Background: Wire localization (WL) is traditionally performed before excisional biopsy for patients with nonpalpable breast lesions, but it has several disadvantages. Our current study examines whether the method of radiocolloid combined with methylene dye localization (RCML) has an advantage over WL.
Materials And Methods: From August 2006 to May 2009, 157 patients with nonpalpable breast lesions classified as BI-RADS category 5 were enrolled in our study. Of the 157 patients, 78 were assigned to WL and 79 to RCML. The status of surgical margins, weight of specimens, length of incisions, and duration of operation were compared between these two groups.
Results: All patients were diagnosed after first excisional biopsy. The patients with malignancy accounted for 55.1% in WL group, and 53.2% in RCML group. For malignant lesions, fewer patients undergoing RCML had close or involved surgical margins than did those who had WL (19.0% vs. 39.5%, P = .038). The mean weight of specimen was 45.2 g in WL group and 39.0 g in RCML group (P < .001). The mean length of incision was 44.8 mm in WL group and 36.3 mm in RCML group (P < .001). The mean time of operation was 16.3 min for WL and 14.7 min for RCML (P = .001).
Conclusions: RCML provides precise identification of the site of the nonpalpable lesion and a visible marker to the lesion for surgeons and allows rapid, easy, and accurate excision of nonpalpable breast lesions. Therefore, RCML is a promising alternative to WL.

Background: Most breast cancers are detected at an early stage in which case conservative surgery is indicated. An accurate preoperative localization technique is essential for conservative surgery of non-palpable breast lesions. Currently, the gold standard technique is wire localization (WL).

Background: Intraoperative ultrasound-guided breast-conserving surgery guarantees real-time direct visualization of tumor and resection margins. We compared surgical, oncologic, and cosmetic outcomes between intraoperative ultrasound-guided breast-conserving surgery and traditional (palpation- or wire-guided) surgery across all breast cancer lesion types.
Methods: This prospective observational cohort study was conducted at the Veneto Institute of Oncology between January 2021 and October 2022.

The treatment of breast cancer during pregnancy requires careful consideration of consequences for both maternal and fetal health. In non-pregnant patients, the use of radioactive iodine-125 (125I)-seeds is standard practice for localising non-palpable breast tumors before breast-conserving surgery. However, the use of 125I-seeds in pregnant patients has been avoided due to concerns about fetal radiation exposure.

Purpose: To investigate the impact of artificial intelligence (AI) reading digital mammograms in increasing the chance of detecting missed breast cancer, by studying the AI- flagged early morphology indictors, overlooked by the radiologist, and correlating them with the missed cancer pathology types.
Methods And Materials: Mammograms done in 2020-2023, presenting breast carcinomas (n = 1998), were analyzed in concordance with the prior one year's result (2019-2022) assumed negative or benign. Present mammograms reviewed for the descriptors: asymmetry, distortion, mass, and microcalcifications.

Aim: This study aimed to detail our experience of using SCOUT® radar reflector for lesion localisation in the breast and axilla.
Materials And Methods: This is a prospective cohort study describing our clinical experience with the first 500 patients who received SCOUT® to localise lesions in the breast and axilla (from 23 July 2020 to 4 April 2022). Study measures include patient demographics, lesion location, diagnostic pathways (screening or symptomatic), imaging, and surgical and pathology outcomes.
