Hui Hu, Wei Wei, Xin Yi, Ling Xin, Yinhua Liu


Background: The aim was to study the clinical utility of AJCC 8th edition prognostic stage system for patients with breast cancer.

Methods: According to the AJCC 8th edition cancer staging system, a total of 784 patients with breast cancer diagnosed by Department of Breast Surgery in Peking University Shenzhen Hospital from January 2011 to June 2016 were analyzed in anatomic and prognostic stage.

Results: Five hundred and five (64.4%) patients prognosis staging changed compared with anatomic stage. Among them, 63 (33.5%) patients were in stage I, 295 (73.8%) patients in stage II, and 128 (72.7%) patients in stage III according to anatomic stage, respectively. The distribution and variety of the anatomic and prognostic stage differ in intrinsic subtypes of breast cancer (P < 0.001).

Conclusion: AJCC 8th edition cancer staging system is an important prognostic factor for disease outcome of breast cancer.
