Minor changes in the macrocyclic ligands but major consequences on the efficiency of gold nanoparticles designed for radiosensitization
2016
International audience; Many studies have been devoted to adapting the design of gold nanoparticles to efficiently exploit their promising capability to enhance the effects of radiotherapy. In particular, the addition of magnetic resonance imaging modality constitutes an attractive strategy for enhancing the selectivity of radiotherapy since it allows the determination of the most suited delay between the injection of nanoparticles and irradiation. This requires the functionalization of the gold core by an organic shell composed of thiolated gadolinium chelates. The risk of nephrogenic systemic fibrosis induced by the release of gadolinium ions should encourage the use of macrocyclic chelat…
Hypofractionnated radiotherapy for elderly patients with prostate cancer
2018
Radiation therapy technique and schedules could be adapted to patient's age because of a natural history of prostate cancer perceived as different, taking into account the comorbidities of patients but also a particular tolerance of elderly subjects. Thus, in localized prostate cancer, evaluation of associated diseases is essential before considering a treatment that will be of interest only if the life expectancy is greater than 10 years. When a curative approach is decided, radiotherapy holds a place of choice. Due to the recent results of randomized studies evaluating moderate hypofractionnated radiotherapy, showing a carcinological equivalence compared to a standard fractionation, this …
