METHOD OF SURGICAL TREATMENT OF BREAST CANCER AT EARLY STAGES OF TUMOR PROCESS Russian patent published in 2019 - IPC A61B17/00 A61B6/03 A61K51/10 A61K49/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology, and can be used for treating breast cancer at early stages of tumor process. That is followed by intra-tumor introduction of radiopharmaceutical 99 mTc-technefite in dose of 7.5 to 15 MBq. After 60–120 minutes, the axillary, parasternal, supra- and subclavian lymph nodes are scintigraphically examined on the side of the breast tumor localization. A signal lymph node which accumulates a radiopharmaceutical is detected, then it is removed and an urgent histologic examination is performed. If there is no metastases in the signal lymph node, the breast tissue sector is excised together with the tumor, and if observing the tumor changes in the signaling lymph node, the breast tissue sector is excised together with the tumor and lymphadenectomy.

EFFECT: method provides surgical treatment of breast cancer at early stages of tumor process with individualization of lymphadenectomy volume, as well as minimization of irradiation of patient and reduced time of operation due to intraoperative examination of signaling lymph node.
