赞比亚胃癌的确切患病率尚不清楚。本研究旨在确定赞比亚最大医院就诊的胃癌病例所占比例，这些病例的记录已包含在赞比亚国家癌症登记处（ZNCR）中。我们回顾了2015年1月至2017年12月期间来自赞比亚大学教学医院、肿瘤疾病医院和ZNCR的胃癌记录。使用Stata 15软件进行了统计分析。我们回顾了94份患者记录（其中42位为女性），平均年龄为59岁（标准差14.9）。在组织学上，大多数病例为腺癌（84%）。在回顾的记录中，只有39/94（42%）的数据被包含在ZNCR中。从内镜诊断到组织病理学确认的中位时间为11天（四分位数范围：7-20天）。从组织学确认到肿瘤疾病医院进行治疗的中位时间为8天（IQR 2-19）。胃癌患者的总体中位生存时间为290天（95% CI，112-1225天）。ZNCR报告的胃癌数据低估了实际的疾病负担，应加强赞比亚胃癌数据收集策略。© 2023 Shumba S et al.

The exact prevalence of gastric cancer in Zambia is unknown. The aim of this study was to determine the proportion of gastric cancer cases seen at the largest hospital in Zambia, whose records were included in the Zambia National Cancer Registry (ZNCR).We reviewed gastric cancer records between January 2015 and December 2017 from the University Teaching Hospital, Cancer Diseases Hospital and ZNCR. Statistical analysis was done using Stata version 15.We reviewed 94 patient records (42 were females) with a mean age of 59 years (standard deviation, 14.9). Histologically, the majority of the cases were adenocarcinoma (84%). Of the reviewed records, only 39/94 (42%) had their data included in the ZNCR. Median time to from endoscopic diagnosis to histopathological confirmation was 11 days (inter-quartile range; 7-20). Median time from histological confirmation to the Cancer Diseases Hospital for therapy was 8 days (IQR 2-19). Overall median survival time for gastric cancer patients was 290 days (CI 95%, 112 - 1225).Data on gastric cancer reported in the ZNCR are an underestimate of the true disease burden and there is need to strengthen data collection strategies for gastric cancer in Zambia.© 2023 Shumba S et al.
