Epidural anesthesia for this procedure can be associated with referred pain requiring add’nopiods. This could also limit current intensity or duration of therapy. Epi patients did not have any opiod sparing in the post op period.

Data suggests;the possibility that anesthetic conduct may contribute to the recurrence of cancer ( liberal opiod Rx or inadequate analgesia)
Equally worrying is the possibility that anesthesia, or the stress response to surgery could activate dormant cancer cells in an individual undergoing non cancer surgery.
