Surface Guided Radio Therapy (SGRT)

I am about halfway through my (fairly) run of the mill prostate treatment. 3 monthly Prostap and RT (20 sessions) last Oct/Nov. I had one hospital (in effect) refuse to give me RT as I had two replacement hips - I was then referred to another hospital - where my hips seemed to pose no problem whatsoever. (My diagnosing hospital has no radio therapy equipment) Not only did my metal hips seem to be ignored - the tattoos and the dreaded daily enemas were too ! As I had a 90+ mile train/bus round trip every day the enemas could have posed quite a problem !!  Just drink 500ml of water - and I was ready to go  (Literally !).........

The hospital that did my RT has 6 Linacs, all fitted with SGRT. I have been following many of the threads on this site and I cannot remember seeing any reference to SGRT being used elsewhere. Just lots of tattoos and enemas.  I may just be extremely lucky - but my HT produced minimal side effects. The "blurb" on SGRT says it is much more accurately targeted than the 3 dot method. Equally, the RT has produced nothing in the way of attributable side effects - coincidence ? - or due to the machine ??

Just out of curiosity, I would be interested to know if anyone else had SGRT equipment used for their treatment and what their experience was. 

  • Hi Moonrakerz

    I saw that you  hadn't had an answer so thought I would reply, SGRT is fairly new I think although people were talking about it in 2017 when I had my RT,

    Probably unlikely that anyone on here will have had it although u never know. I have read good things about it and looks like good new for you by the sound of it

    Best wishes

  • Hello Steve,

    thanks for your reply, as you say, SGRT does sound a good step forward.

    One thing I have found since my diagnosis is how very difficult it is to find out exactly what capabilities various treatment centres can offer. I now have ten times as many questions about RT as I have already asked !

    I have spent some time picking my way through many NHS hospital websites to see who has got what. There are 65 cancer treatment centres in the UK, of these I can find references to 18 of these having SGRT fitted Linacs. The first appears to have been installed in 2015. What really surprised me is that SGRT equipment is not currently funded by the NHS - "because it is not a core function for effective treatment". That is: it is not a new treatment, just an improvement to existing treatment. 

    (Many of the websites are not dated, so the above figures may not be 100% accurate - but do give an idea)

    It also appears that SGRT is already being overtaken by yet another new development, an MR Linac - which combines an MRI scanner and a Linac in one piece of equipment. This gives even greater accuracy of placing the radiation beam correctly on the tumour and avoiding the parts that do not need radiation.

    Costs:  I have seen appeals for donations for SGRT equipment - this seems to suggest costs are about £200,000 per set to add to a fairly modern Linac. I also found one hospital stating that its (single !) brand new MR Linac cost £3.5M !!  Doesn't say who paid for it.........

    If anyone does come across SGRT in their treatment I would still like to hear their thoughts. I would certainly suggest that those about to have RT enquire as to what is available in their area.

  • Just finished my radiotherapy and to be honest I don't know really what I had (terrible I no lol ) but there are 3 machines and the signs to them all said linac this was at Peterborough and I have to say my care was fantastic 

  • Can't see any reference to SGRT at Peterborough on the web - but that might depend on how up to date the site is.  If there is SGRT there will be 3 projector/camera housings on the ceiling pointing down at the patient on the table.

    Something like these..............

  • If it helps I had IMRT and  IGRT together which was one of the latest at  the time, this included the fiducial gold markers to help with targeting.

    No problems at the time and no problems 8 years later

  •  My hospital in  Inverness uses SGRT, and had been just been given over £700,000 to upgrade the software  on their two Varian machines early 2024, they had started to install/work with it early that summer, my treatment ended in early December 2024. 

  • Hi  

    My husband had targetted RT on a MRIdian Linac two and a half years ago . He had full pelvic RT plus lymph nodes & his lower torso (ribs) 20 sessions, I can’t remember SG/SArt ?? To be honest it took him a while to recover (fitness) as it was so extensive, but recover he did. Very good results so far. There is an expectation with him that as the years go on he could have problems caused by the internal scars shrinking and pulling on areas like the urethra, but. Nothing as yet. The linac was and is an excellent machine for accurate targeting I believe.

  • Thanks for that - Inverness did not come up on my searches !
