脉络膜转移瘤是一种罕见的恶性肿瘤,近年来病例报告有所增多。该病发展很快,通常数日至数周,即可引起视网膜剥离、失明等严重并发症。本文报告1975年7月至1986年6月,日本癌症研究会附属医院放射科对确诊为脉络膜转移瘤患者行放射治疗的临床经验。治疗方法:患者30例,男4例,女26例,年龄32～77岁。其中27例(90.0%)进行了放射治疗。总剂量在20Gy 以上,用4.3MVX 线治疗者25例(83.3%),用12MeV 电子束治疗1例(3.3%);总剂量在20Gy 以下,用4.3MVX 线治疗1例(3.3%)。单次剂量2～3Gy,总剂量40～50Gy。如自觉症状改善不明显,可根据眼底情况再追加照射10Gy。照射时为避免射线损伤眼睛,应掌握水晶体位置、肿瘤发生部位。确定病灶,精心设计照射野,慎重考虑对病人的固定,保持病人在最佳的照射位置。对单侧患者,为包括尽可能多的视网膜,照射野的前缘应恰好通过晶体后缘,用单颞侧野2.5×3.0cm,头后倾10°,深度3 cm 照 Choroidal metastases is a rare malignancy that has been reported in recent years. The rapid development of the disease, usually a few days to several weeks, can cause retinal detachment, blindness and other serious complications. This article reports the clinical experience of radiation therapy in patients diagnosed with choroidal metastasis from July 1975 to June 1986 at the Japan Cancer Society Cancer Hospital. Treatment: 30 patients, 4 males and 26 females, aged 32 to 77 years. Among them, 27 cases (90.0%) underwent radiotherapy. The total dose was above 20Gy, with 25 cases (83.3%) treated with 4.3MVX line and 1 case (3.3%) treated with 12MeV electron beam. The total dose was below 20Gy and 1 case (3.3%) was treated with 4.3MVX line. A single dose of 2 ~ 3Gy, the total dose of 40 ~ 50Gy. Such as the improvement of symptoms is not obvious, according to fundus situation and then additional irradiation 10Gy. Irradiation to avoid ray damage to the eyes, should grasp the crystal body position, tumor site. Determine the lesion, carefully designed irradiation field, careful consideration of the patient fixed, to keep the patient in the best irradiation position. For unilateral patients, to include as many retinas as possible, the leading edge of the irradiation field should just pass the trailing edge of the lens, with a single temporal area of ​​2.5 × 3.0 cm, anterior-posterior 10 °, and a depth of 3 cm
