How does immunotherapy work in melanoma?

In some people, T-cells can recognise and destroy melanoma cells. But a protein on the T-cells stops this happening. Ipilimumab blocks this protein, so the T-cells can destroy melanoma cells. It can help shrink or slow the growth of advanced melanoma.

Is immunotherapy a last resort for melanoma?

What is the success rate of immunotherapy?

Immunotherapy drugs work better in some cancers than others and while they can be a miracle for some, they fail to work for all patients. Overall response rates are about 15 to 20%.

Can Stage 4 melanoma be cured with immunotherapy?

The overall average 5-year survival rate for all patients with melanoma is 92%. This means 92 of every 100 people diagnosed with melanoma will be alive in 5 years. In the very early stages the 5-year survival rate is 99%. Once melanoma has spread to the lymph nodes the 5-year survival rate is 63%.

Can you have melanoma for years and not know?
