Breast-conserving surgery for primary breast cancer: necessity for surgical clips to define the tumor bed for radiation planning.
Hunter MA, McFall TA, Hehr KA
Radiology. 1996;200(1):281.
Radiographs obtained at definitive and boost irradiation in 50 patients with stage I-II breast cancer were retrospectively examined. Tangent target fields planned on the basis of surgical clips placed at excision biopsy were evaluated with simulation radiographs. Four (8%) of 50 tangent target fields would have been inadequate without clips, and 23 (46%) of the boost targets would have been missed (12 [24%], totally; 11 (22%), marginally). Radiopaque surgical clips placed at excision biopsy help plan boost-irradiation target fields.
