Researchers Report Cancer Cured with Immunotherapy

In a bid to make cancer immunotherapy more effective, researchers report

they have succeeded in halting the progress of aggressive melanoma in

its tracks in seven patients treated with an army of cloned

cancer-fighting immune cells. In one of those patients, the treatment

resulted in complete remission of his metastatic melanoma and evidence

that his immune system stands ready to fight any return of the cancer

after three years.

The study, published Monday in the Proceedings of the National Academy

of Sciences, contributes to hopes that a tumor-fighting strategy called

immunotherapy can slow, halt or even reverse the growth of a range of

cancers--and do so with fewer dangerous side effects.

Immunotherapy is one of medicine's most promising--and most

problematic--approaches to cancer treatment. It aims to charge up the

patient's immune system to attack cancer cells and halt their

out-of-control growth.
