Nailing the Clavicular Head: Assuring Adequate Coverage of the Medial/Inferior Aspect of the Supraclavicular Space in Patients Receiving Regional Nodal Radiation Therapy for Breast Cancer
Practical Radiation Oncology(2023)
Abstract
Radiation therapy (RT) fields used for patients with breast cancer traditionally targeted anatomic regions and had borders that were largely based on palpable (or radiologically visible) anatomic landmarks. The transition to computed tomography (CT)–based 3-dimensional (3D) planning necessitated the definition of internal anatomic targets to guide planning. Risk-Adapted Target Delineation for Breast Cancer: Controversies and ConsiderationsPractical Radiation OncologyVol. 13Issue 2PreviewThe advent of computed tomography–based planning coupled with modern tools for target delineation and hypofractionated treatment schedules has increased efficiency and throughput for patients with breast cancer. While the benefit of adjuvant radiation therapy (RT) in reducing locoregional recurrences is established, disentangling local versus regional recurrence risks with modern treatment protocols has become an area of active research to de-escalate treatment. Delineation guidelines for nodal regions either attempt to replicate results of conventional RT techniques by translating bony landmarks to clinical target volumes or use landmarks based on the fact that lymphatic channels run along the vasculature.
