Comparison of ultrasound guided surgery and radio-guided occult lesions localization (ROLL) for nonpalpable breast cancer excision.

Background: There is little literature comparing intraoperative ultrasound (IOUS) with radio-guided occult lesions localization (ROLL) in nonpalpable invasive tumors in breast conserving surgery (BCS). There is a need to compare these two methods in terms of safety and efficacy.

Methods: This is an observational cohort study.

When Is Sentinel Node Biopsy Indicated in High-Risk Ductal Carcinoma in situ? Four Hundred Sixty-Eight Cases from Three Institutions.

Introduction: Sentinel lymph node biopsy (SLNB) in ductal carcinoma in situ (DCIS) is not indicated. However, in certain cases (size >3 cm, high grade, mass effect on mammography, or palpable mass), it may be possible to find incidental invasive carcinoma (IC) that requires an SLNB. We studied the correlation of the aforesaid factors with the probability of finding IC in the surgical specimen.

Estimation of tumor size in breast cancer comparing clinical examination, mammography, ultrasound and MRI-correlation with the pathological analysis of the surgical specimen.

Background: To evaluate the best method in our center to measure preoperative tumor size in breast tumors, using as reference the tumor size in the postoperative surgical specimen. We compared physical examination . mammography .
