To investigate on expressions and clinical significances of CD133 protein and vasculogenic mimicry (VM) in primary non-small cell lung cancer (NSCLC). The specimens of NSCLC from 305 Chinese patients with follow-up were analyzed for CD133 protein expression and VM by immunohistochemical and histochemical staining. In NSCLC, positive rates of 48.9% and 35.7%(More)
BACKGROUND Breast cancer is the leading cause of cancer death in females worldwide, and the majority type is infiltrating ductal carcinoma (IDC). Most of IDC patients died of metastasis and recurrence. Cancer stem cells (CSCs) are defined with the ability to be self-renewal and potentially promote proliferation and formation of tumors. CSCs are related to(More)
OBJECTIVE To investigate the presence of cancer stem cells (CSCs) exist in non-small cell lung cancer (NSCLC) and explore the relationship among the expressions of CD133, Notch1, and vascular endothelial growth factor (VEGF) and their relations with the clinicopathological parameters of the patients. METHODS A total of 305 specimens of NSCLC and 80 normal(More)
Centrally necrotizing carcinoma of the breast (CNC) represents a newly-identified subset of breast cancer. The clinical and pathological characteristics of this breast cancer subtype are not yet completely understood. We assessed the clinicopathological characteristics of 73 cases of CNC and 30 control cases of high-grade infiltrating ductal carcinoma (IDC)(More)
BACKGROUND AND OBJECTIVE Vasculogenic mimicry (VM), found in many high invasive ability tumors, is associated with tumor invasion and metastasis. Many genes exhibit abnormal levels of expression in these tumors. This study aims to find good markers for predicting the invasion and metastasis of non-small cell lung cancer (NSCLC). METHODS VM and expression(More)
BACKGROUND AND OBJECTIVE In recent years, many studies have revealed the prognosis in patients with non-small cell lung cancer (NSCLC). In general, some clinic-pathological parameters have been related with prognosis. The aim of this study is to detect the relationship among lymphatic vessel density (LVD), microvessel density (MVD), expression of(More)
Esophageal squamous cell carcinoma (ESCC) is a predominant type of esophageal cancer, which is a malignant tumor originating from the esophageal mucosa or gland and is aggressive with poor prognosis. Identification of new gene expression patterns would be helpful for providing new targets for the early detection and treatment of ESCC patients. In the(More)
OBJECTIVE To investigate the antineoplastic effects of 2-Deoxy-D-glucose (2-DG) combined with Taxol on orthotopically transplanted breast cancer in C3H mice and explore the mechanism. METHODS C3H mice bearing orthotopically transplanted breast cancer xenograft were randomly divided into 4 groups, namely the control group, 2-DG group, Taxol group, and(More)
The aim of this study was to investigate KAI1/CD82 protein expression in human nasopharyngeal carcinoma (NPC) cell lines and human NPC tissues. Immunohistochemistry and western blot analysis were used to detect the localization and expression levels of the KAI1/CD82 protein in five human NPC cell lines. Immunohistochemistry was also conducted to detect the(More)
The present paper aims to investigate whether or not vasculogenic mimicry (VM) exists in laryngeal squamous cell carcinoma (LSCC), and to elucidate its relationship to microvessel density (MVD), galectin-3 (Gal-3) expression, and clinicopathological factors of patients with LSCC. VM, score of MVD and expression of Gal-3 protein were detected by(More)
