Abstract PR485: Paravertebral Block Use is Not Associated with Longer Survival After Breast Cancer Surgery

Background & Objectives: It has been suggested that the use of paravertebral block (PVB) could decrease the rate of breast cancer recurrence after breast cancer surgery (BCS); however recent studies demonstrate the opposite. We tested the hypothesis that the use of PVB in combination with volatile anesthesia (VA) was associated with longer recurrence free-(RFS) and overall survival (OS) after BCS.
