【摘要】 目的 探討外科手術治療原發性腹膜后腫瘤的方法和影響患者預后的因素。 方法 回顧分析2002年5月-2008年5月收治的70例原發性腹膜后腫瘤患者的臨床表現、影像學檢查、手術治療及隨訪情況。 結果 70例患者均進行了手術治療，其中良性腫瘤20例（28.57%），惡性腫瘤50例（72.43%），良惡之比為1∶2.5；完整切除腫瘤者58例（82.86%），腫瘤部分切除者7例（10%），腫瘤廣泛轉移行組織活檢者5例（7.14%），聯合器官切除者18例（25.71%）。術后隨訪1~5年惡性腫瘤患者45例，其中腫瘤完全切除組1、3、5年的生存率分別為91.67%、66.67%、22.22%，腫瘤部分切除組分別為66.67%、33.33%、0%。兩組比較差異有統計學（Plt;0.01）。研究發現腫瘤的大小、病理類型、是否完整切除是影響腫瘤局部復發、患者生存率的重要因素。 結論 早期診斷、充分的術前準備、腫瘤的全切除率能顯著改善患者術后遠期生存率。【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.
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.
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 identi?ed. The results of meta-analyses showed no signi?cant 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 signi?cant 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.
