title: [PRIMARY CYTOREDUCTIVE SURGERY VERSUS NEOADJUVANT CHEMOTHERARY IN TREATMENT OF ADVANCED OVARIAN CANCER (STAGE III C-IV). OUR AND FOREIGN EXPERIENCE].
abstract: BACKGROUND
  The advanced ovarian cancer usually have bad prognosis. The main methods for treatment of these types of tumors are: primary cytoreductive surgery and platin-based chemotherapy.
  
  
  OBJECTIVE
  Our aim was to evaluate our and foreign experience in treatment of advanced ovarian cancer stage III C--IV treated by neodjuvant chemotherapy followed by cytoreductive surgery and patients treated by primary cytoreductive surgery followed by adjuvant chemotherapy. We wanted to research the survival rate, postoperative adverse effects, mortality rate, the size of residual tumor and the metastases in these patients.
  
  
  METHODS
  We researched for 10 years period--50 patients treated by primary cytoreductive surgery and 50 patients treated by neoadjuvant chemotherapy.
  
  
  RESULTS
  The postoperative adverse effects and mortality rate are lower by neoadjuvant chemotherapy followed by cytoreductive surgery. The most important independent prognostic factor for overall survival rate was the lack of residual tumor in both types of treatment.
  
  
  CONCLUSIONS
  The neoadjuvant chemotherapy followed by cytoreductive surgery in ovarian cancer stage III C--IV is considered as a standard treatment.
