Paediatric Cancers of the Central Nervous System

Debate between Ian Murray and Chris Elmore

Monday 22nd October 2018 Commons Chamber

[Chris Elmore]

I agree entirely with the hon. Gentleman. I hope my speech will go some way to highlighting that more work is needed, and to paying tribute to parents and families who have lost children through this horrendous condition.

Cian was first diagnosed with an atypical teratoid/rhabdoid tumour in 2015, when he was four years old. This type of tumour, often called an AT/RT, is a very rare and rapidly growing tumour of the central nervous system. Cian’s primary tumour was found on his spine, with seeds of the cancer also found in his brain. In the majority of cases, AT/RT is associated with a specific genetic mutation, INI1, which can occur spontaneously or be inherited. However, genetic testing in Cian’s instance did not indicate that he had this specific mutation. Cian’s tumour was located on his spine. AT/RTs are generally located anywhere in the brain, but are most commonly found in the cerebellum—the base of the brain—and in the brain stem, which is the part of the brain that controls basic body functions. The fact that Cian’s tumour bucked this trend made a difficult medical situation even more complex. AT/RT was previously thought to have been a type of medulloblastoma. However, it is now known that this is a totally different type of cancer and cannot therefore be treated via the same methods.

Mercifully, childhood cancer is rare in itself. The majority of children who are sadly subjected to this disease are diagnosed with a form of leukaemia. Brain tumours are much more rare, and AT/RTs make up only between 1% and 2% of these cases. I hope this illustrates just how tragic it was that Cian contracted not just cancer, but a cancer of the rarest of forms. This, however, is exactly why we have to do something. We have to do something to remember Cian and ensure that his legacy is that other families may be prevented from suffering a similar fate.

I congratulate my hon. Friend on his wonderful speech and pay tribute to Cian’s family for all they have done on this issue. Will he join me in paying tribute also to Cancer Research UK, which in the past 12 months has tripled its funding for brain cancer research, understanding that it has been under-researched up to now? Should we not be encouraging the Government and working with them to do all they can to ensure that research into these key cancers continues?

[Chris Elmore]

I agree entirely. I am sure the Minister will set out the extra work the Government here and the Administrations in Scotland, Cardiff and Belfast are doing.

The very fact that these cancers are rare often makes it difficult to get a research cohort together, but we cannot allow that to be a barrier to finding new treatments and even cures for such illnesses. The treatments currently available for childhood cancers in the brain or spine tumours range from neurosurgery to radiotherapy, chemotherapy and steroids, and finally proton beam therapy. The course of treatment is tailored to the individual case, with patients typically undergoing multiple treatments. Sadly, AT/RT patients do not typically have good survival rates, and outcomes are poorer if a child has signs of tumour spread at diagnosis. We cannot accurately predict the outcome for any individual child who has developed such a tumour, but children diagnosed who are less than 12 months old are less likely to be able to fight the disease.

It will come as no surprise to hon. Members when I say that the key to fighting this disease in the long term lies in medical research. There are many competing priorities in medical research, with many historic frontiers yet to be conquered, but we must ensure that all forms of illness that cause pain and suffering receive the attention and the willingness to tackle them they deserve. I welcome the announcement from the Department of Health and Social Care earlier this year that the UK will invest £20 million in brain tumour research over the next five years. In addition, Cancer Research UK is investing £25 million to support that work. Will the Minister say what percentage of that funding will be used specifically for research into paediatric cancers?
