METHODS: An online questionnaire was circulated to different countries/cities in Asia-Oceania. The primary objective was to evaluate the coverage of HPV vaccination and cervical screening programs. The secondary objectives were to study the structures of these programs. Five case scenarios were set to understand how the respondents manage the abnormal screening results.
RESULTS: Fourteen respondents from 10 countries/cities had participated. Cervical cancer ranked the first in Myanmar and Nepal. About 10%-15% did not have national vaccination or screening program. The estimated coverage rate for vaccination and screening varied from less than 1% to 70%, which the coverage ran in parallel with the incidence and mortality rates of cervical cancer. All regions approved HPV vaccines, although only four provided free or subsidized programs for nonavalent vaccine. Cervical cytology remained the most common screening tool, and 20%-30% relied heavily on visual inspection using acetic acid. The screening age groups varied in different regions. From the case scenarios, it was noted that some respondents tended to offer more frequent screening tests or colposcopy than recommended by international guidelines.
CONCLUSION: This study revealed discrepancy in the practice of cervical cancer prevention in Asia-Oceania especially access to HPV vaccines. There is an urgent need for a global collaboration to eliminate cervical cancer by public education, reforming services, and medical training.
METHODS: The study was divided into two phases: (I) Marker discovery by miRNA microarray using paired cancer tissues (n = 30) and blood samples (CRC, n = 42; control, n = 18). (II) Marker validation by stem-loop reverse transcription real time PCR using an independent set of paired cancer tissues (n = 30) and blood samples (CRC, n = 70; control, n = 32). Correlation analysis was determined by Pearson's test. Logistic regression and receiver operating characteristics curve analyses were applied to obtain diagnostic utility of the miRNAs.
RESULTS: Seven miRNAs (miR-150, miR-193a-3p, miR-23a, miR-23b, miR-338-5p, miR-342-3p and miR-483-3p) have been found to be differentially expressed in both tissue and blood samples. Significant positive correlations were observed in the tissue and blood levels of miR-193a-3p, miR-23a and miR-338-5p. Moreover, increased expressions of these miRNAs were detected in the more advanced stages. MiR-193a-3p, miR-23a and miR-338-5p were demonstrated as a classifier for CRC detection, yielding a receiver operating characteristic curve area of 0.887 (80.0% sensitivity, 84.4% specificity and 83.3% accuracy).
CONCLUSION: Dysregulations in circulating blood miRNAs are reflective of those in colorectal tissues. The triple miRNA classifier of miR-193a-3p, miR-23a and miR-338-5p appears to be a potential blood biomarker for early detection of CRC.
METHODS: All 4930 women diagnosed with breast cancer in University Malaya Medical Center, Malaysia from 1993 to 2011 were included. Factors associated with very early presentation (stage I) at diagnosis were identified. Tumour characteristics, management patterns, and survival of very early breast cancer were described, and where appropriate, compared with other settings.
RESULTS: Proportion of women presenting with stage I breast cancer significantly increased from 15.2% to 25.2% over two decades. Factors associated with very early presentation were Chinese ethnicity, positive family history of breast cancer, and recent period of diagnosis. Within stage I breast cancers, median tumour size at presentation was 1.5 cm. A majority of stage I breast cancer patients received mastectomy, which was associated with older age, Chinese ethnicity, postmenopausal status, and larger tumours. Chemotherapy was administered in 36% of patients. Five-year age-adjusted relative survival for women with stage I breast cancer was 99.1% (95% CI: 97.6-99.6%).
CONCLUSIONS: The proportion of women presenting with very early breast cancer in this setting without organised screening is increasing. These women seem to survive just as well as their counterparts from affluent settings.
METHODS: We conducted an overview of cancer screening in the region with the goal of summarizing current designs of cancer screening programs. First, a selective narrative literature review was used as an exploration to identify countries with organized screening programs. Second, representatives of each country with an organized program were approached and asked to provide relevant information on the organizations of their national or regional cancer screening program.
RESULTS: There was wide variation in the screening strategies offered in the considered region with only eight programs identified as having an organized design. The majority of these programs did not meet all the essential criteria for being organized screening. The greatest variation was observed in the starting and stopping ages.
CONCLUSIONS: Essential criteria of organized screening are missed. Improving organization is crucial to ensure that the beneficial effects of screening are achieved in the long-term. It is strongly recommended to consider a regional cancer screening network.
METHODS: A cross sectional study was performed in three randomly selected centres that organised pre-marital courses. All Malay Muslim women participants aged 18 to 40 years old were recruited while non-Malaysian, illiterate, and had hysterectomy were excluded. Validated self-administered questionnaires used were European Health Literacy Questionnaire (HLS-EU-Q16 Malay) and Knowledge and attitude towards Cervical Cancer and Pap Smear Questionnaire. The mean percentage score (mean± SD) was calculated, with higher scores showed better outcomes. Multiple linear regression was used to measure the relationship of independent variables with attitude towards Pap smear.
RESULTS: A total of 417 participants were recruited with a mean age of 24.9 ± 3.56 years old. Prevalence of awareness of cervical cancer was 91.6% (n=382, 95% CI: 89.0%, 94.2%) and mean percentage score was 74.7%±7.6. Prevalence of awareness of Pap smear was 59.0% (n=246, 95% CI: 54.2%, 63.8%) and mean percentage score was 80.2% ± 6.5. The health literacy mean score was 13.3±3.6, with minimum score 0 and maximum score 16. The mean percentage score of attitudes towards Pap smear was 64.8%±9.3. Multiple linear regression analysis demonstrated significant relationship between health literacy (p=0.047) and knowledge of Pap smear (p<0.001) with attitude towards Pap smear.
CONCLUSION: A higher health literacy with high knowledge of Pap smear improves the attitude towards Pap smear. Pre-marital course is an opportunistic platform to disseminate information to improve health literacy and knowledge of cervical cancer and Pap smear screening.
Methods: Online databases (PubMed/MEDLINE/PubMed Central, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and Google Scholar) were searched for all published eligible research articles in the past 12 years (as of January 2005-2017). A total of 17 research articles were included. The interventions were classified as 'individual level', 'community level' and 'cultural sensitive educations' which contains various interventions in their content as compared with usual care. A quality coding system was assessed using Cochrane checklists and rated by each researcher independently and the average score was given accordingly. This study was registered in PROSPERO 2017: CRD42017060405.
Results: The review dovetailed 17 studies. Ten studies (58.82%) were conducted in the United States, three in Iran (17.65%) and one each in Malaysia, China, Cameroon and Nigeria (23.53%). Almost all levels of the interventions boosted the screening uptake and the Pap test. However, the individual level health education interventions were prioritized in many of the studies.
Conclusion: The review indicated that health education interventions have immense contributions in boosting the screening uptake. However, the effectiveness varies with study setting, populations and the way of delivery. Therefore, the limited quality of the studies indicated that further research is required to develop a simple and effective intervention to boost cervical cancer screening uptake.
