The application of detection technologies for human papillomavirus (HPV) has increased the resection rate for cervical intraepithelial neoplasia and early cervical cancer types. However, a large number of patients still present with advanced cervical cancer upon diagnosis. Therefore, to find a marker for the early diagnosis of cervical cancer, the present study investigated the expression profiles of squamous cell carcinoma antigen (SCCA), tumor metastasis related factor-1 (MTA1), the multiple tumor suppressor gene P16, and the nucleus-associated antigen Ki-67 in cervical lesions, and evaluated the association between the four proteins and the infection of high-risk (HR)-HPV in cervical lesions. The rate of SCCA expression gradually increased with the progression of cervical lesions, but the increase in SCCA expression levels from low-grade squamous intraepithelial lesions (LSIL) to high-grade squamous intraepithelial lesions was not significant (P=0.197). The positive rate of MTA1 expression gradually increased with the development of cervical lesions, but the increase from chronic cervicitis to LSIL was not significant (P=0.258). The positive rates of P16 and Ki-67 expression exhibited significant increasing trends with the progression of cervical lesions. The expression ratio of SCCA between HR-HPV infection and non-infection groups was not statistically significant (P=0.38), but the expression ratios of MTA1, P16 and Ki-67 between HR-HPV infection and non-infection groups were statistically significant (P&lt;0.05). These results demonstrated that the expression of SCCA, MTA1, P16 and Ki-67 increased gradually with the severity of cervical lesions. In addition, there was a positive association between the expression levels of MTA1, P16 and Ki-67 and the infection of HR-HPV in cervical lesions. Therefore, SCCA, MTA1, P16 and Ki-67 may be used to enhance the diagnostic accuracy for cervical lesions.
