Applicability of Preoperative Nuclear Morphometry to Evaluating Risk for Cervical Lymph Node Metastasis in Oral Squamous Cell Carcinoma

Background

We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study, we evaluated the applicability of this morphometric technique to evaluating the risk for cervical lymph node metastasis in oral squamous cell carcinoma.

Methods

A digital image system was used to measure the mean nuclear area, mean nuclear perimeter, nuclear circular rate, ratio of nuclear length to width (aspect ratio), and nuclear area coefficient of variation (NACV). Relationships between these parameters and nodal status were evaluated by t-test and logistic regression analysis.

Results

Eighty-eight cases of squamous cell carcinoma (52 of the tongue, 25 of the gingiva, 4 of the buccal mucosa, and 7 of the mouth floor) were included: 46 with positive node classification and 42 with negative node classification. Nuclear area and perimeter were significantly larger in node-positive cases than in node-negative cases; however, there were no significant differences in circular rate, aspect ratio, or NACV. We derived two risk models based on the results of multivariate analysis: Model 1, which identified age and mean nuclear area and Model 2, which identified age and mean nuclear perimeter. It should be noted that primary tumor site was not associated the pN-positive status. There were no significant differences in pathological nodal status by aspect ratio, NACV, or primary tumor site.

Conclusion

Our method of preoperative nuclear morphometry may contribute valuable information to evaluations of the risk for lymph node metastasis in oral squamous cell carcinoma.     

Mean nuclear volume in ovarian papillary serous cystadenocarcinoma

OBJECTIVE: To measure mean nuclear volume (MNV), estimated by the stereologic intercept method, in ovarian serous carcinomas and to compare that between omentum-positive cases (cases with omental metastasis) and -negative cases. STUDY DESIGN: This retrospective study consisted of 29 cases (stage I and II = 13 cases, and stage IIIb = 16 cases) of ovarian papillary serous cystadenocarcinoma. MNV of all cases (at primary and metastatic sites) was estimated with an image cytometer. The nuclear point intersection method was used to measure nuclear volume. Mean intercepted diameters of at least 50 nuclei were measured. MNV was correlated with histologic grade, International Federation of Gynecology and Obstetrics (FIGO) staging of ovarian malignancy and primary tumor versus metastatic deposits. RESULTS: MNVs estimated in omentum-negative (FIGO stage I and II) and omentum-positive (FIGO stage IIIb) cases were 1,022.48 +/- 608.45 and 2,152 +/- 1,317.51 microns 3 (P = .05, Student t test), respectively. Significant differences in MNV were also observed among the different grades of tumor. However, no significant difference was observed between MNVs of primary and metastatic tumors in omentum-positive cases. CONCLUSION: Estimates of MNV on conventional histopathology sections may provide objective and useful criteria for relatively subjective histopathology grading and staging (FIGO stage I and II vs. IIIb).     

Utility of mean nuclear volume in predicting disease-free survival in locally advanced invasive cervical squamous cell carcinoma

OBJECTIVE: To evaluate mean nuclear volume (MNV) as a prognostic indicator in invasive squamous cell carcinoma of the uterine cervix. STUDY DESIGN: Forty-nine consecutive cases of invasive squamous cell carcinoma of the cervix diagnosed in 1995 were analyzed retrospectively for MNV and correlated with outcome at the end of a 5-year follow-up period. RESULTS: The average MNV among patients with a 5-year disease-free survival (DFS) and patients with disease recurrence within the same period was 1424.11 microm3 and 1401.49 microm3, respectively (P = .984, Mann-Whitney test), indicating a poor relationship between MNV and 5-year DFS. CONCLUSION: Estimation of MNV alone in cases of invasive squamous cell carcinoma of the cervix is not predictive of DFS.     

Mean nuclear volume in cervical intraepithelial neoplasia and carcinoma

OBJECTIVE: To correlate three-dimensional nuclear size (mean nuclear volume) estimated by the stereologic intercept methodfor objective classification of cervical intraepithelial neoplasia (CIN) and carcinoma. STUDY DESIGN: In this retrospective study a total number of 29 CIN cases (8 cases of CIN 1, 10 cases of CIN 2 and 11 cases of CIN 3) and 10 cervical squamous cell carcinoma cases were selected. Mean nuclear volume (MNV) of all cases was measured with an image cytometer (Leica, Cambridge, England) using Quantimet 600 software (Leica). Nuclear point resection method was adopted to measure nuclear volume. Mean intercepted diameter of at least 50 nuclei was measured randomly. MNV was correlated with the histologic grade and diagnosis. RESULTS: MNV of CIN 1, 2, 3 and carcinoma cases was 291.72, 403.33, 711.45 and 893 microm3, respectively. ANOVA test results showed that MNV of CIN 1 and 2 was significantly lower than that of CIN 3 and invasive carcinoma (P < .000). MNV of CIN 3 was also significantly lower than that of carcinoma cases (P <.05). CONCLUSION: The findings suggest that estimates of MNV on conventional histopathology slides provide objective and useful criteria for relatively subjective histopathologic grading.     

Overexpression of phosphatase regenerating liver 3 in oesophageal squamous cell carcinoma associated with metastasis and its comparison with phosphatase regenerating liver 1

Expression of PRL3 (phosphatase of regenerating liver 3) protein was examined with immunohistochemistry in 60 cases of ESCC (oesophageal squamous cell carcinoma) with matched lymph node metastasis (n = 40) and 6 cases of oesophageal adenocarcinoma. Its associations with PRL1 and clinicopathological parameters were analysed. The results showed the frequency of PRL3 protein expression was significantly higher in ESCC (39/60, 65%) than in normal oesophageal mucosa (0/20, P < 0.001); higher in ESCC with lymph node metastasis (30/40, 75%) than in ESCC without lymph node metastasis (9/20, P = 0.022), as well as higher in metastatic ESCC in lymph node (38/40, 95%) than in the primary ESCC (39/60, 65%, P < 0.001). PRL3 was expressed in 1 out of 6 oesophageal adenocarcinomas, but showed no nuclear staining of PRL1. Expression of PRL3 protein was positively associated with the grade and partially with the stage of ESCC. These results suggest that expression of PRL3 protein may be involved in the metastasis of ESCC and serve as a biomarker for prediction of ESCC metastasis.

Expression of Mina53 and its significance in gastric carcinoma

AIM: To study the expression of Mina53 and its relationships with clinicopathological characteristics, antioncogene inactivation and tumor proliferation in human gastric carcinoma, and to explore the role of Mina53 in carcinogenesis and tumor progression. METHODS: Expression of Mina53 and proliferating cell nuclear antigen (PCNA) was determined in gastric carcinoma (n=79), gastric dysplasia (n=21) and normal gastric tissues (n=20), while p53 was measured in gastric carcinoma tissues by immunohistochemistry. RESULTS: Mina53 was negatively expressed in all normal mucosa tissues. Dysplasia specimens showed weakly positive staining for Mina53 in 3 of 21 cases. Elevated expression of Mina53 was observed in 72 (91.1%) of the gastric carcinomas. No significant associations were found between Mina53 and clinicopathological characteristics such as sex, age, histological differentiation, distant metastasis and lymph node metastasis (p>0.05). There was a significant association with depth of invasion (X2=5.385, p<0.05) and TMN stage (X2=6.255, p<0.05). In gastric carcinoma, positive staining for p53 was detected in 53 of 79 cases (67.1%), showing a significant association with Mina53 (X2=5.161, p<0.05). The mean (+/- SD) PCNA labeling index for gastric carcinoma was 39.47+/-16.92%. Mina53 expression was positively associated with PCNA level (r=0.756, p<0.01). CONCLUSION: Mina53 was overexpressed in gastric carcinoma and associated with tumor proliferation and antioncogene inactivation. Mina53 could therefore play an important role in the carcinogenesis and progression of gastric carcinoma.

EGFR在晚期声门上型喉鳞癌组织中的表达及其临床意义

目的:研究表皮生长因子受体(epidermalgrowth factorreceptor,EGFR)在晚期声门上型喉鳞癌组织中的表达情况及其与临床各相关因素的关系,探讨EGFR能否作为判断晚期声门上喉鳞癌患者预后的预测性指标。方法:收集我院2004年1月~2008年4月共52例晚期(Ⅲ期、Ⅳ期)声门上型喉鳞癌患者手术后切除的肿瘤组织,应用免疫组化技术检测EGFR表达情况,运用统计学方法,结合临床资料分析其与肿瘤分期、淋巴结转移、病理分化程度、生存率及术后放疗对预后的影响等临床病理特征的关系。结果:EGFR在晚期声门上型喉鳞癌组织中存在阳性表达,阳性表达物质呈棕黄色,表达率为76.92%(40/52),其中过表达率为44.23%。EGFR的表达与晚期声门上型喉鳞癌患者的年龄、性别、吸烟无关,与浸润程度(P=0.005),淋巴结转移数目(P=0.018),TNM分期(P=0.003),病理分化程度(P=0.011)有关。单因素分析得出EGFR表达程度、T、N分期以及病理分化程度是影响无复发生存时间的危险因素(P0.05),T、N分期、病理分化程度是影响总生存时间的危险因素(P0.05)。多因素分析显示只有肿瘤浸润程度(T分期)和淋巴结转移(N分期)是影响无复发生存时间和总生存时间的独立预后因素。EGFR的阴性表达组与阳性表达组的3年、5年生存率不具有统计学差异(P0.05)。结论:EGFR在晚期声门上型喉鳞癌组织中存在过表达,证实了EGFR的过度表达与肿瘤的侵袭、转移相关,检测其表达水平对晚期喉癌的个体化治疗、靶向治疗有重要参考价值。但EGFR尚不能作为晚期声门上型喉鳞癌行手术及术后辅助放疗患者对无复发生存时间和总生存时间的预测指标。
