Targeted Cancer Therapies

molecularly targeted therapy 

In cancer, a type of treatment that uses drugs or other substances to target specific molecules involved in the growth and spread of cancer cells. Blocking these molecules may kill cancer cells or may keep cancer cells from growing or spreading. Molecularly targeted therapy may cause less harm to normal cells and may have fewer side effects than other types of cancer treatment.

There are 2 main types of targeted therapy:

  • Monoclonal antibodies. Drugs called gmonoclonal antibodiesh (the drug name ending with –mab) block a specific target on the outside of cancer cells. Or the target might be in the area around the cancer. We cannot expect much efficacy. You usually get these drugs intravenously (IV).
  • Small-molecule drugs. Drugs called gsmall-molecule drugsh can block the process that helps cancer cells multiply and spread. These drugs are usually taken as pills. Angiogenesis inhibitors are an example of this type of targeted therapy. These drugs keep tissue around the tumor from making blood vessels. Angiogenesis is the name for making new blood vessels. A tumor needs blood vessels to bring it nutrients. The nutrients help it grow and spread. Anti-angiogenesis therapies starve the tumor by keeping new blood vessels from developing. I recommend thalidomide with multiple actions.
