[Possibilities of various diagnostic methods in the assessment of the state of axillary lymph nodes in breast cancer].

The incidence of axillary lymph nodal metastases in breast cancer is proportional to the size of a focus: To is 25 +/- 25%, T1-33 +/- 17%, T2-55 +/- 7%, T3-65 +/- 11%, the choice of the optimum treatment regimen requires more accurate preoperative detection of metastatic lymph nodes. Ultrasound technique (its accuracy is 80%, sensitivity-88%) is of the most diagnostic value in the detection of metastatic lymph nodes. The absence of echographic signs supports the nonspecific nature of changes. Palpation is preferable in nonspecific axillary lymph nodal lesions. The status of axillary lymph nodes in breast cancer may be correctly assessed by comprehensive clinical and ultrasonic studies of the axillary area wherein, supplementing each other, each technique yield the maximum information.
