Int J Cancer 2024; 154:477-487. [PMID: 37728072 DOI: 10.1002/ijc.34730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/14/2023] [Accepted: 07/21/2023] [Indexed: 09/21/2023]
Abstract
Geographic and sex differences in esophageal cancer have been reported in China, but data are lacking at the local level. We aimed to investigate geographic and sex disparities in esophageal cancer incidence among Chinese counties and whether county-level socioeconomic status was associated with these variations. We obtained esophageal cancer data from 2015 to 2017 for 782 counties from population-based cancer registries in China. We calculated age-standardized incidence rates and male-to-female incidence rate ratios (IRRs) by county. We performed hotspot analysis to identify geographical clusters. We used negative binomial regression models to analyze the association between incidence rates and county-level socioeconomic factors. There were significant geographic disparities in esophageal cancer incidence, with 8.1 times higher rate in the 90th-percentile county than in the 10th-percentile county (23.7 vs 2.9 per 100 000 person-years). Clusters of elevated rates were prominent across north-central China. Nationally, men had 2.9 times higher incidence of esophageal cancer than women. By county, the male-to-female IRRs ranged from 1.1 to 21.1. Clusters of high male-to-female IRRs were observed in northeast China. Rurality (IRR 1.16, 95% CI 1.10-1.22), per capita gross domestic product (IRR 0.95, 0.92-0.98) and percentage of people with a high school diploma (IRR 0.86, 0.84-0.87) in a county were significantly associated with esophageal cancer incidence. The male-to-female IRRs were higher in counties with higher socioeconomic status. Substantial differences in incidence rates and sex ratios of esophageal cancer exist between Chinese counties, and county-level socioeconomic status was associated with these variations. These findings may inform interventions to reduce these disparities.

Abstract
Esophageal cancer (EC) is the ninth most common cancer and the sixth leading cause of cancer deaths worldwide. Esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) are the two main histological subtypes with distinct epidemiological and clinical features. While the global incidence of ESCC is declining, the incidence of EAC is increasing in many countries. Decades of epidemiologic research have identified distinct environmental exposures for ESCC and EAC subtypes. Recent advances in understanding the genomic aspects of EC have advanced our understanding of EC causes and led to using specific genomic alterations in EC tumors as biomarkers for early diagnosis, treatment, and prognosis of this cancer. Nevertheless, the prognosis of EC is still poor, with a five-year survival rate of less than 20%. Currently, there are significant challenges for early detection and secondary prevention for both ESCC and EAC subtypes, but Cytosponge™ is shifting this position for EAC. Primary prevention remains the preferred strategy for reducing the global burden of EC. In this review, we will summarize recent advances, current status, and future prospects of the studies related to epidemiology, time trends, environmental risk factors, prevention, early diagnosis, and treatment for both EC subtypes.

Abstract
BACKGROUND Patients with primary oesophageal squamous cell carcinoma are at risk of developing multiple primary tumours in the upper aero digestive tract. To date, most studies are performed in the Asian population. We aimed to evaluate the risk of multiple primary tumours in the upper aero digestive tract and stomach in patients with oesophageal squamous cell carcinoma in a Western population. METHODS We performed a nationwide, retrospective cohort study in collaboration with the Netherlands Cancer Registry. Patients with primary oesophageal squamous cell carcinoma, diagnosed between 2000 and 2016, were included. Primary endpoints were synchronous and metachronous multiple primary tumour risk. RESULTS The cohort consisted of 9058 patients, diagnosed with oesophageal squamous cell carcinoma (male: 57.3%, median age 67 years). In 476 patients (5.3%), 545 multiple primary tumours have been diagnosed. Most of them were located in the head and neck region (49.5%). Among all multiple primary tumours, 329 (60.4%) were diagnosed synchronously (<6 months after oesophageal squamous cell carcinoma diagnosis) and 216 (39.6%) metachronously (6 months). Patients with oesophageal squamous cell carcinoma had a significantly increased risk of both synchronous (standardised incidence ratio 10.95, 99% confidence interval 9.40-12.53) and metachronous multiple primary tumours (standardised incidence ratio 4.36, 99% confidence interval 3.56-5.10), compared to the general population. The median interval to metachronous second primary tumour diagnosis was 3.0 years (interquartile range 1.8-5.9). CONCLUSION Approximately one in 20 patients with primary oesophageal squamous cell carcinoma have a second primary tumour in the upper aero digestive tract or stomach, either at the time of oesophageal squamous cell carcinoma diagnosis or at a later stage. As second primary tumours occur at an increased risk compared to the general population, prospective studies are necessary to investigate the yield and survival benefit of screening for second primary tumours in patients with oesophageal squamous cell carcinoma.

[PMID: 32750217 PMCID: PMC7520289 DOI: 10.1002/cam4.3338] [Citation(s) in RCA: 61] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 06/28/2020] [Accepted: 07/08/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND The incidence and mortality of esophageal cancer are high, with 5.90 new cases and 5.48 deaths per 100 000 people worldwide in 2017. The prognosis of esophageal cancer is poor, with an overall 5-year survival rate of less than 20%. Esophageal cancer in different geographical locations has different etiologies, and the incidence and mortality of esophageal cancer continue to rise in some regions. METHODS We collected incidence and mortality data by age and gender for 195 countries and territories from 1990 to 2017 in the Global Burden of Disease (GBD) database. And we used these data to calculate the estimated annual percentage change (EAPC) to quantify trends in morbidity and mortality. Then we analyzed the gender- and age-specific incidence and mortality in esophageal cancer to targeted high-risk populations. Finally, we analyzed the correlation between the age-standardized mortality rate (ASMR) and both the EAPC and social-demographic index (SDI), and we calculated the Pearson correlation coefficient. RESULTS We found that Malawi, East Asia, and high-middle SDI regions had the highest age-standardized incidence rate (ASIR) and ASMR, and the ASIR and ASMR in western Sub-Saharan Africa showed an upward trend. Our study also showed that the incidence and mortality in esophageal cancer were highest in men and in the 70+ years age group, and they presented a decreasing trend in most regions, but the 15-49 years age groups in Australasia, Caribbean, and Oceania and the 70+ years age group in High-Income North America, Oceania and high-SDI regions presented an increasing trend. There were significant negative associations between ASMR at baseline and EAPC and between ASMR and SDI in 2017. CONCLUSION By analyzing the global distribution of incidence and mortality in esophageal cancer, trends over time, and gender and age specificity, we can understand the heterogeneity of its global trends. This heterogeneity can help us to identify high-risk groupsand to provide clues for the exploration of the etiology and early prevention of the disease.

Association of cytotoxic T-lymphocyte associated protein 4 gene polymorphisms with the risk and prognosis of oesophageal cancer in a high-incidence region from northern China. Int J Immunogenet 2019; 47:180-187. [PMID: 31883177 DOI: 10.1111/iji.12470] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Revised: 11/29/2019] [Accepted: 12/06/2019] [Indexed: 01/02/2023]
Abstract
The most important anti-tumour immune response is mediated by T lymphocytes. Cytotoxic T lymphocyte-associated protein 4 (CTLA4) plays a critical role in the immune surveillance against tumours as an inhibitory immune checkpoint molecule of T-cell activation. This study was designed to explore the association of CTLA4 polymorphisms with the susceptibility to oesophageal squamous cell carcinoma (ESCC) and prognosis of patients with ESCC in a high-incidence population from northern China. CTLA4 rs5742909 C/T and rs231775 G/A single nucleotide polymorphisms (SNPs) were genotyped using polymerase chain reaction-ligase detection reaction (PCR-LDR) method in 577 ESCC patients and 580 controls. Upper gastrointestinal cancer family history increased the risk of ESCC (the sex-, age- and smoking status-adjusted OR = 1.383, 95%CI = 1.094-1.749). The genotype frequencies of these two SNPs in the patients with ESCC were similar to that in the controls. Survival analyses were conducted in 204 patients with ESCC with five-year survival information. The mean survival time of ESCC patients with rs231775 SNP A/A genotype in age over 60 years group was 23.2 months, significantly shorter than that of those with G/G genotype (47.3 months). The A/A genotype was associated with increased death risk of patients with ESCC older than 60 years (adjusted HR = 4.544, 95%CI = 1.913-10.790). CTLA4 rs231775 SNP might be used as genetic marker of worse prognosis for patients with ESCC over 60 years in a high-incidence population from northern China.

Abstract
The Huai'an area in Jiangsu Province of East China is an endemic region of esophageal cancer (EC). The regional heterogeneity of EC suggests that the levels of potential carcinogens might vary throughout the environment. It has been suggested that the most likely carcinogens related to EC are a group known as the N-nitrosamines. In this study, we measured the concentrations of nine nitrosamines in drinking water and human urine in two areas in China, one with a high incidence of EC (Huai'an) and one with a low incidence (Nanjing). Among the nine target analytes, N-nitrosodi-n-propylamine (NDPA), N-nitrosodibutylamine (NDBA), N-nitrosopyrrolidine (NPyr), N-nitrosodiethylamine (NDEA) and N-nitrosomorpholine (NMor) occurred at higher concentrations in drinking water in the high incidence area. Inhabitants from the high incidence area also had urinary excretions with significantly higher concentrations of NDEA, NDBA, N-nitrosopiperidine (NPip) and N-nitrosodiphenylamine (NDPhA). These findings indicated that people in the high EC incidence area were exposed to higher levels of nitrosamines. However, the association between the incidence of EC and nitrosamines exposure will need to be evaluated in more detail.

Abstract
Background Esophageal squamous cell carcinomas (ESCCs) are often accompanied by head and neck second primary tumors (HNSPTs). The prognosis of patients with an additional HNSPT is worse compared with patients with only ESCC. Therefore, early detection of HNSPTs may improve the overall outcome of patients with ESCC. The purpose of this study was to investigate the yield of endoscopic screening for HNSPTs in patients with primary ESCC. Methods We conducted a systematic literature search of all available databases. Studies were included if ESCC patients were endoscopically screened for HNSPT. The primary outcome was the pooled prevalence of HNSPTs. Results Twelve studies, all performed in Japan, were included in this systematic review with a total of 6483 patients. The pooled prevalence of HNSPTs was 6.7% (95% confidence interval: 4.9–8.4). The overall heterogeneity was high across the studies (I2 = 89.0%, p < 0.001). Most HNSPTs were low stage (85.3%) and located in the hypopharynx (60.3%). The proportion of synchronous (48.2%) and metachronous (51.8%) HNSPTs was comparable. Conclusion Based on our results, HNSPT screening could be considered in patients with primary ESCC. All studies were performed in Japan; it is therefore not clear whether this consideration applies to the Western world.

[PMID: 29559669 PMCID: PMC5861081 DOI: 10.1038/s41598-018-23251-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Accepted: 03/08/2018] [Indexed: 12/16/2022] Open
Abstract
To compare the differences in dietary status and knowledge of esophageal cancer (EC) between residents of high- and low-incidence areas. We investigated dietary conditions and EC knowledge among residents in high- and low-EC incidence areas (Yanting and Qingzhen counties). Residents in Yanting consumed more pickled vegetables, salted meat and barbecued food (P < 0.05). Analysis of the past ten-year trend in Yanting consumed fresh vegetables/fruits, beans, sauerkraut, hot food, and barbecued food had gradually increased, and the trend was less than that in Qingzhen County. However, the gradual increasing trend in consumption of pickled vegetables, pickled meat, and spicy food over the past 10 years was greater (P < 0.05). Drinking water in Yanting County was healthier than that in Qingzhen County (P < 0.05). In terms of EC knowledge, the proportions of residents in Yanting who had a clear understanding, knowledge or had heard of EC or knew the common causes, primary symptoms, therapeutic measures, preventive measures, and government interventions for EC were all higher than in Qingzhen (P < 0.05). Residents in Yanting had greater EC knowledge but more harmful dietary habits than those in Qingzhen.

Abstract
Raf kinase inhibitory protein (RKIP) regulates multiple cellular processes, and its downregulation is associated with distinct human cancers. In the present study, the status of RKIP promoter methylation, as well as its expression and clinical significance in esophageal squamous cell carcinoma (ESCC), were examined. The promoter methylation status in the 5'-CpG island of the RKIP gene and the expression level of the RKIP protein were examined using a modified methylation-specific polymerase chain reaction (MSP) method and immunohistochemical staining, respectively, in 77 ESCC samples and matched paratumor normal tissues. The incidence of RKIP promoter methylation was significantly higher in tumor samples (75.3%) than in the matched normal tissues (27.3%; P<0.001). A higher incidence of promoter methylation was also detected in poorly differentiated cancers (93.5%) compared with well-differentiated cancers (50.0%; P<0.001), as well as in tumor samples with positive lymph node metastasis (86.7%) compared with those with negative lymph node metastasis (59.4%; P<0.001). Consistent with the promoter methylation status, the expression level of RKIP was significantly reduced in cancer tissues (36.4%) compared with matched normal tissues (76.6%; P<0.01), as well as in cancers with positive lymph node metastasis (24.4%) compared with those with negative lymph node metastasis (53.1%; P=0.01). Promoter methylation-induced gene silencing significantly correlated with the down regulation of RKIP and the development of ESCC. The results of the present study suggested that the methylation status of the RKIP promoter, when combined with its expression level, may serve as a biomarker for predicting the biological behaviors of ESCC.

Abstract
Esophageal cancer (EC) is one of the most common cancers in China. The purpose of this study was to investigate the updated incidence rates and risk factors of EC in Nan'ao Island, where the EC incidence rate was chronically the highest in southern China. To calculate the annual incidence rate, data on 338 EC cases from Nan'ao Cancer Registry system diagnosed during 2005-2011 were collected. A case-control study was conducted to explore the EC risk factors. One hundred twenty-five alive EC patients diagnosed during 2005-2011 and 250 controls were enrolled into the case-control study. A pre-test questionnaire on demography, dietary factors, drinking water treatment, and behavioral factors was applied to collect information of all participants. The average EC incidence rates during 2005-2011 were 66.09/105, 94.62/105, 36.83/105 for both genders, males and females, respectively, in Nan'ao Island. The EC incidence rate in males was 2.40- to 4.55-fold higher than that in females in the period from 2006 to 2011 (P < 0.05). Considering the onset age, males tend to be much younger than females and reached peak incidence rate at a younger age (P < 0.05). Drinking water treatment by filter (odds ratio [OR] = 0.28, 95% confidence interval [95% CI] = 0.13-0.58) and fruit consumption (OR = 0.55, 95% CI = 0.32-0.94) reduced the risk for EC. On the contrary, the pickled vegetables consumption (OR = 2.64, 95% CI = 1.46-4.76) and liquor drinking (OR = 2.32, 95% CI = 1.21-4.44) increased the risk for EC. These results may be of importance for future research on EC etiology and prevention strategies.

Esophageal cancer in high-risk areas of China: research progress and challenges. Ann Epidemiol 2016; 27:215-221. [PMID: 28007352 DOI: 10.1016/j.annepidem.2016.11.004] [Citation(s) in RCA: 142] [Impact Index Per Article: 17.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2015] [Revised: 11/10/2016] [Accepted: 11/17/2016] [Indexed: 01/23/2023]
Abstract
PURPOSE The extremely high incidence of esophageal cancer in certain rural areas of China has prompted significant intellectual curiosity and research efforts both in China and abroad. METHODS We summarize the research progress over the past several decades in high-risk areas (Linxian, Cixian, Shexian, and Yanting) based on literature research and our field trip (2012-2013). RESULTS Considerable progress in clarifying the environmental risk factors and pathogenesis of esophageal cancer in high-risk areas has been achieved over the past several decades. Epidemiologic evidence suggests that carcinogen exposure and nutritional deficiency, rather than smoking and drinking, may be the major risk factors for esophageal cancer in the Taihang Mountains region, where the incidence of esophageal cancer is among the highest in the world. Two genome-wide association studies have identified variants in PLCE1 at 10q23 that are significantly associated with esophageal cancer risk. Recent whole-exome studies have revealed a comprehensive mutation pattern, in which the C>T transition is the predominant mutation type. CONCLUSIONS Despite extensive research, the main causative factors that contribute to esophageal cancer in high-risk areas have not yet been elucidated. Challenges in this research area include determining the causative role of nitrosamine, identifying other potential carcinogens, and conducting fruitful international collaborative studies based on a multidisciplinary approach. Increased international collaboration will contribute to a better understanding of the etiology of esophageal cancer.

Abstract
BACKGROUND & AIMS Esophageal squamous cell carcinoma (ESCC) is the predominant form of esophageal cancer in Japan. Smoking and drinking alcohol are environmental risk factors for ESCC, whereas single nucleotide polymorphisms in ADH1B and ALDH2, which increase harmful intermediates produced by drinking alcohol, are genetic risk factors. We conducted a large-scale genomic analysis of ESCCs from patients in Japan to determine the mutational landscape of this cancer. METHODS We performed whole-exome sequence analysis of tumor and nontumor esophageal tissues collected from 144 patients with ESCC who underwent surgery at 5 hospitals in Japan. We also performed single-nucleotide polymorphism array-based copy number profile and germline genotype analyses of polymorphisms in ADH1B and ALDH2. Polymorphisms in CYP2A6, which increase harmful effects of smoking, were analyzed. Functions of TET2 mutants were evaluated in KYSE410 and HEK293FT cells. RESULTS A high proportion of mutations in the 144 tumor samples were C to T substitution in CpG dinucleotides (called the CpG signature) and C to G/T substitutions with a flanking 5' thymine (called the APOBEC signature). Based on mutational signatures, patients were assigned to 3 groups, which associated with environmental (drinking and smoking) and genetic (polymorphisms in ALDH2 and CYP2A6) factors. Many tumors contained mutations in genes that regulate the cell cycle (TP53, CCND1, CDKN2A, FBXW7); epigenetic processes (MLL2, EP300, CREBBP, TET2); and the NOTCH (NOTCH1, NOTCH3), WNT (FAT1, YAP1, AJUBA) and receptor-tyrosine kinase-phosphoinositide 3-kinase signaling pathways (PIK3CA, EGFR, ERBB2). Mutations in EP300 and TET2 correlated with shorter survival times, and mutations in ZNF750 associated with an increased number of mutations of the APOBEC signature. Expression of mutant forms of TET2 did not increase cellular levels of 5-hydroxymethylcytosine in HEK293FT cells, whereas knockdown of TET2 increased the invasive activity of KYSE410 ESCC cells. Computational analyses associated the mutations in NFE2L2 we identified with transcriptional activation of its target genes. CONCLUSIONS We associated environmental and genetic factors with base substitution patterns of somatic mutations and provide a registry of genes and pathways that are disrupted in ESCCs. These findings might be used to design specific treatments for patients with esophageal squamous cancers.

Abstract
Background. To explore the correlation between the Arg399Gln polymorphism and susceptibility to esophageal cancer in Korean and Han Chinese individuals in Harbin, China, and its potential interaction with alcohol consumption. Methods. This prospective study included 203 patients with esophageal squamous cell carcinoma; 88 were of Korean descent and 115 were of Han Chinese descent. A group of healthy controls included 105 participants of Korean descent and 105 of Han Chinese descent. Genotyping of the Arg399Gln locus of XRCC1 was performed by PCR-RFLP. Results. The allelic and genotypic frequencies were not significantly different between individuals with esophageal cancer and controls or between individuals of Korean and Han Chinese descent (P > 0.05). However, when individuals with the wild-type Arg/Arg genotype also consumed alcohol, the risk of esophageal cancer was lower (OR = 3.539; 95% CI = 2.039-6.142; P < 0.05). Conclusions. The XRCC1 Arg399Gln polymorphism does not appear to be associated with esophageal cancer in individuals of Korean or Han Chinese descent in Harbin, China. However, alcohol consumption may decrease the risk of esophageal cancer in persons with the wild-type genotype.

Abstract
Worldwide, the highest prevalence of esophageal cancer (EC) occurs in Northern China. High-density SNP arrays allow identification of identity-by-descent (IBD) segments in genomic DNAs representative of shared common ancestral regions. We utilized IBD approaches to map susceptibility loci associated with low-penetrance SNPs in high-risk Henan hereditary esophageal squamous cell carcinoma (ESCC) patients. Affymetrix GeneChip Human mapping SNP array IBD analysis was performed in 32 Henan family history-positive (FH+) ESCC patients, 18 Henan healthy unrelated individuals, and 45 Chinese individuals from a CHB HapMap dataset using PLink (scoring IBD segments individually) and Beagle (scoring of shared IBD segments among case/case vs. control/control pairs) software. Both analyses identified longer IBD segment lengths associated with FH+ ESCC compared to controls. However, there was no strong evidence for a genetic founder effect. Pairing IBD analysis with BEAGLE identified 8 critical IBD segments residing at 2q32.1-q32.2, 3p22.3-p22.2, 4q21.1-q21.21, 7p22.2, 8q23.2-q23.3, 10q23.33-q24.1, 14q24.3 and 16q11.2-q12.1, which were more significantly shared among case/case compared to control/control. The shared IBD segments in FH+ ESCC samples with no overlap with control/CHB Hapmap may encompass potential cancer susceptibility loci. Selected targeted genes, PLCE1, GPT2, SIAH1 and CYP2C-18, residing within the IBD segments at 10q23.33-q24.1 and 16q11.2-q12.1, had statistically significant differential expression in primary ESCC tissues and are likely involved in ESCC carcinogenesis. The importance of these IBD segments to the etiology and development of ESCC in high-risk areas requires further study with expanded sample sizes. This is the first report employing the pairing IBD approach for elucidation of the genetic basis of hereditary ESCC in Henan by applying high throughput SNP array analysis.

Abstract
In preparation for a collaborative multidisciplinary study of the pathogenesis of esophageal cancer, the authors reviewed the published literature to identify similarities and differences between Japan and China in esophageal cancer epidemiology. Esophageal squamous cell carcinoma (ESCC) is the predominant histologic type, while the incidence of esophageal adenocarcinoma remains extremely low in both countries. Numerous epidemiologic studies in both countries show that alcohol consumption and cigarette smoking are contributing risk factors for ESCC. There are differences, however, in many aspects of esophageal cancer between Japan and China, including cancer burden, patterns of incidence and mortality, sex ratio of mortality, risk factor profiles, and genetic variants. Overall incidence and mortality rates are higher in China than in Japan, and variation in mortality and incidence patterns is greater in China than in Japan. During the study period (1987–2000), the decline in age-adjusted mortality rates was more apparent in China than in Japan. Risk factor profiles differed between high- and low-incidence areas within China, but not in Japan. The association of smoking and drinking with ESCC risk appears to be weaker in China than in Japan. Genome-wide association studies in China showed that variants in several chromosome regions conferred increased risk, but only genetic variants in alcohol-metabolizing genes were significantly associated with ESCC risk in Japan. A well-designed multidisciplinary epidemiologic study is needed to examine the role of diet and eating habits in ESCC risk.

Abstract
Raf kinase inhibitory protein (RKIP) has been identified as a member of a novel class of molecules which implicated in cancer progression and suppress the metastatic spread of tumors. The aim of this study was to investigate the promoter methylation and expression of RKIP, determine the prognostic significance of RKIP in gastric cardia adenocarcinoma (GCA). MSP approach and immunohistochemistry methods were used respectively to examine methylation status and protein expression of RKIP in GCA tissues. The frequency of RKIP methylation in GCA tumor tissues (62.1 %) was significantly higher than that in corresponding normal tissues (4.1 %) and was associated with TNM stage, histological differentiation, depth of invasion, LN metastasis, distant metastasis or recurrence, and upper gastrointestinal cancers (UGIC) family history. Positive staining of RKIP in GCA tumor tissues (34.5 %) was significantly decreased than that in corresponding normal tissues (84.1 %) and was associated with RKIP methylation. RKIP may act as a tumor suppressor gene in GCA by regulation of the Raf-1/MEK/ERK signaling pathway. GCA patients in stage III and IV, with positive UGIC family history, and hypermethylation and down-expression of RKIP were most likely to develop metastatic disease and also showed the worse survival. RKIP methylation in GCA was an independent prognostic marker for survival using multivariate Cox regression analysis (P = 0.04). In all, aberrant hypermethylation of RKIP may be one of the mechanisms that lead to loss or down expression of the gene in GCA especially in individuals with UGIC family history. Additionally, hypermethylation and loss of RKIP expression may be used as a marker to predict clinical outcome of GCA.

Abstract
The incidence of esophageal squamous cell carcinoma (ESCC), which is the eighth most common malignancy worldwide, is highest in China. The purpose of this study was to investigate the association between nitrogen compounds in drinking water with the incidence of ESCC by geographical spatial analysis. The incidence of ESCC is high in Shexian county, China, and environmental factors, particularly nitrogen-contaminated drinking water, are the main suspected risk factors. This study focuses on three nitrogen compounds in drinking water, namely, nitrates, nitrites, and ammonia, all of which are derived mainly from domestic garbage and agricultural fertilizer. The study surveyed 48 villages in the Shexian area with a total population of 54,716 (661 adults with ESCC and 54,055 non-cancer subjects). Hot-spot analysis was used to identify spatial clusters with a high incidence of ESCC and a high concentration of nitrogen compounds. Logistic regression analysis was used to detect risk factors for ESCC incidence. Most areas with high concentrations of nitrate nitrogen in drinking water had a high incidence of ESCC. Correlation analysis revealed a significant positive relationship between nitrate concentration and ESCC (P = 0.01). Logistic regression analysis also confirmed that nitrate nitrogen has a significantly higher odds ratio. The results indicate that nitrate nitrogen is associated with ESCC incidence in Shexian county. In conclusion, high concentrations of nitrate nitrogen in drinking water may be a significant risk factor for the incidence of ESCC.

Abstract
BACKGROUND Esophageal cancer is one of the most commonly diagnosed malignant tumors in China. The aim of this study was to provide the representative and comprehensive informations about the long-term mortality trends of this disease in China between 1987 and 2009, using joinpoint regression and generalized additive models (GAMs). METHODS Age-standardized mortality rates (ASMR), overall and truncated (35-64 years), were calculated using the direct calculation method, and joinpoint regression was performed to obtain the estimated annual percentage changes (EAPC). GAMs were fitted to study the effects of age, period and birth cohort on mortality trends. RESULTS ASMR exhibited an overall remarked decline for rural females (EAPC=-2.3 95%CI: -3.3, -1.2), urban males (EAPC=-1.8 95%CI: -2.6, -1.0) and urban females (EAPC=-3.7 95%CI: -4.9, -2.4), but a small drop observed was not statistically significant for rural males (EAPC=-0.9 95%CI: -2.0, 0.3). The declines in ASMR were more noticeable for urban residents in recent years. Among all the residents, age effect showed an progressively increasing trend, whereas cohort effect declined steadily after the year corresponding to the maximum risk value. Period effect seemed to remain substantially unchanged throughout the years. CONCLUSIONS Although variations in mortality rates were observed according to sex and area, the overall decreasing trends in esophageal cancer mortality were found in most Chinese people, aside from rural males. The findings could correspond to the changes in age- and cohort-related factors in the population. Further study is required to understand these potential factors.

Abstract
INTRODUCTION The secreted frizzled-related protein 1 (SFRP1) gene, as a Wnt signaling modulator, is frequently inactivated by promoter methylation in many tumors including gastric cancer, breast cancer, oral squamous cell carcinoma, and esophageal adenocarcinoma. However, the role of SFRP1 in esophageal squamous cell carcinoma (ESCC) is not clear. In this study, we investigated the epigenetic inactivation of the SFRP1 gene in ESCC. METHODS Nine ESCC cell lines, two immortalized human esophageal epithelial cell lines, twenty ESCC tissues, and paired adjacent nontumor tissues were analyzed in the study. Methylation-specific polymerase chain reaction (PCR), bisulfite sequencing, reverse-transcription PCR, immunohistochemistry, and chromatin immunoprecipitation assay were used to detect SFRP1 promoter methylation, expression of the SFRP1 gene, and histone modification in the SFRP1 promoter region. RESULTS The SFRP1 promoter was found to be highly methylated in 95% (19/20) of the ESCC tissues and in nine ESCC cell lines, compared with 65% (13/20) of the paired nontumor tissues. Moreover, we confirmed that complete methylation of the SFRP1 gene promoter was correlated with its greatly reduced expression level. After individual treatment with 5-aza-2'-deoxycytidine (DAC) and trichostatin A (TSA), the messenger RNA (mRNA) level of the SFRP1 gene was not obviously rescued in the EC9706 cell line. Combined incubation with DAC and TSA can, however, substantially increase the SFRP1 mRNA expression level in the EC9706 cell line. Chromatin immunoprecipitation assay showed that acetylated histone H3 and H4 were found in the SFRP1 promoter region. CONCLUSION Promoter hypermethylation of SFRP1 is a frequent event in ESCC. Promoter methylation and histone acetylation may cooperatively regulate expression of the SFRP1 gene.

Abstract
AIM Investigate the promoter methylation of the Thrombospondin-1 (TSP1) gene in gastric cardia adenocarcinoma (GCA). METHODS MSP approach, immunohistochemistry method, and RT-PCR were used respectively to examine the promoter methylation of TSP1, its protein and mRNA expression in tumors and corresponding normal tissues. The expression and concentration of TGF-beta1 were examined respectively by immunohistochemistry and ELISA method. The status of T cell immunity was examined by Flow cytometry analysis. RESULTS TSP1 was methylated in 34/96 (35.4%) tumor specimens, which was significantly higher than that in corresponding normal tissues (P < .001). Protein and mRNA expression of TSP1 in GCA tumor tissues were reduced significantly and were associated with TSP1 methylation. The protein expression of TGF-beta1 was significantly higher in tumor tissues (P < .001) and was associated with TNM stage and histological differentiation. The concentration of active and total TGF-beta1 did not show significant difference between the GCA patients with hypermethylation of TSP1 and without methylation of TSP1 (P > .05). The function of T cell immunity was significantly different between the GCA patients with hypermethylation of TSP1 and without methylation of TSP1. CONCLUSIONS Epigenetic silencing of TSP1 gene by promoter hypermethylation may play an important role in GCA.

Abstract
BACKGROUND AND AIM The FAS and FASL system play an important role in regulating apoptotic cell death. This study was designed to investigate the correlation of FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms with susceptibility to gastric cardiac adenocarcinoma in a population of a high-incidence region of Hebei Province. METHODS FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis in 262 gastric cardiac carcinoma (GCA) patients and 524 healthy controls. RESULTS Family history of upper gastrointestinal cancer (UGIC) might increase the risk of developing GCA (age- and sex-adjusted odds ratio [OR] = 1.38, 95% confidence interval [CI] = 1.02-1.86). The overall allelotype and genotype distributions of FAS-1377 G/A, and FASL-844 T/C polymorphisms in GCA patients did not significantly differ from that in healthy controls (P > 0.05). Compared with individuals with a FAS-670 A/A genotype, individuals with an A/G genotype in a smoker group had a lower risk of developing GCA (age, sex, and family history of UGIC adjusted OR = 0.55, 95% CI = 0.34-0.88). When the genotypes of FAS and FASL single nucleotide polymorphisms (SNP) were combined to analyze, no significant correlation was found between these SNP and the risk for GCA development. CONCLUSION In the high-incidence region of Hebei Province, FAS-1377 G/A and FASL-844 T/C polymorphisms were not associated with the risk of GCA. However, the FAS-670 A/G genotype might decrease the risk of GCA for smoker individuals.

Abstract
Genetic factors are known to be important in the development of esophageal squamous cell carcinoma (ESCC). Epidermal growth factor (EGF) can activate several signaling pathways leading to proliferation, differentiation, and tumorigenesis of epithelial tissues by binding with its receptor. Interindividual variations in EGF production were genetically contributed to EGF +61 G/A polymorphism. The purpose of this study is to investigate the potential association between EGF gene polymorphism and ESCC in a Chinese population. In this study, we analyzed single nucleotide polymorphism of EGF +61 G/A in 158 patients with ESCC and 212 age- and sex-matched controls in a Chinese population using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy and DNA sequencing. The variant genotypes of GA/AA were associated with a significantly decreased risk of ESCC compared with the wild-type homozygote GG (OR = 0.657, 95% CI: 0.434-0.996). However, no significant difference was observed between the EGF +61 G/A polymorphism and the risk of ESCC when the analyses were stratified in terms of age, gender, smoking status, different clinical stage, and lymph node status. The EGF +61 G/A polymorphism is associated with ESCC in a Chinese population. Our data suggests that the EGF gene may play a role in the development of ESCC.

Abstract
AIM Abnormal hypermethylation of CpG islands associated with tumor suppressor genes can lead to transcriptional silencing in neoplasia. The aim of this study was to investigate the promoter methylation and expression of E-cadherin gene in gastric cardiac adenocarcinoma (GCA). METHODS A nested MSP approach, immunohistochemistry method and RT-PCR were used respectively to examine the methylation status of the 5' CpG island of E-cadherin, its protein expression and mRNA expression in tumors and corresponding normal tissues. RESULTS E-cadherin was methylated in 63 of 92 (68.5%) tumor specimens, which was significantly higher than that in corresponding normal tissues (P<0.001). Methylation frequencies of stage III and IV tumor tissues was significantly higher than that in stage I and II tumor tissues (P = 0.01). Methylation status of poor differentiation group was significantly higher than moderate and poor-moderate differentiation groups (P<0.01). By immunostaining 51 of 92 tumor tissues demonstrated heterogeneous, positive immunostaining of tumor tissues (44.6%), significantly different from matched normal tissues (P<0.001). Positive immunostaining of stage III and IV tumor tissues was significantly lower than stage I and II tumor tissues (P<0.01). Poor differentiation group was also significantly lower than moderate and poor-moderate differentiation groups (P<0.05). 80 percent of tumor tissues with E-cadherin gene methylated showed inactivated mRNA expression. CONCLUSIONS High methylation status of the 5' CpG island of E-cadherin gene may be one of the mechanisms in the development of gastric cardiac adenocarcinoma.

Abstract
Golestan Province, located in the south-east littoral of the Caspian Sea in northern Iran, has one of the highest rates of oesophageal cancer (OC) in the world. We review the epidemiologic studies that have investigated the epidemiologic patterns and causes of OC in this area and provide some suggestions for further studies. Oesophageal squamous cell carcinoma (OSCC) constitutes over 90% of all OC cases in Golestan. In retrospective studies, cigarettes and hookah smoking, nass use (a chewing tobacco product), opium consumption, hot tea drinking, poor oral health, low intake of fresh fruit and vegetables, and low socioeconomic status have been associated with higher risk of OSCC in Golestan. However, the association of tobacco with OSCC in this area is not as strong as that seen in Western countries. Alcohol is consumed by a very small percentage of the population and is not a risk factor for OSCC in this area. Other factors, such as polycyclic aromatic hydrocarbons, N-nitroso compounds, drinking water contaminants, infections, food contamination with mycotoxins, and genetic factors merit further investigation as risk factors for OSCC in Golestan. An ongoing cohort study in this area is an important resource for studying some of these factors and also for confirming the previously found associations.

Abstract
Ras-association domain family 1A (RASSF1A) gene, a candidate tumor suppressor gene, is inactivated in several human tumors, usually by hypermethylation of its promoter region. RASSF1A induces cell cycle arrest through inhibition of cyclin D1 accumulation. In this work, the promoter methylation status of the RASSF1A in 92 gastric cardia adenocarcinoma (GCA) and corresponding normal tissues were investigated using Methylation-specific PCR (MSP) approach, immunohistochemistry method and RT-PCR were used respectively to examine the protein expression and mRNA expression of RASSF1A in tumors and corresponding normal tissues. Cyclin D1 expression was examined by immunohistochemistry. RASSF1A was methylated in 54/92 (58.7%) tumor specimens, which was significantly higher than that in corresponding normal tissues (p <.001). Methylation frequencies of stage III and IV tumor tissues were significantly higher than that in stage I and II tumor tissues (p <.05). By immunostaining, 43/92 (46.7%) tumor tissues demonstrated heterogeneous, positive immunostaining of tumor tissues was significantly reduced with comparison to matched normal tissues (p <.001). mRNA expressions of RASSF1A in GCA tumor tissues were reduced significantly with comparison to the corresponding normal tissues (OD value: 0.2376 +/- 0.2315 vs 0.6874 +/- 0.2668, p <.001). RASSF1A mRNA expression in methylation group of GCA was significantly different from that in unmethylation group (p <.001). Cyclin D1 hyper-expression was found in 72/92 (78.3%) cases and correlated with RASSF1A methylation (p <.05). Our data suggested that epigenetic silencing of RASSF1A gene expression by promoter hypermethylation may play an important role in GCA.

Abstract
Esophageal cancer is highly aggressive and is a common cancer both worldwide and in the US. In the past two decades, the incidence and mortality of esophageal cancer in the US have both increased, where as the incidence and mortality of other cancers have decreased. Although esophageal squamous cell carcinoma and esophageal adenocarcinoma differ in their histology and epidemiologic distribution, some of their risk factors (e.g. dietary deficiencies and tobacco) and underlying mechanisms of carcinogenesis are the same. Intensive research into risk factors combined with the ability to identify precursor lesions (e.g.squamous dysplasia in esophageal squamous cell carcinoma and Barrett's esophagus in esophageal adenocarcinoma) has paved the way for studies of chemoprevention for esophageal cancer, some of which have shown promising results.

Abstract
Matrix metalloproteinases-9 (MMP-9) plays important roles in tumor invasion and metastasis by degrading extracellular matrix components. Variations in the DNA sequence in the MMP-9 gene may lead to altered MMP-9 production and/or activity, and so this may modulate an individual's susceptibility to esophageal squamous cell carcinoma (ESCC). To test this hypothesis, we investigated the association of the MMP-9 polymorphisms and their haplotypes with the risk of ESCC in a Chinese population. There were significant differences in the genotype and allele distribution of P574R polymorphism of the MMP-9 gene among cases and controls. The P574R GG genotypes were associated with a significantly increased risk of ESCC as compared with the CC genotypes (odds ratio [OR] = 4.08; 95% confidence interval [CI]: 1.58-10.52; p = 0.00). Compared with 279R-574P haplotype, 279R-574R (OR = 3.52; 95% CI: 1.99-6.25) and 279Q-574P (OR = 2.16; 95% CI: 1.07-4.35) haplotypes can increase the onset risk of ESCC statistically, but the role of 279R-574R haplotype is more obvious. MMP-9 P574R polymorphisms and P574R-R279Q haplotype are significantly associated with the risk of ESCC. Our study shows for the first time that MMP-9 gene P574R polymorphism may contribute to a genetic risk factor for ESCC in a Chinese population.

Abstract
PTEN, as a tumor suppressor gene, plays an important role in regulating cell growth, proliferation, and apoptosis. Two common polymorphisms, -9C/G and IVS4 (-/+), may alter susceptibility to the disease. To test the hypothesis that the genetic variations of PTEN play a role in the etiology of esophageal squamous cell carcinoma (ESCC) and gastric cardiac adenocarcinoma (GCA), a population-based case-control study was conducted in 350 ESCC patients, 257 GCA patients, and 634 healthy controls from a high-incidence region of Hebei province, China. The PTEN polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP). The results showed that the family history of upper gastrointestinal cancer (UGIC) significantly increased the risk of developing ESCC and GCA (the age, gender and smoking status adjusted OR = 1.73 and 1.67; 95% CI = 1.29-2.32 and 1.28-2.19, respectively). The overall distribution of the PTEN -9C/G genotype was not significantly different between cancer patients and controls. Compared with the PTEN IVS4-/- genotype, the IVS4+/+ genotype significantly decreased the risk of ESCC and GCA development, the adjusted OR was 0.64 (95% CI = 0.44-0.94) and 0.63 (95% CI = 0.41-0.98), respectively. Stratification analysis by gender, age, smoking status and family history of UGIC showed that the PTEN IVS4-/+ genotype only reduced the risk of ESCC (adjusted OR = 0.55, 95%CI = 0.34-0.90) among subjects with family history of UGIC. While the IVS4+/+ genotype decreased the susceptibility to both ESCC and GCA (adjusted OR = 0.61 and 0.57, 95% CI = 0.37-0.98 and 0.34-0.98, respectively) among male subjects, the IVS4+/+ genotype only decreased the risk of ESCC development among subjects younger than 55 years (adjusted OR = 0.43, 95% CI = 0.21-0.85). In addition, the haplotype analysis found that the -9C/IVS4- haplotype increased the risk of developing ESCC and GCA (OR = 1.31 and 1.24, 95% CI = 1.08-1.58 and 1.001-1.53). Our results suggested that the PTEN IVS4+/+ homozygote may play a protective role in the development of ESCC and GCA, while the haplotype -9C/IVS4- might be the risk factor of the development of ESCC and GCA in the high incidence region population of Hebei province, China.

Abstract
E-cadherin (CDH1) is a tumor suppressor involved in epithelial cell-cell interactions. Single nucleotide polymorphisms (SNP) in the CDH1 gene, -160C/A and -347G/GA in the 5'-promoter region and +54C/T in the 3'-untranslated region (UTR) have been shown to be associated with tumor development and progression via modifying transcriptional activity, mRNA stability or protein expression. To investigate the influence of CDH1 SNP on susceptibility to esophageal squamous cell carcinomas (ESCC) and gastric cardia adenocarcinomas (GCA), a case-control study was conducted among 333 ESCC patients, 239 GCA patients and 343 controls from a northern Chinese population. CDH1 polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis. The results showed that; (i) genotypes with the +54C allele (C/C or C/T) significantly increased the risk of developing both ESCC and GCA compared to the +54T/T genotype (age and gender adjusted odds ratio [OR] = 1.45 and 2.28, 95% confidence interval [CI] = 1.06-1.99 and 1.58-3.30, respectively), and this association was significant only among non-smokers (OR = 1.68 and 2.64, 95% CI = 1.01-2.80 and 1.43-4.87 for ESCC and GCA, respectively), and individuals without a family history of upper gastrointestinal cancer (OR = 2.63 and 2.97, 95% CI = 1.36-5.10 and 95% CI = 1.32-6.68 for ESCC and GCA, respectively); (ii) compared with the -347G/G genotype, the -347GA and GA/GA genotypes significantly increased the risk of developing GCA (OR = 1.45, 95 % CI = 1.03-2.04); (iii) there was a significant association of CDH1-160C/-347G/+54C and -160C/-347GA/+54C haplotypes with the development of GCA, compared with the -160C/-347G/+54T haplotype (OR = 1.80 and 2.21, 95% CI = 1.33-2.44 and 1.43-3.42, respectively); and (iv) the influence of CDH1 SNP on the depth of tumor invasion and lymphatic metastasis in ESCC and GCA patients was not observed in this study. The present study indicates that CDH1 polymorphisms might modify susceptibility to ESCC and/or GCA.

Abstract
AIM To investigate the possible association of three SNPs, XRCC2 C41657T, XRCC2 G4234C and XRCC3 A17893G with susceptibility to esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) in a population of northern China. METHODS XRCC2 C41657T, XRCC2 G4234C and XRCC3 A17893G SNP were genotyped by polymerase-chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis in 583 cancer patients (329 ESCC and 254 GCA) and 614 healthy controls. RESULTS The genotype distribution of the XRCC2 C41657T in ESCC and GCA patients were significantly different from that in healthy controls (P values = 0.04 and 0.04 respectively). And a significant difference was found in the allele distribution of GCA patients from that in controls (P = 0.01). The XRCC2 C41657T polymorphism was associated with a modest enhancement in ESCC risk and GCA risk: OR for C/T genotype was 1.38 (1.01-1.89) in GCA risk and for T/T genotype was 2.24 (1.10-4.57) in ESCC risk. When stratified for age, smoking status and family history of UGIC, the C/T genotype showed a modest significant trend on the risk of GCA patients in the groups of age < or =50 years and non-smokers, the adjusted OR were 2.84 (1.21-6.66) and 1.62 (1.06-2.49). The T/T genotype significantly increased the susceptibility of GCA patients in negative family history of UGIC (3.04, 1.02-8.32) and to ESCC patients in the group of age >50 years (3.03, 1.31-6.98), Negative family of UGIC (3.03, 1.12-7.07) and smokers (2.64, 1.02-6.83). The genotype and allele distribution of XRCC2 G4234C and XRCC3 A17893G in ESCC and GCA patients were not significantly different from that in healthy controls (all P values were above 0.05). CONCLUSION In this study, we found that the C41657T polymorphism of XRCC2 genes might modify the risk of ESCC and GCA development.

Abstract
Background Oesophageal carcinoma is one of the most common cancers worldwide. Its incidence and mortality rates show a wide geographical variation at a world and regional level. Geographic mapping of age-standardized, cause-specific death rates at a municipal level could be a helpful and powerful tool for providing clues leading to a better understanding of its aetiology. Methods This study sought to describe the geographic distribution of oesophageal cancer mortality for Spain's 8077 towns, using the autoregressive spatial model proposed by Besag, York and Mollié. Maps were plotted, depicting standardised mortality ratios, smoothed relative risk (RR) estimates, and the spatial pattern of the posterior probability of RR being greater than 1. Results Important differences associated with area of residence were observed in risk of dying from oesophageal cancer in Spain during the study period (1989–1998). Among men, excess risk appeared across the north of the country, along a band spanning the length of the Cantabrian coastline, Navarre, the north of Castile & León and the north-west of La Rioja. Excess risk was likewise observed in the provinces of Cadiz and part of Seville in Andalusia, the islands of Tenerife and Gran Canaria, and some towns in the Barcelona and Gerona areas. Among women, there was a noteworthy absence of risk along the mid-section of the Cantabrian seaboard, and increases in mortality, not observed for men, in the west of Extremadura and south-east of Andalusia. Conclusion These major gender- and area-related geographical differences in risk would seem to reflect differences in the prevalence of some well-established and modifiable risk factors, including smoking, alcohol consumption, obesity and diet. In addition, excess risks were in evidence for both sexes in some areas, possibly suggesting the implication of certain local environmental or socio-cultural factors. From a public health standpoint, small-area studies could be very useful for identifying locations where epidemiological research and intervention measures ought to receive priority, given the potential for reducing risk in certain places.

Abstract
An innovative population-based case-control study was conducted in a national mortality survey to assess the hazards of tobacco use on esophageal cancer among Chinese men. Cases were 19,734 males aged 35 years or older, who died of esophageal cancer during 1986-1988. Controls were 104,846 male living spouses of the same age when their wife died (of any cause) during the same period in the same county or city. The absolute esophageal cancer death rates were higher in smokers than those in nonsmokers in all geographical groups. The relative risks for esophageal cancer were 1.88 (95% CI: 1.73-2.05) and 1.39 (95% CI: 1.28-1.50) in urban and rural men, respectively, after adjustment for other relevant covariates including age group (5 years) and locality. When the calculation was restricted to men aged 35-69, the risk ratios for current cigarette smokers increased significantly with increasing number of cigarettes smoked daily and duration of smoking. Tobacco use, in any form, is an important risk factor for esophageal cancer in Chinese men. Selecting living spouses as controls is a unique and useful approach in the design of case-control studies of cigarette smoking.

Abstract
Esophageal cancer is the 6th most common cancer in the world, and genetic factors (p53 mutations) in addition to the environmental factors (food, nutrition, smoking, drinking, etc.) are involved in its development. In this study, the association between the both factors, environmental risk factors for esophageal cancer and p53 mutations, in tumor tissues was investigated in 77 patients living in a high-incidence area and 50 patients living in a low-incidence area in Hebei Province, China. Among these patients, p53 mutations were observed in about 50%, without regional differences in the respective frequencies. G:C>A:T (G to A or C to T) transition mutations were the major type of mutations observed in patients in the high-incidence area (19 patients, 50%), whereas G:C>A:T transitions and insertions were observed with equal frequency (8 patients, 33.3%) in the low-incidence area. As for the association with environmental factors, p53 mutations occurred with higher frequency in patients with a daily intake of spicy foods and in those who used unboiled well water in the low-incidence area. Logistic regression analysis showed no association between food intakes and p53 mutations in high- and low-incidence areas. Thus, higher frequency of spicy food intake and use of unboiled well water may be risk factors of esophageal cancer via p53 mutations in China.

Abstract
Together with adenocarcinoma, epidermoid esophageal carcinoma is the most clinically important neoplasm of the esophagus. Because of the low incidence of epidermoid esophageal carcinoma in the general population, strategies for its early diagnosis are not a priority compared with other neoplasms. However, because survival is low when the disease is diagnosed in symptomatic patients (less than 20% at 5 years), methods for its early diagnosis should be investigated. The use of cytology or Lugol chromoendoscopy in countries with a high incidence of epidermoid carcinoma or in individuals at increased risk (mainly alcoholics and smokers) has allowed early diagnosis and potentially curative treatment, substantially increasing life expectancy in this group of patients. These results should stimulate the evaluation and eventual implementation of programs to achieve early diagnosis and therefore greater survival in patients with epidermoid esophageal carcinoma in Western countries.

Abstract
AIM: To investigate association of the 2G or1G single nucleotide polymorphism (SNP) in matrix metalloproteinase 1 (MMP1) promoter with susceptibility to esophageal squam-ous cell carcinoma (ESCC) and gastric cardiac adenocarcinoma (GCA) in a population of North China.
METHODS: MMP1 promoter SNP was genotyped by polymerase-chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis in 417 cancer patients (234 ESCC and 183 GCA) and 350 healthy controls.
RESULTS: The genotype frequencies of the MMP1 promoter SNP in healthy controls were 55.4% (2G/2G), 30% (1G/2G) and 14.6% (1G/1G), respectively. The genotype and allelotype distribution in ESCC and GCA patients was not significantly different from that in healthy controls (all P values were above 0.05). Compared with the 1G/1G genotype, neither the 2G/2G nor in combination with the 1G/2G genotype significantly modified the risk of developing ESCC and GCA, the adjusted odds ratio was 1.28 (95%CI = 0.78-2.09), 1.23 (95%CI = 0.38-2.05) in ESCC and 1.39 (95%CI = 0.80-2.41), 1.34 (95%CI = 0.74-2.40) in GCA, respectively. When stratified by smoking status and family history of upper gastrointestinal cancer, the 2G/2G genotype alone or in combination with the 1G/2G genotype also did not show any significant influence on the risk of ESCC and GCA development. In addition, influence of the MMP1 SNP on lymphatic metastasis in ESCC and GCA was also not obs-erved.
CONCLUSION: The 2G or 1G SNP in the MMP1 promoter might not modify the risk of ESCC and GCA development and might not be used as a stratification marker to predict the potential of lymphatic metastasis in these two tumor types.

Abstract
AIM: To investigate the possible association of G→A single nucleotide polymorphism (SNP) at the -1082 position of interleukin (IL)-10 promoter with susceptibility to esophageal squamous cell carcinoma (ESCC) and gastric cardiac adenocarcinoma (GCA) in a population of a high incidence region of North China.
METHODS: IL-10-G1082A promoter SNP was genotyped by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) in 355 cancer patients (203 ESCC and 152 GCA) and 443 healthy controls.
RESULTS: Smoking significantly increased the risk of ESCC and GCA development (the age and sex adjusted OR = 1.42 and 2.64, 95%CI = 1.11-1.81 and 1.46-4.76, respectively). Similarly, family history of upper gastrointestinal cancer (UGIC) significantly increased the risk of developing ESCC and GCA (the age and sex adjusted OR = 1.44 and 3.10, 95%CI = 1.18-1.75 and 1.94-4.97, respectively). The A/A, A/G and G/G genotype frequencies of IL-10-G1082A were 60.3%, 37.0% and 2.7% in healthy controls, 57.6%, 39.9% and 2.5% in ESCC and 61.2%, 36.8% and 2.0% in GCA patients, respectively. The frequencies of A and G alleles were 78.8% and 21.2% in healthy controls, 77.6% and 22.4% in ESCC patients and 79.6%, 20.4% in GCA patients. The distribution of genotype and allelotype in ESCC and GCA patients was not significantly different from that in healthy controls (P>0.05). Compared to the A/A genotype, the combination of A/G and G/G genotypes did not show a significant effect on the risk of developing ESCC and GCA; the adjusted odds ratio was 0.92 (95% CI = 0.76-1.11) in ESCC and 0.95 (95% CI = 0.61-1.46) in GCA, respectively. When stratified for smoking status and family history of UGIC, the combination of A/G and G/G genotypes also did not show any significant influence on the risk of ESCC and GCA development compared to A/A genotypes.
CONCLUSION: IL-10-G1082A polymorphism might not be used as a stratification marker to predicate the risk of ESCC and GCA development in North China.

Abstract
Abstract
Knowledge of the incidence of cancer is a fundamental requirement of rational planning and monitoring of cancer control programs. The lack of national-level information systems on health indicators in China means that estimation methods are required. Estimates and projections of national level cancer mortality have been previously made using sample surveys of deaths. Using these mortality data, incidence rates in 2000 and 2005 were estimated by means of the ratio of cancer cases/deaths (by site, age, and sex) in good quality cancer registries in China. A total of 2.1 million cancer cases were estimated for the year 2000 (1.3 million in men, 0.8 million in women), with the most common sites being lung, liver, and stomach in men, and breast, lung, and stomach in women. The total number of new cases is expected to increase by 14.6% by 2005, primarily as a result of population growth and aging. In addition, the rising rates of lung cancer incidence (in both sexes) and breast cancer mean that there will be much greater increases in the number of cases at these two sites (27% for lung cancer in men, 38% for lung and breast cancer in women). These two cancers are now the priorities for cancer prevention, early detection, and therapy in China.

Abstract
PURPOSE Folate deficiency is considered to increase the risk of developing esophageal cancer. Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme involved in folate metabolism. A single C --> T substitution at nucleotide 677 of the MTHFR cDNA influences enzyme activity. The purpose of this study is to compare the association of the MTHFR C677T polymorphism with susceptibility to esophageal squamous cell carcinoma (ESCC). METHODS Using real-time PCR and melting curve analysis, the MTHFR C677T genotypes were determined in 430 patients with ESCC (241 German Caucasians and 189 northern Chinese) and 397 unrelated healthy controls (256 German Caucasians and 141 northern Chinese). RESULTS A significant difference in MTHFR C677T genotype distribution was observed between German Caucasian controls (C/C, 41.8%, C/T, 44.9%, T/T, 13.3%) and northern Chinese controls (C/C, 17.7%, C/T, 38.3%, T/T, 44.0%) (chi(2)=52.19, P<0.001). The distribution of the MTHFR C677T genotypes among German ESCC patients (C/C, 39.0%, C/T, 48.1%, T/T, 12.9%) was not significantly different from that among healthy controls (chi(2)=0.531, P=0.767). In contrast, the frequency of the C/C genotype among Chinese ESCC patients (8.5%) was significantly lower than among Chinese healthy controls (17.7%) (chi(2)=6.37, P=0.012). The C/C genotype was correlated with a significantly reduced risk for the development of ESCC as compared to the combination of C/T and T/T genotypes (adjusted OR=0.38, 95% CI=0.16-0.88). CONCLUSIONS Our results suggest that, in contrast to German Caucasians, the MTHFR 677CC homozygous wild-type plays a protective role in the development of ESCC in the northern Chinese population.

Abstract
AIM: To investigate the possible association of microsomal epoxide hydrolase (mEH) Tyr113His polymorphism with susceptibility to esophageal squamous cell carcinoma (ESCC) in a population of North China.
METHODS: The mEH Tyr113His genotypes were determined by polymerase-chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis in 257 patients with esophageal squamous cell carcinoma (ESCC) and 252 healthy subjects as a control group.
RESULTS: The frequencies for Tyr and His alleles were 44.2%, 55.8% in ESCC patients, and 44.0% and 56.0% in healthy subjects, respectively. No statistic difference in allele distribution was observed between ESCC patients and controls (χ2 = 0.008, P = 0.929). The overall genotype distribution difference was not observed between cancer cases and controls (χ2 = 2.116, P = 0.347). Compared with Tyr/Tyr genotype, neither His/His genotype nor in combination with Tyr/His genotype significantly modified the risk of the development of ESCC, the adjusted odds ratio was 1.076 (95%CI = 0.850-1.361) and 0.756 (95%CI = 0.493-1.157), respectively. When stratified for sex, age, smoking status and family history of upper gastrointestinal cancer, His/His genotype alone or in combination with Tyr/His genotype also did not show any significant influence on the risk of developing ESCC.
CONCLUSION: MEH Tyr113His polymorphism may not be used as a stratification marker in screening individuals at a high risk of ESCC.

Abstract
A first analysis of time trends in cancer mortality in China at the national level is presented. Using a joinpoint regression model, based on data from a national mortality routine reporting system in China (CHIS), time trends in mortality for 9 major cancers are analyzed. Between 1987 and 1999, the age-standardized mortality rates for all cancers combined declined slightly in rural areas but have increased since 1996 in urban areas. The mortality rates for cancers in oesophagus, stomach, cervix uteri, leukaemia (except for urban males after 1996) and nasopharynx declined, while lung cancer and female breast cancer showed significant increasing trends in both urban and rural areas and for both sexes. Cancers of the colon-rectum and liver had different trends in mortality in urban and rural populations. The trends in age-specific mortality rates suggest some different trends in the younger population, which may presage future overall trends, for example, increasing mortality from cancer of the cervix. The observed trends primarily reflect the dramatic changes in socioeconomic circumstances and lifestyles in China in the last 2 decades. Tobacco smoking remains a major problem, with increases in mortality from lung cancer. The improvements in socioeconomic status, diet and nutrition may be responsible for the declining risk of some cancers (oesophagus, stomach and nasopharynx), while increasing the risk for others (breast and colon-rectum). Screening programs (especially for cervix cancer), and more available and better facilities for cancer therapy, may have helped to reduce mortality for several cancers. The large increases in the absolute number of deaths that resulted from the increasing and aging population are much more important in determining the future cancer burden than any changes due to change in risk, emphasizing the increasing importance of cancer as a health problem in the 21st century in China.

Abstract
AIM: To investigate the association of the NQO1 (C609T) polymorphism with susceptibility to esophageal squamous cell carcinoma (ESCC) and gastric cardiac adenocarcinoma (GCA) in North China.
METHODS: The NQO1 C609T genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 317 cancer patients (193 ESCC and 124 GCA) and 165 unrelated healthy controls.
RESULTS: The NQO1 C609T C/C, C/T and T/T genotype frequency among healthy controls was 31.5%, 52.1% and 16.4% respectively. The NQO1 T/T genotype frequency among ESCC patients (25.9%) was significantly higher than that among healthy controls (χ2 = 4.79, P = 0.028). The NQO1 T/T genotype significantly increased the risk for developing ESCC compared with the combination of C/C and C/T genotypes, with an age, sex and smoking status adjusted odds ratio (OR) of 1.78 (1.04-2.98). This increased susceptibility was pronounced in ESCC patients with family histories of upper gastrointestinal cancers (UGIC) (adjusted OR = 2.20, 95%CI: 1.18-3.98). Similarly, the susceptibility of the NQO1 T/T genotype to GCA development was also observed among patients with family histories of UGIC, with an adjusted odds ratio of 2.55 (95%CI: 1.21-5.23), whereas no difference in NQO1 genotype distribution was shown among patients without family histories of UGIC.
CONCLUSION: Determination of the NQO1 C609T genotype may be used as a stratification marker to predicate the individuals at high risk for developing ESCC and GCA in North China.

Abstract
AIM: In order to detect risk factors for esophageal cancer, a national research program was carried out during the Eighth Five-Year Plan (from 1991 to 1995).
METHODS: Cixian County and Chichen County in Hebei Province were selected as the index and the control for the study fields with higher or lower incidence of esophagus cancer in China, respectively. In these areas, we investigated the pollution of three nitrogenous compounds in well water for drinking and the use of nitrogen fertilizer in farming.
RESULTS: In well water, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen were 8.77 mg/L, 0.014 mg/L and 0.009 mg/L in Cixian County in 1993, respectively. They were significantly higher than their levels (3.84 mg/L, 0.004 mg/L and 0.004 mg/L) in Chichen County (P < 0.01, t = 6.281, t = 3.784, t = 3.775). There was a trend that the nitrogenous compounds in well water increased from 1993 to 1996. The amount of nitrogen fertilizer used in farming was 787.6 kg per hectare land in Cixian County in 1991, significantly higher than 186 kg per hectare in Chichen County (t = 9.603, P < 0.001).
CONCLUSION: These investigations indicate that the pollution of nitrogenous compounds in well water for drinking is closely related to the use of nitrogen fertilizer in farming, and there is a significantly positive correlation between the level of three nitrogenous compounds in well water and the mortality of esophageal cancer (correlation coefficient = 0.5992). We suggest that improvement of well system for drinking water quality should be an effective measure for esophageal cancer prevention and control in rural areas.

Abstract
The current study was designed to investigate the role of common foods in the etiology of esophageal cancer in the Chaoshan region of China. A large case-control study was conducted to investigate 1248 patients with squamous cell carcinoma of the esophagus and 1248 controls matched by sex, age, and hospitals. After adjusting for the effects of sex, age, occupation, areas of residence, income, alcohol intake, and cigarette usage, a strong association with a clear dose-response relationship was observed between the fermented fish sauce eaten weekly and esophageal cancer (P for trend less than 0.001). The results for pickles were similar to those for fermented fish sauce. A protective effect of fruits on esophageal cancer was observed, and this risk decreased (P for trend less than 0.001) as frequencies of fresh fruit intake increased. The risks from sowbelly and kipper were significantly higher in consumers than in nonconsumer, but the dose-response relationship was not statistically significant. No significant effects, however, were detected from vegetables, smoked foods, and so on. To the authors' knowledge, this is the first report on the relationship between fish juice and high risk of esophageal cancer in a population. Further epidemiological and experimental study are required to find a biological causal relationship between them.

Abstract
The multiple occurrence of squamous cell carcinoma is frequent in the upper aerodigestive tract (UADT). Risk factors not only for esophageal cancer, but also for multiple cancer in the UADT, were reviewed. Both cigarettes smoking and alcohol drinking are will known risk factors for esophageal cancer. The joint effect of these 2 factors on the occurrence of esophageal cancer is considered to be synergetic, but familial aggregation of esophageal cancer is also reported. Regarding the multiple occurrence of cancer of the UADT, both heavy smoking and heavy drinking play an important role. In addition, our studies revealed that a family history of UADT cancer might also be a risk factor for multiple cancer. Recent improvement of molecular biology techniques have helped to show that tumor-suppressor genes, such as p53 and FHIT, may be candidates for target genes of these risk factors.

Abstract
Squamous cell cancer is the most common neoplasm of the oesophagus worldwide, with an enormous variation in its global incidence. Several risk factors, such as achalasia, Plummer-Vinson syndrome, coeliac disease and nutritional factors, have been identified. The surveillance of patients, especially those with tylosis or caustic ingestion, has been recommended. Vital staining with iodine may improve the diagnosis of early cancer. The endoscopic management of early cancer and dysplasia by minimal invasive techniques such as photodynamic therapy or mucosal resection has become attractive for many of these patients with co-morbidity.
