Mycophenolate mofetil is another antiproliferative agent. Hepatic and renal testing is appropriate if someone is already on these agents. Although there are little to no data to guide perioperative use, "it can be continued in the perioperative period in absence of infection or liver or renal disease," according to Dr. Whinney.
Sirolimus and everolimus are potent antiproliferative agents in the mTOR inhibitor class. An increased risk for wound complications or wound seromas is a relevant perioperative issue. Obesity and concomitant use of steroids add to this risk. A systematic wound care program can reduce the rate of wound healing complications back to baseline, Dr. Whinney said.
Dr. Whinney recommended stopping sirolimus or everolimus 2-4 weeks prior to major or abdominal surgery to allow clearance of this long half-life agent from the body. Replace the agent with an appropriate calcineurin inhibitor. "Again, if you are unfamiliar with these agents, use them in conjunction with a transplant specialist."
