Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies that results from genes regulation via different pathways. NME/NM23 nucleoside diphosphate kinase 1 (NME1) is generally regarded as a metastasis suppressor, but its function in HCC is largely unknown. In our study, we explored the role of NME1 in HCC. By analyzing the gene expression omnibus (GEO) database, we discovered that NME1 was more highly expressed in HCC tumor tissues than non-HCC liver tissues (P < 0.001), and NME1 was significantly up-regulated in HCC tumor tissues than in adjacent normal tissues (P < 0.001). Then, validated by the enrolled HCC patients and The Cancer Genome Atlas (TCGA) database, NME1 was upregulated in HCC tumor tissues compared with matched adjacent normal tissue (P < 0.05). Besides, NME1 was down-regulated in Stage III/IV HCC patients than Stage I/II HCC patients (P = 0.009). Moreover, Kaplan-Meier analysis showed that HCC patients with high NME1 expression had poor overall survival (P = 0.004) and higher recurrence rate (P < 0.001). Our data revealed that NME1 was a special oncogene, and its expression was significantly associated with the progression and prognosis of HCC. NME1 may be a novel molecular biomarker for the targeted therapy and prognosis of HCC.

[PMID: 28224416 DOI: 10.1007/s11596-017-1686-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 11/16/2016] [Indexed: 01/11/2023]
Abstract
This meta-analysis was carried out to evaluate the relationship between NM23 expression and the prognosis of patients with colorectal cancer. We searched PubMed, EMBASE and Web of Science for relevant articles. The pooled odd ratios (ORs) and corresponding 95%CI were calculated to evaluate the prognostic value of NM23 expression in patients with colorectal cancer, and the association between NM23 expression and clinicopathological factors. In total, 2289 patients were pooled from 24 available studies. The incorporative OR combined by 16 studies with overall survival showed that high NM23 expression was associated with better overall survival (OR=0.67, 95%CI: 0.49-0.93, P=0.02, I 2=56%, Ph=0.004). And a new estimate without heterogeneity was produced when only combining high-quality studies (OR=0.70, 95%CI: 0.56-0.86, P=0.0007, I 2=46%). In disease free survival (DFS), we also obtained a good prognosis (OR=0.30, 95%CI: 0.14-0.68, P=0.004). Although we failed to find any significance in N status (P=0.10), elevated NM23 expression was related to well tumor differentiation (OR=0.60, 95%CI: 0.44-0.820, P=0.001) and Dukes' A&B (OR=0.55, 95%CI: 0.32-0.95, P=0.03). These results indicated that over-expressed NM23 might be an indicator of good prognosis, well tumor differentiation and Dukes' A&B of patients with colorectal cancer, but no significance was found in N status.

Abstract
OBJECTIVE There is a heated debate on whether the prognostic value of NME1 is favorable or unfavorable. Thus, we carried out a meta-analysis to evaluate the relationship between NME1 expression and the prognosis of patients with digestive system neoplasms. METHODS We searched PubMed, EMBASE and Web of Science for relevant articles. The pooled odd ratios (ORs) and corresponding 95%CI were calculated to evaluate the prognostic value of NME1 expression in patients with digestive system neoplasms, and the association between NME1 expression and clinicopathological factors. We also performed subgroup analyses to find out the source of heterogeneity. RESULTS 2904 patients were pooled from 28 available studies in total. Neither the incorporative OR combined by 17 studies with overall survival (OR = 0.65, 95%CI:0.41-1.03, P = 0.07) nor the pooled OR with disease-free survival (OR = 0.75, 95%CI:0.17-3.36, P = 0.71) in statistics showed any significance. Although we couldn't find any significance in TNM stage (OR = 0.78, 95%CI:0.44-1.36, P = 0.38), elevated NME1 expression was related to well tumor differentiation (OR = 0.59, 95%CI:0.47-0.73, P<0.00001), negative N status (OR = 0.54, 95%CI:0.36-0.82, P = 0.003) and Dukes' stage (OR = 0.43, 95%CI:0.24-0.77, P = 0.004). And in the subgroup analyses, we only find the "years" which might be the source of heterogeneity of overall survival in gastric cancer. CONCLUSIONS The results showed that statistically significant association was found between NME1 expression and the tumor differentiation, N status and Dukes' stage of patients with digestive system cancers, while no significance was found in overall survival, disease-free survival and TNM stage. More and further researches should be conducted to reveal the prognostic value of NME1.

Abstract
The cumulative lifetime risk for the development of colorectal cancer in the general population is 6 %. In many cases, early detection by fecal occult blood test is limited regarding sensitivity. Therefore, there is an urgent need for improved diagnostic tests in colorectal cancer. The recent development of high-throughput molecular analytic techniques should allow the rapid evaluation of new diagnostic markers. However, researchers are faced with an overwhelming number of potential markers form numerous colorectal cancer protein expression profiling studies. To address the challenge, we have carried out a comprehensive systematic review of colorectal cancer biomarkers from 13 published studies that compared the protein expression profiles of colorectal cancer and normal tissues. A protein ranking system that considers the number of comparisons in agreement, total sample sizes, average fold-change and direction of differential expression was devised. We observed that some proteins were consistently reported by multiple studies as differentially expressed with a statistically significant frequency (P < 0.05) in cancer versus normal tissues comparison. Our systematic review method identified proteins that were consistently reported as differentially expressed. A review of the top four candidates revealed proteins described previously as having diagnostic value as well as novel candidate biomarkers. These candidates should help to develop a panel of biomarkers with sufficient sensitivity and specificity for the diagnosis of colorectal cancer in a clinical setting.

Abstract
CONTEXT NM23, a metastasis suppressor gene, may be associated with prognosis in patients with colorectal carcinoma. OBJECTIVE To analyze NM23 expression and its association with the presence of lymph node and liver metastases and survival in patients operated on for colorectal carcinoma. METHODS One hundred thirty patients operated on for colorectal carcinoma were investigated. Tissue microarray blocks containing neoplastic tissue and tumor-adjacent non-neoplastic mucosa were obtained and analyzed by immunohistochemical staining using a monoclonal anti-NM23 antibody. Immunohistochemical expression was assessed using a semiquantitative scoring method, counting the percentage of stained cells. The results were compared regarding morphological and histological characteristics of the colorectal carcinoma, presence of lymph node and liver metastases, tumor staging, and patient survival. Statistical analysis was performed using the Mann-Whitney test, the Kruskal-Wallis test and Fisher's exact test. Survival analysis was performed using the Kaplan-Meier method and the log-rank test. RESULTS NM23 expression was higher in colorectal carcinoma tissue than in adjacent non-neoplastic mucosa (P<0.0001). NM23 protein expression did not correlate with degree of cell differentiation (P = 0.57), vascular invasion (P = 0.85), lymphatic invasion (P = 0.41), perineural infiltration (P = 0.46), staging (P = 0.19), lymph node metastases (P = 0.08), or liver metastases (P = 0.59). Disease-free survival showed significant association (P = 0.01) with the intensity of NM23 protein immunohistochemical expression in colorectal carcinoma tissue, whereas overall survival showed no association with NM23 protein expression (P = 0.13). CONCLUSIONS NM23 protein expression was higher in neoplastic colorectal carcinoma tissue than in adjacent non-neoplastic mucosa, showing no correlation with morphological aspects, presence of lymph node or liver metastases, colorectal carcinoma staging, or overall survival. Disease-free survival was higher in patients with increased NM23 expression.

Abstract
In search of novel serological protein biomarkers for human colorectal cancer (CRC), we analyzed CRC tissues using two-dimensional difference in-gel electrophoresis (2D-DIGE) on a narrow range IPG strip (pH 5.5-6.7). By comparing tumor tissues with matched normal tissues in a pairwise manner (n = 6), we identified 34 up-regulated and 17 down-regulated spots with intensity changes greater than 2-fold (Student's t-test, p < 0.05). Expression of both mRNA and protein levels of four proteins, adenosylhomocysteinase, Nm23-H1, S100A8 and S100A9, in CRC tissues was further evaluated by semiquantitative RT-PCR and Western blot analysis. The results revealed that all four proteins were elevated in the tumor tissues. We also confirmed, by immunohistochemistry, that adenosylhomocysteinase and Nm23-H1 were overexpressed in tumor cell cytoplasm and that S100A8 and S100A9 proteins were strongly expressed in tumor infiltrating immune cells. Western blot analysis with fractionated plasma samples showed that S100A8 and S100A9 were significantly increased in the plasma of CRC patients (n = 77) and colorectal adenoma patients (n = 11), compared to healthy controls (n = 21). The area under a receiver operating characteristic (ROC) curve was 0.91 for S100A8 and 0.89 for S100A9, which was superior to the established tumor marker carcinoembryonic antigen with 0.78 for the area under the ROC curve. Some patients with inflammatory diseases such as pancreatitis also showed elevated levels of the proteins. Importantly, in comparison to the control group, both proteins showed a remarkable change at the early stage of cancer. Therefore, we suggest S100A8 and S100A9 as candidates for serological biomarkers in combination with other serum markers that aid CRC diagnosis.

Abstract
Even though liver metastasis accounts for the vast majority of cancer deaths in patients with colorectal cancer (CRC), fundamental questions about the molecular and cellular mechanisms of liver metastasis still remain unanswered. Determination of gene expression profiles by microarray technology has improved our knowledge of CRC molecular pathways. However, defined gene signatures are highly variable among studies. Expression profiles and molecular markers have been specifically linked to liver metastases mechanistic paths in CRC. However, to date, none of the identified signatures or molecular markers has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice. To obtain a genetic signature for liver metastasis in CRC, measures to improve reproducibility, to increase consistency, and to validate results need to be implemented. Alternatives to expression profiling with microarray technology are continuing to be used. In the recent past, many genes codifying for proteins that are directly or indirectly involved in adhesion, invasion, angiogenesis, survival and cell growth have been linked to mechanisms of liver metastases in CRC.

Abstract
It has previously been reported that intratumoral microvessel density (IMD), and the expression of bFGF and nm23-H1 are useful prognostic markers in colorectal cancer (CRC). In this study, a total of 100 CRCs were evaluated histopathologically, and IMD, bFGF and nm23-H1 expression were assessed by immunohistochemistry. IMD of patients increased with grade and stage, and this increase was statistically significant (p<0.05). A significantly higher incidence of high bFGF expression scores was also associated with increasing grade and stage (p<0.05). However, there was no significant difference between the grades in nm23-H1 expression (p=0.234). nm23-H1 expression occurred with lower incidence in stages C1, C2 and D than in stages B1 and B2 (p<0.05). Thus, a negative correlation was found between nm23-H1 expression and stage or lymph node metastasis (LNM) (p<0.05). IMD and bFGF expression were positively correlated with grade, stage, LNM, and lymphovascular invasion. Although positive correlation was found between IMD and bFGF, nm23-H1 expression negatively correlated with both of them. As a result, in clinical practice, increased IMD and bFGF expression and decreased nm23-H1 expression may provide valuable information in characterizing the malignant phenotype.

Abstract
PURPOSE The goal of this study was to identify and validate novel serum markers of human colorectal cancer as potential candidates for noninvasive detection of early colorectal neoplasm. EXPERIMENTAL DESIGN Employing two-dimensional gel electrophoresis and mass spectrometry, we analyzed 16 matched colorectal cancer and adjacent normal tissue samples. Proteins found to be elevated in cancer tissue were further validated by generating antibodies which were used for immunoblotting of tissue samples and for the development of highly sensitive immunoassays for assessment of serum samples. RESULTS In total, 735 different proteins were identified in colon tissue. Strong elevation in colorectal cancer for five proteins was confirmed by immunoblot analysis: transforming growth factor-beta induced protein ig-h3 (betaIG-H3), nicotinamide N-methyltransferase (NNMT), nucleoside diphosphate kinase A (nm23-H1), purine nucleoside phosphorylase (PNPH), and mannose-6-phosphate receptor binding protein 1 (M6P1). Elevated levels of NNMT, which is not predicted to be secreted but is known as a cytoplasmic protein, were found in serum from patients with colorectal cancer. Employing a receiver-operating characteristic curve based on the measurement of 109 patients with colorectal cancer and 317 healthy controls, we obtained an area under the curve of 0.84 for NNMT, which was superior to the established tumor marker carcinoembryogenic antigen with an area under the curve of 0.78. CONCLUSIONS It is proposed that NNMT serum levels may have significance in the early detection and in the management of patients with colorectal cancer.

Abstract
BACKGROUND The discovery that genetic alterations in oncogenes and tumour suppressor genes accompany tumour formation in many human tumours has encouraged the search for genes that promote or suppress tumour spread and metastasis; nm23 is a promising candidate for a metastasis suppressing gene. AIMS To evaluate whether expression of nm23-H1 protein or loss of heterozygosity (LOH) of the nm23-H1 gene is associated with colon cancer progression. MATERIALS/METHODS Paraffin wax embedded tissue sections were analysed immunohistochemically. DNA isolated from normal and tumour tissue was used for LOH analysis using a variable nucleotide tandem repeat (VNTR) marker located in the untranslated 5' region of the nm23-H1 gene. RNA isolated from tumour and normal tissue was used for "real time" RT-PCR. RESULTS Of 102 adenocarcinomas examined, 58.8% stained weakly for nm23-H1 protein. There was a negative correlation between nm23-H1 positivity and tumour histological grade. In VNTR analysis, 70.2% of patients were informative and 27.4% of tumours had nm23-H1 LOH. There was a positive correlation between nm23-H1 LOH and both tumour histological grade and Dukes's stage. Expression of nm23-H1 mRNA was increased in 22 of 30 colon tumours compared with normal tissue. No significant correlation was found between nm23-H1 mRNA expression and histological grade or Dukes's stage of tumours. CONCLUSIONS These findings suggest that nm23-H1 protein expression in early stages may have a role in suppressing metastasis in sporadic colon cancer, whereas at a later stage both reduced nm23-H1 protein expression and LOH of the nm23-H1 gene may play role in colon cancer progression and metastasis.

Abstract
Different diagnostic and prognostic groups of colorectal carcinoma (CRC) have been defined. However, accurate diagnosis and prediction of survival are sometimes difficult. Gene expression profiling might improve these classifications and bring new insights into underlying molecular mechanisms. We profiled 50 cancerous and noncancerous colon tissues using DNA microarrrays consisting of approximately 8000 spotted human cDNA. Global hierarchical clustering was to some extent able to distinguish clinically relevant subgroups, normal versus cancer tissues and metastatic versus nonmetastatic tumours. Supervised analyses improved these segregations by identifying sets of genes that discriminated between normal and tumour tissues, tumours associated or not with lymph node invasion or genetic instability, and tumours from the right or left colon. A similar approach identified a gene set that divided patients with significantly different 5-year survival (100% in one group and 40% in the other group; P=0.005). Discriminator genes were associated with various cellular processes. An immunohistochemical study on 382 tumour and normal samples deposited onto a tissue microarray subsequently validated the upregulation of NM23 in CRC and a downregulation in poor prognosis tumours. These results suggest that microarrays may provide means to improve the classification of CRC, provide new potential targets against carcinogenesis and new diagnostic and/or prognostic markers and therapeutic targets.

Abstract
Metastasis is the manifestation most directly affecting survival for patients with colorectal carcinoma. Identification of high-risk markers for metastases would allow focused selection of patients for adjuvant chemotherapy. Reports of the relationship between the putative metastasis suppressor NM23 and metastasis and/or survival in colorectal cancer patients are conflicting. The purpose of this study was to separately assess expression of NM23-H1 and NM23-H2 in primary colon cancers and determine whether expression was associated with regional nodal disease and/or liver metastases. Four patient cohorts were selected on the basis of histopathological staging at primary surgery (lymph node status/liver metastasis): -/- (n = 46), +/- (n = 47), -/+ (n = 43), and +/+ (n = 46). Primary tumors were evaluated by semiquantitative immunohistochemical analysis of NM23-H1 and NM23-H2. NM23-H2 expression was not related to survival; however, there was a modest survival advantage with low expression of NM23-H1 ( P = 0.027). NM23-H1 expression in the +/+ group was increased compared with the other groups ( P < 0.001). The -/+ group had the lowest expression of NM23-H2 ( P < 0.001). This analysis distinguishes two high-risk groups of colorectal cancer patients. Prior discrepancies regarding the usefulness of NM23 staining may be explained by the need to evaluate both serotypes in addition to standard histopathological analysis to identify specific “at-risk” groups.

Abstract
AIMS Expression of nm23 has been identified as a potential metastatic suppressor. In this study, nm23-H1 expression, clinicopathological parameters and influences on clinical outcomes were investigated in colorectal carcinoma patients. METHODS Immunostaining was performed on 185 colorectal carcinomas using a polyclonal anti-nm23-H1 antibody. RESULTS The nm23-H1 immunoreactivity was weak in 31 (17%), moderate in 48 (26%) and strong in 106 (57%) cases. The well differentiated adenocarcinomas showed significantly strong staining for nm23-H1 compared with the moderately and poorly differentiated adenocarcinomas (chi2 test, P<0.001). Advanced tumour stages were associated with reduced nm23-H1 expression (P<0.001). There was an inverse correlation with angiolymphatic invasion, nodal metastasis and liver metastasis (univariate logistic regression analysis, P<0.001). In univariate analysis, patients with reduced expression of nm23-H1 had significantly shorter overall and disease-free survival than the strong expression group (log-rank test for trend, P=0.002 and P=0.003, respectively). CONCLUSIONS Our results indicated that reduced nm23-H1 expression showed poor prognosis in colorectal carcinomas. As a result, nm23-H1 expression might be a useful marker to predict outcome while planning treatment.

Abstract
AIMS The nm23 gene has been shown to have metastasis suppressing activity and abnormalities of the gene or its expression may be important in tumour progression and dissemination. This study was set out to investigate the possible role of the nm23 in colorectal adenocarcinoma dissemination by examining the level of nm23 protein expression in colorectal carcinoma metastasis in regional lymph nodes and the liver. METHODS Using a monoclonal antibody, NCL-nm23 (Novocastra), immunohistochemical expression of the nm23 protein was examined in cases of metastatic colorectal adenocarcinoma in regional lymph nodes (n=71) and liver (n=36). RESULTS The cases of lymph-node metastasis also had tissues from the primary carcinoma (n=71) and matching normal non-neoplastic mucosal tissues (n=71) from the colon and rectum available for the study. More than half of the cases of primary colorectal carcinoma (43/71; 60%) displayed strong nm23 immunoreactivity, with a similar proportion of the lymph-node metastases (40/71 cases; 56%) having strong nm23 immunostaining. However, only a small minority of the normal controls of non-neoplastic colorectal epithelia (12/71 cases; 17%) had strong nm23 immunoreactivity. The difference in nm23 protein expression between normal colorectal mucosa and primary colorectal carcinoma was statistically significant (P=0.0001; chi-squared test with continuity correction). However, no significant difference in nm23 protein expression was found between primary colorectal carcinoma and lymph-node metastases (P=0.81; chi-squared test with continuity correction). Most of the liver metastases (24/36 cases; 67%) had strong nm23 immunostaining but this finding was not statistically significant when compared with that seen in primary colorectal carcinoma (P=0.62; chi-squared test with continuity correction). In addition, nm23 expression was not found to significantly correlate with 5-year survival of patients with liver metastasis (P=0.86), suggesting that it had no predictive value for overall patient survival. There was also no significant correlation between disease recurrence and nm23 expression (P=0.63). CONCLUSIONS In summary, increased nm23 protein immunoreactivity is seen in the majority of colorectal carcinomas when compared to normal colorectal tissues but no significant difference in nm23 expression was found between primary colorectal carcinoma and metastatic carcinoma in regional lymph nodes or the liver. This study suggests that increased nm23 expression may be important in early colorectal carcinoma but not in later progression and dissemination of the tumour. In conclusion, the role and importance of the nm23 gene in the development of tumour metastasis in colorectal carcinoma is questionable.

Abstract
BACKGROUND AND OBJECTIVES A number of evidence indicate that downregulation of the nm23-H1 gene may be relevant to metastatic progression of many kinds of human cancer. However, its role in colorectal cancers remains controversial. To address the issue, this study was performed to investigate the clinical relevance of nm23-H1 in patients with colorectal cancers. METHODS Immunohistochemical expression of nm23-H1 protein product (NM23-H1) was studied in a total of 146 colorectal cancer patients and compared for its prognostic value at a mean follow-up of 54 months. RESULTS There was no apparent correlation between NM23-H1 expression and clinicopathological indicators, including Dukes category, lymphatic metastasis, distant metastasis, histological grading, and tumor location (P < 0.1, respectively). In addition, determination of NM23-H1 expression status did not provide independent prognostic information compared with conventional pathological staging. CONCLUSIONS The results indicate that nm23-H1 gene does not play an important part in the progression of colorectal carcinogenesis.

Abstract
Previously, we showed that expression of nm23-H1 is associated inversely with sensitivity to cisplatin in human oesophageal squamous cell carcinoma (OSCC). The present study was undertaken to investigate the association of nm23-H1 expression with cisplatin-induced DNA damage in OSCC using antisense nm23-H1 transfectants. YES-2/AS-12, an antisense nm23-H1-transfected OSCC cell line, showed significantly reduced expression of intracellular nm23-H1 protein compared with that in parental YES-2 cells and YES-2/Neo transfectants. Surface expression of nm23-H1 protein was not observed in any of the three cell lines. PCR analysis for DNA damage demonstrated that YES-2/AS-12 cells were more resistant to nuclear and mitochondrial DNA damage by cisplatin than were YES-2/Neo cells. In addition, mitochondrial membrane potentials and DNA fragmentation assays confirmed that YES-2/AS-12 was more resistant than YES-2/Neo to apoptosis induced by cisplatin. In contrast, YES-2/AS-12 was more sensitive to ouabain, a selective inhibitor of Na(+), K(+)-ATPase, than YES-2 and YES-2/Neo. Pre-treatment with ouabain resulted in no differences in cisplatin sensitivity between the three cell lines examined. Intracellular platinum level in YES-2/AS-12 was significantly lower than that in YES-2 and YES-2/Neo following incubation with cisplatin, whereas ouabain pre-treatment resulted in no differences in intracellular platinum accumulations between the three cell lines. Our data support the conclusion that reduced expression of intracellular nm23-H1 in OSCC cells is associated with cisplatin resistance via the prevention of both nuclear and mitochondrial DNA damage and suggest that it may be related to Na(+), K(+)-ATPase activity, which is responsible for intracellular cisplatin accumulation.

Abstract
BACKGROUND AND OBJECTIVES Anatomic extent is not the sole axis of classification of tumors and of tumor patients relevant to treatment planning and estimation of prognosis. This results in the need to demonstrate an improvement in prognostic assessment and choice of therapy achieved by consideration of factors other than TNM. nm23 protein does prevent tumor from metastasizing and may also play a role in the control of growth and development. The purpose of this study was to elucidate the clinical significance of nm23 expression in human anal canal carcinoma and to evaluate its influence on the outcome of patients after surgery or radiochemotherapy. METHODS Twenty-two patients affected by anal canal carcinoma were evaluated. Each section was incubated with monoclonal antibody nm23 NDPK-A. Immunostaining was considered positive when at least 10% of the tumor cells were immunostained. RESULTS nm23 immunoreactivity was detected in 6/22 (27.3%) tumors. No significant association was found between nm23 expression and prognosis. CONCLUSIONS The mechanisms causing enhanced nm23-H1 expression in anal canal carcinoma are unknown. Although the level and expression were not correlated with prognosis, activation of nm23-H1 gene might be a prerequisite for oncogenesis in this type of tumor, while an alternate possibility is the modification of cellular characteristics in relation to proliferation and/or differentiation as a consequence of oncogenesis.

Abstract
OBJECTIVE To evaluate the impact of some molecular markers on lymph node metastases, overall (OS) and disease-free survival (DFS) in rectal cancer. PATIENTS AND METHODS We investigated p27(kip1) , p53, nm23, and vascular endothelial growth factor (VEGF) expression in 109 primary rectal cancer specimens (stage I, n=38; stage II, n=24; stage III, n=20; and stage IV, n=27) from patients operated on between 1990 and 1995 at Clinica Chirurgica II. RESULTS Tumour differentiation (P=0.0469), depth of rectal wall invasion (T status) (P=0.0000), distant metastases (P=0.0000), vascular invasion (P=0.0000), and p27(kip1) expression (P=0.0022) were associated with lymph node metastases (N status). During follow up (median duration 47 months), 48 patients died, and 25 patients (stages I-III) had recurrences. At multivariate analysis, T and N status, and intratumoural necrosis were independent risk factors for OS. The relative risk (RR) of death for patients with lymph node metastases, advanced T status and intratumoural necrosis was 3.3 (P=0.0002), 2.03 (P=0.0127), and 1.47 (P=0.1935), respectively. When analysis included only stage I-III patients, N status and p27(kip1) protein expression were found to be independent risk factors for OS. The RR of death for patients with lymph node metastases and those without p27(kip1) expression was 2.98 (P=0.0251), and 3.57 (P=0.0231), respectively. At multivariate analysis, N status, p27(kip1) expression, and intratumoural necrosis were independent risk factors for DFS. The RR of recurrence for patients with lymph node metastases, intratumoural necrosis and absence of p27(kip1) expression was 6.29 (P=0.0001), 3.04 (P=0.0168), and 3.25 (P=0.0387), respectively. CONCLUSION Absence of p27(kip1) expression is a useful marker of tumour aggressiveness in rectal carcinoma stages I-III, and an independent predictor for OS and DFS.

Abstract
Medulloblastomas (MB) are the most common central nervous system malignancies in children. Numerous publications describe efforts to identify the predictive value of various patterns of MB pathology and immunohistochemistry, but received data appear to be controversial. Seventy-three patients with cerebellar MB were studied retrospectively. Tumor specimens were immunohistochemically examined with antibodies to various tumor-associated antigens. Also, apoptosis detection by the in situ end-labeling method was performed. Survival analysis was made using univariate and multivariate models. Tenascin immunoreactivity and apoptotic index (AI) > or = 1.5% were found to be closely associated with poor prognosis according to an univariate analysis (P = 0.008 and 0.003, respectively). The multivariate Cox proportional hazard model exhibited independent prognostic value for the apoptotic rate only (P = 0.023). Tumors with tenascin expression and AI > or = 1.5% significantly prevailed among MB with metastatic dissemination, whereas expression of c-erbB2 oncoprotein and epidermal growth factor receptor was found to be more typical for cases with local tumor recurrence. We came to the conclusion that tenascin immunoreactivity and AI were useful for individual MB prognosis.

Abstract
Recently, nm23-H1, an anti-metastasis gene, has been reported to correlate with sensitivity to chemotherapeutic agents including cisplatin in human breast and ovarian carcinoma cells. The aim of this study was to evaluate a role for nm23-H1 in responsiveness to cisplatin-based chemotherapy in patients with oesophageal squamous cell carcinoma (OSCC). The expression of nm23-H1 protein was examined immunohistochemically in 32 eligible patients with OSCC who underwent adjuvant chemotherapy with cisplatin, etoposide, and 5-fluorouracil after tumour resection. Fifteen (46.9%) of 32 patients were positive for nm23-H1 staining and 17 (53.1%) were negative. Both disease-free survival and overall survival rates of nm23-H1-negative patients were significantly shorter than in nm23-H1-positive patients (P < 0.01 for both). There was no significant difference in clinicopathologic characteristics between nm23-H1-positive and nm23-H1-negative groups. Multivariate analysis also showed that nm23-H1 expression was the most significant factor for overall survival of OSCC patients included in this study (P = 0.0007). To further study the role of nm23-H1, a human OSCC cell line (YES-2) was transfected with a plasmid containing a fragment of the nm23-H1 cDNA in an antisense orientation. Reduced expression of nm23-H1 protein in the antisense-transfected (AS) clones was found by Western blot analysis as compared to wild-type YES-2 and YES-2/Neo (clone transfected with the neomycin resistance gene alone). MTT (3-(4,5-dimethyl-2-thiazol)-2,5-diphenyl-2H tetrazolium bromide) assay showed that reduced expression of the nm23-H1 protein in AS clones was consistent with the degree of increased resistance to cisplatin but not etoposide or 5-fluorouracil. These data support the conclusion that reduced expression of nm23-H1 may be associated with resistance to cisplatin, suggesting the value of nm23-H1 expression as a prognostic marker for OSCC patients who are to undergo cisplatin-based chemotherapy.

Abstract
The nm23 gene is a potential metastasis suppressor gene originally identified using a murine melanoma cell line. The expression of nm23-H1 protein was examined immunohistochemically in 50 eligible patients with esophageal squamous cell carcinoma (ESCC). The expression was not correlated with other prognostic factors including lymph node metastases; however, overall survival rates of nm23-H1-negative patients were significantly shorter than those of nm23-H1-positive patients (P < 0.05). Furthermore, reduced expression of nm23-H1 was associated with shorter overall survival in patients with involved lymph nodes (P < 0.01), but not in patients without involved lymph nodes. These data support the conclusion that reduced expression of nm23-H1 may be associated with poor prognosis of ESCC patients, suggesting the value of nm23-H1 expression as a prognostic marker for ESCC patients, especially ESCC patients with involved lymph nodes.

Abstract
AIMS/BACKGROUND Decreased expression of nm23, a putative metastasis suppressor gene, has been reported to be related to either intrahepatic metastasis or a poor prognosis in hepatocellular carcinoma (HCC). The aim of this study was to elucidate the true role of nm23-H1 expression in both intrahepatic and distant metastases of HCC. METHODS Thirteen patients with single-nodule HCC, seven patients with HCC having satellite nodules and seven patients with HCCs having extrahepatic metastases were included in this study. The expression of nm23-H1 protein was immunohistochemically examined in both primary and metastatic nodules. RESULTS Ten of 13 single-nodule HCCs were found to overexpress nm23-H1 protein. All main tumors, having satellite nodules, were found to overexpress nm23-H protein, except for two HCCs, which only partially expressed nm23-H1 protein. Regarding the nm23-H1 expression in intrahepatic metastases, most nodules overexpressed the protein. The expression of nm23-H1 was found to be low in only one intrahepatic metastasis specimen, while its primary tumor was also found to show a low expression of nm23-H1 protein. Microscopic portal vein invasion was found in three of the five patients studied, and all cancer cells in portal invasion overexpressed nm23-H1 protein. Nm23-H1 protein was expressed in all distant metastatic tumors and the staining intensity of most metastatic nodules was similar to that of the primary tumors. CONCLUSIONS Our study demonstrated that nm23-H1 expression did not always decrease but instead tended to increase at both intrahepatic and extrahepatic metastatic sites. Based on these findings, nm23-H1 expression is not considered to be a reliable indicator of either intrahepatic or distant metastasis in HCC.

Abstract
The NM23-H1 gene product has been recently identified as a potential metastasis suppressor. Studies on breast carcinomas have shown an inverse correlation between NM23-H1 status and stage of carcinogenesis and overall survival. However, in colorectal cancer, conflicting data have been reported. This study aimed to investigate whether NM23-H1 immunostaining is correlated with tumour stage, overall survival, disease recurrence, tumour differentiation, age and sex in colorectal carcinomas for the Singapore population using chi-square analysis. The staining was performed on 141 paraffin-embedded surgical specimens collected between 1991 and 1992 using a monoclonal anti-NM23-H1 antibody. Follow-up of patients was until time of death or for 5 years. There was a very significant inverse association between tumour staging and NM23-H1 status (P = 0.0004). However, NM23-H1 expression was not significantly correlated to overall 5-year survival, disease recurrence, tumour differentiation, age or sex. Thus, although NM23-H1 may be involved in suppressing metastasis, NM23-H1 immunohistochemistry has no prognostic value in colorectal cancer. This is the first report of a significant inverse association of NM23-H1 status with tumour staging in colorectal cancer which showed no correlation with overall survival or disease recurrence. Our result thus cautions against the practice of equating an inverse relation of genetic markers with tumour staging to survival or disease recurrence.

Abstract
A total of 191 colorectal adenocarcinomas, obtained from consecutive patients with a median follow-up of 6 years, were studied in order to evaluate the possible association of Ki-ras mutations with tumour stage, tumour differentiation and survival time. Resected full-cross tumour samples were screened for Ki-ras mutations in codons 12 and 13 using temporal temperature gradient gel electrophoresis (TTGE). Ki-ras mutations were detected in 62 (32%) of the samples. The most frequent mutation, observed in 21 samples, was from GGT to GAT changing glycine to aspartic acid in codon 12. The study did not show any association between Ki-ras mutations and Dukes' stage or tumour differentiation. Patients with Ki-ras mutations had a marginally shorter survival time (median 50 months) compared with patients without (median 59 months), but the difference was not statistically significant. The results indicate that Ki-ras gene mutations have no relevant prognostic importance in this cohort of colorectal cancer patients.
