Abstract 4042


Pathologic complete response (pCR) after neoadjuvant chemotherapy (NACT) is associated with superior disease free (DFS) and overall survival (OS). This association is strongest in triple-negative breast cancer (TNBC). The CPS+EG system, based on pre-treatment clinical (CS) and post-treatment pathologic stage (PS), grade and estrogen receptor status, leads to a refined estimate of prognosis after NACT in all comers and HR+/HER2- (Marmé et al Eur J Cancer 2016). Here we investigate if CPS+EG scoring provides a superior estimate of prognosis in TNBC after NACT to select patients (pts) for post-neoadjuvant therapy.


We calculated the CPS+EG score for 1795 pts with TNBC from 9 prospective German trials. Pts with missing variables were excluded. 5-year DFS estimates were calculated using the Kaplan Meier method.


Pts who achieved a pCR had a 5-year DFS of 86% (n = 822, 45.8%), whereas pts with residual stage I had a 5-yr DFS of 77.5% (n = 383; 21.3%). CPS+EG score was unable to identify non-pCR pts with a sufficiently good prognosis, to avoid post neoadjuvant therapy. The best prognostic CPS+EG groups (score 1/2) in non-pCR pts had a 5-year DFS of 77.5% and 74.4%, respectively (n = 362; 37.2%). CPS+EG identified a small group (n = 26; 3.2%) at high risk of recurrence despite pCR, mainly based on initial stage (CS+EG score > 3; 5-year DFS 61.4%) that might benefit from additional treatment. However, prognosis of pts with a CPS+EG score of 3 (5-year DFS: 64%), could be further discriminated by pCR (5-year DFS: 83.9% vs 49.7%). Detailed results are presented in the Table.Table:


pathologic stage: All patientsCPS+EG: All patientsCPS+EG: non-pCR patientsCPS+EG: pCR patients
PS (N = 1795)5-year DFS rate*95% CIN%CPS-EG (N = 1795)5-year DFS rate*95% CIN%CPS-EG (N = 973)5-year DFS rate*95% CIN%CPS-EG (N = 822)5-year DFS rate*95% CIN%


pCR remains the strongest and most clinically useful prognostic factor after NACT in TNBC. The CPS-EG score does not add additional information beyond pCR and ypT/N staging in TNBC patients. Other factors than those used beyond staging might be needed in TNBC.
