Abstract

Introduction: Population based breast cancer screening program was recently implemented in Turkey and is being performed for 40–69 years old women. The aim of this study was to document early results and evaluate the effectiveness of this program.

Materials-Methods: 348,638 women who were screened in 2016 were included in this study. All data was obtained from National centralized reporting system and from Cancer Registry database for end results. BI-RADS 1-2 was used for benign findings, and BI-RADS 0, 4 or 5 for recalls according to level of suspicion. The age distribution, recall rate, cancer detection and interval cancer rates were reviewed. The stages of detected cancers were evaluated and compared with that of nonscreened group in the same time interval.

Results: 43.2% of women were between 40-49 years old, and 56.8% were 50-69 in screening population. 70% of screen detected cancers were in age group of 50-69. Total recall rate was 5.6% (n=19,607). Malignancy rate was 70.2% for BI-RADS 5 recalls, 19.2% for BI-RADS 4, and 1.7% for BI-RADS 0 categories. The rate of screen-detected cancers was 3.2 per 1000 screening exams (n=1,120). The percentage of early stage disease was higher in screened group (54.3%) compared to nonscreened one (46.7%). In 231 women interval cancers were recorded (0.66 per 1000 screened women).

Conclusion: According to initial results, Turkey's newly implemented population based breast cancer screening program seems to be feasible and effective. This analysis suggests that breast cancer screening program should be continued with increasing coverage of target population.
