A retrospective evaluation of inter-fraction motion in prostate cancer patients with involved nodes receiving prostate and pelvic ± para-aortic nodal irradiation.

Introduction: The inter-fraction motion of pelvic ± para-aortic (PA) nodal volumes in prostate cancer patients with involved nodes is yet to be quantified and the optimal IGRT strategy for these patients is currently unknown.

Methods: A single-centre retrospective evaluation was performed investigating inter-fraction motion in the prostate and involved nodal volumes of patients receiving pelvic ± PA nodal irradiation. Patients were selected for inclusion if they; were undergoing prostate + pelvic node +/- PA node radiation for prostate cancer with involved lymph nodes and had received daily online CBCT scans.

Influence of molecular imaging on patient selection for treatment intensification prior to salvage radiation therapy for prostate cancer: a post hoc analysis of the PROPS trial.

Background: The impact of molecular imaging (MI) on patient management after biochemical recurrence (BCR) following radical prostatectomy has been described in many studies. However, it is not known if MI-induced management changes are appropriate. This study aimed to determine if androgen deprivation therapy (ADT) management plan is improved by MI in patients who are candidates for salvage radiation therapy.

Comparative Effectiveness Analyses of Salvage Prostatectomy and Salvage Radiotherapy Outcomes Following Focal or Whole-Gland Ablative Therapy (High-Intensity Focused Ultrasound, Cryotherapy or Electroporation) for Localised Prostate Cancer.

Aims: Ablative therapy, such as focal therapy, cryotherapy or electroporation, aims to treat clinically significant prostate cancer with reduced treatment-related toxicity. Up to a third of patients may require further local salvage treatment after ablative therapy failure. Limited descriptive, but no comparative, evidence exists between different salvage treatment outcomes.

Contractile and Structural Properties of Detrusor from Children with Neurogenic Lower Urinary Tract Dysfunction.

Neurogenic lower urinary tract (NLUT) dysfunction in paediatric patients can arise after congenital or acquired conditions that affect bladder innervation. With some patients, urinary tract dysfunction remains and is more difficult to treat without understanding the pathophysiology. We measured in vitro detrusor smooth muscle function of samples from such bladders and any association with altered Wnt-signalling pathways that contribute to both foetal development and connective tissue deposition.
