Prospective evaluation of combined oncological and functional outcomes after laparoscopic radical prostatectomy: trifecta rate of achieving continence, potency and cancer control at 2 years.

Abstract

To determine the proportion of patients who are continent, potent and cancer-free (trifecta rate) 2 years after extraperitoneal laparoscopic radical prostatectomy (ELRP). We included patients who underwent an ELRP at our department and who were followed for at least 2 years. Those who were impotent or incontinent before the surgery were excluded from the analysis. Overall, 911 men were included. All patients prospectively completed objective, self-administered questionnaires before the medical visit, concerning their voiding and sexual disorders, before surgery and 12 and 24 months after ELRP. Biochemical recurrence was defined as any detectable serum PSA (≥ 0.2 ng/mL). Potency was defined as the ability to achieve an erection sufficient for penetration with or without the use of phosphodiesterase-5 enzyme inhibitor. Urinary continence was defined as absence, or occasional use, of a pad for anticipated vigorous activity. The primary study endpoint was the trifecta rate (cancer control, continence and potency) at 2 years after the surgery. Factors associated with the trifecta outcome were assessed in univariate analysis. Median age and PSA level were 62.2 years and 9.9 ng/mL, respectively. A trifecta outcome was achieved in 29.7 and 54.4% of patients at 12 and 24 months, respectively. The 2-year trifecta rate reached 63.5% in patients undergoing bilateral nerve-sparing surgery and 73.5% in men aged < 60 years. Age < 60 years, PSA level < 10 ng/mL, organ-confined disease and bilateral nerve-sparing procedure were significantly associated with the 2-year trifecta outcome. A total of 84.8% of patients were both cancer-free and continent at 24 months, regardless of erectile function. Two years after ELRP, the trifecta outcome is achieved in 54.4% of patients who remained potent and continent. This rate reaches 63.5% in patients undergoing a bilateral nerve-sparing procedure. Combined results of good cancer control and continence recovery are reported in 84.8% of patients, regardless of erectile function.
