Argyrophilic nucleolar organizer regions in breast carcinoma. Correlation with DNA flow cytometry, histopathology, and lymph node status.

Argyrophilic nucleolar organizer regions (AgNOR) have been correlated with proliferative activity of neoplasms. Increased AgNOR may reflect increased proliferative activity of cells or ploidy. To explore this hypothesis, 41 breast carcinomas were processed for AgNOR silver staining and DNA flow cytometry. AgNOR counts were expressed as mean AgNOR/nucleus and percentage of tumor cells with more than five AgNOR/nucleus. The first count was designated mean AgNOR or mAgNOR, and the second count was designated AgNOR proliferative index or pAgNOR. Using Mantel-Haensel statistical analysis, carcinomas that exhibited mAgNOR of 2.4 or more had a high likelihood of aneuploidy (P less than 0.0001), an S-phase fraction of more than 5.8% (P less than 0.003), or a diameter greater than 2 cm (P less than 0.007). In addition, tumors with pAgNOR of 8% or more showed a statistically significant correlation with aneuploidy (P less than 0.004), tumor grade (P less than 0.04), and a more significant one with high S-phase fraction (P less than 0.0001). No significant correlation was obtained between pAgNOR and tumor size or lymph node status. These data indicate that AgNOR quantitation reflects changes in DNA ploidy and cell proliferation. They also suggest that the mean AgNOR counts correlate best with the DNA mass or ploidy and that the frequency of cells with higher AgNOR count best reflects proliferative activity or S-phase fraction.     

恶性肿瘤DNA倍体异质性与细胞生物学特性的关系

目的 探讨恶性肿瘤组织DNA倍体异质性与癌细胞生物学特性的关系.方法 采用流式细胞术(FCM)检测163例恶性肿瘤组织DNA倍体异质性,并分析DNA倍体异质性与肿瘤细胞DNA指数(DI)、细胞凋亡(Apo)百分比、S期细胞百分比(SPF)以及DNA倍体类型等细胞生物学特性参数之间的相关性.结果 各种恶性肿瘤的DNA倍体异质性明显不同,在6种肿瘤中,DNA倍体异质体检出率大小分布顺序与DNA异倍体的分布十分相似.恶性肿瘤组织的DI值与DNA异质体检出率呈显著正相关(r=0.872 4,P＜0.05).异质体的DNA异倍体检出率(100.0%)和SPF[(1.51±0.67)%1均显著高于同质体[22.0%,(0.34±0.51)%](P均＜0.01),而Apo百分比[(2.08±1.25)%]显著低于同质体组织[(11.99±10.25)%](P＜0.01).结论 DNA倍体异质性是恶性肿瘤的重要生物学特性之一,且与癌细胞其他生物学特性关系十分密切,可作为肿瘤的恶性程度和预后判断的重要指标.

Prognostic significance of argyrophilic nucleolar organizer staining in soft-tissue sarcomas.

The utility of argyrophilic stain for nucleolar organizer region (AgNOR) for estimating proliferative activity and prognosis of soft-tissue sarcomas (STS) was examined. Formalin-fixed and paraffin-embedded sections of 38 cases with STS were used; the reaction product of AgNOR stain was observed as dots mainly in the nucleoli. The mean number of AgNOR dots per nucleus of tumor cells was calculated in 200 cells (AgNOR count). The AgNOR count, ranging from 1.4 to 16.1 (mean, 7.5), showed a good correlation with cellularity (r = 0.483, p less than 0.003) and histologic grade (r = 0.626, p less than 0.00005), but less shown with mitotic counts (r = 0.350, p less than 0.04). The prognosis of cases with AgNOR low-count group (5-year survival rate was 74.6%) was much better than those in high count group (33.3%) (p less than 0.0005). The AgNOR count correlated well with reactivity of tumor cells for Ki-67 staining, which was available only in freshly prepared sections. These findings suggested that the AgNOR staining is a simple and useful method for estimating tumor-cell proliferation and prognosis of patients with STS.     

胆囊肿瘤细胞DNA含量的测定及其意义

应用流式细胞术的方法，对４６例胆囊肿瘤的石蜡包埋组织（其中３６例胆囊癌，１０例胆囊腺瘤），５例正常胆囊组织细胞ＤＮＡ含量、细胞Ｓ期百分比（Ｓ％）、细胞增殖指数（ＰＩ）进行分析。３６例胆囊癌中，ＤＮＡ异倍体率为５８．３％（２１／３６），胆囊腺瘤及正常胆囊组织细胞ＤＮＡ均为二倍体。胆囊癌、胆囊腺瘤细胞的ＰＩ及Ｓ％均高于正常胆囊组织细胞（Ｐ＜０．０１），这表明胆囊癌、胆囊腺瘤细胞增殖活跃，３６例胆囊癌中，有３例为腺瘤癌变，因此胆囊腺瘤组织具有恶性变的潜能。胆囊癌的组织类型、组织学病理分级、Ｎｅｖｉｎ分级与Ｓ％、ＰＩ、ＤＮＡ倍体的性质无关，胆囊癌患者的预后与ＤＮＡ倍体的性质无关。     

胃癌及癌前病变原位DNA含量与核仁组成区嗜银蛋白定量分析的相关性研究

本文用图像分析的方法对正常胃粘膜、轻、中、重度异型增生、管状腺癌及低分化腺癌共30例石蜡切片标本的细胞核仁组成区嗜银蛋白(AgNOR)和细胞核DNA含量进行了定量检测,并进行了两者的相关性研究。结果显示AgNOR颗粒数量及DNA含量均随病变程度加重而增加,AgNOR数量与DNA含量、超二倍体及超四倍体细胞百分数、DNA直方图倍体类型之间有明显的相关性(r=0.8811,0.7288,0.8606,0.8793);提示AgNOR数量与DNA含量的变化对胃癌前病变的判断与研究具有相近的意义。与细胞核DNA含量检测相比,AgNOR计数分析具有染色简便,易于推广的优点,是胃癌及癌前病变研究中一项新的、实用的参考指标。     

DNA flow cytometry and histopathological grading of paraffin-embedded prostate biopsy specimens in a survival study

Methods to disintegrate old paraffin-embedded tissue blocks for the application of DNA flow cytometry open up new possibilities for retrospective studies on the correlation between tumor cell nuclear DNA pattern and prognosis of the neoplastic disease. In the present work we used such a method to study the relationship between DNA ploidy, histopathological grade, and survival for 50 patients with prostate carcinomas diagnosed 1958-1974. Plugs of histologically identified tissue from benign and tumor areas were sampled from paraffin blocks of prostate biopsy specimens by using a 4-mm skin biopsy punch. Thirty-micron sections were cut from each plug for dewaxing and disintegration. The cell suspensions obtained were stained with 4',6-diamidino-2-phenylindole dihydrochloride and analyzed by flow cytometry. In about one-half of the cases where two or more plugs were analyzed we found a heterogeneous tumor cell nuclear DNA pattern. No apparent correlation was found between the histopathological grade and the DNA ploidy. Using Cox's multiple regression analysis, we found a significant correlation between DNA ploidy and survival of these patients (P = 0.043) when we controlled for histopathological grade (Dhom grade), acid phosphatase level, occurrence of metastases, age, year of diagnosis, and type of biopsy. The correlation between DNA ploidy and survival was just above the level of significance (P = 0.059) when Gleason grade was substituted for Dhom grade in the regression model.     

Agyrophilic nucleolar organizer region counts as related to bromodeoxyuridine incorporation scores in ovarian clear cell carcinoma cells]

The value of agyrophilic nucleolar organizer region (AgNOR) stain as potential technique for the estimation of cell kinetics was assessed in this study. The daily AgNOR counts and the scores of the proliferation-associated marker bromodeoxyuridine (BrdU) in a human ovarian carcinoma cell line-OCC1 for 10 days after subculture were determined. The correlation between AgNOR counts and BrdU incorporation scores was highly significant (r = 0.86, P less than 0.01). Therefore AgNOR counts offer a potential tool to provide cytokinetic information.     

用形态测量方法研究卵巢上皮性肿瘤的诊断及预后

背景与目的:形态测量学在肿瘤的病理诊断及预后评估中日渐重要。本文探讨图像分析法在卵巢上皮性肿瘤的诊断及预后中的意义。方法:联合应用图像分析、AgNOR计量分析及DNA含量测定3种形态测量学方法,对110例原发性卵巢上皮性肿瘤的诊断及预后进行研究,选用的参数为核面积(nucleararea,NA)、核周长(nuclearperimeter,NP)和核形状因子(nuclearformfactor,NFF)、DNA含量(DNAcontent,DC)、DNA指数(DNAindex,DI)、G0/G1期细胞百分率(percentageofG0/G1phases,P2c)、高倍体细胞百分率(percentageofDNAmultiploid,P>4c),并于光镜下进行AgNOR计数。结果:(1)良性、交界性及恶性3组卵巢上皮性肿瘤相比较,NA、NP、NFF、DC、DI及AgNOR计数在各组间差异有极显著性意义(P<0.01或P<0.001)。(2)形态测量学结果与预后关系研究表明,卵巢上皮性癌患者生存≥5年及<5年两组病例中,NA、NP、NFF参数两组间差异有显著性或极显著性意义(P<0.05或P<0.01),不同的图像分析结果提示其预后不同。AgNOR计数与上皮性卵巢癌患者的生存时间呈负相关(r=-0.73,P<0.001)。DNA高倍体含量与上皮性卵巢癌患者生存时间亦呈负相关(r=-0.75,P<0.001)。结论:形态测量学可为不同性质的卵巢上皮性肿瘤的诊断和预后提供可靠的客观依据。     

Proliferating cell nuclear antigen and argyrophilic nucleolar organizer regions in patients with thymic disease

We examined argyrophil nuclear organizer regions (AgNOR) and proliferating cell nuclear antigen (PCNA) in 41 patients with surgically-treated thymic disease. AgNOR count and PCNA labeling index (LI) in thymic carcinoma were significantly higher than those in thymoma and thymic hyperplasia. A positive correlation was observed between the PCNA LI and argyrophilic nucleolar organizer region (AgNOR) counts within all thymic disease (r=0.31, P=0.002). The PCNA LI in invasive thymoma was lower than that in non-invasive thymoma. In survival analysis, the cut-off values for the PCNA LI and AgNOR count were chosen to produce two categories with equal numbers of 26 thymoma patients. There were no significant difference in the survival rate between the lower and higher group patients in relation with AgNOR count and PCNA LI. We conclude that combining AgNOR and PCNA may discriminate the biological activity of thymic disease. These staining methods can be performed with ease and, applied in a clinical laboratory on a routine basis to help predict cytological malignancy of thymic disease.
