Effect Of Anesthesia In Surgery Of Prostate Cancer – Part 2 of 3
The study, reported online Dec 17, 2013 in the British Journal of Anaesthesia, is not the before all to see a link between regional anesthesia and a lower risk of cancer recurrence or progression. Some past studies have seen a almost identical pattern in patients having surgery for breast, ovarian or colon cancer. But those studies, like the current one, point only to a correlation, not a cause-and-effect link. Dr David Samadi, superintendent of urology at Lenox Hill Hospital in New York City, agreed.
And “We have to be very careful about how we interpret these results,” said Samadi, who was not involved in the new study. One powerful issue is that the men in this study all had open surgery to remove their prostate gland. But these days, the surgery is almost always done laparoscopically – a minimally invasive approach in which surgeons make a few niggardly incisions. In the United States most of these procedures are done with the aid of robotic “arms”. Compared with traditional open surgery, laparoscopic surgery is quicker and causes less stress, blood loss and post-surgery pain. And in his occurrence patients’ need for opioids after surgery is low.
Sprung agreed that it’s not clear whether the current findings extend to men having laparoscopic surgery. The findings are based on the records of nearly 3300 men who had prostate cancer surgery between 1991 and 2005 at the Mayo Clinic. Half had been given only blanket anesthesia, while the other half had received regional anesthesia as well. In 83 percent of the cases, that meant a spinal cube containing morphine. The researchers weighed other factors, such as the stage of the cancer and whether a man received radiation or hormone therapy after surgery.
