{"Based on the genotype result, this patient is predicted to be a DPYD intermediate metabolizer (activity score 1) and has an increased risk of severe toxicity when treated with 5-fluorouracil. Reduce starting dose by 50% followed by titration of dose based on toxicity or therapeutic drug monitoring (if available). To maintain efficacy, increase the dose in patients experiencing no or clinically tolerable toxicity in the first two cycles; decrease the dose in patients who do not tolerate the starting dose to minimize toxicities. Please consult a clinical pharmacist for more information."}
