Associations between the expression of SCCA, MTA1, P16, Ki-67 and the infection of high-risk HPV in cervical lesions.

ABSTRACT: 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<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.

Project description:BACKGROUND:Human Papilloma Virus (HPV) DNA tests are highly sensitive and can triage women with mild lesions, improving the prognosis and diagnosis of cervical lesions. However, additional efficient strategies should be developed to improve the specificity of these tests. METHODS:This study aimed to evaluate the clinical value of HPV DNA load in improving the diagnosis and prognosis of cervical lesions by p16/Ki-67 testing. Histological samples were collected from 350 women with HR-HPV genotyping and analyzed by qRT-PCR. Immunohistochemical staining was used to assess p16 and Ki-67 expression and clinical performance characteristics were calculated. RESULTS:Of the cases, 271 had detectable HR-HPV infection, in which HPV-16 was most prevalent (52.0%), followed by HPV-58 (22.5%). P16/Ki-67-positivity increased with histological severity but not for HR-HPV infection. Amongst the 13 HR-HPV genotypes, only HPV-16 (P = 0.016) and HPV-58 (P = 0.004) viral loads significantly correlated with lesion severity. The P16/Ki-67/HPV DNA load co-test indicated an increased sensitivity for the detection of cervical intraepithelial neoplasia (CIN) lesions compared to p16/Ki-67 staining in HPV-16 and/or 58 positive cases. Viral load did not improve the sensitivity of p16/Ki-67 co-test in non-HPV-16 or 58 positive cases. The clinical performance of the p16/Ki-67/HPV DNA load co-test was limited for the prediction of the outcome of CIN1 lesions. However, amongst the 12 HPV-16 and/or 58 positive CIN2 cases in which return visit results were obtained, the behavior of the lesions could be predicted, with a sensitivity, specificity, positive prediction rate (PPV), and negative prediction rate (NPV) of 0.667, 1, 1 and 0.5, respectively. CONCLUSION:Combination of the assessment of HPV DNA load with the intensity of p16 and Ki-67 staining could increase the sensitivity of CIN lesion diagnosis and predict the outcome of CIN2 in patients with a HPV-16 and/or 58 infection.

Project description:ImportanceAs cervical cancer screening transitions to primary human papillomavirus (HPV) testing, effective triage and management of HPV-positive women is critical to avoid unnecessary colposcopy referral and associated harms while maintaining high sensitivity for cervical precancer. Triage with p16/Ki-67 dual-stain (DS) testing has shown high sensitivity and specificity for detection of cervical precancers; however, longitudinal studies are needed to determine the long-term risk of precancer following a negative DS result.ObjectiveTo evaluate the longitudinal performance of p16/Ki-67 DS triage for detection of cervical precancer in HPV-positive women over 5 years of follow-up in the context of clinical management thresholds.Design, setting, and participantsProspective cohort study of HPV-positive women 30 years or older undergoing routine cervical cancer screening in 2012 with HPV and Papanicolaou (hereinafter "cytology") co-testing within the Kaiser Permanente Northern California health care system. Follow-up of medical records was conducted through 2017.ExposuresAll p16/Ki-67 DS testing was performed on residual SurePath material, and slides were evaluated for p16/Ki-67 positivity.Main outcomes and measuresHistological end points were ascertained from the clinical database through 2017. We estimated 5-year cumulative risks of cervical intraepithelial neoplasia grades of 2 or worse (≥CIN2) or grades 3 or worse (≥CIN3) by baseline DS and cytology at yearly intervals using Logistic Weibull models. Risks were compared with clinical management thresholds for colposcopy referral and a 1-year return interval.ResultsAmong the 1549 HPV-positive women in this study, the mean age at enrollment was 42.2 years, and the median follow-up time was 3.7 years (range, 0.2-5.4 years). Positive DS results were associated with significantly higher cumulative 5-year risks of ≥CIN2 compared with abnormal cytology (31.0%; 95% CI, 27.2%-35.3% vs 25.0%; 95% CI, 21.7%-28.7%; P = .03). Women with DS-negative findings had significantly lower 5-year risks of ≥CIN2 compared with women with normal cytology (8.5%; 95% CI, 6.5%-11.1% vs 12.3%; 95% CI, 9.8%-15.4%; P = .04). In DS-negative women, the risks of both ≥CIN2 and ≥CIN3 remained below the colposcopy referral threshold for all 5 years, crossing the 1-year return threshold at 3 years.Conclusions and relevanceTriage with p16/Ki-67 DS provides better long-term risk stratification than cytology over 5 years. The low risk of cervical precancer in p16/Ki-67 DS-negative women permits safe extension of follow-up intervals for 3 years.
