Introduction: At present, despite the advent of innovative methods such as IMRT, which improves therapeutic performance while reducing toxicity, RC3D is still widely used, especially in developing countries. The objective of this work was to evaluate the urinary and digestive toxicities of RC3D on prostate cancers located at the Pointe à Pitre University Hospital in Guadeloupe in order to position this technique in the therapeutic arsenal. Materials and methods: We conducted a retrospective study of 29 patients with localized prostate cancer treated with RC3D. The endpoint was urinary and digestive toxicities.
