In Regard to Tyler et al

To the Editor: The article by Tyler et al on tumor-free margin is an excellent and extensive study on its impact on local recurrence and on breast cancer–specific survival1 Both in the conclusion and in the discussion, authors report a lack of significant difference among negative, close, or positive margins regarding the aforementioned outcomes. It is important to note that entire the patient population (>10,000 patients) had postoperative whole breast radiation.
