Breast cancer is the most common malignant disease in women accounting for 23 % of all female malignancies. In 2007, its incidence in the Czech Republic exceeded 120 cases per 100,000 women, placing the country among those with the highest detection rates for this condition. Despite an ever-increasing incidence, the mortality rates for breast cancer show a stable or even slightly decreasing trend because of the availability of modern diagnostic and therapeutic modalities (1). Total mastectomy and complete axillary lymph node dissection was a traditional therapeutic approach throughout the twentieth century. This therapeutic strategy was derived from Halsted's belief that breast cancer was a localized disease which could be managed with radical (or super-radical) locoregional therapy (2, 3). At present, there is no doubt about the primary systemic nature of breast malignancies and the approach to treatment of this condition has changed substantially. There is a clear trend towards less radical surgery. Ablations have been largely replaced by breast-conserving procedures, usually followed by adjuvant radiotherapy; the proportion of these partial procedures is further increasing due to the use of neoadjuvant therapy. Currently, sentinel lymph node biopsy (SLNB) is a widely accepted standard for early breast cancer in axillary surgery. Sentinel lymph node is defined as the first lymph node (or group of lymph nodes) to receive lymphatic drainage from a primary tumour, thus representing the first site of lymphatic spread of the tumour. The status of the axillary lymph nodes is the most important single prognostic factor for the overall survival rate of patients with breast cancer (4, 5). It has been repeatedly shown that sentinel lymph node biopsy is a very sensitive and accurate method to evaluate the lymph node status in women with early breast cancer (6, 7). In women with a negative finding in the sentinel lymph node, no further surgical intervention in the axilla is indicated according to the NSABP B-32 study (6).
Breast cancer screening in the Czech Republic: Results from mammographic screening centers 2003-2009 [Screening nádorů prsu v České Republice: Výsledky fungování akreditovaných mamodiagnostických screeningových center za období 2003-2009]

In the Czech Republic breast cancer screening program has been functional since 2003. Till the end of 2009 2 518 710 asymptomatic women have been mammographically examined. In this screening program 12,063 breast cancers have been detected with 70 % of them in early T1 and Tis stages. This study explains quality control criteria applied and regularly checked in 66 screening centers and suggests new options for increase of participation of women in the screening above current 50 % as well as other supportive ways to stabilize the program, which is aimed on reduction of breast cancer mortality.
