Abstract:
Objective To analyze the screening data of cervical cancer in rural areas of Dalian from 2014 to 2019, to understand the screening effect of cervical cancer in rural areas of Dalian, and to evaluate the detection effect of different screening methods, so as to provide scientific suggestions for the prevention and treatment of cervical cancer.
Method The data were obtained from the data of the cervical cancer screening in rural areas of Dalian from 2014 to 2019 in the information reporting system of major public health services for women and children. The primary screening methods included cervical cytology tests(Pap smear, liquid-based cytology) and HPV test. The Chi-square test was used to compare the positive rate of primary screening, the detection rate of cervical cancer and precancerous lesions and the early diagnosis rate between different screening methods and years.
Result A total of 149,918 rural women aged 35-64 years old were screened for cervical cancer free of charge in 2014-2019. The number of women with positive screening results was 8,984, and the positive rate was 5.99%. 799 were diagnosed as precancerous lesions, and the detection rate was 532.96/10
5. 41 were diagnosed as invasive cervical cancer, and the detection rate was 27. 35/10
5. Among them,9 cases were diagnosed as early cervical cancer, and the early diagnosis rate was 96. 19%. The comparison of two different screening methods showed that the positive rate, the detection rate of low-grade squamous intraepithelial lesions, the detection rate of high-grade squamous intraepithelial lesions, and the detection rate of cervical precancerous lesions of HPV test were higher than those of cervical cytology(10.13%
vs 3. 04%, 713. 41/10
5 vs 609. 83/10
5, 675. 02/10
5 vs 424. 48/10
5, and 679. 82/10
5 vs 427. 91/10
5, respectively), and the differences between the two screening methods were statistically significant(
P< 0. 05).
Conclusion The effect of cervical cancer screening in rural areas of Dalian from 2014 to 2019 is obvious. Compared with cervical cytology test, cervical cancer screening strategy based on HPV test as the primary screening method can better detect cervical precancerous lesions and facilitate earlier follow-up management. Each district and county should make a scientific, efficient and feasible cervical cancer screening program strategy according to the local actual situation.
