Investigation of the Effects of Biomaterials Used in Cranioplasty on Radiotherapy Dose Through the Monte Carlo Method

Öz

Aim: The gold standard in the treatment of brain tumors is radiotherapy and chemotherapy after surgery. Radiotherapy with high-energy ionizing radiation after surgery has an important place in the treatment of brain tumors. Implants with a high atomic number exhibit strong radiation attenuation and scattering properties that could potentially compromise the delivery of radiation therapy by distorting the dose distribution in and around the implant volume, complicating treatment planning in radiotherapy. In this study, it was aimed to investigate the interaction of biomaterials used in cranioplasty applications with X-rays used in radiotherapy using a GAMOS simulation. Methods: The head phantom defined in the GAMOS simulation includes, from left to right, 0.2 cm of skin, 0.3 cm of soft tissue, 1 cm of skull, 12 cm of brain, 1 cm of skull, 0.3 cm of soft tissue, and finally, 0.2 cm of skin. In order to observe the effect of different biomaterials, selected biomaterials (CCM alloy, stainless steel, alumina, NiTi alloy, titanium, PEEK, PMMA, and PTFE) were defined instead of a 1 cm skull. In this configuration, the brain tissue is also defined as the detector to absorb energy. Results: Cortical bone has a density of 1.920 g/cm3 and the dose taken by the brain tissue was found to be 4,843 Gy. It was observed that the dose value absorbed in the brain tissue decreased with the increase in the densities of the biomaterials used in cranioplasty. Dose results for PTFE and PEEK biomaterials were found to be close to bone tissue. Conclusion: As a result, PEEK and PMMA biomaterials, whose densities are very close to those of bone tissue, showed similarity to bone tissue in terms of radiotherapy dose distribution.
