涎腺腺泡细胞癌临床病理研究

1953年 Foote 和 Frazell 首次把腺泡细胞癌作为涎腺肿瘤的一个独立类型提出来。国外学者在60年代后对该肿瘤的临床病理特点作了一些研究,国内仅见少数报道。目前,该肿瘤之病理分型、临床病理联系等问题尚无明确一致的意见。本文对涎腺腺泡细胞癌的临床表     

涎腺肿瘤的诊断和治疗指南

涎腺肿瘤是常见的口腔颌面部肿瘤,病理类型十分复杂,以往对各种类型肿瘤的临床病理特点和生物学行为缺乏深入了解,治疗方面争议较多.近二十年国内专家对涎腺肿瘤的诊断和治疗进行了较系统的研究,明确了各型肿瘤的临床病理特点和生物学行为,对涎腺肿瘤的诊治原则达成许多共识.     

�������������

涎腺肿瘤是口腔颌面部较为常见的肿瘤,约占全部口腔颌面肿瘤疾患的1/5,其中上皮源性肿瘤占多数,其他组织来源(如间叶组织)肿瘤则比较少见.如同卵巢肿瘤,涎腺肿瘤的病理类型十分复杂,生物学行为也大相径庭.     

多模态超声对唾液腺肿瘤的鉴别诊断价值评价

目的: 探讨多模态超声对唾液腺良、恶性肿瘤的鉴别诊断价值,对有意义的参数进行赋值后,初步建立评分系统。方法: 对69例唾液腺肿瘤患者的77个肿瘤进行二维灰阶超声、彩色多普勒超声（CDFI）、超微血流成像(SMI)、实时组织弹性成像(RTE)及声脉冲辐射力成像(ARFI)检查,对有意义的参数赋值及组合得到不同评分方案,绘制各方案ROC曲线,将曲线下面积最大者作为最佳评分方案。采用SPSS 25.0软件包对数据进行统计学分析。结果: 肿瘤形态、边界、后方回声、血流阻力指数、RTE分级和ARFI平均值在唾液腺肿瘤良、恶性鉴别中具有统计学差异（P<0.05）。由以上6个参数组成的评分方案7为最佳评分方案,每个参数赋值1分,总分为6分,曲线下面积为0.944,以≥4分鉴别唾液腺肿瘤良恶性的敏感度、特异度、准确率分别为80.0%、98.4%和94.8%。结论: 多模态超声的应用及评分系统的建立,可有效提高超声对唾液腺肿瘤鉴别诊断的能力。     

Cytologic study of salivary gland tumors

Cytologic examination was performed on 22 known oral tumors of glandular origin. Cytologically, the cells of benign pleomorphic adenomas and an adenolymphoma could easily be identified as of benign tumor origin, but cytologic determination of malignancy was difficult in 11 of 14 malignant tumors due to lack of malignant features. A precise and comparative study of the morphologic details of the tumor cells with the histologic findings, however, seemed to suggest a possibility of determining the histologic type even in smear preparations.     

Surgical treatment of salivary gland tumors

Two hundred fifteen patients (74.14%) with benign tumors and 75 patients (25.86%) with malignant tumors of the salivary glands were analyzed. One hundred eighty-five of these patients were followed for 1 to 20 years postoperatively. Of 150 benign tumors, recurrence was noted in 15 cases (9.75%). The 5-year recurrence rate was 7.82%. With the malignant tumors, recurrence was noted in 16 patients (51.6%). The 5-year recurrence rate was 27.75%.     

涎腺肿瘤中端粒酶活性的检测及意义

Ultrasonic diagnosis of salivary gland diseases

Ultrasonic tomography was applied to diagnose salivary gland diseases in 201 patients. Malignant disorders were found in 53 cases, benign in 127, and inflammation in 21. The investigation yielded some echographic diagnostic criteria for tumors and non-tumorous salivary gland diseases.     

Prolactin binding in minor salivary gland tumors

An immunohistochemical study of 15 minor salivary gland tumors was initiated to determine if prolactin binding occurred in these tissues. Eight benign mixed tumors (BMT) and 7 adenoid cystic carcinomas (ACC) were selected at random from the surgical biopsy service of the MCV/VCU School of Dentistry, Department of Oral Pathology. The specimens were cut and mounted on slides along with sections of rat pituitary and rat ventral prostate which served as methodologic controls. Experimental specimens were incubated for 24 hours with varying concentrations of highly purified (iodination grade) rat prolactin; controls were incubated with vehicle. Following incubation the specimens were stained according to the Sternberger peroxidase-antiperoxidase method. Results showed dose-dependent staining for prolactin binding sites in 7 of 8 BMTs and 5 of 7 ACCs. The staining was wider in distribution than we observed in normal human minor salivary gland tissue. Binding was confined primarily to cells of duct origin in both types of tumor. In individual cells, staining was observed in diffuse cytoplasmic and perinuclear locations as well as in nuclei and apical regions. We conclude that two minor salivary gland neoplasms (BMT and ACC) exhibit prolactin binding at different cellular locations and in a more widespread pattern than was observed in normal minor salivary gland.
