Volumetric modulated arc therapy treatment planning assessment for low-risk prostate cancer in radiotherapy

Aims: This research study was carried out for dose verification of volumetric modulated arc therapy (VMAT) plan in the patients of low-risk prostate cancer using different indices in radiotherapy. Materials and Methods: Twenty patients with low-risk prostate cancer after histopathological confirmation were included which were divided into two groups with prescribed dose of 7400 and 6000 cGy according to their disease and 3 mm sliced for each patient by computed tomography was obtained for planning. To evaluate the dose conformity and its distribution using VMAT plans such as homogeneity index (HI), radial dose HI, moderate dose HI, coverage, and uniformity index for each patient. These plans were constructed for each patient separately using Eclipse Treatment planning software. Statistical Analysis Used: Statistical Package for the Social Sciences statistical software is used to calculate mean standard deviation and standard error of all these indices. Results: Obtained results and findings enabled this research work to conclude that VMAT is a better treatment technique for the patients of low-risk prostate cancer with uniform dose distribution. Conclusion: It has been suggested that VMAT with Eclipse Treatment planning system is a good treatment modality to treat the patients of low-risk prostate cancer with better results.
