The Los Angeles Times (3/6, Healy) reports, “In a bid to make cancer immunotherapy more effective, researchers report they have succeeded in halting the progress of aggressive melanoma in its tracks — at least briefly — in seven patients treated with an army of cloned cancer-fighting immune cells.” Researchers found that, “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 research, “published Monday in the Proceedings of the National Academies of Science, 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.” WebMD (3/6, DeNoon) also covers the story.
