Abstract

INTRODUCTION: Breast cancer (BC) poses a significant global health challenge. In Sudan, the absence of a national cancer registry has resulted in an underestimation of BC incidence. BC is notably the most common cancer among Sudanese women, especially affecting those under 50, with many cases diagnosed at advanced stages. Angiogenesis, driven by vascular endothelial growth factor (VEGF), plays a critical role in the progression and recurrence of BC. This study examines the relationship between the VEGF (rs699947) gene polymorphism and BC among Sudanese women in Khartoum State in 2022. : A case-control study was conducted with 30 BC patients, and tissue samples were collected for molecular analysis. DNA was extracted and genotyped for the VEGF (rs699947) polymorphism using allele-specific PCR. RESULTS: No statistically significant association was found between the VEGF-2578 C > A polymorphism and BC risk in our study population. Although the A allele was more prevalent in tumor tissues compared to normal tissues, with no significant correlation with tumor stage or grade. The study revealed that BC in Sudanese women often presents at younger ages and is predominantly invasive ductal carcinoma, with stage II being the most common. CONCLUSION: These findings emphasize the necessity for continued research to explore additional genetic factors and improve our understanding of BC and associated risks. Advancing early detection and prevention methods is vital, particularly for underrepresented populations. However, the small sample size in this study may limit the statistical power to detect significant associations, and thus, findings should be interpreted with caution.

摘要

引言:乳腺癌是一项重大的全球健康挑战。在苏丹,由于缺乏国家癌症登记系统,乳腺癌发病率被低估。乳腺癌是苏丹女性中最常见的癌症,尤其影响50岁以下的女性,许多病例在晚期才被诊断出来。由血管内皮生长因子(VEGF)驱动的血管生成在乳腺癌的进展和复发中起着关键作用。本研究调查了2022年喀土穆州苏丹女性中VEGF(rs699947)基因多态性与乳腺癌之间的关系。进行了一项病例对照研究,选取了30例乳腺癌患者,并采集组织样本进行分子分析。提取DNA,并使用等位基因特异性PCR对VEGF(rs699947)多态性进行基因分型。 结果:在我们的研究人群中,未发现VEGF - 2578 C>A多态性与乳腺癌风险之间存在统计学显著关联。尽管与正常组织相比,A等位基因在肿瘤组织中更为普遍,但与肿瘤分期或分级无显著相关性。研究表明,苏丹女性的乳腺癌通常发病年龄较轻,主要为浸润性导管癌,II期最为常见。 结论:这些发现强调了持续研究以探索其他遗传因素并增进我们对乳腺癌及其相关风险理解的必要性。推进早期检测和预防方法至关重要,特别是对于代表性不足的人群。然而,本研究样本量较小可能会限制检测显著关联的统计效力,因此,对研究结果的解释应谨慎。
