Abstract Background The role of radiotherapy for cT4bNanyM0 esophageal squamous cell carcinoma (ESqCC) is relatively unclear, with both chemotherapy (C/T) alone and definitive concurrent chemoradiotherapy (dCCRT) being treatment options in the current guidelines. We aimed to compare the survival of dCCRT versus C/T for these patients via a population-based approach. Methods Eligible cT4b ESqCC patients diagnosed between 2011 and 2017 were identified via the Taiwan Cancer Registry. We used propensity score (PS) weighting to balance the observable potential confounders between groups. The hazard ratio (HR) of death and incidence of esophageal cancer mortality (IECM) were compared between dCCRT and C/T. We also evaluated OS in subgroups of either low or standard radiotherapy doses. Results Our primary analysis consisted of 247 patients in whom covariates were well balanced after PS weighing. The HR for death when dCCRT was compared with C/T was 0.36 (95% confidence interval 0.24–0.53, P < 0.001). Similar results were found for IECM. Statistical significance was only observed in the standard RT dose but not in the low dose in subgroup analyses. Conclusions In this population-based nonrandomized study of cT4bNanyM0 ESqCC patients from Asia (Taiwan), we found that the use of radiotherapy with chemotherapy was associated with better overall survival than chemotherapy alone. Further studies (especially RCTs) are needed to confirm our findings.

Abstract Background Recent studies have reported important roles for chloride intracellular channel 1 (CLIC1) in various cancers; however, its involvement in esophageal squamous cell carcinoma (ESCC) remains unclear. The aim of the present study was to investigate the role of CLIC1 in human ESCC. Methods CLIC1 expression in human ESCC cell lines was analyzed by Western blotting. Knockdown experiments were conducted with CLIC1 siRNA, and their effects on cell proliferation, the cell cycle, apoptosis, migration, and invasion were analyzed. The gene expression profiles of cells were analyzed using a microarray analysis. An immunohistochemical analysis was performed on 61 primary tumor samples obtained from ESCC patients who underwent esophagectomy. Results ESCC cells strongly expressed CLIC1. The depletion of CLIC1 using siRNA inhibited cell proliferation, induced apoptosis, and promoted cell migration and invasion. The results of the microarray analysis revealed that the depletion of CLIC1 regulated apoptosis via the TLR2/JNK pathway. Immunohistochemistry showed that CLIC1 was present in the cytoplasm of carcinoma cells, and that the very strong or very weak expression of CLIC1 was an independent poor prognostic factor. Conclusion The present results suggest that the very strong expression of CLIC1 enhances tumor survival, while its very weak expression promotes cellular movement. The present study provides an insight into the role of CLIC1 as a switch among tumor behaviors in ESCC. Disclosure All authors have declared no conflicts of interest.

Background Recent studies have shown that long noncoding RNA (IncRNA) gastric carcinoma highly expressed transcript 1 (GHET1) was involved in the progression of tumors. However, the role of GHET1 in esophageal squamous cell carcinoma (ESCC) remains unclear. Methods The expression of IncRNA GHET1 was examined in 55 paired ESCC tissues and adjacent nontumor tissues. Molecular and cellular techniques were used to explore the role of GHET1 on ESCC cells. Results Our data showed that GHET1 expression was significantly increased in ESCC tissues and cell lines. High GHET1 expression in ESCC tissues was significantly associated with poor differentiation, advanced tumor nodes metastasis stage, and lymph node metastasis. GHET1 showed high sensitivity and specificity for diagnosing ESCC. Our data from in vitro assays showed that GHET1 inhibition suppressed ESCC cells proliferation, migration, and invasion, and induced cells apoptosis. Furthermore, western blot showed that GHET1 inhibition significantly decreased the expression of vimentin and N-cadherin while it increased the expression of E-cadherin. Conclusions Our study indicates that GHET1 acts as an oncogene in ESCC and may represent a novel therapeutic target for the treatment of ESCC patients.
