对34例原发性肝癌(PLC)患者外周血可溶性白细胞介素-2受体(sIL-2R)、NK活性、T淋巴细胞亚群进行测定。结果:PLC患者sIL-2R水平明显高于健康对照组(P<0.01),NK活性、T淋巴细胞亚群CD3、CD4、CD4/CD比值均低于正常人(P<0.01),而CD8高于正常对照组(P<0.05)。Ⅱ、Ⅲ期PLC患者sIL-2R水平显著高于Ⅰ期患者(P<0.01)。sIL-2R水平≥1000u/ml、500~1000u/ml、<500u/ml者6个月内的死亡率分别为80.0%、29.4%、0%。肝癌切除术后2周sIL-2R水平较术前低(P<0.05),免疫治疗后4周sIL-2R水平亦较治疗前低(P<0.05)。细胞免疫水平都有所改善。提示测定外周血sIL-2R水平可作为PLC的免疫状态、病情严重程度、疗效观察及预后估计的生物学指标。 相似文献

目的:研究肝细胞肝癌(HCC)病人血清可溶性白细胞介素2受体(SIL-2R)水平的变化情况及其临床意义。方法:用酶联免疫吸附试验方法(ELISA)检测60例HCC病人、30例良性肝胆疾病病人以及20例健康对照者血清SIL-2R水平,结合临床资料分析其临床意义。结果:HCC组血清SIL-2R水平显著性高于其他两组(P<0.01),良性肝胆疾病组与健康对照组血清SIL-2R水平无显著性差异(P>0.05)。HCC组中血清SIL-2R水平与疾病分期有较好的相关性,随HCC分期升高,SIL-2R水平增高。血清SIL-2R水平与AFP水平无相关性(r=0.197,P>0.05)。血清SIL-2R水平可作为HCC早期诊断的良好指标,以100pmol/L为切割值,其灵敏度为81.7%,特异度为100%,诊断符合率90%。血清SIL-2R水平变化受手术因素影响。术后SIL-2R水平先升高后降低,降低程度与肿瘤切除与否有关。术后肿瘤复发病人血清SIL-2R水平升高。结论:血清SIL-2R水平可作为HCC病人早期诊断、病情判断、复发监测的重要指标。 相似文献

肝细胞肝癌病人血清IL-12、IL-2、sIL-2R水平的相关性 总被引:2,自引:0,他引:2
目的探讨肝细胞肝癌 (hepatocellularcarcinoma ,HCC)病人血清IL 12、IL 2、sIL 2R水平的相关关系。方法 6 0例HCC病人 ,随机分为 2组。试验组 (30例 )接受IL 2 (IL 2 10 0万U/d× 7d ,静脉点滴注射 )治疗 ;对照组 (30例 )没有接受生物治疗。两组基础治疗基本相似。采用酶联免疫吸附 (ELISA)法检测所有病人治疗前后血清IL 12、IL 2、sIL 2R水平变化。结果血清IL 12水平与血清IL 2水平正相关 ,IL 12与sIL 2R无关 ,IL 2与sIL 2R负相关。IL 2治疗后平均血清IL 12、IL 2、sIL 2R水平显著性升高。IL 2治疗后血清IL 12水平下降的HCC病人预后差。结论IL 12与IL 2之间可能存在一个反馈环路 ,sIL 2R是这个环路的负调节因素。IL 2治疗可刺激内源性IL 12释放。HCC病人的预后可能与IL 2诱生的IL 12变化有关 相似文献

Abstract The treatment options for primary irresectable rectal cancers are discussed. Assessment of tumour stage is the first step for an appropriate choice of treatment. Following a diagnosis of rectal cancer, a vast array of diagnostic procedures is available to determine its stage, and thereby its best treatment options. From the many (new) diagnostic options the merits and drawbacks are discussed. If a diagnosis of irresectability is made, further treatment options should include radiotherapy in most cases, some aspects of timing and application, i.e. intra-operative treatment are discussed. Chemotherapy options are manifold, the results are discussed and some new options are explored. 相似文献

高压氧治疗对严重烧伤患者血中sIL-2R和Fn含量变化的影响 总被引:2,自引:0,他引:2
目的通过观察高压氧治疗(Hyperbaric Oxygen Therapy,HBOT)对烧伤患者血中可溶性白介素2受体(Soluble interleukin-2 receptor,sIL-2R)及纤维连接蛋白(Fibronectin,Fn)含量的影响,探讨 HBOT 防治烧伤感染的价值。方法选择42例严重烧伤患者(烧伤面积>30%或Ⅲ度面积>10%),随机分为 HBOT 组(25例)和非 HBOT 组(17例),另选40名健康献血员作正常对照组。于伤后8h 及1,2,3,5,7,10,14,17,21,28,35天采集静脉血,ELISA 法测定血清 sIL-2R,火箭免疫电泳法测定其血浆 Fn,同时观察两组患者脓毒症发生率。结果非 HBOT 组:与正常对照组相比,伤后各时相点血清 sIL-2R 水平显著升高,而血浆 Fn 含量明显降低(P<0.05或 P<0.01);HBOT 组:与正常对照组相比,除伤后21天外,其余各时相点血清 sIL-2R 升高不明显;除伤后8h外,其余各时点血浆 Fn 降低不明显(P>0.05)。但与非 HBOT 组相比,伤后各时相点血清 sIL-2R均显著降低,而血浆 Fn 则明显增高(P<0.05或 P<0.01);与此同时,脓毒症发生率亦明显降低(P<0.05)。结论 HBOT 可显著降低严重烧伤患者血清 sIL-2R,而明显增高血浆 Fn,故对防治烧伤感染可能有益。 相似文献

Background: The objective of this study was to perform a non‐randomised prospective examination of the efficacy of adjuvant, preoperative chemo‐radiotherapy in patients with locally advanced rectal cancer. Methods: Between 1996 and 2001, patients presenting with biopsy‐proven, locally advanced, rectal cancers within 12 cm of the anal verge were referred for a long course of adjuvant chemo‐radiotherapy prior to their surgery. Locally advanced lesions were defined by either: (i) endoanal ultrasound showing at least full thickness penetration of the rectal wall (i.e. T3, T4); (ii) abdominal computed tomography scan showing infiltration of adjacent structures, or; (iii) clinical examination demonstrating a fixed lesion. All patients were followed through the hospital colorectal unit. A Kaplan?Meier survival analysis was used to determine survival and local recurrence rates. Results: There were 60 patients with a mean age of 61.5 years (range 33?77 years) with a sex distribution of males to females of 1.7?1.0. Curative resections were performed in 81% of these patients. The remainder (n = 12) were found to have either metastatic disease at operation (n = 5), inoperable disease (n = 2), or had positive resection margins on histology (n = 7). The mean follow up was 2.1 years (maximum 5.1 years). The overall 2‐year survival rate was 86.1% (95% CI ±5.4%). In patients undergoing curative resections, the overall 2‐year survival rate was 91.4% (95% CI ±4.8%), and the 2‐year disease free survival rate was 85.1% (95% CI ±6.2%). The 2‐year local recurrence rate was 7.5%. Conclusions: The use of adjuvant, preoperative, chemo‐radiotherapy in patients with locally advanced rectal cancer is associated with high short‐term survival and a low recurrence rate. 相似文献

Aim Multidisciplinary team meetings have been introduced as a result of developments in preoperative radiological tumour staging and neoadjuvant treatment. Multidisciplinary team recommendations will influence treatment decisions but their effect on patient outcome is unknown. The aim of this study was to assess outcome in relation to preoperative local and distant staging, with or without multidisciplinary team assessment. Methods A population‐based registry of all patients with rectal cancer, treated in the Stockholm region from 1995 to 2004, identified 303 patients with locally advanced primary rectal cancer. The patients were classified into three groups: group 1, preoperative local and distant radiological tumour staging with discussion at a multidisciplinary team meeting; group 2, preoperative staging but no multidisciplinary team assessment; and group 3, no proper preoperative radiological staging. Results Neoadjuvant treatment was more prevalent in groups 1 and 2 than in group 3. The incidence of R0 resection differed significantly between the groups (52% in group 1, 43% in group 2 and 21% in group 3; P < 0.001). Local tumour control was achieved in 57%, 36%, and 19% of patients in groups 1, 2 and 3, respectively (P < 0.001). The estimated overall 5‐year survival of patients was 30%, 28% and 12% in groups 1, 2 and 3, respectively. Conclusion Preoperative radiological tumour staging in patients with locally advanced primary rectal cancer and discussion at a multidisciplinary team meeting increases the proportion of patients receiving neoadjuvant treatment and cancer‐specific end‐points. 相似文献
