EVALUATION OF THE SYSTEMIC AND REGIONAL ANTIBIOTIC THERAPY EFFECTIVENESS AS PART OF COMPLEX THERAPY IN PATIENTS WITH LOCALLY SPREAD BREAST CANCER

In recent years, breast cancer is the most common oncologic pathology and the most common cause of disability among women in developed countries.

The aim of the study. To improve direct and long-term results of treatment in patients with locally spread forms of breast cancer (LSBC) by accelerated regression of perifocal inflammatory changes using selective intraarterial application of antibiotics; improving patients’ quality of life.

Materials and methods. The main sample consisted of 109 patients.The control group included 65 (61 %) clinical cases of LSBC who were performed series of courses of intravenous systemic polychemotherapy (SPHT) as neoadjuvant therapy accompanied by systemic intravenous antibiotic therapy. The study group consisted of 42 (39 %) patients who were performed selective intraarterial neoadjuvant polychemotherapy course with simultaneous regional use of antibiotic therapy in the intraarterial administration.

Results. The regional administration of antibiotics as a part of the complex neoadjuvant therapy, along with the method of selective intraarterial polychemotherapy, has a positive effect on the linear and chronometric regression of perifocal inflammatory changes around the focus of the primary inoperable LSBC, which positively affects the somatic and psychological patient's state and increases the quality of his life.

Conclusions. The complex regional impact on the affected organ has a statistically confirmed better effect with bright holistic features, demonstrating the additive synergism of selective techniques.The selective intraarterial antibiotic therapy does not require additional time and material costs while increasing the efficiency of the method. The versatile advanced approach positively affects the somatic and psychological state of the patient.
