          Abstract

          BACKGROUND: The reduced expression of CD10 may be related to unfavorable prognosis of patients with colorectal carcinoma. The authors analyzed the tissue immunostaining of CD10 protein in colorectal carcinoma and its relationship to clinicopathologic features. METHOD: In 130 patients submitted to colorectal carcinoma surgery, a tissue microarray block was obtained from the tumor and adjacent non-neoplastic mucosa and submitted to immunohistochemistry with monoclonal antibody CD10. The immunostaining was evaluated by semi-quantitative method, with stained cell count in percentage. The results were related to the location, anatomopathological features, presence of lymph node and hepatic metastases and TNM staging of the colorectal neoplasm. The statistical analysis was performed with the Mann-Whitney, Kruskal-Wallis and Fisher exact tests. RESULTS: The expression of CD10 marker was higher in colorectal tumor tissue than in adjacent non-neoplastic mucosa (p<0.0001) and was higher than in exophytic lesions (p=0.04). The expression of CD10 protein was not associated with other clinical and pathological aspects of colorectal neoplasm. CONCLUSIONS: The expression of CD10 protein was more intense in tumor tissue of colorectal carcinoma than in adjacent non-neoplastic mucosa and was related to the exophytic appearance of the tumor.

          INTRODUÇÃO: A expressão reduzida de CD10 pode estar relacionada com prognóstico desfavorável de doentes com carcinoma colorretal. Analisou-se a imunoexpressão tecidual da proteína CD10 no carcinoma colorretal e sua relação com os aspectos clinicopatológicos. MÉTODO: Em 130 doentes operados por carcinoma colorretal, um bloco de tissue microarray foi obtido do tecido neoplásico e da mucosa não neoplásica adjacente e submetido ao estudo imuno-histoquímico com anticorpo monoclonal CD10. Avaliou-se a imunoexpressão por método semiquantitativo, com contagem do percentual de células coradas. Os resultados foram relacionados com a localização, aspectos anatomopatológicos, presença de metástases linfonodais e hepáticas e estadiamento TNM da neoplasia. O estudo estatístico foi realizado com os testes de Mann-Whitney, Kruskal-Wallis e exato de Fisher. RESULTADOS: A expressão do marcador CD10 foi maior no tecido do carcinoma colorretal do que na mucosa não neoplásica adjacente (p<0,0001) e foi maior nas lesões exofíticas (p=0,04). A expressão da proteína CD10 não apresentou relação com os demais aspetos clínicos e patológicos da neoplasia colorretal. CONCLUSÕES: A expressão da proteína CD10 foi mais intensa no tecido neoplásico do carcinoma colorretal do que na mucosa não neoplásica adjacente e relacionou-se com o aspecto exofítico do tumor.

          Expression of CD10 by stromal cells during colorectal tumor development.

          CD10 is a cell surface metalloprotease expressed by a variety of normal cell types, including lymphoid precursor cells, germinal center B lymphocytes, and some epithelial cells. We noticed that stromal cells of some cancers are positive for CD10. In this study, we investigated the role of CD10 produced by the stromal cells of colorectal neoplasms in the progression of colorectal neoplasms. Immunohistochemical examination of CD10 and p53 was performed in 169 colorectal epithelial neoplasms representing various stages of carcinogenesis. The results were correlated with the morphologic characteristics of the neoplasms. There was no expression of CD10 in the stromal cells of normal colorectal tissue. CD10-positive stromal cells were present adjacent to the tumor cells in 16 of 73 adenomas with mild or moderate dysplasia. More frequent expression of CD10 by the stromal cells was detected in adenomas with severe dysplasia (12 of 17), intramucosal carcinomas (10 of 16), and invasive carcinomas (50 of 63) than in adenomas with mild or moderate dysplasia (P 10% of the stromal cells was detected only within the area of the invasive growth front of invasive carcinomas, not in adenomas and in only 1 of the intramucosal carcinomas. The difference between invasive and non invasive tumors was significant (P < 0.0001). The stromal expression of CD10 was significantly associated with the accumulation of p53 and a larger tumor size. These results indicate that CD10 expression is an integral part of colorectal carcinogenesis. CD10 expression seems to contribute to the invasion and thus probably facilitates metastasis.

            CD10 expression in colorectal carcinoma correlates with liver metastasis.

            If it were possible to identify the features of primary colorectal carcinoma that were associated with liver metastasis, these features could be used as predictors of liver metastasis. From January 1995 to December 1997, 648 consecutive cases of colorectal carcinoma were recorded at the Department of Surgery, National Cancer Center Hospital, Tokyo, Japan. We evaluated clinicopathologic and immunohistochemical factors (age, gender, tumor location, gross type, size, histologic type, dedifferentiation of invasive front, depth of invasion, lymphatic invasion, venous invasion, lymph-node metastasis, and expression of CD10, MUC2, and human gastric mucin) in 505 of these patients who had undergone resection of T2/T3/T4 colorectal carcinomas to clarify the correlation between these factors and liver metastasis. Liver metastases, including unresectable, were detected in 122 patients (24 percent), all of whom had been followed for at least five years. Univariate analysis revealed that liver metastasis was significantly associated with tumor size, histologic type, dedifferentiation of invasive front, depth of invasion, lymphatic invasion, venous invasion, lymph-node metastasis, and CD10 expression. Multivariate analysis revealed that invasion deeper than the subserosa, venous invasion, lymph-node metastasis, and CD10 expression were significantly associated with liver metastases. CD10 expression in colorectal carcinoma is a good predictor of liver metastasis.

              CK20 and CK7 protein expression in colorectal cancer: demonstration of the utility of a population-based tissue microarray.

              The ability to use archival tissue to test externally valid hypotheses of carcinogenesis is dependent on the availability of population-based samples of cancer tissue. Tissue microarrays (TMAs) provide an efficient format for developing population-based samples of tissue. A TMA was constructed consisting of archival tissue from patients diagnosed with invasive colorectal cancer in the state of Hawaii in 1995. The population representativeness of the TMA was evaluated by comparing patient and clinical characteristics of TMA cases to that of all cases of colorectal carcinoma diagnosed statewide in 1995. Cytokeratin 20 (CK20) and cytokeratin 7 (CK7) immunohistochemistry was used to validate the utility of the TMA, and the expression of these proteins was correlated with patient and tumor characteristics. The TMA comprised tissue specimens from 286 patients representing 47% of all invasive cases diagnosed statewide in 1995. TMA cases were comparable to all invasive colorectal cases statewide with respect to age, sex, race/ethnicity, anatomic site, and survival. There were some differences between TMA cases and all cases with respect to tumor stage, histological classification, and treatment. There were significant differences in the relative expression of CK20 and CK7 proteins between malignant and normal tissues and by tumor stage. Advanced cancers were more likely to have CK20+/cytokeratin 7+ (CK7+) profiles than early-stage cancers, which were predominantly CK20+/cytokeratin 7- (CK7-). CK7+ expression was not correlated with anatomic location of carcinomas. This well-characterized TMA offers a powerful tool for testing hypotheses regarding colorectal carcinogenesis, including the identification of potential markers of neoplastic development and progression.
