The use of breast conservation surgery for early-stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes. In recent years, there has been renewed interest in incorporating a concurrent tumor bed boost to reduce the number of radiation treatments delivered. This focused review summarizes the literature surrounding the indications, outcomes, and treatment planning considerations for radiation tumor bed boost for early-stage breast cancer patients.
