p27kip1 expression in human breast cancers

GradeNo. of tumors expressing p27kip1% tumors expressing p27kip1
  • p27kip1 expression in human breast tumors ranging from grade I to III. The number of tumors positive and negative for nuclear p27kip1 staining are shown under + or −, respectively. The number of tumors examined for each grade is shown under total. The total number of tumors examined is regarded as 100%, and the percentage of nuclear p27kip1 staining positive and negative tumors is shown as percentage under + or −, respectively for each graded group of tumors.
