Abstract: (918 Views)
Background: Breast cancer (BC) is the second most frequent cancer in females worldwide. In recent years, the incidence rates of BC have been increasing among Iranian women. This study aimed to examine the incidence of BC among females in Kermanshah province, west of Iran, based on the data taken from the Kermanshah Population-based Cancer Registry (KPCR) during 2014-2017.
Methods: In this registry study, data were obtained from the KPCR, a high-quality cancer registry that collects data on various cancers using standard protocols all over Kermanshah province. The crude incidence rates (CRs) and age-standardized incidence rates (ASRs) of BC were determined per 105 person-years. Further, temporal trends were assessed using joinpoint regression analysis to describe the average annual percent change (AAPC) and 95% CIs. ArcGIS software was used to map the geographic distribution of BC incidence.
Results: During 2014-2017, 1,177 new cases of BC were detected in Kermanshah province. Most of the females diagnosed with BC (cases/100,000, percentage) lived in Kermanshah county (900, 76%) compared to the other counties (277, 23%). The overall ASR of BC increased by 38.7 cases per 100,000 females-year (AAPC: 2.2; 95%CI 5.1–10.1; p=0.3). The lowest and highest ASRs were observed in 2015 (36.7/100,000) and 2017 (40.7/100,000), respectively. The maximum incidence of BC among females was reported in the age group 45-49 years.
Conclusion: The BC trend for females increased from 2014 to 2017 in Kermanshah province across all age groups, especially in the age group 45-49 years. Thus, it is essential to take a series of effective health measures to prevent and control this cancer.
