【摘要】 目的 探讨外科手术治疗原发性腹膜后肿瘤的方法和影响患者预后的因素。 方法 回顾分析2002年5月-2008年5月收治的70例原发性腹膜后肿瘤患者的临床表现、影像学检查、手术治疗及随访情况。 结果 70例患者均进行了手术治疗，其中良性肿瘤20例（28.57%），恶性肿瘤50例（72.43%），良恶之比为1∶2.5；完整切除肿瘤者58例（82.86%），肿瘤部分切除者7例（10%），肿瘤广泛转移行组织活检者5例（7.14%），联合器官切除者18例（25.71%）。术后随访1~5年恶性肿瘤患者45例，其中肿瘤完全切除组1、3、5年的生存率分别为91.67%、66.67%、22.22%，肿瘤部分切除组分别为66.67%、33.33%、0%。两组比较差异有统计学（Plt;0.01）。研究发现肿瘤的大小、病理类型、是否完整切除是影响肿瘤局部复发、患者生存率的重要因素。 结论 早期诊断、充分的术前准备、肿瘤的全切除率能显著改善患者术后远期生存率。【Abstract】 Objective To investigate the surgical management for primary retroperitoneal tumors (PRT) and the factors influencing the prognosis after operation. Methods The clinical manifestation, image data, treatment and prognosis of 70 patients with primary retroperitoneal tumor from May 2002 to May 2008 were retrospectively analyzed. Results All of the patients with PRT had undergone the operations, in whom 20 (28.57%) had benign tumors and 50 (72.43%) had malignant tumors with a ratio of 1:2.5. Among these patients, 58 (82.86%) had complete resection, 7 (10%) had incomplete resection, five (7.14%) had surgical biopsies and 18 (25.71%) had combined resection of the organs. A total of 45 patients with malignant tumors were followed up for one month to five years. The one-, three-, and five-year survival rates of the patients in complete resection group was 91.67%, 66.67% and 22.22%, respectively; and was 66.67%, 33.33%, and 0%, respectively in incomplete resection group. The differences between the two groups were significant (Plt;0.001). The results showed that the completeness of tumor, sizes, and histological type were associated closely with local recurrence and prognosis. Conclusion Early diagnosis, sufficient preoperative preparation and complete tumor resection play important roles in reducing the recurrence and improving the long-term survival rate.
Objective To explore the correlation between interleukin-6 (IL-6) 174G/C polymorphism and ischemic stroke risks. Methods Systematic searches of electronic databases as CBM, CNKI, PubMed, MEDLINE and EMbase were performed. Meta-analysis was conducted by using RevMan 5.1.2 and Stata 11.0 software. The pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) were performed. Publication bias was tested by funnel plot, Egger’s regression test and Begg’s test. Sensitivity analysis was made by repeating the fixed effects model or random effects model Meta-analysis with each of the studies individually removed. Results A total of 11 publications with 12 studies were identified. The results of meta-analyses showed no significant difference was found in the correlation between IL-6 174G/C polymorphism and ischemic stroke risks (for G/C vs. G/G: OR=0.98, 95%CI 0.78 to 1.24; for C/C vs. G/G: OR=0.75, 95%CI 0.38 to 1.50; for dominant inheritance model: OR=0.93, 95%CI 0.68 to 1.28; for recessive inheritance model: OR=0.80, 95%CI 0.45 to 1.42). In the subgroup analyses on ethnicity, no significant correlation was found. But in the subgroup analyses on source of control population, the hospital-based subgroup showed IL-6 174G/C polymorphism was the protective factor of ischemic stroke (for G/C vs. G/G: OR=0.56, 95%CI 0.40 to 0.79; for C/C vs. G/G: OR=0.17, 95%CI 0.11 to 0.27; for dominant inheritance model: OR=0.40, 95%CI 0.29 to 0.55; for recessive inheritance model: OR=0.24, 95%CI 0.16 to 0.37). Conclusion Meta-analysis bly suggests that the correlation between IL-6 174 G/C polymorphism and ischemic stroke is not significantly different.
ObjectiveTo explore the safety and feasibility of contrast enhanced intraoperative ultrasonographyguided percutaneous radiofrequency ablation with artificial hydrothorax to hepatocellular carcinoma in the hepatic dome. MethodsThe clinical data of nine patients with hepatocellular carcinoma in the hepatic dome underwent ultrasonographyguided percutaneous radiofrequnecy ablation with artificial hydrothorax from January 2008 to June 2009 at Department of Hepatobiliopancreatic Surgery of West China Hospital were retrospectively analyzed. The perioperative results and recurrence of tumor were also analyzed. ResultsAll of nine patients with twelve tumors received successfully radiofrequency ablation with artificial hydrothorax of (2 444±464) ml (2 000-3 000 ml). The ablation time was 12-24 min (median 12 min), with an average of (15±5) min for each tumor. No hemothorax, pneumothorax, and death occurred during operation. One patient had ascites of 2 000 ml after ablation due to hypoalbuminenia, and ascites disappeared by infusion of abumin on 4 d after operation. The total volume of pleural drainage was 250-1 420 ml, with an average of (717±372) ml for each patient, and the drainage tube was withdrawn on 3-5 d after operation. The followup time was 7-23 months (mean 15 months). Tumor recurrence was found in three patients on 5, 6, and 7 months after operation, respectively. Of them, two patients were in stable disease stage after interventional and conservative therapy, respectively, and one case recurred at six months after operation and died of hypertensive heart disease and hepatic function deterioration at sixteen months after operation. The rest patients survived and no recurrence and metastasis was observed during the follow-up period.ConclusionThe technique of percutaneous radiofrequency ablation with artificial hydrothorax increases the feasibility of the minimal invasive treatment for hepatoma, which can be applied to hepatocellular carcinoma in the hepatic dome with high safety and clinical application value.
