ABSTRACT
<p><b>OBJECTIVE</b>To study the expression and significance of PLAC1/CP1 genes in patients with primary colorectal carcinoma.</p><p><b>METHODS</b>The expression of PLAC1/CP1 genes in 97 cases of colorectal carcinoma was studied using tissue chip technology and immunohistochemistry.</p><p><b>RESULTS</b>The rate of PLAC1/CP1 proteins expression in the cases studied was 56.7% (55/97), with 27.8% (27/97) being nuclear staining and 43.3% (42/97) being cytoplasmic staining. The percentage of expression was higher in women than in men (χ(2) = 6.567, P = 0.010). The expression in poorly differentiated colorectal carcinoma was significantly higher than that in the well or moderately differentiated carcinoma (χ(2) = 8.321, P = 0.016). The expression was also significantly higher in stage TNM III or IV tumors than in stage TNM I or II tumors (χ(2) = 18.726, P = 0.000). The rate was higher in cases with lymph node metastasis than in those with negative lymph nodes (χ(2) = 17.407, P = 0.000), and was higher as the number of metastasis increasing (χ(2) = 22.632, P = 0.000).</p><p><b>CONCLUSION</b>The expression of PLAC1/CP1 genes correlates with various clinical and pathologic parameters. It carries prognostic significance and may represent a potential target for immunotherapy.</p>
