Table 2 Comparison of tissue microarray and whole slide scores for matched tumors

From: Ki-67 in endometrial cancer: scoring optimization and prognostic relevance for window studies

 

Tissue microarray

Whole slide

Number of matched tissue microarray and whole slide sections

n=67a

 

Median Ki-67 score (interquartile range)

19% (10–31%)

32% (21–47%)

Number of sections in which the tissue microarray and whole section scores were within 10% of each other

n=28 (42%)

 
  1. aTissue microarrays were constructed from the same blocks as those used to cut whole slides and therefore have overlapping areas of tumor.
