Abstract

Nowadays, the use of computed tomography (CT) simulation is getting widespread with the use of new treatment modalities like three dimensional conformal radiotherapy (3D-CRT), intensity modulated radiotherapy (IMRT), adaptive radiotherapy (ART) and stereotactic radiosurgery (SRS) in radiotherapy facilities. The main purpose of these new treatment modalities are to increase the survival and increase the quality of life by reducing the side effects. However, radiation induced secondary malignancy risk is getting important after radiotherapy with the increase in survival. Especially, CT scanning was performed from head to sacral region for 3DCRT craniospinal treatments techniques in children or young patients and several precautions should be taken to reduce the radiation dose due to the CT simulation. In this study, we measured organ equivalent dose in Alderson Rando phantom and we estimate radiation-induced cancer risk due to CT scanning for different conditions. According to our measurement, secondary malignancy risk was found to be between 0.10% - 0.22% for different conditions in craniospinal CT simulation.

Özet

Günümüzde radyoterapi uygulamalarında üç boyutlu konformal radyoterapi (3B KRT), yoğunluk ayarlı radyoterapi (YART), adaptif radyoterapi (ART) ve stereotaktik radyocerrahi (SRC) gibi yeni tedavi modaliteleri ile birlikte bilgisayarlı tomografi (BT) simülasyonunun kullanımı da yaygın olarak artmaktadır. Artan sağkalım süresi ile birlikte de radyasyondan kaynaklı ikincil kanser riski önem kazanmaktadır. Özellikle de pediatrik hastalarda BT simülasyonundan kaynaklı dozu minimize etmek amacı ile çeşitli önlemlerin alınması gerekmektedir. Bizim çalışmamızda ise üç boyutlu kraniyospinal radyoterapi uygulanan pediatrik olgularda BT simülasyonundan kaynaklı çevre organların aldığı doz değerleri ve yaşam süresi boyunca düşük doz radyasyondan kaynaklı ikincil kanser riskinin değerlendirilmesi amacı ile Alderson Rando fantomda ölçümler alındı. Ölçümler sonucunda farklı ölçüm koşullarında (tüp voltajı, kesit kalınlığı gibi) kraniospinal radyoterapi uygulamaları için gerçekleştirilen BT simülasyonundan kaynaklı ikincil kanser riski 0.10% - 0.22% değerleri arasında bulundu.
