Mielofibroza
Rokowania, prognozy i postęp choroby

Mielofibroza (MF) to heterogenna choroba mieloproliferacyjna, obejmująca pierwotną (pre-PMF i overt-PMF) oraz wtórną (SMF) postać, z medianą przeżycia całkowitego (OS) wynoszącą odpowiednio około 14 lat dla pre-PMF, 7 lat dla overt-PMF i 9 lat dla SMF. Rokowanie zależy od wielu czynników klinicznych, takich jak wiek >65 lat, obecność objawów ogólnych, niedokrwistość, leukocytoza, obecność blastów, potrzeba transfuzji oraz mutacje genetyczne (JAK2, CALR, MPL, ASXL1, EZH2, SRSF2, IDH1/2). Modele prognostyczne, takie jak IPSS, DIPSS, DIPSS-plus, MIPSS70+, MYSEC-PM, GPSS, AIPSS-MF, RR6 i STR-PM, integrują dane kliniczne, cytogenetyczne i molekularne, umożliwiając precyzyjną stratifikację ryzyka i wspierając decyzje terapeutyczne, w tym kwalifikację do allogenicznego przeszczepienia komórek macierzystych (allo-SCT). Obecność dwóch lub więcej mutacji wysokiego ryzyka molekularnego (HMR) wiąże się z najgorszym przeżyciem (mediana 2,6 lat, HR 3,8, 95% CI 2,6-5,7) i skróconym przeżyciem wolnym od białaczki (HR 6,2, 95% CI 3,5-10,7).

Wprowadzenie do rokowania w mielofibrozie

Mielofibroza (MF) jest heterogenną chorobą mieloproliferacyjną charakteryzującą się znaczną zmiennością w zakresie rokowania. Możemy ją podzielić na pierwotną mielofibrozę (PMF), w tym formę przedwłóknieniową (pre-PMF) i jawną (overt-PMF), oraz wtórną mielofibrozę (SMF) wynikającą z nadpłytkowości samoistnej (ET) lub czerwienicy prawdziwej (PV). Mediana przeżycia całkowitego (OS) wynosi około 14 lat dla pre-PMF, 7 lat dla overt-PMF i 9 lat dla SMF1. Przeżycie u pacjentów z mielofibrozą może wynosić od mniej niż 2 lat do ponad 20 lat, co sprawia, że określenie rokowania jest kluczowym wyzwaniem klinicznym2.

Identyfikacja pacjentów wymagających bardziej inwazyjnych metod leczenia, takich jak przeszczepienie szpiku kostnego, stanowi krytyczną potrzebę kliniczną3. W tym celu na przestrzeni lat zaproponowano liczne modele prognostyczne, które pomagają lekarzom oszacować medianę przeżycia całkowitego (mOS) oraz przeżycie wolne od białaczki (LFS)4.

Czynniki wpływające na rokowanie

Rokowanie w mielofibrozie zależy od wielu czynników, takich jak wiek, morfologia krwi obwodowej oraz nasilenie objawów. U niektórych choroba postępuje szybciej, podczas gdy inni mogą żyć dłużej bez objawów56. Wśród najważniejszych czynników prognostycznych można wymienić:

  • Wiek powyżej 65 lat
  • Obecność objawów ogólnych (gorączka, zmęczenie, utrata apetytu)
  • Niedokrwistość
  • Podwyższona liczba białych krwinek (leukocytoza)
  • Obecność niedojrzałych komórek krwi (blastów) w krwiobiegu
  • Potrzeba przetoczeń krwi
  • Mutacje genetyczne w komórkach szpiku kostnego7

Inne istotne czynniki obejmują:

  • Zaawansowanie choroby – pacjenci z wczesnym stadium choroby mają lepsze rokowanie niż ci z zaawansowaną chorobą8
  • Określone mutacje genetyczne (JAK2, CALR, MPL) mogą znacząco wpływać na rokowanie, wpływając na progresję choroby i odpowiedź na leczenie9
  • W niektórych przypadkach mielofibroza może przekształcić się w ostrą białaczkę, co zazwyczaj wiąże się z gorszym rokowaniem10

Znaczenie profilu genetycznego

W ciągu ostatnich dwóch dekad postępy w technikach diagnostyki molekularnej, szczególnie integracja sekwencjonowania nowej generacji w laboratoriach klinicznych, zrewolucjonizowały diagnozę, klasyfikację i podejmowanie decyzji klinicznych w mielofibrozie11. Profile mutacji i nieprawidłowości cytogenetyczne zostały zintegrowane z zaawansowanymi systemami oceny prognostycznej i personalizowaną stratyfikacją ryzyka dla MF12.

Pacjenci z mutacją CALR byli młodsi, mieli wyższą liczbę płytek krwi i niższe ryzyko rozwoju niedokrwistości, małopłytkowości i znacznej leukocytozy w porównaniu z innymi podtypami13. Korzystny wpływ mutacji CALR na przeżycie i słabe przeżycie pacjentów potrójnie negatywnych w porównaniu z pacjentami z mutacją JAK2/MPL został również wykazany po allogenicznym przeszczepieniu komórek krwiotwórczych (HCT) w badaniu niemieckim14.

Niedawno zdefiniowano kategorię wysokiego ryzyka molekularnego (HMR) u pacjentów z PMF, opartą na obecności co najmniej jednego z pięciu niekorzystnych prognostycznie zmutowanych genów (ASXL1, EZH2, SRSF2 i IDH1/2)15. Obecność dwóch lub więcej mutacji była związana z najgorszym przeżyciem: mediana 2,6 lat (współczynnik ryzyka (HR) 3,8, 95% przedział ufności (CI) 2,6-5,7) w porównaniu z 7,0 lat (HR 1,9, 95% CI 1,4-2,6) dla jednej mutacji i 12,3 lat bez mutacji16. Dwie lub więcej mutacji były również związane ze skróconym przeżyciem wolnym od białaczki (HR 6,2, 95% CI 3,5-10,7)17.

Skale prognostyczne w mielofibrozie

W celu przewidywania rokowania w mielofibrozie opracowano kilka systemów oceny ryzyka, które pomagają lekarzom w podejmowaniu decyzji terapeutycznych. Poniżej przedstawiono najważniejsze z nich:

IPSS i DIPSS

Międzynarodowy System Oceny Prognostycznej (IPSS – International Prognostic Scoring System) oraz jego dynamiczna wersja (DIPSS – Dynamic International Prognostic Scoring System) to popularne skale prognostyczne używane w mielofibrozie1819. Główną zaletą DIPSS jest jego zastosowanie w dowolnym momencie klinicznego przebiegu PMF, podkreślając, jak niedokrwistość jest często wcześniejszym czynnikiem ryzyka nabywanym podczas obserwacji, manifestującym mielodepresję i będącym reprezentatywnym dla progresji choroby20.

System DIPSS uwzględnia następujące czynniki:

  • Wiek (65 lat lub starszy)
  • Objawy ogólne (niespecyficzne wskaźniki, takie jak gorączka, zmęczenie, utrata apetytu)
  • Niedokrwistość
  • Wysoka liczba białych krwinek (leukocytoza)
  • Krążące niedojrzałe komórki krwi (blasty)
  • Potrzeba transfuzji
  • Mutacje genetyczne w komórkach szpiku kostnego21

Gdy obecny jest czynnik ryzyka, system punktacji dodaje jeden punkt, a całkowity wynik określa grupę ryzyka i jest związany z przybliżoną przewidywaną długością życia:

  • 0 punktów = niskie ryzyko (15,4 lat)
  • 1 punkt = ryzyko pośrednie-1 (6,5 lat)
  • 2-3 punkty = ryzyko pośrednie-2 (2,9 lat)
  • 4 lub więcej punktów = wysokie ryzyko (1,3 lat)2223

DIPSS-plus

DIPSS-plus stanowi rozszerzenie skali DIPSS, uwzględniające dodatkowo kariotyp pacjenta. W badaniu krajowym w Japonii DIPSS-plus wykazał najwyższy wskaźnik C-Harrella (0,887), a następnie IPSS i DIPSS. Tymczasem MYSEC-PM miał najniższy wskaźnik C (0,806)24. Wyższość DIPSS-plus nad innymi modelami może wynikać z większego wpływu kariotypu na rokowanie25.

MIPSS70 i MIPSS70+

Ta sama grupa robocza zaproponowała dalsze wdrożenie skali DIPSS, zwanej MIPSS70+, w której ważone są zmiany cytogenetyczne26. Zarówno w kohortach szkoleniowych, jak i walidacyjnych, MIPSS70 i MIPSS70+ potwierdziły potencjał do przewidywania gorszego OS i wyższej częstości progresji białaczkowej u pacjentów wysokiego ryzyka27. Skala ta dowodzi, że parametry genetyczne mogą być wystarczające do zdefiniowania choroby i jej rokowania, ale ma też ograniczenie w postaci trudności w uzyskaniu tych danych28.

MYSEC-PM

MYSEC-PM to specyficzny kliniczno-molekularny model prognostyczny opracowany dla wtórnej mielofibrozy. Kohorta MYSEC, która reprezentuje obecnie największy zbiór danych pacjentów z SMF, pozwoliła na opracowanie tego modelu29. MYSEC-PM można łatwo obliczyć za pomocą nomogramu przedstawionego w oryginalnym artykule i aplikacji online30.

Inne skale prognostyczne

Istnieją również inne modele prognostyczne, takie jak:

  • GPSS (Genetics-Based Prognostic Scoring System) – zdolność GPSS do skutecznego rozróżniania między kategoriami wyższego (wysokie/pośrednie-2) i niższego (niskie/pośrednie-1) ryzyka pod względem zarówno przeżycia, jak i LFS została zwalidowana w niezależnej kohorcie 183 pacjentów z PMF31.
  • AIPSS-MF (Artificial Intelligence Prognostic Scoring System-MF) – reprezentuje pierwszy kamień milowy, który po walidacji na dużych zewnętrznych kohortach pozwoli na eksplorację nowych granic32.
  • RR6 (Response-based Prognostic Model after 6 months) – skala RR6 stosowana po 6 miesiącach terapii stanowi punkt zwrotny w ustalaniu wczesnego przejścia do innych terapii, czasami radykalnych, takich jak HSCT33.
  • STR-PM (Short-Term Ruxolitinib Prognostic Model) – może identyfikować pacjentów z wyższym ryzykiem niepowodzenia monoterapii ruksolitynibem, którzy powinni być rozważani pod kątem alternatywnych strategii pierwszej linii34.

Prognostyczne znaczenie mutacji genetycznych

Profil molekularny pacjentów z mielofibrozą ma kluczowe znaczenie dla rokowania. Niedawno zdefiniowany podpis wysokiego ryzyka molekularnego (HMR) dla pacjentów z PMF obejmuje mutacje w pięciu genach (ASXL1, EZH2, SRSF2 i IDH1/2)35. Na podstawie tych ustaleń pacjenci z PMF z mutacjami w którymkolwiek z tych pięciu genów zostali zidentyfikowani jako należący do kategorii HMR36.

Liczba niekorzystnych prognostycznie mutacji może wpływać zarówno na przeżycie, jak i odpowiedź na ruksolitynib, co ma istotne implikacje dla podejmowania decyzji klinicznych37. Wartość prognostyczna mutacji HMR w MIPSS70+ V2.0 została potwierdzona przez wyniki najnowszych badań klinicznych38.

Niższe, a nie wyższe obciążenie allelem JAK2 V617F było związane z gorszym przeżyciem i LFS w PMF39. Kilka badań wykazało, że dodatkowe mutacje inne niż związane z genami kierującymi mogą przewidywać odpowiedź kliniczną na leczenie inhibitorami JAK40. Ewolucja klonalna podczas procesu leczenia wskazuje na potrzebę monitorowania profilu mutacji w obserwacji pacjentów leczonych inhibitorami JAK41.

Rokowanie w różnych podtypach mielofibrozy

Rokowanie różni się znacząco w zależności od podtypu mielofibrozy:

Przedwłóknieniowa mielofibroza

Przedwłóknieniowa mielofibroza (pre-PMF) zwykle ma niższy wynik ryzyka niż jawna mielofibroza, ale lekarz weźmie pod uwagę wszystko i zaleci opiekę na podstawie indywidualnych potrzeb42. Mediana całkowitego przeżycia w pre-PMF wynosi około 14 lat43.

Jawna pierwotna mielofibroza

Pacjenci z jawną pierwotną mielofibrozą (overt-PMF) mają medianę przeżycia około 7 lat44. Jednak rokowanie zależy od wielu czynników indywidualnych i może się znacznie różnić między pacjentami.

Wtórna mielofibroza

Ryzyko śmiertelności wtórnej mielofibrozy (sMF) jest wyższe niż u pacjentów z rozpoznaniem pierwotnej mielofibrozy (PMF)45. Mediana przeżycia całkowitego w SMF wynosi około 9 lat46.

Transformacja białaczkowa

Transformacja w białaczkę występuje u 10% do 20% pacjentów z pierwotną mielofibrozą w ciągu pierwszych 10 lat4748. Jest to poważne powikłanie mielofibrozy, które znacząco pogarsza rokowanie.

Około 70% pacjentów z pierwotną mielofibrozą wykazuje zwiększoną gęstość najmniejszych naczyń krwionośnych szpiku kostnego, co również wiąże się ze złym przeżyciem49.

Wpływ leczenia na rokowanie

Dostępne opcje leczenia mogą znacząco wpłynąć na rokowanie pacjentów z mielofibrozą:

Inhibitory Janus kinazy (JAK)

Inhibitor JAK1/2, ruksolitynib, zatwierdzony przez Amerykańską Agencję ds. Żywności i Leków (FDA) do leczenia pacjentów z pośrednim lub wysokim ryzykiem PMF, wykazał korzyść w zakresie przeżycia dla tych kategorii pacjentów o złym rokowaniu w randomizowanych, kontrolowanych badaniach klinicznych50.

Badanie z 2022 roku, które badało wpływ leczenia na MF, wykazało również, że leczenie inhibitorami Janus Kinase (JAK) prowadziło do mediany całkowitego przeżycia wynoszącej 84 miesiące, co stanowi poprawę w porównaniu do około 64 miesięcy dekadę temu51.

Pomimo znaczącej aktywności klinicznej, 50% do 70% pacjentów przerywa stosowanie ruksolitynibu w ciągu 3 do 5 lat52. Wyniki potwierdzają, że przedłużone podawanie ruksolitynibu jest związane z poprawą OS w porównaniu z wcześniejszym przerwaniem leczenia53.

Zatwierdzenie inhibitorów JAK i innych nowych leków znacząco zmieniło krajobraz leczenia MF54. Dostępność nowych leków, które są albo zatwierdzone (tj. fedratynib, pacritinib i momelotinib), albo poddawane zaawansowanym badaniom klinicznym dla pacjentów z suboptymalną odpowiedzią lub opornością na ruksolitynib (tj. navitoclax, pelabresib i imetelstat), stała się niezwykle ważna z praktycznego punktu widzenia55.

Przeszczepienie komórek macierzystych

Jedynym potencjalnie leczniczym leczeniem mielofibrozy jest przeszczep komórek macierzystych. Wskaźnik wyleczenia za pomocą tego leczenia może wynosić od 30% do 65%, ale wiąże się to ze zwiększonym ryzykiem śmiertelności56. 3- do 5-letniego wskaźnika przeżycia dla pacjentów z mielofibrozą, którzy przeszli przeszczep komórek macierzystych, wynosi od 45% do 70%; nawrót i śmiertelność związana z przeszczepem zazwyczaj występują w ciągu pierwszych 2 lat po leczeniu57.

Zaktualizowane wytyczne EBMT/ELN sugerują rozważenie pacjentów z niskim i niektórymi pacjentami z pośrednim ryzykiem MTSS do allo-SCT58. Większość pacjentów z MF nie kwalifikuje się do allo-SCT i najczęściej otrzymuje inhibitory JAK59.

Podsumowanie prognostyczne

Mielofibroza jest chorobą o bardzo zróżnicowanym rokowaniu, które zależy od wielu czynników klinicznych, cytogenetycznych i molekularnych. Obecnie dostępnych jest kilka modeli prognostycznych, które mogą pomóc zidentyfikować pacjentów z najgorszym rokowaniem60.

Wyzwaniem dla klinicystów jest ostrożne podejście do każdego pacjenta na każdym etapie choroby, ekstrapolacja wyników skal prognostycznych i uzyskanie w ten sposób krytycznych informacji w celu zagwarantowania najlepszego podejścia terapeutycznego do najlepszego zarządzania MF61.

W ostatnich latach nastąpiła poprawa rokowania dzięki wczesnej diagnozie, stosowaniu inhibitorów JAK i ulepszonym zarządzaniu kandydatami do allo-SCT62. Zwiększona wiedza na temat biologicznego krajobrazu PMF poszerzyła liczbę dostępnych modeli przeżycia, które powinny być stosowane jednocześnie dla bardziej spersonalizowanej definicji wyniku, zwłaszcza u młodszych pacjentów63.

Ważne jest, aby pamiętać, że statystyki dotyczące przeżycia są bardzo ogólne – nie odzwierciedlają osobistego rokowania pacjenta. Ponadto rokowanie może się zmieniać w czasie, ponieważ wpływają na nie takie czynniki, jak rozpoczęcie leczenia lub zmiana na inne leczenie64.

    Myelofibrosis (MF) includes prefibrotic primary MF (pre-PMF), overt-PMF and secondary MF (SMF). Median overall survival (OS) of pre-PMF, overt-PMF and SMF patients is around 14 years, seven and nine years, respectively. […] Discoveries on the impact of the biological architecture on OS have led to the design of integrated scores to predict survival in PMF. […] Prognostic models guide prediction of OS and treatment planning in MF, therefore, their timely application is critical in the personalized approach of MF patients. […] Patients affected by MF have a significantly reduced outcome, with a median OS of 14 years, seven and nine years in pre-PMF, overt-PMF and SMF, respectively. […] Nonetheless, in recent years improvement in prognosis has been registered. […] The MYSEC cohort, that represents to date the largest dataset of SMF patients, allowed to generate a specific clinical-molecular prognostic score, the MYSEC-Prognostic Model (MYSEC-PM).

  • #5 Myelofibrosis prognosis: Life expectancy, treatment options & more
    https://www.medicalnewstoday.com/articles/myelofibrosis-prognosis
    The outlook for someone with myelofibrosis depends on factors such as age, blood cell counts, and symptoms. For some people, the condition progresses more rapidly than others. […] Therefore, the MF outlook varies significantly. […] Predicting the life expectancy of someone with MF is challenging. […] The approximate life expectancy for those with MF is as follows: 15.4 years for low risk individuals, 6.5 years for intermediate-1 (INT-1) risk individuals, 2.9 years for INT-2 risk individuals, 1.3 years for high risk individuals. […] However, while outcome data can illustrate how people with MF have fared in response to treatments, it may not precisely predict how an individual will respond. […] A person’s myelofibrosis prognosis depends on various factors, and some people remain symptom-free for many years. […] However, for those with risk factors such as being over 65 years old, having whole-body symptoms or anemia, and having specific genetic abnormalities, the outlook may be less favorable.

    https://www.healthline.com/health/myelofibrosis/prognosis-and-life-expectancy
    Life expectancy for myelofibrosis varies based on age, blood cell counts, and symptoms. Some experience rapid progression, while others may live longer without symptoms. Treatment can help extend your life span. […] Predicting the outlook for MF is difficult and depends on many factors. […] However, doctors and researchers have identified some factors that can help predict a persons outlook with MF. These factors are used in the International Prognosis Scoring System (IPSS) to help doctors predict average years of survival. […] Its important to note that these survival estimates are based on survival averages and currently available treatments. As newer treatments are developed, survival rates may also change. […] Meeting one of the factors below means the average survival rate is about six years. Meeting three or more can lower the expected survival rate to around one and almost three years.

    https://healthtree.org/myelofibrosis/community/articles/understanding-mf-prognosis
    Around 10-20% of people with myelofibrosis will progress to acute myeloid leukemia. This type of leukemia is challenging to treat and has a significant impact on a persons life. For this reason, myelofibrosis prognosis will be directly linked to the patients risk of progressing to leukemia. […] A helpful tool for doctors to assess risk is the DIPSS dynamic international prognostic scoring system, which takes into account the following factors: Age (65 or older), Symptoms (non-specific indicators like fever, fatigue, appetite loss, etc), Anemia, High white blood cell count (leukocytosis), Circulating immature blood cells (blasts), Need for transfusions, Genetic mutations in the bone marrow cells. […] These risk factors help quickly assess a patient to calculate an approximate life expectancy. However, doctors consider other factors when meeting patients and learning more about their lifestyle, habits, family history, and overall health.

    https://healthtree.org/myelofibrosis/community/what-is-the-survival-rate-for-myelofibrosis
    Myelofibrosis is a type of myeloproliferative neoplasm (MPN) with a median survival of 6 years. A median is a midpoint, which means that some people live less than six years, and about the same number of people can live longer than six years. Overall, fewer than 20% of patients with myelofibrosis are predicted to survive longer than 10 years. However, current advancements in myelofibrosis treatment are improving patient prognosis. […] The prognosis for myelofibrosis varies widely depending on several factors: […] Patients with early-stage disease generally have a better prognosis than those with advanced-stage disease. […] Age can impact prognosis, with older patients potentially facing more complications and challenges in managing the disease. […] Prognosis is influenced by the severity of symptoms and complications, such as an enlarged spleen or recurrent infections.

[…] Advances in treatment options, such as targeted therapies and bone marrow transplantation, have led to better outcomes for many people with myelofibrosis. However, individual responses to treatment can vary, and how well a person responds to and tolerates the treatment can greatly impact their prognosis. […] In some cases, myelofibrosis can transform into acute leukemia, which typically has a poorer prognosis. […] Older age correlates with shorter survival in patients with myelofibrosis.

    We recently defined a high-molecular risk category (HMR) in primary myelofibrosis (PMF), based on the presence of at least one of the five prognostically detrimental mutated genes (ASXL1, EZH2, SRSF2 and IDH1/2). […] The presence of two or more mutations predicted the worst survival: median 2.6 years (hazard ratio (HR) 3.8, 95% confidence interval (CI) 2.6-5.7) vs 7.0 years (HR 1.9, 95% CI 1.4-2.6) for one mutation vs 12.3 years for no mutations. […] Two or more mutations were also associated with shortened leukemia-free survival (HR 6.2, 95% CI 3.5-10.7), also Mayo validated. […] We conclude that the number of prognostically detrimental mutations provides added value in the combined molecular and clinical prognostication of PMF.

    Myelofibrosis (MF) is divided into two categories, namely primary MF (PMF) and secondary MF arising from essential thrombocythemia (ET) or polycythemia vera (PV), so-called PET-MF or PPV-MF, respectively. […] However, discrepancies in the application of PMF prognostic scoring systems, such as the International Prognostic Scoring System (IPSS) and dynamic IPSS (DIPSS) for patients with PET/PPV-MF have been reported, and the prognostic scoring systems for PET/PPV-MF has been developed. […] We determined if the known prognostic factors used in the IPSS, DIPSS, DIPSS-plus, and the myelofibrosis secondary to PV and ET prognostic model (MYSEC-PM) were predictive of shortened survival in patients with PET/PPV-MF. […] This suggests that these three factors have a stronger impact on survival than other factors.

    Myelofibrosis is different for different people. For some its slow growing and may not need treatment right away. Others may need treatment more quickly. […] Your prognosis (what may happen in the future) is personal to you. It will depend on lots of things: your blood counts, your symptoms, your age, your overall health, including other conditions you may have, the genetic mutation thats causing the MF. […] Based on these things, your doctor may calculate a risk score. There are a few different systems in use but generally they come up with a risk score of low, intermediate-1, intermediate-2 or high. This gives doctors an idea of your prognosis and helps them decide what treatment you need. If your risk score is low or intermediate-1, you may not need treatment at all. […] Prefibrotic myelofibrosis (MF) usually has a lower risk score than overt MF, but your doctor will take everything into account and recommend care based on your individual needs. […] Its important to understand that statistics about survival are very general they dont reflect your personal prognosis.

    Myelofibrosis (MF) includes prefibrotic primary MF (pre-PMF), overt-PMF and secondary MF (SMF). Median overall survival (OS) of pre-PMF, overt-PMF and SMF patients is around 14 years, seven and nine years, respectively. […] Discoveries on the impact of the biological architecture on OS have led to the design of integrated scores to predict survival in PMF. […] Prognostic models guide prediction of OS and treatment planning in MF, therefore, their timely application is critical in the personalized approach of MF patients. […] Patients affected by MF have a significantly reduced outcome, with a median OS of 14 years, seven and nine years in pre-PMF, overt-PMF and SMF, respectively. […] Nonetheless, in recent years improvement in prognosis has been registered. […] The MYSEC cohort, that represents to date the largest dataset of SMF patients, allowed to generate a specific clinical-molecular prognostic score, the MYSEC-Prognostic Model (MYSEC-PM).

    Around 10-20% of people with myelofibrosis will progress to acute myeloid leukemia. This type of leukemia is challenging to treat and has a significant impact on a persons life. For this reason, myelofibrosis prognosis will be directly linked to the patients risk of progressing to leukemia. […] A helpful tool for doctors to assess risk is the DIPSS dynamic international prognostic scoring system, which takes into account the following factors: Age (65 or older), Symptoms (non-specific indicators like fever, fatigue, appetite loss, etc), Anemia, High white blood cell count (leukocytosis), Circulating immature blood cells (blasts), Need for transfusions, Genetic mutations in the bone marrow cells. […] These risk factors help quickly assess a patient to calculate an approximate life expectancy. However, doctors consider other factors when meeting patients and learning more about their lifestyle, habits, family history, and overall health.

  • #50 Prognosis of primary myelofibrosis in the genomic era
    https://pmc.ncbi.nlm.nih.gov/articles/PMC4987499/
    Currently, prognostication in primary myelofibrosis (PMF) relies on the International Prognostic Scoring System (IPSS), dynamic IPSS (DIPSS) and DIPSS-plus, which incorporate age, blood counts, constitutional symptoms, circulating blasts, red cell transfusion need and karyotype. […] The number of prognostically detrimental mutations may affect both survival and response to ruxolitinib, which has significant implications for clinical decision making. […] Recently, the Janus kinase (JAK) 1/2 inhibitor, ruxolitinib, approved by the Food and Drug Administration (FDA) for the treatment of patients with intermediate or high risk patients with PMF, post-PV or post-ET MF, has demonstrated a survival benefit for these poor risk categories of patients in randomized, controlled clinical trials. […] A low, rather than high, JAK2 V617F allele burden has been associated with inferior survival and LFS in PMF.

    People who dont meet the above criteria, excluding age, are considered in the low risk category and have a median survival of over 15 years. […] A 2022 study that examined the effect of treatment on MF also found that treating with Janus Kinase (JAK) inhibitors led to a median overall survival of 84 months, which is an improvement from about 64 months a decade ago. […] A persons outlook with myelofibrosis can vary from around 1 year to more than 15 years, depending on individual risk factors and disease progression. […] Treatment may help reduce symptoms, slow disease progression, and improve your quality of life.

    It is undeniable that the current molecular genetic profiling results fall short of capturing all prognostically significant factors in MF. […] The treatment strategy depends on the clinical presentation, risk stratification, prediction of prognosis, and transplant-specific risk (MTSS) to select patients eligible for HSCT. […] The approval of JAK inhibitors and other novel agents has significantly changed the treatment landscape of MF. […] Several studies have demonstrated that additional non-driver mutations may predict clinical response to JAK inhibitor treatment. […] Clonal evolution during the treatment process indicates the need to monitor the mutation profile in the follow-up of patients treated with JAK inhibitors. […] The prospect of specific therapies that induce complete molecular genetic remission, analogous to tyrosine kinase inhibitor therapy for BCR::ABL1-positive CML, remains a compelling approach in the pursuit of the best clinical outcomes for MF.

    Myelofibrosis is different for different people. For some its slow growing and may not need treatment right away. Others may need treatment more quickly. […] Your prognosis (what may happen in the future) is personal to you. It will depend on lots of things: your blood counts, your symptoms, your age, your overall health, including other conditions you may have, the genetic mutation thats causing the MF. […] Based on these things, your doctor may calculate a risk score. There are a few different systems in use but generally they come up with a risk score of low, intermediate-1, intermediate-2 or high. This gives doctors an idea of your prognosis and helps them decide what treatment you need. If your risk score is low or intermediate-1, you may not need treatment at all. […] Prefibrotic myelofibrosis (MF) usually has a lower risk score than overt MF, but your doctor will take everything into account and recommend care based on your individual needs. […] Its important to understand that statistics about survival are very general they dont reflect your personal prognosis. Also, your prognosis can change over time because it is affected by things like starting treatment or changing to a different treatment.
