Influence of Breast Reconstruction Type and Placement on Radiation Therapy Outcomes: Clinical Insights and Implications

Highlight

• Prepectoral and subpectoral breast reconstructions increase mean heart radiation dose compared with nonreconstruction.

• Subpectoral placement is associated with reduced ipsilateral lung dose during radiation therapy.

• Prepectoral reconstruction more frequently results in internal mammary node omission during radiation planning.

• Device type (immediate implant versus tissue expander) does not significantly affect radiation dose metrics or treatment timing.
