What the trial is, and whether it could suit you
This is a single-center, interventional, prospective clinical study. A total of 45 patients aged ≥ 60 years with ECOG PS 0-1 who have histologically confirmed, treatment-naïve, unilateral primary invasive HER-2-positive breast cancer will be enrolled according to predefined inclusion/exclusion criteria. Participants will receive olaparib 300 mg orally twice daily combined with investigator-selected HP regimen (trastuzumab 8 mg/kg C1 → 6 mg/kg C2-6 and pertuzumab 840 mg C1 → 420 mg C2-6, both q3w) for up to six neoadjuvant cycles. Tumor response will be assessed after cycle 2; patients with inadequate response may switch to an alternative neoadjuvant regimen devised by the investigator for an additional 2-4 cycles before surgery, whereas responding patients will continue the original regimen to complete six cycles prior to surgery. Post-operatively, adjuvant therapy will be determined by
