HPV-16 Expression and Loss of Cell Differentiation in Primary Bladder Tumors

Abstract

Objective. Primary bladder tumors have a high degree of malignancy. To investigate the expression of human papillomavirus type 16 (HPV-16) in primary bladder tumors and the loss of cell differentiation and to explore the significance of HPV-16 detection, it is expected to be a disease. Treatment provides a theoretical basis. Methods. Fifty-seven patients with primary bladder tumors admitted to our hospital from January 2019 to January 2022 were selected as the research subjects, and they were divided into HPV-related groups according to the human papillomavirus (HPV) infection status ( $n=28$ ) and HPV unrelated group ( $n=29$ ). The general data of patients were collected, the expression of HPV-16 in bladder tissue samples was detected, and the correlation between pathological parameters and HPV-16 expression was analyzed. Results. Among HPV subtypes, HPV 16 subtype accounted for the highest proportion, followed by HPV-18 and HPV-6 subtypes; there was no significant difference in tumor stage (stage 1, stage a, stage 2a) between the HPV-related group and the HPV-unrelated group (stage 1, stage a, and stage 2a). $P>0.05$ ); there was no significant difference in postoperative pathological expression (high expression and low expression) of patients ( $P>0.05$ ); there was no statistical difference in age and gender between HPV-related and HPV-unrelated groups ( $P>0.05$ ), HPV-related group and HPV-unrelated group compared daily regular drinking and smoking status, the difference was statistically significant ( $P<0.05$ ); HPV-16 expression was not correlated with tumor differentiation degree and age of patients ( $P>0.05$ ); the area under the curve (AUC) of HPV-16 for judging primary bladder tumor expression and cellular molecular deletion was 0.891, with a sensitivity of 83.94% and a specificity of 88.57%. Conclusion. HPV-16 is an upper, expressed in primary bladder tumors and will participate in the differentiation and loss of cells, which can provide effective guidance and basis for the diagnosis of primary bladder tumors, which is an important factor for judging the pathological stage and prognosis of patients and can provide a theoretical reference for the formulation of therapeutic measures.
