Baseline tumor volume in assessing prognosis of patients with intermediate-risk synchronous metastatic renal cell carcinoma

None of the baseline volumetric parameters is an independent prognostic factor in patients with intermediate MSKCC risk mRCC with≤3 IMDC factors receiving sunitinib. Only CN status correlated significantly with prognosis. None of the baseline volumes nor TB by Response Evaluation Criteria in Solid Tumors was associated with CN status, suggesting that extent of disease had no significant influence on the decision to perform surgery.
