Molecular biology of upper gastrointestinal malignancies.

Abstract:

:While cancers of the upper gastrointestinal tract are related by location, they have distinct clinical and molecular characteristics. This review will focus on the molecular biology of esophageal adenocarcinoma (EAC) of which alterations in p53, overexpression of cyclin D1, loss of p16, and aneuploidy have been best characterized. Key similarities and differences, when compared to esophageal squamous cell carcinoma (ESCC), gastric adenocarcinoma (GC), and adenocarcinoma of the gastric cardia (AGC), will also be highlighted. Currently, malignancies of the upper gastrointestinal tract are often diagnosed at an advanced stage and are generally associated with a poor patient prognosis. With an improved understanding of the molecular biology of these tumors, there is hope that new targets for diagnosis, chemoprevention, and therapy will be developed.

  • Profiling the safety and tolerability of bisphosphonates.

    abstract::Because patients with metastatic bone disease suffer a significant burden from their illness and from anticancer treatments, it is therefore important to minimize the side effects of bisphosphonates. The intravenous bisphosphonates, zoledronic acid and pamidronate, have tolerability issues that include a flu-like synd...
