1998-1999 Patterns of Care Study process survey of national practice patterns using breast-conserving surgery and radiotherapy in the management of Stage I-II breast cancer

Conclusion: The present results demonstrate a high level of compliance of the sampled radiation oncology practices with current breast conservation standards and continued improvement in many categories compared with prior patterns of care study surveys. The estimates in the current survey after whole breast RT will serve as a benchmark against newer trends in breast cancer RT, such as partial breast RT.
