Disease recurrence in patients undergoing mastectomy for ductal carcinoma in situ.

Purpose: With DCIS incidence on the rise, up to 30% of patients undergo mastectomy for Ductal carcinoma in situ (DCIS) (Nash and Hwang, in: Ann Surg Oncol 30(6):3206-3214, 2023). Local recurrence rates after mastectomy for DCIS are reportedly low, but risk factors for recurrence are not known (Kim et al., in: J Cancer Res Ther 16(6):1197-1202, 2020).

Cost containment analysis of superparamagnetic iron oxide (SPIO) injection in patients with ductal carcinoma in situ.

Purpose: Recent studies have established the safety and efficacy of Superparamagnetic Iron Oxide (SPIO, Magtrace®) for delayed sentinel lymph node biopsy (SLNB) in patients with ductal carcinoma in situ (DCIS) who are undergoing mastectomy. The aim of our study was to measure cost containment with use of Magtrace® in comparison to upfront SLNB with traditional technetium-99 lymphatic tracer.

Methods: A total of 41 patients at our institution underwent mastectomy with Magtrace® injection for DCIS and were included in our single-institution, retrospective analysis.

Comparing Faculty and Trainee Evaluators of First-Year Resident Skills.

Objective: To determine if senior residents are comparable to faculty in assessing first-year resident skills on their overall assessment.

Background: As resident training moves towards a competency-based model, innovative approaches to evaluation and feedback through simulation need to be developed for both procedural as well as interpersonal and communication skills. In most areas of simulation, the faculty assess resident performance however; in clinical practice, first-year residents are often overseen and taught by senior residents.

Superparamagnetic iron oxide (SPIO) for axillary mapping in patients with ductal carcinoma in situ undergoing mastectomy: single-institution experience.

Purpose: Unnecessary axillary surgery can potentially be avoided in patients with DCIS undergoing mastectomy. Current guidelines recommend upfront sentinel lymph node biopsy during the index operation due to the potential of upstaging to invasive cancer. This study reviews a single institution's experience with de-escalating axillary surgery using superparamagnetic iron oxide dye for axillary mapping in patients undergoing mastectomy for DCIS.
