Cancer Topics – Research to Practice: Prostate Cancer (Part 1)

In this episode of ASCO Educational podcasts, we'll explore how we interpret and integrate recently reported clinical research into practice. The first scenario involves a 72-year old man with high-risk, localized prostate cancer progressing to hormone-sensitive metastatic disease. Our guests are Dr. Kriti Mittal (UMass Chan Medical School) and Dr. Jorge Garcia (Case Western Reserve University School of Medicine). Together they present the patient scenario (1:12), review research evidence regarding systemic and radiation therapy for high-risk localized disease (5:45), and reflect on the importance of genetic testing and (10:57) and considerations for treatment approaches at progression to metastatic disease (16:13).

Today we'll explore how we interpret and integrate recently reported clinical research into practice, focusing on two clinical scenarios: localized prostate cancer progressing to hormone-sensitive metastatic disease; and a case of de novo metastatic hormone-sensitive prostate cancer progressing to castration-resistant disease.

My name is Kriti Mittal and I am the Medical Director of GU Oncology at the University of Massachusetts. I am delighted to co-host today's discussion with my colleague, Dr. Jorge Garcia. Dr. Garcia is a Professor of Medicine and Urology at Case Western Reserve University School of Medicine. He is also the George and Edith Richmond Distinguished Scientist chair and the current chair of the Solid Tumor Oncology Division at University Hospital's Seidman Cancer Center. Let me begin by presenting the first patient scenario. Case 1: A 72-year-old male was referred to urology for evaluation of hematuria. A rectal exam revealed an enlarged prostate without any nodules. A CT urogram was performed that revealed an enlarged prostate with bladder trabeculations. A cystoscopy revealed no stones or tumors in the bladder, but the prostatic urethra appeared to be abnormal looking. Transurethral resection of the prostate was performed. The pathology revealed Gleason score 4+5=9 prostate cancer, involving 90% of the submitted tissue. PSA was performed one week later and was elevated at 50. Patient declined the option of radical prostatectomy and was referred to radiation and medical oncology. So I guess the question at this point is, Dr. Garcia, in 2023, how do you stage patients with high-risk localized prostate cancer and how would you approach this case? Dr. Jorge Garcia: That's a great question and a great case, by the way, sort of what you and I in our practice will call 'bread and butter'. Patients like this type of case that you just presented come from different places to our practice. So either they come through urology or oftentimes they may come through radiation oncology. And certainly, it depends where you practice in the United States, at 'X', US, they may come through medical oncology. So I think that the first question that I have is
