Brief Title: Validation of the CPS+EG, Neo-Bioscore and Modified Neo-Bioscore Staging Systems After PST of BC in China
Official Title: Validation of CPS+EG, Neo-Bioscore and Modified Neo-Bioscore Staging System After Preoperative Systemic Therapy of Breast Cancer in Multi-center in China
Study ID: NCT03437837
Brief Summary: Prognostic assessment after preoperative systemic therapy (PST) plays a vital role in breast cancer patients. The clinical-pathologic staging system incorporating estrogen receptor (ER)-negative disease and nuclear grade 3 tumor pathology (CPS+EG staging system) can effectively predict prognosis after PST. The Neo-Bioscore has been developed by the incorporation of the human epidermal growth factor receptor 2 (HER2) status into the CPS+EG staging system. But in a real world in China, the both staging systems had limits because of trastuzumab administration varied a lot in China from the United States. This retrospective study will validate CPS+EG and Neo-Bioscore system and explored a modified Neo-Bioscore system in multiple centers.
