Adenoid cystic carcinoma has special biological characteristics and the tumor cells perineural invasion is the main reason of recurrence after tumor resection. 腺样囊性癌的生物学特性独特,其肿瘤细胞嗜神经侵袭是临床手术切除后肿瘤复发的主要因素。
Objective: To investigate the expression of Schwann cell marker S100 protein in salivary adenoid cystic carcinoma and try to find out the correlation of S100 expression and neural invasion of the tumor. 目的:对比研究雪旺细胞标志物S100蛋白在腺样囊性癌及粘液表皮样癌中的表达,探讨其与腺样囊性癌嗜神经侵袭间的关系。
Results The recurrent rate of benign mixed tumor, adenoid cystic carcinoma and malignant mixed tumor was 23. 0%, 18. 2% and 27. 8%, respectively. 结果良性混合瘤、腺样囊性癌和恶性混合瘤的复发率分别为23.0%、18.2%和27.8%。
As one of the most common malignant tumor of salivary gland, adenoid cystic carcinoma ( ACC) takes up 27% of all salivary gland carcinomas, 1% of head and neck carcinomas. 腺样囊性癌(adenoidcysticcarcinoma,ACC)是涎腺最常见的恶性肿瘤之一,占全部涎腺恶性肿瘤的27%,占头颈部恶性肿瘤的1%。
Salivary adenoid cystic carcinoma ( SACC) is one of the most common malignant tumor of the salivary glands. It has higher rate of invasion and distant metastasis. Therefore, it usually needs a supplementary chemotherapy after original tumor had been resected. 涎腺腺样囊性癌(SalivaryadenoidcysticcarcinomaSACC)是涎腺常见的恶性肿瘤,具有较强的侵袭能力和较高的转移和复发率。
Results: Local recurrence and blood vessel metastasis from adenoid cystic carcinoma of salivary glands are due to the invasive activity of the tumor. 结果:腺样囊性癌因其生物性特征,术后容易发生局部复发和血道转移。
Expression of DNA methyltransferases in salivary adenoid cystic carcinoma and its association with the CpG islands methylation of tumor suppressor genes 涎腺腺样囊性癌DNA甲基转移酶与抑癌基因甲基化
Other diseases which needed to be differentiated include thyroid-associated ophthalmopathy, carotid cavernous fistula, cysticercosis of extraocular muscle, pleomorphic adenoma, adenoid cystic carcinoma of lacrimal gland and malignant orbital tumor. 需要鉴别的疾病包括甲状腺相关眼病、颈动脉-海绵窦瘘、眼外肌豚囊尾蚴、泪腺混合瘤、泪腺腺样囊性癌以及眼眶恶性肿瘤。
Radical cystectomy with sparing of cavernous neuro-vascular bundle Objective: Salivary Adenoid cystic carcinoma ( SACC) is one of the most common malignant tumor of salivary glands. 目的:涎腺腺样囊性癌(salivaryadenoidcysticcarcinoma,SACC),是最常见的涎腺恶性肿瘤之一,该肿瘤具有侵袭性强、浸润性生长、早期沿神经血管束向远处扩展和转移等特征。
It seems that there is clear boundary between adenoid cystic carcinoma and peripheral tissue in salivary gland. But there is no envelope around the tumor, and the tumor often infiltrates peripheral tissue. 涎腺组织内发生的腺样囊性癌大体上似与周围组织界限清楚,但剖面所见肿物无包膜,仔细审视可见其向周围组织浸润情况。
