Objective. The assessment of breast cancer survival rates and comparison with those of other countries may help to deepen knowledge among decision makers in the health care system and to improve the inequalities in accessibility to early detection and effective treatment. The aim of this study was to evaluate breast cancer survival rates in Kaunas region, Lithuania, and to compare them with those in the selected European countries.
Material and Methods. A retrospective study was carried out using medical records and data gathered from the Lithuanian Cancer Registry. A group of 240 patients with primary breast cancer diagnosed in 2008 in Kaunas region was analyzed. All causes of death were included in the analysis. The closing date of follow-up was September 30, 2010. Survival was determined using the life-table method and the Kaplan-Meier method. Cox proportional hazard models were used to estimate the effects of prognostic risk factors on survival.
Results. The median age of the patients was 63 years (range, 28–95). The 1-year and 2-year cumulative survival for breast cancer patients in Kaunas region, Lithuania, was 94.2% and 90.1%, respectively. As expected, the survival of patients with diagnosed advanced disease (stage III and IV) was significantly worse than that of patients with stage I (P<0.001) and II (P=0.003) disease. The screening group (aged 50–69 years) showed better survival in comparison with the group older than 69 years. Age, T4 tumor, and distant metastasis were the prognostic factors significantly associated with an increased relative mortality risk of breast cancer.
Conclusions
. Compared to the European survival rates, the 1-year and 2-year survival of patients with breast cancer in Lithuania was found to be similar to most European countries.
