Only 53 % of tumors with co-expression of MMP-14 and CD44 were of serous histology versus 72 % in the no/single-expression group; clear cell histology was 16 % versus 8 % in the co-expression group; and unspecified histology was 10 % versus 4 % in the adenocarcinoma group. Here, MMP14 is linked to adenocarcinoma.
