Esophageal cancer is one of the most aggressive malignancies gastrointestinal tract, characterized by high malignancy potential and poor prognosis. Surgical treatment standard for localized esophageal cancer, but results only surgery locally advanced tumors remain unsatisfactory. The use neoadjuvant chemotherapy, as well chemoradiation therapy, leads to a downstaging tumor, improves its resecta...

BACKGROUND AND AIMS Endoscopic Interventional Treatment is of little trauma and less complications in the treatment of esophageal tumor and leads to faster recovery and fewer days of hospitalization. This study was aimed to investigate the safety and efficacy of endoscopic interventional therapy for huge esophageal tumor arising in the muscularis propria. METHODS The patient was treated by su...

background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...

in this archival analysis of genetic & protein alterations in the p53 tumor suppressor gene, we used immunohistochemical methods for detection of these alterations. the tumor series includes: 61 paraffin embedded esophageal squamous cell carcinoma from a high incidence (ethnic) & a non-high incidence regions in iran.

Esophageal cancer is one of most common malignancies. Cancer stem cells (CSC) are considered to be resistant to chemotherapy and radiotherapy, which might be associated with the recurrence of the tumor after treatment. To find the therapeutic procedures targeting CSCs, the different methods have been used to identify the esophageal CSC-related genes and surface markers. The esophageal CSCs were...

the current challenges in the management of esophageal cancer are to obtain a better understanding of underlying molecular alterations to provide new treatment options. we studied the p53 and bcl-2 protein expression in esophageal carcinomas to correlate molecular alterations with clinicopathological findings. tissue samples of 37 patients with advanced esophageal carcinoma were analyzed by imm...

A functional linkage of the structurally unrelated receptors HER2 and CXCR4 has been suggested for breast cancer but has not been evaluated for esophageal carcinoma. The inhibition of HER2 leads to a reduction of primary tumor growth and metastases in an orthotopic model of esophageal carcinoma. The chemokine receptor CXCR4 has been implicated in metastatic dissemination of various tumors and c...

in this study esophageal resection and radiotherapy methods were compared in relation to the patients suffering from esophageal cancer. three hundred and fifty-four patients with squamous cell carcinoma of esophagus who had been hospitalized in the cancer institute of the imam khomeini hospital, tehran, during 1981-1985 were followed up through march 21st, 1987. based on the findings, patients ...

leiomyoma of the esophagus is rare, but it is the commonest among the benigh tumors of the esophagus. among 95 cases of esophageal tumors, there was just 4 cases of leiomyoma (3 were females and 1 was male) and this is contrary to the reports already published. main symptoms of esophageal leiomyoma include: disphagia, pain and hematemesis from the above mentioned cases 1 tumor was in the thorac...

We used TaqMan PCR to detect quantitative anomalies of tumor markers in both tumor and serum DNA from esophageal cancer patients. We demonstrated the potential of this methodology by detecting erbB-2 amplifications in a plurality of esophageal tumor samples. These amplifications were corroborated by Southern blots. We then showed the potential of this methodology to detect quantitative anomalie...
