乳头状癌

objective to analyze the ct appearance of thyroid carcinoma and the differential diagnosis of various thyroid disease.methods 83 cases of thyroid carcinoma and 119 cases of various benign disease with surgical and pathologically proved were analyzed retrospectively.results the ct findings of 83 cases of thyroid carcinoma include:ill defined nodules boundary (n=62),irregular necrosis(n=59),cystic(n=23),"peninsula" enhancing tubercles around the tumour(n=25),"mastoid" tubercles around the tumour(n=11),calcification(n=55) including large scale(n=27) and local(n=28),trachea invasion(n=15),neck or supraclavicular lymph node metastasis(n=27),the accurate of ct to differentia benignancy from malignancy on thyroid disease was 93.6%(189/202).conclusions "peninsula" enhancing tubercles was the characteristic sing of thyroid carcinoma,"mastoid" enhancing tubercles or large scale calcification was the affirmative sign,the ct signs was vary useful to differentiating thyroid disease.

摘 要］目的：分析甲状腺癌的ct表现及鉴别诊断要点。方法：回顾性分析经手术病理证实的83例甲状腺癌和119例甲状腺良性病变的ct表现，归纳总结不同病变的ct特征。结果：83例甲状腺癌中：边界不清62例，不规则坏死59例，囊性变23例，出现"半岛状"强化结节25例，"乳头状"强化结节11例，钙化55例(其中弥漫性钙化27例、局灶钙化28例)，侵犯气管15例，颈部或锁骨上淋巴结肿大27例，ct对甲状腺病变的良恶性鉴别诊断符合率93.6%(189/202)。结论："半岛状"强化结节是甲状腺癌的特征性表现，"乳头状"强化结节及弥漫性钙化可做为甲状腺癌的肯定性征象，掌握各种甲状腺病变的ct表现特点，对病变的定性诊断及鉴别诊断具有重要意义。

Microspectrophotometer was used to measure the DNA content of 3 mucosa specimens of normal blad- der, 5 papillomas and 15 bladder transitional cell carcinomas. The transitional cell carcinoma was divided into 3 gradesand each grade group comprised 5 cases.

应用显微分光光度计检测膀耽正常粘膜、膀胱乳头状瘤及膀胱移行细胞癌共23倒(正常粘膜3例、乳头状瘤5例及移行细胞癌15例，移行细胞癌分三级，Ⅰ级、Ⅱ级、Ⅲ各5例)，其结果显示，正常粘膜上皮细胞和乳头状瘤细胞核及移行细胞癌细胞核Ⅰ、Ⅱ、Ⅲ各组之间胞核DNA含量均值有显著的差别(P.05～0.01)。

Primitive pathology is diagnosed include to be not epithelioma of road of make water of shape of tit of wellability low level (epithelioma of road of make water of shape of tit of high level of N=23), blame wellability (N=6), low the way of tit shape make water that spends malign potential is epithelial tumor (tumour of shape of N=5), tit (N=3),...

原始病理诊断包括非浸润性低级别乳头状尿路上皮癌(n=23)、非浸润性高级别乳头状尿路上皮癌(n=6)、低度恶性潜能的乳头状尿路上皮肿瘤(n=5)、乳头状瘤(n=3)、尿路上皮肿瘤(n=2)、原位癌(n=1)以及鳞形细胞癌n。。。

The results suggest that papillary renal cell carcinoma with PNA-receptor originate from lower nephron. PNA-receptor may be related with the biologic behavior of tumor cells.

提示一些PNA受体阳性表达的乳头状肾细胞癌可能起源于下肾单位，PNA受体与肿瘤细胞恶性生物学行为有关，PNA染色可作为乳头状肾细胞癌的预后指标。

The results suggest that EGFR overexpression, nm23-H1 low expression and negative correlation of their expression may be one of the causes of PTC?s biological feature of lymph node metastasis; serail tests of EGFR, nm23-H1 could be used as the markers to evaluate lymph node metastasis of PTC.

甲状腺乳头状腺癌EGFR的过表达，nm23-H1的低表达，二者表达的失平衡是其易于淋巴结转移的原因之一，EGFR，nm23-H1联用可作为甲状腺乳头状腺癌淋巴结转移的评价指标。

Many clear cell carcinomas show papillary growth; however, the cores of their often bulbous papillae are often hyalinized or myxoid rather than fibrovascular seen in papillary serous carcinoma.

许多透明细胞癌呈乳头状生长；然而，乳头轴心通常呈球茎状，且通常透明变性或粘液样变，而不是乳头状浆液性癌那样的纤维血管轴心。

What was observed under a light microscope included: tumor cells were mulberry and micropapillaryshaped or it was of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes; immunohistochemical staining showed EMA positive location was both at outward surface of glandule duct and at micropapillarylike cancer nest.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙。微乳头缺乏纤维血管轴心。免疫组化染色EMA阳性部位在癌细胞巢团或微乳头状、腺管的外表面。

Results There were fifteen cases of primary peritoneal serous papillary carcinoma and two cases of mucinous carcinoma.

结果浆液性乳头状腺癌15例，黏液性乳头状腺癌2例。

CONCLUSION摘要: Our successfully constructed cDNA libraries are fulllength libraries with high efficiency and can be screened by probes and antibodies to find the associated genes of the renal papillary adenocarcinoma.

结论摘要：我们构建的人肾乳头状腺癌及癌旁组织cDNA文库为高效、全长cDNA文库，可以用做探针、抗体等免疫学筛选，进一步探寻和肾乳头状腺癌相关的基因。
