Glejak wielopostaciowy
Rokowania, prognozy i postęp choroby

Glejak wielopostaciowy (GBM) to najagresywniejszy pierwotny nowotwór mózgu u dorosłych, sklasyfikowany jako glejak IV stopnia przez WHO, z medianą przeżycia całkowitego (OS) około 14,6 miesiąca i 5-letnim wskaźnikiem przeżycia wynoszącym 6,8-6,9%. Rokowanie jest niekorzystne, mimo agresywnego leczenia chirurgicznego, radioterapii i chemioterapii temozolomidem (TMZ), które wydłużają medianę przeżycia o około 2,5 miesiąca w porównaniu do samej radioterapii. Czynniki prognostyczne obejmują wiek pacjenta (lepsze rokowanie poniżej 55 lat), płeć (kobiety mają lepsze wyniki), stan sprawności oraz molekularne markery, takie jak metylacja promotora MGMT i mutacje IDH. Metylacja MGMT istotnie koreluje z lepszym przeżyciem i odpowiedzią na RT/TMZ (p=0,002), a przeżycie wolne od progresji po 6 miesiącach jest silnym prognostykiem (p=0,0001). Zakres resekcji chirurgicznej oraz czas od diagnozy do interwencji chirurgicznej również wpływają na wyniki leczenia.

Rozpoznanie i ogólne rokowanie w glejaku wielopostaciowym

Glejak wielopostaciowy (Glioblastoma, GBM) jest najbardziej agresywnym pierwotnym nowotworem mózgu u dorosłych, klasyfikowanym przez Światową Organizację Zdrowia (WHO) jako glejak IV stopnia. Rokowanie w tej chorobie jest generalnie bardzo złe, z medianą przeżycia całkowitego (OS) wynoszącą mniej niż 15 miesięcy oraz 5-letnim wskaźnikiem przeżycia na poziomie zaledwie 10%, nawet przy zastosowaniu agresywnego leczenia12. Według nowszych danych, 5-letni wskaźnik przeżycia dla pacjentów z glejarem wielopostaciowym może być jeszcze niższy i wynosi jedynie 6,8-6,9%34. Bez leczenia, GBM może prowadzić do śmierci w ciągu zaledwie sześciu miesięcy5.

Mediana przeżycia u dorosłych pacjentów z GBM wynosi 14,6 miesięcy, a średni czas przeżycia szacuje się na 12-18 miesięcy6. Mimo znaczących postępów w chirurgii i chemioradioterapii w ciągu ostatnich kilkudziesięciu lat, rokowanie pozostaje niepomyślne, z około 40% przeżyciem w pierwszym roku po diagnozie i 17% w drugim roku7. Wskaźniki przeżywalności i statystyki śmiertelności dla GBM pozostają praktycznie niezmienione od dziesięcioleci8.

Czynniki wpływające na rokowanie

Czynniki kliniczne i demograficzne

Po standardowej terapii, całkowite przeżycie (OS) i przeżycie wolne od progresji (PFS) wykazują korelację z wieloma cechami specyficznymi dla pacjenta, takimi jak wiek, stan sprawności i ekspresja O6-metyloguanino-DNA-metylotransferazy (MGMT)910. Wartość prognostyczna tych cech jest jednak nadal zbyt niska, aby kierować wyborem leczenia u poszczególnych pacjentów.

Młodszy wiek jest związany z lepszym rokowaniem. Pacjenci poniżej 55 roku życia mają lepsze rokowanie w porównaniu do pacjentów powyżej 55 lat. Rokowanie jest również lepsze u kobiet w porównaniu do mężczyzn11. Ponadto stan sprawności pacjenta (performance status) jest istotnym czynnikiem prognostycznym – pacjenci z dobrym stanem sprawności mają lepsze rokowanie12.

Znaczenie czynników molekularnych

Poza obrazowaniem, profilowanie molekularne stało się kluczowym elementem w prognozowaniu GBM. Dane genomowe i transkryptomiczne okazały się niezbędne do identyfikacji kluczowych markerów przeżycia, takich jak status metylacji promotora MGMT i status mutacji IDH13. Metylacja promotora MGMT jest związana z lepszym rokowaniem i przeżyciem przy zastosowaniu radioterapii z temozolomidem (RT/TMZ) w porównaniu do pacjentów bez metylacji14.

Według analizy wieloczynnikowej, metylacja MGMT (p=0,002) i przeżycie wolne od progresji po 6 miesiącach (p=0,0001) są istotnymi czynnikami prognostycznymi15. Badania wykorzystujące zaawansowane techniki bioinformatyczne, takie jak COVPRIG (Construct and Validate a Robust Prognostic Model for IDH wild-type GBM), wykazały, że wzrost wyniku COVPRIG sugeruje znacznie zmniejszone całkowite przeżycie16.

Znaczenie leczenia w rokowaniu

Rokowanie w glejaqu wielopostaciowym jest ściśle związane z zakresem resekcji chirurgicznej. Lepsze rokowanie obserwuje się u młodszych pacjentów, kobiet, osób z mutacjami IDH, poddanych całkowitej resekcji chirurgicznej, z metylacją MGMT i leczonych chemioterapią skojarzoną z radioterapią17.

Czas diagnozy i leczenia również wpływa na rokowanie. Wczesna diagnoza i wczesna interwencja chirurgiczna przez neurochirurga są związane z lepszym rokowaniem. Rokowanie jest lepsze, gdy czas między diagnostyką a operacją jest minimalny18.

Standardowe leczenie obejmuje usunięcie guza chirurgicznie, jeśli to możliwe, a następnie radioterapię wraz z temozolomidem (TMZ). Jednak nowotwór często nawraca i staje się oporny/dostosowany do leczenia19. Przyjęcie protokołu leczenia łączącego radioterapię z temozolomidem poprawiło medianę przeżycia w glejakach wysokiego stopnia o 2,5 miesiąca w porównaniu do samej radioterapii. Mimo to, prawie wszyscy pacjenci doświadczają nawrotu, a 5-letni wskaźnik przeżycia pozostaje poniżej 10%, jak było to przez ostatnie 30 lat20.

Nowoczesne metody prognozowania przeżycia w glejaku wielopostaciowym

Znaczenie biomarkerów obrazowych

W scenariuszu GBM, obrazowanie stanowi atrakcyjną opcję w porównaniu do bardziej inwazyjnych podejść opartych na biomarkerach tkankowych21. Istnieje pilna potrzeba odkrycia biomarkerów obrazowych, które mogą pomóc w selekcji pacjentów, którzy prawdopodobnie odniosą największą korzyść z leczenia chirurgicznego i/lub chemioterapii i/lub radioterapii pod względem całkowitego przeżycia (OS) i przeżycia wolnego od progresji (PFS)22.

Literatura dotycząca biomarkerów obrazowych do prognozowania przeżycia w glejaku wielopostaciowym jest obecnie zdominowana przez radiomikę, podejście, w którym setki lub nawet tysiące cech są wyodrębniane z zaznaczonych regionów guza na obrazach MR, z których każda kwantyfikuje pewną właściwość kształtu, tekstury, fal lub histogramu23. Zastosowanie radiomiki, dziedziny skupionej na ekstrakcji szczegółowych cech obrazowania, znacznie zwiększyło możliwości prognostyczne uczenia maszynowego. Analizując dane wysokowymiarowe z obrazów MRI, radiomika umożliwia modelom wykrywanie subtelnych wzorców związanych z zachowaniem guza i wynikami pacjenta24.

Wyniki ostatnich badań wskazują, że predyktory przeżycia u pacjentów z GBM obejmują zarówno wskaźniki perfuzji, jak i dyfuzji, podkreślając znaczącą rolę cech mikrostrukturalnych lub hemodynamicznych w określaniu wyników pacjenta25. W tych badaniach, cechy kształtu oraz cechy radiomiczne pierwszego i drugiego rzędu przyczyniły się do modelu predykcyjnego z map T1W, dyfuzji i perfuzji26.

Zastosowanie uczenia maszynowego i głębokiego w prognozowaniu przeżycia

Prognozowanie przeżycia jest zwykle wykonywane na podstawie cech klinicznych przy użyciu metod statystycznych. Jednak wraz z postępem metod sztucznej inteligencji, w tym uczenia maszynowego i głębokiego uczenia, badacze starają się wykorzystać te metody do prognozowania przeżycia, które mogą łączyć cechy patologiczne, histologiczne, molekularne, obrazowe i kliniczne27.

Glejak wielopostaciowy, najbardziej agresywny nowotwór mózgu, stanowi znaczące wyzwanie w prognozowaniu przeżycia pacjentów ze względu na jego heterogeniczność i oporność na leczenie. Dokładne przewidywanie przeżycia jest niezbędne do optymalizacji strategii leczenia i poprawy wyników klinicznych28. Zastosowanie uczenia maszynowego do metadanych GBM oferuje solidne podejście do prognozowania przeżycia pacjentów. Badania podkreślają potencjał modeli uczenia maszynowego do usprawnienia podejmowania decyzji klinicznych i przyczynienia się do spersonalizowanych strategii leczenia, z naciskiem na dokładność, wiarygodność i interpretowalność29.

Najlepsze wyniki osiągnięto przy użyciu algorytmu XGBoost, który osiągnął średnią ROC-AUC równą 0,90 z odchyleniem standardowym 0,07 i dokładnością 0,78 na danych testowych30. Ustalenia te podkreślają skuteczność klasyfikatorów XGB i ET w obsłudze złożonych zadań predykcyjnych, przy czym XGB nieznacznie przewyższa inne pod względem stabilności i ogólnej wydajności31.

Ostatni przegląd systematyczny wykazał, że metody uczenia maszynowego i głębokiego uczenia są szeroko stosowane do prognozowania przeżycia pacjentów z glejakiem wielopostaciowym, wykorzystując różne rodzaje danych wejściowych, takie jak cechy kliniczne, markery molekularne, cechy obrazowe, cechy radiomiczne, dane omiczne lub ich kombinację32. Prognozowanie przeżycia z wysoką dokładnością może pomóc w spersonalizowanym podejmowaniu decyzji klinicznych u pacjentów z glejakiem wielopostaciowym33.

Modele predykcyjne i personalizacja leczenia

Modele uczenia maszynowego wykorzystujące zaawansowane cechy obrazowania, takie jak te proponowane w najnowszych badaniach, mogą potencjalnie pomóc zminimalizować błąd w stratyfikacji w przyszłych badaniach klinicznych. Wysokiej jakości informacje prognostyczne mogą również potencjalnie pomóc klinicystom w dostosowaniu intensywności interwencji, w oparciu o oczekiwany wynik i względy jakości życia34.

W glejakach wielopostaciowych nowo zdiagnozowanych typu dzikiego, cechy radiomiczne MRI uzyskane z różnych komponentów zmiany na mapach parametrycznych dyfuzji i perfuzji mogą przewidywać przeżycie w sposób nieinwazyjny. To odkrycie podkreśla potencjalną wartość kliniczną radiomiki w prognozowaniu i stratyfikacji ryzyka u pacjentów z GBM35.

Wyniki badań klinicznych wskazują na silną korelację wyników testu 3D Predict Glioma z wynikami klinicznymi, co pokazuje, że ten test funkcjonalny ma wartość prognostyczną u pacjentów leczonych RT/TMZ i wspiera dostosowanie leczenia klinicznego do przewidywanej odpowiedzi testu w różnych podgrupach glejaków wysokiego stopnia36. Mediana przeżycia między pacjentami z przewidywaną odpowiedzią na temozolomid a pacjentami z przewidywanym brakiem odpowiedzi na temozolomid wykazała statystycznie istotny wzrost przeżycia wolnego od progresji przy zastosowaniu testu do przewidywania odpowiedzi w wielu podgrupach, w tym glejaków wysokiego stopnia (5,8 miesiąca), glejaka wielopostaciowego (4,7 miesiąca) i glejaqa wielopostaciowego bez metylacji MGMT (4,7 miesiąca). Całkowite przeżycie również było korzystnie rozdzielone między podgrupami, odpowiednio o 7,6, 5,1 i 6,3 miesiąca37.

Aktualne wyzwania i przyszłe kierunki w prognozowaniu przeżycia w glejaku wielopostaciowym

Ograniczenia obecnych metod prognostycznych

Pomimo postępów, wartość prognostyczna znanych czynników, takich jak wiek, stan sprawności i ekspresja MGMT, jest nadal zbyt niska, aby kierować wyborami leczenia u indywidualnych pacjentów38. Pomimo tych niepokojących faktów i liczb, istnieje nadzieja. Nauka postępuje szybko i istnieją obiecujące strategie badawcze39.

Pomimo postępów, istnieje kilka przeszkód w stosowaniu uczenia maszynowego do prognozy GBM. Jednym z najpilniejszych problemów jest nierównowaga klas, gdzie kategorie długoterminowego przeżycia są niedostatecznie reprezentowane w zbiorach danych40.

Rola ilościowych metryk dyfuzji MRI w przewidywaniu i ocenie wyników przeżycia nie została w pełni zbadana, a wyniki są często kontrowersyjne lub niezadowalające41. Dlatego celem przeglądu systematycznego jest zebranie, podsumowanie i omówienie wszystkich badań oceniających rolę metryk dyfuzji MRI w prognozowaniu przeżycia u pacjentów z GBM oraz zwiększenie świadomości na potrzeby przyszłych badań w tej dziedzinie42.

Nowe podejścia i technologie

Ostatnie badania mają na celu dostarczenie lepszych oszacowań przeżycia na podstawie wielu rodzajów danych, takich jak dane kliniczne, molekularne i obrazowe. Kombinacja wielu rodzajów danych może dać bardziej szczegółowy opis cech leżących u podstaw, które wpływają na przeżycie i ich związki, niż pojedyncze metody43.

Badacze łączą sekwencjonowanie RNA pojedynczych komórek (scRNA-seq), transkryptomikę przestrzenną i dane obrazowe histologiczne, aby opracować program uczenia maszynowego do prognozy glejaka wielopostaciowego44. Zachowanie informacji przestrzennej podczas oceny prognozy GBM jest ważne, ponieważ interakcje komórkowe i architektura guza odgrywają kluczowe role w napędzaniu ewolucji klonalnej, progresji guza i oporności terapeutycznej45.

Proponowany model CycleGAN do transferu stylu obrazów MRI T1w i T2w dla pacjentów z GBM wykazał, że zsyntetyzowany obraz może być wykorzystany do prognozowania. Zaproponowany model prognostyczny wykorzystujący CycleGAN może zmniejszyć koszty i czas skanowania obrazów, prowadząc do rozwoju przewidywania wyników pacjentów z obrazami wielokontrastowymi46.

Obecnie pracujemy także nad modelem funkcjonalnym do przewidywania wyników pooperacyjnych u pacjentów z glejakiem wysokiego stopnia przed operacją. Wyniki wskazują, że te modele mogą dokładnie przewidzieć pooperacyjne wyniki funkcjonalne w momencie początkowej diagnozy47. Najsilniejsze predyktory identyfikowane przez model obejmowały połączenia funkcjonalne (FC) między sieciami somatomotorycznymi, wzrokowymi, słuchowymi i nagrody. Wiek był również silnym predyktorem. Jednak objętość guza była tylko umiarkowanym predyktorem48.

Implikacje dla przyszłości leczenia i prowadzenia badań klinicznych

Ustalenia najnowszych badań podkreślają transformacyjny potencjał uczenia maszynowego w prognozie GBM. Dokładne przewidywania przeżycia mają głębokie implikacje dla opieki nad pacjentem, od kierowania indywidualizowanymi strategiami leczenia po identyfikację kandydatów do terapii eksperymentalnych i optymalizację alokacji zasobów49.

Pomimo tych wyzwań, badania wskazują, że modele predykcyjne bazujące na uczeniu maszynowym i głębokim mogą istotnie poprawić prognozowanie przeżycia u pacjentów z glejakiem wielopostaciowym. Przegląd systematyczny sugeruje, że wykorzystanie uczenia głębokiego do analizy wieloparametrycznych danych obrazowych dla pacjentów z glejakiem wielopostaciowym może znacznie zwiększyć zdolność stratyfikacji pacjentów według ryzyka przeżycia50.

Jednak zanim będzie możliwa integracja terapeutyczna, zewnętrzne wieloośrodkowe badania powtarzalności muszą wykazać możliwość uogólnienia, a oczekiwane korzyści muszą być mierzone w różnych sytuacjach praktyki klinicznej51. Wyniki tego badania podkreślają potrzebę dodatkowych badań nad rozwojem modeli predykcyjnych, które obejmują większe kohorty pacjentów, bardziej solidne modalności obrazowania i uzupełniające dane multi-omiczne52.

Włączając te modele do praktyki klinicznej, możemy zwiększyć opiekę nad pacjentem, umożliwiając spersonalizowane plany leczenia, które równoważą jakość życia z przeżyciem53. Ogólnie, wskaźnik przeżycia w glejaqu wielopostaciowym stale się zmienia w miarę zmiany stosowanej strategii leczenia. Mimo tych liczb, istnieje nadzieja. Wiele nowych technik badawczych jest w fazie rozwoju, niektóre z nich okazały się skuteczne w zmianie danych na temat wyników leczenia glejaka wielopostaciowego54.

    https://my.clevelandclinic.org/health/diseases/17032-glioblastoma
    Glioblastoma, formerly known as glioblastoma multiforme, is a devastating type of cancer that can result in death in fewer than six months without treatment. […] Glioblastoma may result in early death shortly after a diagnosis without treatment. But treatments are available. They may help you ease symptoms and stay comfortable or prolong your life. […] Most people live an average of 12 to 18 months after diagnosis. The five-year survival rate for glioblastoma is only about 5%. That means about 5% of people with GBM are still alive five years after their diagnosis.

    Survival Outcome Prediction in Glioblastoma: Insights from MRI Radiomics […] Despite significant advances in surgery and chemoradiotherapy over the last few decades, the prognosis for patients with GBM remains poor. The median survival remains low at only 15 months, with approximately 40% survival in the first year post diagnosis and 17% in the second year. […] The results of the present study indicate that predictive indices of survival in patients with GBM include both perfusion and diffusion indices, highlighting the significant role of microstructural or hemodynamic characteristics in determining patient outcomes. […] In our study, shape and first and second order radiomic features contributed to the prediction model from T1W, diffusion, and perfusion maps. […] In newly diagnosed wild-type GBM, MRI radiomic features derived from various components of the lesion on diffusion and perfusion parametric maps can predict survival in a non-invasive manner. This finding emphasizes the potential clinical value of radiomics in prognostication and risk stratification of GBM patients.

  • #11 What is the Prognosis of Glioblastoma? – Glioblastoma Foundation
    https://glioblastomafoundation.org/news/what-is-the-prognosis-of-glioblastoma
    Glioblastoma, or Glioblastoma Multiforme (GBM), is an aggressive stage 4 brain cancer. The prognosis for glioblastoma is generally very poor and current treatments often fall short. The median survival for a glioblastoma prognosis is just one year after diagnosis. Only 5% of glioblastoma cancer patients survive 5 years after diagnosis. […] Glioblastoma prognosis is closely related to extent of surgical resection. Improved prognosis is also seen in younger patients, females, those with IDH mutations, those undergoing gross total surgical resection, those with MGMT methylation, and those treated with combination chemotherapy plus radiation. […] Younger age has been associated with a better prognosis for glioblastoma. Patients under age 55 have an improved prognosis compared to patients over the age of 55. Prognosis is also improved for women in comparison to men.

    The use of radiomics, a field focused on extracting detailed imaging features, has significantly enhanced the prognostic capabilities of ML. By analyzing high-dimensional data from MRI scans, radiomics enables models to detect subtle patterns related to tumor behavior and patient outcomes. […] Beyond imaging, molecular profiling has emerged as a critical component in GBM prognosis. Genomic and transcriptomic data have proven essential for identifying key survival markers, such as MGMT promoter methylation and IDH mutation status. […] Multimodal frameworks that combine radiomic, molecular, and clinical data have demonstrated exceptional potential for survival prediction. […] Despite the advancements, several obstacles remain in applying ML to GBM prognosis. One of the most pressing issues is class imbalance, where long-term survival categories are underrepresented in datasets.

    High grade gliomas (HGG), including astrocytoma, IDH-mutant and glioblastoma, IDH-wildtype, are a class of aggressive brain cancers with extremely poor prognosis, and minimally effective treatment options. […] The adoption of this protocol improved median survival in HGG by 2.5 months over radiation treatment alone. Still, almost all patients undergo recurrence, and the 5 year survival rate remains less than 10%, as it has for the past 30 years. […] Methylation of the MGMT promoter is associated with better prognosis and survival with RT/TMZ compared to unmethylated patients. […] In general, all patients would benefit from a more direct knowledge of their predicted response to standard of care (SOC) prior to treatment to make informed decisions, potentially open the path to clinical trial enrollment, and maximize their time to recurrence.
  • #15 The Effect of Re-operation on Survival in Patients with Recurrent Glioblastoma | Anticancer Research
    https://ar.iiarjournals.org/content/35/3/1743
    Glioblastoma (GBM) is the most frequent malignant tumor of the central nervous system (CNS) with an incidence of 4.8/100,000 cases per year. Surgical treatment followed by temozolomide (TMZ) concomitant with and adjuvant to radiotherapy (RT) is the cornerstone of treatment for newly-diagnosed GBM that allows for improvement in progression-free survival (PFS) and overall survival (OS). Nevertheless, despite optimal treatments, patients experience disease progression and median survival does not exceed 12-14 months with a 5-year survival rate of 10%. […] Re-surgery is often used both for confirmation of recurrent disease and for debulking to provide symptoms relief; however, there is no evidence that re-surgery might increase survival. […] In multivariate analysis, no significant effect of re-surgery was found, with age (p=0.001), MGMT methylation (p=0.002) and PFS at 6 months (p=0.0001) being significant prognostic factors.

    Accurately predicting the outcome of isocitrate dehydrogenase (IDH) wild-type glioblastoma (GBM) remains hitherto challenging. This study aims to Construct and Validate a Robust Prognostic Model for IDH wild-type GBM (COVPRIG) for the prediction of overall survival using a novel metric, genegene (GG) interaction, and explore molecular and cellular underpinnings. COVPRIG was designed for RNA-seq and microarray, respectively, and effectively identified patients at high risk of mortality. The predictive performance of COVPRIG was satisfactory, with area under the curve (AUC) ranging from 0.56 (CGGA693, RNA-seq, 6-month survival) to 0.79 (TCGA RNAseq, 18-month survival), which can be further validated by decision curves. The prognostic significance of COVPRIG was also validated in GBM including the IDH mutant samples. Notably, COVPRIG was comprehensively evaluated and externally validated, and a systemic review disclosed that COVPRIG outperformed current validated models with an integrated discrimination improvement (IDI) of 616%. Moreover, integrative bioinformatics analysis predicted an essential role of METTL1+ neural-progenitor-like (NPC-like) malignant cell in driving unfavorable outcome. This study provided a powerful tool for the outcome prediction for IDH wild-type GBM, and preliminary molecular underpinnings for future research. The outcome of IDH wild-type GBM can be heterogeneous. IDH wild-type GBM is classified as proneural, classical, and mesenchymal subtypes based on the transcriptome, with the latter having the worst prognosis. Compelling evidence illuminates that stem-like tumor cell, which is at the interface of neural and glioma biology, is essential in tumor progression and treatment resistance. In this study, we developed a robust prognostic model for IDH wild-type GBM through incorporating a novel parameter, GG interaction, to effectively identify patients at high mortality risk. In addition, comprehensive bioinformatics analysis pinpointed a subset of NPC-like cells as an essential player in driving unfavorable outcome. The prognostic significance of COVPRIG was demonstrated, with samples split into high- and low-risk groups by the median value. KM analysis found that an increased COVPRIG score was suggestive of a significantly decreased overall survival. The hazard ratio (HR) showed a dose-response association with groups. For example, the HRgroup3vs.1 was 3.14 in the TCGA RNA-seq cohort, higher than HRgroup2vs.1 (1.63). In sum, nomograms were constructed based on RNA-seq and microarray datasets for individualized prognostic prediction. Collectively, this study provided a reference for accurately determining the prognosis of IDH wild-type GBM.

    https://glioblastomafoundation.org/news/what-is-the-prognosis-of-glioblastoma
    Glioblastoma, or Glioblastoma Multiforme (GBM), is an aggressive stage 4 brain cancer. The prognosis for glioblastoma is generally very poor and current treatments often fall short. The median survival for a glioblastoma prognosis is just one year after diagnosis. Only 5% of glioblastoma cancer patients survive 5 years after diagnosis. […] Glioblastoma prognosis is closely related to extent of surgical resection. Improved prognosis is also seen in younger patients, females, those with IDH mutations, those undergoing gross total surgical resection, those with MGMT methylation, and those treated with combination chemotherapy plus radiation. […] Younger age has been associated with a better prognosis for glioblastoma. Patients under age 55 have an improved prognosis compared to patients over the age of 55. Prognosis is also improved for women in comparison to men.

    Timing of diagnosis and treatment also influence glioblastoma prognosis. Early diagnosis and early surgical intervention by a neurosurgeon have been associated with a better prognosis. Glioblastoma prognosis is improved when the time between surgery and diagnosis is minimal. […] The overall prognosis for glioblastoma has changed little since the 1980s, and new treatments are desperately needed to improve outcomes for patients. […] While glioblastoma prognosis remains poor, we are making progress against the disease.

    Survival prediction is usually done from clinical features using statistical methods. However, with the advancement of artificial intelligence methods that include machine learning and deep learning, researchers have been eager to use these methods for survival prediction, which can combine pathology, histology, molecular, imaging, and clinical features. […] The current treatment involves removing the tumor surgically if possible, then giving radiotherapy along with temozolomide (TMZ) regimen; however, the tumor often comes back and becomes resistant/adapted to the treatment. The bad prognosis is related to many factors such as tumor diversity, weak immune response, invasion of the tumor into „normal” tissue, production of cancer stem cells, and the fast adaptation of the tumor to harsh treatment.

    High grade gliomas (HGG), including astrocytoma, IDH-mutant and glioblastoma, IDH-wildtype, are a class of aggressive brain cancers with extremely poor prognosis, and minimally effective treatment options. […] The adoption of this protocol improved median survival in HGG by 2.5 months over radiation treatment alone. Still, almost all patients undergo recurrence, and the 5 year survival rate remains less than 10%, as it has for the past 30 years. […] Methylation of the MGMT promoter is associated with better prognosis and survival with RT/TMZ compared to unmethylated patients. […] In general, all patients would benefit from a more direct knowledge of their predicted response to standard of care (SOC) prior to treatment to make informed decisions, potentially open the path to clinical trial enrollment, and maximize their time to recurrence.

    This systematic review suggests that utilizing DL to analyze multiparametric imaging data for glioblastoma patients can greatly increase the ability to stratify patients according to survival risk. […] Before therapeutic integration can happen, however, external multicenter repeatability studies must show generalizability, and expected benefits must be measured across various clinical practice situations. […] The findings of this study highlight the need for additional research into the development of predictive models that incorporate larger patient cohorts, more robust imaging modalities, and supplementary multi-omics data. […] Calibration stability across variable acquisition methodologies must be addressed to use models for risk categorization effectively through methods like dataset harmonization.

    These findings indicate the feasibility of achieving classification accuracy exceeding 90% before surgical intervention, using basic demographics, tumor volume, and RS-fMRI measures. […] Our results indicate tumor volume was only a moderate predictor of KPS, which might initially appear counterintuitive. However, this finding underscores the critical point that tumor location in relation to functional networks could have a more significant influence on functional outcomes than the size of the tumor alone. […] Our findings show a distinct dichotomy between the anatomical location of the tumor and functional connectivity (FC) changes, specifically concerning their predictive ability for KPS. […] This apparent dissociation may be due to several potential mechanisms. […] Taken together, multiple parallel processes could potentially be responsible for FC disruption and associated functional impairment: damage to gray matter regions with specific functional network affiliations, the disruption of direct/indirect connections mediated by white matter damage, and overall health. […] By incorporating these models into clinical practice, we stand to enhance patient care, enabling personalized treatment plans that balance quality of life with survival.

    GBM’s median survival rate for adults is 14.6 months, which can be devastating for patients and their loved ones. […] According to the National Brain Tumor Society, the five-year glioblastoma survival rate for patients is only 6.8 percent. […] The average length of survival for glioblastoma patients is estimated to be only 12 to 18 months. […] The glioblastoma survival rate constantly changes as the treatment strategy used changes. […] Despite these numbers, there is hope. Many new research techniques are in development, some of which have proved successful in changing data on glioblastoma treatment outcomes.
