)移組和有遠(yuǎn)處轉(zhuǎn)移組的中位生存時(shí)間分別為76.63個(gè)月和20.50個(gè)月;3年生存率分別為80.3%和23.1%;5年生存率分別為73.0%和11.5%,差異具有統(tǒng)計(jì)學(xué)意義,P=0.008。不同的T分期(T1-T4)中位生存時(shí)間分別為83.64個(gè)月、80.10個(gè)月、78.03個(gè)月、74.17個(gè)月;3年生存率分別為100%、92.6%、88.7%、69.4%;5年生存率分別為100%、88.5%、84.9%、59.5%,二者差異具有統(tǒng)計(jì)學(xué)意義,P=0.003。不同腫瘤分期(Ⅰ-Ⅳ)中位存活時(shí)間分別為79.00個(gè)月,77.67個(gè)月、65.33個(gè)月和20.50個(gè)月;3年生存率89.7%、87.9%、67.1%、23.1%;5年生存率分別86.2%、81.3%、56.2%、11.5%,差異具有統(tǒng)計(jì)學(xué)意義,P0.001。3多因素COX回歸分析術(shù)前有腸梗阻(P=0.038)、腫瘤分期(P=0.016)、腫瘤分化程度(P=0.003)、T分期(P=0.016)、M分期(P=0.025)是影響結(jié)直腸癌患者術(shù)后生存狀況的獨(dú)立危險(xiǎn)因素。結(jié)論:1術(shù)前有無腸梗阻、腫瘤分期、腫瘤分化程度、T分期、有無淋巴轉(zhuǎn)移、M分期對(duì)術(shù)后生存率有顯著影響。2術(shù)前有無腸梗阻、腫瘤分期、腫瘤分化程度、T分期、M分期為影響結(jié)直腸癌患者術(shù)后生存的獨(dú)立危險(xiǎn)因素。
[Abstract]:Objective: to study the influence of different risk factors on postoperative survival of colorectal cancer patients. Methods: the clinical and pathological data of 206 patients with colorectal cancer who underwent surgical treatment in the fourth Hospital of Hebei Medical University from January 2009 to January 2010 were retrospectively analyzed, and followed up by telephone or letterhead. The outcome of the study was death, starting with the operative time, the last follow-up time or death as the node. Then Kaplan-Meier method is used to analyze survival, single factor analysis is applied to Log-rank test, and Cox proportional risk model is used to carry out multivariate regression analysis. Results: 1 A total of 206 patients were collected in this study, 126 males (61.2%), 80 females (38.8%), the minimum age was 22 years old, the maximum age was 84 years old, the median age was 62 years old. Tumor size (5 cm, 鈮,
