A cure for cancer teems through our veins, but the trick is harnessing the immune system's tumour-destroying cells, say doctors.
Now, a US team has developed a new way to turn a patient's T-cells against a deadly, metastasised skin cancer. A 55-year old man who received the immune boost lives tumour-free, more than two years after treatment.
“He had a remarkable response,” says Cassian Yee, an immunologist at Fred Hutchinson Cancer Research Center in Seattle, Washington, US, who developed the new treatment.
Yee’s team treated eight other melanoma patients, but he says it is too early to tell whether their tumours have vanished as well.
Other cancer experts say the results could pave the road for a cancer vaccine, but more proof with additional patients is needed.
