Following the requirements of Breast Cancer Centre-bettering outcomes of the treatment of the patients with a breast cancer

Introduction
On 20 April 2015 the Breast Cancer Unit of Holycross Cancer Centre (HCC) in Kielce was granted with the certificate of the Senologic International Society (SIS), confirming the completion of quality criteria in diagnostics and therapy of patients with breast cancer (BC). In 2014 HCC strove to diagnose and treat patients with breast cancer following the commendations of the SIS.

Aim
In this paper we provide the actualised outcomes of treatment after a 5-year observation.

Material and methods
In 2014 a total of 409 women were qualified to radical treatment of invasive cancer in Holycross Cancer Centre. The median time of observation was 60 months. The probability of disease-free survival and overall survival was estimated by the Kaplan-Meier method.

Results
Five-year disease-free survival (DFS) and overall survival (OS) for an entire group was 94% and 90%, respectively. DFS for women from pre-screening, screening, and post-screening age groups were 90%, 93%, and 89% and OS 89%, 90%, and 79%, respectively; DFS in patients with stage I, II, III, and IV was 98%, 95%, 76%, and 20%, respectively and OS 97%, 91%, 70%, and 20%, respectively.

Conclusions
We believe that proper coordination and cooperation between specialists who are engaged in the process of diagnostics and treatment of women with breast cancer is an important factor leading to improved outcomes of treatment.
