OBJECTIVE: Although a great deal of knowledge accumulated with regard to the causes and epidemiologic features of cervical cancer, primary prevention has not been particularly effective to date. Most efforts with regards of control of cervical cancer have been directed toward secondary prevention with cytologic smears in a screening program. The purpose of this study was to know the cervical smear histories in the women with neoplasia of uterine cervix at present. MATERIALS AND METHOD: Between June, 1993 and October, 1996, seventy women with invasive cervical carcinoma and eighty-seven women with cervical intraepithelial neoplasia(CIN) were interviewed about cervical smear histories to assess the frequencies of past smear at the Soonchunhyang University Hospital. RESULTS: The results were follows: 1. The mean age of the women with invasive cervical cancer and CIN were 55+/-9 and 42+/-11, respectively. 2. Of the 70 cases of cervical cancer, 61%(43/70) has not been screened, compared with 43%(37/87) in cases of CIN. 3. The mean ages at first smear in the cases of previous smear were 42+/-6 of 27 cancers, 37+/-7 of 50 CINs. The gap between the age at the first smear and the age at diagnosis were about 6 years in cases of cervical cancers, about 5 years in cases of CIN. 4. The most common symptom in cervical cancers was vaginal bleeding or postcoital bleeding(57%). Although 13%(9/70) were discovered during screening without symptom in the women with cervical cancers, 58%(52/87) were diagnosed incidently during screening in CIN. 5. Pap smear numbers before diagnosis were strongly associated with age and stage. Among women diagnosed with invasive cancer under the age of 49, 75% had at least one cervical smear. But, all women with cervical cancer over age of 65 have not been screened. Unscreened rates of stage I, II, III, and IV were 34%, 78%, 85% and 83% respectively. 6. Among 38 cases who had undergone radiation therapy, 82%(31/38) had not been screen in contrast to 38%(12/32) in the women who had undergone radical surgery. 7. Among women with previous smears in the cervical cancer, 20%(14/70) have been screened within 1year. CONCLUSION: It is likely to diagnosis cervical cancer who had normal papanicolau smear in recent. So papanicolau smear is examined carefully and other adjunctive test is help to diagnosis cervical cancer exactly, for example cervicography, HPV testing.

OBJECTIVE: To estimate the significance of the Pap smear as a screening tool for cervical cancer. METHODS: A total of 79,840 Pap smear results performed at Pusan Paik Hospital over the 20 year period from 1979 to 1998 were collected and analyzed. RESULTS: The number of Pap smear cases increased markedly during this period, and the results as a whole were classified as consisting of 96.4% normal and benign cytology, 2.2% pre-cancerous cytology, and 1.4% cervical cancer. The relative frequency of cervical cancer decreased from 1.6% in 1979 to 0.7% in 1998. About 64% of the Pap smears were distributed within the age range of 30 to 49 years, and the rate of cervical cancer increased with age, age of marriage and experience of childbirth (p<0.01). The overall agreement of Pap smear results with histologic diagnosis by one histologic degree was 92.7%(1,128/1,217) with 73 overestimated cases and 16 underestimated cases of Pap smear compared to histologic diagnosis. CONCLUSION: This result implies that the Pap smear is an excellent screening tool for cervical cancer with respect to both its scale and validity. Periodic and active Pap smear testing would be helpful for the secondary prevention of cervical cancer.

OBJECTIVE: The aim of this study was to develop and validate a questionnaire used to assess the level of general knowledge about cervical cancer, its primary and secondary prevention, and to identify sources of information about the disease among schoolgirls and female students. METHODS: The questionnaire development process was divided into four phases: generation of issues; construction of a provisional questionnaire; testing of the provisional questionnaire for acceptability and relevance; field-testing, which aimed at ensuring reliability and validity of the questionnaire. Field-testing included 305 respondents of high school female Caucasian students, who filled out the final version of the questionnaire. RESULTS: After phase 1, a list of 65 issues concerning knowledge about cervical cancer and its prevention was generated. Of 305, 155 were schoolgirls (mean age+/-SD, 17.8+/-0.5) and 150 were female students (mean age+/-SD, 21.7+/-1.8). The Cronbach alpha coefficient for the whole questionnaire was 0.71 (range for specific questionnaire sections, 0.60 to 0.81). Test-retest reliability ranged from 0.89 to 0.94. CONCLUSION: The Cervical-Cancer-Knowledge-Prevention-64 has been successfully developed to measure the level of knowledge about cervical cancer. The results confirm the validity, reliability and applicability of the created questionnaire.

Cervical cancer is a complex disease caused by both genetic susceptibility and environmental factors. Inherited genomic variance, high-risk human papilloma virus (HPV) infection/integration, genome methylation and somatic mutation could all constitute one machine learning model, laying the ground for molecular classification and the precision medicine of cervical cancer. Therefore, for cervical screening, next generation sequencing (NGS)-based HPV DNA and other molecular tests as well as dynamic machine learning models would accurately predict patients with potential to develop the cancer, thereby reducing the burden of repeated screening. Meantime, genome-editing tools targeting HPV would emerge as the next generation gene therapy for HPV-related cervical lesions. In this article, we review the substantial progress on molecular mechanism of cervical cancer development and suggest the future for precise prevention and early treatment of cervical cancer.

Cervical cancer is the second most common malignant tumor in women worldwide.The burden of cervical cancer is particularly heavy in less developed countries as the malignancy brings huge pain to the patients and their family members and causes huge losses to social development and global health.However,cervical cancer is a preventable and curable disease.While screening and human papillomavirus vaccination in developed countries have remarkably lowered the incidence and mortality of cervical cancer,there is still a far way to go to achieve the prevention and treatment of this disease.The multidisciplinary prevention and control programs slightly differ in different countries due to diverse economic and health conditions.The general principle is to vaccinate the young females and to implement a comprehensive strategy including human papillomavirus vaccine vaccination,screening,early diagnosis,and early treatment in adults.

The world is entering a new era of accelerated elimination of cervical cancer, while the age-standardized incidence, and mortality of cervical cancer in China are rising rapidly. This article summarizes and describes the current situation and trends of the burden of cervical cancer in China, reviews and analyzes the comprehensive prevention practice of cervical cancer, focusing on critical reasons for the increasing burden of cervical cancer, from the perspectives of sociology, behavior, and epidemiology in the population. Countermeasures are proposed to provide guidance and theoretical reference for the precise prevention of cervical cancer to eliminate cervical cancer.

Cervical cancer mainly caused by human papillomavirus (HPV) infection has become a public health issue, which seriously threatens women 's health. To prevent HPV infection, the currently used prophylactic vaccines mainly induce a humoral immune response in the host, thereby generating neutralizing antibodies. In contrast, the design goal of therapeutic HPV vaccines is to induce a cell-mediated immune response in the host, primarily driven by Th1 cells, aiming to clear existing viral infections and slow down or inhibit tumor progression. Currently, several therapeutic HPV vaccines based on different mechanisms and techniques have entered clinical trials. This review will summarize the progress of these clinical trials, providing reference for the research and development of therapeutic HPV vaccines.
