Proton-Beam vs Intensity-Modulated Radiation Therapy: Too Soon for a Randomized Trial

June 01, 2008

The authors address the “theoretical” advantages of protons vs photons as well as what they consider to be key issues and uncertainties in proton therapy. Essentially, the paper concedes certain advantages of proton therapy, such as its high degree of conformability with the use of fewer beams and its reduced-volume integral dose with respect to intensity-modulated x-ray therapy (IMXT), and notes some future directions in proton therapy in terms of partial prostate boosting, intensity-modulated proton therapy (IMPT), and in vivo dosimetry verification with positron-emission tomography (PET).
