Seven patients with large, pendulous breasts received external beam irradiation to the whole breast (50 Gy in 25 fractions plus boost) after lumpectomy. A special breast holding mask was shaped for each patient. Three-dimensional treatment plans and dose-volume histograms of the same patient with and without a mask were compared. Day-to-day variance was checked. This technique provides improvements in dose homogeneity, reproducibility, and sparing of normal tissues. Cosmetic outcome at present is good.
7例乳房较大且下垂的患者在肿块切除术后接受了全乳外照射（50 Gy，分25次照射加局部加量）。为每位患者定制了特殊的乳房固定面罩。比较了同一患者使用面罩和不使用面罩时的三维治疗计划和剂量体积直方图。检查了每日的差异。该技术在剂量均匀性、可重复性和正常组织保护方面有所改善。目前的美容效果良好。
