The present study investigated the association between radical prostatectomy (RP) and the risk of herpes zoster (HZ). Male patients aged ≥ 40 years and diagnosed with prostate cancer (PCa) between 2000 and 2005 were included in this study. Patients who underwent RP for the first time during 2000–2006 were included in the RP group. Randomly selected individuals from among the remaining patients with PCa who did not undergo RP were included in the non-RP group. Univariate and multivariate Cox regression models were used to analyze the association between PCa and HZ. In addition, the association between RP and the risk of HZ in different subgroups was evaluated after stratification by age, comorbidities, and hormone therapy (HoT) status. Furthermore, the combined effect of RP and HoT on the risk of HZ was evaluated. This study included 1,380 patients with PCa who newly underwent RP and 1,371 patients with PCa who did not undergo RP. During follow-up, 96 and 104 patients in the RP and non-RP groups, respectively, developed HZ. Patients who underwent both RP and HoT showed a significantly reduced risk of HZ, compared with patients who did not undergo both RP and HoT. RP is not associated with an increased risk of HZ. However, prostate-specific antigen levels should be monitored routinely during follow-up to detect PCa recurrence.
