Clinicopathological features and pathogenesis of esophageal small-cell carcinoma remain unclear. We hypothesized common cellular origin and pathogenesis in small-cell carcinoma of esophagus and lung associated with SOX2 overexpression and loss of Rb1. Expression of squamous-basal markers (CK5/6 and p40), glandular markers (CK18 and CEA), SOX2, and Rb1 were evaluated in 15 esophageal small-cell carcinomas, 46 poorly differentiated squamous cell carcinomas, and 88 small-cell lung carcinoma, as well as 16 embryonic esophagus...

The Glasgow Prognostic Score (GPS), neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI) are prognostic parameters for malignancies. Additionally, serum squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragments (CYFRA 21-1) are tumor markers for squamous cell carcinoma. In the present study, the prognostic importance of these markers in patients with resectable thoracic esophageal cancer was investigated. In this retrospective study, 84 enrolled patients diagnosed with resectable clinical stage I-III thoracic esophageal squamous cell carcinomas (ESCCs) underwent thoracic esophageal resection and three-field lymph node dissection at Tottori University Hospital between January 2007 and December 2013...

MicroRNAs (miRs) are small endogenous non-coding RNAs that play a vital role in carcinogenesis. miR-193a-3p has been described in multiple cancers. However, the function of miR-193a-3p in esophageal squamous cell carcinoma (ESCC) is still unclear. To explore the role of miR-193a-3p in ESCC, reverse transcription-quantitative polymerase chain reaction was used to evaluate the expression of miR-193a-3p in 48 paired ESCC and adjacent normal tissues. In addition, the impact of miR-193a-3p on cell proliferation, migration and apoptosis were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, wound scratch assay and flow cytometry, respectively...

Radiotherapy is widely used in esophageal squamous cell carcinoma (ESCC) treatment. Promoting the radiation sensitivity of cancer cells is required. Recent studies have shown that sunitinib can inhibit the growth of several cancer lines. However, few studies on the radiosensitive effect of sunitinib on ESCC cells under hypoxic conditions have been conducted. In the present study, the radiosensitive effects of sunitinib on human ESCC cells were assessed, and the underlying mechanisms were explored. ESCC cells were exposed to hypoxia and treated with sunitinib at different concentrations prior to irradiation...

Although squamous cell carcinomas and adenocarcinomas of the esophagus differ histologically, they are often lumped together in clinical trials. Genomic analysis shows that the two cancers are molecularly distinct. Esophageal adenocarcinomas are more similar to stomach adenocarcinomas, whereas esophageal squamous cell carcinomas are closer to head and neck squamous cell carcinomas.

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a leading cause of cancer-related death, and new prognostic biomarkers are urgently needed. Apoptosis-stimulating P53-binding protein 1 (ASPP1) and 2 (ASPP2) have been reported to play important roles in the development, progression, metastasis, and prognosis of cancers, but their roles in ESCC have not been elucidated. In this study, we examined the expression of ASPP1 and ASPP2 in ESCC to evaluate their prognostic values. METHODS: The protein expression of ASPP1, ASPP2, and P53 in 175 specimens of ESCC was detected using immunohistochemical staining; their expression in cancerous and noncancerous tissues was scored according to the staining intensity and the percentage of stained cells...

The morbidity and mortality of esophageal cancer is one of the highest around the world and the principal therapeutic method is radiation. Thus, searching for sensitizers with lower toxicity and higher efficiency to improve the efficacy of radiation therapy is critical essential. Our research group has previously reported that imetelstat, the thio-phosphoramidate oligonucleotide inhibitor of telomerase, can decrease cell proliferation and colony formation ability as well as increase DNA breaks induced by radiation in esophageal cancer cells...

Photodynamic therapy (PDT) has gathered much attention in the field of cancer treatment and is increasingly used as an alternative solution for esophageal cancer therapy. However, there is a constant need for improving the effectiveness and tolerability of the applied photosensitizers (PS). Here, we propose tetra-triethyleneoxysulfonyl substituted zinc phthalocyanine (ZnPc) as a promising PS for photodynamic treatment of esophageal cancer. ZnPc-induced phototoxicity was studied in two human esophageal cancer cell lines: OE-33 (adenocarcinoma) and Kyse-140 (squamous cell carcinoma)...

Numb is a protein whose asymmetric segregation during cell division determines cell fate and has numerous functions relevant to multiple fields of study, including developmental neurobiology and cancer biology. Little is known about the role of Numb in esophageal squamous cell carcinoma (ESCC), the predominant histological esophageal carcinoma in Asian populations. In this study, we focused on the expression and biological functions of Numb in the context of ESCC. From analysis of tissue microarrays with 212 patients, it was found that Numb was significantly upregulated in ESCC tissues compared to corresponding non-cancerous tissues...

We observed significant up-regulation of miR-196a in esophageal squamous cell carcinoma (ESCC) as compared with their adjacent normal tissue (p = .002). Receiver operating characteristics curve analysis confirmed the suitability of miR-196a as a potential tumor marker for diagnosis of ESCC. Furthermore, analysis of miR-196a levels in saliva samples determined an average of 27-fold up-regulations in ESCC patients compared with healthy group. Our results suggest that salivary miR-196a may be a suitable noninvasive biomarker for diagnosis of ESCC...

Cisplatin-based concurrent chemoradiotherapy for patients with unresectable, locally advanced esophageal squamous cell carcinoma (ESCC) is associated with significant toxicities that are often intolerable. Prognosis for this subgroup of patients remains poor, and new therapeutic approaches are urgently needed. We investigated the efficacy and safety of paclitaxel combined with erlotinib and concurrent radiotherapy in patients with inoperable ESCC. Erlotinib (150 mg) was administered daily for 60 days beginning at the start of radiotherapy, and paclitaxel (45 mg/m²) was administered weekly along with intensity modulated conformal radiotherapy (60 Gy in 30 fractions)...

BACKGROUND: In the early stage esophageal cancer, changes in the mucosa are subtle and pass unnoticed in endoscopic examinations using white light. To increase sensitivity, chromoscopy with Lugol's solution has been used. Technological advancements have led to the emergence of virtual methods of endoscopic chromoscopy, including narrow band imaging (NBI). NBI enhances the relief of the mucosa and the underlying vascular pattern, providing greater convenience without the risks inherent to the use of vital dye...

BACKGROUND: Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade (small cell carcinoma or large cell carcinoma) and low grade (carcinoids). OBJECTIVE: The present study aims to assess clinical and pathological neuroendocrine esophageal tumors in a single oncologic center...
