Breast Cancer
Conditions
Brief summary
Achievement of pathologic complete response is important prognosticator to predict long term outcome in triple negative cancer. The efficacy of adding 4 cycles of cisplatin (CDDP4) is to be investigated whether addtional pathologic complete response is achieved for those triple negative breast cancer patients who recieved 4 cycles of adriamycin with cyclophosphamide(AC4) but did not reach clinical complete response during the course of neoadjuvant therapy.
Detailed description
First outcome measures (analysis) :at the time of surgery, Second outcome measures: 2019 August, 5 year Overall Survival, Disease free survival
Interventions
4 cycles of Adriamycin 60 mg/m2 and Cyclophosphamide 600 mg/m2 every 3 weeks 4 cycles of cisplatin 75 mg/m2 every 3 weeks

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| pathologic complete response (pCR) rate | up to 36 weeks | Rate of pCR (as defined by NSABP \[National Surgical Adjuvant Breast and Bowel Project\] criteria - absence of invasive disease in the breast \[ypT0\]) at the time of surgery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall response rate (ORR) by radiologic evaluation | up to 36 weeks | after completion of chemotherapy Overall objective clinical response rate = CR (complete response) + PR (partial response) rate, measured by US (or MRI) and assessed by Response Evaluation Criteria in Solid Tumors (RECIST) |
| Complete metabolic response (CMR) rate after 2 cycles of AC | up to 12 weeks | after 2 cycles of AC |
| 3 year disease free survival (3yr-DFS) | 3 years | — |
| Rate of breast conservation | up to 36 weeks | after surgery |
