Background
This study aimed to investigate the role of radical prostatectomy (RP) among clinical nodal metastasis prostate cancer and whether histological confirmation of lymph node metastasis through surgery can help with treatment.
Patients and Methods
After excluding patients with distant metastatic prostate cancer or neoadjuvant androgen deprivation therapy, 42 patients with clinical nodal metastasis who underwent RP at our institution were included in the study. We classified them as having or not having pathological lymph node metastasis. Clinicopathologic data were analyzed in this retrospective chart review. Kaplan–Meier analysis was used to calculate the estimated castration-resistant prostate cancer (CRPC)-free survival, biochemical recurrence (BCR)-free survival, and cancer-specific survival (CSS).
Results
There is no significant difference in age, presence of diabetes mellitus, hypertension, BCR time, CRPC time, overall survival, salvage RT rate, and initial prostate-specific antigen level between the two groups. However, there is a significant difference in the pathology N1 group in terms of pathological T stage, pathologic Gleason score, BCR rate, CRPC rate, and CSS. A multivariate Cox proportional hazard regression analysis was used to identify predictors of CRPC-free survival. Patients with pathological lymph node metastasis had a shorter CRPC-free survival [hazard ratio (HR) 4.87; 95% confidence interval (CI) 1.25–19.00, p = 0.02].
Conclusion
Radical prostatectomy can confirm lymph node metastasis. Although pathologic diagnosis has no effect on time to BCR and CPRC, because it affects BCR rate, CRPC rate, and CSS, an accurate pathological diagnosis obtained through surgery is beneficial in the treatment of clinical lymph node metastasis prostate cancer.
