Abstract EN
Background: Colorectal carcinoma (CRC) is a common malignancy in Iraq and carries a high mortality rate.
It has been shown that CRCs express high level of beta‑human chorionic gonadotropin (β‑HCG) as detected by immunohistochemistry.
Objectives: The aim of this study was to assess the expression of β‑HCG in CRC and to study the association between β‑HCG expression and pathological prognostic parameters.
Materials and Methods: This study was carried out on 35 colonic specimens consisting of 30 CRC selected from files of Pathologic Laboratory of Al‑Kadhymia Teaching Hospital and Teaching Laboratories of the Medical City, Baghdad.
Paraffin blocks were cut sections stained with H and E stain and sections for streptavidin‑biotin immunohistochemical staining using monoclonal antibody against β‑HCG.
Immunohistochemical sections were examined for positive or negative staining and positivity assessed as: occasional, focal, and diffuse tumors.
Results: Of the 30 CRCs, 60% were male and 40% were female.
The most common site of large bowel malignancy was the rectum 13 (43.3%).
Most of the tumors were moderately‑differentiated adenocarcinoma (83.3%).
More than half of the cases were Stage T3, followed by Stage T2, then Stage T4, 3 cases (10%), and no case in Stage T1.
Lymph node metastases were found in 19 cases (63.3%).
Twelve cases (40%) of CRC show immunoreactivity to β‑HCG.
β‑HCG expression was more frequent in the left side of the large bowel and more common in poorly‑differentiated adenocarcinoma (80%).
β‑HCG was more positive in Stage T4, and there was significant association with lymph node metastasis.
Conclusion: Expression of β‑HCG in CRC is not an infrequent phenomenon, and no stain was demonstrated in benign and normal colonic specimens, while β‑HCG expression associated with poor differentiation, greater local invasion, and regional lymph node metastasis.
