| Abstract [eng] |
This study analysed demographic, anatomical, and clinical effects on irradiation doses of organs‑at‑risk (OARs) and secondary‑cancer risk for head and neck cancer cases. It was found that the incidence was highest among men aged 60–69, while excess absolute risk (EAR) analysis revealed a higher long‑term secondary‑cancer risk in advanced disease. In addition, out‑of‑field doses were measured and analysed based on anthropomorphic phantom SHANE and compared to treatment planning system (TPS) calculations, using two different calculation algorithms AAA and Acuros XB. It was observed that both algorithms underestimated the peripheral dose by 4% to 57.1%, particularly at distances farther from the edge of the irradiation field. |
