A multicenter high-quality data registry for advanced proton therapy approaches: the POWER registry
Paucity and low evidence-level data on proton therapy (PT) represent one of the main issues for the establishment of solid indications in the PT setting. Aim of the present registry, the POWER registry, is to pro... (Source: BMC Cancer)

Early effects of different brain radiotherapy modalities on circulating leucocyte subpopulations in rodents
CONCLUSIONS: Leucocyte subpopulations reacted differently to X-ray or proton brain irradiation. This difference could be partly explained by LN exposure to radiation dose. Further researches and analyses on other biological processes and interactions between leucocyte subpopulations are ongoing. The various mechanisms underlying leucocyte subpopulation changes under different irradiation modalities may have implications for the choice of radiotherapy modalities and their combination with immunotherapy in brain cancer treatment.PMID:38466699 | DOI:10.1080/09553002.2024.2324471 (Source: International Journal of Radiation Biology)

Comparing interplay effects in scanned proton therapy of lung cancer: Free breathing with various layer and volume rescanning versus respiratory gating with different gate widths
CONCLUSIONS: FB (L4V1) is the most efficient treatment, but not necessarily the optimal choice due to interplay effects. To satisfy both TT extensions and interplay, RG with a gate width as large as possible within safety limits is desirable.PMID:38461635 | DOI:10.1016/j.ejmp.2024.103323 (Source: Health Physics)

Comparing interplay effects in scanned proton therapy of lung cancer: Free breathing with various layer and volume rescanning versus respiratory gating with different gate widths
Pencil beam scanning (PBS) proton therapy significantly reduces the dose to normal tissue while maintaining uniform target coverage compared with passive scattering and intensity-modulated radiotherapy [1,2]. However, an active scanning beam for a moving tumor suffers from interplay effects [3]. A previous report showed that PBS plans with a commercial treatment planning system (TPS) do not consider interplay effects and may result in reduced target coverage and overdose to organs-at-risk (OARs) during actual irradiation [4].

Proton therapy induces a local microglial neuroimmune response
CONCLUSION: Overall, our data indicate that the brain responds in a similar manner to photons and plateau protons with a shared local upregulation of microglial priming-associated genes, potentially enhancing the immune response to subsequent inflammatory challenges.PMID:38453539 | DOI:10.1016/j.radonc.2024.110117 (Source: Radiotherapy and Oncology : journal of the European Society for Therapeutic Radiology and Oncology)

Proton therapy induces a local microglial neuroimmune response
Neurocognitive sequelae are the leading cause of a reduced quality of life in paediatric and adult primary brain and central nervous system tumour patients [1]. In addition, patients with brain metastases also experience debilitating neurocognitive impairment [2]. Although radiotherapy is an integral part of the treatment of brain tumours, it is associated with the development of neurocognitive side effects due to the co-irradiation of normal brain tissue [3]. Despite the introduction of 3D conformal radiotherapy and intensity-modulated radiotherapy, preventing or minimising radiotherapy-induced neurocognitive sequelae rem...
