Outcomes
Primary outcome [1] 0 0
Accumulated patient dose distributions will be determined via paired controls by comparing the measured treatment accuracy and dose with KIM and those that would have been delivered in the absence of KIM
Timepoint [1] 0 0
up to 36 months
Secondary outcome [1] 0 0
Patient treatment outcomes determined by assessing Biochemical-clinical failure (BCF)
Timepoint [1] 0 0
up to a maximum of 36 months.
Secondary outcome [2] 0 0
Patient treatment outcomes determined by assessing acute and late toxicity grade 3 or higher (using CTCAE version 4)
Timepoint [2] 0 0
Weekly during treatment, then two weeks, six weeks and 6 months post treatment
Secondary outcome [3] 0 0
Patient treatment outcomes determined by assessing patient-reported outcomes
Timepoint [3] 0 0
12 and 24 months after treatment
Secondary outcome [4] 0 0
The patient's perception of KIM will be quantified using an adapted SAT-RAR survey, an instrument that has previously been used to assess patient perceptions on technological innovations in radiotherapy and respiratory gating.
Timepoint [4] 0 0
up to 36 months
Secondary outcome [5] 0 0
Targeting accuracy through measuring the final geometric accuracy with and without the KIM gating procedure
Timepoint [5] 0 0
up to 36 months
Secondary outcome [6] 0 0
Radiation therapists feedback on KIM will be quantified using a survey which will obtain specific information about the impact of the KIM system and SPARK on education, patient workflow, clinical impact and user confidence
Timepoint [6] 0 0
up to 36 months

Summary
Brief summary
The SPARK trial is testing the use of Kilovoltage Intrafraction Monitoring in prostate cancer
patients being treated with Stereotactic Prostate Adaptive Radiotherapy. The researchers
expect this trial to result in better targeted prostate cancer patient outcomes with lower
toxicity. The potential application of Kilovoltage Intrafraction Monitoring to other tumour
sites will pave the way for additional trials with Australasian radiation oncology leading
the world.
