Tumor-directed radiation therapy for high-risk localized prostate cancer

Real-time Image-guided Ultra-hypofractionated Focal Boost to Intraprostatic Lesion(s) With Lymph Node Irradiation for a Very High High-risk Localized Prostate Cancer (the HYPO-RT-PC Boost Trial)

Not applicable Interventional Region Skane · NCT06220435

This study is testing a new type of targeted radiation therapy for men with very high-risk localized prostate cancer to see if it can effectively treat their cancer while using advanced imaging techniques.

What this trial studies

This trial evaluates the safety and efficacy of a real-time image-guided ultra-hypofractionated radiation boost combined with lymph node irradiation for patients with node-negative very high-risk localized prostate cancer. It aims to assess the feasibility of this treatment approach and its effectiveness in targeting high-risk lesions. The study will enroll 76 participants and will utilize advanced imaging methods to define focal boosts during concomitant androgen deprivation therapy.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 and older with histologically confirmed very high-risk localized prostate cancer and specific imaging findings.

Not a fit: Patients with regional or distant metastasis or those who have had previous pelvic radiotherapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective localized therapy for patients with very high-risk prostate cancer, potentially improving outcomes.

How similar studies have performed: Other studies have shown promise with similar ultra-hypofractionated radiation approaches, but this specific combination is novel.
