Proton therapy for children with renal tumors

Official title: Pilot Study of Pencil Beam Scanning Proton Beam Radiation Therapy in Patients With Renal Tumors

Run by Children's Hospital of Philadelphia · NCT03810651 · Data updated 2026-11-12

This study is testing a new type of proton therapy for children with kidney tumors to see if it can reduce side effects from treatment while still being effective.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients under 30 years old diagnosed with Wilms tumor or clear cell sarcoma of the kidney requiring radiation therapy.

Probably not a fit

Patients who have previously received radiation therapy to the affected area or are pregnant or breastfeeding may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot study evaluates the use of pencil beam scanning proton therapy in patients with renal tumors, including Wilms tumor and clear cell sarcoma of the kidney. The approach aims to minimize acute gastrointestinal toxicity associated with radiation therapy while maintaining effective treatment. Patients will undergo assessments of health-related quality of life and laboratory evaluations to measure toxicity levels. The study also compares the radiation doses to organs at risk using this advanced proton therapy technique versus traditional photon radiation.

Why it matters

Potential benefit: If successful, this approach could significantly reduce radiation-related side effects in young patients with renal tumors.

How similar studies have gone: Other studies have shown promise with proton therapy in reducing toxicity, but this specific approach using pencil beam scanning is relatively novel.
