Arsenic trioxide (As2O3) reduces the invasive and metastatic properties of cervical cancer cells in vitro and in vivo

OBJECTIVES: Arsenic trioxide (As(2)O(3)) was found to induce apoptosis in certain types of cancer cells including acute promyelocytic leukemia, and recently in solid tumors. We have previously demonstrated that As(2)O(3) has a therapeutic effect on cervical cancer by apoptosis promotion in vitro and in vivo. Here we further our study on the role of arsenic trioxide in regulating invasive activity of cervical cancer cells in vitro and in vivo. METHODS: The effects of As(2)O(3) on human cervical cancer cell lines (HeLa, SiHa, Caski) adhesion, migration and invasion were observed by means of cell adhesion test, cell migration test and cell invasion test. The effects of As(2)O(3) on p-IkappaB, MMP-2, E-cadherin, caveolin-1 and beta-catenin protein expressions of tumor cells were determined by Western blot. In addition, the effects of As(2)O(3) on NF-kappaB activity of tumor cells were analyzed by immunoblot in whole lysates, cytosol and nucleus, respectively. In animal experiments, cervical cancer cells TC-1 were injected into tail veins of C57BL/6 mice and then the mice were treated by intraperitoneal injection of different doses As(2)O(3). Lung weights and the foci on the surface of lungs were measured. RESULTS: As(2)O(3) inhibited attachment of tumor cells to Fibronectin and Matrigel, reduced cell motility and inhibited tumor invasion potential. As(2)O(3) treatment also resulted in a positive regulation of caveolin-1, upregulation of E-cadherin and decreased activity of beta-catenin, NF-kappaB and NF-kappaB-regulated gene MMP-2. In animal experiments, lung weights in PBS group (0.31+/-0.07 g) were significantly elevated compared with those in As(2)O(3)-treated groups (0.21+/-0.03 g and 0.17+/-0.03 g) also As(2)O(3) reduced number of metastatic lesions of lungs (15.4+/-3.5 vs. 8.3+/-2.0 and 6.3+/-2.3) in a dose-dependent manner. CONCLUSIONS: This study is the first to report the effectiveness of As(2)O(3) as an inhibitor of cervical cancer invasion both in vitro and in vivo, suggesting a potential clinical application of As(2)O(3) in cervical cancer therapies combining apoptosis induction and metastasis inhibition.

三个癌瘤以上的多原发恶性肿瘤

目的：探讨3个癌瘤以上的多原发恶性肿瘤（MPMNs）的流行病学和临床特点。方法：回顾性分析1958年-2001年收治的125例患者的发病率、发病年龄、性别比、间隔时间、好发部位。结果：3个癌瘤以上的MPMNs的发病率为0.090％,其中3、4、5MPMNs的发病率分别为0.078％、0.009％和0.001％;平均发病年龄为64岁。男：女为1.0：1.2。平均间隔时间为7.1年,第1和2、2和3、3和4、4和5原发癌的间隔时间渐短,从5、7减至2.4年。3年内为相邻两癌的高发时间。好发部位：按单一器官计3个癌瘤原发癌依次为：大肠、乳腺、肺、食管、子宫和皮肤;4个癌瘤原发癌为：大肠、乳腺、皮肤、胃、子宫和膀胱;5个癌瘤原发癌为：大肠、乳腺、皮肤、腮腺。结论：3个癌瘤以上的MPMNs的发生率有增多的倾向;发病年龄在逐渐增大;女性多于男性;第1和2、2和3、3和4、4和5原发癌的时间间隔逐渐缩短;好发器官为同一器官,成对器官和同系统的器官。     

贲门癌术后吻合口复发的再手术治疗

目的探讨贲门癌术后吻合口复发外科再治疗的手术指征及术式选择.方法对23例贲门癌术后吻合口复发,再手术患者的临床资料进行回顾性分析.结果本组患者的手术切除率、手术并发症发生率及手术病死率分别为69.6%、17.4%和8.7%,胸、腹腔粘连率为87.0%.肿瘤切除患者平均术后存活15.0个月,明显长于未切除患者的4.1个月(P＜0.05).无淋巴结转移患者术后存活21.3个月,虽较有淋巴结转移患者的10.2个月长,但差异无显著性意义(P＞0.05).根治性切除和姑息性切除患者的术后生存期分别为15.8个月和13.3个月,差异无显著性意义(P＞0.05).结论由于胸、腹腔的广泛粘连及二次手术后的消化道重建,贲门癌术后吻合口复发再手术有一定难度,手术风险较大,加之贲门癌患者本身预后较差,因此应严格把握手术指征.术式选择应根据患者病变的分期、分级等具体情况而定.     

重组人p53腺病毒联合温热顺铂不同用药方式下对人结肠癌细胞株的抑制作用

目的研究rAd-p53与热化疗以不同序贯方式联合应用对不同p53基因状态的结肠癌细胞的抑制作用。方法通过体外细胞培养,采用PT-PCR和Western blot检测验证细胞内不同p53基因状态,利用MTT法检测rAd-p53与42℃热浴顺铂的IC30,以及用药物联合指数计算法观察rAd-p53与42℃热浴顺铂不同用药模式下对不同p53基因状态的结肠癌细胞的抑制作用。结果在p53基因野生型的HCT116+/+细胞中42℃热浴顺铂与rAd-p53同时给药表现为协同作用,42℃热浴顺铂序贯rAd-p53给药模式表现为近似叠加作用,rAd-p53序贯42℃热浴顺铂用药模式表现为拮抗作用。在p53基因敲除的HCT116-/-细胞中,42℃热浴顺铂与rAd-p53同时给药表现为强协同作用,42℃热浴顺铂序贯rAd-p53给药模式表现为协同作用,rAd-p53序贯42℃热浴顺铂用药模式表现为拮抗作用。结论在结肠癌细胞中42℃热浴顺铂与rAd-p53在同时给药的模式下疗效最好,然而不同结肠癌细胞中p53基因状况决定其产生不同作用效果,缺失型p53基因细胞协同效果优于野生型p53基因细胞。

不同年龄段胃癌患者卵巢转移的危险因素与预后

目的探讨不同年龄胃癌患者卵巢转移的危险因素及预后。方法回顾性分析1994年至2001年经手术治疗的345例女性胃癌患者的临床病理资料,利用Logistic回归及Cox回归分析胃癌卵巢转移的危险因素及预后因素。结果同时性卵巢癌患者22例,转移率为6.4%;根治术后卵巢转移的患者24例,2年累计卵巢转移率为8.9%(24/271)。淋巴结转移数目大于7个(相对危险度9.186,95%可信区间3.773～22.365,P<0.001)、年龄小于50岁(相对危险度6.713,95%可信区间2.633～17.115,P<0.001)是卵巢转移的独立危险因素。有35例患者行手术切除,其中位生存时间11个月,多因素分析显示根治性切除是患者生存的独立相关因素(相对危险度0.056,95%可信区间0.015～0.215,P<0.001)。结论年轻患者更容易出现卵巢转移,年龄小于50岁和淋巴结转移数目超过7个是胃癌卵巢转移的重要危险因素。其预后取决于病变是否可获根治性切除。
