medium · MCQ · Q-0B2D35
A 45-year-old woman undergoes core needle biopsy for a suspicious microcalcification cluster on mammography, which confirms Ductal Carcinoma In Situ (DCIS). What is the single most important factor determining the risk of local recurrence after breast-conserving surgery for DCIS?
- A.Patient age
- B.Surgical margin statusCorrect answer
- C.Presence of comedonecrosis
- D.Nuclear grade
Solution
Surgical margin status is the most critical determinant of local recurrence following breast-conserving surgery for DCIS. Achieving clear margins (typically at least 2 mm) significantly decreases the rate of local recurrence, regardless of other biological features like grade or comedonecrosis.
