Abstract
Curing of colorectal cancer (CRC) occurs at the time of resection but it is not immediately observable. If the cancer is not completely eliminated, the patient will not be cured of cancer and will experience recurrence as the tumor has regrown to a detectable size. The main propose of the present study was to assess the effects of different covariates on the probability of being cured as well as the time-to-recurrence, and time-to-death in CRC patients by using multi-state cure model. The information of 283 patients with CRC, who underwent resection, from 2000 to 2015 in Imam Khomeini Hospital of Hamadan, Iran, were analyzed. The results of multi-state cure model reveal that females and who experience metastasis were more likely to be apparently cured. It has been shown that sex has a significant effect on the time-to-recurrence given patient was in the not cured group. The survival time of patients of the not cured group was affected by the stage of disease. However, the survival of the apparently cured patients were affected by age at diagnosis and metastasis status. The multi-state cure model provided a flexible framework to study the effects of prognostic factors simultaneously on the transition between different states and the probability of being apparently cured of CRC.

NDPKA is not just a metastasis suppressor - be aware of its metastasis-promoting role in neuroblastoma. J Transl Med 2018; 98:219-227. [PMID: 28991262 DOI: 10.1038/labinvest.2017.105] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2017] [Revised: 07/22/2017] [Accepted: 07/24/2017] [Indexed: 12/20/2022] Open
Abstract
NDPK-A, encoded by nm23-H1 (also known as NME1) was the first metastasis suppressor discovered. Much of the attention has been focused on the metastasis-suppressing role of NDPK-A in human tumors, including breast carcinoma and melanoma. However, compelling evidence points to a metastasis-promoting role of NDPK-A in certain tumors such as neuroblastoma and lymphoma. To balance attention on this contrariety of NDPK-A in different cancer types, this review addresses the metastasis-promoting role of NDPK-A in neuroblastoma. Neuroblastoma is an embryonic tumor, arising from neural crest cells that fail to differentiate into the sympathetic nervous system. We summarize and discuss nm23-H1 genetics and the prognosis of neuroblastoma, structural and functional changes associated with the S120G mutation of NDPK-A, as well as the evidence supporting the role of NDPK-A as a metastasis promoter. Also discussed are the NDPK-A relevant molecular determinants of neuroblastoma metastasis, and metastasis-relevant neural crest development. Because of NDPK-A's dichotomous role in tumor metastasis as both a suppressor and a promoter, tumor genome/exome profiles are necessary to identify the molecular drivers of metastasis in the NDPK-A network for developing tumor-specific therapies.

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.

Evaluation of serum nucleoside diphosphate kinase A for the detection of colorectal cancer. Sci Rep 2016; 6:26703.

Abstract
We previously described the over-expression of nucleoside diphosphate kinase A (NDKA) in tumours and serum from colorectal cancer (CRC) patients, suggesting its use as biomarker. In this study we evaluated the diagnostic accuracy of serum NDKA to detect advanced neoplasia (CRC or advanced adenomas). Furthermore, the performance of NDKA was compared with the faecal immunochemical test (FIT). The study population included a case-control cohort and a screening cohort (511 asymptomatic first-degree relatives of CRC patients that underwent a colonoscopy and a FIT). Serum NDKA was elevated in CRC patients in the case-control cohort (p = 0.002). In the screening cohort, NDKA levels were higher for advanced adenomas (p = 0.010) and advanced neoplasia (p = 0.006) compared to no neoplasia. Moreover, elevated NDKA was associated with severe characteristics of adenomas (≥3 lesions, size ≥ 1 cm or villous component). Setting specificity to 85%, NDKA showed a sensitivity of 30.19% and 29.82% for advanced adenomas and advanced neoplasia, respectively. NDKA combined with FIT (100 ng/mL cut-off) detected advanced adenomas and advanced neoplasia with 45.28% and 49.12% sensitivity, with specificity close to 90%. The combination of serum NDKA and FIT can improve the detection of advanced neoplasia, mainly for lesions located on the proximal colon, in asymptomatic individuals with CRC family-risk.

Abstract
The clinical value of a prominent metastasis suppressor, nonmetastatic protein 23 (NM23), remains controversial. In this study, we examined the correlation between NM23 protein levels and the clinicopathologic features of colorectal cancers (CRC), and assessed the overall prognostic value of NM23 for CRC. Embase, PubMed, Web of Science, and other scientific literature databases were exhaustively searched to identify relevant studies published prior to June 31, 2015. The methodological qualities of selected studies were scored based on the critical appraisal skills program (CASP) criteria, as independently assessed by 2 reviewers. NM23 protein levels in tumor tissues of CRC patients were examined in relation to Dukes stage, differentiation grade, T-stage, lymph node metastasis status, and overall survival (OS). STATA software version 12.0 (Stata Corp, College Station, TX) was used for statistical analysis of data pooled from selected studies. Nineteen cohort studies met the inclusion criteria for present study and contained a combined total of 2148 study subjects. Pooled odd ratios (ORs) for NM23 expression revealed that reduced NM23 protein levels in CRC tumor tissues correlated with Dukes stage C and D (OR = 1.89, 95% CI: 1.06-3.39, P = 0.032), poor differentiation grades (OR = 1.41, 95% CI: 1.03-1.94, P = 0.032), and positive lymph node metastasis status (OR = 3.21, 95% CI: 1.95-5.29, P < 0.001). On the other hand, no such correlations were evident with T-stage T3-4 (OR = 1.56, 95% CI: 0.60-4.06, P = 0.367) or OS (OR = 0.79, 95% CI: 0.58-1.08, P = 0.138). Our analysis of pooled data found that NM23 expression is reduced in CRC tissues and low NM23 levels tightly correlate with higher Dukes stages, poorer differentiation grade, and positive lymph node metastases. However, NM23 levels did not influence the OS in CRC patients.

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
Background Clinical characterization of bladder carcinomas is still inadequate using the standard clinico-pathological prognostic markers. We assessed the correlation between nm23-H1, Rb, EGFR and p53 in relation to the clinical outcome of patients with muscle invasive bilharzial bladder cancer (MI-BBC). Methods nm23-H1, Rb, EGFR and p53 expression was assessed in 59 MI-BBC patients using immunohistochemistry and reverse transcription (RT-PCR) and was correlated to the standard clinico-pathological prognostic factors, patient's outcome and the overall survival (OS) rate. Results Overexpression of EGFR and p53 proteins was detected in 66.1% and 35.6%; respectively. Loss of nm23-H1and Rb proteins was detected in 42.4% and 57.6%; respectively. Increased EGFR and loss of nm23-H1 RNA were detected in 61.5% and 36.5%; respectively. There was a statistically significant correlation between p53 and EGFR overexpression (p < 0.0001), nm23 loss (protein and RNA), lymph node status (p < 0.0001); between the incidence of local recurrence and EGFR RNA overexpression (p= 0.003) as well as between the incidence of metastasis and altered Rb expression (p = 0.026), p53 overexpression (p < 0.0001) and mutation (p = 0.04). Advanced disease stage correlated significantly with increased EGFR (protein and RNA) (p = 0.003 & 0.01), reduced nm23-H1 RNA (p = 0.02), altered Rb (p = 0.023), and p53 overexpression (p = 0.004). OS rates correlated significantly, in univariate analysis, with p53 overexpression (p = 0.011), increased EGFR (protein and RNA, p = 0.034&0.031), nm23-H1 RNA loss (p = 0.021) and aberrations of ≥ 2 genes. However, multivariate analysis showed that only high EGFR overexpression, metastatic recurrence, high tumor grade and the combination of ≥ 2 affected markers were independent prognostic factors. Conclusion nm23-H1, EGFR and p53 could be used as prognostic biomarkers in MI-BBC patients. In addition to the standard pathological prognostic factors, a combination of these markers (≥ 2) has synergistic effects in stratifying patients into variable risk groups. The higher is the number of altered biomarkers, the higher will be the risk of disease progression and death.

Abstract
RB1 gene expression has been reported to be upregulated in colorectal carcinomas (CRC) at both the mRNA and protein levels when compared to normal colonic mucosa. However, allelic loss at the genomic level has been detected in CRC with widely differing frequencies ranging from 11.5% to 50%. To determine whether there is indeed a correlation between RB1 allelic imbalance (AI) and expression, a consecutive series of 55 CRC from Singapore patients were analysed by microsatellite analysis, real-time RT-PCR and immunohistochemistry. Microsatellite analysis using 3 RB1 intragenic microsatellite markers and 2 markers flanking RB1 detected AI in 32.7% (18/55) of the cases, in at least 1 locus. The highest AI frequency (22.9%) was observed at the microsatellite marker D13S137 (Cu13), which maps 5 cM distal to RB1. AI was present in both early and late Dukes stages. Real-time RT-PCR revealed that all 40 cases analysed expressed RB1 mRNA, with mRNA overexpression in 37.5% (15/40) and pRB protein expression in 88.2% (30/34) of cases. Notably, a statistically significant correlation was found between AI of RB1 and mRNA overexpression of RB1 (p < 0.001, Fishers exact test). These findings provide evidence that despite AI, RB1 expression is not abrogated. Thus, our data suggests that RB1 may play a role in colorectal tumorigenesis through functional regulation of the transcript and protein rather than through its tumour suppressor role by gene inactivation.

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
Colorectal carcinomas are characterized by multiple genetic aberrations that occur during tumorigenesis. Several tumor suppressor genes associated with colorectal carcinoma have been identified: MCC, APC, p53, nm23-H1, DCC, DPC4. We examined 73 cases of sporadic human colon cancer and corresponding normal tissue samples to evaluate the loss of heterozygosity (LOH) at the APC gene loci. The purpose of this study was also to evaluate whether the LOH at the APC gene is associated with clinicopathological characteristics in sporadic colon cancer. We also investigated presence and the frequency of the most common APC gene mutations and APC E1317Q and I1307K germ-line variants in Croatian colorectal cancer patients. Five markers in all patients were found to be heterozygous and informative for LOH analysis. LOH at the APC locus was detected in 30.1% of tumors were examined. The majority of APC gene LOH was observed in Dukes' B (55.6%) and in the moderately differentiated tumors (42.9%). Only 1309 APC gene mutation was detected in our samples. In one tumor sample, a new sporadic mutation of the APC gene in codon 1374 was detected. APC E1317Q and I1307K germ-line variants were not detected in our population. But APC E1317Q sporadic mutation was found in one tumor sample.

Abstract
AIM: To investigate KAI1 gene expression in the progression of human colonic carcinoma and its clinical significances.
METHODS: KAI1 expression was detected by in situ hybridization and immunohistochemistry in the 4 established cell lines of colorectal carcinoma with different metastatic potentials, and in 80 specimens of colonic carcinoma, 21 colonic carcinoma specimens with lymphatic metastasis and 20 controls of normal colonic mucosa.
RESULTS: The expressions of KAI1 in HT29 and SW480 cell lines were higher than those in LoVo and SW620. The expression of KAI1 gene was significantly higher in colorectal carcinoma compared with normal colonic mucosa and lymphatic metastasis (χ2 = 46.838, P < 0.01). The expression of KAI1 gene had no relationship with histological grade. The KAI1 expressions in Dukes A and B carcinoma were higher at both mRNA and protein levels compared to Dukes C carcinoma (χ2 = 16.061, P < 0.05). The expression of KAI1 in colonic carcinoma specimens with lymphatic metastasis was almost lost. The results of in situ hybridization were in concordance with immunohistochemistry.
CONCLUSION: KAI1 is highly related to the metastasis of colonic carcinoma and may be a useful indicator of metastasis in colonic carcinoma.

Abstract
OBJECTIVE To assess the role of recurrence in prognosis of colon cancer, we investigated several methodologic issues, including application of classic survival analysis and Markov model. STUDY DESIGN AND SETTING The data were recorded by the Registry of Digestive Tumors of Côte d'Or, France, for 874 patients who had been treated by surgery between 1976 and 1984 and followed for up to 11 years. Survival analyses included the Cox proportional hazards model and its two generalizations that allow recurrence to be taken into account as a time-dependent covariate or as a competing outcome. The Markov model was used to analyze simultaneously recurrence and death. RESULTS The competing risks approach is not appropriate because censoring is indisputably informative. The Markov model and the Cox model, with recurrence as a time-dependent covariate, provided similar results, demonstrating the impact of age and gender on recurrence and revealing a reduction in the effect of site and stage on mortality. CONCLUSION A Markov multistate model seems to give new insights about the course of digestive cancer progression and into the role of recurrence in this process.

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
BACKGROUND The stabilization and nuclear translocation of beta-catenin are early events in the majority of sporadic colorectal carcinomas (CRC). beta-catenin up-regulates c-Myc and cyclin D1, which antagonize the association of the cyclin-dependent kinase (Cdk) inhibitor, p27(kip1), with Cdk2, thus allowing cell cycle progression through G1 to S-phase. Lack of p27 is a significant predictor of poor survival in a series of 136 CRC specimens. A combination of molecules in the same pathway may be a better prognostic factor. METHODS The expression of beta-catenin, c-Myc, and cyclin D1 in relation to patients' survival and clinicopathologic parameters in the same series was evaluated by immunohistochemistry. RESULTS Intense nuclear overexpression of beta-catenin, but not a lack of cell membrane or cytoplasmic expression, is a significant predictor of poor survival by both univariate (P = 0.0029) and multivariate analyses (P = 0.004, risk ratio =3.8), suggesting that beta-catenin is retained in the nucleus to function as an oncogene. None of the patients with high nuclear beta-catenin and low p27 expression survived 5 years or more whereas 65% of patients with all other combinations of the two markers survived (P < 0.0001). This combination is also a significant and independent prognostic factor (P = 0.001; risk ratio = 9.7). Overexpression of c-Myc is associated with higher mortality rates, but the expression of cyclin D1 has no prognostic significance. CONCLUSIONS The combined expression of beta-catenin and p27 can stratify patients into markedly different survival groups, possibly via their antagonistic effects on metastasis promotion.

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
The p27 gene product has been shown to have prognostic significance in a range of tumors. Down-regulation of p27 has also been implicated in loss of cell adhesion in tumor cells. Our study aimed to investigate whether p27 expression was significantly correlated with overall survival of colorectal carcinoma patients in the Singapore population, which is predominantly Chinese. Staining was performed on 136 paraffin-embedded specimens collected between 1991 and 1992 using an anti-p27 monoclonal antibody. Follow-up of patients was until time of death or for 5 years. There was a significant association between overall survival and p27 expression for all specimens. However, there was no significant correlation between p27 expression and other clinical features such as gender, age, tumor stage, differentiation, and site. When stratified by tumor stage, patients whose tumors exhibited higher metastatic potential (stage III/IV) but had strong p27 expression had a median survival that was 23 months longer than stage III/IV patients whose tumors had no or weak p27 expression. Our results thus suggest that one potential mechanism of action of p27 is to suppress metastasis possibly through its involvement in cell adhesion.

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.
