Synchronous primary esophageal squamous cell carcinoma and gastric adenocarcinoma: analysis of 41 cases treated in a single institution.

ABSTRACT: The present study investigated the treatment and survival outcomes of patients with synchronous primary esophageal squamous cell carcinoma and gastric adenocarcinoma. The medical records of 10,783 patients with primary esophageal squamous cancer treated at our institution between 1995 and 2012 were retrospectively reviewed. Overall survival (OS) rates were calculated using the Kaplan-Meier method. The incidence was 0.38% (41/10,783). Of these 41 patients, 26 underwent curative surgery, ten received palliative chemotherapy or radiotherapy, and five received no treatment. The median OS of the surgery, palliative-therapy, and treatment-free groups was 17.1, 9.0, and 3.8 months, respectively. The 1-, 3-, 5-, and 10-year OS rates for the surgery group were 77%, 45%, 33%, and 19%, respectively. No significant differences in median OS were observed between the surgery group and the historical cohort of isolated esophageal cancer (n = 186) (17.1 vs. 21.0 months, P = 0.061) or isolated gastric cancer (n = 51) (17.1 vs. 28.9 months, P = 0.875), or between the palliative-therapy group and its corresponding historical cohort (n = 30) (9.0 vs. 8.3 months, P = 0.862). The survival outcomes of patients with synchronous primary esophageal squamous and gastric cancers were not worse than those of patients with isolated esophageal cancer or isolated gastric cancer.

Synchronous occurrence of hereditary gastric adenocarcinoma, gastrointestinal stromal tumor, and esophageal small cell and squamous carcinoma in situ: an extremely rare case report.

Project description:BACKGROUND:Hereditary diffuse gastric carcinoma (HDGC) accounts for 1-3% of all gastric carcinomas. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal (GI) tract but they comprise fewer than 1% of all GI malignancies. Small-cell carcinoma (SmCC) is a rare histological type of esophageal carcinoma, accounting for 0.4% to 2.8% of all esophageal tumors. Co-occurrence of SmCC with esophageal tumors caused by squamous carcinoma is also very uncommon. Although multiple primary malignancies are no longer rare in clinical practice, the simultaneous appearance of HDGC, GIST, esophageal small cell and squamous carcinoma in situ is extremely rare and very few cases have been reported. CASE PRESENTATION:We present a case of a 53 year-old woman with synchronous occurrence of four malignancies including HDGC, GIST, esophageal small cell- and local squamous carcinoma in situ. A total gastrectomy with D2 lymph node dissection and postoperative adjuvant chemotherapy with oxaliplatin and paclitaxel liposome were performed. After a 1-year follow-up, this patient was still in good condition with no evidence of recurrence. CONCLUSION:This is the unique case that describes the co-existence of the aforementioned four types of neoplasm. This case demonstrates that a diagnosis of gastric cancer does not preclude the presence of other malignancies and every case should be thoroughly analyzed to avoid missing other problems, which may worsen the prognosis.

Human esophageal dysplasia (16 cases) vs. esophageal squamous cell carcinoma (59 cases)

Project description:Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations.

A shared susceptibility locus in PLCE1 at 10q23 for gastric adenocarcinoma and esophageal squamous cell carcinoma.

Project description:We conducted a genome-wide association study of gastric cancer and esophageal squamous cell carcinoma (ESCC) in ethnic Chinese subjects in which we genotyped 551,152 SNPs. We report a combined analysis of 2,240 gastric cancer cases, 2,115 ESCC cases and 3,302 controls drawn from five studies. In logistic regression models adjusted for age, sex and study, multiple variants at 10q23 had genome-wide significance for gastric cancer and ESCC independently. A notable signal was rs2274223, a nonsynonymous SNP located in PLCE1, for gastric cancer (P = 8.40 x 10(-9); per-allele odds ratio (OR) = 1.31) and ESCC (P = 3.85 x 10(-9); OR = 1.34). The association with gastric cancer differed by anatomic subsite. For tumors in the cardia the association was stronger (P = 4.19 x 10(-15); OR = 1.57), and for those in the noncardia stomach it was absent (P = 0.44; OR = 1.05). Our findings at 10q23 could provide insight into the high incidence of both cancers in China.

Esophageal squamous cell carcinoma and gastric cardia adenocarcinoma shared susceptibility locus in PLCE1: a meta-analysis.

Project description:Background and objectiveTwo recent genome-wide association studies have identified a shared susceptibility variation PLCE1 rs2274223 for esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinomas (GCA). Subsequent case-control studies have reported this association in other populations. However, the findings were controversial and the effect remains undetermined. Our aim is to provide a precise quantification of the association between PLCE1 rs2274223 variation and the risk of ESCC and GCA.MethodsStudies were identified by a literature search in MEDLINE and EMBASE databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association in allele, dominant, recessive, homozygous, and heterozygous models.ResultsTen articles were identified, including 22156 ESCC cases and 28803 controls, 5197 GCA cases and 17613 controls. Overall, PLCE1 rs2274223 G allele (G vs. A: OR=1.26, 95% CI: 1.15-1.39 for ESCC; OR=1.51, 95% CI: 1.35-1.69 for GCA) and its carrier (GG +AG vs. AA: OR = 1.23; 95% CI =1.02-1.49 for ESCC; OR =1.62; 95% CI =1.15-2.29 for GCA) were significantly associated with the risk of ESCC and GCA. In stratified analysis by ethnicity, significant association of PLCE1 rs2274223 G allele and the risk of ESCC (OR=1.33, 95% CI 1.21-1.45) and GCA (OR =1.56, 95% CI: 1.47-1.64) was observed in Chinese population.ConclusionsOur meta-analysis results indicated that PLCE1 rs2274223 G allele significantly contributed to the risk of ESCC and GCA, especially in Chinese population.

Esophageal Squamous Cell Carcinoma and Gastric Cardia Adenocarcinoma Shared Susceptibility Locus in C20orf54: Evidence from Published Studies.

Project description:This study aimed to determine whether C20orf54 rs13042395 polymorphism modify the risk of esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinomas (GCA) in common population. We conducted a systematic literature review and evaluated the quality of included studies based on Newcastle-Ottawa Scale (NOS). Pooled odds ratios (ORs) and corresponding 95% confidence intervals (95%CIs) were calculated to estimate the strengths of the associations. 9 articles (10 studies) were identified for synthesis analyses. Overall, the results indicated that the C20orf54 rs13042395 genotype was subtly decrease the risk of ESCC (T vs. C: OR?=?0.95; 95%CI?=?0.90-0.99; P?=?0.02) and the rs13042395 polymorphism was associated with a decreased risk of GCA (T vs. C: OR?=?0.95; 95%CI?=?0.91-0.98; P?<?0.01). The subsets were divided by smoking and drinking status, but none of the genetic comparisons reached statistical significance. Subgroup analysis was also stratified by body mass index (BMI), rs13042395 polymorphism was significantly associated with a subtly decreased cancer risk in under-weight group and normal group, but no association was observed in over-weight group. In conclusion, C20orf54 rs13042395 polymorphism was significantly associated with decreased ESCC and GCA risk especially for the subjects with under-weight or normal.

PLCE1 mRNA and protein expression and survival of patients with esophageal squamous cell carcinoma and gastric adenocarcinoma.

Project description:BACKGROUND:Germline genetic variants in PLCE1 (10q23) have demonstrated consistent associations with risk of esophageal squamous cell carcinoma (ESCC) and gastric cancer among Chinese. We evaluated PLCE1 mRNA and protein expression in paired tumor-normal tissues, and their relationship with survival. METHODS:PLCE1 mRNA was profiled using three probes in the Affymetrix GeneChip U133 for paired tumor-normal tissues of ESCC (n = 132), gastric cardia adenocarcinoma (GCA, n = 62), and gastric noncardia adenocarcinoma (GNCA, n = 72). We used immunohistochemistry to detect PLCE1 protein on slides from tissue microarrays in paired tumor-normal tissues of ESCC (n = 303), and tumors of GCA (n = 298) and GNCA (n = 124). RESULTS:Compared with normal tissues, PLCE1 mRNA expression was significantly reduced in ESCC tumors (P = 0.03, probe_205112_at), as well as in GCA and GNCA tumors (P < 0.0001, each probe). Protein expression was nonsignificantly reduced in ESCC tumors (P = 0.51). Increased tumor-normal mRNA fold change (probe_205112_at) was associated with longer survival in ESCC (9.6 months for highest vs. lowest quartile; Ptrend = 0.02). Increased mRNA tumor-normal fold change (probe_205111_at) was associated with longer survival for GCA (10.7 months for highest quartile; Ptrend = 0.04), but not for GNCA cases (P = 0.72). Similar to mRNA, elevated tumor-normal fold change for protein in ESCC was also associated with improved survival (8.1 months for highest quartile; Ptrend = 0.04). CONCLUSIONS:Dysregulated PLCE1 mRNA expression was observed for both ESCC (one probe only) and GCA tumors, and the altered PLCE1 expression seems to be associated with cancer prognosis. IMPACT:A potential role for PLCE1 in the early detection and/or therapy of ESCC and GCA warrants further investigation.

Factors influencing the risk of recurrence in patients with esophageal carcinoma treated with surgery: A single institution analysis consisting of 1002 cases.

Project description:The aim of this study was to identify the risk of recurrence in patients with thoracic esophageal squamous cell carcinoma (TESCC) treated with curative surgery. The retrospective analysis included 1002 consecutive patients with TESCC who had been treated with curative surgery in Zhejiang Cancer Hospital, China, between 2003 and 2008. Univariate and multivariate analyses using the Kaplan-Meier method and Cox proportional hazards model, respectively, were performed to identify the independent risk factors for locoregional recurrence and all the recurrence events. The 2-and 5-year recurrence rates were 39.0 and 59.2%, respectively. More than 85% of recurrences occurred within 36 months. The variables associated with a higher rate of recurrence in the univariate analysis were gender (male), length of tumor (?5 cm), depth of invasion (deeper), lymph node metastasis (greater), histological grade (higher) and vessel involvement (positive). By multivariate analyses, gender (HR, 1.7; 95% CI, 1.2-2.5; P=0.002), depth of invasion (HR, 1.4; 95% CI, 1.2-1.6; P<0.001) and lymph node involvement (HR, 1.4; 95% CI, 1.3-1.5; P<0.001) were independent predictive factors of recurrence. Post-operative radiotherapy or chemotherapy did not significantly prolong failure-free survival (FFS), particularly in patients with early-stage disease. Information regarding the depth of primary tumor invasion and the number of lymph nodes involved may help in evaluating the recurrence risk in patients with TESCC treated with curative surgery. Further studies are required to clarify the correlation between recurrence and the different multidisciplinary treatment approaches.

Comparative genomic analysis of esophageal adenocarcinoma and squamous cell carcinoma.

Project description:Esophageal cancer ranks sixth in cancer death. To explore its genetic origins, we conducted exomic sequencing on 11 esophageal adenocarcinomas (EAC) and 12 esophageal squamous cell carcinomas (ESCC) from the United States. Interestingly, inactivating mutations of NOTCH1 were identified in 21% of ESCCs but not in EACs. There was a substantial disparity in the spectrum of mutations, with more indels in ESCCs, A:T>C:G transversions in EACs, and C:G>G:C transversions in ESCCs (P < 0.0001). Notably, NOTCH1 mutations were more frequent in North American ESCCs (11 of 53 cases) than in ESCCs from China (1 of 48 cases). A parallel analysis found that most mutations in EACs were already present in matched Barrett esophagus. These discoveries highlight key genetic differences between EACs and ESCCs and between American and Chinese ESCCs, and suggest that NOTCH1 is a tumor suppressor gene in the esophagus. Finally, we provide a genetic basis for the evolution of EACs from Barrett esophagus.

Prediagnostic plasma vitamin C and risk of gastric adenocarcinoma and esophageal squamous cell carcinoma in a Chinese population.

Project description:BACKGROUND:China has some of the highest incidence rates for gastric adenocarcinoma (GA) and esophageal squamous cell carcinoma (ESCC) in the world. Prospective studies suggested that vitamin C may reduce risks; however, associations are unclear because of limited sample size. OBJECTIVE:The objective was to examine the relation between prediagnostic plasma vitamin C and the risk of GA and ESCC. DESIGN:A case-cohort study was used to assess the association between prediagnostic plasma vitamin C and incidence of GA (n = 467) and ESCC (n = 618) in the General Population Nutrition Intervention Trial. With the use of multivariate Cox proportional hazards models, we estimated the HRs and 95% CIs. We also conducted a meta-analysis of the literature up to 1 October 2012 on the relation between circulating vitamin C and gastric cancer incidence. Two cohort studies and the current study were included to assess the body of evidence. RESULTS:For GA, each 20-?mol/L increase in plasma vitamin C was associated with a 14% decrease in risk (HR: 0.86; 95% CI: 0.76, 0.96). Compared with individuals with low plasma vitamin C concentrations (?28 ?mol/L), those with normal concentrations (>28 ?mol/L) had a 27% reduced risk of GA (HR: 0.73; 95% CI: 0.56, 0.94). No association between vitamin C concentrations and ESCC was seen. Meta-analysis showed that the risk of incident GA among those with the highest concentration of plasma vitamin C was 31% lower (random-effects-pooled-odds ratio 0.69; 95% CI: 0.54, 0.89) than those in the lowest category. CONCLUSION:Our data provide evidence that higher circulating vitamin C was associated with a reduced risk of incident GA, but no association was seen for ESCC.
