Dosimetric analysis of three-dimensional conformal radiotherapy, intensity-modulated radiotherapy-step and shoot, helical tomotherapy, and volumetric modulated arc therapy in prostate cancer radiotherapy

Conclusion: V75 Gy rectum bladder between 3D-CRT techniques differ significantly compared to the three other techniques and may not be suitable to the implementation of escalation doses. The HT technique produced the highest V5 Gy RVR and needed the highest monitor unit amount and the longest radiation duration. The VMAT technique was considered capable of realizing dose escalation in prostate cancer radiotherapy by minimizing toxicity in the rectum and bladder with the shortest radiation duration.
