The perioperative period in cancer surgery is characterized by transient metabolic and inflammatory perturbations that may influence early postoperative biochemical dynamics. Surgical stress induces insulin resistance, hyperglycemia, cytokine activation, and metabolic shifts that interact with tumor cell signaling pathways. Intravenous lidocaine has been associated with anti-inflammatory and systemic stabilizing effects beyond analgesia. We investigated whether perioperative lidocaine administration during robotic-assisted radical prostatectomy (RARP) is associated with early postoperative prostate-specific antigen (PSA) dynamics within the context of perioperative metabolic-inflammatory modulation. In this single-center retrospective cohort study, 180 patients undergoing RARP for localized or locally advanced prostate cancer were stratified according to perioperative intravenous lidocaine exposure. The primary endpoint was undetectable PSA (<0.1 ng/mL) at 6-12 weeks postoperatively. Secondary endpoints included PSA detectability at 3 and 6 months and time to first detectable PSA. Multivariable logistic and Cox regression models were adjusted for established oncologic risk factors. Perioperative glycemic variation, intraoperative lactate dynamics, and postoperative IL-6 levels were analyzed as indicators of stress-induced metabolic activation. Lidocaine exposure was independently associated with higher odds of undetectable PSA at 6-12 weeks (OR 2.10, 95% CI 1.15-3.85) and at subsequent time points. In Cox analysis, lidocaine was associated with a reduced hazard of PSA detectability (HR 0.58, 95% CI 0.37-0.92). Patients receiving lidocaine demonstrated significantly attenuated perioperative hyperglycemia, lower lactate elevation, and reduced IL-6 response. Perioperative intravenous lidocaine administration during RARP was associated with more favorable early PSA dynamics and attenuation of perioperative metabolic-inflammatory activation. Given the retrospective and non-randomized design of the study, these findings should be interpreted as associative and hypothesis-generating, and warrant confirmation in prospective controlled investigations.

: Surgical stress during robotic-assisted radical prostatectomy (RARP) elicits a measurable systemic inflammatory response despite the minimally invasive approach. Intravenous lidocaine has been increasingly investigated for its potential anti-inflammatory, analgesic, and immunomodulatory benefits, but evidence in robotic urologic oncology remains limited. This study aimed to evaluate whether intraoperative lidocaine infusion attenuates postoperative inflammation, improves analgesic outcomes, and accelerates early recovery following RARP. : This prospective non-randomized observational study included 80 patients undergoing elective RARP, divided into a Lidocaine Group ( = 40) receiving an intraoperative bolus and continuous infusion, and a Control Group ( = 40) receiving standard anesthesia without lidocaine. Serum IL-6, TNF-α, CRP, and fibrinogen were measured at baseline, end of surgery, and 24 h postoperatively. Postoperative pain scores, opioid consumption, gastrointestinal recovery, ambulation, and length of stay were recorded. Statistical analyses included repeated-measures ANOVA, correlation testing, and between-group comparisons. : Baseline characteristics were similar between groups. At 24 h postoperatively, lidocaine administration was associated with a significantly attenuated inflammatory response, with lower levels of IL-6 (45.7 ± 10.8 vs. 68.9 ± 12.6 pg/mL, < 0.01) and TNF-α (20.5 ± 5.1 vs. 27.2 ± 6.4 pg/mL, < 0.01) compared with controls. Patients receiving lidocaine reported lower postoperative pain scores and required significantly less opioid analgesia, with a total 24 h consumption of 8.9 ± 3.4 vs. 14.8 ± 5.2 mg morphine milligram equivalents ( < 0.001). Lidocaine was also associated with faster recovery, including earlier oral intake and a shorter length of hospital stay (2.9 ± 0.7 vs. 3.6 ± 0.9 days, = 0.003). No lidocaine-related adverse events were observed. : In this prospective observational study, intraoperative intravenous lidocaine was associated with attenuated early postoperative inflammation, improved analgesic outcomes, and enhanced early recovery following RARP. These findings support the potential role of intravenous lidocaine as a safe adjunct in multimodal perioperative management; however, given the non-randomized observational design, causal inferences should be interpreted with caution. Further randomized controlled trials are warranted to confirm causality and to validate long-term clinical and mechanistic effects. Potential residual confounding inherent to the observational design should be considered when interpreting these findings.
