Puesta al día: estadificación del carcinoma de células renales

Update on staging of renal cell carcinoma. Renal cell cancer or renal adenocarcinoma is the most com- mon malignant renal tumor in adults, with a higher incidence between the fourth and sixth decades of life. It is twice more frequent in men than in women. In Argentina, the estimated incidence is 6.1 cases per 100000 inhabitants per year with a mortality rate of 3.4 cases per 100000 inhabitants per year. Staging is performed using the TNM system of the American Joint Committee on Cancer (AJCC), which has been updated in its seventh edition, (2010) reflecting changes in T, with T2 subdivision (T2a > 7 cm and 10 cm), reclassification of ipsilateral adrenal involvement as T4 if there is contiguous invasion and reclassification of renal vein involvement as T3a. Nodal involvement was simplified to N0 and N1. Keywords. Cancer. Kidney. TNM.
