علماء بريطانيون يبدأون الاختبارات الجينية لأورام الأطفال. ويأمل العلماء البريطانيون أن تمنح الاختبارات الجينية المرضى الأصغر سنا علاجات أحدث وأكثر تخصيصا من شأنها أن تزيد من فرص بقائهم على قيد الحياة. ويحلل الاختبار الجديد 81 تغيرًا وراثيًا مختلفًا للسرطان.
Scientists say the test will lead to “a higher level of playing field” and accelerate children’s access to important new drug treatments. The test was performed at the Royal Marsden National Health System Hospital in London and will be tested on 400 children from all over the UK over the next two years.
The test has been implemented with genetic funding from the National Institutes of Health (NIHR) foundation and the السرطان. Institute. A charity called Christopher has provided more than £ 300,000 in funding to develop the test. The organization was founded by a couple whose children died of invasive أورام الدماغ في سن السادسة.
This is a real first step towards personalized في الإصابة بالسرطانات for children,” said Christopher’s parents, Karen and Kevin Capel. Christopher got a generic ورم. Hopefully, in the future, children will know exactly what type of tumor they have.” “We almost feel that the treatment for the child is not to kill the cancer, but to kill our child.”
“He used to be a healthy, happy, very athletic 4-year-old kid. But he became unable to speak or even eat on his own, and lost weight. “In the year he was diagnosed, he was unable to grow into a child of his age. We tried to keep him from other children.”
الأورام الخبيثة نادرة جدًا عند الأطفال ، ولا يوجد الكثير من المرضى التجارب السريرية for pharmaceutical companies will lack motivation. This means that children will miss the opportunity to receive targeted treatments for cancer cells without damaging healthy cells with innovative therapies.
Professor Louis Chesler, who is leading the genetic testing research, said: “Children often don’t have equal access to the most advanced and potentially beneficial cancer treatments.” “The cost of developing gene-targeted drugs is very high. They tend to Test it on adults first so that more people can get treatment and the results can be seen faster. ”
"هذا الاختبار هو تقدم مذهل لأنه سيحدد بوضوح جميع التغيرات الجينية في الورم." "يمنح اختبار الجينات الأطباء أداة قوية للغاية - تساعدهم في اختيار الدواء المناسب لأطفالهم وبذل قصارى جهدهم. قد يكون من الممكن تحديد فعالية هذه الأدوية بسرعة. "
Children’s tumors are usually genetically simpler than adult tumors, so eventually these drugs may be more effective in children.” The goal of الاختبارات الجينية is to give scientists and doctors detailed genes for childhood tumors within a few weeks of diagnosis. information.
Genetic testing gives doctors strong evidence to use العلاجات المستهدفة for younger patients, potentially preventing these patients from experiencing the side effects associated with traditional chemotherapy and radiation therapy.
Jack Daly, 14, from Wokingham, was diagnosed with a brain tumor when he was 7 and is now a brain tumor الناجي. Radiotherapy helped save his life, but left him with sequelae. “My athletic ability is not very good,” Jack said. “I have to get someone to help me dress and undress at school.” “My balance is not good-I am awkward and often fall. I worked hard at school, where I found friendship.” Jack and his mother, Helen, use their donations to make ends meet in Capels-hoping that الاختبارات الجينية will make a huge difference in the quality of life of future children.
"لا يرى الناس المشكلة حقًا لأن جاك تعافى من السرطان. لا يحتاج أن يكون على كرسي متحرك. قالت هيلين "ليس عليه أن يرتدي ضمادة".
"إذا رأيت جاك من قبل ، فهو يبدو مثل صبي مراهق عادي. ولكن ما لا تراه هو تلف أنسجة المخ الناجم عن العلاج ".
