Scientific title	Dose EscaLation to Intraprostatic tumour Nodules in localisEd prostATE cancer: A phase II study examining the toxicity and feasibility of a dose escalated boost to a magnetic resonance imaging identified tumour nodule or nodules in localised prostate cancer
Study acronym	DELINEATE
Study hypothesis	Dose Escalation to Intra-prostatic Tumour Nodules in Localised Prostate Cancer To assess the toxicity and feasibility of a dose escalated intensity-modulated radiotherapy boost to tumour nodules within the prostate using anatomical and functional magnetic resonance (MR) imaging to identify tumour. The aim is to maintain current levels of late toxicity.
Ethics approval(s)	11/LO/0510
Condition	Topic: National Cancer Research Network; Subtopic: Prostate Cancer; Disease: Prostate
Intervention	Interventions as of 03/05/2017: 350 patients to be recruited and have MRI scans to diagnose intra-prostatic tumour nodules. Intra-prostatic tumour lesions will be treated with a radiotherapy boost. Radiotherapy boost: A dose escalated external beam radiotherapy boost to intraprostatic tumour nodules within the prostate gland; Follow Up Length: 60 month(s); Study Entry : Registration only Original interventions: 100 patients to be recruited and have MRI scans to diagnose intra-prostatic tumour nodules. 50% of patients expected to have lesions and so 50 patients to be treated with a radiotherapy boost Radiotherapy boost: A dose escalated external beam radiotherapy boost to intraprostatic tumour nodules within the prostate gland; Follow Up Length: 60 month(s); Study Entry : Registration only
Intervention type	Other
Primary outcome measure	Late rectal toxicity; Timepoint(s): 12 months
Secondary outcome measures	1. Acute genitourinary (Gu) and gastrointestinal (GI) toxicity; Timepoint(s): 18 weeks 2. Biochemical Recurrence; Timepoint(s): 24 months 3. Late GU and GI toxicity; Timepoint(s): 12 months and 24 months 4. Quality of Life Scores; Timepoint(s): 24 months
Overall study start date	13/07/2011
Overall study end date	31/12/2023
