Conservative surgery and radiotherapy for stage I/II breast cancer using lung density correction: 10-year and 15-year results

Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast cancer-specific survival, and overall survival compared with other reported series of breast-conserving surgery and RT in early-stage disease. These results will serve as a benchmark against which newer radiation delivery strategies such as intensity-modulated RT and partial breast RT can be compared.
