title: Occult breast cancer in two community hospitals in New York State.
abstract: The histopathologic results of 360 consecutive preoperative needle localizations of nonpalpable breast lesions performed at two community hospitals in New York State were analyzed for comparison with national data. Seventy-eight (21.6%) samples were malignant lesions. Sixty of the 78 (76.4%) were infiltrative lesions, and 18 (23.6%) were in situ carcinomas. Overall, axillary lymph node metastases were noted in five (8.3%) samples. We conclude that needle localization permits detection of occult carcinoma at an early stage and that detection of occult carcinoma in patients seen in a community hospital corresponds well with published national data.
