METHOD OF PREDICTION OF POSTOPERATIVE COMPLICATIONS OF PATIENT UNDERWENT SURGICAL TREATMENT OF BREAST CANCER Russian patent published in 2019 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery, oncology, research medicine. Essential parameters of the patient's condition are assessed: surgical interventions (x₁), presence of chronic ischemic heart disease or cardiosclerosis (x₂), presence of varicose veins of lower extremities (x₃), presence of cerebrosclerosis (x₄), diabetes mellitus (x₅), preoperative course of radiation therapy (x₆), tumour size (x₇), thrombocytes (x₈, thousand in mcl), blood fibrinogen (x₉, g/l), administration of anticoagulants (x₁₀), age (x₁₁), tumour histological structure (x₁₂), degree of differentiation of tumour cells (x₁₃), molecular type of cancer (x₁₄), neoadjuvant chemotherapy (x₁₅), presence of obesity (x₁₆), presence of hypertensive disease (x₁₇), presence of regional metastases (x₁₈). Further, said parameters are evaluated in accordance with the table contained in the description. That is followed by diagnosing the predicted complication, namely: pyoinflammatory nature (P_pn), lymphocele (P_l), thrombophilia (P_th) and haemorrhage (P_h) according to the claimed formulas. Obtained values of patient diagnostic values are compared with interval values. High risk of the corresponding complication is predicted at 70.0≤P_pn≤90.7, 45.0≤P_l≤63.45, 50.0≤P_th≤89.27, 75.0≤P_h≤78.37, and low risk - at 4.94≤P_pn≤60.0, -14.02≤P_l≤30.0, 4.38≤P_th≤40.0, 4.61≤P_h≤60.0.

EFFECT: method provides higher accuracy and objectivity of prediction of postoperative complications in a patient suffering surgical treatment of breast cancer by evaluating complex of the most significant parameters.
