Patients who have undergone mantle radiotherapy for Hodgkin's disease (HD) are at increased risk of developing breast cancer. In such patients, breast conserving surgery (BCS) followed by breast irradiation is generally considered contraindicated owing to the high cumulative radiation dose. Mastectomy is therefore recommended as the first option treatment in these women.
Six patients affected by early breast cancer previously treated with mantle radiation for HD underwent BCS associated with full-dose intraoperative radiotherapy with electrons (ELIOT).
A total dose of 21 Gy (prescribed at 90% isodose) in five cases and 17 Gy (at 100% isodose) in one case were delivered directly to the mammary gland without acute complications and with good cosmetic results. After an average of 30.8 months of follow up, no late sequelae were observed and the patients are free of disease.
In patients previously irradiated for HD, ELIOT can avoid repeat irradiation of the whole breast, permit BCS and decrease the number of avoidable mastectomies.
接受过霍奇金淋巴瘤(HD)斗篷野放疗的患者患乳腺癌的风险增加。在这类患者中,由于累积辐射剂量高,保乳手术(BCS)加乳腺照射通常被认为是禁忌的。因此,推荐乳房切除术作为这些女性的首选治疗方法。
6例曾因HD接受斗篷野放疗的早期乳腺癌患者接受了BCS联合电子术中全剂量放疗(ELIOT)。
5例患者乳腺直接接受了21 Gy的总剂量(规定在90%等剂量线上),1例患者接受了17 Gy(在100%等剂量线上),均无急性并发症,美容效果良好。平均随访30.8个月后,未观察到晚期后遗症,患者无疾病复发。
对于曾接受过HD放疗的患者,ELIOT可避免对整个乳房进行重复照射,允许进行BCS,并减少不必要的乳房切除术数量。
