Stereotactic Body Radiation Therapy in Treating Patients With Oligometastatic Renal Cell Carcinoma

Metastatic Renal Cell Carcinoma Clinical Trial

Official title: Definitive Radiation-Based Treatment Strategy for Oligometastatic and Low Metastatic Burden Renal Cell Carcinoma in Lieu of Systemic Therapy

Status Suspended

Clinical Trial Summary

This phase II trial studies how well stereotactic body radiation therapy works in treating patients with kidney cancer that has spread to other places in the body (metastatic). Stereotactic body radiation therapy 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.

Clinical Trial Description

PRIMARY OBJECTIVES: I. To evaluate the feasibility definitive radiation therapy (RT) (such as stereotactic body radiation therapy [SBRT]) as a treatment strategy for oligometastatic renal cell carcinoma (RCC) in lieu of systemic therapy. II. To estimate the progression free survival (PFS) after study enrollment utilizing a strategy of definitive local treatment to all sites of disease in oligometastatic and low metastatic burden RCC as measured by Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). III. To determine the systemic therapy free survival after study enrollment SECONDARY OBJECTIVES: I. To determine the effect of definitive RT (SBRT) on cellular replication and death, measured by ki-67 staining and others. (Required in Cohort A, but optional in Cohort B) II. To estimate the overall survival at 12 months after study enrollment. III. To estimate the freedom from new lesion development at 12 months. IV. To determine the treatment related toxicities associated with definitive RT as part of definitive local therapy for oligometastatic and low volume metastatic RCC. EXPLORATORY OBJECTIVE: I. To determine the association of translational biomarkers including peripheral blood markers and tissue markers with patient outcomes. OUTLINE: Patients undergo SBRT over 1 day to 3 weeks based on the judgment of the treating radiation oncologist. If the disease spreads to a new lesion that can be treated with local therapy, patients may repeat SBRT over 1 day to 3 weeks based on the judgment of the treating radiation oncologist. Patients may undergo blood sample collection throughout the trial, as well as a tumor biopsy on study. Patients also undergo computed tomography (CT), positron emission tomography (PET)/CT, and/or magnetic resonance imaging (MRI) throughout the trial. After completion of study treatment, patients are followed up every 12 weeks for 1 year, and then every 18 weeks thereafter. ;
