Miraculous pembrolizumab
When former US President Jimmy Carter last year announced that its advanced skin cancer apparently retreated, many of Carter's supporters saw it as a miracle. Havel said doctors described it as key to the success of one of the drugs that had been deployed - pembrolizumab. This active substance was, along with several other approved by the US Food and Drug Administration (FDA) for use only in recent years.
Cancer on the horizon? Drain viruses!
The active compounds of budding waves on which now carries the treatment of melanoma can be divided into two groups. The first group includes active immunotherapy:
ipilimumab,
nivolumab,
pembrolizumab,
peginterferon alfa-2b,
talimogen laherparepvec.
The first three substances work by releasing a brake mechanism of the immune system, thus allowing it to better fight the tumor cells. The latter change cleverly uses viral particles to destroy tumor. The dose of the drug, which is a modified herpes virus is injected directly into the tumor site. Here, the virus attacks the cancer cells and multiply therein until cells crowded viral particles, will not break and dies. Ingenious, is not it?
Targeted genetic mutations
The second group of drugs belonging to the family of targeted drugs in our country, also known as biologic drugs. What is the objective against which it is directed? Genetic mutations occurring in some types of melanomas. On their focus as the substances:
cobimetinib,
dabrafenib,
trametinib,
vemurafenib.

This is a remarkable progress since earlier drugs used in chemotherapy occupied in about one man out of ten. Not all patients with melanoma in an advanced stage of the new treatment will help, but for many it can for a considerable time to keep the disease at bay and prolong active life. As with any treatment, even newly tested drugs may occur side effects. Among the FDA include symptoms similar to flu or herpes development.
