HPV infection and cervical lesion cytotyping among medical staff in a class A hospital of Shanghai

ObjectiveTo study the relationship between cytology of cervical lesion and HPV in female medical workers.

MethodsFrom Fudan University Hospital of Obstetrics and Gynacology the results of cervical cytology screening in 1 093 female medical staff in 2015-2017 and results of HPV screening in 1 085 cases in 2017 were collected.SurePath liquid-based cell preparation was used for cytology and the segr-21 typing kit was used for HPV detection.The relationship between the pathological results of cervical colposcopy biopsy and HPV infection was studied by single factor and multiple factor regression analysis.

ResultsThe rate of HPV infection for subjects in the study was 10.0% (108/1 085), with increase in age, the infection rate showed an insignificant rising trend(χ²=4.43, P=0.11).High-risk HPV infection accounted for 95.37% (103/108), and the major high-risk HPV infections were HPV 52, HPV53, HPV58, and HPV16 in descending order.The 3-year cytological positive rates were 1.5%, 1.6% and 4.0%, respectively.Sixty-six of the HPV and/or cytological positive cases underwent colposcopy biopsy, and the proportion of cytology being positive, HPV positive, HPV16 positive, cytology negative in 2015 and 2016 was 41.1%, 19.1%, 60% and 29.7%, respectively.Multiple logistic regression showed that cytology was an independent risk factor, OR=7.87 (95%CI:1.85-33.54).

ConclusionThe rate of HPV infection in medical staff is lower than that in the general population, but the composition ratio of high-risk HPV infection is very high.It is recommended that women should undergo HPV test regularly from sexual life; early detection of high-risk HPV infection could prevent the occurrence of cervical cancer.The sensitivity and specificity of cervical cytology screening prove to be higher than those of HPV screening in people with low infection rate, and the cytology screening cycle should not exceed one year.
