Prostate Cancer PSA-Negative Treatment: John Tesh’s Story
Here’s a breakdown of John Tesh’s prostate cancer journey, based on the provided text:
1. Initial Diagnosis & Treatment at MD Anderson:
* Care Team: John Tesh was under the care of Dr. Christopher Logothetis, a genitourinary medical oncologist, and Dr. Brian Chapin, a urologic surgeon.
* Surgery: Dr.Chapin performed robotic surgery to remove suspicious lymph nodes.
* Spread & Further Treatment: The surgery confirmed cancer had spread to his lymph nodes.He then underwent four rounds of chemotherapy followed by Androgen Deprivation Therapy (ADT).
* ADT Explained: ADT lowers androgen levels (like testosterone) or prevents them from reaching prostate cancer cells, as these hormones can fuel cancer growth. It can be achieved through testicle removal or medication.
2. Cancer Returns & Decision to Delay Radiation:
* Recurrence: The cancer spread again.
* Radiation Consideration: Doctors at Cedars-Sinai Hospital proposed extensive radiation therapy (“carpet bombing” the pelvis with 30 rounds).
* Decision to Pause: Tesh and his family decided to hold off on radiation due to potential side effects impacting critically important bodily functions.
3. Unique Case & Digital Twin:
* Unusual Cancer: Tesh’s cancer is unusual as it doesn’t produce Prostate-Specific Antigen (PSA). This makes detection and treatment more challenging, as PSA levels are commonly used for screening. His cancer is suspected to be a rare type – small cell prostate cancer.
* Digital Twin: MD Anderson is creating a “digital twin” – a computer simulation – of tesh’s case to help understand and possibly treat his unique cancer.
In essence, the article details a complex and ongoing battle with prostate cancer, highlighting the challenges of treating rare forms of the disease and the innovative approaches being used to find solutions.
