Chemo brain
Rokowania, prognozy i postęp choroby
Chemo brain, czyli zaburzenia poznawcze związane z chemioterapią, stanowią istotne wyzwanie kliniczne u pacjentów onkologicznych, z objawami utrzymującymi się od kilku miesięcy do nawet 5-10 lat po zakończeniu terapii. Szacuje się, że około 75% pacjentów doświadcza tych zaburzeń podczas leczenia, a 35% zgłasza utrzymujące się deficyty poznawcze po terapii. Główne deficyty dotyczą pamięci werbalnej i wzrokowej, szybkości przetwarzania informacji oraz pamięci roboczej. Rokowanie jest zróżnicowane i zależy od dawki chemioterapii, predyspozycji genetycznych (np. genotyp APOE4), płci oraz stanu emocjonalnego pacjenta. Neurogeneza hipokampa, kluczowa dla regeneracji mózgu, może być trwale zaburzona przez chemioterapię, co przyczynia się do długotrwałych zmian strukturalnych w istocie białej i szarej, utrzymujących się nawet do 20 lat po leczeniu.
Prognoza chemo brain (przewidywanie wyniku)
Chemo brain, nazywany również zaburzeniami poznawczymi związanymi z chemioterapią (ang. chemotherapy-related cognitive dysfunction), stanowi istotny problem dotykający pacjentów onkologicznych. Rokowanie w przypadku tego zaburzenia jest zróżnicowane i zależy od wielu czynników indywidualnych.12
Czas trwania objawów
Objawy chemo brain mogą utrzymywać się przez różny okres – od krótkotrwałych zaburzeń do długoterminowych deficytów poznawczych. Badania wykazują, że około jedna trzecia pacjentów zgłasza efekty uboczne utrzymujące się przez miesiące, a nawet od 5 do 10 lat po zakończeniu leczenia.1 Doświadczenia pacjentów są indywidualne – u niektórych objawy ustępują po zakończeniu leczenia, podczas gdy u innych mogą nigdy całkowicie nie ustąpić.1
W większości przypadków chemo brain zaczyna się poprawiać w ciągu jednego roku po zakończeniu leczenia, a poprawa zazwyczaj kontynuowana jest przez kolejne 1-2 lata. Jednak u części pacjentów niektóre uszkodzenia mózgu mogą mieć charakter trwały.1 Większość badań nad chemo brain koncentruje się na pacjentach od momentu diagnozy do 18 miesięcy po zakończeniu leczenia, jednak istnieją dowody sugerujące, że zaburzenia poznawcze mogą utrzymywać się przez wiele lat.1
Czynniki wpływające na rokowanie
Przebieg i rokowanie chemo brain są uwarunkowane wieloma czynnikami:
- Dawka chemioterapii – Wyższe dawki chemioterapii zwiększają prawdopodobieństwo występowania i nasilenia objawów chemo brain1
- Predyspozycje genetyczne – Kobiety z wyższym genetycznym ryzykiem choroby Alzheimera (genotyp APOE4) mogą być bardziej podatne na rozwój chemo brain2
- Płeć – Badania sugerują, że kora przedczołowa kobiet może być bardziej podatna na długotrwałe uszkodzenia niż u mężczyzn1
- Stan emocjonalny – Niższe wyniki funkcji poznawczych u pacjentów są powiązane z lękiem i depresją, co podkreśla potrzebę jednoczesnego leczenia trudności poznawczych i problemów emocjonalnych podczas chemioterapii2
Mechanizmy regeneracji
Po zakończeniu chemioterapii mózg ma zdolność do pewnej regeneracji poprzez proces neurogenezi (tworzenia nowych komórek nerwowych), szczególnie w obrębie hipokampa. Proces ten może pomóc naprawić część uszkodzeń spowodowanych przez chemioterapię.3 Jednakże, chemioterapia może trwale zaburzyć neurogenezę hipokampa, co przyczynia się do długotrwałych deficytów poznawczych.1
Zmiany strukturalne w mózgu spowodowane chemioterapią, w tym trwałe zmiany zarówno w istocie białej, jak i szarej, mogą utrzymywać się nawet do dwudziestu lat po zakończeniu leczenia.1 Zaburzenia poznawcze związane z chemo brain obejmują przede wszystkim zaburzenia pamięci werbalnej i wzrokowej, szybkości przetwarzania informacji oraz pamięci roboczej.3
Metody poprawy rokowania
Mimo że nie istnieją specyficzne leki zatwierdzone do leczenia chemo brain, pewne interwencje mogą pomóc w poprawie rokowania:14
- Rehabilitacja poznawcza (remediation) – ukierunkowana na pomoc w radzeniu sobie z objawami2
- Regularna aktywność fizyczna – wykazano, że poprawia funkcje wykonawcze, szybkość przetwarzania informacji i koncentrację u kobiet z chemo brain5
- Nowe terapie celowane – badania na modelach zwierzęcych wskazują, że leczenie ukierunkowane na receptory S1P może zapobiegać lub zmniejszać objawy chemo brain u zwierząt leczonych cisplatyną2
Monitorowanie i komunikacja z zespołem medycznym
Ze względu na brak specyficznych testów diagnostycznych dla chemo brain, rozpoznanie opiera się głównie na objawach zgłaszanych przez pacjentów. Osoby z rakiem, które doświadczają tych objawów, często uzyskują wyniki w normie w standardowych testach pamięci.3 Dlatego kluczowa jest otwarta komunikacja z personelem medycznym dotycząca wszystkich doświadczanych trudności poznawczych.3
Zaleca się konsultację lekarską w przypadku utrzymujących się trudności poznawczych, takich jak problemy z pamięcią, trudności z koncentracją lub uczucie „mgły umysłowej” podczas lub po leczeniu onkologicznym.4 Zespół medyczny może zlecić badania krwi, badania obrazowe mózgu lub inne testy w celu wykluczenia innych przyczyn objawów.4
Perspektywy badawcze
Nadal trwają badania nad dokładnymi mechanizmami powstawania chemo brain oraz metodami jego zapobiegania i leczenia.2 Przyszłe badania na modelach zwierzęcych mogą pomóc wyjaśnić molekularne mechanizmy i behawioralne następstwa pediatrycznego chemo brain.2
W świetle najnowszych badań, mechanizm i rola zmian związanych ze starzeniem się wywołanych przez leczenie przeciwnowotworowe wymaga dokładniejszej analizy, ponieważ pozwoli to na opracowanie strategii zapobiegania i łagodzenia neurodegeneracji i starzenia wywołanego leczeniem.3
Wnioski prognostyczne
Podsumowując, rokowanie w chemo brain jest zróżnicowane – większość pacjentów doświadcza poprawy w ciągu 1-3 lat po zakończeniu leczenia, jednak u części osób deficyty poznawcze mogą utrzymywać się dłużej. Badania wskazują, że chemo brain dotyka do 75% pacjentów onkologicznych podczas leczenia, przy czym 35% zgłasza objawy po zakończeniu terapii.3
Aktualnie nie istnieje specyficzne lekarstwo na chemo brain, ale dostępne są strategie, które mogą pomóc złagodzić jego objawy i poprawić funkcje poznawcze.5 Z czasem większość pacjentów znajduje sposoby na ułatwienie koncentracji i radzenie sobie z objawami. Do momentu poprawy, ważne jest zrozumienie, że jest to powszechny problem, który prawdopodobnie ulegnie poprawie wraz z upływem czasu.1

Our analysis focused on the hippocampus and prefrontal cortex (PFC) and was based on their pivotal roles in memory, learning, and executive functions. […] The results show that the PFCs of females may be more vulnerable than those of males in the long-term because the significant changes observed in females at 3 weeks post-exposure to MMC were not apparent in males. […] Given that chemotherapy exposure leads to molecular epigenetic changes, analyzing neuroanatomical and behavioral post-chemotherapy outcomes is an interesting area for future study. […] Chemo brain is hypothesized to manifest itself in tumor-bearing mice and is more pronounced in treated animals than in untreated ones, whereas the presence of a tumor itself also affects molecular networks in the brain. […] As highlighted at the recent conference on biomedical innovations for healthy longevity, the mechanism and role of cancer treatment-caused aging-related changes need to be analyzed because it will allow the development of strategies for the prevention and mitigation of treatment-induced neurodegeneration and aging.

- #1 Chemotherapy-Induced Cognitive Impairment and Hippocampal Neurogenesis: A Review of Physiological Mechanisms and Interventionshttps://pmc.ncbi.nlm.nih.gov/articles/PMC8657487/
Hippocampal neurogenesis is the most frequently investigated neural mechanism found to be affected by common cancer treatments, including chemotherapy. […] Chemotherapy-induced increases in reactive oxidative stress can produce cell damage that has the effect of reducing the survival of primary neural precursor cells and preventing the production of new cells, further contributing to the reduction in hippocampal neurogenesis following treatment. […] Hippocampal toxicity has emerged as a robust finding and a major factor in CICI. […] In this review of the pre-clinical literature, we discuss the neurogenic and cognitive profiles associated with common chemotherapeutic agents. […] We highlight pre- and post-treatment interventions effective in protecting against chemotherapy-induced neurogenic depletion and memory disruption following chemotherapy treatment. […] false

A wide range of cognitive deficits, including memory loss associated with hippocampal dysfunction, have been widely reported in cancer survivors who received chemotherapy. […] It is now widely recognized that common chemotherapeutic agents are capable of inducing post-treatment changes to overall brain volume, including persistent alterations in both white and gray matter which can lasting up to twenty years following treatment. […] Pre-clinical studies of the effects of anti-cancer drugs on rats and mice have replicated several common cognitive impairments observed in patients, including hippocampally-mediated memory impairment and working memory deficits. […] Multiple mechanisms contribute to cognitive impairment and hippocampal neurotoxicity in response to chemotherapy treatment, including bloodbrain barrier (BBB) disruption, neuroinflammatory responses including increased pro-inflammatory cytokines (IL-6, IL-1, TNF-) and reduced anti-inflammatory cytokines (IL-10), reduced white matter integrity, and increases in reactive oxidative stress and mitochondrial dysfunction.
