J Oral Pathol Med (2012) 41 : 124–130 Background: Loco‐regional spread of disease causes high morbidity and is associated with the poor prognosis of malignant oral tumors. Better understanding of mechanisms underlying the establishment of lymph node metastasis is necessary for the development of more effective therapies for patients with oral cancer. The aims of this work were to evaluate a possible correlation between endothelial cell Bcl‐2 and lymph node metastasis in patients with oral squamous cell carcinoma (OSCC), and to study signaling pathways that regulate Bcl‐2 expression in lymphatic endothelial cells. Methods: Endothelial cells were selectively retrieved from paraffin‐embedded tissue sections of primary human OSCC from patients with or without lymph node metastasis by laser capture microdissection. RT‐PCR was used to evaluate Bcl‐2 expression in tumor‐associated endothelial cells and in tumor cells. In vitro, mechanistic studies were performed to examine the effect of vascular endothelial growth factor (VEGF)‐C on the expression of Bcl‐2 in primary human lymphatic endothelial cells. Results: We observed that Bcl‐2 expression is upregulated in the endothelial cells of human oral tumors with lymph node metastasis as compared to endothelial cells from stage‐matched tumors without metastasis. VEGF‐C induced Bcl‐2 expression in lymphatic endothelial cells via VEGFR‐3 and PI3k/Akt signaling. Notably, OSCC cells express VEGF‐C and induce Bcl‐2 in lymphatic endothelial cells. Conclusions: Collectively, this work unveiled a mechanism for the induction of Bcl‐2 in lymphatic endothelial cells and suggested that endothelial cell Bcl‐2 contributes to lymph node metastasis in patients with oral squamous cell carcinoma. 相似文献

Purpose
Lymph node ratio (LNR) essentially improves assessment of prognosis and therapeutic decision making for patients with oral squamous cell carcinoma, as it considers both the number of positive lymph nodes and the number of dissected lymph nodes. Mandibular infiltration by oral squamous cell carcinoma is a vital clinicopathological feature, significantly worsens prognosis. However, to the best of our knowledge, data on the influence of LNR on prognosis for patients with OSCC and mandibular infiltration are not available.Materials and methods
A retrospective chart review of 89 patients with treatment-naive oral squamous cell carcinoma and histopathologically proven mandibular infiltration (pT4a) was performed. Exclusion criteria were primarily curative intended surgery (radical tumor resection, neck dissection and segmental mandibulectomy) with negative resection margins. Exclusion criteria were neoadjuvant chemoradiotherapy, erosive infiltration of the mandible, T4b classification, perioperative death, unresectable disease, synchronous malignancy, follow-up <3 months, and inadequate information to correctly determine clinicopathological characteristics.Results
We observed a significant correlation on univariate analysis between locoregional recurrence and pathologic N classification (p = 0.004), perineural invasion (p = 0.005) and lymph node ratio (p < 0.001). On multivariate analysis, lymph node ratio (p = 0.028) was shown to be an independent indicator for locoregional recurrence.Conclusion
LNR predicted locoregional recurrence better than the conventional nodal staging system and therefore might serve as a more precise risk stratification tool. LNR >7% led to a 11.419-fold higher risk for locoregional recurrence of patients with mandibular infiltration due to OSCC. 相似文献17.

PURPOSE: The ability of oral squamous cell carcinoma to metastasize to lymph nodes does not always show a relationship with clinical staging. The aim of this study was to attempt to define a trend for predictive histopathologic and/or molecular biomarkers in the development of nodal metastasis by analyzing 2 clinically extreme groups. PATIENTS AND METHODS: Patients with small primary tumors (T1, T2) with lymph node metastasis and patients with large primary tumors (T3, T4) without metastatic disease were identified among 315 consecutive cases of primary oral squamous cell carcinoma. Group comparisons were made with use of a Mann-Whitney test, and associations among the variables were assessed with nonparametric and parametric correlational analyses. RESULTS: The degree of keratinization was significantly less in primary tumors with lymph node metastasis (P < or = .01). The degree of keratinization was significantly associated with nuclear pleomorphism (P =.02), number of mitoses (P =.02), stage of invasion (P =.002), and p53 expression (P =.04), independent of clinical stage of the tumor. Other microscopic features and immunohistochemical markers did not differ significantly between the groups (P >.05). CONCLUSION: These data indicate that there still is no single predictive parameter superior to the degree of keratinization to identify patients at risk for the development of regional metastasis. 相似文献

目的 探讨口腔鳞状细胞癌颈淋巴转移的规律及相关临床病理学因素。方法 对708例行颈淋巴清扫术的口腔鳞状细胞癌患者进行回顾性研究,通过单因素和多因素回归分析,寻找影响口腔鳞状细胞癌颈淋巴转移的相关临床病理学因素。采用SPSS19.0软件包对数据进行统计学分析。结果 口腔鳞状细胞癌的颈淋巴转移率为35.6%(252/708),各区的转移率分别为Ⅰ区30.7%(149/485), Ⅱ区33.8%(164/485),Ⅲ区22.5%(109/485),Ⅳ区8.0%(39/485),Ⅴ区4.9%(24/485)。在单因素分析中,年龄、肿瘤分化程度、肿瘤浸润深度、pT分级均与口腔鳞状细胞癌颈淋巴转移显著相关(P<0.05),而性别、原发灶部位与口腔鳞状细胞癌颈淋巴转移无显著相关性(P>0.05);在多因素分析中,仅肿瘤的分化程度、肿瘤的浸润深度、pT分级与口腔鳞状细胞癌颈淋巴转移有明显相关性(P<0.05),肿瘤浸润深度可能是口腔鳞状细胞癌发生颈淋巴转移的首要影响因素(OR=2.191)。结论 口腔鳞状细胞癌颈淋巴转移与pT分期、肿瘤浸润深度呈正相关,与肿瘤分化程度呈负相关。肿瘤浸润深度可能是口腔鳞状细胞癌颈淋巴转移的首要影响因素。 相似文献

Unlike the levels of anatomical exploration, there is no consensus on the extent of lymph node dissection, or lymph node count (LNC), during selective neck dissection (SND). The aim of this study was to validate the prognostic impact of LNC on survival and to determine an optimal LNC cut-off value for SND. A retrospective investigation identified 78 patients with a diagnosis of oral squamous cell carcinoma (OSCC) who underwent SND (levels I–III or levels I–IV). LNC and clinicopathological variables were analyzed for any association with survival in Cox proportional hazards models. Based on the receiver operating characteristic curve, a cut-off value of 19 lymph nodes was found to predict overall survival (OS) (area under the curve 0.732, sensitivity 67.8%, specificity 75.0%; P = 0.026) and disease-specific survival (DSS) (area under the curve 0.762, sensitivity 68.1%, specificity 77.8%; P = 0.011). On Cox regression, LNC (≥19 vs. <19) was the only independent predictor of OS (hazard ratio 5.29, 95% confidence interval 1.39–20.05; P = 0.014) and DSS (hazard ratio 6.76, 95% confidence interval 1.40–32.77; P = 0.018). Similar results were obtained in the pathologically lymph node-negative subgroup (n = 66). Based on the study findings, SND should include 19 or more lymph nodes for a survival benefit. 相似文献
