Examining the Completeness of Breast Cancer Pathology Reports Registered in the Population-based Cancer Registration System and Spatial Analysis of the Incidence of this Cancer in Iran in 2016

Background: Breast cancer (BC) is a leading cause of cancer-related deaths among women worldwide, and its incidence has increased in Iran over recent years. Objectives: In this study, we aimed at assessing the completeness BC pathology reports population-based registration system perform spatial analysis 2016 to help policymakers develop targeted interventions. Methods: We conducted retrospective descriptive analysis, using secondary data from Integrated Cancer Information Management System, obtained 13789 all provinces 2016. Pathology data, including tumor type, site, size, pathologic T stage, N grade were examined for by age group. Results: 4000 with across selected study. The aging. addition, varied different variables. Accordingly, stage had highest lowest rates (100 % versus 27.4%), respectively. Spatial revealed significant high-risk areas incidence, Isfahan, Markazi, Chaharmahal Bakhtiari, Kohgiluyeh Boyer-Ahmad central Iran. contrast, North Khorasan was identified as low-risk area. Conclusions: Considering incompleteness report most variables registry, recognize gaps improve data. To ensure effective interventions control, tailored preventive measures are needed, particularly areas. Continuous evaluation completion, standard cellular reports, necessary accurate control
