What this trial studies

This clinical trial investigates the effectiveness of combining carbon ion and proton radiotherapy for patients diagnosed with prostate cancer that has spread to pelvic lymph nodes. The study aims to determine if this advanced radiation therapy can improve treatment outcomes compared to standard approaches. Patients will undergo imaging assessments to confirm their cancer stage and suitability for the treatment. The trial focuses on patients who have not received prior pelvic radiation or surgery and are within a specific age range.

Who should consider this trial

Good fit: Ideal candidates are men aged 45 to 85 with histologically confirmed adenocarcinoma of the prostate and clinical stage T1-4 N0 M0.

Not a fit: Patients with distant metastasis, previous pelvic radiation therapy, or prior prostatectomy will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates and reduce recurrence in prostate cancer patients with pelvic lymph node metastases.

How similar studies have performed: While there have been studies on radiotherapy for prostate cancer, the combination of carbon ion and proton therapy is a novel approach that has not been extensively tested.
