Immunotherapy boosts the body’s immune system to fight the cancer. This treatment is also called biological therapy.
The most common immunotherapy drug for Kaposi’s sarcoma (KS) is interferon alpha. These drugs stop viruses from copying themselves. They also trigger the immune system to fight the virus.
You take an interferon by injection 3 to 7 times a week. It is most effective if you have lesions just on your skin and your immune system is not too suppressed. Your doctor may not recommend this treatment if your CD4 cell count is less than 200 because it can be toxic for people with low CD4 counts.
