She had a mastectomy 6 months ago and received chemotherapy with doxorubicin and paclitaxel. A CT scan of the chest shows new metastases in the lungs and liver. Adjuvant therapy is initiated with a drug that inhibits the formation of deoxythymidine monophosphate and results in the accumulation of deoxyuridine triphosphate. The patient is advised to avoid folic acid supplementation while receiving this drug in order to prevent the toxic effects of this drug. Which of the following drugs was most likely given? (A) Hydroxyurea (B) Azathioprine (C) Mycophenolate mofetil (D) Capecitabine
