  • The Immunohistochemistry Expressions and Significance of ΔNp63, Ki67 in the Transitional Cell Carcinoma of Bladder

    目的:探讨ΔNp63和Ki67在膀胱移行上皮癌(transitional cell carcinoma of bladder,TCCB)中的免疫组化表达及与膀胱癌病理分级、临床病理分期和预后的相关性。方法:随机选择2006~2007年间56例TCCB和12例正常膀胱黏膜病理切片用SP免疫组化行ΔNp63和Ki67检测,将结果与病理分级、分期和预后进行分析。结果:ΔNp63和Ki67在膀胱移行细胞癌中的阳性表达率明显高于正常膀胱黏膜(Plt;005)。ΔNp63和Ki67在低分化、浸润性癌组织中的阳性表达率明显高于高分化、浅表性癌组织,在膀胱癌的病理分级和临床分期之间表达差异有统计学意义(Plt;005)。ΔNp63和Ki67在复发病例中的阳性表达率显著高于初发病例(Plt;005)。采用Spearman等级相关性分析对ΔNp63和Ki67在TCCB中的表达进行比较,ΔNp63与Ki67呈正相关,rs′为0316,且Plt;005。结论:ΔNp63和Ki67与膀胱癌的临床病理分级和分期及预后密切相关,随膀胱癌分化程度的降低和浸润程度的增加而增强。ΔNp63和Ki67在TCCB的进展中可能有相互协同作用,ΔNp63可能通过促进细胞增殖发挥促癌作用,联合检测ΔNp63和Ki67可以作为判断TCCB的预后的肿瘤标记物。

  • Radiofrequency Ablation in Treatment for Hepatocellular Carcinoma(Report of 58 Cases)

    目的 探讨射频消融术在无法实施手术的原发性肝癌患者中的临床应用效果。方法 回顾性分析2007年9月至2011年3月期间我院收治的58例由于各种原因无法手术治疗的大肝癌(>5cm)并接受射频消融治疗患者的临床资料,射频消融前后结合超声造影的方法,术后随访并定期复查血清甲胎蛋白水平和超声造影或者肝脏增强CT。结果 58例中无一例发生与射频消融相关的死亡,22例达到完全消融(37.9%,22/58)。共51例(87.9%,51/58)获得随访,随访至2012年5月,随访时间(12.6±6.4)个月(2~21个月),随访12个月以上患者有20例(39.2%,20/51),有10例(19.6%,10/51)无肿瘤复发或者转移的迹象。22例达到完全消融的患者无瘤生存时间为(13.6±10.4)个月(3~21个月);36例未能达到完全消融的患者中,有19例随访期间死亡,生存时间(8.3±6.1)个月(4~16个月)。结论 由于各种原因不能接受手术的大肝癌患者,射频消融作为一种有效、安全治疗方法,部分能达到完全消融的效果,而部分作为姑息性治疗手段,能一定程度上减轻患者的疼痛,达到提高生活质量的目的。

  • Clinical Experience of Laparoscopic Hepatectomy (Report of 25 Cases)

    ObjectiveTo evaluate the safety and feasibility of laparoscopic hepatectomy. Methods A total of 25 patients with hepatocellular carcinoma or liver hemangioma received laparoscopic hepatectomy, and perioperative results were analyzed. ResultsOnly one patient was converted to open hepatectomy because of massive hemorrhage. Blood loss of all patients during operation ranged from 100-1 200 ml with an average of 400 ml. The total blood volume of transfusion was 200-1 000 ml (mean 400 ml) in 14 patients. The operative time was 0.8-4.0 h (mean 2.3 h). All patients had no complications such as bile leakage and infection, and discharged from hospital in 5-10 d (mean 8 d) after operation. ConclusionLaparoscopic hepatectomy is safe and feasible to some liver diseases, but should be used with caution for the patients with tumor diameter over 9 cm and hepatic large vessels invaded by cancer.
