Abstract 160O


GeparOcto investigated dose-dense NACT with intense dose-dense epirubicin, paclitaxel, cyclophosphamide (iddEPC) and PM(Cb) in high-risk early BC. Primary endpoint pathological complete response (pCR; ypT0/is ypN0) was comparable in the whole cohort as well as in subgroups (Schneeweiss et al. EJC 2019). Here, we report the secondary endpoints invasive disease-free survival (iDFS) and overall survival (OS).


Pts were randomized (stratified by BC subtype, Ki67, lymphocyte-predominant BC) to receive 18 weeks of E (150 mg/m2) followed by P (225 mg/m2) followed by C (2000 mg/m2), each q2w for 3 cycles or weekly P (80 mg/m2) plus M (20 mg/m2) plus, in TNBC, Cb (AUC 1.5). HER2+ BC pts additionally received trastuzumab (6 [loading dose 8]mg/kg q3w) and pertuzumab (420 [840]mg q3w) with all P and C cycles. Adjuvant locoregional and endocrine therapy were given according to national guidelines. Secondary time-to-event endpoints were iDFS and OS.


Between 12/2014 and 06/2016, a total of 961 pts were randomized and 945 started treatment (iddEPC n=470, PM(Cb) n=475). After a median follow-up of 47.0 (range 1.6-61.5) months, 75 iDFS events in iddEPC and 87 in PM(Cb) were reported. Overall, there was no difference in iDFS (hazard ratio PM(Cb) to iddEPC 1.16, 95%CI 0.85-1.59, p=0.3357) or OS (hazard ratio 0.90, 95%CI 0.58-1.40, p=0.6371) between both arms. In the subgroup of hormone-receptor (HR)+/HER2- BC, iDFS was significantly longer for iddEPC (4-year iDFS 62.5% with PM vs.77.9% with iddEPC; hazard ratio 2.11, 95%CI 1.08-4.10, p=0.0284), translating into an OS benefit (4-year OS 80.1% vs. 94.7%; hazard ratio 3.26, 95%CI 1.06-10.00, p=0.0388). There was no significant difference in survival in HER2+ or TNBC.


While there was no difference in survival following NACT with iddEPC or PM(Cb) for the entire cohort, the subgroup of HR+/HER2- BC significantly benefits from treatment with iddEPC. This supports the concept of effective therapy beyond pCR in luminal BC pts.
