Cervical cancer is the fourth most common type of cancer in women worldwide. It is widely accepted that the main cause of cervical cancer, especially in underdeveloped countries like Pakistan, is the infection caused by the human papillomavirus (HPV). The current screening and diagnostic methods face several challenges in accurately detecting the various types of lesions caused by HPV. Therefore, the present study was conducted to assess the effectiveness of p16 immunohistochemistry (IHC) analysis as a diagnostic method in samples of cervical biopsies. One hundred cervical biopsy samples were obtained from female patients across various age groups (> 20- ≤ 30, > 31- ≤ 40, > 41- ≤ 50, > 51- ≤ 60 years). These samples were subsequently prepared for subsequent examination. All samples were analyzed using automated tissue processing followed by Hematoxylin and Eosin (H & E) staining, and p16 IHC tumour marker staining. The H & E slides showed changes in normal cervical tissues, while four cervical abnormalities were identified statistically significant using p16 marker including chronic cervicitis, nabothian cyst formation, cervical intraepithelial neoplasia, and cervical cancers (P value 0.014). Furthermore, among females of different age groups (> 31- ≤ 40, > 41- ≤ 50, > 51- ≤ 60 years) were found statistically significant suffering from cervical cancer (P value 0.04), HPV with cervical cancer (P value 0.01), HPV with cervical intraepithelial neoplasia (P value 0.01). Based on the available data, it can be inferred that the incorporation of the p16 tumor marker may be a valuable method for detecting high-risk HPV in cervical biopsies samples.
