Risk factors and prognostic implications for pathologic upstaging to T3a after partial nephrectomy

Abstract

Larger tumor size and increased age are associated with pathological upstaging to T3a for clinical T1 tumors treated with partial nephrectomy. Steps to improve identification of occult pT3a disease are necessary as its occurrence significantly increased the likelihood of a PSM, both in a high-volume multicenter cohort, as well as, a national data registry.
