FIELD: medicine; mammology; oncology.
SUBSTANCE: invention can be used for intraoperative confirmation of diagnosis of breast cancer with metastasis in subclavian and/or axillary lymph nodes. Oxygen saturation of arterial blood hemoglobin in a breast tumor, a lymph node and a hand is examined intraoperatively. Oxygen index is determined as a ratio of oxygen saturation of arterial blood hemoglobin in a breast tumor to arterial blood hemoglobin saturation with oxygen, and ratio of arterial blood hemoglobin oxygen saturation in lymph node to oxygen saturation of arterial blood hemoglobin. If the oxygen index is 0.5, the diagnosis of breast cancer with metastasis in subclavian and/or axillary lymph nodes is confirmed.
EFFECT: method enables the intraoperative confirmation of a diagnosis of breast cancer with metastases to determine the scope of the operation by examining oxygen saturation of arterial blood hemoglobin in a breast tumor, in a lymph node and finger and calculating an oxygen index by these indices.
