    [Abstract] Objective To evaluate affects about perioperative allogenenic blood transfusion (ABT) on the prognosis of patients with gastric cancer surgery. Methods PubMed, Cochrane Library, EMBASE, and Highwire biomedical databases were retrieved by computer, and clinical controlled trials from January 2000 to January 2019 to study the effect of perioperative ABT on the prognosis of patients with gastric cancer surgery were collected. A meta-analysis was performed using Stata version 12.0 software to systematically evaluate the effects of perioperative ABT on 5-year survival, tumor recurrence, and postoperative complications. Results A total of 20 high-quality related literatures were included. Compared with the non-transfusion group, the 5-year survival rate of patients in the ABT group was reduced (OR = 0.47, 95%CI: 0.39-0.56, P = 0.005), while the tumor recurrence rates (OR = 2.09, 95%CI: 1.35-3.25, P = 0.000) and the incidence of postoperative complications were increased (OR = 2.40, 95%CI: 1.81-3.19, P = 0.000), and the differences were statistically significant. Conclusion Perioperative ABT can adversely affect the prognosis of patients with gastric cancer surgery.

    胃腸腫瘤是一項重要的世界健康問題,其中胃癌是世界上常見的惡性腫瘤之一[1-2],執(zhí)行腫瘤根治手術(shù)是該疾病患者的首選治療方法[3]。目前,越來越多的證據(jù)顯示,圍術(shù)期進行外源性輸血(ABT)對腫瘤患者預(yù)后產(chǎn)生負面影響[4],但針對這一問題仍有很大爭議[5-6]。因此,本研究針對圍術(shù)期ABT對胃癌手術(shù)患者預(yù)后影響這一問題進行了新的系統(tǒng)性回顧和meta分析,更加全面地評估和更新相關(guān)參考文獻,以期為臨床研究提供理論依據(jù)。

    1 資料與方法

    1.1 資料檢索

    查閱2000年1月~2019年1月關(guān)于圍術(shù)期ABT與胃癌手術(shù)患者預(yù)后關(guān)系的文獻。具體檢索方法:計算機檢索PubMed、Cochrane Library、EMBASE、Highwire生物醫(yī)學(xué)數(shù)據(jù)庫。英文檢索詞包括:Perioperative,Allogenenic Blood Transfusion,Clinical Outcome,Gastric Carcinoma,Gastric Cancer,Stomach Cancer,Carcinoma of Stomach。

    1.2 納入及排除標準

    文獻納入標準:①研究對象。評價ABT與胃癌手術(shù)患者預(yù)后之間的關(guān)系;②ABT組與非輸血組比較的臨床對照試驗;③如果數(shù)據(jù)在同一時期或同一科研團隊進行了多次報告與更新,則僅選擇最新一次研究或數(shù)據(jù)樣本最大。排除標準:①自體輸血者或未進行手術(shù);②提供信息不完整;③質(zhì)量較低。

    1.3 觀察指標

    主要觀察指標:5年生存率、腫瘤復(fù)發(fā)率和術(shù)后并發(fā)癥發(fā)生率。針對各個研究收集第一作者姓氏、出版年份及國家等信息。

    1.4 質(zhì)量評估

    根據(jù)紐卡斯爾-渥太華量表(NOS)評估納入研究的質(zhì)量,NOS評分≥7分研究被定義為高質(zhì)量研究,最高分為9分[7]。本研究僅納入高質(zhì)量研究。

    1.5 統(tǒng)計學(xué)方法

    本研究用Stata 12.0軟件對所得數(shù)據(jù)進行meta分析。計數(shù)資料采用Mantele-Haenszel法合并OR值及95%CI,采用Egger法檢測發(fā)表偏倚情況。先對納入研究進行臨床異質(zhì)性檢驗,若各研究之間無異質(zhì)性(I2 < 50%,P < 0.05),選擇固定效應(yīng)模型,否則選擇隨機效應(yīng)模型。通過敏感性分析,進一步探究文章異質(zhì)性。以P < 0.05為差異有統(tǒng)計學(xué)意義。

    2 結(jié)果

    2.1 文獻檢索結(jié)果

    根據(jù)檢索策略進行初步檢索,共獲得文獻1050篇。通過篩選,本研究最終納入20篇[8-27]高質(zhì)量相關(guān)文獻。檢索流程見圖1。各研究基本特征見表1。

    2.2 Meta分析結(jié)果

    與非輸血組比較,ABT可顯著降低胃癌手術(shù)患者5年生存率(OR = 0.47,95%CI:0.39~0.56),提高腫瘤復(fù)發(fā)率(OR = 2.09,95%CI:1.35~3.25)及術(shù)后并發(fā)癥發(fā)生率(OR = 2.40,95%CI:1.81~3.19),差異均有統(tǒng)計學(xué)意義(均P < 0.05)。見圖2~4。

    2.3 發(fā)表偏倚

    以本研究3項觀察指標繪制漏斗圖,見圖5。漏斗圖分布趨勢不明顯,但分布對稱,提示存在一定程度發(fā)表偏倚。見表2。

    2.4 敏感性分析

    通過分別剔除每一項研究進行敏感性分析,發(fā)現(xiàn)結(jié)果與刪除前一致,提示本評價結(jié)果穩(wěn)定。

    3 討論

    Meta分析結(jié)果顯示,在接受過根治性手術(shù)的胃癌患者中,圍術(shù)期ABT與預(yù)后不良顯著相關(guān),包括5年生存率降低,腫瘤復(fù)發(fā)率和術(shù)后并發(fā)癥發(fā)生率升高。但meta分析仍然存在一些局限性。這些試驗中未提及麻醉和鎮(zhèn)痛的方法及藥物,可能在某種程度上有所不同。雖然經(jīng)Egger法檢測各研究的發(fā)表偏倚情況不明顯,但依舊存在一定程度的發(fā)表偏倚情況。因此關(guān)于圍術(shù)期ABT對胃癌手術(shù)患者預(yù)后影響的研究,還需要更多臨床試驗作為依據(jù),綜合分析。

    在對外科患者的第1次前瞻性分析中報道,對紅細胞進行更為謹慎地處理、調(diào)整以及嚴格把控輸血觸發(fā)因素,不會增加發(fā)病率和死亡率。Dixon等[28]將紅細胞輸血率命名為腫瘤手術(shù)中被忽視的潛在質(zhì)量參數(shù)。因此,研究ABT對胃癌手術(shù)患者預(yù)后的影響非常重要。
