Recurrences and edges of R1 resection depending on histological characteristics and molecular biological types of breast cancer; [Рецидивы и края резекции R1 в зависимости от гистологических характеристик и молекулярно-биологических типов рака молочной железы]

The article presents literature data with an assessment of histological features, molecular biological type? of breast cancer, namely their impact on the risk of relapse or detection of Rl. The volume of surgical intervention and the risk of relapse are considered. The age of the patients, histological characteristics (multicentricity, multifocality), mutations on the risk of relapse were analyzed. It is known that when a recurrence of breast cancer is detected, the risk of further metastasis increases, and the overall survival rate decreases accordingly. The early and late recurrences of breast cancer were analyzed. © 2022 Izdatel'stvo Meditsina. All rights reserved.
