MPO and breast carcinoma: Similarly, in another prospective, randomized, single-blinded clinical trial on 40 patients comparing inhalation anesthesia with propofol-regional anesthesia, also in breast cancer, Aghamelu et al. did not find a significant difference in the serum expression of MPO (10.5 ± 6.6 vs. 11.5 ± 4.7, ng mL−1, p = 0.60) and CitH3 (3.6 ± 2.3 vs. 4.0 ± 5.9, ng mL−1, p = 0.80) between these two anesthetic techniques [113].
