OBJECTIVES: To assess if systematic (SBx) vs. transrectal or transperineal mpMRI-ultrasound targeted combined with systematic (TBx + SBx) biopsy confer different effects on treatment delay to radical prostatectomy measured as Gleason grade group (GGG) upgrade of prostate cancer (PCa).
MATERIALS AND METHODS: We relied on a multi-institutional cohort of localized PCa patients who underwent RP in Martini-Klinik, Hamburg, or Prostate Center Northwest, Gronau, between 2014 and 2022. Analyses were restricted to PCa GGG 1-3 diagnosed at SBx (n = 4475) or TBx + SBx (n = 1282). Multivariable logistic regression modeling (MVA) predicting RP GGG upgrade of ≥ 1 was performed separately for SBx and TBx + SBx.
RESULTS: Treatment delay to RP of < 90, 90-180 and 180-365 days was reported in 59%, 35% and 6.2% of SBx and in 60%, 34% and 5.9% of the TBx + SBx patients, respectively. Upgrade to GGG ≥ 4 at RP was detected in 15% of SBx patients and 0.86% of TBx patients. In MVA performed for SBx, treatment delay yielded independent predictor status (OR 1.17 95% CI 1.02-1.39, p = 0.028), whereas for TBx + SBx MVA, statistical significance was not achieved.
CONCLUSION: Treatment delay remained independently associated with radical prostatectomy GGG upgrade after adjustment for clinical variables in the patients diagnosed with SBx alone, but not in those who received combined TBx + SBx. These findings can be explained through inherent misclassification rates of SBx, potentially obfuscating historical observations of natural PCa progression and potential dangers of treatment delay. Thus, mpMRI-guided combined TBx + SBx appears mandatory for prospective delay-based examinations of PCa.
