At the conclusion of a recent office visit, one of our patients summarized his feelings and stated, with a sense of absolute conviction, “The only type of radiation therapy I am willing to undergo is proton therapy.” In contrast, another recent patient facing a similar situation stated, “I don't care which I get [proton or photon therapy]; to me, it sounds like it's the team, not the beam.” The former patient put his hope in a technology; the latter patient prioritized the experience of his care team over any particular technology.

CONCLUSIONS: IMPT following IBR spared underlying organs and had low rates of acute toxicity. Reconstruction complications are more common in irradiated breasts, and reconstructive outcomes appear comparable with photon literature. Hypofractionation was associated with higher reconstruction failure rates. Further investigation of optimal dose-fractionation after IBR is needed. PMID: 31185327 [PubMed - as supplied by publisher]

Proton Computed Tomography (proton CT) is an imaging modality able to measure the proton stopping power of the patient prior to treatment planning and treatment in proton therapy [1]. The goal of proton CT is to increase the accuracy of the proton range estimation, compared to conversion from the X-ray mass attenuation using X-ray CT [2]. Several design approaches for proton CT have been proposed. Usually, tracker planes in front of and behind the patient measure each proton ’s position and direction so that their path through the patient can be estimated [3,4].

Conclusions: Our initial results with the use of modern PT for reirradiation of recurrent NPC patients are encouraging. Favorable LC and OS rates were obtained at the cost of acceptable severe late toxicity. PMID: 31155998 [PubMed - as supplied by publisher]

An international group of 22 liver cancer experts from 18 institutions met in Miami, Florida to discuss the optimal utilization of proton beam therapy (PBT) for primary and metastatic liver cancer. There was consensus that PBT may be preferred for liver cancer patients expected to have a suboptimal therapeutic ratio from XRT, but that PBT should not be preferred for all patients. Various clinical scenarios demonstrating appropriateness of PBT versus XRT were reviewed.

Abstract The fine, sub-millimeter sized structure of lung tissue causes a degradation of the Bragg peak curve in particle therapy. The Bragg peak is degraded because particles of the same energy traverse lung tissue of different compositions of high and low density materials. Hence, they experience different energy losses resulting in variable ranges and a broadened Bragg peak. 
 Since this fine structure of lung tissue is not resolved in standard treatment-planning CTs, current state-of-the-art dose calculation procedures used in the clinical routine are unable to account for this degradation. Neglecting ...

It is critical that rigorous evaluation of technology in radiation oncology be undertaken during the early stages of implementation or when there is a marked cost differential. Prospective clinical data proving the clinical effectiveness of emerging technology may not be available to guide proper investment and development. In these scenarios, models can be used to simulate expected clinical outcomes and predict comparative effectiveness and cost-effectiveness.1 In this edition of the Red Journal, 2 studies use model-based approaches to compare photon intensity modulated radiation therapy (IMRT) to proton beam therapy (PBT...
