Białaczka
Diagnostyka i diagnoza

Diagnostyka białaczek opiera się na wieloetapowym procesie, rozpoczynającym się od morfologii krwi obwodowej (CBC), gdzie obserwuje się m.in. podwyższony poziom leukocytów, obniżone erytrocyty i trombocyty oraz obecność komórek blastycznych. Kluczowym badaniem potwierdzającym rozpoznanie jest biopsja i aspiracja szpiku kostnego, umożliwiająca ocenę odsetka blastów (≥20% w AML i ALL u dorosłych, ≥25% limfoblastów u dzieci w ALL), typowanie komórek oraz przeprowadzenie badań cytogenetycznych i molekularnych. Immunofenotypowanie, głównie cytometria przepływowa, pozwala na precyzyjne określenie podtypu białaczki (np. B-ALL vs T-ALL) oraz monitorowanie minimalnej choroby resztkowej (MRD). Diagnostyka molekularna i cytogenetyczna, w tym analiza kariotypu, FISH, PCR i NGS, identyfikuje charakterystyczne aberracje genetyczne, takie jak chromosom Filadelfia (t(9;22)) w CML czy translokacja t(15;17) w APL, które mają kluczowe znaczenie rokownicze i terapeutyczne.

Diagnostyka Białaczki

Białaczka (leukemia) to złożona grupa nowotworów krwi, których właściwa diagnostyka ma kluczowe znaczenie dla skutecznego leczenia. Dokładna i precyzyjna diagnoza umożliwia określenie konkretnego typu i podtypu białaczki, co jest niezbędne do opracowania optymalnego planu terapeutycznego. Proces diagnostyczny obejmuje szereg specjalistycznych badań, które pozwalają na kompleksową ocenę stanu pacjenta i charakterystykę choroby.12

Badania krwi w diagnostyce białaczki

Punktem wyjścia w procesie diagnostycznym jest zazwyczaj morfologia krwi obwodowej (CBC – Complete Blood Count). Badanie to ocenia liczbę, proporcje i jakość poszczególnych składników krwi. W przypadku białaczki można zaobserwować:123

W przypadku niektórych typów białaczki przewlekłej, sama morfologia krwi oraz ocena mikroskopowa rozmazu krwi obwodowej może być wystarczająca do postawienia wstępnej diagnozy. Jednak w większości przypadków konieczne są dalsze badania diagnostyczne.67

Badanie szpiku kostnego

Podstawowym badaniem potwierdzającym rozpoznanie białaczki jest biopsja i aspiracja szpiku kostnego. Procedura ta polega na pobraniu próbki płynnego szpiku kostnego (aspiracja) oraz fragmentu tkanki kostnej zawierającej szpik (biopsja) najczęściej z kości biodrowej pacjenta.123

Badanie szpiku kostnego umożliwia:45

  • Ocenę odsetka komórek blastycznych w szpiku – kryterium diagnostyczne różnych typów białaczek
  • Określenie typu komórek nowotworowych
  • Przeprowadzenie badań cytogenetycznych i molekularnych
  • Ocenę stopnia zajęcia szpiku przez chorobę

Zgodnie z kryteriami Światowej Organizacji Zdrowia (WHO), diagnoza ostrej białaczki szpikowej (AML) wymaga obecności co najmniej 20% blastów w szpiku kostnym lub krwi, z wyjątkiem niektórych podtypów AML z charakterystycznymi zaburzeniami genetycznymi, gdzie obecność specyficznej zmiany genetycznej jest wystarczająca do rozpoznania, niezależnie od odsetka blastów.67

W przypadku ostrej białaczki limfoblastycznej (ALL) u dorosłych diagnoza wymaga obecności co najmniej 20% blastów pochodzenia limfoidalnego, natomiast u dzieci kryteria diagnostyczne określają próg 25% limfoblastów w szpiku kostnym.89

Badania różnicujące typ białaczki

Immunofenotypowanie

Immunofenotypowanie jest kluczowym badaniem w diagnostyce białaczek, które umożliwia określenie typu i podtypu choroby poprzez identyfikację specyficznych markerów na powierzchni komórek nowotworowych. Najczęściej stosowaną metodą immunofenotypowania jest cytometria przepływowa.12

Cytometria przepływowa to zaawansowana technologia wykorzystująca wiązkę lasera do identyfikacji specyficznych typów komórek w badanej próbce. Pozwala ona na:12

  • Rozróżnienie między białaczką szpikową a limfoblastyczną
  • Określenie podtypu ALL (białaczka B-komórkowa lub T-komórkowa)
  • Identyfikację charakterystycznych markerów immunologicznych komórek nowotworowych
  • Monitorowanie choroby resztkowej (MRD) po leczeniu

W przypadku dorosłych pacjentów z ALL, około 75-80% przypadków dotyczy linii B-komórkowej, a 20-25% linii T-komórkowej.3

Badania cytogenetyczne i molekularne

Badania cytogenetyczne i molekularne mają ogromne znaczenie w diagnostyce białaczek, ponieważ pozwalają na identyfikację specyficznych zmian chromosomalnych i genetycznych, które są charakterystyczne dla określonych typów białaczek. Informacje te mają kluczowe znaczenie dla rokowania i wyboru optymalnego leczenia.123

Do najważniejszych badań cytogenetycznych i molekularnych należą:456

  • Analiza kariotypu – badanie całości chromosomów w poszukiwaniu dużych aberracji chromosomowych
  • Fluorescencyjna hybrydyzacja in situ (FISH) – metoda pozwalająca na wykrycie specyficznych zmian w konkretnych genach lub fragmentach chromosomów
  • Reakcja łańcuchowa polimerazy (PCR) – technika molekularna umożliwiająca wykrycie specyficznych mutacji genowych
  • Sekwencjonowanie nowej generacji (NGS) – zaawansowana metoda badania DNA pozwalająca na kompleksową analizę genomu komórek białaczkowych

Przykładowo, w przewlekłej białaczce szpikowej (CML) charakterystyczną zmianą jest obecność chromosomu Filadelfia, powstającego w wyniku translokacji t(9;22). Wykrycie tej zmiany jest kluczowe dla diagnozy CML i ma istotne znaczenie terapeutyczne.12

W przypadku ostrej białaczki promielocytowej (APL), podtypu AML, identyfikacja translokacji t(15;17) jest diagnostyczna i determinuje specyficzne podejście terapeutyczne, odmienne od innych typów AML.34

Dodatkowe badania diagnostyczne

Badanie płynu mózgowo-rdzeniowego

Nakłucie lędźwiowe (punkcja lędźwiowa) wykonuje się w celu oceny, czy białaczka rozprzestrzeniła się do ośrodkowego układu nerwowego. Jest to szczególnie istotne w przypadku ostrej białaczki limfoblastycznej (ALL), która ma tendencję do zajmowania OUN.123

Procedura polega na wprowadzeniu cienkiej igły w przestrzeń podpajęczynówkową w dolnej części kręgosłupa i pobraniu niewielkiej ilości płynu mózgowo-rdzeniowego. Płyn ten jest następnie badany pod kątem obecności komórek białaczkowych.45

Nakłucie lędźwiowe może być również wykorzystywane do podawania chemioterapii dokanałowo w celu leczenia lub zapobiegania zajęciu OUN przez białaczkę.6

Badania obrazowe

Badania obrazowe nie są zazwyczaj podstawowymi metodami diagnostycznymi w białaczce, ale mogą być pomocne w ocenie rozprzestrzeniania się choroby oraz wykrywaniu powikłań. Do najczęściej stosowanych badań obrazowych należą:12

  • RTG klatki piersiowej – może wykazać powiększenie węzłów chłonnych śródpiersia lub infekcje płucne34
  • Tomografia komputerowa (CT) – umożliwia ocenę powiększenia narządów wewnętrznych, takich jak wątroba i śledziona, oraz węzłów chłonnych56
  • Rezonans magnetyczny (MRI) – szczególnie przydatny w ocenie zajęcia ośrodkowego układu nerwowego78
  • Pozytonowa tomografia emisyjna (PET) – może być pomocna w wykrywaniu aktywnych ognisk nowotworowych9
  • USG – nieinwazyjna metoda oceny narządów jamy brzusznej1011

Kryteria diagnostyczne różnych typów białaczki

Ostra białaczka szpikowa (AML)

Rozpoznanie AML opiera się na następujących kryteriach:123

  • Obecność co najmniej 20% blastów szpikowych w szpiku kostnym lub krwi obwodowej
  • Lub obecność charakterystycznych zaburzeń genetycznych, takich jak t(8;21), inv(16), t(16;16) lub PML-RARA, niezależnie od odsetka blastów
  • Potwierdzenie szpikowego pochodzenia blastów (w odróżnieniu od blastów limfoidalnych)

Klasyfikacja AML według WHO uwzględnia 15 różnych podtypów, które różnią się rokowanie i optymalnym podejściem terapeutycznym.45

Ostra białaczka limfoblastyczna (ALL)

Kryteria diagnostyczne ALL obejmują:123

  • U dorosłych: obecność co najmniej 20% limfoblastów w szpiku kostnym
  • U dzieci: obecność co najmniej 25% limfoblastów w szpiku kostnym
  • Potwierdzenie limfoidalnego pochodzenia blastów
  • Klasyfikacja immunofenotypowa na ALL z komórek B (B-ALL) lub ALL z komórek T (T-ALL)

Ważnymi czynnikami prognostycznymi w ALL są zmiany cytogenetyczne, takie jak obecność chromosomu Filadelfia (Ph+), który identyfikuje podtyp wymagający specyficznego leczenia.45

Przewlekła białaczka szpikowa (CML)

Diagnostyka CML opiera się na:12

  • Obecności zwiększonej liczby dojrzewających granulocytów w szpiku kostnym i krwi obwodowej
  • Wykryciu chromosomu Filadelfia (translokacja t(9;22)) i/lub genu fuzyjnego BCR-ABL
  • Określeniu fazy choroby (przewlekła, akceleracji, blastyczna)

Diagnostyka molekularna genu BCR-ABL jest kluczowa nie tylko dla diagnozy, ale również dla monitorowania odpowiedzi na leczenie inhibitorami kinazy tyrozynowej.3

Przewlekła białaczka limfocytowa (CLL)

Kryteria diagnostyczne CLL to:12

  • Obecność ≥5 × 10^9/L monoklonalnych limfocytów B we krwi obwodowej
  • Charakterystyczny immunofenotyp limfocytów białaczkowych (CD19+, CD5+, CD23+)
  • Monoklonalność potwierdzona badaniem cytometrii przepływowej

CLL jest często wykrywana przypadkowo podczas rutynowych badań krwi u pacjentów bezobjawowych.34

Znaczenie precyzyjnej diagnostyki w leczeniu białaczki

Dokładna i kompleksowa diagnostyka białaczki ma kluczowe znaczenie dla określenia optymalnej strategii terapeutycznej.123

Zindywidualizowane podejście terapeutyczne opiera się na:45

  • Dokładnym określeniu typu i podtypu białaczki
  • Identyfikacji specyficznych zmian genetycznych i molekularnych
  • Ocenie stanu pacjenta i współistniejących chorób
  • Wieku pacjenta i ogólnym stanie zdrowia

Na przykład, wykrycie mutacji genetycznych może kwalifikować pacjenta do terapii celowanej, takiej jak inhibitory kinazy tyrozynowej w przypadku CML z obecnością genu BCR-ABL.12

Profilowanie molekularne umożliwia również przewidywanie odpowiedzi na leczenie i monitorowanie choroby resztkowej po terapii.345

Monitorowanie choroby i odpowiedzi na leczenie

Po rozpoznaniu białaczki i wdrożeniu leczenia, konieczne jest regularne monitorowanie odpowiedzi na terapię. Służą do tego:12

  • Badania morfologii krwi – ocena normalizacji parametrów krwi
  • Kontrolne badania szpiku kostnego – ocena remisji cytologicznej (< 5% blastów w szpiku)
  • Badania molekularne (PCR) – wykrywanie minimalnej choroby resztkowej (MRD)
  • Badania cytogenetyczne – monitorowanie remisji cytogenetycznej

Zgodnie z kryteriami odpowiedzi na leczenie w AML, remisja jest definiowana jako:3

  • Prawidłowa morfologia krwi obwodowej
  • Mniej niż 5% blastów w szpiku kostnym
  • Brak objawów białaczki w OUN i innych narządach

Nowoczesne metody diagnostyczne, takie jak PCR czy cytometria przepływowa, pozwalają na wykrycie minimalnej choroby resztkowej na poziomie 1 komórki nowotworowej na 10 000-100 000 komórek prawidłowych, co ma istotne znaczenie prognostyczne.45

Kompleksowe podejście do diagnostyki białaczki

Diagnostyka białaczki wymaga kompleksowego podejścia z wykorzystaniem różnorodnych metod badawczych. Współpraca między klinicystami, hematologami, patologami i specjalistami w dziedzinie diagnostyki molekularnej jest kluczowa dla postawienia precyzyjnej diagnozy.123

Nowoczesne ośrodki hematoonkologiczne dysponują zaawansowanymi narzędziami diagnostycznymi, które umożliwiają:45

  • Szybką i dokładną diagnozę
  • Kompleksową charakterystykę molekularną i genetyczną choroby
  • Indywidualizację podejścia terapeutycznego
  • Precyzyjne monitorowanie odpowiedzi na leczenie

W przypadku podejrzenia białaczki, pacjent powinien zostać skierowany do specjalistycznego ośrodka hematologicznego, gdzie dostępne są zaawansowane metody diagnostyczne, a zespół doświadczonych specjalistów może zapewnić kompleksową opiekę.123

Wczesna i precyzyjna diagnostyka białaczki ma kluczowe znaczenie dla poprawy rokowania pacjentów, umożliwiając wdrożenie optymalnego leczenia dostosowanego do specyficznego typu choroby i charakterystyki indywidualnego pacjenta.12

    Leukemia starts when the DNA of a single cell in your bone marrow changes (mutates) and cant develop and function normally. […] Treatments for leukemia depend on the type of leukemia you have, your age and overall health, and if the leukemia has spread to other organs or tissues. […] Results from routine blood work can alert your healthcare provider that you may have an acute or chronic form of leukemia that requires further testing. Or they may recommend a workup if you have leukemia symptoms. […] Diagnostic exams and tests may include: Physical exam: Your healthcare provider will ask about your symptoms and feel for swollen lymph nodes and an enlarged spleen or liver. […] Complete blood count (CBC): This blood test lets your healthcare provider know if you have abnormal levels of red blood cells, white blood cells and platelets. If you have leukemia, youll likely have higher than normal counts of white blood cells.

    Analysis of blood sample through a complete blood count, microscopic evaluation or flow cytometry. […] The next step may be molecular testing to evaluate the cytogenetics (the cells’ chromosomes). […] Diagnosing leukemia in its earliest stages can improve a patients prognosis, so it is important to be tested as soon as possible if leukemia is suspected. […] A diagnosis of leukemia is usually made by analyzing a patients blood sample through a complete blood count (CBC) or microscopic evaluation of the blood, or by using flow cytometry. […] Flow cytometry is a very sensitive technology that uses a laser beam to identify the very specific types of cells found in a sample. […] Molecular testing evaluates the cytogenetics (the chromosomes within the cell) to look for chromosomal variations or abnormalities in the cells. […] There are some specific cytogenetic abnormalities that are very specific to leukemia, and the presence or absence of these abnormalities can help us decide if a patient should have a particular chemotherapy regimen or possibly a bone marrow transplant.

    Many people with chronic myeloid leukemia (CML) don’t have symptoms when it’s diagnosed. The leukemia is often found when their doctor orders blood tests for an unrelated health problem or during a routine check-up. Even when symptoms are present, they’re often vague and non-specific. […] If signs and symptoms suggest you may have leukemia, the doctor will need to check your blood and bone marrow to be certain of this diagnosis. […] Most people with CML have too many white blood cells with a lot of early (immature) cells called myeloblasts or blasts. […] In people with CML, the bone marrow is often hypercellular because it’s full of leukemia cells. […] Some sort of gene testing will be done to look for the Philadelphia chromosome and/or the BCR-ABL gene. This type of test is used to confirm a CML diagnosis and learn more about your CML cells.

    Bone marrow aspiration and biopsy are procedures that involve collecting cells from the bone marrow. In bone marrow aspiration, a needle is used to draw a sample of the bone marrow fluid. In a bone marrow biopsy, a needle is used to collect a small amount of solid tissue. The samples are typically taken from the hip bone. The samples go to a lab for testing. […] In the lab, tests can look for DNA changes in the bone marrow cells. Which DNA changes are present in your bone marrow cells are an important part of diagnosing AML. The results can help your healthcare team create a treatment plan. […] Sometimes, a lumbar puncture may be needed if there’s concern that the leukemia has spread to the brain and spinal cord. A lumbar puncture also is called a spinal tap. It removes a sample of the fluid that surrounds the brain and spinal cord. A small needle is inserted into the lower back to remove a fluid sample. The sample is sent to a lab.

  • #1 Acute myeloid leukemia – Wikipedia
    https://en.wikipedia.org/wiki/Acute_myeloid_leukemia
    Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production. […] Diagnosis is generally based on bone marrow aspiration and specific blood tests. […] A complete blood count, which is a blood test, is one of the initial steps in the diagnosis of AML. It may reveal both an excess of white blood cells (leukocytosis) or a decrease (leukopenia), and a low red blood cell count (anemia) and low platelets (thrombocytopenia) can also be commonly seen. […] A definitive diagnosis requires a bone marrow aspiration and biopsy. […] Bone marrow is examined under light microscopy, as well as flow cytometry, to diagnose the presence of leukemia, to differentiate AML from other types of leukemia (e.g. acute lymphoblastic leukemia), and to provide information about how mature or immature the affected cells are that can assist in classifying the subtype of disease.

    Diagnosing acute lymphoblastic leukemia (ALL) and your ALL subtype usually involves a series of tests. An accurate diagnosis of the subtype is important. The exact diagnosis helps the doctor […] If the CBC findings suggest leukemia, a diagnosis of ALL can sometimes be confirmed with additional testing of the blood sample. Sometimes, however, an ALL diagnosis can be made only after the examination of a sample of bone marrow cells. […] After your doctor takes samples of your blood and bone marrow, a hematopathologist confirms a diagnosis and identifies the ALL subtype. A hematopathologist is a specialist who studies blood cell diseases by looking at samples of blood and marrow cells and other tissues. […] The diagnosis of ALL is confirmed by identifying: Leukemic blast of lymphoid origin (lymphoblasts) in the bone marrow samples. The percentage of blast cells in the bone marrow. Typically, there are no blast cells in the blood and no more than 5 percent of the cells in the bone marrow are blast cells. In ALL, at least 20 percent of the cells in the bone marrow are lymphoblasts. […] If you’re diagnosed with ALL, blood and bone marrow tests are also done during or after treatment to see how your ALL cells are responding to therapy.

    A routine CBC showing an elevated white blood cell (WBC) count with lymphocytic predominance or a normal WBC count with lymphocytosis on differential is often the first indication of an underlying diagnosis of CLL. […] Flow cytometry demonstrating greater than or equal to 5 109/L clonal B cells is diagnostic of CLL. […] Bone marrow examination should be undertaken in evaluation for CML. Identification of the Ph chromosome on cytogenetic or molecular studies confirms the diagnosis in the 95% of patients with this genetic abnormality.

    Doctors may order imaging exams to look for the presence of cancer in different parts of the body. […] In untreated AML, the disease is newly diagnosed. It has not been treated except to relieve signs and symptoms such as fever, bleeding, or pain, and the following are true: The complete blood count is abnormal. At least 20% of the cells in the bone marrow are blasts (leukemia cells) or there are certain gene changes. There are signs or symptoms of leukemia. […] In AML in remission, the disease has been treated and the following are true: The complete blood count is normal. Less than 5% of the cells in the bone marrow are blasts (leukemia cells). There are no signs or symptoms of leukemia in the brain and spinal cord or elsewhere in the body. […] After treatment with chemotherapy, some patients with newly diagnosed AML will not go into remission. This is called refractory cancer. In contrast, relapsed or recurrent AML is cancer that has recurred (come back) after remission. The AML may come back in the blood and bone marrow or also as leukemia deposits in other tissues (extramedullary disease, i.e. leukemia outside the bone marrow).

    The workup of leukemia is very involved, and multiple tests are needed to confirm a diagnosis and, subsequently, to stage the disease. […] A bone marrow aspiration and biopsy are often required for the diagnosis of acute leukemias. […] For chronic leukemias, peripheral blood evaluation is often enough, and an invasive bone marrow biopsy may not be needed. […] Patients with leukemia should be referred to a hematologist-oncologist to initiate treatment. […] The predominant challenge at the time of diagnosis of acute myeloid leukemia is to identify the possibility of APL, which has a significantly different treatment compared to the rest of AML. […] The overall outcome depends upon the patient’s response to induction therapy and the presence or absence of MRD (minimal residual disease) needing further therapies and BMT. […] The differential diagnosis is broad because leukemia is a broad diagnosis with non-specific symptoms. […] Long-term survival with leukemia varies tremendously based on leukemia subtype, cytogenetic and molecular findings, patient age, and comorbid conditions.

    In a biopsy, suspected cancer cells are retrieved by the care team and studied under a microscope. For leukemia, patients undergo a bone marrow biopsy. This requires taking a sample of bone marrow from the hip with a needle to determine if cancerous cells are present. […] If a patient is diagnosed with leukemia, additional tests can determine whether certain chromosomes or gene mutations are present in the diseased cells, or if they have specific proteins or molecules on their surface. This process, sometimes referred to as molecular profiling, can help doctors determine the patient’s exact type of leukemia and his or her prognosis. […] While leukemia starts in the bone marrow, it may spread to the central nervous system (the brain and spinal cord). This is most common in acute lymphocytic leukemia but can occur in any type of leukemia.

    Acute lymphoblastic leukemia (ALL) is a disseminated malignancy of B- or T-lymphoblasts which imposes a rapid and accurate diagnostic process to support an optimal risk-oriented therapy and thus increase the curability rate. […] Current standards for acute lymphoblastic leukemia (ALL) diagnosis integrate the study of cell morphology, immunophenotype and genetics/cytogenetics as detailed in the 2008 WHO classification of lymphoid neoplasms. […] A morphological bone marrow assessment represents the first step in the diagnostic pathway, for the primary diagnosis of ALL and for the differentiation from acute myeloid leukemia (AML), since ALL, by definition, always presents with bone marrow involvement. […] Immunophenotyping by means of multi-channel flow cytometry (MFC) has become the standard procedure for ALL diagnosis and subclassification, and was also developed as useful tool for the detection and monitoring of minimal residual disease (MRD).

    Leukemia Diagnosis […] Our doctors perform a variety of tests to diagnose leukemia and determine its type and subtype. These tests can reveal abnormalities in the appearance of cells and the amounts of different types of blood cells in circulation, changes in the bone marrow, or specific alterations in the genetic and molecular makeup of the diseased cells. […] Tests we may recommend include: cytogenetic studies to look for chromosomal changes in cells, immunohistochemistry studies, in which antibodies are used to distinguish between types of cancer cells, flow cytometry, which involves passing cells through a laser beam for analysis, molecular genetic studies, which are highly sensitive DNA and RNA tests to determine specific genetic traits of cancer cells. […] In order to do these tests, physicians need to collect blood and tissue samples. There are several procedures that allow them to obtain these samples.

    Finding a Ph chromosome is helpful in diagnosing CML. […] PCR can be used to help diagnose CML. It’s also useful after treatment to see if copies of the BCR-ABL gene are still there. If copies of this gene are found it means that the leukemia is still present, even when the cells can’t be seen with a microscope. […] Imaging tests are used to get pictures of the inside of your body. They aren’t needed to diagnose CML, but are sometimes used to look for the cause of symptoms or to see if the spleen or liver are enlarged.

    In rare situations where it’s thought there’s a risk that AML has spread to your nervous system, a lumbar puncture may be carried out. In this procedure, a needle is used to extract a sample of the fluid that surrounds and protects your spine (cerebrospinal fluid) so it can be checked for cancerous cells. If cancerous cells are found in your nervous system, it may affect your treatment.

    Most cancers and leukaemias develop because of gene changes on a particular cell. Genomic testing looks for these changes. […] The results help doctors diagnose the subtype of AML, guide treatment and monitor the response to therapy. […] A PCR test may also be used to check how well treatment has worked. […] Chromosome 22 is abnormal in about 1 in 4 adults with ALL. This is known as the Philadelphia chromosome. […] BCR-ABL is considered a cancer gene because it is present only in developing leukaemia cells.

    The workup of leukemia is very involved, and multiple tests are needed to confirm a diagnosis and, subsequently, to stage the disease. […] A bone marrow aspiration and biopsy are often required for the diagnosis of acute leukemias. […] For chronic leukemias, peripheral blood evaluation is often enough, and an invasive bone marrow biopsy may not be needed. […] Patients with leukemia should be referred to a hematologist-oncologist to initiate treatment. […] The predominant challenge at the time of diagnosis of acute myeloid leukemia is to identify the possibility of APL, which has a significantly different treatment compared to the rest of AML. […] The overall outcome depends upon the patient’s response to induction therapy and the presence or absence of MRD (minimal residual disease) needing further therapies and BMT. […] The differential diagnosis is broad because leukemia is a broad diagnosis with non-specific symptoms.
