A study just published in The Journal of Experimental Medicine followed 266 patients after surgical resection of their tumors and post-operative chemotherapy and/or radiotherapy.  Those patients regularly taking aspirin or another NSAID for 6 months and also having an activated PIK3CA gene were 3 times more likely to survive 5 years.  Specifically, the average survival rate rose from a baseline of 25 percent to a gratifying 78 percent.  Those without the PIK3CA gene mutation enjoyed no survival benefit. A larger, confirmatory study is now underway.  Meanwhile, know that the PIK3CA oncogene is present and mutated in about one-third of other cancers including colon, stomach, esophageal, pancreatic, liver, breast, cervical, endometr
