Whether patients with stage III clear cell renal cell carcinoma(ccRCC) should receive adjuvant targeted therapy or not is still on debate. The investigators invented a assay consisting of 5 CpGs: cg00396667（PITX1）, cg18815943 （FOXE3）, cg03890877（TWF2）, cg07611000 （EHBP1L1）and cg14391855（RIN1）that was successfully categorise patients with stage III clear cell renal cell carcinoma into high-risk and low-risk groups with Harzard Ratio(HR) of 4.93. Here the investigators randomly assign assay-defined high risk patients of locally advanced ccRCC into adjuvant targeted therapy group and observation group.Disease free survival and overall survival are the end points of observation.
