Background: Some studies have demonstrated that chemotherapy drugs enhance sensitivity to anesthetics owing to its systemic toxicity, while others have demonstrated that chemotherapy drugs have no effect. This study aimed to determine whether neoadjuvant chemotherapy influences the effect-site concentration (Ce) of propofol for sedation in patients with breast cancer. Methods: This study included patients aged 19–75 years who were scheduled to undergo breast cancer surgery under general anesthesia. Patients who received neoadjuvant chemotherapy were assigned to group C, whereas those who never received chemotherapy were assigned to group N. Propofol was administered through an effect-site target-controlled infusion, and the (MOAA/S) score and Bispectral Index (BIS) were recorded. When the plasma concentration and Ce were equal to the target Ce, and if the MOAA/S score did not change, the target Ce was increased by 0.2 μg/ml; otherwise, the Ce was maintained for 2 min and then increased. This process was repeated until the MOAA/S score became 0. Results: No significant differences were observed in Ce values at each sedation level between both groups. Ce values for loss of consciousness (LOC) of groups C and N were 2.76 ± 0.29 and 2.67 ± 0.27 μg/ml (P = 0.285), respectively. However, the BIS value at LOC of group C (63.87 ± 7.04) was lower than that (68.44 ± 6.01) of group N (P = 0.018).Conclusions: Neoadjuvant chemotherapy for breast cancer has no effect on the Ce of propofol for sedation.
