Doctors are conducting a Phase II trial to see if a treatment made from mistletoe extract (Iscador P) can help children, teens, and young adults with a type of bone cancer called osteosarcoma that has come back after initial treatment. The study is for patients whose cancer has returned but can still be surgically removed. The goal is to see if adding this extract after surgery helps keep the cancer from coming back again.
To get an early idea, researchers looked back at a small pilot study with just 9 young patients. In that small group, 55% were alive without their cancer getting worse one year after their relapse. The study also plans to check if the treatment affects patients' quality of life and their immune system's response.
It is very important to understand that this 55% result comes from a tiny, preliminary study. The new, larger Phase II trial has just started, so we do not have its results yet. This means we cannot say if the mistletoe extract is truly effective or safe for this use. The findings are a first step that needs much more research to confirm.
For now, this research represents an early scientific question being explored. Patients and families should know that this is not a proven treatment. The main takeaway is that researchers are investigating new options, but it will be a long time before anyone knows if this approach works.
