| Summary: | <p>Abstract</p> <p>Background</p> <p>Glandular lesions are often problematic for diagnostic cervical pathology. The survival of patients with adenocarcinoma is significantly poorer than that of patient with squamous cell carcinoma. One reason for this increased risk is the aggressive invasiveness of adenocarcinoma. Therefore additional biomarkers, to supplement morphological diagnosis of adenocarcinoma, are necessary. We have assessed the diagnostic utility of Laminin-5 (Laminin γ2 chain): Lam-5 in the diagnosis of the invasiveness of cervical adenocarcinoma and related glandular lesions.</p> <p>Methods</p> <p>Lam-5 immunohistochemistry was performed on archival specimens from 8 patients with uterine leiomyoma as a negative control group, 6 patients with endocervical gland hyperplasia, 6 patients with adenocarcinoma in situ, 6 patients with microinvasive adenocarcinoma and 24 patients with invasive adenocarcinoma.</p> <p>Results</p> <p>The expression of Lam-5 was not detected in normal mucosa, but was seen along the basement membrane in endocervical gland hyperplasia and adenocarcinoma in situ and was observed in the cytoplasm of tumor cells in microinvasive and invasive adenocarcinoma.</p> <p>Conclusion</p> <p>We conclude that Lam-5 is a useful biomarker in the evaluation of invasiveness in cervical adenocarcinoma.</p> <p>Virtual slides</p> <p>The virtual slides for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/7316562925827381</p>
