我院1986—1988年对3例白血病患者进行了大剂量化疗、大剂量全身照射(TBI)及同时进行胎肝和自体外周血干细胞移植。现将TBI情况报道如下: 例1.男、45岁,因确诊为单核细胞白血病,1985年4月14日入院。首次化疗缓解。1986年4月1日行TBI,分试照和正式照两次,放射源为~(60)Co。为创造TBI野,采用延长源皮距,机架旋转一定角度,机头与水平成10度角,使源皮距达2.40cm,用菱形野,边长100cm,对角线长120cm,分三个照射野:①前后正
In our hospital from 1986 to 1988, 3 cases of leukemia patients were treated with high-dose chemotherapy, high-dose whole body irradiation (TBI), and fetal liver and autologous peripheral blood stem cell transplantation. The TBI situation is reported as follows: Case 1. Male, 45 years old, diagnosed as monocytic leukemia on April 14, 1985. Remission of chemotherapy for the first time. The TBI was performed on April 1, 1986. The test was performed on two separate occasions and the official exposure was performed twice. The radiation source was ~(60)Co. In order to create TBI field, the source pitch is extended, the gantry rotates at a certain angle, the head and the plane are at an angle of 10 degrees, the source leather pitch is 2.40 cm, the diamond field is used, the side length is 100 cm, and the diagonal length is 120 cm. Radiation field: 1 positive and negative
