Tumor Margin Skin Tattooing Before Neo-adjuvant Chemotherapy in Patients With Breast Cancer
Sponsor: All India Institute of Medical Sciences, Bhubaneswar
Summary
Study Description This prospective cohort study evaluates the feasibility and effectiveness of pre-neoadjuvant tumor localization using skin tattooing, with or without radiopaque clips, in patients with biopsy-proven T2-T3 breast cancer and axillary lymph node metastasis. 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/or 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.

Skin Tattooing of Tumor Margins Prior to Neoadjuvant Chemotherapy in Breast Cancer Patients: Prospective cohort study
Eligible patients with biopsy-proven breast cancer and axillary lymph node metastasis presenting with clinical T1-T2 disease will undergo localization of the primary tumor prior to initiation of neoadjuvant chemotherapy. The procedure will be performed with the patient in the supine position and the ipsilateral arm abducted to 90°, simulating the surgical position. Clinically palpable tumor margins will be identified and marked on the overlying skin using sterile permanent tattoo ink to delineate the pretreatment tumor boundaries. In patients with deep, poorly palpable, or mobile tumors, additional localization will be achieved by placement of radiopaque clips within the tumor under ultrasonographic guidance. Following localization, patients will receive standard neoadjuvant chemotherapy according to institutional protocols. Treatment response will be monitored clinically and radiologically, and the tattoo markings and/or clips will guide surgical planning for breast-conserving surgery
