Nowotwór rdzenia kręgowego
Etiologia i przyczyny
Nowotwory rdzenia kręgowego dzielą się na pierwotne, rozwijające się bezpośrednio w rdzeniu lub jego otoczeniu, oraz wtórne, będące przerzutami z innych lokalizacji, takich jak rak piersi, płuc, prostaty, nerki, tarczycy, szpiczak mnogi, chłoniaki, białaczki i czerniak. Patogeneza pierwotnych guzów rdzenia opiera się na mutacjach genetycznych, które prowadzą do niekontrolowanego wzrostu komórek, z udziałem genów regulujących różnicowanie komórek glejowych, np. nadekspresji genów HOX i IGF1 w wyściółczakach. Znaczącą rolę odgrywają także dziedziczne zespoły genetyczne, takie jak neurofibromatoza typu 1 (mutacja genu supresorowego na chromosomie 17, 19% pacjentów rozwija guzy rdzenia), neurofibromatoza typu 2 (mutacja białka merliny na chromosomie 22, 2% pacjentów z guzami wewnątrzrdzeniowymi) oraz choroba von Hippla-Lindaua, związana z mutacją genu vhl i występowaniem naczyniaków krwionośnych. Glejaki stanowią około 80% guzów wewnątrzrdzeniowych, z przewagą gwiaździaków u dzieci i wyściółczaków u dorosłych, a naczyniaki krwionośne powstają z prekursorów erytrocytów. Ekspozycja na promieniowanie jonizujące, zwłaszcza po radioterapii w młodym wieku, oraz kontakt z pestycydami i chemikaliami przemysłowymi zwiększają ryzyko rozwoju tych nowotworów.

Etiologia nowotworów rdzenia kręgowego
Nowotwory rdzenia kręgowego to nieprawidłowe skupiska komórek, które rozwijają się w obrębie rdzenia kręgowego lub w jego otoczeniu. Mogą one być pierwotne (powstające bezpośrednio w rdzeniu) lub wtórne (przerzutowe). Dokładne przyczyny powstawania tych guzów, szczególnie pierwotnych, nie są w pełni poznane, chociaż badacze zidentyfikowali pewne czynniki ryzyka i potencjalne mechanizmy ich rozwoju.123
Mutacje genetyczne i zmiany w DNA
Główną przyczyną rozwoju nowotworów rdzenia kręgowego są zmiany w DNA komórek. Nowotwór rdzenia kręgowego rozpoczyna się, gdy komórki w rdzeniu kręgowym lub w tkance otaczającej rdzeń rozwijają zmiany w swoim materiale genetycznym. W komórkach nowotworowych zmiany w DNA prowadzą do odmiennych instrukcji dla komórek, które nakazują im szybki wzrost i namnażanie się. Czasami komórki rozwijają zmiany w DNA, które przekształcają je w komórki nowotworowe.123
Większość mutacji genetycznych związanych z nowotworami rdzenia kręgowego występuje przypadkowo i nie jest dziedziczna. Są to prawdopodobnie losowe zdarzenia, które czasem zachodzą wewnątrz komórki, bez wyraźnej przyczyny zewnętrznej. Badania sugerują, że geny regulujące różnicowanie komórek glejowych odgrywają rolę w patogenezie molekularnej. Na przykład w przypadku wyściółczaków rdzeniowych zaobserwowano nadekspresję genów z rodziny HOX oraz insulinopodobnego czynnika wzrostu 1 (IGF1).12
Czynniki genetyczne i choroby dziedziczne
Chociaż większość nowotworów rdzenia kręgowego występuje sporadycznie, niektóre są związane z określonymi zespołami klinicznymi i chorobami genetycznymi. Najważniejsze z nich to:123
- Neurofibromatosis typu 1 (NF1) – spowodowana mutacją na chromosomie 17, która koduje gen supresorowy nowofibrominę. Około 19% pacjentów z NF1 rozwija guzy rdzenia kręgowego, głównie nerwiaki i guzy zewnątrzrdzeniowe.
- Neurofibromatosis typu 2 (NF2) – spowodowana mutacją białka supresorowego schwannominy/merliny na chromosomie 22. Stwierdza się ją u około 2% pacjentów z guzami wewnątrzrdzeniowymi. Pacjenci z NF2 częściej mają wyściółczaki, a czasami oponiaki.
- Choroba von Hippla-Lindaua – związana głównie z naczyniakami krwionośnymi jako najczęstszymi guzami wewnątrzrdzeniowymi. Jest to rzadkie, wieloukładowe zaburzenie związane z łagodnymi guzami naczyniowymi (naczyniakami krwionośnymi) w mózgu, siatkówce i rdzeniu kręgowym oraz z innymi rodzajami guzów w nerkach lub nadnerczach.
Wymienione choroby genetyczne są dziedziczone w sposób autosomalny dominujący, co oznacza, że osoby dotknięte chorobą mają 50% szans na przekazanie zmutowanego genu swoim dzieciom.1
Nowotwory przerzutowe i wtórne
Większość nowotworów rdzenia kręgowego stanowią guzy wtórne (przerzutowe), które rozprzestrzeniły się do rdzenia kręgowego z innego miejsca w organizmie. Nowotwory, które najczęściej dają przerzuty do rdzenia kręgowego, to:123
- Rak piersi
- Rak płuc
- Rak prostaty
- Rak nerki
- Rak tarczycy
- Szpiczak mnogi
- Chłoniaki i białaczki
- Czerniak
Przerzuty najczęściej rozwijają się, gdy komórki nowotworowe odrywają się od głównego guza i przedostają do krwiobiegu lub układu limfatycznego. Te układy transportują płyny po całym ciele, co umożliwia rozprzestrzenianie się komórek nowotworowych z jednego obszaru ciała do innego. Ponieważ rdzeń kręgowy ma znaczne zaopatrzenie w krew i znajduje się w pobliżu układów limfatycznych i żylnych, jest on szczególnie narażony na przerzuty.12
Komórkowe pochodzenie guzów rdzenia
Większość wewnątrzrdzeniowych guzów rdzenia kręgowego to glejaki (około 80%), które można podzielić na gwiaździaki i wyściółczaki. Gwiaździaki są częstsze u dzieci z guzami wewnątrzrdzeniowymi, natomiast wyściółczaki częściej występują u dorosłych.1
Identyfikacja mitotycznie aktywnych komórek macierzystych układu nerwowego i komórek progenitorowych w całym ośrodkowym układzie nerwowym zmieniła sposób myślenia o powstawaniu guzów wewnętrznych OUN. Wiele dowodów wskazuje na komórki macierzyste układu nerwowego jako komórki pochodzenia guzów mózgu. W przypadku rdzenia kręgowego niektóre wstępne badania wykazały podobieństwa między komórkami nowotworowymi z wyściółczaków rdzenia kręgowego a komórkami macierzystymi rdzenia kręgowego.1
Naczyniak krwionośny, inny stosunkowo częsty rodzaj guza wewnątrzrdzeniowego, powstaje z prekursorów czerwonych krwinek. Guzy te są często anatomicznie wewnątrzrdzeniowe ze względu na ich związek z naczyniami krwionośnymi, które przenikają i odżywiają rdzeń kręgowy. Występują one w wyniku mutacji w genie supresorowym guza zwanym vhl, który został zidentyfikowany jako zmieniony u pacjentów z chorobą von Hippla-Lindaua.1
Narażenie na promieniowanie i czynniki środowiskowe
Ekspozycja na promieniowanie jonizujące jest jednym z niewielu potwierdzonych czynników ryzyka rozwoju nowotworów rdzenia kręgowego. Osoby, które w przeszłości otrzymywały radioterapię, szczególnie w młodym wieku, mogą być bardziej narażone na rozwój tych guzów. Nowotwory związane z radioterapią są stosunkowo rzadkie, ale mogą wystąpić nawet kilkadziesiąt lat po leczeniu.123
Badania wskazują również na potencjalny związek między ekspozycją na określone chemikalia lub substancje rakotwórcze a rozwojem nowotworów rdzenia kręgowego. Do substancji tych mogą należeć:12
- Pestycydy i inne chemikalia rolnicze
- Przemysłowe chemikalia stosowane w budownictwie, tekstyliach i tworzywach sztucznych
- Inne substancje zanieczyszczające środowisko
Osłabiony układ odpornościowy
Osłabiony układ odpornościowy może zwiększać ryzyko rozwoju pewnych typów nowotworów rdzenia kręgowego, szczególnie chłoniaków rdzenia kręgowego. Chłoniaki rdzenia kręgowego są częstsze u osób z osłabionym układem odpornościowym, co może być spowodowane:123
- Infekcjami osłabiającymi odporność
- Chorobami autoimmunologicznymi
- Leczeniem immunosupresyjnym
- Przeszczepami narządów
Wiek i inne czynniki demograficzne
Nowotwory rdzenia kręgowego mogą wystąpić u osób w każdym wieku, ale ich częstotliwość różni się w zależności od wieku i typu guza. Ogólnie rzecz biorąc, ryzyko rozwoju nowotworów rdzenia kręgowego wzrasta wraz z wiekiem, a większość przypadków występuje u starszych dorosłych.12
Istnieją również pewne różnice w częstości występowania nowotworów rdzenia kręgowego w zależności od płci i pochodzenia etnicznego, chociaż wzorce te nie są tak wyraźne jak w przypadku niektórych innych nowotworów. Na przykład, niektóre badania sugerują, że biali mężczyźni są bardziej narażeni na rozwój guza OUN niż inne grupy demograficzne.1
Brak możliwości zapobiegania nowotworom rdzenia kręgowego
Obecnie nie istnieją znane metody zapobiegania nowotworom rdzenia kręgowego, szczególnie tym pierwotnym. Większość z nich pojawia się spontanicznie, bez wyraźnej przyczyny. W przypadku nowotworów wtórnych, zapobieganie i wczesne wykrywanie pierwotnego nowotworu może zmniejszyć ryzyko przerzutów do rdzenia kręgowego.12
Ważne jest, aby pamiętać, że nie ma żadnych znanych czynników związanych ze stylem życia czy środowiskiem, które byłyby wyraźnie powiązane z rozwojem pierwotnych nowotworów rdzenia kręgowego u dzieci czy dorosłych. W większości przypadków nie ma nic, co pacjenci lub rodzice mogliby zrobić, aby zapobiec tym nowotworom.12
Czynniki etiologiczne nowotworów rdzenia kręgowego
Podsumowując, do głównych przyczyn i czynników ryzyka nowotworów rdzenia kręgowego należą:1
- Przypadkowe mutacje genetyczne i zmiany w DNA
- Dziedziczne choroby genetyczne (neurofibromatoza typu 1 i 2, choroba von Hippla-Lindaua)
- Przerzuty z innych nowotworów (płuc, piersi, prostaty, nerki)
- Narażenie na promieniowanie, szczególnie w wyniku wcześniejszej radioterapii
- Ekspozycja na substancje chemiczne i rakotwórcze
- Osłabiony układ odpornościowy
- Wiek (zwiększone ryzyko u starszych dorosłych)
Pomimo zidentyfikowania tych czynników ryzyka, dokładne mechanizmy rozwoju nowotworów rdzenia kręgowego pozostają w dużej mierze nieznane. Badania nad etiologią tych guzów trwają, aby lepiej zrozumieć ich pochodzenie i opracować skuteczniejsze strategie diagnostyczne i terapeutyczne.12

It’s not clear what causes most spinal cord tumors. A spinal cord tumor starts as a growth of cells in or around the spinal cord. […] A spinal cord tumor starts when cells in the spinal cord or in the tissue around it develop changes in their DNA. […] In tumor cells, the DNA changes give different instructions. The changes tell the tumor cells to grow and multiply quickly. […] Sometimes the cells develop DNA changes that turn them into cancer cells.

Most gene changes are probably just random events that sometimes happen inside a cell, without having an outside cause. […] Other than radiation, there are no known lifestyle-related or environmental factors clearly linked to childhood brain tumors, so it’s important to remember that there is nothing these children or their parents could have done to prevent these cancers.
- #1 Intramedullary Spinal Cord Tumors – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK442031/
Although intramedullary spinal cord tumors are mostly sporadic, some are associated with clinical syndromes, such as neurofibromatosis 1 or 2 (NF-1, NF-2) and Von Hippel-Lindau disease. NF-1 is due to a mutation on chromosome 17, which encodes the tumor suppressor gene neurofibromin. About 19% of patients with NF-1 develop an intramedullary spinal cord tumor. NF-1 is largely associated with neurofibromas and intradural extramedullary-type spinal cord tumors. NF-2, caused by a mutation of the tumor suppressor protein schwannomin/merlin on chromosome 22, is reported in 2% of patients with intramedullary spinal cord tumors. Patients with NF-2 more commonly present with ependymomas and occasionally meningiomas (extramedullary). In Von Hippel-Lindau disease, hemangioblastomas are the most frequent intramedullary spinal cord tumors. Overall, astrocytomas are the most commonly encountered intramedullary spinal cord tumors. […] Approximately 80% of intramedullary spinal cord tumors are gliomas, which can be subdivided into astrocytomas and ependymomas. Astrocytomas are more common in children with intramedullary spinal cord tumors, whereas ependymomas are more often found in adults with intramedullary spinal cord tumors.

The exact spinal cord tumor itself cannot be inherited. However, in cases in which a known genetic disorder is involved, the gene mutation that contributed to its development might be passed down and increase the risk of a tumor forming on the spinal cord. The following are hereditary conditions known to be associated with spinal cord tumor development. […] These genetic conditions are inherited in an autosomal dominant manner, which means that affected people have a 50% chance of passing the mutated gene to their children. […] Unfortunately, spinal cord tumors cannot be prevented. They often occur spontaneously with no clear cause. However, there are certain steps that you can take to maintain overall health and potentially reduce the risk of some types of tumors in general. […] Primary tumors are thought to be caused by genetic mutations that lead to a dysfunction in cell growth, but the exact cause of such mutations is unclear. […] Certain hereditary conditions, such as NF1, NF2, and VHL disease, can lead to tumor growth in different areas of the body, including the spinal cord. […] There is currently no known method for preventing spinal cord tumors.
- #1 Spinal Tumors: Types, Causes, Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/17500-spinal-tumors
Spinal tumors can form anywhere in and along your spinal column, which includes your vertebrae, spinal cord and the tissues surrounding your spinal cord. Most spinal tumors result from cancer metastasis cancer that has spread from another area of your body to your spine. […] The cause of a spinal tumor depends on what type it is primary or secondary (metastatic). […] Scientists arent sure of the cause of most primary spinal tumors. Some of them may be caused by exposure to cancer-causing chemicals or substances. Spinal cord lymphomas (cancers that affect a type of immune cell) are more common in people with weakened immune systems. Spinal tumors can sometimes run in families, so scientists think theres likely a genetic component. […] By definition, secondary (metastatic) spinal tumors are caused by cancer that formed elsewhere in your body and spread (metastasized) to your spine.
- #1 Spinal Tumors: Symptoms & Causes | Och Spine at NewYork-Presbyterianhttps://www.nyp.org/ochspine/spinal-tumors/symptoms
Spinal tumors include benign (noncancerous) and malignant (cancerous) growths that can develop within the vertebrae (bones of the spine), next to the spinal column, or within the vertebral canal or the spinal cord. They may originate from the spine (primary tumors) or spread from another body part in people with cancer (secondary or metastatic tumors). […] There is no known direct cause of spinal tumors. Possible causes may differ depending on the type of tumor: […] Possible causes of primary tumors may include: […] Exposure to cancer-causing substances or chemicals […] Weakened immune system. Spinal cord lymphomas are more common in people who are immunocompromised […] Genetic defects. Defective genes may play a role, whether inherited or developed over time […] Secondary spinal tumors are caused by cancer cells spreading from another part of the body, often through the blood or lymphatic system. […] Types of cancer that commonly metastasize to the spine or spinal cord include: […] Breast cancer […] Lung cancer […] Colon cancer […] Lymphoma […] Melanoma […] Thyroid cancer […] Prostate cancer […] Kidney cancer.
- #1 Spinal Tumors: Types, Causes, Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/17500-spinal-tumors
Metastases most commonly develop when cancer cells break away from the main tumor and enter your bloodstream or lymphatic system. These systems carry fluids around your body, so they can carry cancer cells from one area of your body to another. […] Since your spine has a significant blood supply and is near lymphatic and venous drainage systems, its generally vulnerable to metastasis.
- #1 Intramedullary Spinal Cord Tumors: Practice Essentials, Epidemiology, Etiologyhttps://emedicine.medscape.com/article/251133-overview
Individuals with type I and type II neurofibromatosis (NF1 and NF2) have been recognized for some time as having an increased incidence of intramedullary spinal tumors, as well many other kinds of tumors, compared with the general population. This general predisposition to tumors has been linked to germline mutations in 2 different genes named for their associated diseases. Patients with the NF1 gene are predisposed to spinal astrocytomas, whereas patients with the NF2 gene are predisposed to spinal ependymomas. Genetic analyses of spinal ependymomas from individuals without syndromic neurofibromatosis have shown somatic mutations in the NF2 gene in a subset of cases. […] The identification of mitotically active neural stem cells and neural progenitor cells throughout the central nervous system has altered current thinking about how all intrinsic CNS tumors arise. Many lines of evidence point toward neural stem cells as the cells of origin in brain tumors. This line of inquiry is not nearly as advanced in the spinal cord, but some preliminary work has shown similarities between tumor cells from spinal ependymomas and neural stem cells from the spinal cord.

The other relatively common type of intramedullary spinal tumor is hemangioblastoma. Hemangioblastomas are thought to arise from red blood cell precursors and are not intrinsic spinal cord tumors, but they are often anatomically intramedullary because of their association with the blood vessels that penetrate and nourish the spinal cord. Hemangioblastomas occur as a result of mutations in a tumor suppressor gene called vhl, which was found to be altered in patients with the neurocutaneous disorder von Hippel-Lindau disease (VHL). Patients are predisposed to form hemangioblastomas in the brain and spinal cord, and somatic mutations in the vhl gene have been found in tumors from patients without syndromic VHL.

What causes brain and spinal cord tumors in children? […] Scientists are still trying to learn exactly why some cells grow, function, and die normally, while others grow abnormally and develop into a brain or spinal cord tumor. Brain and spinal cord tumors are most likely caused by mutations (random changes) in the DNA within each cell (our DNA provides instructions governing the function of each cell in our body, and ultimately how our body looks and functions as a whole). […] Ultimately, however, scientists do not know why these mutations occur, especially in children. […] A risk factor is anything that increases an individuals chances of developing a disease like a brain or spinal cord tumor. […] There are very few known risk factors associated with this type of childhood cancer. The only two well-established risk factors are radiation exposure and certain rare inherited genetic conditions.
- #1 Spinal Cancer: Causes, Symptoms & Treatmentshttps://www.cancercenter.com/cancer-types/spinal-cancer
Primary spinal cancer develops from cells within the spinal cord or in the surrounding structure of bones, tissues, fluid and nerves. […] The causes of spinal tumors are still largely unknown. Although some genetic conditions may contribute to the development of spinal cancer, the risk factors are much less defined for spinal cancer than for other forms of cancer. […] Known risk factors for spine cancer include: Prior history of cancer, with breast cancer, lung cancer, prostate cancer and multiple myeloma most likely to spread to the spine; Compromised immune system; Hereditary disorders, including Von Hippel-Lindau disease and neurofibromatosis (NF2); Radiation therapy exposure; Chemical exposure, including to industrial chemicals. […] Having some hereditary diseases, a compromised immune system, previous radiation therapy or exposure to some chemicals may increase the risk of developing spinal cancer.

Anyone can develop a primary brain or spinal cord tumor, but the overall risk is very small. Among people who do develop CNS tumors, theyâre most common in older adults. […] Researchers are still figuring out why CNS tumors develop, especially primary ones. Possible causes include: viral infections, exposure to certain chemicals, radiation, or hazardous materials, immune system disorders. […] Some conditions that cause tumors tend to run in families and gene mutations or genetic diseases can lead to primary CNS tumors. They can include: Neurofibromatosis, Tuberous sclerosis, von Hippel Lindau disease. […] Other risk factors for developing a primary CNS tumor include race (White men, for instance, are more likely to develop a CNS tumor) and occupation. Specifically, workers in jobs that require repeated contact with ionizing radiation or certain chemicals including materials used in building supplies, plastics, textiles have a greater chance of developing a brain tumor.

Direct or indirect exposure to cancerous chemicals or substances may lead to the cause of spinal cord tumors. These substances may transfer by air or by physical contact. These substances may be present in the environment. […] A compromised immune system may lead to spinal cord tumors as it increases the prevalence of spinal cord lymphomas. These lymphomas affect the immune cells i.e. lymphocytes. […] Secondary tumors, also known as metastasized tumors, are a common cause of spinal cord tumors. These tumors are spread to the spine from elsewhere in the body. Usually, they spread by entering the systems that are responsible for the exchange of fluids around the body such as the lymphatic system or the bloodstream. These systems transfer the cancer cells with the fluid they are already supplying. Spinal tumors may also develop from the primary tumor present nearby such as in the liver, lungs, abdomen, and bones.

[…] But what causes these gene mutations? In the vast majority of cases, scientists simply do not know why these gene mutations occur. […] However, in some rare cases, gene changes stemming from inherited genetic syndromes may carry an elevated risk of developing a spinal cord or brain tumor.

- #2 Intramedullary Spinal Cord Tumors: Practice Essentials, Epidemiology, Etiologyhttps://emedicine.medscape.com/article/251133-overview
The etiology of intramedullary spinal tumors remains obscure but undoubtedly varies according to histology. Most intramedullary spinal cord tumors are considered to be glial in origin because they are histologically and immunohistochemically similar to differentiated non-neuronal cell types, such as ependymal cells and astrocytes, which occur in nonpathologic spinal cord tissue. The traditional thinking is that tumors occur when these differentiated cells, which normally stop propagating after spinal cord development, acquire mutations that cause them to divide again in an uncontrolled fashion. […] There is increasing evidence that genes regulating radial glial cell differentiation play a role in molecular pathogenesis. Compared to supratentorial and posterior fossa ependymomas, spinal ependymomas overexpressed homeobox (HOX) family genes and insulinlike growth factor 1 (IGF1). Distinct malignant transformations in regional radial glial cells also can give rise to anatomically and molecularly distinct ependymomas. These findings underscore the notion that cranial and spinal ependymomas should be considered separately, for both clinical management and biological investigation.
- #2 Spinal Tumors – AANShttps://www.aans.org/patients/conditions-treatments/spinal-tumors/
The cause of most primary spinal tumors is unknown. Some of them may be attributed to exposure to cancer-causing agents. Spinal cord lymphomas, which are cancers that affect lymphocytes (a type of immune cell), are more common in people with compromised immune systems. There appears to be a higher incidence of spinal tumors in particular families, so there is most likely a genetic component. […] In a small number of cases, primary tumors may result from presence of these two genetic diseases: […] Neurofibromatosis 2: In this hereditary (genetic) disorder, benign tumors may develop in the arachnoid layer of the spinal cord or in the supporting glial cells. […] Von Hippel-Lindau disease: This rare, multi-system disorder is associated with benign blood vessel tumors (hemangioblastomas) in the brain, retina and spinal cord, and with other types of tumors in the kidneys or adrenal glands.
- #2 Spinal tumor Information | Mount Sinai – New Yorkhttps://www.mountsinai.org/health-library/diseases-conditions/spinal-tumor
A spinal tumor is a growth of cells (mass) in or around the spinal cord. […] Any type of tumor may occur in the spine, including primary and secondary tumors. […] The cause of primary spinal tumors is unknown. Some primary spinal tumors occur with certain inherited gene mutations. […] Secondary tumors or metastasis: these tumors are cancer cells coming from other areas of the body. […] Prostate, lung, breast, thyroid, and kidney cancer tend to spread to the bones including the spine.

The cause of spinal tumors is unknown. Most extradural tumors are metastatic commonly from breast, prostate, lung, and kidney cancer. […] The majority of extradural tumors are due to metastasis, most commonly from breast, prostate, lung, and kidney cancer. […] The cause of the majority of spinal tumors is currently not known. Primary spinal tumors are associated with a few genetic syndromes. […] Neurofibromas are associated with neurofibromatosis 1 (NF1). Meningiomas and schwannomas are associated with neurofibromatosis 2 (NF2). Intramedullary hemangioblastomas can be seen in patients with von Hippel-Lindau disease. Spinal cord lymphomas are commonly seen in patients with suppressed immune systems.
- #2 Spinal Tumors | Living With Paralysis | Reeve Foundationhttps://www.christopherreeve.org/todays-care/living-with-paralysis/health/causes-of-paralysis/spinal-tumors/
Tumors develop because of mutations (genetic changes) in the DNA tissue within cells. This allows the affected tissue to grow faster than normal. Causes of tumor development can be from gene mutations, inherited conditions, family histories of cancer, exposure to toxins including smoking and benzine among others, radiation exposure, excessive sunlight exposure, obesity, and viruses. […] Secondary Tumors are cancerous. These are called secondary tumors because affected cells have traveled from some other location in the body. However, secondary tumors can also arise at the site of origin. […] Ewings sarcoma is a bone and soft tissue cancer occurring in children and young adults. This cancer is not inherited but develops from spontaneous changes in the genes EWSR1 chromosome 22 and FLI1. It changes the genetic makeup of the individual.

Certain genetic conditions, such as neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and von HippelLindau disease, are associated with an increased risk of developing a spinal cord tumor. These conditions involve specific genetic mutations that predispose individuals to tumor growth in the nervous system, including the spinal cord. […] Previous exposure to radiation, either during medical treatment or for occupational reasons, has been linked to an increased risk of developing a spinal cord tumor. Radiation-related spinal cord tumors are relatively rare but can occur years after radiation therapy. […] Spinal cord tumors can occur in people of any age or sex. Although most cases occur sporadically without a clear underlying cause, patients with certain genetic conditions, excessive radiation exposure, and/or previous history of cancer can be at increased risk of developing a spinal cord tumor.

Causes of Spinal Cord Tumors Explained Learning about spinal cord tumor causes is complex. These neurological tumors come from many things. Things like genes, family history, and work can cause them. […] As we get older, our genes and spine can change. This makes us more likely to get spinal cord tumors. Things like what we eat, how active we are, and our gender also matter. Some people are more at risk because of their health or infections. […] Genetic factors are key in spinal cord tumors. Knowing how genes affect tumors helps in early detection and treatment. […] Genes passed down from parents can increase the risk of spinal cord tumors. Mutations in certain genes can cause cells to grow too much. This risk is higher if thereâs a family history. […] Studies show that some chemicals and toxins can cause spinal cord tumors. Workers in certain jobs face a big risk. For example, farmers often use pesticides, which can harm their health.

Some studies show a link between infections and tumors. This is seen in viral oncogenesis. Here, viruses might help make tumors, including those in the spinal cord. These tumors happen when viruses mix their genes with host cells. This can cause changes that lead to cancer. […] Some genetic disorders raise the chance of getting spinal cord tumors. For example, neurofibromatosis types 1 and 2 are genetic conditions linked to these tumors. People with these conditions should watch their health closely and get regular check-ups. […] Age is a big factor in getting spinal cord tumors. They can happen at any time but are most common in adults between 30 and 60. Gender and ethnicity might also affect the risk. Men often face a higher risk, and some groups of people might be more likely to get them. […] Your past health history is key to understanding spinal cord tumor risk. Treatments like chemotherapy and radiotherapy can raise this risk. Doctors should keep a close eye on people who have had these treatments, especially if they show signs of spinal cord problems.

Radiation exposure: exposure to large amounts of radiation is known to cause some types of cancer, including brain and spinal cord tumors in children. […] Inherited genetic conditions: in less than 5% of cases of childhood brain and spinal cord tumors, children have an inherited genetic condition that may increase their risk of developing a tumor. […] Can the development of brain and spinal cord tumors in children be prevented? […] The answer is always no. There is no known way to prevent or protect against brain or spinal cord tumors, and absolutely nothing that parents or guardians could have done to prevent this disease.

The exact cause of spinal cord tumors is often unknown, but several factors may contribute to their development. These factors include: […] Certain genetic mutations can increase the risk of developing certain types of spinal cord tumors. […] Having a family history of spinal cord tumors or other types of cancer may increase an individual’s risk of developing a spinal cord tumor. […] Exposure to certain environmental factors, such as radiation or chemicals, may increase the risk of developing a spinal cord tumor. […] The risk of developing a spinal cord tumor increases with age. […] Individuals who have received radiation therapy for another condition may be at increased risk of developing a spinal cord tumor.
- #2 Brain and Spinal Cord Cancer | Cancerhttps://health.ucdavis.edu/conditions/brain-spinal-cord-cancer
Most CNS cancers in adults are secondary tumors. Secondary tumors spread to the brain or spinal cord from cancer elsewhere in the body, such as the breast or lungs. Primary CNS cancers start in the brain or spinal cord. […] Experts arent sure what causes CNS tumors. They likely occur due to abnormal changes (mutations) in certain genes, but it’s unclear what causes these changes. Only about 5% of CNS tumors are thought to be hereditary (linked to abnormal genes passed down through families). […] Some risk factors increase your chances of developing a brain or spinal cord tumor, including: […] A small percentage of brain tumors may be hereditary, meaning theyre linked to abnormal genes or diseases passed down through families. […] Research is ongoing about links between CNS tumors and certain viruses, chemicals, cell phone use and other potential risk factors.

Researchers dont know what causes these tumors. Healthcare providers also do not have a clear idea about the risk factors for these tumors. […] A rare genetic disorder called neurofibromatosis has been linked to a higher risk of spinal cord tumors as well as other kinds of tumors. A weak immune system may also increase a person’s risk for spinal cord tumors.

Spinal tumors include benign (noncancerous) and malignant (cancerous) growths that can develop within the vertebrae (bones of the spine), next to the spinal column, or within the vertebral canal or the spinal cord. They may originate from the spine (primary tumors) or spread from another body part in people with cancer (secondary or metastatic tumors). […] There is no known direct cause of spinal tumors. Possible causes may differ depending on the type of tumor: […] Possible causes of primary tumors may include: […] Exposure to cancer-causing substances or chemicals […] Weakened immune system. Spinal cord lymphomas are more common in people who are immunocompromised […] Genetic defects. Defective genes may play a role, whether inherited or developed over time […] Secondary spinal tumors are caused by cancer cells spreading from another part of the body, often through the blood or lymphatic system. […] Types of cancer that commonly metastasize to the spine or spinal cord include: […] Breast cancer […] Lung cancer […] Colon cancer […] Lymphoma […] Melanoma […] Thyroid cancer […] Prostate cancer […] Kidney cancer.

Most tumors that grow in and around the spine are malignant less than 10% are benign. […] The risk of developing a primary spine tumor is very low. The causes are still largely unknown other than random gene mutations that are not inherited. […] The only correlation that has been made is that exposure to radiation therapy from treatment for an early childhood cancer may bring a spinal tumor into play 20 or 30 years after treatment. […] Spine tumors that spread to the spine from cancer in another part of the body, however, are far more common. About 30 70% of cancers will spread to the spine at some point. Cancers that are most likely to spread to the spine include lung, prostate and breast cancers.
