Abstract Background p53 isoform Δ133p53 is directly transactivated by p53 and antagonizes p53 activities in cancer progression. However, its correlation with prognosis and cancer recurrence in esophageal squamous cell carcinoma (ESCC) is still unclear.Methods Expression of Δ133p53 and Δ133p53/full-length p53 (FLp53) in tissues and serums of 180 ESCC patients was evaluated using qRT-PCR.Results Tissue Δ133p53 expression and Δ133p53/FLp53 ratio were significantly increased in ESCC tissue compared with adjacent normal tissue. Pre-operative Δ133p53 expression and Δ133p53/FLp53 ratio in tissue or serum samples were positively associated with TNM stage and post-operative recurrence. Kaplan-Meier curve and multivariate cox regression analyses revealed that the tissue and serum Δ133p53/FLp53 ratio (cutoff value: 2.9160) were independent prognostic factors for overall survival (OS) and progression-free survival (PFS) in ESCC patients, and showed no statistical difference in receiver-operating characteristic (ROC) curve analysis, while serum Δ133p53 showed no significant prognostic value. More importantly, the serum Δ133p53/FLp53 ratio in ESCC patients was significantly decreased within 72 h post tumor resection and patients with a consistently high serum Δ133p53/FLp53 ratio (≥ 2.9160) had higher recurrence rates than those with consistently low ratio values. In addition, dynamic detection in each follow-up timepoint showed that serum Δ133p53/FLp53 ratios were higher than 2.9160 upon recurrence, and they even increased prior to radiologic progression.Conclusion The serum Δ133p53/FLp53 ratio can be a novel predictor for survival outcome and may serve as a real-time parameter for monitoring recurrence in ESCC patients after surgery.

Abstract Background To investigate the expression of PD-L1(programmed death-ligand 1)in patients with esophageal squamous cell carcinoma (ESCC) and its clinical significance. Methods The tissue expression of PD-L1 protein in 139 cases of ESCC and 50 adjacent non-malignant epithelial tissues (> 5 cm from the tumor resection margins) were identified by immunohistochemical staining. Subsequently, the relationship between expression and the observed clinical characteristics was analyzed. Results The positive expression rate of PD-L1 protein was increased in tumor tissues compared to that of adjacent noncancerous mucosa tissues (40.3% vs. 22.0%, P < 0.05). The findings also indicated that PD-L1 protein expression had no significant correlation with age, gender, tumor location, differentiation and lymph node (N) status (P > 0.05). The 91 months follow-up Kaplan-Meier survival analysis showed that patients in positively expressed PD-L1 group experienced a lower survival rate compared to their negatively expressed PD-L1 counterparts (32.1% vs. 48.2%, P < 0.05). The COX regression analysis results suggested that PD-L1 represented an independent prognosis factor for ESCC. Conclusions The findings indicated that PD-L1 plays an important role in the progression of ESCC and might represent a potential therapeutic and prognostic target for ESCC patients.

Increasing evidence indicated that microRNAs served dominant roles in carcinogenesis and cancer progression by targeting potential downstream genes. In our study, we found that miR-527 was an upregulated expression in human esophageal squamous cell carcinoma (ESCC) cells and tissues. Furthermore, overexpression of miR-527 promoted cell proliferation and colony formation, enhanced anchorage-independent growth ability, and contributed to cell cycle. In addition, protein phosphatase 2 (PHLPP2) was identified as the direct downstream target gene of miR-527 and was confirmed by luciferase gene reporter assay. In summary, we concluded that miR-527 acted as an oncogenic microRNA in ESCC development by directly targeting PHLPP2 might be a novel therapeutic target for the treatment of ESCC.

Abstract Background Although the incidence of lymph node (LN) metastasis (LNM) along the left gastric artery is high, its relationship with the prognosis in postoperative patients with esophageal squamous cell carcinoma (ESCC) is rarely reported. This study clarified the prognostic impact of LNM along the left gastric artery in postoperative patients with ESCC. Methods This study assessed data of 1521 patients with ESCC who underwent esophagectomy at the Sun Yat-sen University Cancer Center between March 1992 and March 2012. A chi-squared test and Mann-Whitney U test were used to explore the preliminary correlation between clinical factors and LNM along the left gastric artery. Univariate and multivariate Cox regression analyses were used to assess whether LNM along the left gastric artery was an independent predictor of overall survival. Kaplan–Meier analysis and the log-rank test were used to present a classifying effect based on LN status. Results LNM was observed in 598 patients (39.3%) and was found along the branches of the left gastric artery in 256 patients (16.8%). The patients were classified into two groups based on the presence of LNM along the left gastric artery. Patients without LNM along the left gastric artery had better cancer-specific survival than those with positive LNs (P <  0.001). Conclusions This study indicated that LNM along the left gastric artery was an important independent prognostic factor for long-term survival among ESCC patients (P = 0.011).

The hemoglobin, albumin, lymphocyte, and platelet (HALP) score has been confirmed as a prognostic factor in several types of cancers. The current study aimed to assess the prognostic value of preoperative HALP score, an inflammatory and nutritional based score, in predicting cancer-specific survival (CSS) in resectable patients undergoing curative resection for esophageal squamous cell carcinoma (ESCC). The clinical data of 355 consecutive patients with ESCC who underwent curative resection were retrospectively conducted and analyzed. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value for preoperative HALP. The areas under the curve (AUC) for preoperative HALP and other variables were calculated and compared. Cox regression analyses and Kaplan-Meier methods were used to identify the factors associated with CSS. According to the ROC curve, the optimal cut-off value for preoperative HALP was 31.8. The 5-year CSS for preoperative HALP low (≤31.8) and high (>31.8) was 15.1% and 47.5%, respectively (p<0.001). Preoperative HALP had reliable abilities to predict CSS in resectable ESCC patients in any stage or gender, according to the subgroup analysis based on the patients' cancer stage and gender. Multivariate analyses confirmed that preoperative HALP was an independent prognostic score regarding CSS in patients with resectable ESCC (p<0.001). This study confirmed that the preoperative HALP score could be regarded as a potential independent prognostic factor for CSS in patients with resectable ESCC.

Abstract Background Several studies have suggested an association between poor oral health and esophageal squamous cell carcinoma (ESCC). We conduct this study to further examine the association between oral hygiene and ESCC risk in Linxian, the high risk area of China. Methods We recruit 29,553 healthy and 3318 esophageal squamous dysplasia participants aged between 40 and 69 in 1985 and then followed up until April, 2015. Basic characteristics were collected and oral related diseases were examined by trained doctors. Cox regression models were used to calculate hazard rations (HRs) and 95% confidence intervals (CIs). Results In general group, 2577 participants’ dead for ESCC and the cumulative rate of ESCC death was 12.9%. Teeth loss more than 20, before age of 40, bleeding of teeth, chapped lips, oral leukoplakia were significantly associated with risk of death from ESCC, and with 1.28 (95% CI: 1.18–1.38), 1.12 (95% CI: 1.03–1.23), 1.28 (95% CI: 1.13–1.45), 1.14 (95% CI: 1.04–1.25), 1.23 (95% CI: 1.12–1.35) fold increased risk of death from ESCC respectively in models adjusted for potential confounders. In dysplasia group, 540 participants’ dead for ESCC and the cumulative rate was 24.7%. Those who loss teeth more than 20, before age of 40, bleeding of teeth, have 1.24 (95% CI: 1.02–1.51), 1.25 (95%CI: 1.02–1.52), 1.35(95%CI: 1.06–1.70) fold increased risk after adjustment. Association between chapped lips and ESCC death was not found. Conclusion Severe teeth loss, early age teeth loss and teeth bleeding were associated with ESCC death and excess risk increased as dysplasia occurred. Chapped lips loss association with ESCC death in dysplasia group, it may reveals that it react before dysplasia change. Further studies are warranted to find the mechanism association and improvements of protecting oral health should be done. Disclosure All authors have declared no conflicts of interest.

e15675 Background: Esophageal squamous cell carcinoma (ESCC) is one of the most common fatal cancers worldwide due to the lack of an early disease screening strategy. Identification of diagnostic markers will greatly improve the morbid outcome. Dickkopf 1 (Dkk1) is a secreted antagonist of Wnt signaling pathway, an important pathway in tumorigenesis. The expressions of Dkk1 seem to be tumor-specific: reduced expressions have been seen in colorectal cancer, but elevated levels were reported for hepatoblastomas. In ESCC, the situation is less clear, for both elevation and reduction of Dkk1 were reported. The serum concentrations of Dkk1 have also been shown to be higher in ESCC patients’ sera in one study. In view of the varied outcome from Dkk1 tissue expressions and the scarce reports on Dkk1 serum concentration from ESCC patients, we therefore sought to determine the tissue expression and serum concentrations of Dkk1 as our first step to evaluate the potential of Dkk1 as a diagnostic marker for ESCC. Methods: The expression levels of Dkk1 in ten ESCC tumor and adjacent non-tumor tissues were examined by Western blot. Serum Dkk1 level of 168 samples were quantified in a double-blind fashion by ELISA (Dkk1 Duoset ELISA development kit from R & D Systems, Minneapolis, MN). To ensure that the serum Dkk1 detection was not affected by autoantibodies against Dkk1 present in sera, we also measured serum Dkk1 autoantibody levels by ELISA with modifications to the ELISA kit. Results: Seven out of ten of the tumors showed elevated Dkk1 level, while only two out of ten of the control normal tissue showed elevation. Surprisingly, after decoding of our serum samples into 80 patients and 88 normal controls, we found that Dkk1 level was significantly lower in patient sera (2.99ng/ml) than the normal samples (5.32ng/ml) (p=0.0001; t-test). The measurements were not obscured by the presence of Dkk1 autoantibodies, as they were not different between patient and control samples. Conclusions: Contrary to previous published results, we found Dkk1 is suppressed in patient sera, and thus our result undermines the potential of serum Dkk1 level as a predictive marker for ESCC. Further investigations will be needed to explain the discrepancies between the studies. No significant financial relationships to disclose.

Aims. We sought to determine the relationship between CADM1/TSLC1 expression and clinicopathological characteristics in patients with esophageal squamous cell carcinoma (ESCC) and the correlation with survival.Materials and Methods. Two hundred and ninety-three ESCC tissues and paired adjacent normal esophageal tissues were immunohistochemically assessed in this study. The association of CADM1/TSLC1 with clinicopathological parameters, as well as disease-free survival (DFS) and overall survival (OS), was determined based on the Kaplan-Meier method and Cox regression models.Results. CADM1/TSLC1 was detected in 236 (80.5%) tumor tissues and 19 (8.0%) paired adjacent normal esophageal tissues. Decreased CADM1/TSLC1 expression was correlated with more advanced histological grade. CADM1/TSLC1 negative tumors were more frequently observed in male cases than in female cases. DFS and OS in the CADM1/TSLC1 negative group were significantly shorter than those in the positive group, particularly in male patients with ESCC.Conclusion. Loss or reduction of CADM1/TSLC1 expression is associated with more advanced histological grade and predicts early recurrence and short survival duration. Thus, loss of CADM1/TSLC1 could be a prognostic factor that can be used to assess the risk of recurrence and survival.
