| [Objective] Analyze the current status of breast cancer screening in Guangdong, explore the impact of different screening management models on screening status, and investigate optimal management models for breast cancer screening. [Methods] Based on the annual screening reports of cervical and breast cancer among women in 21 prefectures and cities of Guangdong Province from 2021 to 2023, regions were categorized into provincial project areas and non?project areas according to the screening management model. The χ2 test was used to compare population screening rates, mammography and pathological examination compliance rates, detection rates, and early diagnosis rates between the two regions. [Results] From 2021 to 2023, the screening rate of women participating in the free breast cancer screening program in Guangdong Province showed an increasing trend year by year (χ2 = 956,582.431, P < 0.001). The screening rate of breast cancer screening in non-project areas was generally higher than that in project areas. The compliance rate of histopathology in non-project area was 29.56%, lower than that in project area (χ2 = 18,416.611, P<0.001). The suspicious detection rate and positive detection rate of breast color ultrasound, suspicious detection rate and positive detection rate of breast X-ray examination and positive detection rate of histopathology in non-project areas were higher than those in project areas (P < 0.05). The detection rate of breast cancer in non-project areas was 104.04/105, which was lower than that in project areas (χ2 = 751.953, P<0.001). In recent three years, the early diagnosis rate of breast cancer screening in Guangdong Province increased year by year. The early diagnosis rate in non-project areas is 51.65%, which is lower than that in project areas (χ2 = 189.925, P<0.001). The treatment rate over the three years exceeded 90% in both regions, and the treatment rate in non-project areas was 96.20%, which was lower than that in project areas (χ2 = 52.256, P<0.001). [Conclusion] In Guangdong Province, the provincial project areas for breast cancer screening demonstrated higher pathological examination compliance rates, detection rates, and early diagnosis rates, as well as more effective treatment linkage. This indicates that standardized management and financial support are critical for improving screening quality, underscoring the importance of optimizing breast cancer screening management through experience synthesis. |
