Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - WBRT
Treatment: Other - SART
Treatment: Other - DART

Active Comparator: WBRT - Standard dose whole bladder radiotherapy

Experimental: SART - Standard dose Adaptive tumour focused radiotherapy (SART)

Experimental: DART - Dose escalated Adaptive tumour boost radiotherapy (DART)


Treatment: Other: WBRT
One RT plan with whole bladder treated to standard dose.

Treatment: Other: SART
Three plans (small, medium & large) generated with the standard dose of RT focused on the tumour, sparing the normal bladder from full dose radiation. Pretreatment cone beam CTs will be used to select the best fitting of the three plans prior to treatment.

Treatment: Other: DART
Three plans (small, medium & large) generated with a higher dose than standard focused on the tumour and the remainder of the bladder treated to the same dose as in the SART group. Pretreatment cone beam CTs will be used to select the best fitting of the three plans prior to treatment.

Summary
Brief summary
Bladder cancer is the seventh most common cancer in the UK, with 10,399 new cases diagnosed
in 2011. In a quarter of these cases the cancer has infiltrated the muscular wall of the
bladder (muscle invasive) and is life threatening. This type of bladder cancer is usually
treated either with surgical removal of the bladder, or daily radiotherapy treatment (high
strength xrays which kill cells), given every day for 4 or 7 weeks. RAIDER will investigate
methods which have the potential to improve how well this radiotherapy works.

RAIDER is based on a study of novel radiotherapy techniques which was conducted at a single
UK NHS Trust. Bladder radiotherapy is normally delivered using a single plan throughout
treatment and treats the whole bladder with the same radiotherapy dose. In adaptive
radiotherapy the delivery plan is chosen from 3 possible plans. In cancer (tumour) focused
radiotherapy, the highest dose of the radiotherapy is aimed at the tumour within the bladder.

In RAIDER, 240 participants with muscle invasive bladder cancer will be in one of 3 treatment
groups:

1. standard whole bladder radiotherapy

2. standard dose tumour focused adaptive radiotherapy

3. dose escalated tumour boost adaptive radiotherapy

Participants will visit the hospital 4 weeks, 3, 6, 9, 12, 18 and 24 months after
radiotherapy and annually thereafter to check whether the cancer has returned and to receive
treatment for any symptoms they may be experiencing.

RAIDER aims to confirm in a multicentre setting that novel techniques allow a higher
radiotherapy dose than standard to be reliably targeted at the tumour within the bladder and
to check that the long term side effects of the treatment are acceptable. If this is the
case, results of RAIDER will be used to develop a study to establish whether dose escalated
radiotherapy is better at treating bladder cancer than standard dose.
