A Study to Evaluate Immune Markers in Patients with Renal Cell Cancer


About this study

The objectives of this study are to measure baseline immune markers and peripheral blood mononuclear cell (PBMC) characteristics in RCC patients, to measure post-ablative therapy immune markers and PBMC characteristics, to compare effects of SBRT versus PCA on immune markers and PBMC characteristics, and to assess impact of post-treatment markers on time to disease progression and levels of markers at time of disease progression.
