†Symptoms: including any tumor-related symptoms; incidental finding indicates a symptomless tumor; −, no data. ǁpT Stage: classification by AJCC 2016 TNM Staging System. §Node Status: nodal status at time of surgery; −, no lymph node was removed; Neg, negative; Pos, positive. A lymph node metastasis that developed during the follow-up period is listed in the” Metastasis” column. *Metastasis: either found earlier or at the same time with the primary renal tumor, or during the follow-up period; Bone-U, bone, exact location is unknown; −, no data; R, recurrence; LN, lymph node. ¶Status: DOD, died of disease; LTF, patient is deceased, but lost to follow-up; NED, no evidence of disease; NCRD, not a cancer-related death; AWD, alive with disease; −, no data
