Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Pathologic response-rate (increase in 90-100% tumor-cell loss) and/or pathological complete response (pCR) scored on the surgical tumor resection material. - objective response rate (ORR) assessed by MRI according to Response Evaluation Criteria In Solid Tumors (RECIST)1.1 criteria performed at baseline, after 4 ddAC cycles and at the end of chemotherapy. | — |
Secondary
| Measure | Time frame |
|---|---|
| - 3 and 5 year Event free survival (EFS) and overall survival (OS) - Adverse events >=grade 3 (maximum total) difference between treatment arms during ddAC, T and total duration of neoadjuvant chemotherapy. - QoL assessed using validated online questionnaires at T0, T1, T2 and T3. - Cognition assessed by the Amsterdam Cognition Scan (ACS) at T0, T2 and T3. This is a validated online cognitive test battery that can be completed at home. - Local immunomodulation and tumor immunity by analyzing the immune-composition and gene-expression profile using exploratory immune analyses, including multispectral imaging (e.g. Vectra) and transcriptomics using Nanostring in tumor samples taken at baseline (diagnostic), after 4 cycles and resection specimen. | — |
