Investigation for prognosis and correlation of therapeutic effect by preoperative chemotherapy and postoperative histopathological diagnosis
No longer recruiting／Ongoing trials
1. The usefulness of prediction about pCR of breast, axillary LN after PST using imaging diagnosis.
2. The association about evaluation of pCR and prognosis of PST.
to evaluate the imaging diagnosis after PST and pathological findings after surgery.
