An aberrantly elevated expression of DNA polymerase ι (Pol ι) is significantly associated with poor prognosis of patients with esophageal squamous cell carcinoma (ESCC), yet the mechanisms behind this phenomenon remain obscure. Based on the RNA-Seq transcriptome and real-time PCR analysis, we identified ETS-1 as a candidate gene involved in Pol ι-mediated progression of ESCC. Wound-healing and ...

Esophageal papillomatosis is a very rare condition that is believed to have a benign clinical course. Recent reports underscore the potential development of a malignancy in association with squamous papillomatosis of the esophagus. A case of esophageal papillomatosis complicated by the development of esophageal invasive squamous cell carcinoma diagnosed after esophagectomy, despite multiple non...

Owing to recent advances in diagnostic and surgical techniques for cancer, a patient diagnosed with two or more neoplasms is not rare. We report on the case of a 58-year-old male with multiple primary malignant neoplasms, who suffered from three histological types of malignant neoplasm in six organs, namely the glottis, renal pelvis, urinary bladder, oral floor, prostate, and esophagus in chron...

BACKGROUND/AIMS Esophageal squamous cell carcinoma is a common malignant tumor in recent years, and the key for improving the survival rate is early diagnosis and treatment. Computed virtual chromoendoscopy with the Fujinon intelligent color enhancement (FICE) system was reported to improve visualization of neoplastic and non-neoplastic lesions in gastroscopy and colonoscopy. The purpose of thi...

BACKGROUND Recently, attention has been directed to concurrent chemoradiotherapy (CRT) for the treatment of squamous cell carcinoma of the esophagus with regard to efficacy, quality of life and functional preservation, and survival periods comparable to those after standard surgical therapy have been reported in responders to CRT. However, there are some non-responders to CRT, and the predictio...

Background: Esophageal carcinoma is one of the most lethal gastrointestinal (GI) malignant tumors worldwide.  The disease is known to have a high incidence in northern Iran; however, its condition in the South is not much clear. Objective: In this retrospective study we investigated the epidemiology and time trends of esophageal carcinoma in Fars Province, South of Iran. Methods: In a retrospec...

verrucous carcinoma is a unique clinical and pathological entity which has been recognised in the recent years. it is a variant of well-differentiated squamous cell carcinoma which may occur in the larynx; other anatomic locations such as: the oral cavity, anogenital region, and skin may be involved. it accounts for 1-2% of all laryngeal cancers. the clinical, histopathological and biologic fea...
