What side effects are associated with this type of intervention?

Common treatments for prostate cancer, including SBRT, can have various side effects. SBRT, which delivers highly focused radiation doses, aims to minimize damage to surrounding healthy tissue but can still cause urinary and bowel issues, fatigue, and erectile dysfunction. Traditional radiation therapy and surgery may also lead to similar side effects, with surgery additionally posing risks of incontinence and infection. Androgen deprivation therapy (ADT), often used in advanced cases, can result in hot flashes, decreased libido, osteoporosis, and metabolic changes. Patients should discuss these potential side effects with their healthcare provider to make informed treatment decisions.

What prior FDA approvals exist?

The FDA has approved several treatments for prostate cancer, including various forms of radiation therapy. Stereotactic Body Radiation Therapy (SBRT) is a newer, highly precise form of radiation therapy that targets tumors with minimal damage to surrounding tissues. While SBRT itself is being studied for its efficacy in prostate cancer, other FDA-approved treatments include external beam radiation therapy (EBRT) and brachytherapy. Additionally, androgen deprivation therapy (ADT) and newer hormonal agents like enzalutamide and abiraterone have been approved for advanced stages of the disease. These treatments aim to manage and control prostate cancer, improving patient outcomes and quality of life.

What other types of research exist?

Promising novel alternatives to SBRT for prostate cancer patients include focal therapies such as thermal ablation (using heat), cryotherapy (using cold), High-Intensity Focused Ultrasound (HIFU), laser ablation (FLA), and irreversible electroporation (IRE). These methods aim to target the tumor precisely while minimizing damage to surrounding healthy tissue. Additionally, systemic treatments like androgen deprivation therapy (ADT) combined with newer agents such as abiraterone, enzalutamide, or apalutamide, and advanced imaging techniques for better targeting, are also promising options.

Summary

This trial investigates a new radiation treatment called SBRT for men with early-stage prostate cancer. SBRT uses small gold seeds and advanced imaging to precisely target and kill cancer cells while minimizing damage to healthy tissue. The goal is to provide an effective treatment with fewer side effects compared to traditional methods. SBRT is a newer radiotherapy method for prostate cancer, developed to deliver high doses of radiation with improved precision.

Who is the study for?

This trial is for men aged 18+ with untreated localized prostate cancer that hasn't spread outside the gland. They must be able to consent, have a performance status indicating they can carry out daily activities, and agree to use effective contraception during and up to 120 days post-treatment. Exclusions include those planning other treatments like ADT or chemotherapy, with high-risk prostate cancer features, prior curative treatment for prostate cancer, certain infections unless treated and cured, or conditions preventing MRI scans.

What is being tested?

The trial tests focal therapy using SBRT on patients with a single tumor in the prostate. It aims to see if this targeted radiation approach leads to fewer side effects than whole-gland surgery or radiation. Participants will undergo two sessions of SBRT about one week apart without sedation and follow-up for two years including scans (MRI & PSMA PET/CT) and blood tests.

What are the potential side effects?

Potential side effects from SBRT may include urinary issues due to inflammation near the treated area, fatigue from radiation exposure, skin reactions at the site of treatment such as redness or soreness, bowel changes like diarrhea if nearby intestines are affected by radiation.

Other Research

The most common treatments for prostate cancer include surgery, traditional radiation therapy, and SBRT. Surgery involves removing the prostate gland to eliminate cancerous tissue but can lead to significant side effects. Traditional radiation therapy uses high-energy rays to kill cancer cells but often affects surrounding healthy tissue, causing side effects. SBRT, a newer form of radiation therapy, delivers highly focused radiation doses directly to the tumor, minimizing damage to surrounding healthy tissue. This precision reduces side effects and improves the quality of life for patients. Understanding these mechanisms helps prostate cancer patients make informed decisions about their treatment options, balancing effectiveness and potential side effects.
