Combined with chemotherapy, electric fields help prevent the growth of deadly brain tumors.
The particularly lethal brain cancer known as glioblastoma multiforme is fast-growing, difficult to treat, and nearly always fatal; even with aggressive therapy, patients have a median survival time of less than two years.
But scientists are pursuing new ways to attack this type of brain tumor, and one company may just be succeeding. NovoCure, a small startup founded in Israel in 2000, has developed a device that uses an electric field to disrupt the growth of cancer cells, and early results are promising. Out of ten patients who started using the device in combination with chemotherapy shortly after their initial diagnosis, seven are still alive more than four years later, and five of them show no signs of cancer progression.
