Malformacje jamiste – Rokowania, prognozy i postęp choroby

Malformacje jamiste
Rokowania, prognozy i postęp choroby

Rokowanie w przypadku malformacji jamistych, zwłaszcza pnia mózgu, jest zróżnicowane i zależy od lokalizacji, historii krwawień, cech radiologicznych oraz leczenia. U 89,8% pacjentów z nieleczonymi malformacjami jamistymi pnia mózgu stan neurologiczny pozostaje stabilny lub ulega poprawie, a śmiertelność wynosi 1,7%. Kluczowe czynniki ryzyka pogorszenia stanu neurologicznego to wcześniejsze krwawienia (ryzyko pogorszenia wzrasta z 1,5% u pacjentów bez krwawień do 38,5% przy wielokrotnych krwawieniach), wielkość zmiany (RR 2,343 na 1 mm, p<0,001), przekraczanie punktu osiowego (RR 2,993, p<0,001), obecność żylnej anomalii rozwojowej (DVA) (RR 1,801, p=0,020) oraz głębokość zmiany (RR 1,595, p=0,021). Malformacje rdzenia kręgowego cechują się bardziej agresywnym przebiegiem i wyższym ryzykiem krwawienia. Pięcioletnie ryzyko złożonego punktu końcowego (krwawienie lub deficyt neurologiczny) wynosi 44,5% dla pnia mózgu i 8,8% dla innych lokalizacji, a roczne ryzyko krwawienia w mózgu to około 2,4%.

Prognoza Malformacji Jamistych (Cavernous Malformations) – Przewidywanie Wyników Leczenia

Rokowanie w przypadku malformacji jamistych (cavernous malformations) jest zróżnicowane i zależy od wielu czynników, w tym lokalizacji zmiany, historii krwawień, cech radiologicznych oraz zastosowanego leczenia. Dokładne poznanie naturalnego przebiegu choroby ma kluczowe znaczenie dla podejmowania decyzji terapeutycznych i skutecznego poradnictwa medycznego.¹²

Naturalny przebieg malformacji jamistych pnia mózgu

Malformacje jamiste pnia mózgu stanowią szczególne wyzwanie diagnostyczne i terapeutyczne. Badania obserwacyjne wskazują, że u większości pacjentów z nieleczonymi malformacjami jamistymi pnia mózgu (89,8%) stan neurologiczny pozostaje stabilny lub ulega poprawie w okresie obserwacji, przy wskaźniku śmiertelności wynoszącym zaledwie 1,7%.³⁴

Zbiorcza analiza dziewięciu badań wykazała, że odsetek pacjentów z poprawą lub bez zmian w stanie neurologicznym wynosił 85,2% (465 z 546), a pogorszenie stanu neurologicznego odnotowano u 14,3% (78 z 546) pacjentów, co wskazuje na bardziej łagodny przebieg choroby niż wcześniej przypuszczano.⁵

Czynniki ryzyka pogorszenia stanu neurologicznego

Zidentyfikowano kilka kluczowych czynników ryzyka związanych z pogorszeniem stanu neurologicznego u pacjentów z malformacjami jamistymi:

Krwawienia w wywiadzie – pacjenci, którzy doświadczyli wcześniejszego krwawienia, mają zwiększone ryzyko ponownego krwawienia i pogorszenia stanu neurologicznego⁶⁷
Liczba przebytych krwawień – odsetek pacjentów z pogorszeniem stanu neurologicznego wzrasta znacząco wraz z liczbą przebytych krwawień: od 1,5% (8 z 531) u pacjentów bez przebytych krwawień do 37,5% (48 z 128) przy jednym incydencie krwotocznym i 38,5% (15 z 39) przy więcej niż jednym⁸⁹
Cechy radiologiczne – analiza jednowymiarowa wykazała, że istotnymi czynnikami ryzyka pogorszenia stanu są: wielkość zmiany (na 1 mm) (RR 2,343, p<0,001), przekraczanie punktu osiowego (RR 2,993, p<0,001), obecność żylnej anomalii rozwojowej (DVA) (RR 1,801, p=0,020) oraz głębokość zmiany (RR 1,595, p=0,021)¹⁰¹¹
Lokalizacja zmiany – malformacje jamiste rdzenia kręgowego mają bardziej agresywny przebieg i wyższe ryzyko krwawienia¹²

W analizie wieloczynnikowej, po uwzględnieniu czasu obserwacji, przekraczanie punktu osiowego (RR 2,325, 95% CI 1,332-4,060, p=0,003) oraz obecność DVA (RR 1,776, 95% CI 1,037-3,041, p=0,036) były znacząco związane z pogorszeniem stanu neurologicznego.¹³¹⁴

Długoterminowe ryzyko krwawienia

Pięcioletnie ryzyko wystąpienia złożonego punktu końcowego (krwawienia lub ogniskowego deficytu neurologicznego) wynosi 44,5% dla malformacji jamistych pnia mózgu i 8,8% dla malformacji jamistych w innych lokalizacjach.¹⁵ Szacuje się, że roczne ryzyko krwawienia w przypadku malformacji jamistych mózgu wynosi około 2,4%.¹⁶

W 10-letnim badaniu obserwacyjnym skumulowane ryzyko krwawienia wynosiło:

30% dla całej kohorty pacjentów
39% dla pacjentów z krwawieniem przy rozpoznaniu
67% dla malformacji jamistych rdzenia kręgowego (ISCM)¹⁷

Badania wykazały, że ryzyko krwawienia zwiększa się z upływem czasu, szczególnie u pacjentów z krwawieniem przy rozpoznaniu i lokalizacją w rdzeniu kręgowym.¹⁸ Roczne wskaźniki krwawienia w różnych badaniach naturalnego przebiegu choroby wahają się od 0,7% do 6% na pacjenta rocznie.¹⁹

Wyniki leczenia chirurgicznego

Malformacje jamiste pnia mózgu

Badania oceniające długoterminowe wyniki resekcji malformacji jamistych pnia mózgu wskazują na korzystny przebieg pooperacyjny u większości pacjentów. W jednym z badań u 91% pacjentów (42 z 46) wynik w skali mRS (modified Rankin Scale) podczas ostatniej wizyty kontrolnej wynosił ≤ 2 (korzystny wynik), a u 39% (18 pacjentów) wynosił 0 (brak objawów neurologicznych).²⁰ System klasyfikacji Lawtona skutecznie przewiduje długoterminowy wynik po operacji.²¹

Malformacje jamiste rdzenia kręgowego

W przypadku malformacji jamistych rdzenia kręgowego, resekcja mikrochirurgiczna wspomagana śródoperacyjnym monitorowaniem neurofizjologicznym (IONM) pokazuje obiecujące wyniki. W porównaniu do stanu przedoperacyjnego, skala McCormicka w rok po zabiegu pozostała niezmieniona u 12 pacjentów i poprawiła się u 5 pacjentów, przy czym u żadnego nie wystąpiło pogorszenie. Jednakże szczegółowe badanie neurologiczne wykazało nowy lub pogorszony deficyt czuciowo-ruchowy u 4 pacjentów.²²

Odwracalne zmiany w IONM były związane z lepszym wynikiem neurologicznym w porównaniu do nieodwracalnego pogorszenia IONM podczas operacji. Ryzyko względne wystąpienia nowego deficytu neurologicznego po roku obserwacji, gdy zarejestrowano odwracalne pogorszenie IONM w porównaniu z nieodwracalnym pogorszeniem IONM, wynosiło 0,56 (0,23-1,37) dla pogorszenia MEP i 0,4 (0,18-0,89) dla pogorszenia SSEP.²³²⁴

Rodzaj zmiany IONM	Ryzyko trwałego pogorszenia neurologicznego po roku dla MEP	Ryzyko trwałego pogorszenia neurologicznego po roku dla SSEP
Odwracalna zmiana IONM	17%	25%
Nieodwracalna zmiana IONM	30%	62,5%

Jakość życia po leczeniu chirurgicznym

Długoterminowa jakość życia po resekcji malformacji jamistych jest ważnym wskaźnikiem skuteczności leczenia. Badania porównujące jakość życia pacjentów po resekcji malformacji jamistych w obszarach elokwentnych (EG) i nieelokwentnych (NEG) mózgu wykazały interesujące wyniki:²⁵²⁶

Chorobowość chirurgiczna była przejściowa w grupie NEG i w większości przypadków ustąpiła w grupie EG (85,4% pacjentów)²⁷
Pacjenci po resekcji malformacji jamistych w obszarach elokwentnych zgłaszali jakość życia niepoślednią w porównaniu do grupy NEG w większości domen kwestionariusza SF12 (z wyjątkiem roli fizycznej RP)²⁸²⁹
Jednakże, zgłaszali oni postrzeganie ogólnego stanu zdrowia jako gorsze od norm, na co wpływ miały ograniczone role fizyczne i emocjonalne³⁰³¹

Te wyniki mogą pomóc w podejmowaniu decyzji i poradnictwie pacjentów w przyszłych przypadkach malformacji jamistych w regionach elokwentnych i nieelokwentnych.³²³³

Czynniki wpływające na rokowanie

Rokowanie u pacjentów z malformacjami jamistymi zależy od wielu czynników, które należy uwzględnić podczas planowania postępowania:³⁴³⁵

Lokalizacja zmiany – malformacje jamiste podnamiotowe, szczególnie w pniu mózgu i móżdżku, wiążą się z wyższym ryzykiem niepełnosprawności neurologicznej w porównaniu do zmian nadnamiotowych³⁶
Wielkość i tempo wzrostu – większe zmiany i szybszy wzrost wiążą się z gorszym rokowaniem³⁷
Historia krwawień – wcześniejsze krwawienia zwiększają ryzyko kolejnych epizodów, choć okres zwiększonego ryzyka wydaje się być ograniczony czasowo³⁸³⁹
Płeć – wiele badań wykazało zwiększoną częstość objawowych zmian u kobiet⁴⁰
Historia napadów padaczkowych – wskaźniki nowych napadów po rozpoznaniu malformacji jamistej wynoszą od 1,5% do 4,3% na pacjenta rocznie, a historia wcześniejszych napadów zwiększa ten wskaźnik do 5,5% na pacjenta rocznie⁴¹
Dziedziczność – dostępne dowody sugerują, że większe ogólne obciążenie malformacjami jamistymi występujące w rodzinnych formach w porównaniu do sporadycznych prowadzi do wyższego rocznego ryzyka objawowego krwawienia u pacjentów z dziedziczeniem rodzinnym⁴²

Perspektywy długoterminowe

W większości przypadków malformacje jamiste pozostają stabilne, powodując niewielkie lub żadne zakłócenia w codziennym życiu pacjenta. Jednakże niektórzy pacjenci mogą nadal doświadczać objawów, takich jak napady padaczkowe lub bóle głowy, które mogą wymagać interwencji medycznej lub nawet chirurgicznego usunięcia malformacji.⁴³

Malformacje jamiste mózgu mogą zagrażać życiu, jeśli powodują ciężkie krwawienie, ale większość z nich nie wpływa na przewidywaną długość życia. Powikłania po krwawieniu mogą jednak wpływać na jakość życia, podobnie jak po udarze.⁴⁴ Należy zauważyć, że nie zebrano wystarczających danych na temat długości życia pacjentów z tą malformacją, aby przedstawić reprezentatywną analizę statystyczną.⁴⁵

Rokowanie dla osób z malformacjami jamistymi jest przede wszystkim korzystne, szczególnie gdy są one ściśle monitorowane i leczone przez wykwalifikowanych pracowników służby zdrowia. Istotne jest utrzymywanie otwartej komunikacji z zespołem medycznym i przestrzeganie zalecanych planów leczenia w celu zapewnienia najlepszego możliwego wyniku.⁴⁶

#1 Living With Cavernous Malformation | Aaron Cohen-Gadol, MD
https://www.aaroncohen-gadol.com/en/patients/cavernous-malformation/survival/living-with-cavernous-malformation
Cavernous malformation prognosis varies depending on the size, location and growth rate of the cavernoma. In many cases, cavernomas remain stable, causing little to no disruption to the individual’s daily life. However, some people may continue to experience symptoms like seizures or headaches that may require medical intervention or even surgical removal of the malformation. […] Factors such as age, medical history and cavernoma progression may all influence the prognosis. Treatments and management options are tailored to each individual’s unique circumstances and include medication, surgery and lifestyle changes to minimize the risk of severe symptoms. Regular inspections through imaging studies like MRI are often recommended to monitor any changes in the size or location of cavernomas.

Cavernous malformations (CMs) are angiographically occult, low-pressure neurovascular lesions with distinct imaging and clinical characteristics. […] Optimal management requires a thorough understanding of the natural history of CMs including consideration of issues such as mode of presentation, lesion location, and genetics that may impact the associated neurological risk. […] The purpose of this paper is to consolidate the current body of knowledge of the natural history of CMs into a form that helps the cerebrovascular practitioner with patient treatment. […] Numerous other natural history studies have been reported over the years, most of which have documented hemorrhage rates ranging from 0.7% to 6% per patient-year. […] Aiba et al. were the first to provide evidence that hemorrhagic presentation negatively impacts the natural history of CMs.

Haemorrhages of brainstem cavernous malformations (CMs) can lead to neurological deficits, the natural history of which is uncertain. The study aimed to evaluate the neurological outcomes of untreated brainstem CMs and to identify the adverse factors associated with worsened outcomes. […] The neurological outcomes of untreated brainstem CMs were improved/unchanged in majority of patients (89.8%) with a fatality rate of 1.7% in our cohort, which seemed to be favourable. Radiological features significantly predicted worsened outcomes. Our results provide evidence for clinical consultation and individualised treatment. […] The percentage of worsened outcomes significantly increased as the number of prospective haemorrhages increased (from 1.5% (8 of 531, if 0 prospective ictus) to 37.5% (48 of 128, if 1 ictus) and 38.5% (15 of 39, if 1 ictus)).

https://www.nature.com/articles/s41598-023-42594-0
Knowledge of the bleeding risk and the long-term outcome of conservatively treated patients with cavernous malformations (CM) is poor. […] Adjusted multivariate logistic regression analysis identified bleeding at diagnosis (p=0.039) and CM localization to the spine (p=0.010) as predictors for (re)hemorrhage. […] The cumulative 10-year risk of bleeding was 30% for the whole cohort, 39% for patients with bleeding at diagnosis and 67% for ISCM. […] During an untreated 10-year follow-up, the probability of hemorrhage increased over time, especially in cases with bleeding at presentation and spinal cord localization. […] Our results suggest a more aggressive course in patients with ISCM, although the small number of cases significantly limits the robustness of the analyses.

Cerebral cavernous malformation bleeds and ruptures aren’t common, but they do happen. Research estimates that you have a 2.4% chance of having a bleed annually if you have one. […] Treatment options are available. While there are risks to surgery, the outcome of removing a cerebral cavernous malformation is usually successful if your surgeon can safely access it. […] Yes, if you had a bleed, you’re at a higher risk of a future bleed. A healthcare provider will let you know how to take care of yourself to help prevent future bleeds. […] Cerebral cavernous malformations can be life-threatening if they cause severe bleeding. But most don’t affect life expectancy. Complications after a bleed, however, may affect your quality of life, like after a stroke. […] Each person’s situation is different. You should speak with your healthcare provider to learn more about your situation.
#17 Natural course of cerebral and spinal cavernous malformations: a complete ten-year follow-up study | Scientific Reports
https://www.nature.com/articles/s41598-023-42594-0
Knowledge of the bleeding risk and the long-term outcome of conservatively treated patients with cavernous malformations (CM) is poor. […] Adjusted multivariate logistic regression analysis identified bleeding at diagnosis (p=0.039) and CM localization to the spine (p=0.010) as predictors for (re)hemorrhage. […] The cumulative 10-year risk of bleeding was 30% for the whole cohort, 39% for patients with bleeding at diagnosis and 67% for ISCM. […] During an untreated 10-year follow-up, the probability of hemorrhage increased over time, especially in cases with bleeding at presentation and spinal cord localization. […] Our results suggest a more aggressive course in patients with ISCM, although the small number of cases significantly limits the robustness of the analyses.

Cavernous malformations (CMs) are angiographically occult, low-pressure neurovascular lesions with distinct imaging and clinical characteristics. […] Optimal management requires a thorough understanding of the natural history of CMs including consideration of issues such as mode of presentation, lesion location, and genetics that may impact the associated neurological risk. […] The purpose of this paper is to consolidate the current body of knowledge of the natural history of CMs into a form that helps the cerebrovascular practitioner with patient treatment. […] Numerous other natural history studies have been reported over the years, most of which have documented hemorrhage rates ranging from 0.7% to 6% per patient-year. […] Aiba et al. were the first to provide evidence that hemorrhagic presentation negatively impacts the natural history of CMs.

Microsurgical resection of spinal cord cavernous malformations can be assisted by intraoperative neurophysiological monitoring (IONM). […] The association of intraoperative IONM changes and detailed neurological outcome, however, has not been analyzed so far. […] Compared to the preoperative state, McCormick score at 1-year follow-up remained unchanged in 12 and improved in five patients, none worsened, while detailed neurological examination revealed a new or worsened sensorimotor deficit in 4 patients. […] Reversible IONM changes were associated with a better neurological outcome at follow-up compared to irreversible IONM deterioration during SCCM surgery. […] Our study favors the permanent 80% amplitude reduction criterion for MEP and 50% amplitude reduction criterion for SSEP for further prospective evaluation of IONM significance and the effectiveness of corrective maneuvers during SCCM surgeries.

The relative risk for a new neurological deficit at 1-year follow-up, when reversible IONM-deterioration was registered compared to irreversible IONM deterioration, was 0.56 (0.231.37) for MEP deterioration and 0.4 (0.180.89) for SSEP deterioration. […] A reversible IONM change was associated with a reduced risk of a permanent neurological deterioration at 1-year follow-up compared to an irreversible IONM change (for MEP and SSEP 17 vs 30% and 25 vs 62.5%, respectively). […] The relationship between reversible IONM changes and a more favorable prognosis with regard to neurological outcome alludes to the importance of IONM.

https://pmc.ncbi.nlm.nih.gov/articles/PMC8827309/
The aim of this study is to analyze the long-term quality of life after surgery of cavernoma. […] The QoL comparison between eloquent and non-eloquent cavernomas created interesting and new data after prolonged follow-up. […] At a late follow-up, the surgical morbidity was transient in the NEG and mostly recovered in the EG. […] Regarding QoL, patients after eloquent cavernoma resection reported a non-inferior QoL in most SF12 domains (except for physical role RP) compared to NEG. […] However, they reported general health perception inferior to norms, which was affected by the limited physical and emotional roles. […] These results of how these patients are doing years after surgery could improve the decision-making as well as the patient counseling for future encountered cases of cavernomas in eloquent and non-eloquent regions. […] For future studies, preoperative QoL measurements for the assessment of QoL dynamics are highly recommended.

Cavernous malformation prognosis varies depending on the size, location and growth rate of the cavernoma. In many cases, cavernomas remain stable, causing little to no disruption to the individual’s daily life. However, some people may continue to experience symptoms like seizures or headaches that may require medical intervention or even surgical removal of the malformation. […] Factors such as age, medical history and cavernoma progression may all influence the prognosis. Treatments and management options are tailored to each individual’s unique circumstances and include medication, surgery and lifestyle changes to minimize the risk of severe symptoms. Regular inspections through imaging studies like MRI are often recommended to monitor any changes in the size or location of cavernomas.

It should be noted, however, that although patients with CMs who present with symptomatic hemorrhage are at an increased risk for new hemorrhage after diagnosis, this period of higher risk appears time limited. […] In the aforementioned study by Robinson et al., a higher incidence of neurological disability was noted in patients with infratentorial than in those with supratentorial CMs. […] Many studies since have found an increase in the frequency of symptomatic lesions in women. […] The reported rates of new seizure following CM diagnosis range from 1.5% to 4.3% per patient-year, and history of a previous seizure increases this rate to 5.5% per patient-year. […] Finally, available evidence suggests that the greater overall CM burden found in familial versus sporadic forms of CMs leads to a higher annual risk of symptomatic hemorrhage for patients with familial inheritance.
