1

What are the types of Kidney cancer? Incidence?

Clear cell (80%),
Papillary (12%),
Chromophobe (5%),
Other (3%): oncocytic, collecting duct, medullary and unclassified.

2

Histologic and molecular features of Clear Cell, Papillary and Chromophobe?

Clear cell: compact nests of cells with clear cytoplasm, del 3p, VHL hypermethylation, 5q+, 8p-, 9p-, 14q-
Papillary: variable portions of papillae, tubulopapillae and tubules, trisomy 7 & 17. y-, 12+, 16+, 20+, rare MET mutations
Chromophobe: large polygonal cells with reticulated cytoplasm, atypical nuclear with perinuclear halo, eosinophilic cytoplasm, loss of chromosome Y, 1, 2, 6, 10, 13, 17 & 21

-nuclear differentiation (Furhman grade)
-performance status (ECOG)

5

Staging workup for RCC?

optional: bone scan & MRI brain
