Evaluation of bone scan as a screening work-up in primary and local-regional recurrence of breast cancer.
To evaluate the use of radionuclide bone scan in staging patients with primary and local-regional recurrence of breast cancer, we reviewed the results in 265 patients with primary breast cancer who had the scan either preoperatively or within 6 weeks of surgery, and in 39 patients presenting with their first local-regional recurrence. All patients were clinically staged according to the revised 1983 criteria of the American Joint Committee for Cancer Staging and End-Results Reporting. None of the 92 with stage I and four of 95 patients with stage II had a positive scan. ⋯ Seven converted in follow-up scans in 47 patients in the second year. We conclude that although bone scans have a low positive yield in stage I and II breast cancer, their use in the preoperative setting and in the follow-up of patients with axillary node involvement detects early converters. Bone scans are justified in stage IIIA and IIIB breast cancer and in patients being evaluated for local-regional recurrence.
