Effect Of Anesthesia In Surgery Of Prostate Cancer – Part 1 of 3
Effect Of Anesthesia In Surgery Of Prostate Cancer. For men having prostate cancer surgery, the exemplar of anesthesia doctors use might make a reformation in the odds of the cancer returning, a new study suggests. Researchers found that of nearly 3300 men who underwent prostate cancer surgery, those who were given both general and regional anesthesia had a lower risk of seeing their cancer course than men who received only general anesthesia. Over a period of 15 years, about 5 percent of men given only general anesthesia had their cancer recur in their bones or other sites, the researchers said.
That compared with 3 percent of men who also received regional anesthesia, which typically meant a spinal injection of the palliative morphine, plus a numbing agent. None of that, however, proves that anesthesia choices in a beeline affect a prostate cancer patient’s prognosis. “We can’t conclude from this that it’s cause-and-effect,” said senior researcher Dr Juraj Sprung, an anesthesiologist at the Mayo Clinic in Rochester, Minn.
But one theory is that spinal painkillers – go for the opioid morphine – can make a difference because they curb patients’ need for opioid drugs after surgery. Those post-surgery opioids, which adopt the whole body, may decrease the immune system’s effectiveness. That’s potentially important because during prostate cancer surgery, some cancer cells usually vamoose into the bloodstream – and a fully functioning immune response might be needed to kill them off. “If you avoid opioids after surgery, you may be increasing your ability to fight off these cancer cells.
