A trial looking at vaccine treatment after surgery for melanoma skin cancer (EORTC 18961)

This trial looked at 2 vaccines to see if they could help stop melanoma coming back after surgery.

Melanoma is usually treated with surgery. But for some people, there is a risk that the melanoma will come back. Doctors are always looking at new treatments to try to prevent this.

One new treatment is a cancer vaccine. Cancer vaccine research is still in its early stages. But they have shown some promise as a possible new treatment. Vaccines may help the immune system kill cancer cells.

The aim of this trial was to find out if giving 2 vaccines after surgery could help stop the melanoma coming back. The vaccines were called GM2-KLH and QS21.
