Abstract

Rectal cancer is one of the deadliest cancers in Indonesia. Treatment of rectal cancer is often done with radiotherapy. External radiotherapy of rectal cancer uses linac which has several methods of irradiation. This study aims to determine the distribution of photon doses through the Conformity Index (CI) and Homogeneity Index (HI) values as well as the doses received by healthy tissue around cancer tissue. This study also aims to find out better methods of external radiotherapy. Making treatment planning using Xi-O TPS software. This study on the 3DCRT method produced HI values of 0.084 ± 0.017 and CI values of 0.98 ± 0.02. In the IMRT method, the HI value is 0.099 ± 0.028 and the CI value is 0.96 ± 0.03. Based on HI and CI analysis, it was found that the 3DCRT method was better than IMRT in the treatment of rectal cancer but not significantly. Meanwhile, the IMRT bowel bag method has a lower average dose compared to the 3DCRT method and the results are significant. In bladder and femoral tissues, the IMRT method is better than the 3DCRT method but is not significant. In rectal cancer, the IMRT technique is better because it can minimize the dose of OAR.

Abstract

The usage of homogeneous phantom in the calibration of LINAC is the standard in radiotherapy. However, a homogeneous phantom cannot accurately represent the complexity of the human body. This study was conducted to perform a Monte Carlo simulation of electron beam irradiation on an inhomogeneous phantom and then compare the resulting dose distribution values, in the form of PDD, with the PDD values obtained from a homogeneous phantom. Irradiation was performed with a 6.6 MeV electron beam on an inhomogeneous phantom resembling the human body. It was discovered that there is a significant difference between the R100 and R50 values of the inhomogeneous phantom in comparison to the homogeneous water phantom. The R100 value of the inhomogeneous value differs by 53.33% compared to the homogeneous phantom, while the R50 value differs by 41.07%. This indicates the influence of electron beam interaction with the inhomogeneous phantom on the resulting dose distribution. In the PDD curve, it is observed that the electron beam passing through the inhomogeneous medium experiences a greater loss of kinetic energy compared to the homogeneous medium. It was found that there’ a significant difference between the PDD values generated in the inhomogeneous phantom compared to the homogeneous phantom.
