Difficulty: MediumUrologic Surgery

A 60-year-old man presents to the urology clinic to establish care and discuss prostate cancer screening. He is in excellent health with no lower urinary tract symptoms. Arrange the following interventions in the most appropriate chronological order, representing the standard clinical pathway from initial screening to potential definitive surgical management for localized prostate cancer.

  1. 1Measurement of serum prostate-specific antigen (PSA) level and digital rectal examination (DRE)
  2. 2Multiparametric magnetic resonance imaging (mpMRI) of the prostate
  3. 3Transrectal ultrasound (TRUS) guided systematic and MRI-targeted prostate biopsy
  4. 4Robot-assisted laparoscopic radical prostatectomy

Answer

The correct sequence is: initial screening (PSA and DRE), followed by imaging (mpMRI), then tissue diagnosis (targeted biopsy), and finally definitive surgical treatment (radical prostatectomy).
The contemporary management pathway for localized prostate cancer follows a strict sequence to maximize diagnostic accuracy and avoid unnecessary interventions. It begins with screening using serum PSA and DRE. If risk is elevated, guidelines now recommend performing a multiparametric MRI (mpMRI) prior to biopsy. This imaging identifies suspicious lesions and allows for targeted tissue sampling. Subsequently, a prostate biopsy (e.g., TRUS-guided) is performed to obtain a definitive histopathological diagnosis and Gleason grade. Only after tissue confirmation of malignancy is definitive surgical management, such as a radical prostatectomy, offered to appropriate surgical candidates.

Step-by-Step Solution

1
Perform initial prostate cancer screening.
Identify elevated risk via an abnormal PSA level or DRE findings.
To determine if a patient requires further, more invasive diagnostic evaluation.
2
Obtain a multiparametric MRI of the prostate.
Localize suspicious prostatic lesions (e.g., PI-RADS 4 or 5).
To guide subsequent biopsy targeting, which improves the detection rate of clinically significant prostate cancer.
3
Perform a prostate biopsy with appropriate targeted prophylaxis.
Confirm the diagnosis of prostate cancer with histopathology and establish a Gleason score.
Tissue diagnosis is an absolute prerequisite before any definitive treatment for prostate cancer can be initiated.
4
Perform a radical prostatectomy.
Surgically extirpate the prostate gland and seminal vesicles.
To provide definitive surgical treatment for localized, clinically significant prostate cancer in an otherwise healthy patient.
