【摘要】:目的 氧化應(yīng)激損傷在腫瘤的發(fā)生及發(fā)展中起著促進(jìn)作用已被學(xué)術(shù)界認(rèn)可,關(guān)于胃癌的研究也發(fā)現(xiàn)胃癌患者腫瘤組織及血漿氧化應(yīng)激產(chǎn)物濃度較對照組存在明顯差異。本研究通過檢測分析不同臨床分期胃癌患者腫瘤組織及非瘤胃組織氧化應(yīng)激相關(guān)指標(biāo)的差異,揭示氧化應(yīng)激損傷與胃癌進(jìn)展的關(guān)系,,為未來胃癌檢測分期及腫瘤抗氧化治療提供理論及臨床依據(jù)。 方法 選擇2012年7月-2014年3月我院的收治并行胃癌根治術(shù)的胃癌患者60例。病例均為術(shù)前胃鏡活檢確診為胃癌,影像學(xué)未發(fā)現(xiàn)遠(yuǎn)處轉(zhuǎn)移表現(xiàn),無術(shù)前輔助化療史和抗癌藥物等抗氧化藥物治療史,手術(shù)指征明確且排除手術(shù)禁忌、術(shù)后病理證實(shí)為I-III期的胃腺癌患者。并根據(jù)其術(shù)后病理分期,分別分成I期組、II期組、III期組。取術(shù)后標(biāo)本腫瘤中心及非瘤胃組織,檢測其丙二醛(malonaldehyde,MDA)濃度和超氧化物歧化酶(superoxide dismutase,SOD)活性,分析并比較數(shù)據(jù)間差異。 結(jié)果: 1.本次研究共入組病例60例。其中I期組12例(男性8例,女性4例);年齡(58.1土10.7)歲;手術(shù)方式腹腔鏡5例,開放7例;手術(shù)切除范圍10例行胃全切,2例行遠(yuǎn)端胃切除。II期組共20例(男13例,女性7例);年齡(63.1土8.3)歲;手術(shù)方式腹腔鏡9例,開放11例;手術(shù)切除范圍16例行胃全切,4例行遠(yuǎn)端胃切除。III期組28例(男性19例,女性9例);年齡(64.8土8.8)歲;手術(shù)方式腹腔鏡13例,開放15例;手術(shù)切除范圍全胃23例,5例行遠(yuǎn)端胃切除。三組病例間除I期組年齡分布與II、III期組間有顯著差異(P0.05)外,組間年齡分布、男女性別比例、手術(shù)方式、手術(shù)切除術(shù)范圍均無顯著性差異。 2. I期組麻醉時(shí)間(麻醉誘導(dǎo)開始至麻醉拔管時(shí)間)(253.2土48.3min),腫瘤血供阻斷時(shí)間(離斷胃網(wǎng)膜右血管至腫瘤整體切除時(shí)間)(68.1土15.4min),術(shù)中出血量(98土36.4ml);II期組麻醉時(shí)間(267.2土53.1min),腫瘤血供阻斷時(shí)間(72.3土25.2min),術(shù)中出血量(103.5土42.1ml);III期組麻醉時(shí)間(271.2土44.2min),腫瘤血供阻斷時(shí)間(69.4土29.1min),術(shù)中出血量(123.1土58.1ml).三組間術(shù)中資料對比,麻醉時(shí)間、腫瘤血管阻斷時(shí)間、術(shù)中出血量均無顯著性差異(P0.05)。 3.三組各組內(nèi)對比:MDA濃度三組間腫瘤中心組織與非瘤胃組織對比,前者濃度更高,組內(nèi)對比差異均有統(tǒng)計(jì)學(xué)意義(P0.05);SOD活性腫瘤中心組織與非瘤胃組織對比,前者水平較低,組內(nèi)對比差異有統(tǒng)計(jì)學(xué)意義(P0.05)。 4.三組間對比:腫瘤組織及非瘤胃組織中MDA濃度對比,I期組較II、III期組濃度明顯偏低,差異有統(tǒng)計(jì)學(xué)意義(P0.05);II期組較III期組濃度偏低,差異有統(tǒng)計(jì)學(xué)意義(P0.05);三組間MDA水平呈逐漸升高趨勢。腫瘤組織SOD活性對比,I期組較II、III期組水平明顯偏低,差異有統(tǒng)計(jì)學(xué)意義(P0.05);II期組與III期組間差異不明顯(P0.05)。非瘤胃組織SOD活性對比,I期組較II、III期組水平偏低,差異有統(tǒng)計(jì)學(xué)意義(P0.05);II期組較III期組間水平偏低亦(P0.05);三組間SOD濃度呈升高趨勢。 結(jié)論 1、不同時(shí)期胃癌患者其腫瘤組織氧化應(yīng)激損傷較癌旁非瘤胃組織均有加重表現(xiàn)。 2、隨著腫瘤進(jìn)展,腫瘤組織及瘤旁非瘤組織其氧化應(yīng)激損傷總體呈逐漸加重趨勢。 3、腫瘤組織其抗氧化損傷活性逐漸加強(qiáng),但其最高活性存在限制。
[Abstract]:objective
Oxidative stress in the occurrence and development of tumor plays an important role in the academic circles has been recognized, studies on gastric cancer also found that oxidative stress concentration of gastric cancer tissue and plasma compared with the control group, there are obvious differences. In this study, through the analysis of the difference of corresponding indexes of oxidative stress in different clinical stages of gastric cancer tissues and non rumen tissue the relationship between oxidative stress and the progression of gastric cancer, and provide theoretical and clinical basis for future detection of gastric cancer staging and tumor antioxidant treatment.
Method
In July 2012 -2014 year in March in our hospital were parallel 60 gastric cancer patients with radical resection of gastric cancer cases. The cases were diagnosed as gastric cancer by preoperative biopsy and imaging without distant metastasis, no preoperative adjuvant chemotherapy drug treatment history and history of anti cancer drugs, surgical indications and contraindication clear exclusion, postoperative pathologic stage I-III gastric cancer patients. According to the postoperative pathological staging, were divided into I group, II group, III group and non tumor specimens. The center of rumen tissue after operation, the detection of malondialdehyde (malonaldehyde, MDA) concentration and superoxide dismutase (superoxide dismutase, SOD) the difference between activity data and analysis.
