Przerzuty do mózgu
Objawy
Przerzuty do mózgu stanowią wtórne ogniska nowotworowe powstałe w wyniku hematogennego rozsiewu komórek z pierwotnego nowotworu. Objawy kliniczne są zróżnicowane i zależą od lokalizacji, liczby oraz wielkości zmian, a także mechanizmów patofizjologicznych takich jak wzrost ciśnienia śródczaszkowego, naciekanie tkanki mózgowej, obrzęk czy krwawienie. Najczęstsze symptomy to bóle głowy (40-50% pacjentów), napady padaczkowe, zaburzenia funkcji poznawczych, niedowłady jednostronne, zaburzenia mowy i zmysłów oraz objawy związane z lokalizacją przerzutów (np. ataksja przy zajęciu móżdżku). Progresja objawów jest zwykle stopniowa, w odróżnieniu od nagłego początku udaru, a nasilenie symptomów koreluje z rozwojem choroby i wzrostem ciśnienia śródczaszkowego.
Objawy przerzutów do mózgu
Przerzuty do mózgu (ang. brain metastases) to guzy, które powstają w wyniku rozprzestrzenienia się komórek nowotworowych z pierwotnego ogniska nowotworowego znajdującego się w innej części ciała do tkanki mózgowej. Objawy przerzutów do mózgu mogą być różnorodne i zależą od wielu czynników, takich jak lokalizacja, wielkość i liczba zmian przerzutowych oraz szybkość ich wzrostu. 12
Najczęstsze objawy przerzutów do mózgu
Do najczęstszych objawów przerzutów do mózgu należą:
- Bóle głowy – występują u około 40-50% pacjentów z przerzutami do mózgu i często są pierwszym objawem. Bóle te zwykle nasilają się z czasem, są oporne na standardowe leki przeciwbólowe, mogą być silniejsze rano oraz nasilać się przy leżeniu, pochylaniu się lub parciu (np. podczas wypróżniania). Często towarzyszą im nudności i wymioty. 345
- Napady padaczkowe (drgawki) – mogą mieć różne postaci, od drobnych drgawek ust czy dłoni, przez napady częściowe (podczas których pacjent pozostaje przytomny), aż po uogólnione napady drgawkowe. Mogą objawiać się także jako epizody drętwienia, mrowienia, niekontrolowanych ruchów kończyn, trudności w mówieniu, dziwnych zapachów lub wrażeń, epizodów wpatrywania się i braku reakcji. 36
- Zmiany funkcji poznawczych i zachowania – w tym zaburzenia pamięci, trudności z koncentracją, dezorientacja, zmiany osobowości oraz wahania nastroju. Pacjent może stać się wycofany, rozdrażniony lub nieefektywny w pracy. Depresja i lęk, zwłaszcza jeśli rozwijają się nagle, mogą być wczesnymi objawami guza mózgu. 72
- Osłabienie lub niedowład – najczęściej jednostronne, dotyczące twarzy, ramion lub nóg. 81
- Zaburzenia mowy – trudności w znajdowaniu słów, mówienie niezrozumiałe lub niemożność wyrażania albo rozumienia języka. 79
- Zaburzenia zmysłów – w tym problemy ze wzrokiem (podwójne lub nieostre widzenie), słuchem, węchem lub smakiem. 710
- Zaburzenia równowagi i koordynacji – trudności w chodzeniu, niezborność ruchowa. 15
- Nudności i wymioty – często towarzyszą bólom głowy, mogą być silniejsze rano. 14
Objawy związane z lokalizacją przerzutów
Objawy mogą różnić się w zależności od konkretnej lokalizacji przerzutów w mózgu:
- Przerzuty w płacie czołowym – zmiany osobowości, zaburzenia zachowania, osłabienie po przeciwnej stronie ciała. 7
- Przerzuty w płacie skroniowym – zaburzenia pamięci, trudności w rozumieniu mowy, napady padaczkowe. 1112
- Przerzuty w płacie ciemieniowym – zaburzenia czucia, trudności z orientacją przestrzenną, problemy z percepcją sensoryczną. 1213
- Przerzuty w płacie potylicznym – zaburzenia widzenia, w tym nieostre widzenie i trudności z percepcją wzrokową. 11
- Przerzuty w móżdżku – zaburzenia równowagi, koordynacji i chodu, ataksja. 1214
- Przerzuty w pniu mózgu – zmiany tętna i częstości oddechów. 715
Mechanizmy powodujące objawy przerzutów do mózgu
Przerzuty do mózgu mogą powodować objawy poprzez następujące mechanizmy:
- Wzrost ciśnienia śródczaszkowego – gdy guzy rosną, zwiększają ciśnienie wewnątrz czaszki, co może prowadzić do bólów głowy, nudności, wymiotów i zaburzeń świadomości. U większości pacjentów objawy przerzutów do mózgu są spowodowane właśnie rozrostem zmian i zwiększonym ciśnieniem śródczaszkowym. 616
- Naciekanie i niszczenie tkanki mózgowej – guzy mogą bezpośrednio niszczyć okoliczną tkankę mózgową, powodując deficyty neurologiczne. 16
- Ucisk na otaczającą tkankę – guzy mogą uciskać sąsiadujące struktury mózgu, zaburzając ich funkcje. 1617
- Obrzęk mózgu – wokół guzów często rozwija się obrzęk, który dodatkowo zwiększa ciśnienie wewnątrzczaszkowe i nasila objawy. 1618
- Blokowanie krążenia płynu mózgowo-rdzeniowego – przerzuty mogą blokować normalny przepływ płynu mózgowo-rdzeniowego, prowadząc do wodogłowia. 16
- Krwawienie do mózgu – niektóre rodzaje przerzutów (szczególnie z czerniaka, raka płuca, tarczycy, nerek) mają tendencję do krwawienia, co może powodować nagłe pogorszenie stanu neurologicznego. 1619
Progresja przerzutów do mózgu
Naturalny przebieg choroby
Przerzuty do mózgu zazwyczaj mają charakter postępujący – objawy pojawiają się stopniowo i z czasem nasilają się, w miarę jak guzy rosną i wywierają coraz większy nacisk na otaczającą tkankę mózgową. 220 W przeciwieństwie do udaru mózgu, gdzie objawy pojawiają się nagle, większość objawów przerzutów do mózgu rozwija się powoli i pogarsza się z upływem czasu. 2
Progresja przerzutów do mózgu może przebiegać odmiennie w zależności od rodzaju pierwotnego nowotworu, liczby i lokalizacji przerzutów oraz reakcji na leczenie. 2 Niektóre przerzuty, jak te pochodzące z raka płuca, mają tendencję do szybszego rozprzestrzeniania się do mózgu niż inne nowotwory. 21
Czynniki wpływające na progresję
Na przebieg i progresję przerzutów do mózgu wpływają następujące czynniki:
- Rodzaj pierwotnego nowotworu – niektóre nowotwory, takie jak drobnokomórkowy rak płuca, czerniak czy rak piersi HER2-dodatni, mają większą tendencję do tworzenia przerzutów do mózgu. 2223
- Liczba przerzutów – pacjenci z pojedynczym przerzutem mają lepsze rokowanie niż ci z wieloma zmianami przerzutowymi. 2425
- Obecność przerzutów poza mózgiem – skuteczność leczenia przerzutów do mózgu jest często determinowana przez kontrolę pierwotnego nowotworu. W przypadku braku kontroli pierwotnego raka, leczenie przerzutów do mózgu byłoby daremnym wysiłkiem. 2627
- Wiek pacjenta – pacjenci poniżej 65 roku życia mają zazwyczaj lepsze rokowanie. 27
- Stan ogólny pacjenta – ogólna kondycja zdrowotna pacjenta wpływa na tolerancję leczenia i przeżycie. 2621
- Typ histologiczny nowotworu – niektóre rodzaje nowotworów lepiej reagują na leczenie, co wpływa na kontrolę przerzutów w mózgu. 17
Zmiany objawów w czasie progresji
W miarę postępu choroby, objawy przerzutów do mózgu mogą zmieniać się i nasilać:
- Nasilenie zmęczenia – postępujące zmęczenie jest jednym z najczęstszych objawów u pacjentów z przerzutami do mózgu i może być związane z krótszym czasem przeżycia. 2829
- Pogorszenie funkcji poznawczych – zwiększające się trudności z koncentracją, problemy z pamięcią i myśleniem wiążą się z wyższym ryzykiem zgonu. 29
- Utrata apetytu – nasilająca się utrata apetytu jest związana z krótszym czasem przeżycia. 29
- Zaburzenia równowagi – narastające problemy z równowagą korelują z wyższym ryzykiem zgonu. 29
- Nudności – zwiększone nudności w trakcie progresji choroby wiążą się z wyższym ryzykiem zbliżającego się zgonu. 29
- Nasilenie bólów głowy – progresywne nasilanie się bólów głowy jest związane z rosnącym ciśnieniem śródczaszkowym. 30
W końcowych stadiach choroby mogą wystąpić dodatkowe objawy, takie jak:
- Znaczne pogorszenie funkcji poznawczych, z nasilającą się dezorientacją i splątaniem. 31
- Trudności z mówieniem i połykaniem. 31
- Postępujące osłabienie fizyczne i ograniczenie mobilności. 11
- Zmiany w zachowaniu i osobowości, w tym wahania nastroju. 31
- Obniżony poziom świadomości, w skrajnych przypadkach prowadzący do śpiączki. 14
Rokowanie i czas przeżycia
Rokowanie dla pacjentów z przerzutami do mózgu jest zróżnicowane i zależy od wielu czynników. Bez leczenia średni czas przeżycia wynosi od jednego do dwóch miesięcy. 2732 Jednakże dzięki nowoczesnym metodom leczenia czas przeżycia uległ znacznej poprawie w ostatnich latach. 8
Obecnie dla pacjentów z przerzutami do mózgu z raka piersi średni czas przeżycia wynosi około 2 lat, a w przypadku pacjentów z HER2-dodatnim rakiem piersi nawet do 3 lat. 33 W przypadku pacjentów z rakiem płuca i przerzutami do mózgu mediana przeżycia wynosi około 12 miesięcy. 20
U pacjentów z korzystnymi czynnikami prognostycznymi, takimi jak młodszy wiek, dobry stan ogólny, brak przerzutów pozamózgowych i pojedynczy przerzut do mózgu, mediana przeżycia może wynosić nawet 13,5 miesiąca. 27
Warto podkreślić, że większość pacjentów z przerzutami do mózgu nie umiera z powodu samych przerzutów mózgowych, ale z powodu progresji choroby podstawowej w innych narządach. 2
Wpływ leczenia na progresję
Odpowiednie leczenie może znacząco wpłynąć na przebieg choroby i jakość życia pacjentów z przerzutami do mózgu:
- Radioterapia całego mózgu – poprawia objawy u 70-90% pacjentów, choć nawroty są częste i kontrola przerzutów może wystąpić tylko u połowy pacjentów. 17
- Radiochirurgia stereotaktyczna – może opóźnić progresję wewnątrzczaszkową. W badaniu METIS u pacjentów leczonych polami elektrycznymi (TTFields) i opieką wspomagającą mediana czasu do progresji wewnątrzczaszkowej wynosiła 21,9 miesiąca w porównaniu do 11,3 miesiąca u pacjentów otrzymujących wyłącznie opiekę wspomagającą. 34
- Leczenie systemowe – nowe terapie systemowe, które przenikają barierę krew-mózg, mogą powstrzymać progresję guza i zapobiec nowym przerzutom. 3536
- Leczenie chirurgiczne – może zmniejszyć objawy poprzez zmniejszenie ciśnienia śródczaszkowego. 3738
- Leczenie wspomagające – sterydy mogą zmniejszyć obrzęk mózgu i złagodzić objawy, leki przeciwpadaczkowe mogą kontrolować napady drgawkowe. 2439
Istotna jest też opieka paliatywna, która ma kluczowe znaczenie w łagodzeniu objawów i poprawie jakości życia pacjentów z przerzutami do mózgu, szczególnie w zaawansowanych stadiach choroby. 3340
Monitorowanie progresji
Ze względu na ryzyko nawrotu przerzutów do mózgu, nawet po skutecznym leczeniu, ważne jest regularne monitorowanie pacjentów za pomocą badań obrazowych. 24 U niektórych pacjentów z wysokim ryzykiem rozwoju przerzutów do mózgu, takich jak osoby z zaawansowanym rakiem nerki, zaleca się wykonywanie regularnych badań MRI mózgu, nawet przy braku objawów. 41
Wczesne wykrycie przerzutów do mózgu, zanim spowodują one objawy, jest kluczowe dla zwiększenia skuteczności leczenia. 41 Jak stwierdził dr Eric Jonasch z MD Anderson Cancer Center: „Kiedy [przerzuty] są małe, są stosunkowo łatwe do leczenia… ale kiedy stają się większe, wtedy stają się większym problemem do zarządzania. Dlatego tak ważne jest ich znalezienie – nawet jeśli nie powodują objawów – znalezienie ich wcześnie jest ważne.” 41
Podsumowując, przerzuty do mózgu powodują różnorodne objawy, które postępują w czasie i znacząco wpływają na jakość życia pacjentów. Wczesne rozpoznanie i odpowiednie leczenie może złagodzić objawy, spowolnić progresję choroby i wydłużyć życie pacjentów. Kluczowe znaczenie ma multidyscyplinarne podejście do leczenia oraz regularne monitorowanie pacjentów, nawet po skutecznym leczeniu początkowym.

- #1 Brain metastases – Symptoms and causes – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/brain-metastases/symptoms-causes/syc-20350136
Brain metastases may form one or more tumors in the brain. As they grow, they put pressure on surrounding brain tissue. This can cause symptoms such as headache, personality changes, confusion, seizures, vision changes, trouble speaking, numbness, weakness or loss of balance. […] Symptoms caused by brain metastases can vary. They depend on location, size and how fast they’re growing. […] Symptoms of brain metastases include: Headache, sometimes with vomiting or nausea. Mental changes, such as increasing memory problems. Seizures. Weakness or numbness on one side of the body. Vision changes. Difficulty speaking or understanding language. Loss of balance.
- #2 Brain Metastases: When Cancer Spreads to the Brainhttps://my.clevelandclinic.org/health/diseases/17225-metastatic-brain-tumors
Brain metastasis symptoms vary based on the tumors location and how its impacting your brain function in that area. The most common symptoms include: […] As brain metastases progress, you may notice new symptoms, including: […] Sometimes, brain metastases cause a stroke. But while stroke symptoms come on suddenly, most metastatic brain tumor symptoms come on slowly and worsen over time. […] Brain metastases are often curable. But even when theres no cure, treatments can help you live longer and improve your quality of life. The life expectancy associated with brain metastases was once less than six months. But new treatments have extended the timeline so that most people with this diagnosis are living longer and with much better symptom management. In fact, most people with brain metastases dont die from their brain tumor(s). […] Still, many of the questions that most people with brain metastases have like how fast their tumor will grow are highly individual. Your experience depends on the primary cancer, how many tumors you have and how you respond to treatment, among other things.
- #3 8 Top Brain Metastases Symptoms & Signs | MD Anderson Cancer Centerhttps://www.mdanderson.org/cancer-types/brain-metastases/brain-metastases-symptoms.html
The symptoms caused by a brain metastasis depend on the tumors location. For instance, a metastasis in a section of the brain that manages visual processing may cause vision problems. […] common brain metastasis symptoms include: […] Headaches: These are often the first symptoms of a brain metastasis. They are caused by the tumor putting pressure on the brain and skull. A headache caused by brain metastases usually becomes progressively worse as time passes. It may not get better with over-the-counter pain medicine and it may be associated with nausea or vomiting. It can get worse when you lie down, bend over or bear down, such as when you have a bowel movement. […] Seizures: Seizures can take many different forms, such as episodes of numbness, tingling, uncontrollable arm and leg movements, difficulty speaking, strange smells or sensations, staring and unresponsive episodes or convulsions.
- #4 Signs & Symptoms of Brain Metastases | Memorial Sloan Kettering Cancer Centerhttps://www.mskcc.org/cancer-care/types/brain-tumors-metastatic/symptoms
The symptoms and signs of brain metastases can be hard to see at first. We often find these tumors when we are testing you for other health conditions. We also find them when we are assessing the stage of your primary cancer. […] Your symptoms usually depend on the tumors location and size. Possible symptoms include: […] A tumor makes pressure inside the skull, squeezing nearby brain tissue. This causes headaches. They are often worse in the morning and hurt less as the day goes on. […] Brain metastases put pressure on the brain. This can cause nausea (feeling like throwing up) and vomiting (throwing up). […] A tumor affects the flow of electrical impulses through the brain. A seizure is sudden, uncontrolled change in your brain electrical activity. A partial seizure affects one area of your brain.
- #5 Brain metastases | Canadian Cancer Societyhttps://cancer.ca/en/cancer-information/cancer-types/metastatic/brain-metastases
Cancer that starts in one part of the body and spreads to the brain is called brain metastases. It’s sometimes called a metastatic brain tumour. Brain metastases are much more common than primary brain cancer. […] The most common symptom of brain metastases is a headache. Headaches may be caused by a tumour pressing on the brain, swelling caused by a fluid buildup around the brain (called edema), bleeding or hydrocephalus. […] Other signs and symptoms of brain metastases include: seizure, nausea and vomiting, weakness or numbness in parts of the body, such as the face, arms or legs, confusion and problems with memory, changes in behaviour and personality, problems with balance and coordination, loss of bladder or bowel control (called incontinence), problems with speech, problems with swallowing.
- #6 Metastatic Brain Tumors – AANShttp://www.aans.org/patients/conditions-treatments/metastatic-brain-tumors/
Tumors that spread to the brain from a primary neoplasm located in other organs of the body are referred to as metastatic brain tumors. They are among the most common intracranial brain tumors encountered by physicians. These tumors are a common complication of systemic cancers and an important cause of morbidity (rate of disease) and mortality (death) in patients. […] Approximately 200,000 new cases of brain metastases are diagnosed in the U.S. each year, and the number may be growing with increased awareness and improved diagnostic techniques. […] Besides the following symptoms, many patients may experience additional complications caused by the original tumor and its related manifestations. Increased Intracranial Pressure (ICP): In most patients, symptoms of brain metastases are caused by the expansion of lesions and increased ICP. The most common symptoms of increased ICP are headache, vomiting and disturbance of consciousness. Headache is the initial symptom in about half of brain tumor patients and is eventually experienced by the majority, at some point. Vomiting is an occasional accompaniment to the headache. It is far more common in children than in adults. In children, vomiting may be especially dramatic or forceful, so much so that it may be labeled as projectile in nature. Alteration in Consciousness: Patients at some point commonly experience alterations in consciousness, including both the level of consciousness and/or its quality. A brain tumor can induce a wide spectrum of changes in mental status, ranging from subtle alterations in personality to states of profound and irretrievable coma. Seizures (Epileptic Seizures/Fits): Seizures are associated with brain tumors in almost 35 percent of patients. Age increases the risk of epilepsy caused by a tumor especially in individuals beyond 45 years of age. Focal (Specific) Neurological Symptoms: Whereas headaches, altered mental status and seizures may be seen with tumors that occur in many parts of the brain, some symptoms are associated with tumors that occur in specific locations. These focal neurological symptoms affect the side of the body opposite from the side where the tumor resides and may include different modalities of sensation such as tingling and motor changes (hemiparesis).

Changes in mental function, mood or personality: You may become withdrawn, moody or inefficient at work. You may feel drowsy, confused and unable to think. Depression and anxiety, especially if either develops suddenly, may be an early symptom of a brain tumor. You may become uninhibited or behave in ways you never have before. […] Speech problems: Issues can include trouble finding words, talking incoherently and an inability to express or understand language. […] Changes in the senses: Brain metastases can impact your ability to hear, smell or see. This can include double vision or blurred vision. […] Changes in the sense of touch: Your ability to feel heat, cold, pressure, a light touch or sharp objects may change. […] Loss of balance or coordination. […] Changes in pulse or breathing rates: This symptom is caused by the tumor pressing against the brainstem.
- #8 Brain metastases: Symptoms, prognosis, diagnosis, and morehttps://www.medicalnewstoday.com/articles/brain-metastases
Brain metastases happen when cancer spreads from one area of the body to the brain. About 20% of people with cancer develop brain metastases. This can affect a persons outlook. […] Symptoms of brain metastases vary depending on many factors, including how big the tumor or tumors are and where they are in the brain. […] Some symptoms that may develop include: a chronic or intense headache, trouble moving one part of the body, numbness or tingling, confusion or problems with attention, changes in behavior or emotions, seizures, nausea or vomiting. […] Metastatic brain cancer is usually terminal. While some people are able to live longer than others and while a few survive much longer than average, most people have months to live by the time they receive a diagnosis. […] A 2018 study involving 145 people with brain metastases found that most died within 1 year of diagnosis. […] Even if a surgeon removes tumors from the brain, it is common for them to come back. […] Survival rates for metastatic brain cancer have improved considerably over the last 3 decades due to technologies such as whole brain radiation.
- #9 Signs & Symptoms of Brain Metastases | Memorial Sloan Kettering Cancer Centerhttps://www.mskcc.org/cancer-care/types/brain-tumors-metastatic/symptoms
A tumor can affect the parts of the brain that control speech, vision, and understanding. […] A tumor can affect the parts of the brain that control the muscles. This can cause weakness and numbness. You may have problems with movement and other motor functions. This happens if a tumor gets in the way of the normal flow of signals from the brain to muscles.
- #10 Stage 4 Metastatic Brain Cancer: Symptoms & Treatmenthttps://www.cancercenter.com/cancer-types/brain-cancer/types/metastatic-brain-cancer
Brain metastases are the most common type of brain tumor, accounting for between 98,000 and 170,000 cases annually in the United States. […] Patients with brain metastases may experience symptoms such as: Seizures, Numbness or tingling, Headaches, Changes in speech, Changes in coordination or balance, Altered mood, mental acuity or behavior, Blurred or double vision, Sharper or duller senses, such as hearing or smelling, Weakness affecting one side of the body. […] Cancer patients who experience any of these symptoms should contact their care team right away to evaluate the cause.
- #11 Final Stages of Brain Cancer Metastasis – Symptoms of the Last Stage of Brain Cancerhttps://massivebio.com/final-stages-of-brain-cancer-metastasis/
Final stages of brain cancer metastasis often result in increased symptoms and complexities in patient care. The spread of cancer cells to other parts of the brain and other organs leads to a significant escalation in both the number and severity of symptoms. Treatment strategies at this stage focus on symptom management and maintaining quality of life. […] Final stage brain cancer presents a range of symptoms that significantly affect a patients quality of life and neurological functions. The specific symptoms experienced can vary, particularly influenced by the tumors location, such as the Temporal lobe or Occipital lobe. Below are the key symptoms associated with the final stages of this disease: Changes in vision: Tumors in the occipital lobe often lead to vision problems, such as blurred vision and difficulties with visual perception. Memory loss and confusion: Impairments in memory and understanding, caused by tumors affecting the temporal lobe, are common, manifesting as forgetfulness and confusion. Cognitive and behavioral changes: Tumors can cause shifts in personality and behavior, including mood swings and changes in social behavior. Physical Weakness: A general decline in physical strength and coordination makes daily tasks challenging.
- #12 Final Stages of Brain Cancer Metastasis – Symptoms of the Last Stage of Brain Cancerhttps://massivebio.com/final-stages-of-brain-cancer-metastasis/
End-stage brain cancer significantly impacts survival rate and life expectancy. As the disease progresses, these rates generally decrease, reflecting the advanced and aggressive nature of the cancer. Effective palliative care is crucial to manage symptoms and provide the best quality of life possible under these circumstances. […] The brain metastases generally begin subtly but grow increasingly disruptive. Cerebral metastases profoundly affect cognitive and sensory capabilities, notably in the parietal lobe and temporal lobe. The parietal lobes damage leads to issues with spatial orientation and sensory perception, while deterioration in the temporal lobe disrupts memory and language processing. […] As the cancer progresses to the right cerebellar area, it severely impairs balance and motor control. This deterioration manifests as increased instability and a dramatic decline in physical activity, significantly affecting the patients quality of life.
- #13 Final Stages of Brain Cancer Metastasis – Symptoms of the Last Stage of Brain Cancerhttps://massivebio.com/final-stages-of-brain-cancer-metastasis/
The life expectancy of someone with brain cancer metastasis is influenced by numerous factors, including the origin of the cancer, the location of the metastasis in the brain, and the effectiveness of the treatment. Metastatic brain cancer occurs when cancer cells from another part of the body, such as the lung, spread to the brain. These metastatic cells can travel to various regions of the brain, including the parietal lobe, which is responsible for functions such as movement and sensation. When the cancer affects this area, patients may experience weakness, difficulty with coordination, or even issues with language. […] In conclusion, brain metastasis represents a serious complication, with the specific prognosis dependent on the cancer type, the location of brain metastasis, and available treatment options.
- #14 Brain Metastases Symptoms | Expert Surgeon | Aaron Cohen-Gadol, MDhttps://www.aaroncohen-gadol.com/en/patients/brain-metastasis/types/symptoms
Increased intracranial pressure due to brain metastases can lead to nausea and vomiting. These symptoms are often more severe in the morning and may be accompanied by other neurological signs. […] Some patients may exhibit personality changes, mood swings, or emotional instability. These changes can be distressing for both the patient and their loved ones. […] Brain metastases located in areas responsible for speech and language can lead to difficulties in speaking, understanding language, or finding the right words. […] Tumors affecting the cerebellum, a part of the brain responsible for coordination, can cause balance and gait issues. Cerebellar metastasis symptoms can be particularly noticeable or disrupting. […] In severe cases, brain metastases can lead to a decreased level of consciousness, including coma. This is a medical emergency requiring immediate attention.
- #15 Metastatic Brain Cancerhttps://www.rwjbh.org/treatment-care/neuroscience/neurosurgery/conditions-treated/brain-metastases/
Changes in mental function, mood, and personality: Those with brain metastases often cannot notice the gradual changes in their mental function, which may include depression, anxiety, drowsiness, confusion, and memory problems. It can be difficult to concentrate, and you may be inefficient at work. […] Seizures: These seizures are not always dramatic events with noticeable convulsions. Those who have seizures may experience episodes of staring while being unresponsive to stimuli, and you may notice numbness, tingling, a metallic taste, and other strange sensations. […] Speech difficulties: Expressing and understanding language may become more difficult, and you may have trouble finding words. […] Changes in pulse and/or breathing rates: This is caused by the tumor pressing against your brainstem.
- #16 8 Top Brain Metastases Symptoms & Signs | MD Anderson Cancer Centerhttps://www.mdanderson.org/cancer-types/brain-metastases/brain-metastases-symptoms.html
In addition, brain metastases can harm the brain by: […] Invading and destroying brain tissue. […] Putting pressure on nearby tissue. […] Taking up space and increasing pressure within the skull (intracranial pressure). […] Causing fluid to build-up in the brain. […] Blocking normal circulation of cerebrospinal fluid through the spaces within the brain. […] Causing bleeding in the brain.
- #17 Brain Metastases: Staging and Treatment | OncoLinkhttps://www.oncolink.org/cancers/brain-tumors/brain-metastasis/brain-metastases-staging-and-treatment
Brain metastases take up space in the brain, putting pressure on nearby tissue. This pressure can cause symptoms. […] WBRT improves symptoms of brain metastases in 70-90% of patients, although some of this is also a result of the corticosteroids. Recurrence is common, and control of brain metastases may only happen in half of the patients. […] Patients with tumors that are more sensitive to the effects of radiation respond better (lung and breast, for example) than those with tumors that are less sensitive to radiation (melanoma and renal cancers).
- #18 Diagnosing Metastatic Brain Tumors | NYU Langone Healthhttps://nyulangone.org/conditions/metastatic-brain-tumors/diagnosis
A metastatic brain tumor is cancer that has spread to the brain from another part of the body. These tumors which are also called brain metastases are malignant, meaning they can spread throughout the body. […] Symptoms of brain metastases, which may develop gradually or rapidly, depend on the tumors size and location. They may include headache, weakness on one side of the body, seizures, vision changes, memory loss, or problems with balance and walking. A growing tumor often has fluid buildup, called edema, around it. Edema puts pressure on the brain and may damage the organ or be fatal.
- #19 Brain Metastasis Clinical Presentation: History, Physicalhttps://emedicine.medscape.com/article/1157902-clinical
Headache (42%) and seizure (21%) are the 2 most common presenting symptoms. […] New onset of seizures in a patient older than 35 years is highly suggestive of primary or metastatic disease. […] In addition, 35% of patients have cognitive dysfunction, and 30% have motor dysfunction. […] About 10% of patients present with hemorrhage. Metastases commonly derive from choriocarcinoma, melanoma, bronchogenic carcinoma, thyroid carcinoma, and renal carcinoma bleeding; most of these hemorrhages are intramural.
- #20 Signs Lung Cancer Has Spread to Your Brainhttps://www.webmd.com/lung-cancer/signs-lung-cancer-spread-brain
If lung cancer isnt caught early, theres a high risk of it spreading to other parts of your body, including the brain. […] This can cause one or more tumors to form in the brain, which can lead to serious symptoms like blurry vision, slurred speech, headaches, and seizures. […] About 50% of those who have lung cancer will develop brain mets. And around 25% already have them at the time of diagnosis. […] The median survival of people with lung cancer and brain mets is about 12 months. […] Symptoms related to brain mets depend on the location and size of the tumors in the brain. Symptoms also reflect how quickly a tumor is growing and if there is actual increased pressure within the brain. […] Focal symptoms result from direct pressure or destruction locally in the brain. […] Global symptoms include headaches, confusion or memory problems, nausea and vomiting, and personality changes. […] The symptoms may suddenly change if you have a bleed (hemorrhagic stroke) from the tumor. […] If your lung cancer spreads to the brain, research shows that the outlook is poor. On average, those who develop brain mets tend to live for less than 6 months after diagnosis.
- #21 Metastatic Brain Tumors – Harvard Healthhttps://www.health.harvard.edu/cancer/metastatic-brain-tumors-a-to-z
A metastatic brain tumor is cancer that has spread (metastasized) from another part of the body to the brain. […] The signs and symptoms of secondary brain tumors depend on their size and location. This is because different parts of the brain control different functions. […] Signs and symptoms of brain metastases include headaches, seizures, visual changes, such as double vision, lack of energy and/or sleepiness, vomiting, changes in mood, behavior, or personality, weakness in parts of the body, trouble speaking or hearing, problems with memory or mental ability, loss of balance or coordination. […] Some people with metastatic brain tumors don’t show any symptoms. However, over time, the brain metastases will continue to grow, eventually causing symptoms. […] Primary cancers spread to the brain at different rates. For example, lung cancer tends to spread to the brain much sooner than many other cancers. The tumors will continue to grow until they are treated. […] The outlook for patients with brain metastases depends on the patient’s age, the number and location of the tumors, how well the tumors respond to treatment, whether the primary tumor is still growing and spreading.

Brain metastases develop most often in people with lung cancer, breast cancer, and melanoma, but also with other types of cancer. Brain metastases can be found at the same time as the primary cancer or later. […] Symptoms of brain metastases depend on the location, size and number of growths in the brain, or the amount of swelling. Metastases can push on or cause swelling in specific areas causing specific symptoms. Not everyone with a brain metastasis will have symptoms but most do. […] The most common symptoms are: Headache, Not being able to move parts of your body, like an arm or leg, Sleepiness, Memory problems, Changes in emotions or how a person acts, Problems hearing, seeing, or swallowing, Seizures, Nausea or vomiting.

Brain metastases can affect nearly a third of patients with metastatic HER2-positive breast cancer, a type of breast cancer that expresses a high level of HER2 proteins. […] Research showing new treatments have stopped progression in the brain and even prevented new metastases have created more options for treating patients with brain metastases and allowed for broader clinical trial criteria that include patients with brain metastases. […] Local therapy is very much a key element or the key element for brain metastases in part because of how effective these treatments are, with radiation and surgery, and also in recognition of how important the functional consequences of unrelenting brain metastases are. […] But management of brain metastases has evolved in what Dent called a watershed moment as researchers discover systemic therapies that penetrate the blood-brain barrier and ward off tumor progression.

- #26 Metastatic Brain Tumors – AANShttp://www.aans.org/patients/conditions-treatments/metastatic-brain-tumors/
Many people with metastatic brain tumors have widespread tumor metastasis. The effectiveness of treatment of brain metastases is almost always determined by how well the primary cancer is controlled. In the absence of control of the primary cancer, treatment of metastatic brain tumors would be a futile endeavor. The prognostic factors are complex and largely depend upon the status of systemic disease, extent of neurological deficit, length of time between first diagnosis of cancer and the diagnosis of brain metastasis, the type of primary tumor and the nature, size and invasiveness of the metastatic lesion, among other things. Hence, careful coordination and communication between the neurosurgeon, radiation oncologist and primary oncologist is essential. Relapse of disease either in the brain or the body is common and hence, frequent and consistent follow-up with imaging studies is also essential.
- #27 Brain metastasis – Wikipediahttps://en.wikipedia.org/wiki/Brain_metastasis
The prognosis for brain metastases is variable; it depends on the type of primary cancer, the age of the patient, the absence or presence of extracranial metastases, and the number of metastatic sites in the brain. For patients who do not undergo treatment the average survival is between one and two months. However, in some patients, such as those with no extracranial metastases, those who are younger than 65, and those with a single site of metastasis in the brain only, prognosis is much better, with median survival rates of up to 13.5 months. […] Brain metastases are most commonly diagnosed within multiple intracranial areas within the context of extracranial diseases.

Having a clear prognosis for patients with brain metastases allows health care practitioners (HCPs) to determine appropriate palliative management and assist patients when making informed treatment decisions. […] Fatigue, headaches, and focal weakness are the most prevalent symptoms, although other symptoms can include seizures and visual impairments. […] The most common symptom changes following whole brain radiotherapy (WBRT) were: worsened fatigue, appetite loss, and weakness. Worsened difficulty concentrating, fatigue, nausea and headaches were most predictive of a poorer survival outcome. […] HCPs should be aware of the shorter prognosis associated with patients exhibiting one or more of these symptoms and tailor care accordingly to maximize patients remaining quality of life (QOL).

In particular, individuals scoring with moderate to severe fatigue and appetite loss had shorter survival than those presenting with mild or no symptoms. […] Greater burden of appetite loss, headache, and difficulty concentrating were also correlated with shorter OS. As time progressed, increased concentration difficulties, issues with balance, and fatigue intensity were associated with higher risk of death. […] Patients with increased concentration difficulty had higher risk of impending death compared to patients with no change or with decreased scores. […] For month 2, symptom change of fatigue was significantly related to OS. Patients with increased experience of fatigue had shorter survival compared to patients with decreased score. […] For month 3, three symptom changes were significantly related to OS: nausea, appetite loss, and concentration difficulty. Patients with increased nausea had higher risk of impending death comparing to patients with decreased score.

A build-up of pressure in the brain, caused by areas of secondary breast cancer, can lead to headaches. These might be different to headaches you’ve had before. They may get worse, continue for days or not go away completely. […] Cancer-related fatigue is 1 of the most common symptoms in people with secondary breast cancer. Fatigue is extreme tiredness that does not go away with rest or sleep. It has many causes, from the emotional impact of a diagnosis to side effects of treatment or growth and spread of the cancer.
- #31 Recognizing the Symptoms of Terminal Brain Cancer – Ezrahttps://ezra.com/blog/recognizing-the-symptoms-of-terminal-brain-cancer
End-stage brain cancer symptoms are typically similar to Stage 3, however, with worsening effects on the body and brain. […] Cognitive decline is a hallmark symptom of terminal brain cancer, significantly impacting patients daily lives. Common cognitive symptoms include memory loss, confusion, difficulty concentrating, impaired problem-solving, and language difficulties. These symptoms can profoundly affect a patients ability to perform daily activities. […] Increasing from stage 3, personality changes, mood disturbances, and behavioural shifts become more common as the tumor affects different brain regions. These changes can be distressing for both patients and families. […] As terminal brain cancer progresses, patients often develop speech and swallowing problems. Speech difficulties can range from slurred speech to complete inability to communicate verbally, depending on the affected brain areas. Swallowing issues (dysphagia) are common, especially in end-stage brain cancer, making eating and drinking challenging and increasing the risk of aspiration. […] The timeline for progression and survival rates for stage 4 brain cancer varies based on tumor type, patient age, overall health, and whether treatment is pursued. […] Symptoms worsen quickly, with rapid decline in mobility, cognition, and overall well-being.

Brain metastases are estimated to account for approximately 25-50% of intracranial tumors in hospitalized patients. […] These patients can commonly present with headaches, seizures, mental status alterations, ataxia, nausea and vomiting, and visual disturbances. However, up to 60-75% of patients can be asymptomatic at the time of imaging. […] Overall patients with brain metastases typically have a mean survival of one month without treatment. With treatment, survival improves, but it is still dismal. The mean age of survival is still less than one year, although in some patients with solitary metastases, longer survival is encountered.

The prognosis of patients with breast cancer who develop brain metastasis has substantially improved over the past 20 years, but can vary widely depending upon your breast cancer subtype and your age. […] Historically, survival of patients with breast cancer brain metastasis was very poor, ranging from 3-6 months. However, with the development of new treatments that effectively control cancer outside of the brain, patients with BCBM are living longer. The overall survival for breast cancer patients with brain metastasis (all types combined) is now closer to just over 2 years, with a life expectancy of 3 years for those with HER2+ tumors. […] Studies have also shown that specialized care known as palliative or supportive care, which addresses the symptoms and stress of an advanced disease, can improve quality of life. In some cases, it can even extend survival. For patients with brain metastasis, palliative radiation therapy is often prescribed to control tumors or relieve symptoms such as headaches. […] Treatment options for breast cancer patients with brain metastasis often include oral or IV medication, surgery, stereotactic radiosurgery, whole-brain radiation therapy or some combination of these.

Findings from the phase 3 METIS trial found that tumor-treating fields were able to significantly improve time to intracranial progression in patients with brain metastases from non-small cell lung cancer. […] Adult patients with brain metastases from non-small cell lung cancer (NSCLC) treated with tumor-treating fields (TTFields) plus supportive care experienced a significant improvement in time to intracranial progression, meeting the primary end point of the phase 3 METIS trial (NCT02831959). […] With a median treatment duration of 16 weeks, patients who were treated with TTFields and supportive care had a median time to intracranial progression of 21.9 months vs 11.3 months for patients treated with supportive care alone (n = 298; HR, 0.67; P =.016). […] In this international, multicenter, phase 3 trial, the use of TTFields therapy significantly delayed time to brain relapse, with associated improvement in quality of life and stable cognition. This is a major benefit and is potentially practice changing.

The role of surgery in the management of brain metastases has grown over time and is now considered the standard care for select patients. […] Advances in radiotherapy and systemic therapy have led to an expanded role for surgery in patients with multiple brain metastases and created a new indication for surgery in patients with symptomatic brain metastases: resection to reduce steroid dependence. […] Radiation therapy is the mainstay of treatment of intracranial metastases to attain local control and prevent growth and recurrence. […] Stereotactic radiosurgery (SRS) has emerged as a favorable alternative to WBRT in many patients with brain metastases. […] The nature of metastatic cancer renders each patient with brain metastases unique, and therefore no single treatment paradigm is appropriate for every such patient.

- #41 Brain Metastasis: Recognizing Symptoms Early Can Help – Kidney Cancer Associationhttps://www.kidneycancer.org/brain-metastasis-recognizing-symptoms-early-can-help/
About 15% of people with advanced RCC will develop brain tumors, and the prognosis for such cases is generally poor. People with brain tumors from RCC may experience dizziness, headaches, nausea, and other neurological symptoms. […] Finding brain tumors earlyâeven before people become symptomaticâis key to increasing responsiveness to therapy, according to Dr. Eric Jonasch, a medical oncologist and kidney cancer expert at MD Anderson Cancer Center. […] When theyâre small, theyâre actually fairly easy to treat . . . but when they get bigger, then they become a bigger problem to manage. So thatâs why finding themâeven if theyâre not symptomaticâfinding them early is important, said Jonasch. […] People diagnosed with metastatic RCC should receive an initial MRI of the brain plus a repeat scan once a year, advised Jonasch.
