Eligible patients will undergo tumor localization in the supine position with the ipsilateral arm abducted to 90°. Palpable tumor margins will be marked with sterile tattoo ink, and deep or mobile tumors will receive additional localization with ultrasonography-guided radiopaque clips. Following localization, patients will receive standard neoadjuvant chemotherapy. Tumor response will be monitored clinically and radiologically. Post-therapy, the tattoo markings and\u002For clips will guide breast-conserving surgery. Primary outcomes include feasibility of breast conservation, achievement of negative margins (R0 resection), and avoidance of mastectomy, while intraoperative technical challenges will also be documented.",[27,28,29],"Breast Cancer (Locally Advanced or Metastatic)","Tattoo Skin Markers","Neoadjuvant Chemoimmunotherapy","RECRUITING","2026-03-14",{"date":33,"type":34},"2026-03-18","ACTUAL",{"date":36,"type":34},"2025-09-10",{"date":38,"type":21},"2028-02-09",{"name":40,"class":41},"All India Institute of Medical Sciences, Bhubaneswar","OTHER",""]
