METHOD FOR PREDICTION OF WOUND COMPLICATIONS DURING ORGAN-PRESERVING OPERATIONS IN PATIENTS WITH STAGE I-II BREAST CANCER, WITH TUMOR LOCALIZATION IN UPPER QUADRANTS Russian patent published in 2023 - IPC A61B5/01 A61B8/06 

FIELD: medicine; surgery; oncology.

SUBSTANCE: invention relates to medicine, namely to surgery and oncology; it can be used for prediction of the development of wound complications during organ-preserving operations in patients with stage I-II breast cancer with tumor localization in upper quadrants. For this purpose, a temperature in the area of the affected breast and tissues of the axillary region is determined in a patient, on the eve of surgical intervention, using a computer thermograph. At the same time, a local increase in a temperature in the area of supposed surgical intervention by a value of 1.7-2.5°C compared to a temperature outside the area of supposed operation indicates a smooth course of wound complications. A local temperature increase by less than 1.7°C or more than 2.5°C indicates an unfavorable course of wound complications in the area of operation. Then, during surgical intervention, after tumor removal and lymph dissection, a state of microcirculation in breast tissues and axillary tissues is assessed using LAKK-M device in a mode of laser Doppler flowmetry. In this case, a sensor is installed at a distance of 1.0 cm from edges of the wound, a perfusion index in the patient is recorded, taking values of the microcirculation index equal to 24.4-27.0 perfusion units as the norm. At the same time, perfusion units of less than 24.4 and more than 27.0 indicate an unfavorable course of wound complications; combined indicators of a local temperature increase in the range of 1.7-2.5°C and microcirculation indicators in the range of 24.4-27.0 perfusion units indicate a favorable course of wound complications, and values of a local temperature increase of less than 1.7°C and more than 2.5°C and microcirculation values of less than 24.4 and more than 27.0 indicate wound complications during organ-preserving operations.

EFFECT: invention allows for reliable and prompt prediction of the development of wound complications in this category of patients, which, in turn, allows for timely start of the treatment.
