The aim of the present study was to accurately evaluate the association of Sox2 expression with the survival of patients with digestive tract cancers. Relevant literatures were identified by comprehensively searching databases including the Pubmed, Embase, CBMdisc, and Wanfang (up to October 2014). A meta-analysis was performed to clarify the association between Sox2 expression and overall survival or clinicopathological parameters of patients with digestive tract cancers (esophageal, gastric, and colorectal cancers). The results showed a significant association between high Sox2 expression and poor overall survival in patients with digestive tract carcinomas (HR=1.55, 95% CI=1.04-2.31), especially for patients with esophageal cancer (HR=2.04, 95%CI=1.30-3.22), colorectal cancer (HR=1.40, 95% CI=1.04-1.89), and digestive tract adenocarcinoma (HR=1.80, 95% CI=1.12-2.89), for Europeans (HR=1.98, 95% CI=1.44-2.71) or patients who did not receive neoadjuvant treatment (HR=1.73, 95% CI=1.10-2.72). Furthermore, Sox2 over-expression was highly correlated with vascular invasion (OR=1.86, 95% CI=1.25-2.77) and poor differentiation (OR=1.88, 95% CI=1.14-3.08), especially in esophageal and colorectal cancers. In conclusion, Sox2 expression may serve as a novel prognostic factor for patients with digestive tract cancers. Over-expression of Sox2 that is correlated with vascular invasion and poor differentiation suggests poor outcomes of patients with digestive tract cancers.

BACKGROUND/AIMS: The efficacy of surveillance for esophageal squamous cell neoplasia (ESCN) in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Our study aimed to provide clinical data concerning the necessity of surveillance for detecting early ESCN in patients with HNSCC. METHODS: We retrospectively reviewed the data from 714 patients who were pathologically confirmed as having HNSCC (n=236 oral cavity cancers, 137 oropharyngeal cancers, 87 hypopharyngeal cancers, and 254 laryngeal cancers). RESULTS: Of 714 patients, during a median follow-up of 31 months, 48 ESCNs (37 synchronous and 11 metachronous) were detected in 36 patients (5%). Fifteen synchronous lesions (40.3%) were early ESCN, whereas nine metachronous lesions (81.8%) were early ESCN. The 3-year survival rates of HNSCC only and HNSCC combined with ESCN were 71.2% and 48.2%, respectively (p<0.001). Among 36 patients with ESCN, the 3-year survival rates for early and advanced ESCN were 77.7% and 21.7%, respectively (p=0.01). In the multivariate analysis, alcohol consumption and hypopharyngeal cancer were significant factors associated with the development of ESCN. CONCLUSIONS: HNSCC patients with early ESCN were similar in prognosis with patients without ESCN, in contrast to patients with advanced ESCN. Therefore, surveillance for the early detection of ESCN in patients with HNSCC, especially in alcohol drinkers and those with hypopharyngeal cancer, is warranted.

A 61-year-old man with no history of malignancy presented with a rapidly expanding left periorbital mass, first noticed one month prior to presentation. The mass was firm, and a pus-like discharge drained spontaneously from the center of the lesion. A biopsy was performed, and histopathology confirmed squamous cell carcinoma. Systemic evaluation revealed that the patient had a primary esophageal squamous cell carcinoma with multiple metastases. The prognosis of orbital metastasis is generally poor, and this patient expired after one month of conservative treatment.

OBJECTIVEThis study was to review the clinical features, diagnosis, treatment, and prognosis of esophageal adenosquamous carcinoma (ASC).

METHODSClinical data of 22 patients with pathologically confirmed esophageal ASC, treated in the Cancer Center of Sun Yat-sen University from May 1988 to April 2006, were retrospectively analyzed. The survival analysis was performed using Kaplan-Meier method.

RESULTSOf 4208 patients diagnosed as esophageal cancer during the same time in our center, only 22 had esophageal ASC, accounted for 0.52%. The median age of the 22 cases was 60 years (range, 42 to 69 years). Esophageal ASC showed similar clinical symptoms, radiological and endoscopic features to esophageal squamous cell carcinoma (ESCC). Nineteen cases were preoperatively misdiagnosed as ESCC by endoscopic biopsy. Among the 22 patients, 16 were treated by surgery alone, 3 by surgery plus postoperative radiotherapy, and the remaining 3 by radiotherapy, sequential chemoradiotherapy and concurrent chemoradiotherapy, each in one case, respectively. The overall 1-, 3- and 5-year survival rates were 67.6%, 33.8% and 18.1%, respectively, with a median survival time of 24.5 months.

CONCLUSIONEsophageal adenosquamous carcinoma is a rare esophageal disease and prone to be misdiagnosed as esophageal squamous cell carcinoma. Initial surgical treatment combined with other therapies is suggested. The prognosis of esophageal adenosquamous carcinoma has not yet been well established.

OBJECTIVETo investigate the histopathological features of basaloid squamous cell carcinoma of the esophagus, and to explore the ways of its diagnosis, differential diagnosis and treatment.

METHODSThe clinical data and pathological features of 23 cases of esophageal basaloid squamous cell carcinoma were reviewed and analyzed retrospectively.

RESULTSThe tumors were mainly located at the middle third segment of the esophagus. The 1-,2- and 3-year survival rates were 60.9%, 21.7% and 0, respectively.

CONCLUSIONThe basaloid squamous cell carcinoma of the esophagus is highly malignant with poor prognosis. Radical resection combined with radiotherapy and chemotherapy is required.
