BackgroundThe Instituto Angolano de Controlo do Cancer (IACC) Cancer Registry in Luanda, Angola is the most ancient and organized hospital-based cancer registry in Angola and provides data on cancer cases treated in several hospital facilities in Luanda.MethodsNewly-diagnosed cancer cases (2012–2016) of IACC were collected. A total of 6638 malignant neoplasms were recorded. After excluding duplicates, missing data and non-melanoma skin cancers cases, a final number of 5609 cancer cases was considered valid for analysis.ResultsFrom 5609 new cases, 2059 were males and 3550 females. Of all cases, 9.7% was in children below the age of 15 years. Most of the cases were residents from the Luanda district. The five most common cancers for all periods were breast (21.4%), cervix (16.8%), prostate (7.1%), non-Hodgkin lymphoma (4.5%) and Kaposi sarcoma (4.3%). For men, 19.3% of the cancers were prostate, 7.5% Kaposi sarcoma and 7.5% non-Hodgkin lymphoma. Cancers of the breast and cervix together accounted 60% of all cancers in females. Comparison of our data onto the 5 most frequent tumours, by sex, according to GLOBOCAN 2018 estimations for Angola, highlights the potential deviation from reality that estimates may have and reinforces the urgent need to build a truly population-based cancer registry in Luanda.ConclusionTo accomplish that task, it is mandatory to implement a more rigorous quality control program at the hospital-based cancer registry at IACC and to optimize the network of health institutions that actively working on and contributing to the cancer registry, in Luanda.

安哥拉罗安达医院癌症登记处：Instituto Angolano de Controlo do Cancer (IACC) 癌症登记处

背景安哥拉罗安达的 Instituto Angolano de Controlo do Cancer (IACC) 癌症登记处是安哥拉最古老、最有组织的以医院为基础的癌症登记处，并提供在罗安达的几家医院设施中治疗的癌症病例数据。方法新诊断的癌症病例 (2012) –2016) 的 IACC 被收集。共记录恶性肿瘤6638例。排除重复、缺失数据和非黑色素瘤皮肤癌病例后，最终5609例癌症病例被认为是有效的分析。结果从5609例新病例中，男性2059例，女性3550例。在所有病例中，9.7% 发生在 15 岁以下的儿童中。大多数病例是来自罗安达区的居民。所有时期最常见的五种癌症是乳腺癌（21.4%）、宫颈癌（16.8%）、前列腺癌（7.1%）、非霍奇金淋巴瘤（4.5%）和卡波西肉瘤（4. 3%）。对于男性，19.3% 的癌症是前列腺癌，7.5% 的卡波西肉瘤和 7.5% 的非霍奇金淋巴瘤。乳腺癌和宫颈癌共占女性所有癌症的 60%。根据 GLOBOCAN 2018 年对安哥拉的估计，将我们的数据与按性别划分的 5 种最常见肿瘤进行比较，突出了估计可能存在的与现实的潜在偏差，并强调了在罗安达建立真正以人群为基础的癌症登记处的迫切需要。为了完成这项任务，必须在 IACC 的医院癌症登记处实施更严格的质量控制计划，并优化在罗安达积极开展癌症登记工作并为癌症登记做出贡献的卫生机构网络。乳腺癌和宫颈癌共占女性所有癌症的 60%。根据 GLOBOCAN 2018 年对安哥拉的估计，将我们的数据与 5 种最常见的肿瘤（按性别）进行比较，突出了估计可能与现实存在的潜在偏差，并强调了在罗安达建立真正以人群为基础的癌症登记处的迫切需要。为了完成这项任务，必须在 IACC 的医院癌症登记处实施更严格的质量控制计划，并优化在罗安达积极开展癌症登记工作并为癌症登记做出贡献的卫生机构网络。乳腺癌和宫颈癌共占女性所有癌症的 60%。根据 GLOBOCAN 2018 年对安哥拉的估计，将我们的数据与按性别划分的 5 种最常见肿瘤进行比较，突出了估计可能存在的与现实的潜在偏差，并强调了在罗安达建立真正以人群为基础的癌症登记处的迫切需要。完成这项任务，必须在 IACC 的医院癌症登记处实施更严格的质量控制计划，并优化在罗安达积极开展癌症登记工作并为癌症登记作出贡献的卫生机构网络。
