【摘要】:背景與目的:腎細(xì)胞癌是常見泌尿系統(tǒng)腫瘤,早期腎癌以手術(shù)治療為主,但術(shù)后復(fù)發(fā)率仍然較高,對(duì)放療、化療不敏感,如何減少術(shù)后的復(fù)發(fā)和轉(zhuǎn)移是臨床研究的重要方向,由于腎癌具有較強(qiáng)的免疫源性,負(fù)載腫瘤抗原的DC疫苗成為腎癌治療的有效手段,本研究對(duì)42例采用抗原致敏DC聯(lián)合CIK治療的腎癌術(shù)后患者進(jìn)行了回顧性分析,觀察其對(duì)腎癌術(shù)后患者免疫功能的影響。 方法:選取2012年3月至2014年04月蘇州大學(xué)附屬第二醫(yī)院收治的42例腎癌術(shù)后患者(Ⅰ—Ⅲ期),男25例,女17例。中位年齡57(28-73)歲。應(yīng)用免疫熒光法測(cè)定患者接受聯(lián)合生物治療前1周和治療后1周的細(xì)胞免疫功能,并比較其變化。治療后1周進(jìn)行遲發(fā)型過敏反(DTH)試驗(yàn),觀察陽性率。 結(jié)果:應(yīng)用聯(lián)合生物治療1周后,患者的CD3+、CD3+CD4+、CD3+CD56+、CD4+/CD8+比值升高,與治療前比較差異有統(tǒng)計(jì)學(xué)意義(P㩳0.05);外周血中IL-2、IL-12、IFN-γ水平顯著升高(P㩳0.05),機(jī)體對(duì)腫瘤抗原的特異性DTH反應(yīng)明顯增強(qiáng),遲發(fā)型過敏反應(yīng)(DTH)陽性率達(dá)73.80%(31/42),無嚴(yán)重不良反應(yīng)。 結(jié)論:腎癌術(shù)后應(yīng)用原致敏DC+CIK聯(lián)合治療能有效提高患者的細(xì)胞免疫功能,改善免疫應(yīng)答,,可提高患者的生存獲益,是安全有效的。
[Abstract]:Background & objective: Renal cell carcinoma (RCC) is a common urological tumor. Early renal cell carcinoma (RCC) is mainly treated by surgery, but the recurrence rate is still high. RCC is insensitive to radiotherapy and chemotherapy. How to reduce recurrence and metastasis is an important direction of clinical research. Because of the strong immunogenicity of renal cell carcinoma, DC vaccine loaded with tumor antigen has become an effective method for the treatment of renal cell carcinoma. In this study, 42 cases of renal cell carcinoma treated with antigen sensitized DC combined with CIK were retrospectively analyzed. To observe its effect on immune function of patients with renal carcinoma after operation. Methods: from March 2012 to April 2014, 42 patients (25 males and 17 females) with stage 鈪
