A potential targets for the prevention or treatment of esophageal carcinoma
October 29, 2008Expression of Livin in fresh esophageal cancer tissues was detected by immunohistochemistry (IHC), Western blotting and reverse transcriptase-polymerase chain reaction (RT-PCR), VEGF by Its correlation Western blotting and RT-PCR. Livin positivity was also significantly correlated with tumor stages, increasing with tumor progression. Expression of Livin and VEGF increased with the process of esophageal carcinoma. In the fourth clinical stage, expression of Livin and VEGF was the most significant. Expression of Livin was positive correlation with VEGF. Over-expression of Livin and VEGF contributes to the pathogenesis of esophageal carcinoma.
A research article to be published on October 7, 2008 in the World Journal of Gastroenterology addresses this question. The research team led by Professor
Ren GS Cancer Institute of Chiongqing Medical University used molecular biology technology to investigate the role of Livin and VEGF in human esophageal carcinoma and analyze its relationship with clinical stages.
In the present study, authors investigated expression of Livin in human esophageal carcinoma and analyze its relationship with clinical stages. The results showed that Livin positivity was also significantly correlated with tumor stages, increasing with tumor progression. Expression of Livin increased with the process of esophageal carcinoma. In the fourth clinical stage, expression of Livin was the most significant. The results showed that VEGF positivity was also significantly correlated with tumor stages, increasing with tumor progression. Expression of VEGF increased with the process of esophageal carcinoma. In the fourth clinical stage, expression of VEGF was the most significant.
Taken together, over-expression of Livin and VEGF contributes to the pathogenesis of esophageal carcinoma. Level of VEGF has positive correlation with Livin. The hypothesis has been made that Livin and VEGF played such an inter-enhancement role in the progress of esophageal carcinoma. Inhibitors of Livin and VEGF may be potential targets for the prevention or treatment of human esophageal carcinoma.

Molecular imaging technology used in gastric cancer
Modern cancer care is critically dependent on imaging technologies, which are used to detect early tumors and guide their therapy or surgery. Molecular imaging technologies provide information about the functional or metabolic characteristics of malignancies, tumor stage and therapeutical response, and tumor recurrence; whereas conventional imaging technologies predominantly assess the tumor's anatomical or morphologic features including its size, density, shape, etc.
Age, burden, divorce and heavy tea consumption are significant risk factors for erosive esophagitis
Gastroesophageal reflux disease (GERD) is a common disorder with a high incidence rate in adults of 10 - 38%. The diagnosis and treatment of GERD are therefore important because the disease, in addition to the highly disturbing typical symptoms, has a series of known consequences.

Atlas of Minimally Invasive Surgery in Esophageal Carcinoma by Shailesh Puntambekar (Editor), Miguel A. Cuesta (Editor) The main aim of this book is standardization of the procedure with stress on simplification and ease of performing the surgery. In oncology, the principles and steps of an operative procedure should remain the same; though the modality may change, be it either open surgery or laparoscopy. Thus, in this book the patient position and procedural steps are devised to mimic open surgery as far as possible. This makes it easier for the oesophageal surgeon performing surgeries by the open technique to get converted into a thoracoscopic laparoscopic surgeon. This atlas will be a step by step guide for a surgeon who wishes to perform laparoscopy with more than 500 operative photographs. Additional value has been two DVD’s of the procedure and added chapters such as anaesthesia, stapler, world... | |
