Ts 5fu
WebHow do you have fluorouracil (5FU) and mitomycin C? You have mitomycin and fluorouracil into your bloodstream. You may be able to have the infusions of 5FU at home if you have a central line. To have the 5FU at home, you need to have the infusions through a small pump. You can keep the pump in a small bag, or a bag on a belt (like a bum bag). WebThis in turn causes a reduction of the purine and DNA synthesis. Finally, RTX-5FU synergism might also result from a depletion in dTTP that occurs following TS inhibition by either agent and that may induce negative feedback on deoxycytidylate deaminase, ribonucleotide reductase, and thymidine kinase that synergistically block DNA synthesis .
