The overall agreement between p16 and consensus diagnosis was 96.1% (Kappa=0.90, P<0.001), which were higher than those of Ki67 and consensus diagnosis. All of the p16 positive cases were also positive for Ki67, but none of the p16 positive cases were negative for Ki67 (table 1). The agreement between Ki67 and p16 was higher than Ki67 and Human papillomavirus (HPV) is a possible carcinogenetic factor in oral squamous cell carcinoma (OSCC). Previous studies have reported the prevalence of HPV in patients with OSCC. However, the association between HPV and OSCC remains controversial. The present study aimed to clarify the association between HPV infection, p16 protein expression Introduction: p16 INK4a immunohistochemistry (IHC) is widely used to facilitate the diagnosis of human papillomavirus (HPV)-associated neoplasia, when ≥70% of cells show strong nuclear and cytoplasmic positivity. In this study, we aim to compare partial expression patterns that do not fulfill the above criteria and seek biological implications in laryngeal squamous cell carcinoma (LSCC). There was no statistically significant difference in mean OS (56.7 vs 58.7 months) (P = .88), mean LRC (65.3 vs 76.8 months) (P = .52), mean DFS Six of the p16-positive tumors had enough tissue to perform ISH for HPV, and only 1 of those tumors was HPV-positive. All 13 of the p16-negative tumors with tissue available for ISH were found to Pap cytology, p16/Ki-67 immunostaining, and HPV testing were performed on all women. Positive test results triggered colposcopy referral, except for women younger than 30 years with only positive HPV test results. Presence of CIN2+ on adjudicated histology was used as the reference standard. Two-sided bias-corrected McNemar P values were The expressions Ck7 positive and Ck20 negative are commonly observed in patients with lung cancer. The mortality of lung cancer is high around the world. The risk factors like aging and hereditary factors intensify the situation. Cell cytokeratin involvement plays a major role in the development of tumor or lung cancer. The .gov means it's official.
