Expression of Oct-4, p53, p16 and ki-67, with HPV associated precancer and cancer of the cervix

The pathology of cervical HPV infection is detected by three types of epithelial-mesenchymal spheroidal structures: reparative, neoplastic and cancerous involved in reparation processes and in tumor growth. Cancer spheroids are different from neoplastic not only larger in size but also a tendency to merge, and high expression of p53. Expression of tumor markers p53, p16 and Ki-67 could be used in the early differential diagnosis of precancer and squamous cell carcinoma of the cervix.
