People who have been diagnosed with metastatic melanoma generally live between six and 12 months after diagnosis. Despite years of research, there are no long-term effective treatments and no cure.
In this study, researchers combined two chemotherapy drugs paclitaxel (Taxol) and carboplatin with bevacizumab, a drug that prevents the formation of new blood vessels and is used to treat cancer in combination with chemotherapy drugs.
The combination of paclitaxel (Taxol) and carboplatin has been beneficial in treating different cancers, such as metastatic lung cancer and ovarian cancer, Dr. Perez says.
Bevacizumab blocks the vascular endothelial growth factor (VEGF), a substance naturally produced in the body that stimulates the formation of new blood vessels, a process known as angiogenesis. This process is essential for tissue repair, such as wound healing, and for the overall the health of the body.
VEGF is also important for tumor growth, which depends to a large extent on the formation of new blood vessels to satisfy the increasing oxygen and nutritional needs of the growing tumor. Furthermore, there is evidence that overproduction of VEGF in response to chemotherapy may allow tumors to become more aggressive and resistant to the effects of chemotherapy by different mechanisms. Thus, it was thought that blocking VEGF with a drug like bevacizumab could facilitate the antitumor effects of chemotherapy in patients with metastatic melanoma.
Bevacizumab is a monoclonal antibody that binds VEGF and blocks its interaction with cellular receptors. This action prevents n
