Fatty acid synthase expression in squamous cell carcinoma of the tongue: clinicopathological findings

Background:  Overexpression of fatty acid synthase (FAS), the cytosolic enzyme responsible for the conversion of dietary carbohydrates to fatty acids, has been reported in several human malignancies and pointed as a potential prognostic marker for some tumors. This study investigated whether FAS immunohistochemical expression is correlated with the clinicopathological characteristics of oral squamous cell carcinoma (OSCC).
Materials and methods:  The clinical features of 102 patients with OSCC of the tongue treated in a single institution were obtained from the medical records and all histopathological diagnoses were reviewed. The expression of FAS was determined by the standard immunoperoxidase technique in formalin-fixed and paraffin-embedded specimens and correlated with the clinicopathological characteristics of the tumors.
Results:  Eighty-one cases (79.41%) were positive for FAS. Microscopic characteristics such as histological grade ( P  < 0.05), lymphatic permeation ( P  < 0.001), perineural infiltration ( P  < 0.05), and nodal metastasis ( P  < 0.02) were associated with FAS status. A significantly lower survival probability for patients with advanced clinical stage (log-rank test, P  < 0.001), lymph nodes metastasis (log-rank test, P  < 0.001), presence of vascular permeation (log-rank test, P  = 0.05), and perineural invasion (log-rank test, P  = 0.01) was observed in the studied samples.
Conclusion:  The expression of FAS in OSCC of the tongue is associated with the microscopic characteristics that determine disease progression and prognosis.

Clinicopathological prognostic factors of oral tongue squamous cell carcinoma: a retrospective study of 202 cases

Although several histopathological parameters and grading systems have been described as predictive of the treatment response and outcome of oral squamous cell carcinoma (OSCC), none is universally accepted. A new scoring system, the histological risk model, was recently described to be a powerful predictive tool for recurrence and overall survival in OSCC. The aim of this study was to verify the predictive role of the histological risk model in a cohort of 202 patients at all stages of oral/mobile tongue squamous cell carcinoma (OTSCC). Demographic and clinical data were collected from the medical records and the tumours were evaluated using the histological risk model. Statistical analyses were performed using the χ² test, the Kaplan–Meier method, and the Cox regression model. The histological risk model showed no statistical correlation with demographic or clinical parameters and did not Predict the outcome of the OTSCC patients. However, multivariate regression analysis revealed a significant correlation of the clinical disease stage with the disease outcome. Despite major efforts to identify new predictive parameters and histological systems, clinical features are still the most reliable prognostic factors for patients with OTSCC.     

Contralateral lymph neck node metastasis of primary squamous cell carcinoma of the tongue: a retrospective analytic study of 203 patients

In primary squamous cell carcinoma (SCC) of the oral cavity, many clinical and histopathological factors have been described as predictive for cervical lymph-node metastasis, but there are no data available on this association for surgical resection of lateral tongue primary SCC. The aim of this study was to analyse factors related to contralateral neck relapse in a series of 203 consecutive patients with SCC of the lateral aspect of the tongue treated by surgery with or without adjuvant radiotherapy. Several clinical features were analyzed. Histological study included pTNM classification, tumour size, surgical margins, extracapsular spread of lymph-node metastasis, perineural infiltration, peritumoral inflammation and bone involvement. The mean duration of follow up for surviving patients was 70.9+/-49.6 months; 47 patients eventually died of the disease and 116 patients are alive with no evidence of recurrence. The mean disease-specific survival time was 149+/-7 months. Twenty (9.8%) patients developed ipsilateral and nine (4.4%) contralateral neck recurrence. The mean period of time from surgery to contralateral neck recurrence was 11.4 months (range 3-27 months). Fourteen of the 20 ipsilateral and 8 of the 9 contralateral neck relapse patients eventually died of the disease. Histopathological grading and peritumoral inflammation were found to be statistically significant (P<0.05). Clinical and pathological lymph neck node status was not found to be associated with the appearance of contralateral lymph neck node relapse. Due to the increased risk of contralateral neck relapse within the first 2 years of surgery, close surveillance is mandatory at this time.     

舌鳞状细胞癌中EphA7的表达及其与患者病理参数和预后的相关分析

目的 检测舌鳞状细胞癌（tongue squamous cell carcinoma, TSCC）中EphA7的表达,分析其表达水平与TSCC患者临床病理参数及预后的相关性。方法 应用免疫组织化学方法检测54例TSCC及配对癌旁正常组织中EphA7的表达水平,结合随访数据,分析EphA7表达水平与肿瘤病理参数、总体及无瘤生存期的关系。下调SCC9细胞系EphA7的表达水平,检测肿瘤细胞的侵袭、转移能力。采用SPSS17.0软件包进行配对资料t检验和生存分析。结果 所有TSCC组织中均发现EphA7阳性表达,EphA7高表达与不伴淋巴结转移（P<0.05）、无血管浸润（P<0.05）、致密基质细胞炎症反应（P<0.01）以及女性（P<0.05）密切相关;与EphA7低表达患者相比,EphA7高表达组表现出更长的总生存期及无瘤生存期（P<0.05）。下调EphA7表达的SCC9细胞侵袭、转移能力显著增高（P<0.05）。结论 EphA7参与肿瘤恶性进程,影响患者预后,有可能作为TSCC潜在的治疗靶点。

IMP3 is a novel biomarker to predict metastasis and prognosis of tongue squamous cell carcinoma

Insulinlike growth factor II mRNA-binding protein 3 (IMP3) is a newly identified mRNA-binding protein that is involved in embryogenesis and carcinogenesis of some malignant tumors. The aim of this study was to investigate the clinicopathologic significance of this protein in tongue squamous cell carcinoma (SCC). The expression of IMP3 in 65 samples of tongue SCC and 27 cases of oral leukoplakia (OL) was evaluated by immunohistochemistry. These expression levels were correlated with clinical and pathologic features as well as death from tongue SCC. Weak immunohistochemical stain for IMP3 was identified in all 19 cases of OL with mild dysplasia, and no immunohistochemical reactivity was found in 8 cases of OL without dysplasia. Positive immunohistochemical stain for IMP3 was identified in 50 cases (77%) of SCC; among them, weak staining was identified in 33 cases (51%) and intermediate staining in 17 cases (26%). To compare the expression of IMP3 in tongue SCC and OL, stronger immunohistochemical reactivity was found in tongue SCC (P < 0.05). Stronger expression of IMP3 was found to be associated with lymphoid metastasis (P < 0.05) and patient poor outcome (median survival time of 40 months in the negative and weak expression group vs 10 months in the intermediate expression group; P < 0.05). This study suggests that the increase in IMP3 expression in tongue leukopathia and SCCs may play a role in the carcinogenesis and tumor metastasis of tongue SCCs. Insulinlike growth factor II mRNA-binding protein 3 could be a novel prognostic indicator for patients with tongue SCCs.     

上颌鳞癌的颈淋巴转移与预后分析

目的：评估上颌鳞癌的颈淋巴转移情况并分析预后,探讨恰当的治疗方式。方法：回顾2002-1～2011-12间南京大学医学院附属口腔医院收治的67例硬腭及上颌牙龈鳞癌患者资料,研究颈淋巴转移和隐匿性转移的发生率及预后情况,分析临床病理因素对颈淋巴转移及预后的影响,然后提出治疗建议。结果：颈淋巴转移及隐匿性转移发生率分别为17．2％（11/64）和9．8％（5/51）。pT 分期和脉管侵犯显著影响颈转移发生率。pT4期患者的隐匿性转移风险较高。单因素与多因素生存分析发现颈淋巴转移显著降低患者的五年预期生存率。结论：上颌鳞癌的颈淋巴转移与 T 分期显著相关。建议对 T4期患者行选择性颈淋巴清扫（END）,而 T1～T3期患者可以选择术后随访观察。     

Aberrant expression of beta- and gamma-catenin is an independent prognostic marker in oral squamous cell carcinoma

Alteration in expression of E-cadherin and catenins is associated with loss of differentiation, acquisition of an invasive phenotype and poor clinical outcome in many types of cancer. To identify molecular prognostic markers, membrane expression levels of E-cadherin, and alpha-, beta- and gamma-catenin in biopsy samples (n=135) of oral squamous cell carcinoma (OSCC) were evaluated immunohistochemically in relation to preoperative tumour-related features, clinical course and prognostic value, and were found to be significantly correlated with an endophytic growth pattern and pathologically proved lymph-node metastasis. Alteration of expression of E-cadherin, and alpha-, beta- and gamma-catenin was also significantly correlated with poor disease-specific 5-year survival (P=0.0096, 0.0434, 0.0005 and 0.0005, respectively). Multivariate Cox proportional hazard regression analysis showed that alteration of beta- and gamma-catenin expression was a significantly independent prognostic parameter for survival (P=0.0112 and 0.0088, respectively), as was the case with endophytic growth pattern and advanced N-category. These results indicate that patients with OSCC and absent or reduced membrane expression of beta- and gamma-catenin should be considered a high-risk group for regional lymph-node metastasis and poor prognosis.     

Maximum standardised uptake value is prognostic in patients with early-stage squamous cell carcinoma of the tongue

The aims of this paper were to evaluate the relation between the preoperative primary tumour maximum standardised uptake value (SUVmax, tSUVmax) and clinicopathological features, including depth of invasion (DOI), recurrence factors, and survival outcomes, and to compare the prognostic value of tSUVmax with that of other factors associated with the recurrence of early-stage oral squamous cell carcinoma (OSCC) of the tongue. We retrospectively analysed data from 155 patients. All patients were treated and regularly monitored at the Changhua Christian Hospital (CCH). Only those who had undergone ¹⁸F-fluorodeoxyglucose positron emission tomography (FDG-PET) in the 14 days before surgery were included. A tSUVmax of >5.2 was found to be the sole strong predictor of a DOI of >4 mm. A tSUVmax of >7.6 was strongly associated with pT2 SCC of the tongue, more aggressive DOI, and perineural invasion. DOI and tSUVmax could be used to predict disease-free survival (DFS) for early-stage SCC of the tongue, and they showed stronger predictive power than the traditional American Joint Committee on Cancer (AJCC) T stage. Therefore tSUVmax could be a prognostic tool for DFS in AJCC early-stage SCC of the tongue.
