Treatment Recommendations for Intermediate-High Risk Prostate Cancer

Introduction to Treatment Options

The American Urological Association recommends radical prostatectomy as the preferred definitive treatment for a 58-year-old male with Gleason 4+3 prostate cancer, PSA 9, and negative PET scan, due to its ability to provide complete pathologic staging and the option for salvage radiation if needed 1

The National Comprehensive Cancer Network guidelines indicate that patients with intermediate-high risk prostate cancer, such as those with Gleason 4+3, have a worse prognosis than those with Gleason 3+4 1
A negative PET scan confirms organ-confined disease, making the patient an excellent candidate for curative-intent local therapy 1

The Journal of the National Comprehensive Cancer Network notes that surgery provides definitive pathologic staging, allowing for risk-stratified adjuvant therapy decisions 2, 1
The Annals of Oncology reports that salvage radiation after surgery has a proven survival benefit when PSA rises, especially when given early (PSA <0.5 ng/mL achieves 48% 6-year biochemical control) 3, 5
The Journal of the National Comprehensive Cancer Network states that surgery has advantages over radiation, including no bowel toxicity 6, 7

The American Urological Association recommends confirming surgical candidacy by assessing comorbidities, baseline urinary function, and sexual function before proceeding with radical prostatectomy 1
The National Comprehensive Cancer Network guidelines suggest proceeding with radical prostatectomy with bilateral nerve-sparing if preoperative erectile function is good and cancer appears organ-confined, and extended pelvic lymph node dissection given Gleason 4+3 1
The Annals of Oncology and the Journal of Clinical Oncology recommend post-operative surveillance with PSA every 3-6 months to detect biochemical recurrence early (PSA >0.2 ng/mL) 5, 8

The Journal of the National Comprehensive Cancer Network notes that adverse pathology (positive margins, extraprostatic extension, seminal vesicle invasion) should be treated with adjuvant radiation before PSA rises >1.5 ng/mL 2
The Annals of Oncology reports that biochemical recurrence should be treated with salvage radiation when PSA <0.5 ng/mL for best outcomes 3, 5
