Observational study of SBRT for patients with rare tumors and oligometastases
Official title: Prospective Observational Basket Study of Stereotactic Body Radiation Therapy for OligoMetastatic Patients From Rare Tumors: the PROMPT Study
Run by Istituto Clinico Humanitas · NCT05903261 · Data updated 2026-11-12
This study is testing how well a special type of radiation therapy works for patients with rare tumors that have spread to a few other places in the body.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients with histologically confirmed rare solid tumors and oligometastases who meet specific eligibility criteria.
✕Probably not a fit
Patients who have previously received radiation treatment to the same metastatic site or have contraindications to SBRT may not benefit from this study.

What this trial studies
This prospective observational study investigates the effectiveness and safety of stereotactic body radiation therapy (SBRT) in managing oligometastases from rare tumors. It aims to identify differences in treatment efficacy and toxicity across various cancer types, providing valuable insights into SBRT's role in these contexts. The study includes patients with a limited number of metastases and evaluates the potential for improved treatment outcomes through localized radiation therapy. By focusing on rare tumors, this research seeks to enhance treatment options for patients who often face limited choices.
Why it matters
Potential benefit: If successful, this study could offer a promising treatment option for patients with rare tumors and oligometastases, potentially leading to better local control and outcomes.
How similar studies have gone: While there is limited data on SBRT for rare tumors, previous studies have shown promising results for SBRT in common solid tumors, indicating potential for success in this novel application.
