Prior to 2019, there is a single cancer center treating cancer with 2-D Cobalt-60 radiotherapy. In 2023, the first patients were treated with modern radiotherapy techniques (3D-CRT, IMRT, VMAT) on linear accelerators. In previous work, we described the patterns for Cobalt-60 radiotherapy treatment in Ethiopia. 1–4 Due to limited radiation capacity, waiting times were long, median 150 days, for curative treatment due to the fact that symptomatic palliative radiotherapy was prioritized due to lack of capacity. Up to 3% patients had grade 3-4 toxicity, however toxicity was not routinely assessed. Little is known about the experience with modern radiotherapy techniques. Currently there are 4 regions in Ethiopia with modern radiotherapy. The purpose of this study is to describe the first patterns of linear accelerator radiotherapy and toxicity for cancer care in Ethiopia, from the Harari region in Eastern Ethiopia.
