The anticancer screening results demonstrated that compounds N9, N18 (IC50 = 5.85, 4.53 µM) were the most potent compounds against cancer cell line (HCT116) even more than 5-FU, the standard drug (IC50 = 9.99 µM).
METHODS: The findings for a few outcome indicators, ranging from the iFOBT uptake to the CRC and polyp detection rates, were generated from the data contributed by 583 public health clinics between 2014 and 2018. The trends in their changes were also evaluated.
RESULTS: The iFOBT uptake constantly increased over the years (p < 0.001), totaling 2.29 % (n = 127,957) as at 2018. Nearly 10 % (n = 11,872) of the individuals screened had a positive test result. Of those who underwent colonoscopy (n = 6,491), 4.04 % (n = 262) and 13.93 % (n = 904) were found to have CRC and polyps, respectively.
CONCLUSION: An uptrend in the CRC screening uptake was witnessed following the introduction of the iFOBT in public health clinics.
DISCUSSION: This paper presents comprehensive report on breast carcinoma disease and its modalities available for detection and diagnosis, as it delves into the screening and detection modalities with special focus placed on the non-invasive techniques and its recent advancement work done, as well as a proposal on a novel method for the application of early breast carcinoma detection.
CONCLUSION: This paper aims to serve as a foundation guidance for the reader to attain bird's eye understanding on breast carcinoma disease and its current non-invasive modalities.
METHODS: This paper reviews devices invented for different cervical cancer screening methods, which are Pap smear test, visual inspection with acetic acid (VIA) or Lugol's iodine (VILI), and HPV (human papillomavirus)-DNA (deoxyribonucleic acid) self-test in terms of functionality, performance in solving the limitations of screening procedure and additionally where applicable, the cervical cell collection efficacy and abnormality detection accuracy. The devices are either available in the market, published in research articles or published in international patent databases.
RESULT: The reviewed devices either simplified the screening procedure to improve the clinical efficiency and accuracy in screening, reduced the pain and discomfort experienced by women during screening procedures, or achieved both outcomes.
CONCLUSION: Many devices have been invented to improve the screening procedures which may potentially improve the uptake in cervical screening tests and encourage the organization of screening campaigns to reduce cervical cancer incidence.
Case presentation: We present a case of 15-year-old boy from rural area, presented with chronic diarrhea and per rectal bleeding for 3 months. The diagnosis was determined by colonoscope which revealed a fungating mass identified at 10cm from anal verge. Histological examination confirmed diagnosis of signet ring cell adenocarcinoma. CT scan of the abdomen showed thickening involving the recto-sigmoid colon and rectal mass, without evidence of distant metastatic disease. The patient's carcinoembryonic antigen level was within the normal range. He underwent a colostomy and was subjected to neoadjuvant CCRT and surgery.
Discussion: This CASE highlights the importance and challenges in achieving early diagnosis and surgical intervention of signet-ring cell carcinoma in adolescents, as most cases are detected at an advanced stage coupled with the scarcity of information on these rarer subtypes which leads to a poor prognosis.
Conclusion: In managing Signet cell carcinoma of the colorectal, physician have to know that it has a poor prognosis in patients of any age. However, in young teenagers delayed diagnosis and treatment option are narrowed to palliative management. Genetic profiling of family members and similar environment population may be a key to early detection.
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.
OBJECTIVE: This study aimed to review and analyse literature related to the detection and classification of acute leukaemia. The factors that were considered to improve understanding on the field's various contextual aspects in published studies and characteristics were motivation, open challenges that confronted researchers and recommendations presented to researchers to enhance this vital research area.
METHODS: We systematically searched all articles about the classification and detection of acute leukaemia, as well as their evaluation and benchmarking, in three main databases: ScienceDirect, Web of Science and IEEE Xplore from 2007 to 2017. These indices were considered to be sufficiently extensive to encompass our field of literature.
RESULTS: Based on our inclusion and exclusion criteria, 89 articles were selected. Most studies (58/89) focused on the methods or algorithms of acute leukaemia classification, a number of papers (22/89) covered the developed systems for the detection or diagnosis of acute leukaemia and few papers (5/89) presented evaluation and comparative studies. The smallest portion (4/89) of articles comprised reviews and surveys.
DISCUSSION: Acute leukaemia diagnosis, which is a field requiring automated solutions, tools and methods, entails the ability to facilitate early detection or even prediction. Many studies have been performed on the automatic detection and classification of acute leukaemia and their subtypes to promote accurate diagnosis.
CONCLUSIONS: Research areas on medical-image classification vary, but they are all equally vital. We expect this systematic review to help emphasise current research opportunities and thus extend and create additional research fields.
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.
