Perioperative lidocaine vs high-dose dexamethasone for colon cancer surgery

Effect of Perioperative Intravenous Infusion of Lidocaine or High Dose Dexamethasone on the Immune Response in Patients Undergoing Surgery for Colon Cancer - The PILDI Study

Phase 2 Interventional Institute of Oncology Ljubljana · NCT07432399

This trial tests whether giving intravenous lidocaine around the time of surgery instead of high‑dose dexamethasone helps preserve immune function and improve recovery in adults having colon cancer surgery.

What this trial studies

This randomized, double‑blind phase II trial at the Institute of Oncology Ljubljana enrolls adults with histologically confirmed colon cancer scheduled for elective resection. Participants are randomly assigned to receive either a perioperative intravenous lidocaine infusion or high‑dose perioperative dexamethasone, with participants and clinical staff blinded to assignment. The study measures postoperative immune response markers and clinical outcomes such as recovery and complication rates. Findings will compare the immunomodulatory and clinical effects of the two perioperative approaches.

Who should consider this trial

Good fit: Ideal candidates are adults with confirmed colon cancer who are scheduled for elective surgical resection, are eligible for perioperative lidocaine or dexamethasone, and can give informed consent.

Not a fit: Patients with severe liver or kidney impairment, significant cardiac conduction disorders, known allergy to lidocaine or dexamethasone, pregnant or breastfeeding patients, or those judged unsuitable by investigators are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could identify a simple perioperative medication strategy that preserves immune function, speeds recovery, and reduces complications after colon cancer surgery.

How similar studies have performed: Prior work has reported anti-inflammatory and immunomodulatory effects of perioperative lidocaine and routine perioperative benefits of dexamethasone, but direct randomized comparisons of their effects on immune markers in colorectal cancer surgery remain limited.
