The percentage of unnecessary mastectomy due to false size prediction using preoperative ultrasonography and MRI in breast cancer patients who underwent neoadjuvant chemotherapy: a prospective cohort study.

Background: Imaging-estimated tumour extent after neoadjuvant chemotherapy tends to be discordant with the pathological extent. The authors aimed to prospectively determine the proportion of decisions regarding total mastectomy for potential breast-conserving surgery candidates owing to false size prediction with imaging in neoadjuvant chemotherapy and non-neoadjuvant chemotherapy patients.

Materials And Methods: The authors prospectively enroled clinical stage II or III breast cancer patients who are scheduled for total mastectomy between 2018 and 2021.

Comparison of Quality of Life and Cosmetic Outcome of Latissimus Dorsi Mini-Flap With Breast Conservation Surgery Without Reconstruction.

Purpose: Latissimus dorsi mini-flap (LDMF) reconstruction after breast-conserving surgery (BCS) is a useful volume replacement technique when a large tumor is located in the upper or outer portion of the breast. However, few studies have reported the impact of LDMF on patients' quality of life (QoL) and cosmesis compared with conventional BCS.

Methods: We identified patients who underwent BCS with or without LDMF between 2010 and 2020 at a single center.

Survival analysis of breast cancer patients after diagnosis of second primary malignancies, focusing on the second primary hematologic malignancy.

Purpose: Although the overall survival (OS) of breast cancer patients is increasing with improved detection and therapies, so is the risk of breast cancer patients developing subsequent malignancies. We investigated the OS of breast cancer survivors according to sites of second primary malignancies (SPM). The OS of the second primary hematologic malignancy (SPHM) was then compared with that of metastatic breast cancer (MBC).

Ingestion of multiple magnets in children.

Background: The ingestion of multiple magnets is harmful in children because it can cause intestinal obstruction and/or perforation. We present an approach for the management of children visiting the emergency department with multiple magnet ingestion.

Methods: We retrospectively investigated 9 children who presented to 2 centers in Korea between January 2004 and August 2018 with a history of multiple magnet ingestion.
