Przewlekła białaczka szpikowa
Epidemiologia
Przewlekła białaczka szpikowa (CML) stanowi około 15% białaczek u dorosłych i charakteryzuje się obecnością chromosomu Philadelphia oraz genu fuzyjnego BCR-ABL1. Roczna zachorowalność globalnie wynosi 0,7-1,3/100 000, z wyższymi wskaźnikami w USA (1,4-2,2/100 000) i regionach takich jak Pernambuco w Brazylii (3,4/100 000). Mediana wieku diagnozy w Europie to 57-60 lat, a w USA 64-66 lat, z wyraźnym wzrostem zachorowalności wraz z wiekiem i przewagą mężczyzn (stosunek 1,2-1,7:1). Chorobowość szacowana jest na 10-15/100 000, a dzięki inhibitorom kinazy tyrozynowej (TKI) pięcioletnie przeżycie wzrosło z 30-40% do 70-90%. Diagnostyka opiera się na wykrywaniu mutacji BCR-ABL1, a monitoring molekularny (RQ-PCR) jest standardem w ocenie odpowiedzi na leczenie i wykrywaniu nawrotów. Większość pacjentów diagnozowana jest w fazie przewlekłej, z łagodnym przebiegiem, natomiast fazy akceleracji i blastyczna charakteryzują się agresywnym przebiegiem i gorszym rokowaniem.

Epidemiologia przewlekłej białaczki szpikowej
Przewlekła białaczka szpikowa (CML, chronic myeloid leukemia) stanowi około 15% wszystkich białaczek u dorosłych. Jest względnie rzadką chorobą nowotworową krwi i szpiku kostnego, charakteryzującą się obecnością chromosomu Philadelphia i genu fuzyjnego BCR-ABL1.12 Choroba ta występuje głównie u osób dorosłych, rzadko obserwuje się ją u dzieci, które stanowią zaledwie 2-3% wszystkich przypadków CML.34
Zachorowalność na CML na świecie
Roczna zachorowalność na przewlekłą białaczkę szpikową na świecie waha się w zakresie 0,7-1,3 przypadków na 100 000 mieszkańców, z niewielkimi różnicami geograficznymi.56 W Stanach Zjednoczonych wskaźnik ten jest nieco wyższy i wynosi około 1,4-2,2 przypadków na 100 000 osób, przy czym szacuje się, że w 2025 roku zdiagnozowanych zostanie około 9 560 nowych przypadków CML (5 610 u mężczyzn i 3 950 u kobiet).78 W Europie, zgodnie z danymi z rejestrów populacyjnych, wskaźniki zachorowalności są zbliżone do średniej światowej i wynoszą 0,7-1,0 na 100 000 mieszkańców.9
W Wielkiej Brytanii rocznie diagnozuje się około 840 nowych przypadków przewlekłej białaczki szpikowej, co stanowi mniej niż 1% wszystkich nowych przypadków nowotworów.10 W Kanadzie w 2019 roku zdiagnozowano 665 nowych przypadków CML (390 mężczyzn i 270 kobiet).11 W Australii każdego roku diagnozuje się około 330 nowych przypadków CML, co stanowi około 0,03% wszystkich diagnozowanych nowotworów.12
Warto zauważyć, że w niektórych regionach świata obserwuje się wyższe wskaźniki zachorowalności. Przykładowo, w stanie Pernambuco w Brazylii odnotowano wskaźnik zachorowalności na poziomie 3,4 przypadków na 100 000 mieszkańców.1314 Natomiast w Tunezji roczna zachorowalność wynosi 0,79 na 100 000 mieszkańców.15
Trendy demograficzne i dystrybucja wiekowa
Mediana wieku w momencie diagnozy CML wynosi około 57-60 lat w Europie, natomiast w Stanach Zjednoczonych jest nieco wyższa i wynosi 64-66 lat.161718 Choroba może wystąpić w każdym wieku, jednak obserwuje się wyraźny wzrost zachorowalności wraz z wiekiem. Szczyt zachorowalności przypada na przedział wiekowy 55-60 lat.19
W populacji pediatrycznej CML jest wyjątkowo rzadka, zwłaszcza w pierwszych trzech latach życia. Baza danych SEERS pokazuje stale rosnącą częstość występowania od 0,7 przypadków w grupie wiekowej 1-4 lat do 4,3 przypadków na 1 000 000 w wieku 15-19 lat.20 U dorosłych ryzyko wystąpienia CML wzrasta wraz z wiekiem, a najwyższe wskaźniki zachorowalności obserwuje się u osób w wieku 75-84 lat.21
W niektórych regionach świata, szczególnie w Azji, mediana wieku zachorowania na CML jest niższa i wynosi 35-45 lat, w porównaniu do 60 lat w populacji kaukaskiej.22 Dane z Malezji wskazują, że średni wiek diagnozy wynosi 40,87 ± 16,45 lat, a zakres wiekowy waha się od 13 do 81 lat.23
Różnice płciowe i etniczne
Przewlekła białaczka szpikowa występuje częściej u mężczyzn niż u kobiet, przy czym stosunek płci męskiej do żeńskiej wynosi zazwyczaj 1,2-1,7:1.2425 W Stanach Zjednoczonych wskaźniki zachorowalności na 100 000 mieszkańców wynoszą 2,5 u mężczyzn w porównaniu do 1,5 u kobiet.26 W Wielkiej Brytanii około 55% przypadków CML występuje u mężczyzn, a 45% u kobiet.27
Dane dotyczące różnic etnicznych w zachorowalności na CML są ograniczone, jednak niektóre badania sugerują, że w Anglii wskaźniki zachorowalności są wyższe w grupie etnicznej azjatyckiej w porównaniu do grupy etnicznej białej.28 Nie zaobserwowano jednak wyraźnych zależności geograficznych, etnicznych czy ekonomicznych związanych z występowaniem CML.29
Czynniki ryzyka
Przyczyny rozwoju przewlekłej białaczki szpikowej nie są w pełni poznane. U większości pacjentów nie identyfikuje się jednoznacznych czynników ryzyka. Znane czynniki zwiększające ryzyko rozwoju CML obejmują:
- Ekspozycję na wysokie dawki promieniowania jonizującego – wyższe wskaźniki zachorowalności obserwowano u osób, które przeżyły wybuch bomby atomowej w Japonii w 1945 roku oraz wśród mieszkańców terenów wokół elektrowni jądrowej w Czarnobylu303132
- Wiek – ryzyko zachorowania wzrasta wraz z wiekiem33
- Płeć męska – nieco wyższe ryzyko występuje u mężczyzn34
Palenie tytoniu jest wskazywane jako potencjalny czynnik przyczyniający się do zgonów i niepełnosprawności związanej z CML, choć jego rola w patogenezie choroby wymaga dalszych badań.35
Chorobowość i przeżycie
Chorobowość (rozpowszechnienie) przewlekłej białaczki szpikowej jest mniej dokładnie zbadana niż zachorowalność, ale szacuje się, że wynosi około 10-15 przypadków na 100 000 mieszkańców.3637 W ostatnich dziesięcioleciach obserwuje się stały wzrost chorobowości, co jest wynikiem dramatycznej poprawy przeżywalności pacjentów z CML, głównie dzięki wprowadzeniu inhibitorów kinazy tyrozynowej (TKI).38
Przed erą inhibitorów kinazy tyrozynowej, pięcioletnie przeżycie pacjentów z CML wynosiło około 30-40%. Wprowadzenie TKI radykalnie zmieniło rokowanie i obecnie pięcioletnie przeżycie pacjentów osiąga 70-90%.39 Badania pokazują, że u pacjentów leczonych inhibitorami kinazy tyrozynowej średnia długość życia zbliża się do średniej populacyjnej, szczególnie u osób młodszych.4041
W Stanach Zjednoczonych szacuje się, że w 2025 roku z powodu CML umrze około 1 290 osób (740 mężczyzn i 550 kobiet).42 Współczynnik umieralności wynosi 0,3 na 100 000 mieszkańców rocznie.43 W Kanadzie w 2022 roku odnotowano 140 zgonów z powodu CML (73 mężczyzn i 67 kobiet).44
Mimo znacznej poprawy wyników leczenia, nadal obserwuje się różnice w przeżywalności w zależności od wieku. U pacjentów powyżej 50. roku życia występuje zwiększona śmiertelność w porównaniu do populacji ogólnej, podczas gdy przeżywalność młodszych pacjentów odpowiada przeżywalności populacji ogólnej.45
Trendy epidemiologiczne i nadzór
Analiza danych epidemiologicznych wskazuje, że zachorowalność na CML utrzymuje się na stabilnym poziomie przez ostatnie dekady.4647 Jednak w niektórych regionach, zwłaszcza w Stanach Zjednoczonych, obserwuje się niewielki wzrost zachorowalności w tempie około 1,0-1,2% rocznie w ostatniej dekadzie.4849
Jednocześnie wskaźniki umieralności z powodu CML systematycznie spadają. W Stanach Zjednoczonych odnotowano średni roczny spadek umieralności o 0,7% w latach 2014-2023.50 W Wielkiej Brytanii od wczesnych lat 70. XX wieku współczynniki umieralności z powodu CML zmniejszyły się o prawie trzy czwarte (73%).51

Znaczenie rejestrów populacyjnych w nadzorze nad CML
Krajowe i regionalne rejestry populacyjne stanowią niezbędne narzędzia do badań epidemiologicznych nad przewlekłą białaczką szpikową.5253 Rejestry te, pod warunkiem dokładnej diagnostyki i pełnego pokrycia populacji docelowej, dostarczają cennych danych na temat zachorowalności, chorobowości, wyników leczenia i przeżywalności pacjentów.
Rejestry CML z bardziej kompleksową sprawozdawczością mogą również dostarczać uzupełniających danych o wynikach leczenia, które są komplementarne do tych uzyskanych z badań klinicznych.54 Jest to szczególnie istotne w erze inhibitorów kinazy tyrozynowej, które radykalnie zmieniły przebieg i rokowanie w CML.
Przykładem takiego rejestru jest Andaluzyjski Rejestr CML (RALMC) w Hiszpanii, który dostarcza danych o epidemiologii CML w warunkach rzeczywistych, poza badaniami klinicznymi.5556 Podobne inicjatywy istnieją w wielu krajach europejskich i na świecie.
Wyzwania i kierunki dalszych badań
Mimo znacznego postępu w leczeniu przewlekłej białaczki szpikowej, wciąż istnieją obszary wymagające dalszych badań epidemiologicznych:
- Wpływ czynników socjoekonomicznych i systemów opieki zdrowotnej na długoterminowe wyniki leczenia5758
- Potencjalne zwiększone ryzyko rozwoju wtórnych nowotworów u pacjentów z CML59
- Identyfikacja niekorzystnych efektów ubocznych związanych z długotrwałym stosowaniem inhibitorów kinazy tyrozynowej60
- Różnice w przebiegu klinicznym i wynikach leczenia między pacjentami pediatrycznymi a dorosłymi61
- Poszukiwanie nowych biomarkerów prognostycznych, takich jak krążące RNA (np. hsa_circ_0006010 i hsa_circ_0002903), które mogą służyć jako narzędzia diagnostyczne, nadzorcze i prognostyczne dla progresji choroby6263
Badacze poszukują również odpowiedzi na pytanie, czy możliwe jest przerwanie leczenia inhibitorami kinazy tyrozynowej u niektórych pacjentów z długotrwałą remisją molekularną, co jest przedmiotem trwających badań klinicznych.64
Nadzór i monitorowanie przewlekłej białaczki szpikowej
Nadzór nad przewlekłą białaczką szpikową obejmuje systematyczne zbieranie danych o zachorowaniach, monitorowanie trendów epidemiologicznych oraz ocenę skuteczności leczenia. Kluczowym elementem nadzoru jest właściwa diagnostyka przypadków CML.
Diagnostyka i monitoring molekularny
Krajowe i międzynarodowe wytyczne hematologiczne/onkologiczne zalecają badanie mutacji BCR-ABL dla ostatecznej diagnozy przewlekłej białaczki szpikowej, co umożliwia odpowiednie leczenie inhibitorem kinazy tyrozynowej (TKI).65 W badaniu populacyjnym przeprowadzonym w Stanach Zjednoczonych zidentyfikowano 685 przypadków CML, z których 55% (374) miało udokumentowany test genu BCR-ABL, a 96% (360) z tych testów było pozytywnych dla genu BCR-ABL.66
Charakterystyczną cechą CML jest chromosom Philadelphia (Ph), który występuje w około 90% przypadków. Wśród osób z negatywnym wynikiem badania chromosomu Ph, od jednej trzeciej do połowy pacjentów ma pozytywny wynik testu na nieprawidłowy gen lub nieprawidłowe białko związane z chromosomem, gdy stosuje się bardziej czułe badania, takie jak fluorescencyjna hybrydyzacja in situ (FISH) lub reakcja łańcuchowa polimerazy (PCR).67
Obecnie monitoring molekularny jest standardem opieki nad pacjentami z CML, umożliwiając ocenę odpowiedzi na leczenie i wczesne wykrycie nawrotu choroby. Regularne badania ilościowe PCR w czasie rzeczywistym (RQ-PCR) pozwalają na monitorowanie poziomu transkryptu BCR-ABL1 we krwi obwodowej.68
Fazy choroby i ich monitorowanie
Większość pacjentów (85-90%) jest diagnozowana w fazie przewlekłej CML, a w ostatnich latach około 40% pacjentów zostało zdiagnozowanych przed wystąpieniem jakichkolwiek objawów, dzięki przypadkowo wykrytym nieprawidłowościom w badaniu krwi.69 W fazie przewlekłej choroba charakteryzuje się względnie łagodnym przebiegiem, z nadmierną produkcją dojrzałych i dojrzewających neutrofili, bazofili i eozynofili.70
Rzadziej pacjenci prezentują początkowo bardziej agresywne stadia CML nazywane fazą akceleracji (AP) i/lub fazą blastyczną (BP). Te zaawansowane stadia CML charakteryzują się obecnością coraz bardziej niedojrzałych komórek krwi we krwi i szpiku kostnym, pogarszającymi się objawami i dodatkowymi nieprawidłowościami cytogenetycznymi.71
Według najnowszej definicji WHO, progresja CML dzieli się na dwie fazy:
- Fazę akceleracji (AP) z ciągłą lub zwiększającą się splenomegalią, utrzymującą się lub zwiększającą się leukocytozą
- Fazę blastyczną (BP), która reprezentuje ostrą białaczkę i jest stanem zagrażającym życiu72
Odpowiedź cytogenetyczna definiowana jest jako zmniejszenie odsetka komórek Ph+ ocenianych poprzez analizę pozostałych metafaz za pomocą konwencjonalnej lub molekularnej cytogenetyki.73
Znaczenie monitorowania dla zdrowia publicznego
Nadzór epidemiologiczny nad CML ma kluczowe znaczenie dla zdrowia publicznego z kilku powodów:
- Umożliwia śledzenie trendów zachorowalności i umieralności z powodu CML
- Pozwala na ocenę wpływu nowych terapii na przeżywalność pacjentów
- Dostarcza danych do planowania zasobów opieki zdrowotnej
- Pomaga w identyfikacji potencjalnych czynników ryzyka środowiskowego
- Wspiera badania nad różnicami w wynikach leczenia między różnymi grupami demograficznymi i regionami geograficznymi74
Globalne badanie obciążenia chorobami (GBD) wykazało, że globalne obciążenie CML zmniejszyło się w latach 1990-2017. Wskaźniki zachorowalności, zgonów i DALY (lata życia skorygowane niepełnosprawnością) gwałtownie spadły w krajach o wysokim i średnio-wysokim poziomie rozwoju społeczno-demograficznego (SDI), a nieznacznie spadły w pozostałych trzech kwintylach SDI.75
Jednocześnie liczba przypadków zachorowań, zgonów i DALY z powodu CML wykazywała tendencję wzrostową w krajach o średnim, średnio-niskim i niskim SDI między 1990 a 2017 rokiem z powodu wzrostu populacji.76 Wskazuje to na potrzebę wzmocnienia systemów nadzoru i dostępu do nowoczesnych terapii w krajach rozwijających się.
Wyzwania w nadzorze nad CML
Nadzór epidemiologiczny nad przewlekłą białaczką szpikową napotyka na szereg wyzwań:
- Ograniczona dostępność wiarygodnych danych epidemiologicznych w krajach o niskim i średnim dochodzie77
- Różnice metodologiczne w zbieraniu i analizie danych między rejestrami
- Niepełne raportowanie przypadków CML do rejestrów
- Trudności w długoterminowym śledzeniu pacjentów
- Ograniczenia w ocenie wpływu nowych terapii na przeżywalność w warunkach rzeczywistych78
Przykładem metodologicznych ograniczeń może być Andaluzyjski Rejestr CML (RALMC), gdzie udział pacjentów jest dobrowolny i wymaga pisemnej zgody.79
Perspektywy na przyszłość
Przyszłość nadzoru epidemiologicznego nad CML obejmuje kilka obiecujących kierunków:
- Rozwój bardziej kompleksowych i ujednoliconych systemów rejestracji przypadków CML na poziomie krajowym i międzynarodowym
- Integracja danych molekularnych i genetycznych z danymi epidemiologicznymi
- Wykorzystanie nowych biomarkerów do monitorowania progresji choroby80
- Ocena długoterminowego wpływu inhibitorów kinazy tyrozynowej na przeżywalność i jakość życia pacjentów
- Badanie możliwości bezpiecznego przerwania leczenia u wybranych pacjentów81
- Monitorowanie potencjalnego zwiększonego ryzyka wtórnych nowotworów u pacjentów z CML82
Oczekuje się, że chorobowość CML będzie nadal rosnąć ze względu na postępy terapeutyczne, co podkreśla znaczenie ciągłej oceny przestrzegania wytycznych dotyczących CML i wyników leczenia.83
Dane epidemiologiczne wskazują, że przeżycie pacjentów z CML będzie nadal się poprawiać, zbliżając się do przeżycia populacji ogólnej, szczególnie u młodszych pacjentów.84 Jednakże nadal istnieje potrzeba poprawy wyników leczenia u starszych pacjentów oraz w krajach o ograniczonym dostępie do nowoczesnych terapii.

Chronic myeloid leukemia (CML; previously called chronic myelogenous leukemia, chronic myelocytic leukemia, or chronic granulocytic leukemia) is a myeloproliferative neoplasm that manifests uncontrolled proliferation of mature and maturing granulocytes in blood and bone marrow. CML accounts for approximately 15 percent of adult leukemias. The median age at diagnosis is in the sixties, but CML can occur at any age. Most patients present with chronic phase (CP) CML, which is a relatively indolent disorder of excessive mature and maturing neutrophils, basophils, and eosinophils, with or without splenomegaly and/or constitutional symptoms. Up to one-half of patients with CP CML are asymptomatic at diagnosis. In regions with limited access to medical care, patients often present with more advanced disease.

Chronic myeloid leukemia (CML) is a type of blood cancer that affects hematopoietic stem cells and is often characterized by the presence of the Philadelphia chromosome. […] The median age of people affected is approximately 56 years and it accounts for about 15-20% of leukemia in adults. CML incidence worldwide varies from 0.6 to 2.8/100,000 individuals per year. […] The WHOs recent definition of CML stages divides disease progression into two phases: An accelerated phase (AP) with continuous or increasing splenomegaly, persistent or increasing leukocytosis. […] Cytogenetic and molecular biology techniques play a key role in the detection of chromosomal abnormalities and mutations involved in the oncogenesis of the disease. […] As for the treatment of CML, advances in science have led to the introduction of tyrosine kinase inhibitors, as a targeted therapy, which acts directly on the kinase activity of the BCR-ABL oncoprotein.
- #3 Definition, Epidemiology, Pathophysiology, and Essential Criteria for Diagnosis of Pediatric Chronic Myeloid Leukemiahttps://www.mdpi.com/2072-6694/13/4/798
CML usually presents at a median age of 60 years in Caucasians, but at younger age (35â45 years) in Asians. It is rare in children contributing only 2â3% of all pediatric leukemia cases. The global incidence rate of CML is 15/1,000,000 per year with a male to female ratio of 1.34 while the age-adjusted incidence rate for the age group <18 years is 1.0 per 1,000,000. In the first three years of life pediatric CML is extremely rare. The SEERS database showing pooled data on all myeloproliferative diseases at childhood age lists a continuously increasing incidence rate from 0.7 cases in the age group 1 to 4 years up to 4.3 cases per 1,000,000 at 15 to 19 years. From the authorsâ experience, myeloproliferative diseases besides CML like essential thrombocytosis, polycythemia vera and myelofibrosis are more than 10-fold less frequent than CML in the first two decades of life. Therefore, the SEERS data give a rather detailed impression on the continuous increase in the incidence of CML especially in the 2nd decade of life.

Chronic myeloid leukemia (CML) rarely occurs in the first two decades of life, accounting for 2% to 3% of leukemias in children and adolescents. […] Because of a lack of robust clinical study evidence, management of CML in children is not standardized and often follows guidelines developed for adults. […] Children and young adults tend to have a more aggressive clinical presentation than older adults, and recent data indicate that some genetic differences exist in pediatric and adult CML. […] This review aims to outlines the morphological, genetic and immuno-phenotypical findings of pediatric CML, and to recommend a uniform approach for the diagnostic procedures to be applied and for standardized treatment.

National and regional population-based registries are, provided diagnostic accuracy and full coverage of the target population, indispensible tools for epidemiological research. Chronic myeloid leukaemia (CML) registries with more comprehensive reporting may also provide complementary data on treatment outcome to those obtained from clinical trials. Reports from several European CML registries consistently show a crude annual incidence of 0.7-1.0/100,000, a median age at diagnosis of 57-60 years and a male/female ratio of 1.2-1.7. The incidence of CML has been stable over time. Worldwide, variations in the reported incidence of CML may be due to methodological issues, but a true difference between different geographical areas and/or ethnical subgroups cannot be excluded. The prevalence of CML is not well known but has been estimated to be 10-12/100,000 inhabitants with a steady increase due to the dramatic improvement in survival of these patients.

National and regional population-based registries are, provided diagnostic accuracy and full coverage of the target population, indispensable tools for epidemiological research. […] Reports from several European CML registries consistently show a crude annual incidence of 0.71.3/100,000, median age at diagnosis of 5660 years and a male/female ratio of 1.21.7. […] The incidence of CML has been stable over time. […] The prevalence of CML is less well known but has been estimated to 1520/100,000 inhabitants with a steady increase due to the profound improvement in survival of these patients. […] The impact of socioeconomic factors and health-care settings related to long-term outcome, a possible increased risk of secondary cancer development and identification of adverse off-target effects related to the continuous administration of tyrosine kinase inhibitors are among areas of ongoing epidemiological research in CML.
- #7 Key Statistics for Chronic Myeloid Leukemia | American Cancer Societyhttps://www.cancer.org/cancer/types/chronic-myeloid-leukemia/about/statistics.html
The American Cancer Society’s estimates for chronic myeloid leukemia (CML) in the United States for 2025 are: About 9,560 new cases will be diagnosed with CML (5,610 in men and 3,950 in women) […] About 1,290 people will die of CML (740 men and 550 women) […] About 15% of all new cases of leukemia are chronic myeloid leukemia. About 1 person in 526 will get CML in their lifetime in the United States. […] The average age of people diagnosed with CML is around 64 years. Almost half of all cases are diagnosed in people 65 and older. This type of leukemia mainly affects adults, and is rarely seen in children.
- #8 Chronic Myelogenous Leukemia – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK531459/
Chronic myelogenous leukemia (CML) has a worldwide annual incidence rate of 0.87 people per 100,000, increasing with age up to 1.52 in patients older than 70. There is a slight predominance in men, and the median age of diagnosis is 56. In the United States, the annual incidence rate between 2009 and 2013 was 1.4 and 2.2 per 100,000 for women and men, respectively. Estimates for 2018 were 8490 new cases of CML and 1090 estimated deaths. […] There is an increased incidence of CML among atomic bomb survivors; however, the predisposing risk factors are unknown.

The importance of socio-economic factors and health-care setting for outcome and the possible increased risk of secondary cancer in CML are areas of ongoing research.
- #10 Chronic myeloid leukaemia (CML) statistics | Cancer Research UKhttps://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-cancer-type/leukaemia-cml
There are around 840 new chronic myeloid leukaemia cases in the UK every year, that’s more than 2 every day (2017-2019). […] Chronic myeloid leukaemia accounted for less than 1% of all new cancer cases in the UK in 2017-2019. […] In females in the UK, chronic myeloid leukaemia accounted for around 370 new cancer cases every year (2017-2019). […] In males in the UK, chronic myeloid leukaemia accounted for around 460 new cancer cases every year (2017-2019). […] Incidence rates for chronic myeloid leukaemia in the UK are highest in people aged 90+ (2017-2019). […] Each year around a quarter (24%) of all new chronic myeloid leukaemia cases in the UK are diagnosed in people aged 75 and over (2017-2019). […] Since the early 1990s, chronic myeloid leukaemia incidence rates have decreased by around a quarter (26%) in the UK. Rates in females have decreased by a fifth (20%), and rates in males have decreased by more than a third (35%) (2017-2019).

Chronic myeloid leukaemia (CML) is a type of cancer that affects the blood and bone marrow. In CML the bone marrow produces too many white cells, called granulocytes. These cells (sometimes called blasts or leukaemic blasts) gradually crowd the bone marrow, interfering with normal blood cell production. They also spill out of the bone marrow and circulate around the body in the bloodstream. Because they are not fully mature, they are unable to work properly to fight infections. Over time, a shortage of red cells and platelets can cause anaemia, bleeding and/or bruising. […] Each year in Australia around 330 people are diagnosed with CML. Overall, CML is a rare disease, accounting for around 0.03% of all cancers diagnosed. […] CML can occur at any age but it is more common in adults over the age of 40, who account for nearly 70% of all cases. CML occurs more frequently in men than women and is rarely diagnosed in children.

The establishment of regional development poles in the State of Pernambuco, Brazil was characterized by industrial expansion and consequent concerns about the increase in the occurrence of diseases, specifically those having long latency periods, as is the case of Chronic Myeloid Leukemia. […] A total incidence of 3.4 cases per 100,000 inhabitants was found, with a predominance of the disease among males, a median age of 47 years, a mestizo ethnicity, with elementary schooling and residence in urban area. […] The present study determined the incidence and characterized the spatial distribution of Chronic Myeloid Leukemia cases over a decade in a northeastern Brazilian state. The variation in the incidence rate by region of development is compatible with a homogeneous distribution of the cases.

Chronic myeloid leukemia (CML) is a rare clonal myeloproliferative disorder characterized by enhanced proliferative capacity and prolonged survival of hematopoietic stem cells. The pathogenesis of CML is driven by a bcr-abl fusion oncoprotein formed by a balanced translocation between chromosomes 9 and 22. Prevalence rate of CML has increased by use of tyrosine kinase inhibitors that transformed CML into a chronic disease. […] Reliable epidemiological information on CML in low and middle income countries is limited. Geographic and/or ethnic variation might contribute to the variability of incidence among registries. […] A total of 801 cases entered this study, which corresponds to an annual incidence of 0.79 /105 inhabitants. Mean age at diagnosis was 47 years, 16% of patients had more than 65 years, 5% of patients had less than 20 years. CML was slightly more frequent in males than in females (sex ratio 1.1). More than 85% of the patients were in chronic phase when diagnosed.

National and regional population-based registries are, provided diagnostic accuracy and full coverage of the target population, indispensible tools for epidemiological research. Chronic myeloid leukaemia (CML) registries with more comprehensive reporting may also provide complementary data on treatment outcome to those obtained from clinical trials. Reports from several European CML registries consistently show a crude annual incidence of 0.7-1.0/100,000, a median age at diagnosis of 57-60 years and a male/female ratio of 1.2-1.7. The incidence of CML has been stable over time. Worldwide, variations in the reported incidence of CML may be due to methodological issues, but a true difference between different geographical areas and/or ethnical subgroups cannot be excluded. The prevalence of CML is not well known but has been estimated to be 10-12/100,000 inhabitants with a steady increase due to the dramatic improvement in survival of these patients.

Chronic myeloid leukemia (CML; previously called chronic myelogenous leukemia, chronic myelocytic leukemia, or chronic granulocytic leukemia) is a myeloproliferative neoplasm that manifests uncontrolled proliferation of mature and maturing granulocytes in blood and bone marrow. CML accounts for approximately 15 percent of adult leukemias. The median age at diagnosis is in the sixties, but CML can occur at any age. Most patients present with chronic phase (CP) CML, which is a relatively indolent disorder of excessive mature and maturing neutrophils, basophils, and eosinophils, with or without splenomegaly and/or constitutional symptoms. Up to one-half of patients with CP CML are asymptomatic at diagnosis. In regions with limited access to medical care, patients often present with more advanced disease.

CML usually presents at a median age of 60 years in Caucasians, but at younger age (35â45 years) in Asians. It is rare in children contributing only 2â3% of all pediatric leukemia cases. The global incidence rate of CML is 15/1,000,000 per year with a male to female ratio of 1.34 while the age-adjusted incidence rate for the age group <18 years is 1.0 per 1,000,000. In the first three years of life pediatric CML is extremely rare. The SEERS database showing pooled data on all myeloproliferative diseases at childhood age lists a continuously increasing incidence rate from 0.7 cases in the age group 1 to 4 years up to 4.3 cases per 1,000,000 at 15 to 19 years. From the authorsâ experience, myeloproliferative diseases besides CML like essential thrombocytosis, polycythemia vera and myelofibrosis are more than 10-fold less frequent than CML in the first two decades of life. Therefore, the SEERS data give a rather detailed impression on the continuous increase in the incidence of CML especially in the 2nd decade of life.

In a population-based study of chronic myeloid leukemia (CML) patients in Switzerland, we confirmed an increase in relative survival for all age groups over the last decades. This was primarily based on the stable age-adjusted rate of incidence and a substantial decrease of the age-adjusted mortality rate. […] The age-standardized rate (ASR) for the incidence remained stable, while the ASR for mortality decreased by 50â80%, resulting in a five-year RS from 36% to 74% over all four age groups. […] The ASR for mortality of CML patients in the Swiss CCRs impressively decreased for all patients over the complete observation period, from 0.80 for 1995 to 2000 to 0.21 per 100,000 py for 2013 to 2017. […] The considerable improvement of the age-standardized RS in our Swiss cohort of CML patients over the last 20 years is based on the fairly stable incidence and the substantial decrease in mortality. […] Importantly, in delineating the RS for the different age groups and time periods, we found important benefits associated with the changes in CML management for all age groups over the last 20 years.

With a number of new diagnostics at 288 patients older than 20 in Andalusia between 2005 and 2012, accumulated incidence rates as it is adjusted to the European standard population for CML in Andalusia is of 0.97 cases out of every 100.000 inhabitants/year. […] CML incidence in Andalusia is comparable to that described in the scientific literature and is in keeping with results from the European registry EUTOS from 2015. […] Epidemiological characteristics from our patients are homogeneous to those described in other registries in terms of sex, age of diagnosis and prognostication indices distribution. […] The creation of RALMC on population basis allows to obtain information regarding CML in real life, which is in turn needed for health planning and resource management in clinical praxis and support outside of clinical trials. However, methodological limitations in our registry must be taken into consideration: in Spain, CML patients are not obliged to declare their status, participation in RALMC is voluntary and inclusion is done under written consent.

In the era of tyrosine kinase inhibitor (TKI) treatment, the progression of chronic myeloid leukemia (CML) remains a significant clinical challenge, and genetic biomarkers for the early identification of CML patients at risk for progression are limited. This study explored whether essential circular RNAs (circRNAs) can be used as biomarkers for diagnosing and monitoring CML disease progression and assessing CML prognosis. […] The aberrant expression of hsa_circ_0006010 and hsa_circ_0002903 during CML progression could serve as valuable biomarkers for differentiating CML-AP/BP patients from CMP-CP patients or HCs. […] Furthermore, survival analysis revealed that high hsa_circ_0006010 expression and low hsa_circ_0002903 expression indicated poor progression-free survival (PFS) in CML patients.

Chronic myeloid leukemia (CML; previously called chronic myelogenous leukemia, chronic myelocytic leukemia, or chronic granulocytic leukemia) is a myeloproliferative neoplasm that manifests uncontrolled proliferation of mature and maturing granulocytes in blood and bone marrow. CML accounts for approximately 15 percent of adult leukemias. The median age at diagnosis is in the sixties, but CML can occur at any age. Most patients present with chronic phase (CP) CML, which is a relatively indolent disorder of excessive mature and maturing neutrophils, basophils, and eosinophils, with or without splenomegaly and/or constitutional symptoms. Up to one-half of patients with CP CML are asymptomatic at diagnosis. In regions with limited access to medical care, patients often present with more advanced disease.

Chronic myeloid leukemia (CML) is a type of blood cancer that affects hematopoietic stem cells and is often characterized by the presence of the Philadelphia chromosome. […] The median age of people affected is approximately 56 years and it accounts for about 15-20% of leukemia in adults. CML incidence worldwide varies from 0.6 to 2.8/100,000 individuals per year. […] The WHOs recent definition of CML stages divides disease progression into two phases: An accelerated phase (AP) with continuous or increasing splenomegaly, persistent or increasing leukocytosis. […] Cytogenetic and molecular biology techniques play a key role in the detection of chromosomal abnormalities and mutations involved in the oncogenesis of the disease. […] As for the treatment of CML, advances in science have led to the introduction of tyrosine kinase inhibitors, as a targeted therapy, which acts directly on the kinase activity of the BCR-ABL oncoprotein.

The cytogenetic response is a decrease in the percentage of Ph+ cells evaluated by analysis of residual metaphases according to conventional or molecular cytogenetics. […] TKI resistance is defined as a patient’s non-response after treatment. […] The management of chronic myeloid leukemia with Ph+ has undergone significant progress over a relatively short period, starting with allogeneic hematopoietic stem cell transplantation and recombinant interferon alfa (rIFN) or drugs used as initial treatment such as Hydroxyurea, Cytarabine or Busulfan, and more recently tyrosine kinase inhibitors (TKIs). […] In general, chronic myeloid leukemia has become manageable and curable over the decades thanks to advances in cancer therapy.

With a number of new diagnostics at 288 patients older than 20 in Andalusia between 2005 and 2012, accumulated incidence rates as it is adjusted to the European standard population for CML in Andalusia is of 0.97 cases out of every 100.000 inhabitants/year. […] CML incidence in Andalusia is comparable to that described in the scientific literature and is in keeping with results from the European registry EUTOS from 2015. […] Epidemiological characteristics from our patients are homogeneous to those described in other registries in terms of sex, age of diagnosis and prognostication indices distribution. […] The creation of RALMC on population basis allows to obtain information regarding CML in real life, which is in turn needed for health planning and resource management in clinical praxis and support outside of clinical trials. However, methodological limitations in our registry must be taken into consideration: in Spain, CML patients are not obliged to declare their status, participation in RALMC is voluntary and inclusion is done under written consent.

The epidemiology of CML in low and middle income countries is limited. Differences in age at diagnosis and overall survival exist between regions. Epidemiological studies should be conducted to assess for possible environmental factors associated with clinical and outcome characteristics. […] Between January 2011 and December 2019, a total of 801 newly diagnosed patients with CML (415 men and 376 women) were registered in Tunisia. This corresponds to an annual incidence of 7.9 per 106 inhabitants. The diagnosis of CML was confirmed by karyotyping and/or RT-PCR in all cases. Median age at diagnosis was 49 years, 16% of patients had more than 65 years and 5% were less than 20 years. […] Chronic myeloid leukemia accounts for 15% of adult leukemias, an increasing annual prevalence rate of CML is observed in Tunisia and all over the world, this is due to the use of TKI therapy positively influencing survival and life expectancy of CML patients.

National and regional population-based registries are, provided diagnostic accuracy and full coverage of the target population, indispensible tools for epidemiological research. Chronic myeloid leukaemia (CML) registries with more comprehensive reporting may also provide complementary data on treatment outcome to those obtained from clinical trials. Reports from several European CML registries consistently show a crude annual incidence of 0.7-1.0/100,000, a median age at diagnosis of 57-60 years and a male/female ratio of 1.2-1.7. The incidence of CML has been stable over time. Worldwide, variations in the reported incidence of CML may be due to methodological issues, but a true difference between different geographical areas and/or ethnical subgroups cannot be excluded. The prevalence of CML is not well known but has been estimated to be 10-12/100,000 inhabitants with a steady increase due to the dramatic improvement in survival of these patients.

Chronic myeloid leukemia (CML) is being studied in labs and in clinical trials around the world. […] Researchers are looking closely at how specific gene changes could be used to determine treatment, predict disease progression, and develop other drugs to treat CML. […] Because TKIs have drastically changed the treatment and outcomes of CML, an exciting area of research is looking at whether TKI treatment can be stopped. Clinical trials are being done to see if this is possible and what should be done if the CML comes back. […] Scientists continue to look for new drugs to treat CML, especially CML that no longer responds to TKIs. […] Several vaccines are now being studied for use against CML, but more research is needed.

National and regional population-based registries are, provided diagnostic accuracy and full coverage of the target population, indispensable tools for epidemiological research. […] Reports from several European CML registries consistently show a crude annual incidence of 0.71.3/100,000, median age at diagnosis of 5660 years and a male/female ratio of 1.21.7. […] The incidence of CML has been stable over time. […] The prevalence of CML is less well known but has been estimated to 1520/100,000 inhabitants with a steady increase due to the profound improvement in survival of these patients. […] The impact of socioeconomic factors and health-care settings related to long-term outcome, a possible increased risk of secondary cancer development and identification of adverse off-target effects related to the continuous administration of tyrosine kinase inhibitors are among areas of ongoing epidemiological research in CML.

The finding of regional differences in age at diagnosis demonstrates that there exists a possible environmental factor that may be impacting the pattern of CML. […] CML prevalence is anticipated to increase due to therapeutic advancements, continuous evaluation of adherence to CML guidelines and treatment results is of key importance. […] Many important differences in hematological cancers, including CML, have been highlighted in various publications in developing countries vs developed countries. These include differences in incidence and prevalence rates, age, and stage of disease at diagnosis, response rates, and survival.

The survival gap was seen among patients above 50 years of age, whereas the OS of younger patients corresponded to the OS of the general population. […] The current study demonstrated a continued increase in age-standardized 5-year OS during an extended period from 1995-2017. […] Despite a remarkable improvement in 5-year OS among patients with CML during the TKI era, the survival has not yet matched that of the general population. […] The findings of the study provide optimism for patients with CML, as they can expect survival rates approaching those of the general population.
