Stereotactic radiation therapy for patients with 6 to 10 metastatic sites

OLIGO-10: Stereotactic Ablative Radiation Therapy for Metastatic Patients (6-10 Metastases): A Prospective Phase II Single-Arm Trial

Phase 2 Interventional National Medical Research Radiological Centre of the Ministry of Health of Russia · NCT06856603

This study is testing a new type of targeted radiation therapy for people with metastatic cancer who have 6 to 10 tumor sites to see if it can help them live longer.

What this trial studies

This study evaluates the safety and effectiveness of stereotactic ablative radiation therapy in patients with metastatic cancer who have between 6 to 10 metastatic sites. Patients will undergo advanced imaging and dosimetric planning to target their tumors with high precision radiation. The treatment aims to improve overall survival in a patient population that has not been extensively studied in previous trials. The approach is based on emerging evidence suggesting benefits of radiation therapy in oligometastatic disease.

Who should consider this trial

Good fit: Ideal candidates include patients with persistent or progressive cancer disease and 6 to 10 metastases who are not eligible for surgical resection.

Not a fit: Patients with ECOG status 4, de novo metastatic disease, or those who have had previous radiation therapy for any metastatic site may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates for patients with multiple metastatic sites.

How similar studies have performed: Other studies have shown success with stereotactic ablative radiation therapy for fewer metastatic sites, but this specific approach for 6 to 10 metastases is novel.
