Autologous hematopoietic stem cell transplantation
Radiotherapy combined with autologous hematopoietic stem cell transplantation
Porting method melphalan: recommended dose of 70 mg/m2/day with 2 consecutive days (days -2 and -1) intravenous (IV) for more than 30 minutes each prior to autologous hematopoietic stem cell transplantation (ASCT, day 0).
TMI radiation dose On the 5th day (-5 days) before transplantation, an irradiation dose of 8 Gy is given. TMI uses a 6-18MV linear accelerator, the patient lies on his side in a single irradiation field, covered with a 1 cm thick plexiglass frame, and the radioactive source is 4 meters away from the body surface of the human side. The anterior and anterior positions were alternately irradiated, and the horizontal beam was irradiated in the opposite direction, and the actual irradiation dose was detected by the thermo-optical element of the 2570 roentgen dosimeter scale, and the irradiation dose of all parts of the body was adjusted to make the abdominal irradiation dose difference within 10%, the total dose was 8Gy, divided into 2 times a day, with an interval of 5 hours, and the dose rate was 4.99-6.96cGy/min.Porting method melphalan.
