background: clinical and epidemiological variation was seen between the colon cancer (cc) and rectum cancer (rc). so, there is not so much data available about the epidemiological and clinicopathological differences and prognostic factors regarding to cc and cr in iran, we aimed to perform this study. methods: all cases of cc and rc referred to oncology and gastroenterology wards of taleghani g...

Image-enhanced endoscopy is helpful for screening of a second primary neoplasm in patients with esophageal and head and neck cancer. The purpose of this meta-analysis was to determine the diagnostic efficacy of white-light imaging (WLI), narrow band imaging (NBI), and Lugol chromoendoscopy for second primary neoplasm detection. A review of the PubMed/Cochrane databases up to May 2014 was perfor...

Recent advances in endoscopic techniques, including magnifying endoscopy and image-enhanced endoscopy, have increased the detection rate of early-stage esophageal squamous cell neoplasm (ESCN). Treatment options for superficial ESCN have expanded, with endoscopic resection considered the standard treatment. Several studies have reported favorable clinical outcomes of endoscopic resection for su...

BACKGROUND/AIMS Endoscopic resection (ER) of superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ER for SEN to determine its feasibility and effectiveness. METHODS Subjects who underwent ER for SEN at Asan Medical Center between December 1996 and December 2010 were eligible. The clinical features of patients and tumors, histopat...

abstract background: esophageal replacement is indicated in certain circumstances including long gap esophageal atresia, severe strictures due to gastro-esophageal reflux (ger) and caustic burns. we analyzed our results of 18 patients who underwent esophageal replacement in our university hospital. methods: we reviewed esophageal replacements carried out in our department between june 1996 and ...

Primary hepatic angiosarcoma is a rare and rapidly fatal disease. We present the highly unusual identification of this lesion five years after the initial clinical presentation.In 2003, a 32-year-old man presented with abdominal pain, tachycardia, and evidence of hemorrhage. A CT scan showed a hepatic mass with intralesional hemorrhage, intraperitoneal blood, and splenomegaly. The patient was s...

BACKGROUND Gastrointestinal neoplasm (GIN) is the most common neoplasm in China. The global chromatin organizer SATB1 (special AT-rich sequence binding protein 1) is aberrantly expressed in multiple human neoplasms. We conducted this meta-analysis to investigate whether the invasion and metastasis of GIN correlates with SATB1 levels in tumor tissues in Chinese patients. MATERIALS AND METHODS ...

Despite the fact that the thyroid is a highly vascularized organ, clinically significant metastatic spread to the thyroid is considered uncommon. Hypothyroidism due to these metastases seldom occurs. A 68-year-old female patient came to our department because of rapid enlargement of the lower anterior part of the neck, which developed within 2 months. She had a history of poorly differentiated ...

The authors present the case of a primitive small cell esophageal carcinoma. It is a rare and biologically aggressive neoplasm which occurs mainly in the elder male. The case observed concerns a 69 year old female treated with surgical therapy consisting in esophagectomy and intrathoracic esophagealgastrictype plasty. Diagnostic problems either histological or immunohistochemical and the choice...
