“…In this study the age incidence of cancer was relatively early and high in comparison with other study which has been done on 286 patients in Iran; they found the incidence of cancer was higher in older age women age (Account et al, 2002) and other study from Canada (Nguyen et al, 2014).…”

Article InfoThis was a prospective clinical and pathological study included 24 Iraqi women patients complaining of breast lump managed in Alsader teaching hospital in Najaf. It is aimed to evaluate the benefit of fine needle aspiration (F.N.A.C.) cytology in comparison to histopathology examination in diagnosis of breast lump. Out of the 48 cases of breast lump to which F.N.A.C. was applied, the material aspirated by fine needle was found to be of benign cytology in 37 cases and malignant cells were diagnosed in 11 cases. The final histopathological examination of these 48 cases showed 34 cases benign and 14 were malignant. We have no false positive result in this study, specificity rate was (100%) and 2 false negative result giving sensitivity rate of (78.6%). Conclusion: Fine needle aspiration was highly specific and good sensitive compared to histopathology and can assist the diagnosis of breast lumps.

“…Later diagnosis was also predominant in another study where 64.2% of 4715 new breast cancer cases diagnosed in five provinces were found at Stage III or stage IV [29]. Two further papers, including one retrospective study on stages of diagnosis across five hospitals in 2009, found that 49.5% of the women were diagnosed with Stage III or IV breast cancer [15], while 67.7% in the second study were diagnosed at Stage II [30]. …”

Background: Breast cancer incidence has been increasing consistently in Vietnam. Thus far, there have been no analytical reviews of research produced within this area. Objectives: We sought to analyse the nature andextent of empirical studies about breast cancer in Vietnam, identifying areas for future research and systemsstrengthening. Methods: We undertook a scoping study using a five-stage framework to review published and grey literature in English and Vietnamese on breast cancer detection, diagnosis and treatment. We focused specifically on research discussing the health system and service provision. Results: Our results show that breast cancer screening is limited, with no permanent or integrated national screening activities. There is a lack of information on screening processes and on the integration of screening services with other areas of the health system. Treatment is largely centralised, and across all services there is a lack of evaluation and data collection that would be informative for recommendations seeking to improve accessibility and quality of breast cancer services. Conclusions: This paper is the first scoping review of breast cancer services in Vietnam. It outlines areas for future focus for policy makers and researchers with the objective of strengthening service provision to women with breast cancer across the country while also providing a methodological example for how to conduct a collaborative scoping review.

“…Reviewing process was held to select 10 studies related to the duration of oral contraceptive application with breast cancer risk in Southeast Asian women with a total 28,776 samples patients (Table 1) [13,[16][17][18][19][20][21][22][23][24].…”

“…Subgroup analysis for oral contraceptive use and breast cancer risk in Southeast Asia (Table 2). Ten studies assessing oral contraceptive application and breast cancer risk, seven were case-control studies [13,[16][17][18]21,22] with Pooled Odds Ratio (POR) 1.52 (1.06-2.18), heterogeneity test in these studies (P heterogeneity = <0.001; I 2 = 90%) resulted in various heterogeneous research on breast cancer risk, and three were cohort studies [19,20] with POR 1.34 (0.98-1.84), heterogeneity test in these studies (P heterogeneity = 0.28; I 2 = 21%) resulted in a variety of homogeneous research on the breast cancer risk.…”

“…Meanwhile, the proportion of oral contraceptive users in Southeast Asia is 12.8% [12]. Oral contraceptive users by country in Southeast Asia revealed that Thailand as the highest users (35%), followed by Indonesia (13.6%) and Vietnam (8.6%) [11,13]. Therefore, oral contraceptive application in Southeast Asia is relatively high yet the correlation with breast cancer risk is still under study.…”

Background: Breast cancer associated with variety of hormonal inter-ethnic and reproductive factors. Duration of oral contraceptives use with breast cancer risk is not well understood in Southeast Asian women. Methods: A comprehensive literature search of published articles from January 2001 to June 2019 (PubMed, ProQuest, and EBSCO online article databases) and meta-analysis were performed to link the duration of oral contraceptive application with risk of breast cancer among women in Southeast Asia. We identified the reference category, being ≤5 years' duration and >5 years' duration of oral contraceptive application. We use the Fixed and random-effect models to rely pooled odds ratios (OR). Egger's and Begg's test used for publication bias was presented with funnel plots. All analyzed data in Review Manager 5.3 (RevMan 5.3) and Stata version 14.2. Results: A total of 385 studies were reviewed and 10 studies involving a total of 28,776 women were included in a meta-analysis. This study found a slight increase in breast cancer risk in Southeast Asian women with oral contraceptives application ≤5 years with OR = 1.21 (95% CI 0.96-1.52, p>0.05). A higher risk of breast cancer was found in women with oral contraceptive application >5 years with OR = 2.66 (95% CI 1.79-3.94, p<0.00001). Publication bias and heterogeneity were not found particularly in a group of Southeast Asian women with oral contraceptive application for more than 5 years. Conclusion: Oral contraceptives use more than 5 years are at a higher risk in breast cancer among women in Southeast Asia. Although other reproductive factors including age at first childbirth, menarche, menopause, and lactation might influence the risk of breast cancer. Keywords: breast cancer, five years, oral contraceptive, Southeast Asia
