目的:探讨肾癌伴下腔静脉癌栓的诊断及治疗。方法:回顾性分析2006年1月至2008年5月肾癌伴下腔静脉癌栓患者的临床资料,包括临床表现、术前诊断、手术方法和患者的预后。其中男1例,女1例,临床主要表现为腰痛、血尿及腹部肿物,术前经彩色多普勒超声、CT确诊有癌栓。结果:2例手术者中,术前多普勒超声及CT均可发现腔静脉癌栓。手术均行肾癌根治加腔静脉内癌栓切除,术后随访1例于术后一年肿瘤复发转移死亡,1例现无瘤存活。结论:彩色多普勒超声、CT对肾癌伴下腔静脉癌栓诊断率较高,可准确判断癌栓位置,对无淋巴结和远处转移者,积极行肾癌根治术加下腔静脉癌栓取出术是治疗肾癌合并静脉瘤栓的有效方法。 相似文献

目的：探讨老年性乳腺导管内乳头状瘤病的发病特点、诊断以及治疗方法。方法：对16例术前诊断为乳腺癌的老年患者,手术后病理证实的乳头状瘤病的病例进行回顾性分析和总结。结果：本组16例均以乳腺肿块为首发症状,其中2例既往有乳头溢液病史,16例术前均行彩超及乳腺钼靶摄片检查,考虑乳腺占位、癌可能性大。术后病理均诊断为乳头状瘤病,其中9例伴不典型增生。结论：老年性乳腺导管内乳头状瘤病最常见症状为乳腺肿块,术前行乳腺彩超及乳腺钼靶检查确诊率较低,仍需要术中行快速冰冻病理检查以明确诊断指导手术及治疗。乳腺导管内乳头状瘤病具有一定的恶变倾向。 相似文献

目的：研究分析HBME-1、CK19基因在甲状腺结节的表达状态及诊断价值。方法：回顾性分析天津肿瘤医院头颈外科1975．1～1998．1月收治的初治甲状腺乳头状癌行甲状腺癌联合根治术的有完整随访资料的93例患者临床、组织病理和免疫组织化学染色资料，与同期收治的15例结节性甲状腺肿、16例甲状腺腺瘤相比较。对常规HE染色证实上述病变的蜡块分别行HBME-1和CK19免疫组织化学染色。结果：93例甲状腺乳头状癌病例中，HBME-1基因阳性表达甲状腺乳头状癌为51例（54．8％），甲状腺良性病变为5例（16．1％）；CK19基因阳性表达甲状腺乳头状癌为39例（41．9％），甲状腺良性病变为4例（12．9％）。两种基因在甲状腺乳头状癌和良性病变中的阳性表达均存在统计学差异。HBME-1、CK19基因表达与甲状腺乳头状癌患者的性别、年龄、肿瘤大小、局部侵犯、颈淋巴结转移无明显相关性。结论：HBME-1、CK19基因在甲状腺乳头状癌中表达增强，在甲状腺结节的鉴别诊断中是有用的辅助手段。CK19在区分甲状腺乳头状癌和乳头状增生中是一个很好的标志物。 相似文献

甲状腺乳头状癌是恶性程度较低、最常见的甲状腺癌,肿瘤生长缓慢且大多预后良好,发病率呈逐年上升趋势.而又被称为隐匿性甲状腺癌的甲状腺微小乳头状癌所占甲状腺乳头状癌的相应比重也在不断增加.甲状腺微小乳头状癌主要是指肿瘤直径≤1.0cm的甲状腺癌,属于甲状腺癌的特殊类型.普遍认为甲状腺微小乳头状癌进展较慢、属于一种恶性程度较低的惰性癌,一般情况下预后较为良好.但存在极少数甲状腺微小乳头状癌临床表现的乳头状癌,表现出术后病情复发、颈部淋巴结转移等侵袭性病理特点,导致临床治疗方案存在争议与不统一.本文主要综述了甲状腺微小乳头状癌相关预后指标的研究进展. 相似文献

本文应用流式细胞术(Flow Cytometry,FCM)检测了102例石蜡包埋的乳癌组织的细胞核DNA含量,并探讨了DNA指数(DNA Index.DI)和S期细胞比例(S-phase Fraction,SPF)与临床预后因素及病人术后生存状况的关系。结果显示:16例为DNA二倍体,8例近二倍体,78例(77％)非整倍体。非整倍体癌较二倍体/近二倍体癌的SPF高。DI值与组织学分级、淋巴结状况、原发肿瘤大小和临床分期密切相关,而与病人诊断时的年龄无关。淋巴结转移阳性组较阴性组、晚期肿瘤(Ⅲ、Ⅳ期)比早期肿瘤(Ⅰ、Ⅱ期)的DI值高(P<0.05),而非整倍体率仅有降低的趋势但无显著性差异,说明DI值作为一个预后参数比倍性分析统计效率高。SPF与病人的各预后因素及生存情况无明显关系。二倍体/近二倍体癌病人较非整倍体癌病人的生存率高、无瘤生存时间长,说明流式细胞术DNA含量测定确实可为乳癌病人的预后提供有价值的信息。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
