The effect of epidural analgesia added to general anesthesia on systemic immune-inflammation index in radical prostatectomy surgery: A retrospective study.

Background: Systemic immune-inflammation index (SII) is increasingly valued for its simplicity and predictability. Anesthesia/analgesia technique may affect cancer survey.

Aims: The primary aim of this study is to offer a comparative evaluation for the effect of different anesthesia/analgesia techniques employed in radical prostatectomy surgery on SII, a new inflammatory index.
