Image-guided Radiotherapy for Prostate Cancer
(RAD-TARGET Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new type of radiation therapy for prostate cancer that targets the tumor more precisely. Researchers aim to determine if this focused treatment reduces side effects on nearby organs compared to standard whole-prostate radiation. They will assess side effects, survival rates, and quality of life. Men with prostate cancer planning to undergo radiation therapy, who have visible lesions on specific scans, might be suitable candidates. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to advancements in cancer care.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this image-guided tumor-focused radiotherapy is safe for prostate cancer patients?
Studies have shown that image-guided radiotherapy for prostate cancer is generally well-tolerated by patients. Research indicates that survival rates for patients receiving this therapy are similar to those undergoing standard treatments, suggesting comparable safety.
Radiation therapy for prostate cancer can sometimes cause side effects like tiredness or skin irritation. Image-guided therapy aims to reduce these effects by precisely targeting the tumor and minimizing radiation exposure to nearby organs. This approach may lead to fewer issues with organs close to the prostate, such as the bladder and intestines.
Currently, an early-phase trial is testing this treatment to assess its safety for patients. While no major safety concerns have been reported so far, this phase of the study will provide more detailed information on any possible side effects.12345Why do researchers think this study treatment might be promising for prostate cancer?
Researchers are excited about image-guided tumor-focused radiation therapy for prostate cancer because it offers a more precise approach than traditional radiation methods. Unlike standard radiation therapy, which targets a broader area, this technique directly focuses on the tumor, potentially reducing damage to surrounding healthy tissues. This targeted method may lead to fewer side effects and improved outcomes, making it a promising advancement in prostate cancer treatment.
What evidence suggests that image-guided tumor-focused radiotherapy is effective for prostate cancer?
This trial will compare standard dose radiotherapy with image-guided, tumor-focused radiation therapy for prostate cancer. Studies have shown that image-guided, tumor-focused radiation therapy can effectively treat prostate cancer. In one study, patients who received this treatment experienced fewer bowel problems and improved quality of life compared to those who underwent standard radiation therapy targeting the whole prostate. This method may also reduce the radiation dose to nearby organs, potentially resulting in fewer side effects. Research suggests that real-time imaging helps target the treatment more precisely at the cancer, potentially leading to better patient outcomes.46789

Are You a Good Fit for This Trial?
This trial is for men over 18 with intermediate or high-risk prostate cancer, who have a visible lesion on MRI or PSMA PET-CT and plan to undergo curative-intent radiation therapy. They must consent to the study's procedures and be available throughout its duration. Men able to cause pregnancy must use effective contraception during treatment and for six months after.Inclusion Criteria
