Brief Summary
Breast cancer is the most commonly diagnosed cancer in females and the second leading cause of death from cancer in women. It was estimated that 2 million new cases have occurred in 2018 worldwide 1. Standard anesthetic procedures for the surgery of breast cancer include general and regional anesthesia 2. Growing preclinical and clinical data support the hypothesis that anesthetic choice may affect cancer-related outcomes. Recurrence in breast cancer was reduced to four-fold in a retrospective study with a 2.5 to 4 year follow up 3. Recurrence and metastasis-free survival, with multivariate analysis, was 94% (95% CI 87,100) versus 82% (74, 91) at 24 months, and 94 (87, 100) versus 77 (68, 87) at 36 months in the paravertebral and general anesthesia patients, respectively, (p=0.013). Currently large confirmatory randomized trials evaluating breast cancer recurrence in patients operated with general or regional anesthesia are yet undergoing 4.
