Abstract:
OBJECTIVETo study the diagnostic value of SATB2, together with CK7 and CK20, in colorectal cancer.
METHODSImmunohistochemical study for SATB2, CK7 and CK20 was carried out in 210 cases of colorectal cancer tissue, 100 cases of non-colorectal cancer tissue, 90 cases of lymph node metastases and 50 cases of normal colorectal mucosa.
RESULTSThe sensitivity and specificity of CK20+/CK7- immunophenotype for diagnosis of colorectal adenocarcinoma were 78.1% and 92.0%, respectively. When triple markers were used, the immunophenotype CK20+/CK7-/SATB2+ had a sensitivity of 57.1% and a specificity of 98.0%. When combining the immunophenotype of SATB2+/CK7- or CK20+/CK7-, the sensitivity was 85.7% and specificity was 90.0%.
CONCLUSIONSA panel of immunohistochemical markers SATB2, CK7 and CK20 could increase the specificity for diagnosis of colorectal adenocarcinoma significantly. SATB2 is considered as a useful adjunct in this respect.
