[Effectiveness of mammary scintigraphy for determining the results of neoadjuvant polychemotherapy in breast cancer].

Analysis of mammoscintigraphy is presented to assess the effectiveness of neoadjuvant polychemotherapy for locally advanced breast cancer. In 90% of patients there is defined conformity of scintigraphy data on the effectiveness of performed polychemotherapy to the results of histologic examination of the postoperative material. The sensitivity of scintigraphy in assessing the effectiveness of neoadjuvant polychemoterapy was 83.3%, specificity--87.9%, accuracy--86.3%, predictive value of positive and negative results-78.9% and 90.1%, respectively. Mammoscintigraphy is an effective method to control the response of locally advanced breast cancer to neoadjuvant polychemotherapy.
