Cervical disease is a common and frequent disease in women. Among various malignant tumors in women, the incidence of cervical cancer ranks second after breast cancer, and the trend of young patients has increased significantly in recent years. 80% of patients have already developed into invasive cancer (i.e., can spread and affect life expectancy) when they are diagnosed, and it takes about 10 years to develop from cervical precancerous lesions into cervical cancer, so the Therefore, early diagnosis and treatment of cervical precancerous lesions is an important measure to reduce the incidence of cervical cancer. Very early cervical cancer may be asymptomatic or may only have watery vaginal discharge or bleeding after sexual intercourse, which are often ignored by patients. However, because the cervix is easily exposed, an accurate diagnosis can usually be made through cervical cytology and cervical biopsy. In the U.S., all women who start having sex are required to undergo cervical cancer cytology once a year. tCT, short for liquid-based thin-layer cytology, uses a liquid-based thin-layer cytology detection system to detect cervical cells and perform cytological classification and diagnosis. it is the most advanced cervical cancer cytology screening technology internationally, which significantly improves specimen satisfaction and Cervical abnormal cell detection rate. The incidence of cervical cancer is decreasing in developed countries with the widespread implementation of screening, but in developing countries with large populations, the incidence of cervical cancer is still a concern due to insufficient screening, with 270,000 deaths from cervical cancer each year. After effective surgery and simultaneous radiotherapy treatment, the cure rate for patients with early-stage cervical cancer (stages I and II) is up to 80%, but only 60% for stage III patients. It is promising that immunotherapy against human papillomavirus (HPV) can prevent persistent infection with high-risk HPV types and is expected to prevent certain specific HPV-caused cervical cancers.
