Monocyte chemoattractant protein-1 (MCP-1) has been demonstrated to play a role in tumor progression. The present study examined the MCP-1 expression of colorectal liver metastases and determined whether MCP-1 is related to tumor progression and is a predictive marker for survival after hepatic resection of colorectal liver metastases. Eighty-seven patients with colorectal liver metastases were...
The aim of this study was to explore the expression and clinical significance of Foxp3 in colorectal tumor cells. An immunohistochemistry assay was used to detect the expression of Foxp3 in 173 cases of colorectal cancer. The relationship between the clinicopathological factors and the prognosis of colorectal cancer was analyzed. The rate of positive Foxp3 expression in tumor cells was 89.7%. T...
The aim of this study was to initiate a survey of human autoantibody responses to a panel of select colorectal tumor-associated antigens identified by previous serological analysis of a cDNA expression library and to subsequently identify multiple serological biomarkers for the detection of colorectal cancer. For screening of autoantibodies against colorectal tumor-associated antigens, sera fro...
BACKGROUND Studies have examined whether tumor expression of PTGS2 (also known as COX-2), an enzyme inhibited by nonsteroidal anti-inflammatory drugs such as aspirin, is associated with prognosis in patients with colorectal cancer. However, results to date have been mixed. METHODS Using terms for PTGS2 and colorectal cancer, the Medline, Embase, and Web of Science databases were systematicall...
aim : the aim of this study was to compare prognostic factors between colon and rectal cancers. background : prognosis of colorectal cancer (crc) may depend on the anatomical site. patients and methods : a total of 1219 patients with crc diagnosis according to the pathology report of rcgld cancer registry, from 1 january 2002 to 1 october 2007, were entered into the study. demographic and clini...
PURPOSE Epithelial-to-mesenchymal transition (EMT) plays a pivotal role in tumor invasion and dissemination. EMT occurs predominantly at the tumor edge where it is induced by cytokines, the extracellular matrix environment, or hypoxia. In the tumor cell, it is further mediated by several transcription factors and microRNAs. The aim of this study was to explore the expression of EMT-associated g...
Surgery is the cornerstone of oncologic therapy with curative intent. However, identification of tumor cells in the resection margins is difficult, resulting in nonradical resections, increased cancer recurrence and subsequent decreased patient survival. Novel imaging techniques that aid in demarcating tumor margins during surgery are needed. Overexpression of carcinoembryonic antigen (CEA) is ...
AIM To examine the usefulness of the histopathological finding of tumor necrosis for stratifying TNM stage IV colorectal cancer in R0 status. PATIENTS AND METHODS We enrolled 98 patients with stage IV colorectal cancer, without residual disease after resection. The extent of necrosis was assessed using published thresholds, the extent was graded as "absent", "moderate" (<30% of tumor area), o...
Colorectal cancer is the third most common cancer worldwide. Survival and prognosis depend on tumor stage upon diagnosis, and in more than 50% of cases, the tumor has already invaded adjacent tissues or metastasis has occurred. Aiming to improve diagnosis, clinical prognosis and treatment of patients with colorectal cancer, several studies have investigated microRNAs as molecular markers of the...
Purpose: Colorectal cancer infiltration by CD16þmyeloid cells correlates with improved prognosis. We addressed mechanistic clues and gene and protein expression of cytokines potentially associated with macrophage polarization. Experimental Design: GM-CSF or M-CSF–stimulated peripheral blood CD14þ cells from healthy donors were cocultured with colorectal cancer cells. Tumor cell proliferation wa...
