Background & Objective: High-risk (HR) HPV infection is the major cause of cervical cancer, which is still one of the most common cancers among women. Based on some not-published results, it seems that some of the other HR HPVs might be as important as HPV 16, and 18 in developing high-grade CIN. This study was conducted to determine the relationship between Other HPV and high-grade CIN.Materials & Methods: In this prospective study from 2019 to 2022 (approved by the ethics committee), all women with positive HPV based on the COBAS method were invited to participate in the study (N=646). For all the patients, colposcopy was done, and then the liquid-based samples of women with Other HPV positives were reanalyzed by HPV typing.Results: All the patients who were infected with HPV18 were involved in CIN1. On the other hand, 50% of patients who were infected with HPV18 were involved in CIN2. 50% of patients with HPV45 were involved in CIN2. There is also a significant relationship between HPV31 and CIN3.Conclusion: Because in our study there was a significant relationship between CIN3 and HPV31; and CIN2 with HPV45, and in the COBAS method, HPV31 and HPV45 are only reported under the general title of Other HPV, because of the possibility of the importance of other HPV with high-grade neoplasias, it is recommended to analyze the other HPV with HPV typing. Further studies are needed to confirm our findings.

Background and Objective: Cervical cancer is a common neoplasm in women, and the role of the HPV virus in the development of precancerous and cancerous cells has been established. There exist different strains of the HPV virus with varied functions. In the high-risk HPV strains, the p16 and ki67 proteins play a crucial role in regulating the cell cycle leading to cell proliferation and progression. P16 and ki67 proteins are positive in almost all lesions and indicate a high degree of malignancy. This study aims to investigate the predictive effect of p16 and ki67 on the progression of low-grade intraepithelial lesions to high-grade malignancy.Methods: P16 and ki67 were measured on CIN1 lesions, and during the average two-year follow-up period, the outcome of positive cases was investigated. A total of 106 referred patients between the age of 15 to 75 years were examined from April 2015 to March 2019.Results: Among the patients with progression of CIN1 to CIN2 and other severe lesions, p16 was positive in 14 cases (60.9%), and a significant difference between groups with positive and negative markers in the progression or regression of lesions was noticed. Ki67 frequently occurs in CIN2 and other severe lesions.Conclusion: The use of p16 and ki67 as predictive markers is still under debate. In countries like the United States, these are not yet used separately for prediction but are being used in combination together. The authors of this study strongly recommend the conduction of further studies to assess the role of p16 in association with other markers and within a larger population so as to apply the functional role of p16 and ki67 in the clinical setting thereby effectively preventing it.
