Suitability of conventional systematic vs. MRI-guided targeted biopsy approaches to assess surgical treatment delay for radical prostatectomy.

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.
