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

Description

This is a pilot study to assess acute toxicity in patients receiving flank irradiation using proton therapy for renal tumors.Patients with renal tumors including Wilms and clear cell sarcoma of the kidney (CCSK) are treated with multimodality therapy which may include surgery, chemotherapy, and radiation. While long-term disease control is excellent, these patients remain at risk for early and late toxicities partially from radiation. There have been no significant changes to traditional photon radiation fields, which encompass the post-operative bed, anterior abdomen, and vertebral body. Proton beam radiation using pencil beam scanning, which is characterized by Bragg peak dose deposition and high conformality of dose to target regions, is ideally suited to treat the retroperitoneum. This pilot study evaluates pencil beam scanning proton therapy (PBS-PT) to: * result in low acute gastrointestinal toxicity in patients receiving radiation therapy for renal tumors as measured by laborat
