A Three-Dimensional Bioabsorbable Tissue Marker for Volume Replacement and Radiation Planning: A Multicenter Study of Surgical and Patient-Reported Outcomes for 818 Patients with Breast Cancer.

Background: Accurate identification of the tumor bed after breast-conserving surgery (BCS) ensures appropriate radiation to the tumor bed while minimizing normal tissue exposure. The BioZorb three-dimensional (3D) bioabsorbable tissue marker provides a reliable target for radiation therapy (RT) planning and follow-up evaluation while serving as a scaffold to maintain breast contour.

Methods: After informed consent, 818 patients (826 breasts) implanted with the BioZorb at 14 U.

Small cell carcinoma of the head and neck: the university of Miami experience.

Purpose: To describe the University of Miami experience in the treatment of small cell carcinoma of the head and neck.

Methods And Materials: A total of 12 patients with nonmetastatic small cell carcinoma of the head and neck were treated between April 1987 and September 2007. Radiotherapy was the primary local treatment modality for 8 patients.
