OUR NEXT VIRTUAL MEETING
Gut Check: What’s the Microbiome and How Does It Affect Your Prostate?
Join us August 22 as Michael A. Liss, MD, PhD, a urologic oncologist and researcher at the University of California, San Diego, explores what the gut microbiome is, why prostate cancer researchers are interested in it, and what the science can — and cannot — tell us today. The discussion will consider possible connections among gut health, inflammation, diet, exercise, and prostate cancer, including what this evolving research may mean for men on Active Surveillance.
EXPLORE ASPI RESOURCES
Explore a few of ASPI’s interactive tools and educational resources designed to help men on Active Surveillance feel more informed and supported.
WE ARE THRIVERS

Thrainn’s Story
In my opinion, my greatest personal accomplishment was to undertake extensive research on my own, followed by choosing AS. When I was diagnosed with PC at the age of 61, my doctors strongly recommended that I undergo traditional treatment. Surgery was at the top of the list.

Mark's Story
Eighteen years ago, I was diagnosed with Gleason 6 prostate cancer at the age of 55 – and, against the advice of five medical professionals (including my wife, a nurse practitioner) I chose not to have intervention.
Years on Active Surveillance
| Patients | Years | Months |
|---|---|---|
| Mark Lichty | 21 | 3 |
| Bill Manning | 17 | 2 |
| Howard Wolinsky | 15 | 2 |
| Geoff McLennan | 14 | 4 |
| David King Keller | 12 | 2 |
| Martin Gewirtz | 8 | 10 |
The following ASPI directors have now entered treatment:
- Thrainn Torvaldsson after 14 years of Active Surveillance.
We share this to help reassure you about the choice you have made—or may be considering. Active Surveillance is chosen not only to avoid or delay side effects, but also to allow time for treatments to evolve.
In Thrainn’s case, our Icelandic board member who was diagnosed nearly two decades ago, waiting meant options improved. Had he been treated at diagnosis, he would likely have received more aggressive treatment than what was ultimately needed years later—thanks to advances in care over time.
LEARN ABOUT THE PREDICT PROSTATE TOOL
Predict Prostate is an evidence-based tool for men with early, non-metastatic prostate cancer who are weighing Active Surveillance and treatment. It provides personalized estimates based on your cancer details, age, and overall health, helping you compare options more realistically and calmly.
