METHOD FOR DETERMINING THE AREA OF SKIN EDEMA IN PATIENTS WITH LOCALLY ADVANCED BREAST CANCER Russian patent published in 2022 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to oncology, and can be used to determine the area of ​​skin edema in patients with locally advanced breast cancer. A mammogram (MMG) is performed. The surface area of ​​the mammary gland is calculated using the formula S=2πrh, where S is the surface area of ​​the mammary gland, r is the radius, and h is the height. The area of ​​local edema is calculated by the formula Sl=((a1+a2)+(b1+b2))π/2, where S1 is the area of ​​local edema, a1 and a2 are the sides of the triangle in the frontal projection, b1 and b2 are the sides of the triangle in sagittal projection on MMG images. At the same time, the base of the triangle in the frontal and sagittal projections of the MMG is the segment that delimits the local edema from the mammary gland. The area of ​​breast skin edema S1 (%) is determined by the formula Sl(%)=(Sl/S)100%.

EFFECT: method allows to evaluate the dynamics of the tumor process against the background of neoadjuvant drug treatment by determining the area of the edema.
