Modelling geometric uncertainties in prostate radiotherapy
Image guided radiotherapy (IGRT) presents a range of techniques to enhance thegeometric accuracy of radiotherapy treatment. A full evaluation of such techniques,against increased cost, workload, or unnecessary radiation dose, would require theincorporation of geometric errors into existing methods …

Accumulating delivered dose to the rectum to improve toxicity prediction in prostate radiotherapy
… to the rectum to improve toxicity prediction in prostate radiotherapy Leila E. A. Shelley Gastrointestinal (GI) toxicity is a clinical issue suffered by up to 22% of prostate cancer radiotherapy patients. However, the relationship between radiation dose and toxicity is generally poorly …

Risk of Second Malignant Neoplasms Following Proton Arc Therapy and Volumetric Modulated Arc Therapy For Prostate Cancer
… of second malignant neoplasms (SMNs) following prostate radiotherapy is a concern due to the large population of survivors and decreasing age at diagnosis. It is known that parallel-opposed beam proton therapy carries a lower risk than photon IMRT. However, a comparison of SMN risk following …

Dynamics and utility of cell-free DNA release following radiotherapy in prostate cancer and non-small cell lung cancer
… To evaluate the dynamics of cfDNA during radical radiotherapy, total cfDNA was quantified in patients undergoing radiotherapy for prostate and lung cancer; samples from a sub-cohort underwent methylation analysis and NGS. METHODS: Analysis of blood plasma cfDNA was carried out on samples from …

Towards Offline Adaptive Therapy for Prostate Patients using Velocity
… of three offline adaptive workflows for prostate radiotherapy (RT) through a retrospective study, potentially allowing future offline dose assessment and adaptive replanning for prostate bed RT. We investigated an offline adaptive therapy workflow previously developed for head-and-neck …

In Vivo Dosimetry Using Plastic Scintillation Detectors For External Beam Radiation Therapy
… intensity modulated radiation therapy for prostate cancer. This was done as part of an Institutional Review Board approved protocol. PSDs were attached to endorectal balloons used routinely during prostate radiotherapy, positioning the detectors in close proximity with the rectal wall. Two …

Numerical modelling of bladder filling and prostate positioning in modern radiotherapy
… organs, in particular the position of the prostate that can influence the diagnosis and planning of radiotherapy treatments of prostate cancer. The success of prostate radiotherapy depends on the delivery of high doses of radiation to a defined tissue volume with a high degree of positional …

Evaluation of an End-to-End Radiotherapy Treatment Planning Pipeline for Prostate Cancer
… reference to surrounding healthy tissues. For prostate cancer, this tumor may be either local, locally advanced with extracapsular involvement, or extend into the pelvic lymph node chain. Automating essential parts of this process would allow for the rapid development of effective treatment …
