BMC Health Serv Res 2024; 24:102. [PMID: 38238704 PMCID: PMC10797973 DOI: 10.1186/s12913-023-10327-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 11/14/2023] [Indexed: 01/22/2024] Open
Abstract
BACKGROUND The burden of cancer can be altered by screening. The field of cancer screening is constantly evolving; from the initiation of program for new cancer types as well as exploring innovative screening strategies (e.g. new screening tests). The aim of this study was to perform a landscape analysis of existing cancer screening programs in South-East Asia and the Western Pacific. 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.

Mohammadi M, Salehzadeh A, Talesh Sasani S, Tarang A. rs6426881 in the 3'-UTR of PBX1 is involved in breast and gastric cancers via altering the binding potential of miR-522-3p. Mol Biol Rep 2021; 48:7405-7414. [PMID: 34655407 DOI: 10.1007/s11033-021-06756-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Accepted: 09/15/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Breast and gastric cancers are the most important diseases that lead to cancer death and social healthcare challenge. Overexpression of PBX1, a proto-oncogene, is correlated with the progression and metastasis of various cancers. For the first time, in this study the researchers evaluated the relationship between rs6426881, affecting miR-522-3p binding to the PBX1, with breast and gastric cancers. METHODS AND RESULTS The Microarray analysis was performed for finding the relative expression level of PBX1 and hsa-miR-522-3p, based on high throughput experiments. The GSE54397, GSE112369, GSE10810, GSE241585.ER, GSE24185.PR, GSE68373, and GSE38167 datasets were analyzed. A case-control study was carried out in 123 Iranian suffering from breast cancer and 132 participants as control samples as well as 130 people suffering from gastric cancer and 54 people as control group members. SNP rs6426881 in the 3'-UTR of PBX1 was genotyped by the High-Resolution Melting (HRM) method. Association analysis revealed that rs6426881 is correlated with Estrogen and Progesterone receptors, grade, and stage of breast cancer. Furthermore, a significant relationship was observed between the genotypes and blood groups in gastric cancer, while the distribution of alleles was significantly related to smoking, status of the primary tumor, and metastasis (Chi-Square P < 0.05). Finally, Bioinformatics analyses suggested that rs6426881 contains binding sites for miR-522-3p in the 3'-UTR of PBX1 transcript. The finding suggested that TT genotype is associated with poor prognosis in breast and gastric cancer. CONCLUSIONS The rs6426881 T allele at PBX1 3'-UT is significantly related to breast and gastric cancers by altering the regulatory affinity of miR-522-3p to PBX1 3'-UTR and may be suggested as a novel prognostic biomarker for the diseases.

Abstract
Aim: The aim is to study ANXA2 biomarkers for early diagnosis of cervical cancer. Materials & methods: The study used bioinformatics analysis and experimental verification of ANXA2 expression in cervical cancer. Results: ANXA2 expression was higher in cancer tissues than in non-cancer tissues (p = 0.002). ANXA2 was expressed in cell membranes of non-cancer tissues, whereas in cancer tissues it was expressed in both the cell membranes and the cytoplasm. Moreover, ANXA2 expression was more pronounced in squamous cell carcinomas. ANXA2 expression decreased overall survival of patients, and the data suggested that protein expression was associated with invasion and migration of tumors. Conclusion: ANXA2 has high specificity and sensitivity as a detection marker for cervical cancer and can assist in the diagnosis of cervical cancer.

Mahumud RA, Keramat SA, Ormsby GM, Sultana M, Rawal LB, Alam K, Gow J, Renzaho AMN. Wealth-related inequalities of women's knowledge of cervical cancer screening and service utilisation in 18 resource-constrained countries: evidence from a pooled decomposition analysis. Int J Equity Health 2020; 19:42. [PMID: 32216799 PMCID: PMC7098106 DOI: 10.1186/s12939-020-01159-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 03/09/2020] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Resource-constrained countries (RCCs) have the highest burden of cervical cancer (CC) in the world. Nonetheless, although CC can be prevented through screening for precancerous lesions, only a small proportion of women utilise screening services in RCCs. The objective of this study was to examine the magnitude of inequalities of women's knowledge and utilisation of cervical cancer screening (CCS) services in RCCs. METHODS A total of 1,802,413 sample observations from 18 RCC's latest national-level Demographic and Health Surveys (2008 to 2017-18) were analysed to assess wealth-related inequalities in terms of women's knowledge and utilisation of CCS services. Regression-based decomposition analyses were applied in order to compute the contribution to the inequality disparities of the explanatory variables for women's knowledge and utilisation of CCS services. RESULTS Overall, approximately 37% of women had knowledge regarding CCS services, of which, 25% belonged to the poorest quintile and approximately 49% from the richest. Twenty-nine percent of women utilised CCS services, ranging from 11% in Tajikistan, 15% in Cote d'Ivoire, 17% in Tanzania, 19% in Zimbabwe and 20% in Kenya to 96% in Colombia. Decomposition analyses determined that factors that reduced inequalities in women's knowledge of CCS services were male-headed households (- 2.24%; 95% CI: - 3.10%, - 1.59%; P < 0.01), currently experiencing amenorrhea (- 1.37%; 95% CI: - 2.37%, - 1.05%; P < 0.05), having no problems accessing medical assistance (- 10.00%; 95% CI: - 12.65%, - 4.89%; P < 0.05), being insured (- 6.94%; 95% CI: - 9.58%, - 4.29%; P < 0.01) and having an urban place of residence (- 9.76%; 95% CI: - 12.59%, - 5.69%; P < 0.01). Similarly, factors that diminished inequality in the utilisation of CCS services were being married (- 8.23%;95% CI: - 12.46%, - 5.80%; P < 0.01), being unemployed (- 14.16%; 95% CI: - 19.23%, - 8.47%; P < 0.01) and living in urban communities (- 9.76%; 95% CI: - 15.62%, - 5.80%; P < 0.01). CONCLUSIONS Women's knowledge and utilisation of CCS services in RCCs are unequally distributed. Significant inequalities were identified among socioeconomically deprived women in the majority of countries. There is an urgent need for culturally appropriate community-based awareness and access programs to improve the uptake of CCS services in RCCs.
