ABSTRACT Objective
?/p>
To investigate the clinical value of differentiation of the papillary
thyroid carcinoma

and human bone marrow endothelial cell-1
?/p>
HBME-1
?/p>
. Methods
?/p>
The parafin sections
of 180 cases with PTC and 190 cases with the benign thyroid nodules were retrospectively analyzed.
The levels of Ki67
?/p>
TTF-1
?/p>
HBME-1 and HER-2/neu were determined immunohistochemically.
Results
?/p>
The positive rates of the expressions of 4 markers were higher in PTC specimens than in the
benign thyroid nodules specimens
?/p>
P=0.000
?/p>
. When using a single marker
?/p>
the detection of HER-
2/neu had the most sensitivity
?/p>
79.4%
?/p>
and that of HBME-1 the most specificity
?/p>
96.8%
?/p>
. The
detection combined with Ki67
?/p>
HER-2/neu and HBME-1 had the most sensitivity
?/p>
89.8%
?/p>
. The
detection combined with HER-2/neu+ TTF-1 and HER-2/neu+TTF-1+HBME-1 had the same
specificity
