Abstract

Context Biopsies provide histological diagnosis and as such may guide subsequent management of breast lumps. Regular audit of such biopsies are necessary to document epidemiological pattern of the histological diagnosis within a population. Objective To review the histological diagnoses of breast biopsies in two referral centres in the Niger Delta region of Nigeria. Methodology This is a descriptive analysis of retrospective data obtained from the Central Hospital Warri and the University of Benin Teaching Hospital, Benin City, all in the Niger-Delta region of Nigeria between 2005 and 2010. Results Data on 367 biopsies were analysed. Patients with benign diagnoses aged in range between 14 and 48 years and those with malignant conditions between 20 and 85 years. Fibroadenoma was the commonest histological diagnosis (36.0%) with a mean age at diagnosis of 22.9 5.5 years. Just one case of fibroadenoma was recorded beyond 36 years. years. Malignancies were seen in 29.4% of biopsies with Invasive ductal carcinoma being the dominant histological type, 89.8%. The mean age at diagnosis of breast cancer was 46.0 12.1 years. Incidence of malignant findings ranged from less than 1 in 10 biopsies below 30 years, 1 in 2 biopsies at the 31-35 years age range to nearly unit in those 56 years and above. Conclusion Fibroadenoma is the commonest breast biopsy finding in the referral centres in the Niger Delta. Breast cancer occurs commonly among premenopausal women. Key words: Breast, Biopsy, Fibroadenoma, Invasive ductal carcinoma.
尼日尔三角洲两家医院开放性乳房活检的审计
活组织检查提供组织学诊断,因此可以指导乳腺肿块的后续处理。定期审核这种活检是必要的,以记录人群中组织学诊断的流行病学模式。目的回顾尼日利亚尼日尔三角洲地区两个转诊中心乳腺活检的组织学诊断。这是对2005年至2010年期间从尼日利亚尼日尔三角洲地区的瓦里中心医院和贝宁市的贝宁大学教学医院获得的回顾性数据进行的描述性分析。结果对367例活检资料进行分析。良性诊断的患者年龄在14至48岁之间,恶性诊断的患者年龄在20至85岁之间。纤维腺瘤是最常见的组织学诊断(36.0%),平均诊断年龄为22.9 - 5.5岁。仅1例纤维腺瘤超过36岁。年。恶性肿瘤占29.4%,浸润性导管癌为主要组织学类型,占89.8%。乳腺癌诊断的平均年龄为46.0 - 12.1岁。恶性肿瘤的发生率从30岁以下的不到1 / 10,31-35岁的1 / 2到56岁及以上的近1 / 1不等。结论纤维腺瘤是尼日尔三角洲转诊中心最常见的乳腺活检发现。乳腺癌常见于绝经前妇女。关键词:乳腺,活检,纤维腺瘤,浸润性导管癌。
