Objective:
To study the diagnostic value of SATB2, together with CK7 and CK20, in colorectal cancer.
Methods:
Immunohistochemical 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.
Results:
The 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%.
Conclusions:
A 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.
