Nowotwory mózgu u dzieci
Diagnostyka i diagnoza
Nowotwory mózgu u dzieci stanowią około 25% wszystkich nowotworów pediatrycznych, z roczną zachorowalnością w USA na poziomie 3500-4200 przypadków. Diagnostyka wymaga wielodyscyplinarnego podejścia w wyspecjalizowanych ośrodkach, co przekłada się na 20-40% wyższe wskaźniki przeżycia. Obraz kliniczny jest zróżnicowany i często niespecyficzny, obejmując m.in. bóle głowy (szczególnie poranne), wymioty, zaburzenia równowagi, deficyty neurologiczne oraz objawy wzrokowe. Podstawą diagnostyki jest szczegółowe badanie neurologiczne i okulistyczne, w tym ocena dna oka pod kątem obrzęku tarczy nerwu wzrokowego. MRI z kontrastem (gadolinium) pozostaje złotym standardem obrazowania, uzupełnionym o techniki takie jak fMRI, DWI, MRS i perfuzja MR, zgodnie z wytycznymi RAPNO. Tomografia komputerowa jest stosowana głównie w sytuacjach nagłych, ze względu na ekspozycję na promieniowanie jonizujące. Biopsja stereotaktyczna lub otwarta pozostaje kluczowa dla potwierdzenia histopatologicznego i molekularnego rozpoznania, niezbędnego do planowania leczenia.

Diagnostyka nowotworów mózgu u dzieci – wprowadzenie
Nowotwory mózgu u dzieci stanowią drugą najczęstszą grupę nowotworów dziecięcych (po białaczkach), odpowiadając za około 25% wszystkich dziecięcych przypadków onkologicznych. Rocznie w Stanach Zjednoczonych diagnozuje się około 3500-4200 nowych przypadków nowotworów mózgu u dzieci i młodzieży.12 Wczesna i precyzyjna diagnostyka jest kluczowa dla rokowania i skutecznego leczenia. Nowotwory mózgu u dzieci różnią się istotnie od tych występujących u dorosłych pod względem typu, lokalizacji, biologii molekularnej i odpowiedzi na leczenie, co wymaga specjalistycznego podejścia pediatrycznego.34
Proces diagnostyczny nowotworów mózgu u dzieci powinien być prowadzony przez specjalistyczny wielodyscyplinarny zespół w ośrodkach wyspecjalizowanych w onkologii dziecięcej. Amerykańska Akademia Pediatrii i Narodowy Instytut Raka zalecają, aby dzieci otrzymywały diagnozę i leczenie nowotworów w jednym z ponad 200 ośrodków medycznych w USA specjalizujących się w nowotworach pediatrycznych, ponieważ badania wskazują na 20-40% wyższe wskaźniki przeżycia w takich placówkach.5
Objawy kliniczne i badanie neurologiczne
Objawy nowotworów mózgu u dzieci są zróżnicowane i zależą od wieku dziecka, lokalizacji guza, jego wielkości oraz tempa wzrostu. Często są niespecyficzne, co może prowadzić do opóźnień diagnostycznych. Nowotwory mózgu u dzieci są często początkowo błędnie diagnozowane jako bardziej powszechne schorzenia pediatryczne, takie jak migrena, zaburzenia żołądkowo-jelitowe lub problemy psychologiczne i behawioralne.6
Typowe objawy nowotworów mózgu u dzieci
- Bóle głowy, szczególnie po przebudzeniu rano
- Wymioty, zwłaszcza poranne, niezwiązane z infekcją
- Zaburzenia równowagi i chodu
- Problemy ze wzrokiem (podwójne widzenie, zez)
- Drgawki lub napady padaczkowe
- Zmiany zachowania lub osobowości
- Osłabienie mięśni lub porażenie jednostronne
- Opóźnienie lub regres rozwojowy
- U niemowląt: powiększenie obwodu głowy, uwypuklenie ciemiączka
Badanie neurologiczne jest pierwszym krokiem w diagnostyce nowotworu mózgu u dziecka. Lekarz przeprowadza kompleksowe badanie oceniające:910
- Odruchy neurologiczne
- Siłę mięśniową
- Ruchy gałek ocznych i ust
- Koordynację ruchową
- Równowagę
- Czucie
- Stan świadomości i czujność
Podczas badania neurologicznego lekarz może również ocenić dno oka w poszukiwaniu obrzęku tarczy nerwu wzrokowego, co może wskazywać na podwyższone ciśnienie wewnątrzczaszkowe. Okuliści mogą odegrać istotną rolę w diagnostyce guzów mózgu u dzieci, gdyż podczas rutynowego badania wzroku mogą wykryć zmiany na dnie oka sugerujące zwiększone ciśnienie śródczaszkowe.13
Diagnostyka obrazowa
Badania obrazowe stanowią kluczowy element w diagnozowaniu nowotworów mózgu u dzieci. Pozwalają na wykrycie guza, określenie jego lokalizacji, wielkości oraz charakterystyki. Współczesne techniki obrazowania umożliwiają również ocenę wpływu guza na otaczające struktury mózgu.14
Rezonans magnetyczny (MRI)
MRI jest uważany za złoty standard w diagnostyce obrazowej nowotworów mózgu u dzieci. Zapewnia szczegółowe obrazy struktur mózgu bez narażenia dziecka na promieniowanie jonizujące.15
- Standardowy protokół MRI – obejmuje sekwencje T1, T2, FLAIR oraz obrazowanie z podaniem środka kontrastowego (gadolinu), który pomaga uwidocznić granice guza i jego unaczynienie
- MRI czynnościowy (fMRI) – pomaga określić lokalizację obszarów funkcjonalnych mózgu względem guza, co jest kluczowe w planowaniu leczenia chirurgicznego
- Obrazowanie dyfuzyjne (DWI) – dostarcza informacji o mikrostrukturze tkanki i gęstości komórkowej guza
- Spektroskopia MR (MRS) – umożliwia analizę metabolitów w tkance guza, co może pomóc w różnicowaniu typów nowotworów
- Obrazowanie perfuzji MR – ocenia unaczynienie guza
Najnowsze wytyczne Response Assessment in Pediatric Neuro-Oncology (RAPNO) określają minimalne niezbędne sekwencje MRI dla różnych typów nowotworów mózgu u dzieci.18 Obrazowanie powinno obejmować zarówno mózg, jak i rdzeń kręgowy, aby ocenić potencjalne rozsiewy guza w obrębie ośrodkowego układu nerwowego.19
Tomografia komputerowa (CT)
Tomografia komputerowa jest często pierwszym badaniem obrazowym wykonywanym u dzieci z podejrzeniem guza mózgu, szczególnie w sytuacjach nagłych. Jest szybka i szeroko dostępna, ale wiąże się z ekspozycją na promieniowanie jonizujące.2021
- Pozwala na szybką ocenę obecności guza, krwawienia lub obrzęku mózgu
- Jest przydatna w ocenie zwapnień w obrębie guza, co może być charakterystyczne dla niektórych typów nowotworów
- W połączeniu z kontrastem (angiografia CT) może dostarczyć informacji o unaczynieniu guza
Ze względu na narażenie na promieniowanie, CT nie jest zalecana jako badanie kontrolne i, jeśli to możliwe, powinna być zastępowana przez MRI w dalszej diagnostyce i monitorowaniu.24
Inne techniki obrazowania
W zależności od specyfiki przypadku, mogą być stosowane również inne metody obrazowania:2526
- Pozytonowa tomografia emisyjna (PET) – wykorzystuje radioaktywne znaczniki do oceny metabolizmu tkanek; może pomóc w różnicowaniu między aktywnym guzem a tkanką bliznowatą lub martwiczą
- Angiografia – używa kontrastu i promieniowania rentgenowskiego do obrazowania naczyń krwionośnych w mózgu; pomocna w ocenie unaczynienia guza przed operacją
- Badania radioizotopowe – wykorzystują radioaktywne znaczniki do identyfikacji specyficznych typów komórek nowotworowych
Warto zaznaczyć, że zaawansowane techniki obrazowania, takie jak obrazowanie dyfuzyjne w połączeniu z algorytmami uczenia maszynowego (AI), mogą zwiększyć dokładność diagnostyczną i pomóc w nieinwazyjnej klasyfikacji typów nowotworów mózgu u dzieci.2829
Biopsja i diagnostyka histopatologiczna
Pomimo postępów w diagnostyce obrazowej, biopsja pozostaje złotym standardem w diagnostyce nowotworów mózgu u dzieci. Analiza materiału tkankowego pozwala na dokładne określenie typu histologicznego guza, jego złośliwości oraz cech molekularnych, co jest niezbędne do zaplanowania optymalnego leczenia.30
Metody pobrania materiału
- Biopsja stereotaktyczna – minimalnie inwazyjna procedura, podczas której cienka igła jest wprowadzana do mózgu przez mały otwór w czaszce pod kontrolą obrazowania (CT lub MRI) w celu pobrania próbki tkanki
- Biopsja otwarta – wykonywana podczas kraniotomii, umożliwia pobranie większej próbki lub całkowite usunięcie guza
- Biopsja endoskopowa – wykorzystuje endoskop wprowadzany przez małe nacięcie w czaszce, szczególnie przydatna w przypadku guzów wewnątrzkomorowych
W przypadku niektórych typów guzów, ze względu na ich lokalizację (np. pień mózgu), wykonanie biopsji może być ryzykowne. W takich sytuacjach rozpoznanie może być oparte na charakterystycznym obrazie radiologicznym i objawach klinicznych.3334
Badania histopatologiczne i molekularne
Współczesna diagnostyka nowotworów mózgu u dzieci opiera się na zintegrowanym podejściu łączącym klasyczną histopatologię z badaniami molekularnymi:3536
- Klasyczna histopatologia – ocena morfologii komórek nowotworowych, ich układu i cech atypii
- Badania immunohistochemiczne – identyfikacja specyficznych białek komórkowych za pomocą przeciwciał
- Badania cytogenetyczne – analiza aberracji chromosomowych
- Profilowanie metylacji DNA – metoda diagnostyczna znacznie zwiększająca dokładność rozpoznania w porównaniu ze standardowymi metodami
- Sekwencjonowanie nowej generacji – identyfikacja mutacji genowych i innych zmian genetycznych, które mogą mieć znaczenie diagnostyczne, prognostyczne i terapeutyczne
- Specjalistyczne testy molekularne – takie jak MSK-IMPACT i Archer FusionPlex, które pozwalają na identyfikację specyficznych zmian genetycznych
Klasyfikacja histologiczna nowotworów ośrodkowego układu nerwowego opiera się na kryteriach Światowej Organizacji Zdrowia (WHO), która wprowadza zintegrowaną diagnostykę łączącą cechy histologiczne z profilem molekularnym guza. Guzy klasyfikowane są w skali od I do IV, gdzie stopień I oznacza nowotwór wolno rosnący o niskiej złośliwości, a stopień IV – nowotwór szybko rosnący o wysokiej złośliwości.3940
Badania uzupełniające
W diagnostyce nowotworów mózgu u dzieci stosuje się również szereg badań uzupełniających, które pomagają w ocenie zaawansowania choroby i planowaniu leczenia:4142
Nakłucie lędźwiowe i badanie płynu mózgowo-rdzeniowego
Nakłucie lędźwiowe (punkcja lędźwiowa) to procedura polegająca na pobraniu próbki płynu mózgowo-rdzeniowego (PMR) do badań. Jest to szczególnie ważne w przypadku niektórych typów nowotworów, takich jak rdzeniak (medulloblastoma), które mają tendencję do rozsiewu drogą PMR.4344
- Badanie cytologiczne PMR – ocena obecności komórek nowotworowych w płynie mózgowo-rdzeniowym
- Badanie biochemiczne PMR – ocena stężenia białka, glukozy i innych parametrów
- Badania molekularne PMR – poszukiwanie biomarkerów nowotworowych
Badania laboratoryjne
Badania krwi i inne testy laboratoryjne mogą dostarczyć informacji o ogólnym stanie zdrowia dziecka oraz potencjalnych powikłaniach związanych z guzem:46
- Morfologia krwi – ocena stanu układu krwiotwórczego
- Badania biochemiczne – ocena funkcji wątroby, nerek i innych narządów
- Markery nowotworowe – niektóre nowotwory, zwłaszcza guzy zarodkowe, mogą wydzielać specyficzne białka wykrywalne we krwi
- Badanie szpiku kostnego – w niektórych przypadkach, aby wykluczyć rozsiew nowotworu poza układ nerwowy
Badania okulistyczne
Kompleksowe badanie okulistyczne może dostarczyć cennych informacji diagnostycznych:49
- Badanie dna oka – ocena tarczy nerwu wzrokowego pod kątem obrzęku (papilledema), co może wskazywać na podwyższone ciśnienie śródczaszkowe
- Ocena pola widzenia – identyfikacja ubytków pola widzenia sugerujących ucisk na drogi wzrokowe
- Badanie ruchów gałek ocznych – wykrywanie niedowładów mięśni zewnątrzgałkowych sugerujących uszkodzenie nerwów czaszkowych
Nowoczesne podejście do diagnostyki
Medycyna precyzyjna i diagnostyka molekularna
Współczesna diagnostyka nowotworów mózgu u dzieci zmierza w kierunku medycyny precyzyjnej, która charakteryzuje genetyczne i molekularne nieprawidłowości w każdym konkretnym guzie mózgu. Podejście to pozwala na bardziej zindywidualizowane planowanie leczenia i lepsze przewidywanie odpowiedzi na terapię.51
- Kompleksowe profilowanie genetyczne – obejmujące badania w kierunku mutowanych genów, nieprawidłowo złożonych chromosomów oraz poszukiwanie nadmiaru lub braku kopii genów
- Systemy cyfrowego barcodingu molekularnego – takie jak NanoString Digital Molecular Barcoding System, które pozwalają na analizę unikalnych cech molekularnych guza u dziecka
- Biomarkery prognostyczne i predykcyjne – identyfikacja markerów biologicznych związanych z rokowaniem i odpowiedzią na leczenie
Te zaawansowane badania diagnostyczne umożliwiają dokładniejszą klasyfikację nowotworów mózgu u dzieci, co przekłada się na optymalizację strategii leczenia.54
Zastosowanie sztucznej inteligencji w diagnostyce
Sztuczna inteligencja (AI) i uczenie maszynowe są coraz częściej wykorzystywane w diagnostyce nowotworów mózgu u dzieci, oferując nowe możliwości w analizie obrazów i danych molekularnych:5556
- Automatyczna segmentacja i kwantyfikacja cech guzów w obrazach MRI i CT
- Klasyfikacja typów nowotworów na podstawie cech radiomicznych
- Prognozowanie przebiegu choroby i odpowiedzi na leczenie
- Integracja danych obrazowych, klinicznych i molekularnych w celu poprawy dokładności diagnostycznej
Badania wskazują, że połączenie zaawansowanych technik obrazowania, takich jak obrazowanie dyfuzyjne i perfuzyjne, z algorytmami uczenia maszynowego może istotnie poprawić dokładność nieinwazyjnej diagnostyki nowotworów mózgu u dzieci.59
Najnowsze badania sugerują, że zastosowanie MRI w połączeniu z AI może znacząco skrócić czas diagnozy w przypadku nowotworów mózgu u dzieci. W badaniu dotyczącym rdzeniaka (medulloblastoma) zidentyfikowano charakterystyczne profile metaboliczne dla różnych podgrup tego nowotworu, co może umożliwić szybszą diagnozę bez konieczności wykonywania inwazyjnej biopsji.60
Zintegrowana diagnoza i wielodyscyplinarne podejście
Diagnostyka nowotworów mózgu u dzieci wymaga współpracy wielu specjalistów. Zintegrowane podejście diagnostyczne stało się centralnym elementem klasyfikacji WHO nowotworów ośrodkowego układu nerwowego.61
Zespół wielodyscyplinarny
W skład zespołu zaangażowanego w diagnostykę nowotworów mózgu u dzieci wchodzą:6263
- Neurochirurdzy dziecięcy – odpowiedzialni za procedury biopsyjne i leczenie operacyjne
- Neuroradiolodzy – specjalizujący się w interpretacji obrazów diagnostycznych mózgu
- Neuropatolodzy – analizujący materiał tkankowy z biopsji
- Neuronokolodzy dziecięcy – koordynujący proces diagnostyczny i planujący leczenie
- Genetycy i specjaliści biologii molekularnej – wykonujący i interpretujący badania molekularne
- Radioterapeuci – planujący ewentualną radioterapię
- Neuropsycholodzy – oceniający funkcje poznawcze przed i po leczeniu
Złożone przypadki nowotworów mózgu u dzieci są omawiane na spotkaniach wielodyscyplinarnych zespołów, gdzie analizowane są wszystkie aspekty przypadku, w tym wyniki badań patologicznych tkanki guza oraz podejścia do leczenia.65
Zintegrowana diagnoza
Zintegrowana diagnoza nowotworów mózgu u dzieci uwzględnia:66
- Typ histologiczny guza – określony na podstawie badania mikroskopowego
- Stopień złośliwości – wskazujący na agresywność nowotworu i tempo jego wzrostu
- Profil molekularny – obejmujący mutacje genowe, aberracje chromosomowe i inne zmiany genetyczne
- Lokalizacja guza – różne typy nowotworów mają predylekcję do określonych lokalizacji w mózgu
- Dane kliniczne – wiek dziecka, objawy, wywiad
- Wyniki badań obrazowych – cechy radiologiczne guza
Ta kompleksowa ocena prowadzi do ustalenia precyzyjnej diagnozy, która jest podstawą do zaplanowania optymalnego leczenia.68
Diagnostyka szczególnych typów nowotworów
Niektóre nowotwory mózgu u dzieci wymagają specyficznego podejścia diagnostycznego ze względu na swoje unikalne cechy kliniczne i biologiczne.69
Glejak mostu (DIPG)
Rozlany glejak pnia mózgu (Diffuse Intrinsic Pontine Glioma, DIPG) jest jednym z najbardziej agresywnych nowotworów mózgu u dzieci, z bardzo złym rokowaniem.70
- Diagnoza opiera się głównie na charakterystycznym obrazie MRI (rozlany naciek mostu) oraz typowych objawach klinicznych (porażenie nerwów czaszkowych, zaburzenia równowagi, trudności w połykaniu)
- W większości przypadków nie wykonuje się biopsji ze względu na ryzyko powikłań związanych z lokalizacją guza
- Standardem postępowania jest rozpoznanie oparte na cechach radiologicznych i klinicznych, co jest uważane za wystarczające do rozpoczęcia leczenia empirycznego
Glejak nerwu wzrokowego
Glejaki nerwu wzrokowego (Optic Pathway Glioma, OPG) często występują u dzieci z nerwiakowłókniakowatością typu 1 (NF1).73
- Diagnoza opiera się na patognomonicznych cechach w badaniu MRI, w połączeniu z rozpoznaniem NF1 i widocznymi zmianami w badaniu okulistycznym
- Biopsja chirurgiczna ma zwykle ograniczone znaczenie w diagnostyce OPG u dzieci z NF1
- Biopsja może być wskazana w przypadku podejrzenia transformacji złośliwej lub agresywnego wzrostu guza
Guzy związane ze stwardnieniem guzkowatym
U pacjentów ze stwardnieniem guzkowatym (Tuberous Sclerosis, TS) często występują podwyściółkowe guzy olbrzymiokomórkowe (Subependymal Giant Cell Astrocytoma, SEGA).76
- Diagnoza może być postawiona na podstawie klinicznego/genetycznego rozpoznania TS i typowej lokalizacji guza bez konieczności wykonywania biopsji
- Charakterystyczne cechy w badaniu MRI w połączeniu z rozpoznaniem TS są zazwyczaj wystarczające do postawienia diagnozy
Wyzwania i perspektywy w diagnostyce
Diagnostyka nowotworów mózgu u dzieci stoi przed wieloma wyzwaniami, ale jednocześnie otwierają się nowe perspektywy związane z postępem technologicznym i naukowym.79
Wyzwania diagnostyczne
- Opóźnienia diagnostyczne – pomimo postępu w technikach obrazowania, czas od wystąpienia objawów do diagnozy pozostaje stosunkowo długi, co może wpływać negatywnie na rokowanie
- Ograniczenia w dostępie do zaawansowanych technik diagnostycznych – szczególnie w regionach o ograniczonych zasobach
- Trudności w interpretacji wyników badań molekularnych – ze względu na rzadkość niektórych zmian genetycznych i ograniczoną wiedzę na temat ich znaczenia klinicznego
- Ryzyko związane z procedurami inwazyjnymi – biopsja niektórych guzów, zwłaszcza zlokalizowanych w krytycznych obszarach mózgu, może wiązać się z istotnym ryzykiem powikłań
Perspektywy rozwoju
- Nieinwazyjna diagnostyka molekularna – rozwój technik umożliwiających analizę DNA nowotworowego krążącego we krwi (tzw. liquid biopsy)
- Zaawansowane techniki obrazowania – rozwój nowych sekwencji MRI, obrazowania metabolicznego i technik opartych na AI
- Personalizacja diagnostyki – dostosowanie protokołów diagnostycznych do indywidualnych cech pacjenta i guza
- Udoskonalenie klasyfikacji nowotworów – integracja danych klinicznych, radiologicznych, histopatologicznych i molekularnych w celu stworzenia bardziej precyzyjnych i klinicznie użytecznych systemów klasyfikacji
Najnowsze badania sugerują, że zastosowanie technik obrazowania opartych na AI może w przyszłości pozwolić na znaczne skrócenie czasu diagnostyki z obecnych 3-4 tygodni do kilku dni, co może mieć istotny wpływ na wyniki leczenia.83
Znaczenie wczesnej i precyzyjnej diagnostyki
Wczesna i precyzyjna diagnostyka nowotworów mózgu u dzieci ma kluczowe znaczenie dla optymalizacji wyników leczenia i minimalizacji długoterminowych powikłań.84
- Poprawa przeżywalności – wczesne wykrycie guza umożliwia szybsze rozpoczęcie leczenia, co może poprawić wskaźniki przeżycia
- Optymalizacja leczenia – precyzyjna diagnoza pozwala na dobór najbardziej odpowiedniej metody leczenia, uwzględniającej specyfikę guza
- Redukcja powikłań neuropsychologicznych – wczesna interwencja może zmniejszyć ryzyko długoterminowych deficytów poznawczych i rozwojowych
- Lepsze planowanie leczenia chirurgicznego – dokładna charakterystyka guza przed operacją umożliwia optymalne zaplanowanie zabiegu
- Identyfikacja pacjentów kwalifikujących się do badań klinicznych – precyzyjna charakterystyka molekularna guza może pomóc w identyfikacji pacjentów, którzy mogliby odnieść korzyść z innowacyjnych terapii w ramach badań klinicznych
Pięcioletnie względne wskaźniki przeżycia dla wszystkich pierwotnych nowotworów mózgu u dzieci wynoszą około 83%, a dla nowotworów złośliwych około 75,6%. Wskaźniki te mogą się różnić w zależności od typu guza i jego lokalizacji.87
Podsumowanie schematu diagnostycznego
Optymalna ścieżka diagnostyczna w przypadku podejrzenia nowotworu mózgu u dziecka obejmuje:8889
- Wstępna ocena kliniczna
- Szczegółowy wywiad medyczny i badanie przedmiotowe
- Badanie neurologiczne oceniające funkcje ośrodkowego układu nerwowego
- Badanie okulistyczne z oceną dna oka
- Diagnostyka obrazowa
- MRI mózgu i rdzenia kręgowego z kontrastem – badanie pierwszego wyboru
- CT głowy – w sytuacjach nagłych lub gdy MRI nie jest dostępny

- #1 Pediatric Brain Tumorshttps://braintumor.org/brain-tumors/about-brain-tumors/pediatric-brain-tumors/
More than 5,200 children and adolescents (ages 0-19) will be diagnosed with a primary brain tumor in the U.S. this year alone. Whether benign (noncancerous) or malignant (cancerous), brain tumors can have lasting and life-altering physical, cognitive, social, and emotional impacts on a patients life. […] Pediatric brain tumors can differ from those in adults in terms of the specific types of tumors that are most common. […] There can be differences in the genetic and molecular characteristics of pediatric and adult brain tumors. Certain genetic mutations and markers may be more common in pediatric cases, influencing treatment options and responses. Treatment strategies for pediatric and adult brain tumors can vary due to differences in tumor biology, growth patterns, and the developing brain in children.
- #2 Brain Tumor Factshttps://braintumor.org/brain-tumors/about-brain-tumors/brain-tumor-facts/
Approximately 3,920 new cases of primary childhood brain tumors are expected to be diagnosed in 2023. […] Brain tumors are the most commonly diagnosed solid cancer in children ages 0-14 years, as well as the leading cause of childhood cancer-related death. […] The five-year relative survival rate for all primary childhood brain tumors is 83.1%. […] For primary malignant childhood tumors, the five-year relative survival rate is 75.6%. […] The five-year relative survival rate for all primary pediatric brain tumors (0-19) is 83.9%. […] For malignant tumors, the five-year relative survival rate is 75.6%. […] Pediatric brain tumors are the leading cause of cancer-related death among children and adolescents ages 0-19 years. […] AT/RT and high-grade gliomas have the lowest relative survival after diagnosis for patients 0-19 years with a brain tumor. […] Relative survival rates generally improve with increasing age at diagnosis in this population group, with poorest survival in those less than a year old at diagnosis.
- #3 MRI-based diagnosis and treatment of pediatric brain tumors: is tissue sample always needed?https://pmc.ncbi.nlm.nih.gov/articles/PMC8084800/
Traditional management of newly diagnosed pediatric brain tumors (PBTs) consists of cranial imaging, typically magnetic resonance imaging (MRI), and is frequently followed by tissue diagnosis, through either surgical biopsy or tumor resection. […] Current management of newly diagnosed pediatric brain tumors (PBTs) consists of central nervous system (CNS) imaging, typically magnetic resonance imaging (MRI), followed by tissue diagnosis, through either surgical biopsy or tumor resection. […] The aim of this review is to explore the role of MRI-based diagnosis and treatment of these PBTs in the current oncological era. […] Typical MRI findings and indications for surgical biopsy of these lesions are described. […] The standard treatment for DIPG, to date, remains focal radiation therapy to the pons; no surgical or chemotherapeutic strategy has shown improvement in overall survival.
- #4 Brain Tumors – AANShttps://www.aans.org/patients/conditions-treatments/brain-tumors/
Brain tumors in children typically come from different tissues than those affecting adults. Treatments that are fairly well-tolerated by the adult brain (such as radiation therapy) may prevent normal development of a child’s brain, especially in children younger than age five. […] According to the Pediatric Brain Tumor Foundation, approximately 4,200 children are diagnosed with a brain tumor in the U.S. Seventy-two percent of children diagnosed with a brain tumor are younger than age 15. Most of these brain tumors grow in the posterior fossa (or back) of the brain. Children often present with hydrocephalus (fluid build up in the brain) or the face or body not working properly. […] Some types of brain tumors are more common in children than in adults. The most common types of pediatric tumors are medulloblastomas, low-grade astrocytomas (pilocytic), ependymomas, craniopharyngiomas and brainstem gliomas.
- #5 Brain Tumors in Children – Stanford Medicine Children’s Healthhttps://www.stanfordchildrens.org/en/topic/default?id=brain-tumors-in-children-90-P02745
Brain tumors can occur at any age. Brain tumors that occur in infants and children are very different from adult brain tumors, both in terms of the type of cells and the responsiveness to treatment. […] In addition, both the American Academy of Pediatrics and the National Cancer Institute recommend that children receive cancer diagnosis and treatment at one of the more than 200 medical centers in the U.S. that specialize in pediatric cancers. The organizations cite research studies that show 20% to 40% higher survival rates when children receive care in such specialized centers. […] In addition to a complete medical history and physical examination of your child, examination procedures for a brain tumor may include: […] Examination of a brain tumor depends mostly on the types of cells in which the tumor begins and the tumor location. […] Specific treatment for brain tumors will be determined by your child’s doctor based on: […] Continuous follow-up care is essential for a child diagnosed with a brain tumor.
- #6 Improving diagnosis of pediatric central nervous system tumours: aiming for early detectionhttps://pmc.ncbi.nlm.nih.gov/articles/PMC5367991/
Central nervous system (CNS) tumours account for a quarter of all cancers in children aged 1 to 19 years, despite being relatively uncommon. Survival in many cases is poor, and thus the diagnosis may be devastating. Yet for 70% of children with CNS tumours, there is potential for effective treatment with multimodal therapy by a specialized, multidisciplinary team. Early detection is essential to allow the best possible treatment by an experienced team of pediatric neurosurgeons and oncologists, to optimize outcomes. However, CNS tumours in children are often initially misdiagnosed as more common pediatric conditions, such as migraine, gastroenteritis, or psychologic or behavioural problems. […] The diagnosis of CNS tumours necessitates a comprehensive clinical history and complete examination, in addition to advanced imaging, such as computed tomography (CT) or magnetic resonance imaging (MRI) to confirm clinical suspicion.
- #7 Pediatric Brain Tumor Symptoms & Diagnosis | Baptist Health Miami Cancer Institutehttps://baptisthealth.net/services/cancer-care/miami-cancer-institute/our-approach/pediatric-cancers/brain-tumors/symptoms-and-diagnosis
Each child experiences symptoms differently. The size and location of a tumor also affect symptoms. Among the most common symptoms are: […] To diagnose and better analyze your child’s condition and help determine the best treatment your child’s doctor will complete a thorough medical history and order a number of tests.

Brain tumors represent the highest cause of mortality in the pediatric oncological population. Diagnosis is commonly performed with magnetic resonance imaging. Survival biomarkers are challenging to identify due to the relatively low numbers of individual tumor types. […] Medical imaging is an important diagnostic aid for brain tumors, since it is non-invasive and can include the whole tumor and surrounding tissue. It is also capable of probing the tumor microenvironment in vivo, improving our understanding of the in vivo neovascularization and cellularity of the tumor, as well as surrounding cerebral tissue through perfusion and diffusion imaging, respectively. […] Diffusion imaging is available on every major commercial MRI scanner and is routinely used to assess brain tumors. Apparent diffusion coefficient (ADC) maps represent the speed of water motion in the tissue and this correlated cellularity. Perfusion imaging is often acquired either with dynamic susceptibility contrast (DSC) or arterial spin labelling (ASL) techniques.

[…] A lumbar puncture removes a small amount of cerebrospinal fluid (CSF) from the spine to be examined under a microscope. It may be done as part of staging to see if a brain tumour has spread to the CSF. […] A complete blood count (CBC) measures the number and quality of white blood cells, red blood cells and platelets. A CBC is done to give the doctors a baseline that they can check against during treatment. […] Blood chemistry tests measure certain chemicals in the blood. They show how well certain organs are working and can help find problems. […] During an angiography, a contrast dye is injected into the bloodstream and x-rays are taken to map out the size and shape of blood vessels. It is used to look at the blood vessels and the flow of blood in the brain, which is helpful in planning surgery.

Magnetic resonance imaging (MRI). This imaging procedure uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of organs and structures within the body. […] X-ray. This imaging test uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs onto film. […] Bone scan. This imaging test takes X-rays of the bones after a dye has been injected that is absorbed by bone tissue. […] Angiogram. This imaging test uses a dye to visualize all the blood vessels in the brain to detect certain types of tumors. […] Lumbar puncture/spinal tap. For this procedure, a special needle is placed into the lower back and into the spinal canal around the spinal cord. A small amount of cerebrospinal fluid, which surrounds the brain and spinal cord, can be removed and sent for testing.
- #44 Tests for Brain and Spinal Cord Tumors in Children | American Cancer Societyhttps://www.cancer.org/cancer/types/brain-spinal-cord-tumors-children/detection-diagnosis-staging/how-diagnosed.html
MRI scans are very good for looking at the brain and spinal cord and are considered the best way to look for tumors in these areas. […] MRI scans can take a long time, and they require a person to stay still for several minutes at a time. […] Imaging tests such as MRI and CT scans may show that a child has a brain or spinal cord tumor. But often the type of tumor can only be determined by removing a sample of it, which is called a biopsy. […] The biopsy samples are then sent to a pathologist (a doctor specializing in diagnosis of diseases by lab tests). The pathologist looks at it under a microscope (and might do other lab tests) to determine if the tumor is benign or malignant (cancerous) and exactly what type of tumor it is. […] This test is used mainly to look for signs of cancer in the cerebrospinal fluid (CSF), which is the liquid that bathes the brain and spinal cord.
- #45 Tests to diagnose a children’s brain tumourhttps://www.cancerresearchuk.org/about-cancer/childrens-cancer/brain-tumours/tests
CT stands for computed tomography. A CT scan uses x-rays and a computer to create detailed pictures of the inside of your body. It can help doctors find out if there is a tumour and where it is. […] Blood tests can check your child’s general health, including how well their liver and kidneys are working. If your child’s doctor thinks they might have a secreting germ cell tumour, they’ll have blood tests to check for certain hormone levels. These are known as tumour markers. […] Your child’s doctor might want to take a sample of the tumour (biopsy) seen on a scan. A pathologist looks at the cells down a microscope to find out exactly what type of brain tumour it is. This is so they can be sure what treatment is best. […] Your doctor may arrange tests to look for gene changes in the sample of your child’s brain tumour. They call these changes biomarkers. This can help them get more information about the type of brain tumour, work out how quickly the brain tumour might grow, work out how likely the brain tumour will respond to treatment. […] A lumbar puncture is a test to check the fluid that circulates round the brain and spinal cord. This is called cerebrospinal fluid or CSF. A lumbar puncture can check for cancer cells or for infection in the CSF.
- #46 Tests for Brain and Spinal Cord Tumors in Children | American Cancer Societyhttps://www.cancer.org/cancer/types/brain-spinal-cord-tumors-children/detection-diagnosis-staging/how-diagnosed.html
Because some tumors (especially medulloblastomas) can spread beyond the nervous system, in some instances the doctor may recommend looking at cells in your child’s bone marrow (the soft, inner part of certain bones) to see if tumor cells have spread there. […] These lab tests are rarely used to diagnose brain and spinal cord tumors, but if your child has been sick for some time they may be done to check how well the liver, kidneys, and some other organs are working.
- #47 Diagnosis of childhood brain and spinal cord tumours | Canadian Cancer Societyhttps://cancer.ca/en/cancer-information/cancer-types/brain-and-spinal-cord-childhood/diagnosis
An MRI is considered the best way to look at tumours in the brain and spinal cord areas. It usually provides more detailed images of soft tissue than CT scans. […] CT scans are often the first imaging test done to see if there is an abnormality in the brain. If an abnormality is found, an MRI is done. […] A PET scan is used to see if abnormal areas seen on an MRI or a CT scan are likely to be cancerous. It may also be used after treatment to see if an abnormal area is a tumour or scar tissue. […] During a biopsy, the doctor removes tissues or cells from the body so they can be tested in a lab. The report from a pathologist will confirm whether or not cancer cells are found in the sample. […] Tumour marker tests can also be used to check a childs response to cancer treatment, but they can also be used to help diagnose certain types of brain and spinal cord tumours.

A small operation is done (under anaesthetic) to remove a piece of the tumour. The sample is looked at in the laboratory to find out exactly what type of tumour it is. A biopsy isn’t always done as it is sometimes better to remove the whole tumour in one operation. […] These are useful as part of diagnosis and also for monitoring response to treatment. Tests will look at how well your child can see, including any double-vision, eye movements and blind spots. […] There are different types of brain tumours and they are usually named after the type of cells they develop from. The main types are astrocytoma, ependymoma, and medulloblastoma, but there are many other, less common types. […] Malignant primary brain tumours are most likely to cause problems by causing pressure and damage to the areas around them and by spreading to the normal brain tissue close by. Sometimes, they spread to other areas distant to the original tumour.

- #56 Combining multi-site magnetic resonance imaging with machine learning predicts survival in pediatric brain tumors | Scientific Reportshttps://www.nature.com/articles/s41598-021-96189-8
Studies have shown that diffusion and perfusion imaging are able to discriminate between pediatric tumor types in vivo, with high cellularity and perfusion in high grade tumors, and vice versa for low-grade. […] In this study we have therefore taken a novel approach to the understanding of risk and survival in pediatric brain tumors through combining diffusion and perfusion MRI and combining this with both supervised and unsupervised machine learning to determine key imaging derived risk factors and novel prognostic groups. […] Whole cohort univariate cox regression revealed a number of imaging features with significantly elevated hazard ratios (HR), for example Uncorrected CBV ROI mean (HR 3.1, Confidence Intervals (CI) 1.5-6.6, p=0.003). […] Using the Bayesian imaging features, k means clustering revealed two distinct clusters, which when combined with KaplanMeier analysis revealed a significant difference between a high and low risk population (p=0.0015).

Brain tumours have no unique pathognomonic features, which often makes early diagnosis difficult. Children commonly present with symptoms that may (but do not necessarily) reflect increased intracranial pressure. […] Despite advancement in imaging techniques and better access to computed tomography and magnetic resonance imaging, the prediagnostic symptomatic interval has remained virtually constant over the last several decades. […] Time to diagnosis affects time to treatment, and delays may lead to neurologic, developmental and neuroendocrinologic morbidity, such as loss of visual pathway or hypothalamic pituitary axis with supratentorial tumours, as well as substantial long-term deficits involving physical, sensory, cognitive, neurologic and endocrine complications. […] Physicians should consider CNS tumours in the differential diagnosis for children with headache, vomiting, lethargy, ataxia, visual changes, prolonged torticollis, nystagmus, papilledema or seizures, and should consider appropriate imaging and specialist referral according to the history and a comprehensive physical examination.

Recognizing the signs of pediatric brain tumors is crucial for early diagnosis and treatment. […] Pediatric brain tumor diagnosis involves a combination of imaging tests, such as MRI and CT scans, and a biopsy for conclusive results. […] Once diagnosed, treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these approaches. The choice of treatment depends on the tumor’s type, size, and location. […] For most cases, the precise cause remains unknown, making early detection and treatment critical. […] Unlike adults, children’s brains are still growing, so doctors prefer to surgically remove tumors early to prevent further growth. After surgery, chemotherapy may be given to some children. However, doctors rarely use it for young kids due to the strong radiation beams involved, which can be risky in children.

Early and accurate diagnosis of a childhood brain tumor can increase the chances for successful treatment. […] If your child has symptoms of a brain tumor, the doctor will examine your child carefully and ask you questions about your childs and familys medical history. […] One or more diagnostic test may be used to find out if your child has a brain tumor and if it has spread. These tests also may be used to find out if treatment is working. […] If imaging tests show an area that may be a brain tumor, a biopsy almost always is necessary for diagnosis. […] A biopsy may be done during surgery in which all or part of the brain tumor is removed. […] If a tumor is difficult to reach, a CT scan may be used for to place a hollow needle inside the tumor and remove a small amount of tissue. […] A small amount of CSF (cerebrospinal fluid, which is the clear liquid in and around the brain and spine) is removed with a needle and looked at with a microscope.
