Age=age at diagnosis and primary surgery. F=female, M=male. Clinical outcome: Years=observation time. X indicates outcome at follow up, which was categorized as NED=alive, no evidence of disease. AWD=alive with disease. DWD=dead with disease. DOD=dead of disease. ICC findings: The categories were as follows: 0=<1% positive cells, 1+=1–24% positive cells, 2+=25–75% positive cells, 3+=>75% positive cells.
