Extended HPV typing test performed better predict value for CIN2+ among elderly women in China

Abstract

ObjectiveThe aim of this study was to examine the cervical cancer screening practices among women residing in Lingang New District of Shanghai. Moreover, the study aimed to delve into the characteristics of HPV infection and cervical lesions in older women (≥60 years old), seeking for more effective method for cervical cancer screening. MethodsThis is a cross-sectional study enrolled women who were referred to colposcopy and cervical histological examination due to abnormal cytology or HPV tests from Shanghai Sixth People's Hospital between January 2018 and December 2022. ResultsA total of 1,931 women (mean age: 41.8 ± 12.5, range: 18–88 years old) were enrolled, 119 individuals aged ≥ 60 and 1732 aged <60. The infection rates of HPV52, 33, 35, 56, 26 and 81 were significantly higher in the elderly group. Multiple HPV infection rates were also higher in this group and were associated with cervical lesions. The probability of LSIL, HSIL and Ca in women over 60 years old was significantly higher compared to women under 60. The top three HPV genotypes in elderly women with CIN2+ were HPV16, 52, and 58. The Yoden index was higher for extended typing for HPV 31/33/45/52/58(0.41) compared to cytology(0.29), high risk HPV without specific typing(0.07), cotest(cytology and high risk HPV, 0.06 or 0.30), or the current shunt strategy(0.07). ConclusionsElderly women still need to continue cervical cancer screening, and extended typing test for HPV16/18/31/33/45/52/58 is a more effective method for this age group.
