Torbiele trzustki
Etiologia i przyczyny

Torbiele trzustki to zmiany wypełnione płynem, których częstość wzrasta z wiekiem, sięgając około 25% u osób w wieku 70 lat. Podstawowy podział obejmuje torbiele nieepitelialne (głównie pseudotorbiele powstałe w wyniku zapalenia trzustki lub urazu) oraz neoplastyczne torbiele nabłonkowe, które mogą mieć charakter łagodny, przednowotworowy lub złośliwy. Pseudotorbiele pojawiają się zwykle 4-6 tygodni po ostrym zapaleniu trzustki i zawierają płyn bogaty w amylazę. Do głównych czynników etiologicznych należą: zapalenie trzustki (w tym alkoholowe, kamicze), urazy jamy brzusznej, choroby genetyczne (np. von Hippel-Lindau, ADPKD, mukowiscydoza) oraz mutacje genetyczne w genach KRAS, GNAS, BRCA, TP53, p16/CDKN2A i SMAD4. Dodatkowo, czynniki metaboliczne jak hiperkalcemia i hipertriglicerydemia (>1000 mg/dl) oraz palenie tytoniu i cukrzyca zwiększają ryzyko powstawania torbieli.

Etiologia torbieli trzustki

Torbiele trzustki są to wypełnione płynem zmiany zlokalizowane w obrębie lub na powierzchni trzustki. Częstość ich występowania zwiększa się wraz z wiekiem, dotykając około 25% osób w wieku 70 lat. Badania obrazowe, takie jak tomografia komputerowa (CT) czy rezonans magnetyczny (MRI), coraz częściej wykrywają te zmiany przypadkowo, podczas diagnostyki innych schorzeń.123

Etiologia torbieli trzustki jest różnorodna i zależy od ich klasyfikacji. Główny podział obejmuje torbiele nieoplastyczne (nienowotworowe) oraz neoplastyczne (nowotworowe lub potencjalnie nowotworowe). Chociaż dokładna przyczyna powstawania większości torbieli trzustki pozostaje nieznana, zidentyfikowano szereg czynników wpływających na ich rozwój.456

Zapalenie trzustki jako przyczyna torbieli

Jedną z głównych przyczyn powstawania torbieli trzustki, szczególnie pseudotorbieli, jest zapalenie trzustki (pancreatitis). Pseudotorbiele rozwijają się, gdy dochodzi do przerwania ciągłości głównego przewodu trzustkowego lub jego odnóg, co prowadzi do wynaczynienia enzymów trzustkowych do miąższu narządu i tworzenia zbiorników płynu.78

Zapalenie trzustki może mieć charakter ostry lub przewlekły. Najczęstszymi przyczynami zapalenia trzustki są:910

  • Nadmierne spożycie alkoholu (odpowiada za ponad 70% przypadków pseudotorbieli w krajach o wysokim spożyciu alkoholu)
  • Kamica żółciowa
  • Urazy jamy brzusznej
  • Przyczyny idiopatyczne

1112

Pseudotorbiele trzustki zazwyczaj pojawiają się 4-6 tygodni po epizodzie ostrego zapalenia trzustki. Są one wypełnione płynem bogatym w amylazę i otoczone ścianą z tkanki ziarnistej lub włóknistej, bez wyściółki nabłonkowej. Około jednej trzeciej pseudotorbieli jest zlokalizowanych w okolicy głowy trzustki, a pozostałe dwie trzecie występują w trzonie i ogonie.13

Czynniki genetyczne i schorzenia dziedziczne

Niektóre torbiele trzustki są związane z rzadkimi chorobami genetycznymi. Do najważniejszych z nich należą:1415

  • Choroba von Hippel-Lindau – rzadkie zaburzenie genetyczne, które może wpływać na trzustkę i inne narządy
  • Autosomalnie dominująca wielotorbielowatość nerek (ADPKD) – choroba, która obok nerek może także powodować tworzenie torbieli w trzustce
  • Mukowiscydoza (zwłóknienie torbielowate) – w zaawansowanych przypadkach może prowadzić do torbielowatości trzustki
  • Izolowana wielotorbielowatość trzustki (IPDP)

1617

Badania wykazały również obecność określonych mutacji genetycznych związanych z torbielami trzustki. Dwa główne geny związane z torbielami trzustki to KRAS i GNAS. Inne geny związane z wyższym ryzykiem rozwoju raka, takie jak mutacje BRCA, mogą również odgrywać rolę w powstawaniu torbieli. Późne mutacje w progresji do nowotworu złośliwego, takie jak mutacje TP53, p16/CDKN2A i SMAD4, mogą wskazywać na zmianę wysokiego ryzyka.1819

Urazy i czynniki mechaniczne

Urazy jamy brzusznej są istotnym czynnikiem ryzyka rozwoju torbieli trzustki, szczególnie pseudotorbieli. Do najczęstszych przyczyn urazowych należą:2021

  • Wypadki komunikacyjne
  • Urazy tępe brzucha
  • Urazy podczas aktywności sportowej
  • Urazy pourazowe po zabiegach chirurgicznych

22

Mechanizm powstawania torbieli pourazowych wiąże się z uszkodzeniem tkanki trzustkowej, co prowadzi do wycieku enzymów trzustkowych i formowania się zbiorników płynu. Urazy mogą również wyzwalać zapalenie trzustki, które samo w sobie jest czynnikiem ryzyka rozwoju torbieli.23

Inne czynniki ryzyka

Oprócz wymienionych przyczyn, istnieje szereg innych czynników ryzyka związanych z powstawaniem torbieli trzustki:2425

  • Podwyższony poziom wapnia we krwi (hiperkalcemia) – może uszkadzać trzustkę i przyczyniać się do powstawania torbieli
  • Bardzo wysoki poziom tłuszczów we krwi (hipertriglicerydemia) – poziom trójglicerydów powyżej 1000 mg/dl zwiększa ryzyko zapalenia trzustki
  • Uszkodzenie trzustki spowodowane lekami
  • Choroby autoimmunologiczne
  • Palenie tytoniu – może przyspieszać uszkodzenie trzustki spowodowane zapaleniem
  • Cukrzyca – związana ze zwiększonym ryzykiem rozwoju torbieli trzustki
  • Zakażenia – rzadko, torbiele trzustki mogą być spowodowane infekcjami, takimi jak gruźlica, zakażenie tasiemcem lub inne zakażenia pasożytnicze

2627

Historia rodzinna raka trzustki również może zwiększać ryzyko rozwoju torbieli trzustki, zwłaszcza tych o potencjale nowotworowym.28

Klasyfikacja torbieli trzustki i ich etiologia

Torbiele trzustki można sklasyfikować w zależności od ich pochodzenia, budowy histologicznej oraz potencjału nowotworowego. Zrozumienie różnic między poszczególnymi typami torbieli jest kluczowe dla właściwego postępowania diagnostycznego i terapeutycznego.29

Torbiele nieepitelialne

Torbiele nieepitelialne dzielą się na nienowotworowe i nowotworowe:30

  • Nienowotworowe – obejmują przede wszystkim pseudotorbiele, które powstają w wyniku zapalenia trzustki lub urazu
  • Nowotworowe – do tej grupy należą limfangiomy (łagodne) oraz mięsaki z degeneracją torbielowatą (złośliwe)

Torbiele epitelialne

Większość torbieli trzustki należy do kategorii neoplastycznych torbieli nabłonkowych. Można je podzielić na:3132

Torbiele łagodne pochodzenia nabłonkowego:

  • Torbielakogruczolak surowiczy (SCA) – prawie zawsze niezłośliwy, niewykazujący potencjału nowotworowego
  • Torbiele dermoidalne – rzadsze zmiany
  • Torbielowate hamartoma – rzadkie zmiany
  • Torbiele proste – rzadkie, zwłaszcza u dorosłych

3334

Torbiele przednowotworowe pochodzenia nabłonkowego:

  • Śluzowe zmiany torbielowate (MCN) – występują prawie wyłącznie u kobiet, najczęściej w średnim wieku, zlokalizowane zazwyczaj w trzonie lub ogonie trzustki; mają potencjał nowotworowy
  • Wewnątrzprzewodowe brodawkowate nowotwory śluzowe (IPMN) – rozwijają się w przewodach trzustkowych, mogą być prekursorem raka trzustki; ryzyko transformacji nowotworowej jest wyższe w przypadku IPMN głównego przewodu trzustkowego

3536

Złośliwe torbiele nabłonkowe:

  • Inwazyjne raki powstające z MCN lub IPMN
  • Torbielowate gruczolakoraki przewodowe
  • Torbielowate guzy neuroendokrynne
  • Lite brodawkowate nowotwory – występują głównie u kobiet poniżej 35 roku życia, zazwyczaj zlokalizowane w trzonie lub ogonie trzustki

3738

Torbiele trawienne i retencyjne

W wyniku niedrożności przewodów trzustkowych mogą powstawać torbiele retencyjne. Przyczyny obejmują:39

  • Przewlekłe zapalenie trzustki z tworzeniem się złogów wapniowych lub czopów białkowych w przewodach trzustkowych
  • Guzy trzustki powodujące ucisk na przewody
  • Zwężenia pourazowe przewodów

Torbiele pasożytnicze

Rzadką przyczyną torbieli trzustki są choroby pasożytnicze, takie jak:4041

  • Bąblowica (echinococcosis)
  • Glistnica (ascariasis)
  • Schistosomatoza

Potencjał nowotworowy torbieli trzustki

Niektóre rodzaje torbieli trzustki mają potencjał transformacji nowotworowej, co jest istotnym aspektem ich etiologii i naturalnego przebiegu.4243

Ryzyko złośliwienia zależy od typu torbieli:4445

  • Torbielakogruczolaki surowicze (SCA) – praktycznie nie wykazują potencjału nowotworowego
  • Pseudotorbiele – nie mają potencjału złośliwienia
  • IPMN głównego przewodu trzustkowego – najwyższe ryzyko transformacji nowotworowej, sięgające 60-70%
  • IPMN bocznych przewodów – niższe ryzyko złośliwienia niż IPMN głównego przewodu
  • MCN – umiarkowane ryzyko transformacji nowotworowej, zależne od wielkości zmiany i wieku pacjenta

4647

Czynniki zwiększające ryzyko złośliwienia torbieli obejmują:4849

  • Duży rozmiar torbieli (zwłaszcza powyżej 3 cm)
  • Obecność guzków w ścianie torbieli
  • Pogrubienie ściany torbieli
  • Poszerzenie głównego przewodu trzustkowego
  • Starszy wiek pacjenta
  • Obecność późnych mutacji genetycznych (K-ras, p53)
  • Podwyższony poziom CEA w płynie torbieli (powyżej 200 ng/ml)

Rola mikrobioty w rozwoju torbieli trzustki

Nowsze badania sugerują możliwy związek między mikrobiotą a rozwojem torbieli trzustki. Analizy płynu z torbieli trzustki wykazały obecność unikalnego ekosystemu bakteryjnego, co rodzi pytania o rolę bakterii w powstawaniu tych struktur.50

Obecność określonych bakterii w torbielach trzustki może potencjalnie wpływać na rozwój procesów patofizjologicznych w trzustce, choć dokładny mechanizm tego zjawiska wymaga dalszych badań. Nie stwierdzono statystycznego związku między obecnością DNA bakteryjnego w płynie torbieli a typem zmiany.51

Zmienność torbieli trzustki wraz z wiekiem

Częstość występowania torbieli trzustki zwiększa się znacząco wraz z wiekiem. Szacuje się, że dotykają one około 10-20% osób powyżej 60 roku życia i około 25% osób w wieku 70 lat. Torbiele trzustki są rzadko obserwowane u dzieci i młodzieży, z wyjątkiem torbieli prostych, które mogą mieć charakter wrodzony.525354

Naturalne zmiany trzustki związane z wiekiem, takie jak zwłóknienie i zanik tkanki gruczołowej, mogą przyczyniać się do zwiększonego ryzyka powstawania torbieli u osób starszych.55

Podsumowanie etiologii torbieli trzustki

Etiologia torbieli trzustki jest wieloczynnikowa i obejmuje szereg procesów patologicznych. Najważniejsze przyczyny i czynniki ryzyka to:565758

  • Zapalenie trzustki (ostre i przewlekłe) – główna przyczyna pseudotorbieli
  • Nadużywanie alkoholu – kluczowy czynnik prowadzący do zapalenia trzustki i rozwoju torbieli
  • Kamica żółciowa – istotny czynnik ryzyka zapalenia trzustki
  • Urazy jamy brzusznej – mogą prowadzić bezpośrednio do powstawania pseudotorbieli
  • Choroby genetyczne (choroba von Hippel-Lindau, wielotorbielowatość nerek, mukowiscydoza)
  • Mutacje genetyczne (KRAS, GNAS, BRCA i inne)
  • Wiek – zwiększona częstość występowania u osób starszych
  • Zaburzenia metaboliczne (hiperkalcemia, hipertriglicerydemia)
  • Rzadko infekcje (gruźlica, zakażenia pasożytnicze)

5960

Chociaż większość torbieli trzustki jest niezłośliwa, niektóre typy, zwłaszcza IPMN i MCN, mają potencjał transformacji nowotworowej. Zrozumienie etiologii i czynników ryzyka torbieli trzustki jest kluczowe dla właściwego postępowania diagnostycznego i terapeutycznego, szczególnie w kontekście potencjalnego ryzyka rozwoju raka trzustki.6162

Badania nad przyczynami powstawania torbieli trzustki są kontynuowane, a dokładniejsze zrozumienie mechanizmów ich rozwoju może w przyszłości przyczynić się do opracowania skuteczniejszych metod profilaktyki i leczenia tych zmian.63

  • #1 Pancreatic Cyst: Symptoms, Causes, Types & Treatment
    https://my.clevelandclinic.org/health/diseases/pancreatic-cyst
    A pancreatic cyst is a type of tumor that grows on or in your pancreas. Its typically liquid inside, with an outer skin. Less than 1% of pancreatic cysts become cancerous, but healthcare providers keep them under surveillance just in case. […] Some pancreatic cysts seem to be related to inflammation (pancreatitis), but most occur for unknown reasons. Most pancreatic cysts wont cause any problems. Rarely, a neoplastic type of cyst can be the start of pancreatic cancer. This is more likely if you have a family history of pancreatic cancer. […] Pancreatic cysts are abnormal growths, which means that a genetic mutation occurred. But researchers dont know why these occur. They might be partly hereditary and partly triggered by other factors, like inflammation and aging. A small percentage of cysts directly relate to hereditary conditions.

    Pancreatic cysts are often detected in patients undergoing imaging with either computed tomography (CT) or magnetic resonance imaging (MRI) for unrelated reasons. […] The etiology of pancreatic cysts varies widely depending on if they are non-neoplastic or neoplastic. Moreover, they are often found incidentally. As above, a history of pancreatic cancer and/or pancreatitis can increase the risk of developing pancreatic cysts. Neoplastic cysts include IPMN which includes main duct IPMN, branch duct IPMN, and mixed IPMN, mucinous cystic neoplasm, solid pseudopapillary neoplasm, and cystic pancreatic neuroendocrine tumors. Nonneoplastic cysts include serous cystic adenoma, simple cysts, lymphoepithelial cysts, and mucinous nonneoplastic cysts.

    Pancreatic cysts become more common as you get older. They affect an estimated 25% of people in their 70s. […] The exact reason for most pancreatic cysts is still idiopathic (unknown). However, some cysts might be partly hereditary and partly triggered by other factors, including: […] Genetic Disorders: As mentioned above, hereditary syndromes, including von Hippel-Lindau disease, cystic fibrosis, and polycystic kidney disease, are associated with pancreatic cysts. […] Pancreatitis: Pancreatitis, both acute and chronic, is a leading cause of pancreatic cysts. Inflammation can lead to the leakage of pancreatic enzymes, forming pseudocysts. […] Alcohol use: Over-alcohol consumption is the leading contributor to many health conditions, particularly pancreatitis, raising the risk for pancreatic cysts.

    Pancreatic cysts can be classified as either of non-epithelial or epithelial origin, and within each of those categories as non-neoplastic or neoplastic. […] Non-epithelial neoplastic cysts include lymphangiomas (benign) and sarcomas with cystic degeneration (malignant). […] The vast majority of pancreatic cysts fall into the category of neoplastic epithelial cysts. […] Benign cysts of epithelial origin include most importantly serous cystadenomas, but also include less common conditions such as dermoid cysts and cystic hamartomas. […] Pre-malignant cysts of epithelial origin include the two most challenging conditions mucinous cystic neoplasm (MCN) and intraductal papillary mucinous neoplasm (IPMN). […] Malignant epithelial cysts include invasive carcinomas that arise from either MCN or IPMN, cystic ductal adenocarcinomas, cystic neuroendocrine tumors, and solid pseudopapillary tumors. […] The risk of high-grade dysplasia, in-situ or invasive malignancy is on the order of 60-70%. […] Although they have malignant potential, the risk is low and dependent on specific cyst features.
  • #7 Pancreatic Pseudocyst – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK557594/
    Pseudocysts are formed when disruption of the main pancreatic duct or its branches, either from inflammation or direct injury, causes extravasation of pancreatic enzymes into the parenchyma and eventually forms a distinct collection. Pseudocysts arise as a complication of pancreatitis. Therefore, it follows that the causes of pseudocyst formation are the same as the causes of pancreatitis. It appears that alcohol-related pancreatitis is the major cause of pancreatic pseudocyst formation in countries where alcohol consumption is higher as it contributes to over 70% of the cases. The remaining causative factors are biliary stones, trauma, or idiopathic. […] A pseudocyst is formed following an episode of acute pancreatitis, often within 4 to 6 weeks of that episode, with a well-defined wall lined by granulation or fibrous tissue. They are filled with amylase rich fluid. About one-third of pseudocysts are located near the head of the gland, and the remaining two-thirds occur in the tail. The pathogenesis of a pseudocyst formation in chronic pancreatitis is not well understood, but it may involve acute exacerbation of underlying pancreatitis with new calculus or protein plug formation in the pancreatic ducts.

    A cyst is by definition a hollow growth, but it can be filled with fluid, including pus, solid cheesy or chunky matter, or even air. These closed, sac-like pockets of tissue can happen anywhere in the body. Cysts that develop in the pancreas are called pancreatic cysts. […] While these cysts may sound alarming, theyre often benign. More than 90 percent of pancreatic cysts are not cancerous, although some may be considered pre-cancerous. […] Having a lot of cysts may be a sign of a specific medical syndrome that could increase the risk for pancreatic and other cancers. […] Some genetic mutations that lead to the development of pancreatic cysts also increase cancer risk. These are called hereditary cancer syndromes. […] Injuries and pancreatitis are the most common causes of pancreatic cysts. Pancreatitis can develop from a disease such as alcoholism, from having a gallstone lodge in a duct, or from trauma. Rarely, pancreatic cysts can be caused by an infection such as tuberculosis, tapeworms or other organisms. […] Pancreatic cysts are also associated with certain rare inherited and/or congenital syndromes (conditions the patient is born with).

    About 10% to 20% of people over the age of 60 have pancreas cysts, says surgical oncologist Michael Kim, M.D. Most of these are benign and will never cause problems. […] But if you have pancreas cysts, you are more likely to develop pancreatic cancer. […] There are two main genes associated with cysts in the pancreas: KRAS and GNAS. Kim says other genes associated with higher cancer risk, like BRCA mutations, can also play a role in cyst development. […] Were not sure why some people have cysts that develop into cancer and some dont, Kim says. […] Some are more likely to develop into cancer than others.

    https://www.mdpi.com/2673-5261/2/1/2
    Mucinous pancreatic cysts are precursor lesions of ductal adenocarcinoma. […] Discoveries of the molecular alterations detectable in pancreatic cyst fluid (PCF) that help to define a mucinous cyst and its risk for malignancy have led to more routine molecular testing in the preoperative evaluation of these cysts. […] While testing PCF for carcinoembryonic antigen (CEA) is a very specific test for a mucinous etiology, many mucinous cysts do not have an elevated CEA. […] In these cases, detection of a KRAS and/or GNAS mutation is highly specific for a mucinous etiology, with GNAS mutations supporting an intraductal papillary mucinous neoplasm. […] Late mutations in the progression to malignancy such as those found in TP53, p16/CDKN2A, and/or SMAD4 support a high-risk lesion. […] The aim of this review is to summarize how cytopathologists approach the diagnosis of pancreatic cysts and how molecular testing impacts this diagnosis and ultimately patient care.

    Pancreatic cysts are saclike pockets of fluid on or in your pancreas. […] The main categories of pancreatic cysts can be divided into two groups, nonneoplastic or neoplastic cysts. Each group includes many different subtypes of cysts, such as pseudocysts, serous cystadenomas and mucinous cystic neoplasms. Most aren’t cancerous, and many don’t cause symptoms. But some pancreatic cysts can be or can become cancerous. […] The cause of most pancreatic cysts is unknown. Some cysts are associated with rare illnesses, including polycystic kidney disease or von Hippel-Lindau disease, a genetic disorder that can affect the pancreas and other organs. […] Pseudocysts often follow a bout of a painful condition in which digestive enzymes become prematurely active and irritate the pancreas (pancreatitis). Pseudocysts can also result from injury to the abdomen, such as from a car accident. […] Heavy alcohol use and gallstones are risk factors for pancreatitis, and pancreatitis is a risk factor for pseudocysts. Abdominal injury is also a risk factor for pseudocysts.

    Pancreatic cysts are collections (pools) of fluid that can form within the head, body, and tail of the pancreas. Some pancreatic cysts are true cysts (non-inflammatory cysts), that is, they are lined by a special layer of cells that are responsible for secreting fluid into the cysts. Other cysts are pseudocysts (inflammatory cysts) and do not contain specialized lining cells. Often these pseudocysts contain pancreatic digestive juices because they are connected to the pancreatic ducts. […] Most of the inflammatory cysts of the pancreas are pancreatic pseudocysts. Pseudocysts of the pancreas result from pancreatitis (inflammation of the pancreas). The common causes of pancreatitis include alcoholism, gallstones, trauma, and surgery. […] There are two major types of pancreatic cysts; pseudocysts (inflammatory cysts) and true cysts (non-inflammatory cysts). Inflammatory cysts are benign, whereas non-inflammatory cysts can be benign, precancerous, or cancerous.

    Pancreatic cysts are saclike pockets of fluid on or in your pancreas. […] The main categories of pancreatic cysts can be divided into two groups, nonneoplastic or neoplastic cysts. Each group includes many different subtypes of cysts, such as pseudocysts, serous cystadenomas and mucinous cystic neoplasms. Most aren’t cancerous, and many don’t cause symptoms. But some pancreatic cysts can be or can become cancerous. […] The cause of most pancreatic cysts is unknown. Some cysts are associated with rare illnesses, including polycystic kidney disease or von Hippel-Lindau disease, a genetic disorder that can affect the pancreas and other organs. […] Pseudocysts often follow a bout of a painful condition in which digestive enzymes become prematurely active and irritate the pancreas (pancreatitis). Pseudocysts can also result from injury to the abdomen, such as from a car accident. […] Heavy alcohol use and gallstones are risk factors for pancreatitis, and pancreatitis is a risk factor for pseudocysts. Abdominal injury is also a risk factor for pseudocysts.
