BACKGROUND

Cervical cancer remains to be the second leading cancer and cause of cancer-related deaths among Filipino women despite the use of the Papanicolaou screening. Latest research has shown that the human papillomavirus (HPV) is a necessary cause of cervical cancer. With major morbidity and high mortality rates associated with HPV infection and cervical cancer, several modes of primary and secondary forms of prevention have to be implemented. Among the primary modes of prevention is the administration of the preventive vaccine, which has consistently shown to decrease substantially HPV disease and cervical cancer rates in developed countries. In our country, before a successful vaccination, program is implemented, several sociocultural issues have to be addressed. Knowledge, attitude, and motivational factors are vital in determining acceptance of the vaccine. One relevant setting is exploring the willingness of mothers to get their female children vaccinated even before they become sexually active.

The aim of the study was to determine the association of the knowledge, attitude, and motivational factors of mothers on their willingness for their female children aged 9–13 years to undergo HPV vaccination at a tertiary government hospital.

This was a cross-sectional study that was carried out at a government institution.

The population consisted of 352 mothers with female children aged 9–13 years consulting the outpatient clinics at the department of obstetrics and gynecology at a tertiary government hospital.

A pretested and validated survey was given to 352 respondents. They were asked to answer a self-administered questionnaire that included sociodemographic, reproductive, sexual history variables, knowledge, and attitude, and motivational factors toward the disease and the associated vaccine.

Using the survey proportion estimation methods, the prevalence of women who were willing to enroll their daughters for HPV vaccination was 97.18% (n = 42, 95% confidence interval [CI]: 94.91 to 98.46%). It can be noted that only a third of the sample had high knowledge on the vaccine and its use 34.93% (n = 124, 95% CI: 30.25 to 39.92%). More women who reached college level (χ2: 5.67) and also those whose youngest child was between 11 and 13 years old (χ2: 8.82)-had higher knowledge scores than otherwise. Those who have an annual income of greater than or equal to P 60,000 (χ2: 16.55) and are non-Catholic (χ2: 18.77) – also appeared to have higher knowledge ratings on the questionnaire. Women who never to a few times a year attend church-related activities had higher knowledge scores compared to women who were more frequent goers (χ2: 16.33). For the attitude toward the vaccine, more mothers believed that getting the vaccine would not have an effect on a girl’s sexual activity and most agreed that they would not be viewed as bad parents. Most women also did not believe that religion would affect their willingness to vaccinate their children. There was an association in the degree of agreement between negative and positive attitudes from the Chi-square test performed (χ2: 7.44, P: 0.01). There were more agreeing responses from factors determining positive attitude and more disagreeing responses in the factors determining negative attitude. With regard to motivational factors, more women agreed that the cost was prohibitive and that they were more willing if only two doses would be required for their daughters. They were also not concerned about what other parents may think about getting the vaccine. Most answered that they were willing to follow their doctors’ recommendations and they have trust in vaccine manufacturers. Most women were also concerned that their daughters may get cervical cancer in the future. There was no difference in the proportion of agreeing responses between positive and negative motivating factors among the study participants (Z: 0.30, P: 0.79). This suggested that these factors could be important predictors of willingness to use vaccination on their children. Based on the crude odds ratios from the logistic regression, the likelihood of being willing to administer HPV vaccine to their children was almost twice as the knowledge score and scores on the positive attitude items increased, and was found to be statistically significant. At the same time, the odds of willingness increased by more than twice as the score on the negative attitude items decreased, and was also significant. There was no noted association for the other predictors of the association.

The role of knowledge and attitudes on the negative perceptions on the vaccine were important predictors of the willingness of mothers to have their female children vaccinated against HPV infection.

Cervical cancer is the third most prevalent cancer in women around the world. Recently in Korea, the incidence of cervical cancer has decreased, but in all stages of cervical intraepithelial neoplasia (CIN), CIN has shown a 91% increase from 1999 to 2008. Persistent human papillomavirus (HPV) infection has been found to be the main cause of cervical cancer. HPV types 16 and 18 have been found in 70% of cervical cancer patients around the world. Cervical cancer screening such as cytology has limitations in terms of sensitivity and specificity. A discussion about the need for the HPV test is becoming active in order to compensate for the limitation of cytology. After the role of HPV in cervical cancer was identified, the importance of HPV detection test as a screening was emphasized. Several tests have been developed and each test has its own advantages and disadvantages, and new test method to overcome the disadvantages is still being developed. Today's guidelines and tests are those you would choose from among the large number of cervical cancer screening guidelines and tests, based on the consideration that the selected guidelines and the test are effective.

OBJECTIVE: Ideal cancer screening program should be not only accurate but also cost-effective. However, in Korea, the two aspect of cervix cancer screening program was not yet evaluated. Thus we conducted this study to evaluate the cost-effectiveness and accuracy of various screening methods for detecting uterine cervical neoplasia. METHODS: We used various methods (conventional Pap smear, cervicography and HPV test) to detect cervical neoplasia on 255 women who visited the Seoul National University Hospital from Dec. 1996 to Jul. 1997 and analyzed the accuracy and cost-effectiveness of each method along with various combinations of methods using Bayesian theorem. The accuracy was judged by the final histopathologic diagnosis. RESULTS: Sensitivity (SE) and specificity (SP) of each method to detect cervical intraepithelial neoplasia (CIN) 1 or above were 83.0% and 69.4% in Pap smear, 53.7% and 85.2% in cervicography, and 57.8% and 80.6% in HPV test, respectively. The combination of Pap smear with cervicography or with HPV test for detecting CIN 1 or above had same SE and SP of 89.1% and 62.0% respectively. The combination of cervicography and HPV test had SE of 78.9% and SP of 70.4%. Three methods combination showed 93.9% SE and 54.6% SP. The estimated cost per method was highest in three methods combination (117,000 won) and lowest in Pap smear alone (12,000 won). The cost for detection of one case of cervical neoplasia was highest in combination of cervicography and HPV test (241,907 won) and lowest in Pap smear alone (25,385 won). CONCLUSION: The combinations of each method showed increased SE. These combinations, however, had low SP and high cost than individual method. Cervicography or HPV test alone should not be considered as an alternative to Pap smear for cervical cancer screening because its cost-effectiveness is not significantly better than that of Pap smear.

Multiple primary cancer means that more than two cancers are independently developed in one individual. The frequency of multiple primary neoplasm is increasing as a result of the lengthening average lifetime, progress in cancer screening technique, and improved cancer therapy. Gynecologic malignancies are especially prone to associated with primary neoplasms elsewhere. The frequency of multiple primary cancers was significantly higher in patients with uterine corpus cancer than in those suffering from cervical cancer. This case has different cell types of cancer in uterine cervix, thyroid and colon simultaneously. So, we report the case with a brief review of literatures.

Recently, a number of evidences that human papillomavirus (HPV) testing was efficient in cervical cancer screening were introduced. Moreover, successful trial outcome of preventive cancer vaccine opened new era of cervical cancer prevention. However, undoubtedly, applying new cancer screening and prevention strategy would bring on economical concern about increased medical expense. Therefore, appropriate cost-benefit analysis is very important before establishing new strategy as standard policy. In this article, we presented a few recent results about cost-benefit effectiveness by other group. And we also suggested what would be needed to perform successful.

OBJECTIVETo evaluate the effectiveness of FTA Elute® Cartridge (GE healthcare, Kent, UK) in combination with hybrid capture 2 (HC2) testing for cervical cancer screening.

METHODSFrom May to June 2012, 412 women aged 25 to 65 years in Jiangxi Tonggu were enrolled in the study. We used pathological outcome as the gold standard, and the accuracy of the FTA card in combination with HC2 testing was investigated from both physician- and self-sampling, respectively.

RESULTSPhysician sampling using the FTA card in combination with HC2 testing showed a comparable sensitivity (12/13) with the liquid based medium, but a higher specificity 69.5% (266/383) vs (77.8%, 298/383) (P < 0.001).When self sampling method was used, the sensitivity and specificity of using the FTA card in combination with HC2 testing with liquid based medium was 10/13 vs 8/13(P = 0.625) and (62.3%, 238/382) vs (75.7%, 289/382) (P < 0.001). The agreement of detection results for HC2 between FTA and liquid-based sampling medium was 86.1% (340/395) and 79.5% (314/395). For physician-collected samples used for HC2 testing to detect CIN2+, the accuracy of the FTA card was superior to that of the liquid-based medium (area under the receiver operating characteristic curve (AUC) = 0.898, 95%CI:0.838-0.958).

CONCLUSIONFTA Elute® cartridge in combination with HC2 testing is a promising method of specimen transport for cervical cancer screening programs with a good precision.With further optimization, it could become an effective method for cervical cancer screening in various economic levels of areas.

The rapid screening testing for cervical cancer prevention in low- and middle-income countries, careHPV assay, is developed by Cancer Hospital, Chinese Academy of Medical Sciences. The careHPV assay is the first HPV DNA detection technique worldwide, which is simple, fast, accurate, safe, and inexpensive. The testing technique was verified using clinical outcome as the endpoint, and its accuracy was similar to the current standard HPV detection technique and even higher than VIA. The popularization and application of careHPV could tremendously contribute to cervical cancer prevention in China as well as other developing countries. This would also reduce the disparity between developed and developing countries in cervical cancer prevention and help reduce the incidence and mortality of this disease.

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.
