PURPOSE: Breast cancer (BC) is the most common cancer among Egyptian females. No current national cancer database is available in Egypt to provide reliable data on the specific clinicopathologic features of BC in this population. Herein, we investigated the clinical profile of BC among Egyptian women. METHODS: A systematic review of studies on BC published from inception until December 2021 was performed. We explored pooled estimated proportions of different stages of BC at presentation in Egypt and other clinicopathologic features including age, menopausal status, tumor (T) and lymph node (N) stages, and biological subtypes. Data analysis was performed using meta package (R). RESULTS: Twenty-six studies were eligible for our systematic review and meta-analysis, including 31,172 BC cases. In 12 studies, including 15,067 patients with BC, the estimated mean age was 50.46 years (95% CI, 48.7 to 52.1; I, 99%), with a pooled proportion of premenopausal/perimenopausal women of 57% (95% CI, 50 to 63; I, 98%). Among 9,738 patients with BC, pooled proportions of stage I, II, III, and IV were 6% (95% CI, 4 to 8; I, 90%), 37% (95% CI, 31 to 43; I, 93%), 45% (95% CI, 42 to 49; I, 78%), and 11% (95% CI, 9 to 15; I, 87%), respectively. The pooled proportions of patients with T3 and T4 tumors were 21% (95% CI, 14 to 31; I, 99%) and 8% (95% CI, 5 to 12; I, 96%), respectively, while those with positive lymph nodes were 70% (95% CI, 59 to 79; I, 99%). CONCLUSION: Dominance of advanced stage and young age at diagnosis represented the two main features of BC among Egyptian women. Our data may serve to guide the policymakers in Egypt as well as other countries with lower resources to prioritize the diagnostic and therapeutic needs in this context.
目的:乳腺癌(BC)是埃及女性中最常见的癌症。埃及目前没有国家癌症数据库来提供有关该人群中 BC 的具体临床病理特征的可靠数据。在此,我们研究了埃及女性中 BC 的临床特征。
方法:对截至 2021 年 12 月发表的关于 BC 的研究进行了系统回顾。我们探讨了埃及不同分期 BC 的汇总估计比例以及其他临床病理特征,包括年龄、绝经状态、肿瘤(T)和淋巴结(N)分期以及生物学亚型。使用 meta 包(R)进行数据分析。
结果:有 26 项研究符合我们的系统回顾和荟萃分析标准,包括 31,172 例 BC 病例。在 12 项包括 15,067 例 BC 患者的研究中,估计平均年龄为 50.46 岁(95%CI,48.7 至 52.1;I,99%),围绝经期/绝经前妇女的比例为 57%(95%CI,50 至 63;I,98%)。在 9,738 例 BC 患者中,I 期、II 期、III 期和 IV 期的比例分别为 6%(95%CI,4 至 8;I,90%)、37%(95%CI,31 至 43;I,93%)、45%(95%CI,42 至 49;I,78%)和 11%(95%CI,9 至 15;I,87%)。T3 和 T4 肿瘤患者的比例分别为 21%(95%CI,14 至 31;I,99%)和 8%(95%CI,5 至 12;I,96%),而淋巴结阳性患者的比例为 70%(95%CI,59 至 79;I,99%)。
结论:晚期为主的疾病分期和年轻的发病年龄是埃及女性中 BC 的两个主要特征。我们的数据可能有助于指导埃及以及其他资源较少的国家的决策者在这方面优先满足诊断和治疗需求。
