Georgia Tech Research (June 8th, 2020) Contrary to common medical guidance, chemotherapy does not appear to be the only culprit in neuropathy, a neurological side effect of cancer treatment, a new study says. Cancer itself contributes heavily, too, and the stresses on neurons appear far worse than the sum of the two causes. “There was some distress caused by cancer alone and some distress from chemo alone, but when you put the two things together, it was off the charts, seven times the trauma to neurons of the two things added together,” said Nick Housley, first author of the study performed in rats at the Georgia Institute of Technology. “It turned out to be the first-ever evidence that there is this exacerbation going on.” Every year in the U.S., there are 1.8 million new cancer diagnoses, and about half of patients receive platinum-based drugs, which are very effective. About 40 percent of patients receiving platinum chemotherapy come down with neuropathy, suffering strange sensations, pain, fatigue, or loss of muscle coordination that impedes day-to-day life. Neuropathy can persist for years after chemotherapy ends. |
