Plasma fibrinogen levels are correlated with postoperative distant metastasis and prognosis in esophageal squamous cell carcinoma

This study investigated the correlation of preoperative plasma fibrinogen level with distant metastasis and prognosis in esophageal squamous cell carcinoma (ESCC). A total of 255 patients with ESCC who underwent surgery in Zhejiang cancer hospital (Hangzhou, China), between October 2006 and December 2009, were evaluated in this retrospective study. Population controls were selected from a pool of cancer-free subjects in the same region. Each patient and cancer-free people provided 3-mL pretreatment blood. Plasma fibrinogen level was measured by the Clauss method. The effects of hyperfibrinogenemia on locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS), relapse-free survival (RFS), and overall survival (OS) were assessed using Kaplan-Meier analysis. Independent prognostic factors were identified in the multivariate Cox analysis. The proportion of hyperfibrinogenemia was higher in ESCC patients than those in controls (40.4% vs 13.6%). Subjects with hyperfibrinogenemia had a significantly higher risk of ESCC than those with normal plasma fibrinogen level (adjust OR = 4.61; 95% CI = 3.02–7.01, P < 0.001) after adjusted for age, sex and smoking status. The Kaplan-Meier curves showed that patients with hyperfibrinogenemia had worse DMFS, RFS and OS (P < 0.001). Tumor length, lymph node metastasis and plasma fibrinogen level were independent prognostic factors of ESCC (P < 0.05). Increased plasma fibrinogen level was significantly associated with elevated risk of ESCC. Preoperative plasma fibrinogen level was a predictor of distant metastasis and independently associated with prognosis of patients with ESCC.     

Phosphatase of regenerating liver‐3 as a convergent therapeutic target for lymph node metastasis in esophageal squamous cell carcinoma

Phosphatase of regenerating liver‐3 (PRL‐3) is a molecule associated with metastasis in a diverse of cancers, which, however, remains largely unknown in esophageal squamous cell carcinoma (ESCC). We examined both the clinical significance of PRL‐3 expression and its biological roles, and assessed possibilities as a therapeutic target in ESCC. PRL‐3 expression was found in 78% (69 of 88) of the primary ESCC on immunohistochemistry; it was the strong independent predictor for lymph node metastasis (LNM) on a multivariate logistic regression model (p = 0.0014, relative risk =15.20). Additionally, gene amplification was found in 3 (7.9%) of the 38 primary tumors with PRL‐3 overexpression by fluorescence in situ hybridization, but in none of the 19 tumors without it. PRL‐3 small interfering RNA robustly repressed cell proliferation, anchorage‐independent colony formation and invasion and augmented 5‐FU‐induced apoptosis in all the tested ESCC cell lines with PRL‐3 overexpression, irrespective of its gene amplification status. PRL‐3 inhibitor (1‐4‐bromo‐2‐benzylidene rhodanine) also suppressed such metastatic properties in the cell lines with PRL‐3 overexpression, but not with its low expression. Inverse effects were observed by PRL‐3 forced expression. Collectively, PRL‐3 overexpression is a frequent event associated with LNM and plays a causative role in promoting cancer progression. Moreover, the expression status may be a landmark to select patients with benefit from PRL‐3‐targeted therapy. Thus, PRL‐3 could be a convergent therapeutic target against ESCC with LNM.

目的 食管鳞癌两野术后有阳性淋巴结转移者复发率很高,回顾分析食管鳞癌术后淋巴结转移者,采用术后淋巴结转移区域预测术后复发的价值。方法 收集329例胸段食管鳞癌两野R0术后淋巴结转移患者资料,术后淋巴结转移区域位于上腹部、纵隔、纵隔+上腹部者分别为116、119、94例。计数资料行χ²检验,Logistic多因素回归分析评价影响术后复发因素;累积复发率采用Kaplan-Meier法计算和Logrank法检验,Cox模型多因素分析。结果 总复发率为72.4%(239/329),总局部区域复发率为58.1%(139/329),其中颈部、纵隔和上腹部复发率分别为14.6%、42.9%和10.0%。多因素回归分析显示术后淋巴结转移区域是影响术后总复发和局部区域复发的因素(P<0.05)。术后淋巴结转移区域位于上腹部、纵隔、纵隔+上腹部者术后总复发率和局部区域复发率分别为57.8%、77.3%、85.1%和44.0%、62.3%、72.3%;术后淋巴结转移区域也是影响术后纵隔和上腹部复发的因素(P<0.05),但不影响颈部复发(P>0.05);术后淋巴结转移区域位于上腹部、纵隔、纵隔和上腹部者,术后纵隔和上腹部复发率分别为27.6%、47.1%、56.4%和12.9%、4.2%、13.8%。结论 食管鳞癌两野术后淋巴结转移者失败原因主要为局部区域复发;术后淋巴结转移区域可以预测术后总复发和局部区域复发,尤其是术后纵隔或上腹部复发,其结果有助于指导术后辅助放疗靶区设计。     

Tumor lymphangiogenesis correlates with lymph node metastasis and clinicopathologic parameters in oral squamous cell carcinoma

BACKGROUND: Lymphatic vessel density (LVD) and microvessel density (MVD) are important parameters for assessing the malignant potential of tumors and patient survival. In this report, the authors defined LVD as the density of D2-40-positive lymphatic vessels and MVD as the density of CD105-positive microvessels per unit area of tissue. It was reported previously that vascular endothelial growth factor C (VEGF-C) is a major modulator of LVD and MVD. The objectives of this study were to clarify the clinical and prognostic significance of both LVD and MVD in oral squamous cell carcinoma (OSCC) and to elucidate the lymphangiogenic and angiogenic activities of VEGF-C in cancer tissues. METHODS: In total, 110 OSCC tissue samples were evaluated for LVD, MVD, and expression of VEGF-C using immunohistochemistry. Correlations among these parameters and clinicopathologic factors were examined. RESULTS: LVD was significantly higher in tumors that had very high expression of VEGF-C compared with tumors that had no/weak expression of VEGF-C. LVD correlated well with lymph node metastasis (P < .001). MVD was correlated significantly with positive lymph node metastasis (P < .001) but not with VEGF-C expression. In contrast, high expression of VEGF-C was correlated significantly with advanced tumor status (P = .041). Survival rates were lower in patients who had higher LVD (P < .001), higher MVD (P = .0028), and strong VEGF-C expression (P = .048). CONCLUSIONS: Lymphangiogenesis predominantly influenced metastasis-free survival. The current results suggested that LVD is a more useful tool than MVD and VEGF-C for deciding on therapeutic strategies in patients with OSCC.
