Abstract

Purpose: A recent multi-institutional analysis of 995 patients treated for renal cell cancer questioned the relationship between tumor size and the synchronous metastasis rate. We revisited the hypothesis that metastatic potential is unrelated to tumor size. Materials and Methods: We tested the relationship between tumor size and synchronous metastasis in 22,204 patients with T1a and T1b renal cell cancer diagnosed and/or treated with nephrectomy for clear cell, papillary or chromophobe histological subtypes in 1 of 9 Surveillance, Epidemiology and End Results registries between 1988 and 2004. Results: In the study population the synchronous metastasis rate was 9.6%, including 5.6% vs 14.2% for T1a vs T1b. Stratification by 1 cm tumor size intervals revealed that the rate increased with increasing tumor size, that is 4.8% at 1.0 cm or less, 4.2% at 1.1 to 2.0 cm, 4.9% at 2.1 to 3.0 cm, 7.1% at 3.1 to 4.0 cm, 12.1% at 4.1 to 5.0 cm, 13.3% at 5.1 to 6.0 cm and 18.4% 6.1 to 7.0 cm (chi-square trend p
