Invasive local recurrence increased after radiation therapy for ductal carcinoma in situ.

Background: It is thought that equal numbers of invasive and noninvasive recurrences develop after conservative treatment for ductal carcinoma in situ. We analyzed our data to see if this was true.

Methods: A prospective database of 878 conservatively treated patients with ductal carcinoma in situ was analyzed.

The effect of systemic anticoagulation in patients undergoing angioaccess surgery.

The benefit of intravenous heparin as an anticoagulant to avoid thrombotic complications during angioaccess surgery for hemodialysis is unknown. We prospectively randomized 115 consecutive patients referred to our institution for permanent hemodialysis access to receive systemic anticoagulation or no anticoagulation during angioaccess surgery. Patient demographics, comorbid conditions, procedure time, complications, and patency were recorded in accordance with standards recommended by the Society for Vascular Surgery.
