Introducing a new, simple scoring system to evaluate oncological and functional outcome after radical prostatectomy

Abstract

Objective: To create a scoring system which takes into account oncological outcome and functional results (continence and erectile function) of patients after radical prostatectomy.

Material and Methods: A total of 146 consecutive men underwent radical prostatectomy for localized prostate cancer and were evaluated 1 year after surgery. Biochemical recurrence was defined as a single postoperative prostate‐specific antigen (PSA) level of > 0.2 ng/ml. Continence, defined as not using a pad, and potency, defined as the ability to achieve and maintain an erection suitable for sexual intercourse, were evaluated by means of a prospective, self‐administered questionnaire. Each patient received 4 points (if PSA was <0.2 ng/ml) or 0 points (if PSA was >0.2 ng/ml) for oncological outcome, 2 points (if continent) or 0 points (if incontinent) for urinary continence and 1 point (if potent) or 0 points (if impotent) for erectile function. The total score was calculated, with higher scores indicating a better outcome. The unique feature of this scoring system is that each individual score represents a particular clinical status regarding oncological and functional outcome.

Results: One year after surgery, 121 (82.8%) patients had PSA levels of <0.2 ng/ml, 103 (70.5%) were continent and 53 (36.3%) were potent. Patients with a total score of ≥4 points had good cancer control and could be further subdivided into those who were continent and potent (7 points; 22.6%), those who were continent but had erectile dysfunction (ED) (6 points; 34.2%), those who were incontinent and potent (5 points; 8.2%) and those who were incontinent and had ED (4 points; 17.8%). Similarly, patients with a score of <4 points had no cancer control and could be further subdivided into those who were continent and potent (3 points; 3.4%), those who were continent but had ED (2 points; 10.3%), those who were incontinent and potent (1 point; 2.1%) and those who were incontinent and had ED (0 points; 1.3%).

Conclusions: This scoring system includes the three most important outcomes after radical prostatectomy, namely cancer control, continence and erectile function. It may allow us to better evaluate, communicate and compare the results of radical prostatectomy in a multinational, multicenter setting.

• erectile dysfunction
• outcome assessment
• prostatectomy
• urinary incontinence
