Clinical comparison between vascular and avascular renal cell carcinoma.
Of 72 patients with renal cell carcinoma 19 were found to have an angiographic avascular neoplasm. These avascular tumors have a lower incidence of vein and capsule invasion than vascular tumors. Among these avascular cancers papillary adenocarcinoma was the predominant histologic pattern. Patients with papillary tumors seem to have a lower clinical stage and increased survival rate than patients with non-papillary tumors.
