Łagodne guzy mózgu
Diagnostyka i diagnoza
Łagodne guzy mózgu stanowią około 70-72% wszystkich nowotworów mózgu i mimo swojej nazwy mogą powodować poważne zaburzenia neurologiczne ze względu na lokalizację i ucisk na struktury mózgowe. Diagnostyka tych zmian opiera się na szczegółowym wywiadzie, badaniu neurologicznym oraz zaawansowanych technikach obrazowych, z których złotym standardem jest rezonans magnetyczny (MRI) z kontrastem gadolinowym. Dodatkowe metody MRI, takie jak spektroskopia, perfuzja i dyfuzja, dostarczają informacji o składzie chemicznym, przepływie krwi i mikrostrukturze tkanek guza. Tomografia komputerowa (TK) jest często stosowana jako badanie pierwszego rzutu, zwłaszcza w stanach nagłych. Biopsja, najczęściej stereotaktyczna, pozostaje kluczowa dla ostatecznej klasyfikacji histopatologicznej i stopnia złośliwości guza, co jest niezbędne do planowania leczenia. W diagnostyce uzupełniającej wykorzystuje się także badania molekularne, EEG, badania hormonalne, okulistyczne i audiometryczne, które pomagają w ocenie funkcji i wpływu guza na organizm.
Diagnostyka łagodnych guzów mózgu
Łagodne guzy mózgu stanowią około 70-72% wszystkich nowotworów mózgu. Pomimo określenia „łagodny”, guzy te mogą powodować poważne problemy zdrowotne ze względu na swoją lokalizację i wpływ na funkcjonowanie mózgu12. Diagnostyka łagodnych guzów mózgu jest złożonym procesem, wymagającym zastosowania różnych metod i technik, aby postawić precyzyjną diagnozę.
Badanie podmiotowe i przedmiotowe
Diagnostyka łagodnego guza mózgu zazwyczaj rozpoczyna się od dokładnego wywiadu lekarskiego i badania neurologicznego. Lekarz zbiera informacje na temat objawów pacjenta, historii medycznej oraz przeprowadza badanie, które może obejmować ocenę równowagi, odruchów, koordynacji oraz innych funkcji, takich jak słuch i wzrok34. Jeżeli istnieją podejrzenia co do obecności guza mózgu, lekarz pierwszego kontaktu może skierować pacjenta na dalsze badania lub bezpośrednio do neurologa5.
Badanie neurologiczne samo w sobie nie wykrywa guza mózgu, ale pomaga lekarzowi zrozumieć, która część mózgu może mieć problem. Często wykrywane są zaburzenia równowagi, koordynacji, mowy oraz funkcji poznawczych, które mogą sugerować obecność guza6.
Badania obrazowe
Podstawowymi metodami diagnostycznymi w rozpoznawaniu łagodnych guzów mózgu są badania obrazowe, które umożliwiają wizualizację struktur mózgu oraz lokalizację potencjalnego guza7.
Rezonans magnetyczny (MRI)
Rezonans magnetyczny (MRI) jest złotym standardem w diagnostyce guzów mózgu8. Wykorzystuje on silne pole magnetyczne i fale radiowe do tworzenia szczegółowych obrazów mózgu. MRI wykazuje znacznie większą czułość w wykrywaniu guzów mózgu niż inne badania obrazowe, pozwalając na dokładniejszą ocenę ich wielkości, lokalizacji oraz charakterystyki9.
Najczęściej wykonuje się badanie MRI z kontrastem (gadolinem), które umożliwia lepsze uwidocznienie guza i jego granic10. Istnieją różne rodzaje badań MRI, które mogą dostarczyć dodatkowych informacji:
- MRI spektroskopowe – pozwala na określenie składu chemicznego tkanek
- MRI perfuzyjne – ocenia przepływ krwi w obrębie guza
- MRI dyfuzyjne – ocenia strukturę tkanek na poziomie mikroskopowym
Jednak należy pamiętać, że mimo wysokiej czułości, sam MRI nie jest w stanie definitywnie określić, czy guz jest łagodny czy złośliwy. Może dostarczyć pewnych wskazówek – łagodne guzy często mają gładkie, dobrze zdefiniowane granice, podczas gdy guzy złośliwe mogą wydawać się postrzępione lub nieregularne12.
Tomografia komputerowa (TK)
Tomografia komputerowa (TK) wykorzystuje promieniowanie rentgenowskie do tworzenia szczegółowych obrazów mózgu. Jest to badanie szybsze i często bardziej dostępne niż MRI, dlatego często stanowi pierwsze badanie obrazowe wykonywane u pacjentów z podejrzeniem guza mózgu13. TK może wykryć problemy w mózgu i wokół niego, takie jak krwawienia, obrzęk czy obecność guza. Wyniki TK dostarczają lekarzowi wskazówek co do dalszego postępowania diagnostycznego14.
W przypadkach nagłych, takich jak uraz głowy czy nagłe wystąpienie objawów neurologicznych, TK jest często badaniem z wyboru ze względu na szybkość wykonania. Jeśli TK wykaże obecność guza, zwykle zaleca się wykonanie bardziej szczegółowego badania MRI1516.
Inne badania obrazowe
W niektórych przypadkach mogą być wykonywane dodatkowe badania obrazowe:
- PET (pozytonowa tomografia emisyjna) – może pomóc w rozróżnieniu między guzem a innymi zmianami, takimi jak blizny pooperacyjne czy zmiany po radioterapii17
- Angiografia mózgowa – badanie wykorzystywane do oceny naczyń krwionośnych w mózgu, szczególnie przydatne w przypadku guzów silnie unaczynionych18
- PET-CT – połączenie PET i tomografii komputerowej, które może dostarczyć bardziej kompleksowych informacji o guzie19
Biopsja
Biopsja, czyli pobranie próbki tkanki guza do badania mikroskopowego, jest kluczowym elementem diagnostyki guzów mózgu20. Pozwala ona na określenie typu komórek tworzących guza, co jest niezbędne do postawienia ostatecznej diagnozy i zaplanowania odpowiedniego leczenia21.
Biopsja może być przeprowadzona na kilka sposobów:
- Biopsja stereotaktyczna – minimalnie inwazyjna procedura, podczas której igła jest wprowadzana do guza przez małe otwór w czaszce, a lokalizacja guza jest precyzyjnie określana za pomocą specjalnego systemu nawigacji
- Biopsja otwarta – wykonywana podczas kraniotomii (operacyjnego otwarcia czaszki), często jako część procedury usunięcia guza
- Neuroendoskopia – technika wykorzystująca endoskop do pobrania próbki tkanki z guza22
Próbka pobrana podczas biopsji jest następnie badana przez neuropatologa, który ocenia rodzaj komórek, ich wygląd oraz inne cechy, które mogą pomóc w określeniu typu guza i jego stopnia złośliwości23. Wyniki biopsji są zazwyczaj najbardziej miarodajne w określeniu, czy guz jest łagodny czy złośliwy24.
W niektórych przypadkach biopsja może być trudna do przeprowadzenia ze względu na lokalizację guza w trudno dostępnych obszarach mózgu lub blisko istotnych struktur nerwowych. W takich sytuacjach diagnoza może opierać się głównie na wynikach badań obrazowych25.
Inne badania diagnostyczne
W zależności od lokalizacji i typu guza, mogą być przeprowadzane dodatkowe badania diagnostyczne:
- Badania krwi – mogą być pomocne w ocenie ogólnego stanu zdrowia pacjenta oraz funkcjonowania różnych narządów, co jest istotne przed planowanym leczeniem. W przypadku niektórych guzów, takich jak guzy przysadki mózgowej, badania hormonalne mogą pomóc w diagnostyce26
- Elektroenencefalografia (EEG) – badanie aktywności elektrycznej mózgu, szczególnie użyteczne u pacjentów z napadami padaczkowymi spowodowanymi przez guza27
- Punkcja lędźwiowa – badanie płynu mózgowo-rdzeniowego, które może być wykonywane w celu wykluczenia innych chorób lub w przypadku podejrzenia rozprzestrzeniania się guza do płynu mózgowo-rdzeniowego28
- Badania okulistyczne – ocena pola widzenia i dna oka, które mogą wykazać objawy zwiększonego ciśnienia wewnątrzczaszkowego, takie jak obrzęk tarczy nerwu wzrokowego29
- Badania audiometryczne – ocena słuchu, szczególnie istotna w przypadku guzów zlokalizowanych w okolicy nerwu słuchowego, takich jak nerwiak osłonkowy (schwannoma)30
Klasyfikacja i stopniowanie łagodnych guzów mózgu
Po przeprowadzeniu badań diagnostycznych i pobraniu próbki guza, neuropatolog określa typ guza oraz jego stopień złośliwości. Klasyfikacja i stopniowanie guzów mózgu są kluczowe dla ustalenia rokowania i planowania leczenia31.
System klasyfikacji WHO
Światowa Organizacja Zdrowia (WHO) opracowała system klasyfikacji i stopniowania guzów mózgu, który jest powszechnie stosowany na całym świecie. Klasyfikacja ta opiera się na ocenie histologicznej komórek guza oraz ich cechach molekularnych32.
Guzy mózgu są klasyfikowane według skali od I do IV stopnia, gdzie:
- Stopień I i II – guzy łagodne (niskiego stopnia), wolno rosnące, o dobrze zdefiniowanych granicach, rzadko rozprzestrzeniające się do innych części mózgu3334
- Stopień III i IV – guzy złośliwe (wysokiego stopnia), szybko rosnące, z tendencją do inwazji okolicznych tkanek35
Warto zauważyć, że określenie „łagodny” w kontekście guzów mózgu może być mylące. Mimo że guzy stopnia I i II są technicznie łagodne, nadal mogą powodować poważne problemy zdrowotne ze względu na lokalizację w mózgu i wywierany ucisk na otaczające struktury36.
Markery molekularne
W ostatnich latach coraz większe znaczenie w diagnostyce guzów mózgu mają markery molekularne. Są to specyficzne zmiany genetyczne lub białkowe w komórkach guza, które mogą dostarczyć dodatkowych informacji o jego charakterystyce i potencjalnym przebiegu klinicznym37.
Badania molekularne mogą pomóc w:
- Dokładniejszym określeniu typu guza
- Prognozowaniu przebiegu choroby
- Przewidywaniu odpowiedzi na określone formy leczenia
- Identyfikacji potencjalnych celów dla terapii celowanej38
Najczęstsze typy łagodnych guzów mózgu
Do najczęstszych typów łagodnych guzów mózgu należą:
- Oponiaki (meningioma) – najczęstszy typ łagodnego guza mózgu, stanowiący około 39,7% wszystkich guzów mózgu. Rozwija się z komórek opon mózgowych, zwykle rośnie powoli i ma dobrze zdefiniowane granice3940
- Nerwiaki osłonkowe (schwannoma) – rozwijają się z komórek osłonek nerwów czaszkowych, najczęściej z nerwu przedsionkowo-ślimakowego (nerwiaki nerwu VIII), odpowiedzialnego za słuch i równowagę41
- Gruczolaki przysadki mózgowej – rozwijają się z przysadki mózgowej, mogą wydzielać hormony lub być hormonalnie nieaktywne42
- Gwiaździaki niskiego stopnia – rozwijają się z astrocytów, typu komórek glejowych w mózgu43
- Naczyniaki krwionośne (hemangioblastoma) – rozwijają się z komórek wyściełających naczynia krwionośne w mózgu, rdzeniu kręgowym i pniu mózgu44
- Czaszkogardlaki (craniopharyngioma) – rozwijają się w okolicy przysadki mózgowej i podwzgórza, często u dzieci45
Proces diagnostyczny i konsultacje wielospecjalistyczne
Diagnostyka łagodnych guzów mózgu wymaga współpracy specjalistów z różnych dziedzin, aby zapewnić kompleksową ocenę stanu pacjenta i opracować optymalny plan leczenia46.
Konsultacje wielospecjalistyczne
W procesie diagnostyki i leczenia łagodnych guzów mózgu zwykle uczestniczą:
- Neurolog – specjalista od chorób układu nerwowego, przeprowadzający badanie neurologiczne i interpretujący jego wyniki
- Neurochirurg – specjalista przeprowadzający zabiegi chirurgiczne w obrębie mózgu i układu nerwowego
- Neuroradiolog – specjalista interpretujący badania obrazowe mózgu
- Neuropatolog – specjalista badający próbki tkanek pod mikroskopem w celu określenia typu guza
- Onkolog – specjalista zajmujący się leczeniem nowotworów
- Radioterapeuta – specjalista planujący i nadzorujący radioterapię4748
Zespół specjalistów regularnie spotyka się, aby omówić wyniki badań i opracować indywidualny plan leczenia dla każdego pacjenta. Takie podejście wielodyscyplinarne zapewnia kompleksową opiekę i optymalne wyniki leczenia49.
Wyzwania diagnostyczne
Diagnostyka łagodnych guzów mózgu może stanowić wyzwanie z kilku powodów:
- Wiele guzów mózgu ma podobny wygląd w badaniach obrazowych, co utrudnia ich rozróżnienie bez biopsji50
- Guzy łagodne mogą rosnąć bardzo powoli i pozostawać bezobjawowe przez długi czas51
- Niektóre lokalizacje w mózgu są trudno dostępne dla biopsji, co utrudnia pobranie próbki tkanki52
- Objawy guzów mózgu mogą być niespecyficzne i przypominać inne schorzenia neurologiczne53
Te wyzwania podkreślają znaczenie dokładnej diagnostyki i współpracy specjalistów z różnych dziedzin w celu postawienia prawidłowej diagnozy54.
Nowoczesne techniki diagnostyczne
Rozwój technologii medycznych przyczynia się do ciągłego doskonalenia metod diagnostycznych w przypadku łagodnych guzów mózgu55.
Zaawansowane techniki obrazowania
Nowocześniejsze techniki obrazowania mogą dostarczyć dodatkowych informacji o charakterystyce guza:
- Funkcjonalny rezonans magnetyczny (fMRI) – pozwala na wizualizację aktywności różnych obszarów mózgu, co jest szczególnie istotne przy planowaniu operacji guzów zlokalizowanych w pobliżu istotnych funkcjonalnie obszarów mózgu56
- Traktografia dyfuzyjna – technika MRI umożliwiająca wizualizację szlaków istotnych włókien nerwowych w mózgu, co pomaga w planowaniu operacji z zachowaniem tych struktur
- MRI perfuzyjne – ocenia przepływ krwi w obrębie guza, co może pomóc w rozróżnieniu między guzami łagodnymi a złośliwymi
- MRI spektroskopowe – dostarcza informacji o składzie chemicznym tkanek, co może pomóc w identyfikacji typu guza57
Biopsja płynna
Biopsja płynna to rodzaj badania krwi, które wykrywa materiał genetyczny z komórek guza uwolniony do krwioobiegu. Badania nad wykorzystaniem biopsji płynnej w diagnostyce guzów mózgu są obiecujące i mogą w przyszłości zrewolucjonizować proces diagnostyczny58.
Potencjalne korzyści biopsji płynnej obejmują:
- Mniej inwazyjną alternatywę dla tradycyjnej biopsji
- Możliwość monitorowania odpowiedzi na leczenie
- Wczesne wykrywanie nawrotu guza59
Sztuczna inteligencja w diagnostyce
Technologie oparte na sztucznej inteligencji (AI) są coraz częściej wykorzystywane w diagnostyce guzów mózgu. Algorytmy AI mogą analizować obrazy radiologiczne i pomagać w identyfikacji guzów, ich klasyfikacji oraz planowaniu leczenia60.
Potencjalne zastosowania AI w diagnostyce guzów mózgu obejmują:
- Automatyczne wykrywanie i segmentację guzów w badaniach obrazowych
- Prognozowanie typu histologicznego guza na podstawie cech radiologicznych
- Wspomaganie diagnostyki śródoperacyjnej61
Znaczenie wczesnej i dokładnej diagnostyki
Wczesna i dokładna diagnostyka łagodnych guzów mózgu ma kluczowe znaczenie dla skutecznego leczenia i poprawy rokowania pacjentów62.
Korzyści wczesnej diagnostyki
Wczesne wykrycie łagodnego guza mózgu może przynieść liczne korzyści:
- Możliwość całkowitego usunięcia guza, zanim urośnie do znacznych rozmiarów lub zaangażuje istotne struktury mózgu63
- Zapobieganie rozwojowi nieodwracalnych uszkodzeń neurologicznych spowodowanych uciskiem guza na otaczające tkanki64
- Zwiększenie opcji terapeutycznych dostępnych dla pacjenta65
- Potencjalnie lepsze wyniki leczenia i jakość życia po leczeniu66
Dokładność diagnostyczna
Dokładna diagnoza, obejmująca określenie typu guza, jego lokalizacji, rozmiaru i potencjalnego wpływu na otaczające struktury, jest niezbędna do zaplanowania odpowiedniego leczenia67.
Ważne aspekty dokładnej diagnostyki obejmują:
- Prawidłowe określenie typu histologicznego guza, co wpływa na wybór metody leczenia68
- Dokładne określenie granic guza, co jest istotne przy planowaniu zabiegu chirurgicznego69
- Identyfikacja markerów molekularnych, które mogą wpływać na rokowanie i odpowiedź na leczenie70
- Ocena funkcjonalna obszarów mózgu otaczających guza, co jest kluczowe dla zachowania funkcji neurologicznych po leczeniu71
Podsumowanie
Diagnostyka łagodnych guzów mózgu jest złożonym procesem, wymagającym zastosowania różnych metod i technik, od badania neurologicznego, przez zaawansowane badania obrazowe, po biopsję i analizę histopatologiczną. Dokładna diagnoza jest kluczowa dla określenia optymalnego planu leczenia, który może obejmować obserwację, zabieg chirurgiczny, radioterapię lub kombinację tych metod72.
Wczesne wykrycie i dokładna diagnostyka łagodnych guzów mózgu mogą znacząco poprawić rokowanie pacjenta poprzez umożliwienie skutecznego leczenia, zanim guz spowoduje nieodwracalne uszkodzenia neurologiczne. Współpraca wielodyscyplinarnego zespołu specjalistów, wykorzystanie nowoczesnych technik diagnostycznych oraz indywidualne podejście do każdego pacjenta są niezbędne do zapewnienia najlepszych wyników leczenia73.
Mimo że łagodne guzy mózgu nie są nowotworami złośliwymi, nadal mogą stanowić poważne zagrożenie dla zdrowia i życia pacjenta ze względu na swoje położenie w mózgu. Dlatego tak istotne jest, aby pacjenci z objawami sugerującymi obecność guza mózgu byli szybko diagnozowani i leczeni przez doświadczonych specjalistów w ośrodkach dysponujących odpowiednim zapleczem diagnostycznym i terapeutycznym7475.

Each year, more than 67,000 Americans will be diagnosed with a benign (non-malignant) brain tumor. Often, when people hear the words benign brain tumor, their immediate reaction may be relief that at least its not cancer, assuming that a benign tumor means no severe symptoms and no lasting impact. But for those living with a benign brain tumor, the reality can be far more complicated. Benign does not necessarily mean harmless. Benign does not mean easy. Benign is not fine. […] A benign brain tumor involves abnormal growths in the brain that can disrupt essential functions. These tumors can press on critical areas, causing debilitating symptoms, long-term complications, and a significant decline in quality of life. Many patients struggle with symptoms that affect their physical abilities, cognition, emotions, and social interactions.

Approximately 72% of all brain tumors are benign. […] An estimated 67,440 will be non-malignant (benign) in 2023. […] Non-malignant meningiomas are the most commonly occurring primary non-malignant brain tumors, accounting for 39.7% of all tumors and 55.4% of all non-malignant tumors. […] For patients with non-malignant brain tumors, the average five-year relative survival rate is 91.8%. […] The most common primary non-malignant brain tumor, meningioma, has an average five-year survival of 88.2% after diagnosis. […] The five-year relative survival rate for adults diagnosed with a primary brain tumor is 72.5%. […] The five-year relative survival rate for those ages 40+ years is 90.3% for non-malignant tumors. […] Non-malignant primary brain tumors occur more often in females (64.4%) than in males (35.6%).
- #3 Non-cancerous (benign) brain tumours – NHShttps://www.nhs.uk/conditions/non-cancerous-benign-brain-tumours/
A brain tumour is where cells in the brain grow in an uncontrolled way. Non-cancerous tumours (also called low-grade or benign tumours) usually grow slowly and are less likely to spread than cancerous tumours. […] If you have symptoms of a brain tumour or another problem affecting the brain, a GP may do some simple tests to check things like your eyesight, balance and memory. […] If there are signs of a possible problem, they may refer you for a brain scan or to a brain specialist (neurologist) for more tests. […] The main test to check for a tumour is a brain scan (usually an MRI scan). This can show if you have a possible tumour, but you’ll usually need more tests to confirm it. […] Most people have a procedure to remove a small sample of cells for testing. This is called a biopsy.

Many people are diagnosed with a brain tumour when they go to hospital after having a seizure (fit) or other sudden symptoms. Other people go to see their GP about symptoms. […] If your GP thinks you may have a brain tumour, they will arrange for you to have a brain scan. Or they may refer you directly to a neurologist. This is a doctor who specialises in brain disorders. […] You may have already had a CT scan of your brain. A CT scan can show some changes, such as bleeding or swelling in the brain. But you will usually need to also have a brain MRI scan. Having an MRI scan is very important. This is because MRI scans can give much more detailed information about brain tumours. This information helps guide the doctors when planning your treatment. […] You may need to have more than 1 type of MRI. If you have had an MRI scan without the injection of dye (contrast), you will usually need to have another MRI with dye. The dye helps to show the tumour in more detail.

They can help to find out more about the position of the tumour and how close it is to normal brain structures. They may also be used to find out more about the type and the activity of the tumour. Some MRI scans provide detailed images of blood vessels in the brain or show how different parts of the brain are working. […] If you are not able to have an MRI scan, for example if you have a pacemaker that cannot go into an MRI scanner, you doctor will discuss this with you. […] You may also have some other tests and scans. […] At the hospital, you will also have a neurological examination. This is a check of your nervous system. […] Tests and scans for brain tumours include: […] Brain CT scan […] A CT scan makes a three-dimensional (3D) picture of the brain. The test only takes a few minutes and is painless. You may have an injection of a dye into a vein in your arm. This is called contrast. It helps show certain areas of the brain more clearly.
- #12 Can an MRI Tell If a Tumor Is Benign? | Tisch Brain Tumor Centerhttps://tischbraintumorcenter.duke.edu/blog/can-mri-tell-if-tumor-benign
An MRI can show if there’s a tumor and give clues about whether it’s benign or malignant. Radiologists, the doctors who read these scans, look for certain signs. For example, benign tumors often have smooth, well-defined edges, while malignant ones can appear jagged or irregular. But here’s the catch: these clues aren’t always 100% reliable. […] To know for sure if a tumor is benign or malignant, you’ll likely need additional tests, like a biopsy. This involves removing a small sample of the tumor tissue to examine it under a microscope. […] When it comes to brain tumors, MRIs are the go-to method for spotting them. They can help distinguish between more common benign brain tumors, like meningiomas, and malignant ones, like gliomas. But even with these scans, a biopsy is usually necessary for a firm diagnosis.

[…] To diagnose a meningioma, your healthcare provider will perform a physical examination and a neurological examination. Theyll also recommend imaging tests, such as: Brain MRI (magnetic resonance imaging): The best imaging test to diagnose meningioma is a brain MRI scan with contrast. […] Sometimes, if the diagnosis is in doubt, a biopsy may be needed to confirm the diagnosis of meningioma and exclude other possible diagnoses. Your neurosurgeon will perform the biopsy to obtain a small tissue sample. The tissue sample will be examined to establish a diagnosis, determine whether the tumor is benign or malignant, and decide on a tumor grade.
- #24 Can an MRI Tell If a Tumor Is Benign? | Tisch Brain Tumor Centerhttps://tischbraintumorcenter.duke.edu/blog/can-mri-tell-if-tumor-benign
An MRI can show if there’s a tumor and give clues about whether it’s benign or malignant. Radiologists, the doctors who read these scans, look for certain signs. For example, benign tumors often have smooth, well-defined edges, while malignant ones can appear jagged or irregular. But here’s the catch: these clues aren’t always 100% reliable. […] To know for sure if a tumor is benign or malignant, you’ll likely need additional tests, like a biopsy. This involves removing a small sample of the tumor tissue to examine it under a microscope. […] When it comes to brain tumors, MRIs are the go-to method for spotting them. They can help distinguish between more common benign brain tumors, like meningiomas, and malignant ones, like gliomas. But even with these scans, a biopsy is usually necessary for a firm diagnosis.
- #25 How We Diagnose Brain Tumors | Dana-Farber Cancer Institutehttps://www.dana-farber.org/cancer-care/types/brain-tumors/diagnosis
At the Center for Neuro-Oncology, diagnostic imaging is central before, during, and after treatment. […] All patients with a suspected brain tumor routinely have diagnostic scans within 48 hours. […] If imaging tests confirm that a brain tumor or mass is present, a biopsy is typically performed. […] For certain tumors, a biopsy or surgery cannot be done safely because of where the tumor has formed in the brain or spinal cord. […] Sometimes the results of imaging tests and other procedures show that the tumor is very likely to be benign, and a biopsy is not done. […] The diagnosis of low-grade gliomas includes a neurological exam, diagnostic imaging, and a biopsy.

A brain tumor is a growth of abnormal cells that have formed in the brain. Some brain tumors are malignant (cancerous), while others are not (non-malignant, non-cancerous or benign). A brain tumor can form in the brain or other parts of the central nervous system (CNS), such as the spine or cranial nerves. The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory. A tumor can affect the brainâs ability to work properly and adequately perform such functions. […] Tumor grade has long been a way to define the aggressiveness of a tumor, particularly for malignant brain tumors such as glioma but also for non-malignant (benign) brain tumors including meningioma. […] Not all brain tumors are the same. Some tumors have differences in the genetic or molecular makeup of the cells. These differences are called molecular markers, or biomarkers. Molecular markers are becoming increasingly important for brain tumor diagnosis and treatment. For example, some molecular markers help determine how aggressive a tumor may be. Others determine how responsive a tumor will be to treatment.

Many types of brain and spinal cord tumors look similar when the cells are examined under the microscope. Even with trained pathologists examining tissue samples, up to 10% of people with a brain or spinal cord tumor receive the wrong diagnosis at first. This can potentially affect outcomes, because tumors that look similar at the cellular level may require very different treatments. […] NCI-supported researchers are studying ways to improve the diagnosis of brain and spinal cord tumors. For example: A type of blood test called a liquid biopsy was able to distinguish between several different types of brain tumors in adult patients. This test checks for chemical changes in tumor DNA that has been shed into the bloodstream. Researchers hope that such tests could not just improve the accuracy of diagnoses but someday be used to diagnose brain tumors without the need for invasive surgery to get biopsy samples.

At its core, a brain tumor is an abnormal growth or mass of cells within the brain. These growths can be either benign (non-cancerous) or malignant (cancerous), each presenting unique challenges and considerations. […] In cases of benign brain tumors, the dormancy period can be even more prolonged. These slow-growing growths may remain inconspicuous for many years until they reach a size significant enough to impact brain function and elicit noticeable symptoms. The specific symptoms experienced will depend on the location of the benign tumor within the brain. […] Brain cancer is diagnosed through a combination of medical history assessments, physical examinations, and various diagnostic tests. Imaging studies, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, are commonly used to visualize the brain and identify any abnormal growths or tumors.
- #52 How We Diagnose Brain Tumors | Dana-Farber Cancer Institutehttps://www.dana-farber.org/cancer-care/types/brain-tumors/diagnosis
At the Center for Neuro-Oncology, diagnostic imaging is central before, during, and after treatment. […] All patients with a suspected brain tumor routinely have diagnostic scans within 48 hours. […] If imaging tests confirm that a brain tumor or mass is present, a biopsy is typically performed. […] For certain tumors, a biopsy or surgery cannot be done safely because of where the tumor has formed in the brain or spinal cord. […] Sometimes the results of imaging tests and other procedures show that the tumor is very likely to be benign, and a biopsy is not done. […] The diagnosis of low-grade gliomas includes a neurological exam, diagnostic imaging, and a biopsy. […] The diagnosis involves a physical exam, neurological exam, imaging of the brain or spine (depending on the patient’s symptoms), and a specific biopsy based on the location of the tumor. […] The diagnosis of a meningioma involves a physical exam, a neurological exam, diagnostic imaging, and a biopsy.

Even a benign tumor thats growing inside the head is potentially dangerous,” says Robert Fenstermaker, MD, Chair of Neurosurgery at Roswell Park Comprehensive Cancer Center. „Theres only so much room inside the skull, and the brain occupies most of it. Even if a brain tumor is benign and growing slowly, eventually the brain wont be able to tolerate that, and symptoms will develop, which can be life-threatening. […] Most benign tumors are treated with surgery, focused radiation or a combination of the two. Increasingly, were finding that a combination is better than either one by itself. If a tumor is large, its hard to treat it with just radiation therapy. Surgery will help reduce the tumor’s size, says Dr. Fenstermaker. […] At the same time, it may not be safe to remove the entire tumor. It could be touching or encasing blood vessels or other critical structures, such as nerves, and trying to remove the entire tumor could damage those structures. What were doing is reducing the size of those tumors with surgery and then treating them with focused radiation, such as Gamma Knife radiotherapy, to control whats left.

Types of Benign Brain Tumors include Chordomas, which are benign, slow-growing tumors that are most prevalent in people ages 50 to 60. Craniopharyngiomas typically are benign, but are difficult tumors to remove because of their location near critical structures deep in the brain. Meningiomas are the most common benign intracranial tumors, comprising 10 to 15 percent of all brain neoplasms, although a very small percentage are malignant. Pituitary adenomas are the most common intracranial tumors after gliomas, meningiomas and schwannomas. The large majority of pituitary adenomas are benign and fairly slow-growing. Schwannomas are common benign brain tumors in adults. They arise along nerves, comprised of cells that normally provide the electrical insulation for the nerve cells. […] Sometimes the only way to make a definitive diagnosis of a brain tumor is through a biopsy. The neurosurgeon performs the biopsy and the pathologist makes the final diagnosis, determining whether the tumor appears benign or malignant, and grading it accordingly. […] Sophisticated imaging techniques can pinpoint brain tumors. Diagnostic tools include computed tomography (CT or CAT scan) and magnetic resonance imaging (MRI). Other MRI sequences can help the surgeon plan the resection of the tumor based on the location of the normal nerve pathways of the brain.

A brain tumor is a mass of cells that have grown out of control and formed in or near your brain. Brain tumors can be benign (not cancer) or malignant (cancer). Most benign tumors grow slowly and do not spread to other parts of your body. As a benign brain tumor grows, it can cause symptoms. […] Often, imaging tests and a biopsy are done to find out what kind of tumor you have. […] Treatment for your benign brain tumor will depend on many factors such as the type of tumor, where it is, how big it is, your age, and if the tumor is causing symptoms. The most common treatments for benign brain tumors are surgery and radiation. Your provider will decide the best treatment for you. […] If your tumor is small and isn’t causing symptoms your provider may suggest a watch-and-wait approach. If your provider sees that the tumor is getting bigger or you are having symptoms they may decide to treat it. Some tumors never need treatment. […] Some benign brain tumors can come back after treatment, this is called recurrence. It is important to continue your follow-up care plan. Follow-up care can include imaging (MRI), blood work, and physical examinations. Be sure to talk to your provider about any new or worsening symptoms.
