Perspectives and possibilities of preserving reproductive function in patients receiving antitumor treatment. Clinical observation

Currently, treatment of patients with early primary operable BRCA mutation-associated breast cancer requires integrative approach. A mutation in BRCA1/2 genes is a prognostically unfavorable factor increasing the risk of cancer of the contralateral breast, as well as ovaries, pancreas, fallopian tubes, and primary peritoneal cancer. In this clinical observation, an integrative multidisciplinary approach to treatment of a young patient with luminal B breast cancer is described which allowed to preserve the patient’s fertility and achieve pregnancy using assisted reproductive technologies.High effectiveness of the chosen treatment tactics in the framework of integrative approach in a specialized medical facility with experience in treatment of oncological diseases and preservation of reproductive function confirmed by clinical data and results of laboratory and instrumental exams is demonstrated.
