Cervical Cancer

Cervical cancer, which develops in the tissues of the cervix, can be classified into two types: squamous cell carcinoma and adenocarcinoma. Smoking and human papillomavirus (HPV) infection are the key risk factors. Several studies have led the discovery of a range of biomarkers including several polymorphisms, microRNAs, mRNA and serum biomarkers.

One of the challenges in cervical cancer is to distinguish between squamous cell carcinoma (SCC) from adenocarcinoma (AEC) 6 In a recent study, Li et al. showed that a combination of cytokeratin 5/6 (CK5/6), p63, p40 and MUC5AC are useful in differentiating cervical adenocarcinoma from cervical squamous cell carcinoma using immunohistochemistry 7
