Use of PVB Has No Effect on Cancer Survival

January 6, 2017

Contrary to some previous studies, the use of paravertebral block (PVB) is not associated with a reduced rate of cancer recurrence or improved survival after breast cancer surgery, recently released research suggests.  Dr. Juan P. Cata  assistant professor of anesthesiology and perioperative medicine at the University of Texas MD Anderson Cancer Center, in Houston and his colleagues conducted a retrospective analysis of 792 women who had undergone breast cancer surgery under general volatile anesthesia with and without PVB to explore any connection with cancer recurrence or overall survival. The researchers developed two propensity score models to create a matched sample of patients based on important clinical covariates. The findings were presented at the 2016 World Congress of Anaesthesiologists (abstract PR485).
