A Pilot Study of Spatiotemporal SBRT for Poly-Metastatic Cancer
City of Hope Medical Center
Summary
This clinical trial evaluates the safety and effectiveness of spatiotemporal stereotactic body radiation therapy (ST-SBRT) in treating patients with solid tumors that have spread to other parts of the body (polymetastatic). SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. ST-SBRT is designed to deliver radiation directly to the core of the tumor, while keeping the radiation exposure of the area around the tumor at minimal dosage.
Description
PRIMARY OBJECTIVE: I. To conduct a first evaluation of the toxicity and efficacy of ST-SBRT, targeting polymetastatic lesions as small as 2.0 cm. SECONDARY OBJECTIVES: I. To describe feasibility using: Ia. Percentage of patients with screen failure; Ib. Number of ST-SBRT fractions given per subject; Ic. Percentage of treatment fractions that require adaptation. II. To summarize: IIa. Percentage of subjects with clinical response in non-irradiated lesions (abscopal effect); IIb. Duration of earliest clinical response; IIc. Frequency of late toxicity; IId. 1-year overall survival; IIe. 3-m…
