Although many high-risk patients who elect to undergo RP have excellent oncologic outcomes and do not require further adjuvant cancer-directed treatments, significant heterogeneity in clinical outcomes exists . For example, patients with a Cancer of the Prostate Risk Assessment (CAPRA) score of 0-2 have less than a 25% chance of biochemical recurrence at 10 years following radical prostatectomy compared to greater than 75% chance in patients with a CAPRA score of 7-10. Similarly, Dr. Phillip Pierorazio lead a study at Johns Hopkins that showed a significant variation in cancer-specific survival at 15 years post radical prostatectomy between patients with seminal vesicle or lymph node involvement (37%-73%) compared to those without (76-96%) .The heterogeneity of clinical outcomes observed in these studies suggested potentially additional sub-groups within the high risk cohort of prostate cancer patients.

Patients with very-high-risk prostate cancer may require more aggressive therapies in order to achieve optimal oncologic outcomes. Multimodal treatment approaches such as combination radiotherapy/hormonal therapy or surgery with early adjuvant therapy should be considered. Furthermore, patients with very high risk prostate cancer may also be ideal candidates for clinical trials that incorporate neoadjuvant and/or novel multimodal treatment approaches.
- Significant variations in clinical outcomes and cancer-specific survival exist within the NCCN high-risk group
- Patients with one of the following characteristics are thought to have very high risk prostate cancer and may benefit most from multimodal therapy and/or clinical trials:
- Primary Gleason primary pattern 5 on biopsy
- ≥5 cores containing Gleason sum 8-10 cancer on biopsy
- 2 or more of the following characteristics:
- clinical stage ≥T3 stage
- PSA >20ng/ml
There are several exciting clinical trials currently ongoing at Johns Hopkins' Sidney Kimmel Comprehensive Cancer Center for patients with high-risk or advanced prostate cancer:
- Neoadjuvant Study of Androgen Ablation Combined with Cyclophosphamide and GVAX Vaccine for Localized Prostate Cancer https://clinicaltrials.gov/ct2/show/NCT01696877?term=high+risk+prostate+cancer&state1=NA%3AUS%3AMD&rank=13
- Randomized Salvage Radiation Therapy Plus Enzalutamide Post Prostatectomyhttps://clinicaltrials.gov/ct2/show/NCT02203695?term=high+risk+prostate+cancer&state1=NA%3AUS%3AMD&rank=14
- A Pre-surgical Study of LDE225 in Men With High-risk Localized Prostate Cancerhttps://clinicaltrials.gov/ct2/show/NCT02111187?term=high+risk+prostate+cancer&state1=NA%3AUS%3AMD&rank=6

Vinson recently finished a four-week sub-internship at the Brady Urological Institute and gave a presentation to the department on "Very High Risk Prostate Cancer" from which this blog is inspired. Vinson is looking forward to a career in urology.
