Objective: To evaluate the impact of radical prostatectomy (RP) and extended pelvic lymph node dissection (EPLND) on the disease process in terms of oncological outcomes and quality of life in the treatment of clinical stage C T3N0M0 prostate cancer (PCa).

Materials and Methods: The data of patients with cT3N0M0 who had undergone open radical prostatectomy and extended pelvic lymph node dissection in our clinic between January 2015 and March 2021 were analyzed retrospectively. Preoperative and postoperative data were compared in terms of oncological and functional outcomes. Biochemical recurrence was accepted as detection of PSA >0.2 ng/ml on consecutive measurements and biochemical disease-free survival time was calculated.

Results: The mean age of 23 operated patients who met the study criteria, was 66.8±7.4 years. In the pathological staging, the organ-confined disease was detected in 10 (43.4%) patients. Surgical margin positivity was observed in 6 (26.2%), while lymph node positivity in 3 (13.1%) patients. Biochemical recurrence was detected in 7 (30.2%) patients during a mean follow-up period of 33.6±22.9 months. The mean biochemical disease-free survival time was 48.4±6.3 months. In the evaluations of the patients at the postoperative 6^th months, a 3.2±2.2-point decrease was found in the International Prostate Symptom Score (IPSS) (p=0.001) and a 13.1±5.0 point decrease in the International Index of Erectile Function (IIEF) score (p=<0.001).

Conclusions: Radical prostatectomy and extended pelvic lymph node dissection applied in the treatment of locally advanced prostate cancer is seem to be an effective and safe treatment method in terms of oncological and functional outcomes.
