title: [Evaluation of breast conserving therapy (BCT) standards for invasive and preinvasive breast cancer adapted in RCO in Bydgoszcz].
abstract: BACKGROUND
  Prophylactic campaign against breast cancer wide spread by Regional Center of Oncology made significant influx of patients coming to our place and presenting less advanced stages of the mentioned disease.
  
  
  OBJECTIVE
  The aim of this work was estimate of BCT treatment standard for invasivum cancer and preinvasivunm breast cancer treatment standard which was adapted in RCO.
  
  
  METHODS
  Patients presenting unifocal invasive cancer smaller than 2 cm, stage No, where the minimal margin of more than 1 cm was possible to perform, were qualified to BCT. Minimal surgical border during tumorectomy was 1 cm. We were excluded patients with carcinoma lobulare and carcinoma mucinosum. During qualification to DCIS treatment standard first we must exclusion multifocalis cases based on Anderson classification and Falun consens. In the other cases we based on Van Nuys Prognostic Index (VNPI) considering the patient's age. We have 3 forms of treatment: simplex mastectomy, tumorectomy and tumorectomy with RTG-therapy. To BCT standard were qualified 52 patients. Schematically was attended 45 peoples. We had 5 patients which was attended based on preinvasivum breast cancer treatment standard.
  
  
  RESULTS
  The size of breast cancer tumor at the patients which was attended based on BCT standard was 0,5-2 cm. 3 patients was disqualified from BCT because we found second breast cancer focus in histopathological material. We must widen surgical border post tumorectomy in 5 cases. Among 5 patients with preinvasivum cancer was 3 simplex mastectomy and 2 cases tumorectomy with RTG-therapy.
  
  
  CONCLUSIONS
  In our opinion BCT treatment standard and breast preinvasivum cancer treatment standard should be using only in high specialty oncological center. It is a guaranty of right qualification and treatment for breast cancer patients.
