The question is what should be done to take advantage of the benefits that the study suggests exist. Study author Dr. Ying Taur (from New York's Memorial Sloan Kettering Cancer Center) says:
One possible strategy is to find ways to perform transplants in a manner that minimizes damage to the gut microbiota. Another approach would be to replenish the gut with beneficial microbes that are lost after this procedure is performed.
And of course to push for further research.
