ABSTRACT

Purpose: To increase the radiation therapy efficacy in breast cancer patients.

Material and methods: The study included 53 patients with verified breast cancer in stages T_1–2N_0–micM₀ treated in 2008–2013. The median age of the patients was 65 years. Median follow-up study for 30 months was conducted. The patients were undergone to organ-preserving treatment, including radical resection followed with accelerated partial radiation therapy. This method of radiation therapy was used in patients who were carefully selected accordingly to strict criteria. For a clear visualization and adequately determine the volume of the tissue irradiated in 92 % of patients the clipping of bed removed tumor was held using metal clips. All patients had conformal radiation therapy: 2,5 Gy twice a day, daily dose of 5 Gy, (for16 days) summary dose 40 Gy. The criteria of patients selecting to this method of radiation therapy and results of randomized controlled trials are described.

Results: Within a median follow-up study for 30 months, no local and loco-regional recurrences, as well as distant metastases were observed.

Conclusion: Proposed method of accelerated partial breast irradiation of patients with early breast cancer carefully selected shows the results comparable with those of the entire remaining breast exposure.

Key words: radiotherapy, breast cancer, local recurrens, accelerated partial irradiation
