Radiotherapy is one of the most effective treatments for breast cancer. Three-dimensional conformal radiotherapy (3D-CRT) and intensitymodulated radiotherapy (IMRT) are two recently developed radiotherapy techniques. IMRT is believed to be more effective than 3D-CRT in target coverage, dose homogeneity and reducing toxicity to healthy organs. However, these advantages have not been demonstrated in the treatment of breast cancer. This meta-analysis was performed to compare IMRT and 3D-CRT in the treatment of breast cancer in terms of dose-volume histograms and outcomes, including survival and toxicity.
