Abstract
Background: Squamous cell carcinoma (OSCC) is the commonest oral malignancy.The overall 5 year survival of OSCC has remained at 50%, largely unchanged for 40 years. CSCs are important within the development, invasion, drug resistance, and prediction of carcinomas treatment outcome. ALDH1 and CD44 are commonly used epithelial tumors cancer stem-like cells surface markers. Materials: Our study aimed to judge CD44 and ALDH1 immunohistochemical expressions in 44 cases of OSCC and relates the expression to patients' survival. Results: High CD44 & ALDH1 expressions were significantly expressed in variable histologic grades of OSCCs, large sized carcinomas, presence lymph vascular invasion, presence of nodal and distant metastasis, advanced TNM clinical stage, recurrence and death during follow up period (P ≤ 0.05). Reduced DFS and three years overall survival were significantly recorded in cases with high CD44 expression, and high ALDH1 expression (p < 0.05). CD44 & ALDH1 expressions, histologic grade, tumor size were the independent predictors of DFS and three years OS. Conclusion: CD44 and ALDH1 expressions are valuable prognostic factors in OSCC and could be well considered predictors for patients' 3 years OS and DFS.

Abstract
Purpose There are limited data on expression of epithelial–mesenchymal transition (EMT) markers in patients with colorectal liver metastases (CRLM). The study aim was to evaluate the expression and prognostic significance of E-cadherin (CDH1), fibronectin (FN1) and vimentin (VIM) in patients with CRLM after curative-intent liver resection. Patients and Methods Thirty patients with CRLM managed by curative-intent liver resection were included in this prospective pilot study. Blood samples, colorectal liver metastases and surrounding non-tumor liver tissue were collected. Expression of CDH1, FN1 and VIM was analyzed by quantitative real-time polymerase chain reaction. Expression in CRLM and non-tumor liver tissue was compared, while expression in serum was correlated with CRLM expression. One-year recurrence-free survival was compared between patients with low and high CDH1, FN1 and VIM expression. Results The expression of CDH1 was similar in CRLM and non-tumor liver tissues, while FN1 and VIM expression was significantly lower in metastatic tissue (P=0.003 and pP<0.001, respectively). Serum expression of CDH1 and VIM was detected in 66.7% and 93.3% of patients, respectively, while FN1 was not detected in any of the patients. The correlation of CDH1 and VIM expression between CRLM and serum was not statistically significant. Decreased CDH1 expression in CRLM and decreased VIM expression in serum were associated with early recurrence after surgical treatment of CRLM. Conclusion Lower expression of CDH1 in CRLM and lower serum expression of VIM were found to be associated with early recurrence after liver resection for CRLM.

Abstract
PURPOSE To investigate the clinical relevance of macrophages in liver metastasis of colorectal cancer and their influence on angiogenesis and patient survival. Moreover to evaluate specific blood monocytes as markers of disease recurrence.Experimental design: In a mouse model with spontaneous liver metastasis, the angiogenic characteristics of tumor- and metastasis (MAM)-associated macrophages were evaluated. Macrophages and the vasculature from 130 primary tumor (pTU) and 123 patients with liver metastasis were assessed. In vivo and in human samples, the clinical relevance of macrophage VEGFR1 expression was analyzed. Blood samples from patients (n = 157, 80 pTU and 77 liver metastasis) were analyzed for assessing VEGFR1-positive (VEGFR1+) cells as suitable biomarkers of disease recurrence. RESULTS The number of macrophages positively correlated with vascularization in metastasis. Both in the murine model as well as in primary isolated human cells, a subpopulation of MAMs expressing VEGFR1 were found highly angiogenic. While VEGFR1 expression in pTU patients did not predict prognosis; high percentage of VEGFR1+ cells in liver metastasis was associated with worse patient outcome. Interestingly, VEGFR1+-circulating monocytes in blood samples from patients with liver metastasis not only predicted progression but also site of recurrence. CONCLUSIONS Our findings identify a new subset of proangiogenic VEGFR1+ MAMs in colorectal cancer that support metastatic growth and may become a liquid biomarker to predict disease recurrence in the liver.

Abstract
In Croatia, colorectal cancer mortality rates in males are the third highest in Europe, after Hungary and Slovakia. The results for females rank Croatia in second place after Hungary. According to previous studies, the loss of E-cadherin expression and the higher expression of neural precursor cell-expressed developmentally downregulated 9 (NEDD9) are associated with a worse prognosis. The aim of the present study was to analyze the immunohistochemical expression of NEDD9 and E-cadherin as markers of metastatic potential using a tissue microarray. This retrospective study included 40 previously untreated patients, including 23 males and 17 females with a median age of 64.5 years (range 38–84), with colorectal cancer and synchronous liver metastases that underwent simultaneous colorectal and hepatic resection between January 1st 2006 and December 31st 2013, in the Clinical Hospital Center Sestre Milosrdnice (Zagreb, Croatia). The most frequent tumor stage was T3, while the most frequent nodal stage was N1. Microvascular invasion was present in 37.5% of patients, while perineural invasion was observed in 30% of patients. The immunohistochemical staining index of E-cadherin was highly positive in 87.5% samples of colorectal cancer, 67.7% of lymph nodes and 77.5% of liver metastases. In the primary tumor, highly positive NEDD9 expression was identified in 22.5% of patients. In lymph nodes, it was identified in 35.5% of patients, while in the liver, it was identified in 30% of patients. Significant positive correlations were observed between the percentage of positive lymph nodes and the immunohistochemical staining index of E-cadherin (ρ=0.372; P=0.039) and NEDD9 (ρ=0.451; P=0.011) in lymph nodes. After the conclusion of the study, 55% of the patients succumbed. No significant differences in survival rates were identified regarding the expression of E-cadherin and NEDD9 in the primary tumor, metastatic lymph nodes and liver metastases. Due to the small sample size and the negative results obtained, further research is required to implement these parameters as prognostic factors.

Abstract
Aim To investigate the relationship between the serum levels of CEA, CA19-9, CA24-2, CA72-4, and AFP in patients with gastric cancer (GC) and their clinicopathological characteristics; to analyze the efficacy of these tumor markers in evaluating the prognosis of GC. Methods Overall, 389 patients with GC either located in the gastric cardia (132), the pyloric antrum (112) or the body of the stomach (145) were included in the study. Serum levels of CEA, CA19-9, CA72-4, and AFP were detected with the ECLIA method, while CA24-2 was measured with ELISA. Results First, the serum level of CEA in GC patients with a cardia-located cancer was significantly higher than in patients with pyloric antrum-located cancer (p=0.050). CA72-4 level in patients with GC located in the gastric body was significantly higher than in patients with cardia and pyloric antrum-located cancers (p=0.042 and p=0.039, respectively). Secondly, serum CA19-9 and CA24-2 levels in females with cardia-located GC were significantly higher than those in males with the same type of tumor (p=0.037 and p=0.033, respectively). Additionally, for females with gastric body-located GC the levels of CEA and CA72-4 were significantly higher than those in male patients with the same type of tumor (p=0.047 and p=0.048, respectively). Conversely, in female GC patients with pyloric antrum-located cancer the serum levels of CA19-9 and CA24-2 were significantly lower than those in male patients with the same type of cancer (p=0.013 and p=0.007, respectively). Moreover, CEA, CA19-9, CA24-2, and CA72-4 levels were strongly related to TNM grade and histological anatomy stage, whereas CEA and CA72-4 levels were strongly related to lymph node stage (p=0.000 and p=0.042, respectively). Patients with vascular embolism had higher serum levels of CEA, CA19-9, CA24-2, and CA72-4 compared with patients without vascular embolism (p=0.005, p=0.031, p=0.007, and p=0.014, respectively). In patients with distant metastases and ascites the levels of CEA, CA19-9, and CA24-2 were higher than in patients without these conditions (p=0.003, p=0.001, p=0.001, p=0.016, p= 0.011, and p=0.030, respectively). Serum CEA, CA19-9, and CA24-2 levels showed correlations with tumor invasive depth and growth types (p=0.001, p=0.040, and p=0.035, respectively). Patients with lump and catheter tumor growth types had significantly higher AFP levels than patients with invasion and anabrosis growth types (p=0.034 and p=0.005, respectively). Tumor size was correlated with the preoperative serum levels of CEA, AFP, and CA72-4 (p=0.007, p=0.020, and p=0.008, respectively). Additionally multiple linear regression analysis showed that preoperative levels of CEA and CA72-4 were correlated to TNM stages, CA19-9 and CA24-2 levels were correlated to both gender and distant metastasis, and AFP was correlated only to ascites. During follow-up there were 115 deaths. Median survival time for GC patients with negative preoperative CEA was 18.07 months, and was 10.97 months for patients with preoperative CEA positive levels (p=0.0005). Similarly, the median survival time for GC patients with negative preoperative CA72-4 was 33.60, and was 16.03 months for patients with preoperative CA72-4 positive levels (p=0.0041). Conclusions The preoperative levels of CEA, CA19-9, CA24-2, CA72-4, and AFP were closely related to TNM grade, gender, distant metastasis and ascites. These makers seem to play important roles in predicting recurrence and metastasis, and in evaluating prognosis.

Abstract
Aims and background We designed the present study to observe CD44s and CD44v6 expressions in colorectal cancer and evaluate their clinical value. Methods CD44s and CD44v6 expression in colorectal cancer tissues were examined by an immunohistochemical test. Survival analysis was performed with the Kaplan-Meier method, and the differences between the CD44-positive and -negative groups were evaluated with the logrank test. Results The positive rates of CD44s and CD44v6 were 66.7% and 63.2%, respectively. There were significant associations between CD44s positive expression and Dukes’ stage or tumor differentiation. There were significant associations between CD44v6 positive expression and tumor differentiation, Dukes’ stage and lymph node metastasis. There was a significant difference in the 5-year survival rates between CD44v6-positive and CD44v6-negative groups (52.78% and 80.95%, respectively), but not between CD44s-positive and CD44s-negative groups (55.26% and 78.95%, respectively). Multivariate analysis indicated that CD44v6 positive expression predicts a poor prognosis. Conclusions CD44s and CD44v6 play important roles in the infiltration and metastasis of colorectal cancer. CD44v6 positive expression can be a predictor for a poor prognosis.

Abstract
Metastasis accounts for most cancer-related deaths. The majority of solid cancers, including those of the breast, colorectum, prostate and skin, metastasize at significant levels to the liver due to its hemodynamic as well as tumor permissive microenvironmental properties. As this occurs prior to detection and treatment of the primary tumor, we need to target liver metastases to improve patients' outcomes. Animal models, while proven to be useful in mechanistic studies, do not represent the heterogeneity of human population especially in drug metabolism lack proper human cell-cell interactions, and this gap between animals and humans results in costly and inefficient drug discovery. This underscores the need to accurately model the human liver for disease studies and drug development. Further, the occurrence of liver metastases is influenced by the primary tumor type, sex and race; thus, modeling these specific settings will facilitate the development of personalized/targeted medicine for each specific group. We have adapted such all-human 3D ex vivo hepatic microphysiological system (MPS) (a.k.a. liver-on-a-chip) to investigate human micrometastases. This review focuses on the sources of liver resident cells, especially the iPS cell-derived hepatocytes, and examines some of the advantages and disadvantages of these sources. In addition, this review also examines other potential challenges and limitations in modeling human liver.

Abstract
CD44 standard isoform (CD44s) is a cancer stem cell marker in many tumors, and is one of the CD44 isoforms.CD44v6 has been reported to correlate with tumor progression and poor prognosis in colorectal cancer. However, the relevance of CD44s and CD44v6 to epithelial-mesenchymal transition (EMT) remains unclear. Immunohistochemistry was performed to investigate the clinical importance of CD44s and CD44v6 and their relevance to EMT in 113 patients with stage II/III colorectal cancer treated by curative resection. The relevance of CD44v6 knockdown to the phenotype of colon cancer cells was examined using small interfering RNA (siRNA) specific for CD44v6 in vitro. CD44v6 expression showed a significant inverse correlation with E-cadherin expression (P=0.0007) and a positive correlation with vimentin expression (P=0.0096). A multivariate analysis showed that high CD44v6 expression was an independent poor prognostic factor for disease-free survival (P=0.01, HR=3.05) and overall survival (P=0.025, HR=3.16). The clinical significance and the relevance of CD44s expression to EMT markers was noted to a lesser extent compared to CD44v6 expression. The knockdown of CD44v6 decreased vimentin expression, cell invasion and HGF-induced cell migration, but conferred only a slight effect on E-cadherin expression in colon cancer cells (HCT116 and LoVo). CD44v6 is related to poor outcome of patients with colorectal cancer via upregulation of the mesenchymal phenotype.

Abstract
Background: The purpose of this study was to assess the role of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and 18F-fluorodeoxyglucose positron emission tomography computed tomography (FDG-PET/CT) for evaluation of response to chemotherapy and bevacizumab and for prediction of progression-free survival (PFS) in patients with metastatic colorectal cancer (mCRC) with potentially resectable liver lesions. Methods: A total of 19 mCRC patients were treated with FOLFOX/FOLFIRI and bevacizumab followed by surgery. Dynamic contrast-enhanced magnetic resonance imaging and FDG-PET/CT were performed before treatment and after cycle 5. PET results were quantified by calculating maximum standardised uptake value (SUVmax) whereas area under the enhancement curve (AUC), initial AUC (iAUC) and the endothelial transfer constant (Ktrans) were used to quantify DCE-MRI. Pathological analysis of the resection specimen was performed, including measurement of microvessel density (MVD) and proliferation index. Results: Both AUC and iAUC were significantly decreased following bevacizumab therapy (median change of 22% (P=0.002) and 40% (P=0.001) for AUC and iAUC, respectively). Progression-free survival benefit was shown for patients with >40% reduction in Ktrans (P=0.019). In the group of radiological responders, the median baseline SUVmax was 3.77 (IQR: 2.88–5.60) compared with 7.20 (IQR: 4.67–8.73) in nonresponders (P=0.021). A higher follow-up SUVmax was correlated with worse PFS (P=0.012). Median MVD was 10.9. Progression-free survival was significantly shorter in patients with an MVD greater than 10, compared with patients with lower MVD (10 months compared with 16 months, P=0.016). Conclusion: High relative decrease in Ktrans, low follow-up SUVmax and low MVD are favourable prognostic factors for mCRC patients treated with bevacizumab before surgery.

Abstract
The colonization of the liver by colorectal cancer (CRC) cells is a complicated process which includes many stages, until macrometastases occur. The entrapment of malignant cells within the hepatic sinusoids and their interactions with resident non-parenchymal cells are considered very important for the whole metastatic sequence. In the sinusoids, cell connection and signalling is mediated by multiple cell adhesion molecules, such as the selectins. The three members of the selectin family, E-, P- and L-selectin, in conjunction with sialylated Lewis ligands and CD44 variants, regulate colorectal cell communication and adhesion with platelets, leucocytes, sinusoidal endothelial cells and stellate cells. Their role in CRC liver metastases has been investigated in animal models and human tissue, in vivo and in vitro, in static and shear flow conditions, and their key-function in several molecular pathways has been displayed. Therefore, trials have already commenced aiming to exploit selectins and their ligands in the treatment of benign and malignant diseases. Multiple pharmacological agents have been developed that are being tested for potential therapeutic applications.

Abstract
AIMS To assess systematically the membranous expression of CD44v6 in colorectal cancer by immunohistochemistry to determine its prognostic impact, the differential expression between primary and metastatic tumours and expression differences between the tumour centre and invasive front. METHODS AND RESULTS Immunohistochemistry was performed for CD44v6 on two tissue microarrays. The first included 1279 colorectal tumours with full clinicopathological data. The second consisted of 50 matched primary and metastatic tumours sampled from the tumour centre and the invasive margin. A scoring system was tested by multiple observers. Receiver-operating characteristic curve analysis was used for cut-off point determination. Loss of membranous CD44v6 was associated with pT stage (P = 0.016; sensitivity 85.8%, specificity 20.1%), lymph node metastasis (P = 0.015; sensitivity 52.8%, specificity 55%), an infiltrating tumour margin (P < 0.001; sensitivity 71.4%, specificity 40%) and adverse prognosis (P = 0.011; hazard ratio 0.79, 95% confidence interval 0.7, 0.9), but was not an independent prognostic factor on multivariable analysis. Loss of expression occurred at the invasive front in both primary and metastatic lesions (P < 0.001). CONCLUSIONS This study outlines an approach to help standardize the immunohistochemical evaluation of CD44v6 and similar markers in colorectal cancer and highlights a significant role for loss of membranous CD44v6 expression in colorectal cancer progression and prognosis.

Abstract
BACKGROUND Microvessel count (MVC) has been correlated with patient prognosis in hepatocellular carcinoma. We investigated whether MVC assessed by staining with CD34 antibody was associated with disease-free and overall survival in patients with metastatic liver cancer (MLC). METHODS We examined relationships between MVC and clinicopathologic factors or postoperative outcomes in 139 MLC patients who underwent hepatectomy between 1990 and 2006. CD34 expression was analyzed by the immunohistochemical method. RESULTS MVC was associated with fibrous pseudocapsular formation on histological examination. By means of the modern Japanese classification of liver metastasis, poorer survival was associated with higher score, poorly differentiated adenocarcinoma, higher preoperative carcinoembryonic antigen (CEA) level, fibrous pseudocapsular formation, and smaller surgical margin. Shorter disease-free survival was associated with higher score when the Japanese classification of liver metastasis was used, multiple or bilobar tumor, regional lymph node metastasis in primary colon carcinoma, preoperative CEA level, fibrous pseudocapsular formation, and smaller surgical margin (<5 mm). Higher MVC (>or=406/mm(2)) was associated with decreased disease-free and overall survival by univariate analysis (P = .034 and P = .021, respectively), and higher MVC represented an independently poor prognostic factor in overall survival by Cox multivariate analysis (risk ratio, 2.71; P = .023) in addition to histological differentiation. CONCLUSIONS Tumor MVC seems to be a useful prognostic marker of MLC patient survival.

Abstract
AIM Cancer death in the early period after hepatectomy still occurs in patients with colorectal liver metastasis (CLM). We examined the relationship between clinicopathological parameters and survival periods in 130 CLM patients who underwent hepatectomy. PATIENTS/METHODS Patients were divided into four groups: Group 1 (5-year survivors without tumor relapse), Group 2 (survivors at 2-5 years), Group 3 (cancer death at 2-5 years), and Group 4 (cancer death within 2 years). RESULTS A short surgical margin was frequent in Group 4 compared to Group 1 (31 vs. 78%, P<0.05). Primary node-positive status, absence of fibrous pseudo-capsular formation, higher Clinical Risk Score, and tumor recurrence within 12 months were frequent in Group 4 (P<0.05). Multivariate analysis revealed a short surgical margin (HR; 3.5) and early tumor relapse (HR; 5.9) as independently significant related parameters (P<0.05). CONCLUSIONS Sufficient surgical margins and careful follow-up for early tumor relapse may be important for improving postoperative outcomes for CLM patients.

Abstract
This study was institutional review board approved, with waived patient consent for retrospective analysis of the data. The hepatic perfusion at dynamic contrast material-enhanced magnetic resonance (MR) imaging was commonly described and assessed by using a dual-input one-compartment tracer kinetics model. Although the tracer kinetics in normal liver parenchyma can be described by using a single compartment, functional changes in the tumor microenvironment can result in distinctly different tracer behavior that entails a second tissue compartment. A dual-input two-compartment model is proposed to describe the tracer behavior in hepatic metastases. The authors applied this model to the dynamic MR imaging data obtained in three patients. Perfusion parameter maps and region-of-interest analysis revealed that tracer behavior in hepatic metastases-in contrast to that in surrounding normal liver tissue, which effectively involves one compartment-can be described by using two compartments.

Abstract
Liver metastasis is a major cause of poor survival of colorectal cancer patients. In order to identify the proteins associated with liver metastasis in colorectal cancer, we carried out two-dimensional gel electrophoresis-based comparative proteomic analysis of normal colon mucosa, primary colon cancer tissue and corresponding metastatic tumor tissue in liver. The proteins identified were further validated by immunohistochemical analysis of 67 quadruplet samples of normal colon primary colorectal cancer and normal liver-synchronous liver metastasis, and 251 colorectal cancers as well as in vitro invasion assay of the human colon cancer cell line, SNU-81. From proteomic assessment, the mitochondrial FoF1-ATP synthase (ATP synthase) alpha-subunit was identified as a protein that is upregulated in liver metastasis compared with the primary tumor. Immunohistochemical analyses confirmed a significant increase in the expression of ATP synthase alpha- and d-subunits in synchronous liver metastasis compared with primary tumor and normal mucosa, respectively. ATP synthase alpha- and d-subunits were overexpressed in 197 (78.5%) and 190 (75.7%), respectively, of the 251 colorectal cancers. The alpha- and d-subunits were significantly associated with liver metastasis (P < 0.05) as well as low histological grade (P < 0.0001). The d-subunit also correlated with venous invasion (P = 0.026) and distant metastasis (P = 0.032). In stage III cancers, d-subunit expression was independently associated with poor survival (P = 0.017). Furthermore, transfection of small interfering RNA targeted to ATP synthase alpha- and d-subunits resulted in decreased in vitro invasiveness of the human colon cancer cell line. Our overall findings demonstrate that increased ATP synthase is associated with liver metastasis of colorectal cancer.

Abstract
It has been suggested that the serum tumor markers AFP, CEA, and CA19-9 may serve as prognostic factors or indicators for recurrence after radical gastrectomy for gastric cancer. We compared the value of these markers in a group with (n=52) and a group without recurrent gastric cancer (n=52) according to the site of recurrence. Serum levels of tumor markers were measured at the time of preoperative diagnosis and at follow-up. At least one tumor marker was positive preoperatively in 20 with recurrence vs. 7 controls (p=0.007). The peritoneum was the most common recurrent site. The positive predictive value of AFP was high at the time of diagnosis and CA19-9 positivity was high at the time of recurrence. Positive CEA suggested recurrence to the liver. In summary, an elevated tumor marker at diagnosis or during follow up may identify patients at higher risk for a recurrence. CA19-9 may be especially useful as a marker for peritoneal recurrence of the gastric cancer, and CEA for recurrence to liver.

Abstract
BACKGROUND Determination of prognosis in patients with resectable colorectal liver metastases (CLM) is desirable in order to improve case selection for surgery and tailor adjuvant treatment according to individual recurrence risk. Conventional clinicopathological factors lack the sensitivity to accurately achieve this goal. Consideration of tumour biology and the identification of molecular prognostic markers may allow more accurate risk stratification. METHOD This systematic review examines evidence from published manuscripts looking at molecular markers in resectable colorectal liver metastases and their correlation with disease recurrence and survival following hepatectomy. RESULTS Studies have yielded promising results in the search for prognostic molecular markers of CLM. Molecular biomarkers from varied aspects of tumour biology have been examined and a number of these, including proliferation indices, telomerase, thymidylate synthase, microvessel density and thrombospondin-1 appear to have prognostic utility in this context. Validation of other markers, notably p53, has been limited by a failure of methodologies to account for their biological complexity. CONCLUSIONS A biomarker-based approach may yield significant benefits through informed treatment of resectable metastatic colorectal malignancy. Standardised retrospective analyses are necessary to confirm preliminary findings and identify existing and novel markers for inclusion into prospective studies. Assessment and verification of multiple molecular markers in this manner may allow molecular profiling of metastases and tailoring of therapy according to the biological aggressiveness of individual tumours. The advent of genomic- and proteomic-based technologies will allow the simultaneous analysis of multiple molecular markers and the derivation of disease profiles associated with disease recurrence and poor survival.

Abstract
Metastatic growth is a selective, non-random process, which in the case of colorectal cancer, frequently occurs in the liver and is the major cause of cancer related death in these patients. This review summarises attempts to find biological and molecular markers of metastasis and their role in establishment of secondary tumours. Recent evidence suggests that liver metastases are phenotypically different to the primary from which they were derived and thus represent a separate disease entity.

Abstract
Immunohistochemical analysis of the expression of E-cadherin, beta-catenin, and CD-44v6 proteins was carried out for evaluating the metastatic potential of colorectal cancer cells. Specific features of expression, distribution, and interactions of adhesive molecules in primary tumors of the large intestine and their metastases in the liver and lymph nodes were studied. Reduction and complete absence of E-cadherin expression were much more often observed in patients with colorectal cancer with metastases in the liver than in patients without metastases. Cytoplasmic immunoreactivity and nuclear translocation of beta-catenin were increased in more than 80% cases with colorectal adenocarcinoma with metastases. These changes in the expression of E-cadherin and beta-catenin in tumor cells can be regarded as factors of unfavorable prognosis of colorectal cancer. No significant relationship between expression of CD-44v6 protein and metastatic potential of cancer cells was detected.

Abstract
BACKGROUND CD44s (standard isoform) is a cell adhesion molecule belonging to the family of the hyaluronan-binding proteins. The CD44 family has been found to be overexpressed in epithelial tumors, where they are generally in relationship with tumor growth and metastasic properties. The aim of this work was to evaluate the membranous CD44s content in colorectal cancer and in healthy surrounding mucosa, its possible relationship with clinicopathological parameters, and its potential prognostic significance. MATERIALS AND METHODS Membranous CD44s levels were measured by an immunoenzymatic assay in tumors and surrounding mucosa samples from 72 patients with resectable colorectal carcinomas. The patients were followed for a mean time period of 30 months. RESULTS There was a wide variability of CD44s levels in tumor-surrounding mucosal samples (26.6-727 ng/mg protein) as well as in tumors (28.5-381 ng/mg protein). Tumor samples showed significantly higher CD44s levels (median: 99.1 ng/mg protein) than surrounding mucosal samples (81 ng/mg protein) (p=0.03). In the same way, CD44s levels in tumors as well as in surrounding mucosal samples were significantly higher in high S-phase tumors than in low S-phase tumors (p=0.001 for both). There was no significant relationship between tumor CD44s levels and patient's outcome. However, high levels of the glycoprotein in nonneoplastic surrounding mucosa were significantly (p=0.018) associated with a poor overall patient survival. CONCLUSION CD44s may play a role in the tumorogenesis of colorectal carcinomas. In addition, CD44s levels in tumor-surrounding mucosa may provide, in concert with some clinicopathological parameters, important information about prognostic evaluation of patients with resectable colorectal carcinomas.

Abstract
PURPOSE This study was conducted to evaluate the prognostic significance of CD44v5 and CD44v6 in resectable colorectal cancer. MATERIALS AND METHODS Membranous CD44v5 and CD44v6 levels were measured by an immunoenzymatic assay in tumors and surrounding mucosal samples obtained from 105 patients with resectable colorectal carcinomas. RESULTS There were no significant differences of CD44v5 levels between tumors [median: 3.2 (range: 0.9-83.5) ng/mg protein) and surrounding mucosal samples (3 (3-146.2) ng/mg protein]. However, tumor samples showed significantly higher CD44v6 levels [19.5 (2.2-562.9) ng/mg protein] than mucosal samples [5 (5-230) ng/mg protein] (P=0.0001). Patients with higher CD44v5 or CD44v6 content in tumor samples had a considerably shorter relapse-free survival (P<0.05, for both). Patients with a higher CD44v6 content also had a shorter relapse-free and overall survival in the multivariate analysis (P<0.05). CONCLUSION The results of this study suggest a role of CD44v5 and CD44v6 in colorectal cancer progression. Membranous CD44v levels in primary tumors, measured by immunoenzymatic assay, may contribute to a more precise prognostic estimation in patients with resectable colorectal cancer.

Abstract
RATIONALE AND OBJECTIVES To apply perfusion computed tomography (CT) technique to variable malignant liver tumors, and to define the usefulness of quantitative color mapping. MATERIALS AND METHODS Perfusion CT images were created for 36 malignant liver tumors in 28 patients (age, 66.4 +/- 10.1 years; range, 48-85) with metastatic liver tumors (n = 17; nine colorectal carcinomas, eight other malignant tumors) and hepatocellular carcinomas (n = 11). A single-slice dynamic CT was performed after an intravenous bolus injection of 40 mL of contrast material (320 mgI/mL) with 8 mL/sec. The parameters were calculated pixel-by-pixel using maximum slope method, and quantitative maps of arterial and portal perfusion were created. In four patients who underwent transcatheter arterial chemoembolization, perfusion CT was performed before and after transcatheter arterial chemoembolization. RESULTS In all patients, liver tumors were shown as hypervascular lesions on arterial perfusion CT. The average arterial perfusion value of the metastatic tumors from the colorectal carcinomas was 0.67 +/- 0.33 mL/min/mL, and that of hepatocellular carcinomas was 0.94 +/- 0.26 mL/min/mL (P = .03). The other metastatic tumors from various primary tumors showed a wide range (0.19-1.45 mL/min/mL) of arterial perfusion. Arterial perfusion of the liver tumors was obviously decreased after successful transcatheter arterial chemoembolization. In 12 of 15 tumors, in which portal perfusion CT images could be created, region-of-interest analysis showed no portal perfusion in the tumors. In two cases, decreased portal perfusion in the segments, which malignant tumors involved, was demonstrated. CONCLUSION Perfusion CT can provide quantitative information about arterial and portal perfusion of liver tumors, combined with good anatomic detail in one image. This technique has a potential to evaluate the angiogenesis of liver tumors, to show secondary changes in perfusion, such as decreased portal perfusion in apparently normal liver adjacent to metastases, and to monitor the therapeutic response in vivo.

Abstract
Carcinoembryonic antigen (CEA) has been suggested as a metastatic activator in colorectal carcinoma, whereas the E-cadherin expression is downregulated in a variety of carcinomas. CEA and E-cadherin expressions were simultaneously assessed with regard to tumor progression in the various sites of colorectal carcinomas with liver metastasis. Twenty-six consecutive patients who had colorectal carcinoma with liver metastasis underwent curative surgery for primary tumor and liver metastasis. CEA and E-cadherin expression were identified on immunohistochemical staining using the labeled streptavidin-biotin method. Their mRNA expression was also detected by RT in situ PCR using one-step reverse transcription-polymerase chain reaction (RT-PCR). CEA and E-cadherin expression scores in the tumor center were greater than those in the tumor margin in both primary tumor and liver metastasis (P<0.001 to 0.006). CEA expression scores were closely associated with E-cadherin expression scores on the corresponding tumor site (P<0.001 to 0.017). CEA and E-cadherin mRNA expression was greatest in the hepatocytes adjacent to liver metastasis, next greatest in the primary tumor, and least in the liver metastasis (P<0.001 to 0.002). CEA mRNA expression was also closely correlated with E-cadherin mRNA expression in the primary tumor (P<0.001) and in the adjacent hepatocytes of the liver metastasis (P=0.018). Patients with a lesser CEA expression score in the liver metastasis margin appeared to have a longer disease-free survival period than did those with a greater CEA expression score. Expression of CEA and E-cadherin was closely correlated with the mRNA levels. Furthermore, these correlations may be implicated in the tumor progression of colorectal carcinoma considering their biological properties.

Abstract
AIM To explore CD44v6 expression and DNA content and the ir significance in the progress of rectal cancer.
METHODS In 40 cases of rectal cancer and 10 cases of normal intestinal tissues, CD44v6 expression and DNA content were detected simultaneously by flow cytometry.
RESULTS The CD44v6 expression and DNA content in rectal cancer were significantly higher than those in normal tissue (70% vs 0%, 1.11±0.6 vs 0.9±0.65, P <0.01). The positive expression of CD44v6 was closely related to the depth of invasion (0% vs 50% vs 80% vs 100%, P <0.05) lymphnode metastasis (93.3% vs 56.0%, P <0.05) and Dukes stage (56.0% vs 93.3%, P <0.05). The DNA aneuploidy in cancer was also related to lymph node metastasis (100% vs 68%, P <0.05) and Duke's stage (68% vs 100%, P <0.05). The expression of CD44v6 did not show any correlation with DNA ploidy of tumor cells (85.7% vs 68.7%, P >0.05).
CONCLUSION The abnormal expression of CD44v6 and DNA aneuploidy plays an important role in the development, invasion and metastasis of rectal cancer. The detection of CD44v6 and DNA content simultaneously may serve as a useful indicator to predict progress of tumor and lymph node metastasis.

Abstract
RATIONALE AND OBJECTIVES The authors developed software for creating quantitative maps of arterial and portal perfusion in the upper abdominal organs on personal computers. The image quality of these perfusion computed tomographic (CT) images was visually evaluated. MATERIALS AND METHODS In 58 patients (38 men, 20 women; mean age, 63.9 years +/- 11.9; range, 22-85 years) with various diseases of the upper abdomen, 91 single-section dynamic CT studies were obtained. The data were transferred on-line to a personal computer, and quantitative maps of arterial and portal perfusion were created by means of the maximum-slope method. Perfusion CT images were reviewed by a radiologist and a radiation technologist, and image quality was rated according to a four-category scoring system (1 = good quality, 2 = moderate, 3 = poor, 4 = images could not be created). RESULTS Arterial perfusion CT images could be created in 81 (89%) of 91 examinations, and 74 images (81%) were scored as 1 or 2. Portal perfusion CT images could be created in 60 (68%) of 88 examinations, in which a portal trunk was included in the section, and 33 of them (38%) were scored as 1 or 2. Patient motion during dynamic CT sequences resulted in poor image quality in seven arterial and 27 portal perfusion images. CONCLUSION Perfusion CT can combine quantitative perfusion maps with good anatomic detail in one image, although patient movement frequently degrades image quality in portal perfusion CT.
