Objective To investigate the histopathologic and clinical characteristics and proliferative activities of calcifying odontogenic cyst (COC). Methods 25 cases of COC were reviewed. The expression of proliferating cell nuclear antigen (PCNA) was studied using avidinbiotin peroxidase method and the number of nuclear organizing regions was calculated by means of the argyrophil staining technique in these cases. Results The cases were divided into 13 (52%) cysts and 12 (48%) neoplasms. Of the 12 neoplasms, 4...

The expression of proliferating cell nuclear antigen (PCNA) was studied using avidinbiotin peroxidase method and the number of nuclear organizing regions was calculated by means of the argyrophil staining technique in these cases. Results The cases were divided into 13 (52%) cysts and 12 (48%) neoplasms. Of the 12 neoplasms, 4 were odontogenic ghost cell carcinoma, with a PCNA labelling index (65.9%±7.3%) significantly higher than that of benign neoplastic variant (45.8%±11.5%, P<0.05) and cystic variant (29.3%±11.2%, P<0.01). The AgNOR counts was higher in the carcinomatous than benign or cystic variant. Conclusion The lesions show considerable diversity in structure and behavior. It is therefore proposed that quantiation of staining for NORassociated proteins and the PCNA labelling index are diagnostically useful in COC.

目的研究牙源性钙化囊肿(calcifyingodontogeniccyst,COC)的组织病理、临床特征及其细胞增殖活性。方法对25例COC的标本进行HE染色和组织学观察,增殖细胞核抗原(proliferatingcelnuclearantigen,PCNA)采用免疫组织化学法(ABC法)和银染核仁形成区(argyrophilstainingnucleolarorganizerregion,AgNOR)计数。结果25例COC中,13例为囊肿型,8例为良性肿瘤型,4例为恶性型,即牙源性影细胞癌。不同类型的COC中,细胞增殖活性不同。牙源性影细胞癌内PCNA的阳性表达率和AgNOR均数都显著高于其他类型的COC(P<0.01)。结论COC在结构和生物学行为上均具有较大的变异性。PCNA的阳性表达率及AgNOR计数有助于各型COC的诊断

Objective To evaluate the expression of nuclear factor-κB(NF-κB),Ki-67 and matrix metalloproteinase-9(MMP-9)in calcifying odontogenic cyst(COC),in order to investigate the proliferation and invasion of COC.Methods Twenty-six cases of COC were classified into calcifying cystic odontogenic tumor(CCOT),dentinogenic ghost cell tumor(DGCT)and ghost cell odontogenic carcinoma(GCOC) based on the WHO classification of odontogenic tumors in 2005.The specimens of COC and 10 classic ameloblastoma(AB)were examined immunohistochemically to determine the expression of NF-κB p65, Ki-67 and MMP-9.Results NF-κB was mainly detected in the cytoplasm of most tumor cells,but was only detected in the nucleus of few tumor cells(rate of nuclear staining<1%).The expression of Ki-67 was significantly higher in GCOC than in CCOT(P<0.001),DGCT(P<0.05)and AB(P<0.005).MMP-9 was detected both in tumor cells and stromal cells.GCOC showed significantly higher percentage of MMP-9 positive cases in stromal cells than CCOT,DGCT and AB(P<0.05).Conclusions NF-κB may minimally affect the progression and invasion of COC.GCOC shows significantly higher proliferative activity and aggressiveness than CCOT and DGCT.MMP-9 in stroma may play a key role in the invasion of GCOC.

目的检测核因子κB(NF-κB)、Ki-67和基质金属蛋白酶9(MMP-9)在牙源性钙化囊肿(COC)中的表达,探讨 COC 的增殖活性和侵袭性。方法根据2005年 WHO 关于牙源性肿瘤的分类标准,将26例被诊断为 COC 的病例分为牙源性钙化囊性瘤(calcifying cystic odontogenic tumor,CCOT)、成牙本质影细胞瘤(dentinogenic ghost cell tumor,DGCT)、牙源性影细胞癌(ghost cellodontogenic carcinoma,GCOC)3种病损,用免疫组化方法检测 NF-κB(p65)、Ki-67、MMP-9在 COC 和10例一般型成釉细胞瘤中的表达。结果 NF-κB主要在肿瘤细胞胞质中表达,偶见胞核表达(核阳性率<1%)。Ki-67在 GCOC 中的表达明显高于 CCOT(P<0.001)、DGCT(P<0.05)和成釉细胞瘤(P<0.005),差异有统计学意义。MMP-9在肿瘤细胞及间质细胞中均有表达,GCOC 间质细胞 MMP-9的阳性表达率明显高于其余3组良性牙源性肿瘤(P<0.05)。结论 NF-...
