阑尾黏液性肿瘤6例临床病理分析 总被引:1,自引:0,他引:1
目的探讨阑尾黏液性肿瘤的病理学特点、诊断及鉴别诊断方法。方法回顾性分析6例阑尾黏液性肿瘤的临床资料、组织病理学和免疫组化特点及随访结果。结果 6例患者中男女各3例,年龄41~71岁。无典型临床表现,术前一般不能做出准确诊断。阑尾增粗、腹盆腔黏液及卵巢黏液性肿瘤,为阑尾黏液性肿瘤的重要诊断依据。肿瘤性上皮和(或)黏液累及范围与阑尾黏液性肿瘤病理诊断及预后有关;卵巢及腹盆腔病灶继发于阑尾黏液性肿瘤,有赖于免疫组化CK20+、CK7-、MUC-1-、MUC-2+、CEA+、CDX-2+、ER-支持。结论阑尾明显增粗,且有黏液、黏液性腹腔积液及双侧卵巢黏液性肿瘤时,应高度怀疑阑尾黏液性肿瘤。肿瘤性上皮侵犯深度、范围,对判断肿瘤良恶性最为重要。免疫组化结果对确定卵巢、腹膜病灶的来源具有决定性作用。 相似文献

目的:研究粘蛋白MUC1在卵巢浆液性肿瘤中的表达及其临床意义。方法:应用免疫组织化学SP法检测53例卵巢浆液性囊腺癌、20例交界性卵巢浆液性囊腺瘤、20例卵巢浆液性囊腺瘤、20例正常卵巢组织中MUC1的表达情况。结果:MUC1在卵巢浆液性囊腺癌中的阳性表达率为88.7%,略高于交界性浆液性囊腺瘤中的表达(70%)(P=0.1172),明显高于良性卵巢浆液性囊腺瘤(35%)及正常卵巢组织(30%)中的表达(P<0.05)。MUC1的阳性表达与卵巢浆液性囊腺癌的临床分期有关(P<0.05),与年龄、组织分级和淋巴结转移无关(P>0.05)。结论:粘蛋白MUC1在卵巢浆液性囊腺癌的发生、发展中起重要作用,MUC1可作为判断卵巢浆液性囊腺癌生物学行为和恶性潜能的参考指标。 相似文献

背景与目的:卵巢黏液性肿瘤是卵巢上皮性肿瘤的主要亚型之一,其恶变机制目前尚未明确。泛素化是人体主要的翻译后修饰机制,并与肿瘤密切相关。去泛素化酶可通过逆转泛素化过程从而影响肿瘤的发生、发展。该研究旨在分析编码人体最主要的去泛素化酶的癌基因泛素醛结合物1(OTU deubiquitinase,ubiquitin aldehyde binding 1,OTUB1)在卵巢黏液性肿瘤中的蛋白表达及临床应用。方法:收集2010-2015年复旦大学附属妇产科医院病理科诊断的卵巢良性黏液性囊腺瘤、卵巢交界性黏液性肿瘤及卵巢原发性黏液性癌病例共90例,收集临床病理资料,完成OTUB1的免疫组织化学法表达实验并作统计分析。结果:90例卵巢黏液性肿瘤中,卵巢良性黏液性囊腺瘤有14例,卵巢交界性黏液性肿瘤有17例,卵巢原发性黏液性癌有59例。OTUB1在卵巢原发性黏液性癌的蛋白表达率及阳性程度显著高于卵巢良性黏液性囊腺瘤(P<0.01);OTUB1在卵巢交界性黏液性肿瘤中上皮内癌的阳性率显著高于肠型交界性黏液性肿瘤(P<0.01);随着FIGO分期增高,OTUB1的阳性率及阳性程度增加(P<0.05);OTUB1在输卵管有累及的患者中表达率及阳性程度均高于未累及者(P<0.05);OTUB1在子宫和大网膜累及的患者中阳性率及阳性程度均高于未累及者(P<0.05);OTUB1在有淋巴结转移的患者中表达率及阳性程度均高于无转移者(P<0.05)。结论:OTUB1在卵巢原发性黏液性癌中的蛋白表达水平明显高于卵巢良性黏液性囊腺瘤,并且和FIGO分期及肿瘤侵袭转移性高度相关。在临床病理中可将OTUB1作为卵巢黏液性肿瘤恶变与否的评价指标及肿瘤进展的辅助判别指标。 相似文献

Pseudomyxoma peritonei is only rarely seen in conjunction with primary ovarian tumors. It has been suggested that only ruptured mucinous tumors arising in ovarian mature cystic teratomas can result in this clinical picture. We describe a case of a late invasive recurrence of a mucinous intestinal-type borderline ovarian tumor arising from a mature teratoma after complete surgical debulking. Borderline ovarian tumors behave indolently in the overwhelming majority of cases, and the prognosis is therefore usually outstanding. 相似文献

BACKGROUND. Mucinous tumors of the appendix and ovary are known to occur together in association with pseudomyxoma peritonei. It has been postulated that this association may be attributable to the development of independent tumors or to metastasis from one site to another. METHODS AND RESULTS. This article reports two patients with concomitant mucinous ovarian and appendiceal tumors in the absence of pseudomyxoma peritonei. CONCLUSIONS. The evidence suggests that these tumors are independent primary neoplasms that develop as a result of neoplastic field change that affects colonic-type epithelium. 相似文献

Pseudomyxoma peritonei (PMP) is a rare tumor syndrome that can be diagnosed in association with mucinous ovarian tumors of low malignant potential. Surgical debulking is the primary treatment modality as chemotherapy has generally proven ineffective in this slowly progressive tumor. When patients with PMP are not surgical candidates, there is no effective treatment, and patients will die of progressive disease. We report two patients with PMP with associated mucinous ovarian tumor of low malignant potential treated with Bevacizumab therapy. Both patients demonstrated disease response to single agent Bevacizumab therapy. One patient had a prolonged response while on therapy, remained stable for 6 months when treatment was held, and then after progressing responded to a second course of therapy. We discuss here (1) the clinical features which may predict a better response to Bevacizumab therapy, and (2) evidence for the use of chemotherapy for inoperable PMP. These cases suggest that Bevacizumab may represent a rare effective therapy for patients with inoperable PMP with ovarian involvement and should be considered for clinical trials in this patient population.Key Words: Pseudomyxoma, Ovarian tumor of low malignant potential, Bevacizumab 相似文献

Ovarian cancer is the most common cause of gynecologic cancer death. Both morphologically and immunohistochemically, metastatic mucinous tumors are the best mimickers of mucinous ovarian tumors; its pathogenesis still remains a mystery. PAX2 and PAX8 immunohisyochemistries are useful for differentiating numerous primary tumour types from metastatic ones. There are few studies in literature about PAX expressions in mucinous and seromucinous tumors. None of these are takes into account the histologic type (whether it is seromucinous or mucinous) or the metastatic origin. With this purpose hematoxylin and eosine slides of ovarian mucinous and seromucinous tumors were re-evaluated and one block was chosen for each case. The study included 76 ovarian mucinous and seromucinous tumors of the ovary reported in Hacettepe University department of pathology between 2000 and 2013. Tissue microarray (TMA) was designed from the chosen blocks, PAX2, PAX8, CDX2 immunostains was preformed to the TMA slides. As a result, most of the metastatic cases were negative for PAX2 (91.2 %) and PAX8 (86.3 %), many were diffusely and strongly positive for CDX2 (68.2 %). Seromucinous tumors were devoid of CDX2 expression; but all cases (except one) displayed strong and diffuse positivity with PAX8. In other words differing from mucinous tumors, seromucinous tumors show strong PAX8 positivity–similar to serous tumors. This study shows that PAX8 and CDX2 could be useful in differentiating primary mucinous from metastatic tumor. Furthermore unlike the homogeneity in seromucinous tumors for PAX8 and CDX2 mucinous tumors shows heterogeneity with different expression patterns. 相似文献

Pseudomyxoma peritonei is a rare neoplastic condition in that gelatinous intraperitoneal fluid collections and mucinous implants on the peritoneal surfaces and omentum are found. The pathological origin is usually an adenoma or well-differentiated adenocarcinoma of the appendix. A smaller number of cases arises from ovarian tumors. We report two unusual cases of pseudomyxoma peritonei. As a child, the first patient underwent several surgical procedures of the large bowel to relieve the consequences of Hirschsprung disease that were complicated by recurrent enteric fistulae. Colonic epithelial cells, with neoplastic changes due to chronic inflammation in the presence of enteric fistulae, were probably dislocated during these episodes, causing pseudomyxoma peritonei. In the second patient, pseudomyxoma was caused by intraperitoneal seeding of a mucinous urachal adenocarcinoma. We hypothesize that seeding of mucus producing epithelial cells into the abdominal cavity may result in this rare entity called pseudomyxoma peritonei, regardless of the source. 相似文献
