Waldenstrom’s Macroglobulinemia treated with fractionated low-dose total body irradiation
Case Report: A 78-year-old male with relapsed Waldenstrom’s macroglobulinemia following therapy with chlorambucil underwent a five-week course of TBI. The total dose delivered was 1.5 Gy, given as 0.15 Gy twice weekly for ten sessions. During the course of therapy his CD4 cells increased from 637 (cells/mm3) to 808 partly through treatment and then declined to 654 at the completion of therapy. ...
متن کامل[Antitumor effects by low dose total body irradiation].
Total-body irradiation (TBI) with 0.02-0.25 Gy has been reported to have antitumor effects. In mice, low-dose TBI induces tumor growth delay, antimetastatic effects, suppressive effects on the incidence of spontaneous thymiclymphoma, sensitization of tumor to ionizing radiation, and decrease in TD50 value. In artificial metastasis, 0.20 Gy TBI suppressed lung metastasis when it was conducted be...
متن کاملDiode calibration for dose determination in total body irradiation
Background: Total Body Irradiation (TBI) is different from standard radiotherapy in many aspects, so it is not easy to predict the delivered dose to the patient under TBI treatment. Diode dosimetry procedures for surface dose reading can help to define variations of the actually delivered dose from the prescribed one. The aim of this study was to describe the measurements made to calib...
متن کاملEvaluation of dose uniformity in total body irradiation (TBI) technique in parallel-opposed anterior/posterior geometry using Varian Clinac 2100C/D linear accelerator
Background: Total body irradiation (TBI) is a technique that is commonly used as a part of the patient conditioning regimen before the bone marrow transplant (BMT). The purpose of this study is to introduce and implement a reasonable TBI technique on the human-like phantom in Imam Khomeini Hospital in Tehran. Methods: The present experimental study was conducted from October 2016 to November 2...
