Esophageal cancer is one of the most common type of malignancies. Telomerase activity, which is absent or weakly detected in the majority of human somatic cells, is elevated in esophageal cancer. Although azidothymidine (AZT), a reverse transcriptase inhibitor, has been utilized as a treatment for tumors, its role in treating esophageal cancer has not been confirmed. The aim of the present stud...

Human esophageal cancer is one of the most common causes of cancer death in China. Tumor recurrence and metastasis are the main reasons for the failure in cancer treatments. Increasing evidences indicated that cancer stem cell (CSC) are thought to be responsible for tumor initiation and progression. Therefore, therapies targeting cancer stem cells offer a promising strategy for cancer treatment...

Background & Aims: Esophageal and gastric cancers are among prevalent cancers in the world and it is believed that nitrate and nitrite contaminations of drinking water are important factors in increasing the risk of these cancers. This study was designed to determine the correlations between these factors and upper gastrointestinal cancers. Methods: In this ecologic study, mean concentrations o...

The overexpression of ATP-binding cassette (ABC) transporters confers multidrug resistance (MDR) to tumor cells. ABCG2 is a member of the ABC superfamily. The present study aimed to investigate the correlation between ABCG2 expression and the MDR of esophageal cancer and to estimate the therapeutic benefit of downregulating ABCG2 expression and reversing chemoresistance in esophageal cells usin...

 Abstract Background: Esophageal cancer is one of the major malignancies, with various epidemiological aspects in recent years in developing countries, including increased prevalence and variations of pathologic patterns. This may be due to increasing rates of Barrett’s esophagus, gastroesophageal reflux, smoking and obesity. This study was performed from 1991 to 2005 in order to evaluate vario...

BACKGROUND Chemo-radiotherapy, a combination of chemotherapy and radiotherapy, is the most frequent treatment for patients with esophageal cancer. In the process of radiotherapy, the radiosensitive cancer will become a radio-resistant one. METHODS In order to detect the chemotherapeutic drug sensitivity in radio-resistant cancer cells and improve the therapy efficiency, we firstly established...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

Younger patients (aged <30 years) presenting with esophageal cancer are rare. Bone marrow transplantation offers a curative therapy in patients with malignant and nonmalignant lymphohematopoietic diseases and other disorders. However, one important late complication in transplantation survivors is the development of secondary malignancies including solid tumors. Although some solid cancers have...
