Title

Measurement of ipsilateral lung and heart dose in radiotherapy of left sided mastectomy patients in common different clinical techniques: A phantom study

Pages

  389-394

Abstract

 Background: The aim of this study was to compare the radia on dose to ipsilateral lung and heart for different radiotherapy (RT) techniques including; two tangen al photon beams, electron therapy and combined photon-electron. Materials and Methods: Treatment planning of the men oned techniques on the CT images of a chest phantom was done using treatment planning system (TiGRT, Lina Tech, China). According to the plans, the phantom was irradiated with 6 MV photon and 10 MeV electron beams of Siemens Primus linac. Radia on dose was also measured using LiF Thermo Luminescence Dosimeter (TLD) which was placed inside 3 mm depth holes of ipsilateral lung and heart on the phantom. Results: The mean (± SD) radia on dose to the ipsilateral lung of the combined photon-electron was 66. 12 ± 5. 16% of prescribed dose. Whereas for the heart, it was 64. 05 ± 2. 62%. Mean (± SD) dose of ipsilateral lung and heart for electron irradia on was 54. 51 ± 3. 88 % and 34. 21 ± 3. 41%, respec vely. The mean (± SD) radia on dose to ipsilateral lung and heart of the tangen al was 50. 73 ± 3. 01 % and 31. 36 ± 3. 13%, respec vely. The mean (± SD) radia on dose to the chest wall-lung interface for electron therapy (72. 44 ± 2. 01 %) was significantly different in comparison with tangen al (65. 23± 4. 20%; p = 0. 045) and combined photon-electron (68. 14± 3. 53 %; p = 0. 032). Conclusion: Tangen al beams is more suitable for trea ng mastectomy pa ents compared to the other techniques such as electron therapy and combined photon-electron, due to lower radia on dose to pa ent's ipsilateral lung and heart.
