Methods:A total of 90 patients with primary gastric cancer who received treatment in Tianyou Hospital Affiliated to Wuhan University of Science & Technology between January 2014 and May 2016 were collected and divided into control group and observation group according to the random number table method, 45 cases in each group. The control group of patients received routine systemic intravenous chemotherapy + surgical treatment, and the observation group of patients received systemic intravenous chemotherapy combined with local arterial perfusion chemoembolization + surgical treatment. Levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were compared between the two groups of patients before and after chemotherapy.Results:Before chemotherapy, the levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were not significantly different between the two groups of patients;after chemotherapy, serum CEA, CA724, CA242, AFP, VEGF, Ang-2, COX2 and PD-ECGF levels of observation group were lower than those of control group, andiASPP, p130Cas, ERBB2 and C-myc mRNA expression in gastric cancer tissue were lower than those of control group while GKN1, p16, PTEN, TSPYL5 and merlin mRNA expression in gastric cancer tissue were higher than those of control group.Conclusions: Preoperative systemic intravenous chemotherapy combined with regional arterial perfusion chemoembolization can effectively reduce the malignancy of locally advanced gastric cancer and provide favorable conditions for the operation.展开更多
目的:观察术前新辅助化疗治疗浸润性膀胱癌的临床疗效。方法:对27例平均年龄68岁、有全膀胱切除指征而无法耐受或不愿接受膀胱全切的浸润性膀胱癌患者行骼内动脉化疗并栓塞联合手术治疗,观察膀胱保留率、降级降期率、肿瘤复发率,Kaplan-...目的:观察术前新辅助化疗治疗浸润性膀胱癌的临床疗效。方法:对27例平均年龄68岁、有全膀胱切除指征而无法耐受或不愿接受膀胱全切的浸润性膀胱癌患者行骼内动脉化疗并栓塞联合手术治疗,观察膀胱保留率、降级降期率、肿瘤复发率,Kaplan-Meier法计算总生存率、无瘤生存率,并绘制生存曲线。结果:髂内动脉化疗、栓塞后,22例患者膀胱肿瘤缩小约81.5%,无变化5例;肿瘤临床分期降低21例(有效率77.8%),无变化6例;病理分级降低12例(降级率44.4%),分级不变15例。共24例患者得以保留膀胱,其中21例行经尿道膀胱肿瘤切除术(transurethral resection of the bladder,TURB),3例行膀胱部分切除术(膀胱保留率88.9%)。3例接受根治性膀胱全切术。术后1、2、3、5年分别复发4例(14.8%)、7例(25.9%)、11例(40.7%)、14例(51.9%)。2例随访11个月和23个月发现肿瘤远处转移后死亡,1例膀胱切口种植转移,局部切除后再发,带瘤生存,术后3年死于肿瘤进展,2例腺癌5年内死于肿瘤进展。至随访截止日期,死于术后肿瘤进展共5例。27例患者1、2、3、5年无瘤生存率分别为88.9%、73.6%、58.1%、41.4%,5年总生存率66.0%。结论:有选择地对部分浸润性膀胱癌患者施行术前髂内动脉灌注化疗、栓塞,联合手术等综合性治疗措施以保留功能性膀胱确实可行,但合理评价其在浸润性膀胱癌治疗中的应用价值尚需要进一步研究证实。展开更多
