神經生長會刺激前列腺癌 Nerve growth stimulates prostate cancer Prostate cancer cells (seen in coloured scanning electron micrograph). Inhibiting the growth of nerve fibres has been shown to slow down the spread of this type of cancer, at least in mice. GOPAL MURTI/SPL The growth of new nerves in and around prostate cancers spurs tumours to grow and invade other tissues, studies in mice have shown. The results, published today in Science, could steer researchers towards novel approaches to treating cancer. Although it is not yet clear whether the mechanism occurs in humans — or in cancers affecting other organs — an analysis of samples from 43 patients with prostate cancer found that nerve density was high in patients who fared poorly in the clinic. “It’s a catalytic paper,” says John Isaacs, a cancer researcher at the Johns Hopkins Medical Institutions in Baltimore, Maryland, who was not affiliated with the study. “People may now focus on trying to tackle these unanswered questions.”
