Leukemia is a cancer of the blood or bone marrow characterized by an abnormal increase of immature white blood cells. There are several types classified by how quickly the disease develops (acute or chronic) and the affected blood cell type (lymphoid or myeloid). Common types include acute lymphoblastic leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, and chronic myeloid leukemia. Treatment involves chemotherapy, radiation therapy, or stem cell transplantation and varies depending on the leukemia type and stage.

Definition
Leukemia is atype of cancer of the blood or bone
marrow characterized by an abnormal increase of
immature white blood cells called "blasts".
Leukemia is a broad term covering a spectrum of
diseases. In turn, it is part of the even broader group
of diseases affecting the blood, bone marrow, and
lymphoid system, which are all known as tumors of
the hematopoietic and lymphoid tissues.
Leukemia is a treatable disease. Most treatments
involve chemotherapy, medical radiation therapy, or
hormone treatments.
3.
Classification
There are severaltypes of leukemia. The different types
of leukemia are grouped in two ways. One way is by how
quickly the disease develops and gets worse. The other
way is by the type of blood cell that is affected.
By how quickly the disease develops
• Chronic
• Acute
By the type of blood cell that is affected
• Lymphoid cells
• Myeloid cells
4.
Types
I. Acute lymphoblasticleukemia (ALL)
II. Acute myeloid leukemia (AML)
III.Chronic lymphoblastic leukemia(CLL)
IV.Chronic myeloid leukemia (CML)
Other types
• Hairy cell leukemia (HCL)-
• T-cell prolymphotic leukemia (T-PLL)-
• Larger granular lymphocytic leukemia – T-cell or NK cell
• Adult T-cell leukemia – C/A Human T-lymphotropic virus
(HTLV)
5.
Pre –leukemia
Transient myeloproliferativedisease, also termed
transient leukemia, involves the abnormal proliferation
of clone of non-cancerous megakaryoblasts.
The disease is restricted to individuals with down
syndrome .
Resolves within 3 months or ,in 10 % of cases ,progresses
to acute megakaryoblastic leukemia .
Leukemia V/S Lymphoma
•Malignant cells diffusely
invade the bone marrow
and get spilled into the
peripheral circulation
• Peripheral blood film can
be diagnostic
• Bone marrow is almost
always involved
• Malignant cells form a
soft tissue mass in some
tissues or organs
• Do not spill into
peripheral blood
• Peripheral blood film is
often not diagnostic
• Bone marrow is not
always involved
• Biopsy of the mass is
often needed for
diagnosis
13.
Acute V/S Chronicleukemia
• Leukemia may be acute or chronic
• Acute leukemia are more aggressive and the
patient may die in few months
• Chronic leukemia have more indolent course
of many years
14.
Causes of leukemia
Theaetiology of Leukaemia is not known in most patients. However,
a number of factors have been implicated.
1. Genetic factor:
There is high concordance rate among identical twins if acute leukaemia
develops in the first year of life. Families with excessive incidence of
leukaemia have been identified. Acute leukaemia occur with increased
frequency with a variety of congenital disorder such as Down‟s, Bloom‟s,
Klinefelter‟s and WiskottAldrich‟s syndrome, Fanconi„s anaemia and ataxia
telangiectsia.
2. Environmental factors:
Certain environmental factors are known to play a role in the aetiology of
leukaemia. These include the following;
a. Ionising radiation-e.g.-in individuals exposed to occupational radiation
exposure, patients receiving radiation therapy, and Japanese survivors of
the atomic bomb explosions. Radiation exposure is related to the
development of CML, AML and all but not to CLL or HCL.
b. Chemical carcinogens-e.g. Benzene and other aromatic hydrocarbons
are associated with the development of AML.
15.
3. Infection- Inductionof Leukaemia‟s in experimental animals by RNA viruses
(retro viruses) has been studied for quite some time but more recently viral
aetiology of adult T-cells Leukaemia –Lymphoma (ATLL) by a human retro virus
called human T cells leukaemia –lymphoma virus I (HTLV-I) and (HTLV-II) for T
cells variant of hairy cells leukaemia has been established
4. Cigarette, cigar, and pipe smoking have been associated with cancers of the
lung, mouth, bladder, colon, kidney, throat, nasal cavity, voice box,
oesophagus, lip, stomach, cervix, liver, and pancreas, and with leukemia
17.
Acute leukemia
• Increasedproliferation of immature cells
(blast cells)
• Only proliferation but no maturation or
differentiation
• Functionless blast cells accumulate in bone
marrow and finally spills into the peripheral
circulation
• No space for normal cells in bone marrow
• Decreased normal functional cells
18.
Acute lymphocytic leukemia
ALLis the most common type of leukemia in young
children. It also affects adults, especially those 65 and
older.
Subtypes include precursor B acute
lymphoblastic leukemia, precursor T acute
lymphoblastic leukemia, Burkitt's leukemia,
and acute biphenotypic leukemia.
While most cases of ALL occur in children, 80% of
deaths from ALL occur in adults
19.
Treatment of ALL
Managementof ALL is directed towards control of bone marrow and systemic
(whole-body) disease. Additionally, treatment must prevent leukemic cells from
spreading to other sites, particularly the central nervous system (CNS) e.g.
monthly lumbar punctures. In general, ALL treatment is divided into several
phases:
Induction chemotherapy to bring about bone marrow remission. For adults,
standard induction plans include prednisone, vincristine, and
an anthracycline drug; other drug plans may include L-
asparaginase or cyclophosphamide. For children with low-risk ALL, standard
therapy usually consists of three drugs (prednisone, L-asparaginase, and
vincristine) for the first month of treatment.
Consolidation therapy or intensification therapy to eliminate any remaining
leukemia cells. There are many different approaches to consolidation, but it is
typically a high-dose, multi-drug treatment that is undertaken for a few months.
People with low- to average-risk ALL receive therapy with antimetabolite drugs
such as methotrexateand 6-mercaptopurine (6-MP). People who are high-risk
receive higher drug doses of these drugs, plus additional drugs.
]
20.
CNS prophylaxis (preventivetherapy) to stop the cancer from
spreading to the brain and nervous system in high-risk people.
Standard prophylaxis may include radiation of the head and/or
drugs delivered directly into the spine.
Maintenance treatments with chemotherapeutic drugs to prevent
disease recurrence once remission has been achieved.
Maintenance therapy usually involves lower drug doses, and may
continue for up to three years.
Alternatively, allogeneic bone marrow transplantation may be
appropriate for high-risk or relapsed people.
21.
Acute myeloid leukemia
(AML)occurs far more commonly in adults than in children, and
more commonly in men than women. It is treated with
chemotherapy. The five-year survival rate is 20%.
One subtype is APL (Acute Promyelocytic Leukemia), which has a
survival rate greater than 90%. Subtypes of AML include acute
promyelocytic leukemia, acute myeloblastic leukemia, and acute
megakaryoblastic leukemia.
22.
Treatment of AML
Manydifferent anti-cancer drugs are effective for the treatment of
AML. Treatments vary somewhat according to the age of the person
and according to the specific subtype of AML. Overall, the strategy is
to control bone marrow and systemic (whole-body) disease, while
offering specific treatment for the central nervous system (CNS), if
involved.
In general, most oncologists rely on combinations of drugs for the
initial, induction phase of chemotherapy. Such combination
chemotherapy usually offers the benefits of early remission and a
lower risk of disease resistance.
Consolidation and maintenance treatments are intended to prevent
disease recurrence. Consolidation treatment often entails a repetition
of induction chemotherapy or the intensification chemotherapy with
additional drugs. By contrast, maintenance treatment involves drug
doses that are lower than those administered during the induction
phase
Chronic Myeloid Leukemia
•Clonal Myeloproliferative disorder
• Incidence is 1.5 per 100,000 people per year
• Constitute about 20% of all leukemia
• Male > Female
• Increases slowly with age until the middle
forties, when it starts to rise rapidly
• The median age of diagnosis is 45 to 55 years
• No etiologic agent is incriminated in CML
26.
Chronic Myeloid Leukemia
•CML is a/w Philadelphia
chromosome
• The Ph chromosome is an
abnormal chromosome
22, resulting from a
reciprocal translocation
between part of the long
arm of chromosome 22
and chromosome 9.
• The resulting karyotype is
described as
t(9;22)(q34;q11)
27.
Chronic Myeloid Leukemia
•This translocation
results in fusion of
Break point cluster
region (BCR) gene of
Chr 22 with Abelson
1(Abl) gene of Chr 9
resulting in Ongogenic
BCR-Abl fusion gene
located in Ph
chromosome
28.
Chronic Myeloid Leukemia
•The new BCR-Abl fusion gene is capable of
being expressed as a messenger RNA &
encodes the Bcr-abl fusion protein.
• The translated p210 protein has tyrosine
kinase activity and enhanced phosphorylating
activity compared with the normal protein
resulting in altered cell growth, stromal
attachment and apoptosis ultimately leading
to CML
29.
Clinical Presentations
• CMLcan present as one of the three phases
– Chronic Phase
– Accelerated Phase
– Blast Crisis
30.
Clinical Presentations
• Asymptomaticto severely symptomatic
• Symptoms due to splenic enlargement
– Early satiety and left upper quadrant pain or mass
• Symptoms due to hypermetabolic state
– fatigue, malaise, weight loss, night sweats
• Symptoms due to leukostatic manifestations due to
severe leucocytosis
– CVA, MI, venous thrombosis, priapism, visual disturbances,
pulmonary insufficiency
• Less common are features related to granulocyte or
platelet dysfunction
– infections, thrombosis, or bleeding.
31.
Clinical Presentations
• Physicalfindings
– Also depends upon the phase of CML
– Mild anemia to severe anemia
– Splenomegaly
– Hepatomegaly
– Lymphadenopathy unsual but can be present at
late stages (blast crisis)
– Bleeding disorders and Infections are rare unless
in blast crisis
32.
Chronic Phase
• Majorityof CML are diagnosed in chronic phase
• Defined by
– Elevated WBC >50,000 (10,000-5,00,000) with left
shift extending to blasts
– Blasts <10% in peripheral blood or bone marrow
– Thrombocytosis and increased Basophils, Eosinophils
– Mild normocytic normocromic anemia
– Low leucocyte alkaline phosphatase score
• Median duration is 4-5 years
33.
Accelerated Phase
• Secondand intermediate phase
• Defined by
– 10-20% blast cells blood or marrow
– basophils ≥20%, platelet count <100,000
– Progressive anemia
– General worsening of the symptoms
• Median duration is 3-18months
34.
Blast Crisis
• Finalphase of the disease
• Transformation into Acute leukemia with
blasts ≥ 20% (Myeloid 70% and lymphoid 30%)
• Increased symptomatology
– Fatigue due to severe anemia
– Bleeding, infections
– Lymphadenopathy
– CNS involvement
• Rapidly fatal
35.
• Diagnosis ofCML is not difficult
– Leucocytosis with left shifting extending to blasts
– Splenomegaly
– Presence of Philadelphia chromosome (90-95%) or
BCR-Abl mRNA in bone marrow sample or blood
36.
Treatment of CML
•Treatment of chronic phase
– Tyrosine kinase inhibitors
– Allogenic stem cell transplantation
– Interferon alpha based treatment
– Chemotherapy to reduce WBC counts with
hydroxyurea or busulphan
37.
• Tyrosine kinaseinhibitors
– Imatinib ( 1st gen), Dasatinib, Nilotinib (newer gen)
– First-line therapy in chronic-phase CML
– Inhibit BCR-ABL tyrosine kinase activity and reduce the
uncontrolled proliferation of WBC
– Complete cytogenetic response is seen in 76% at 18
months of therapy
– Therapy is continued for life in those with complete
cytogenetic response
– Patients are monitored by repeated bone marrow
examination at 6, 12 and 18 months for complete
cytogenetic response then 3-monthly real-time
quantitative polymerase chain reaction (PCR) for BCR ABL
mRNA transcripts in blood.
38.
• Tyrosine kinaseinhibitors
– Those who don’t obtain complete cytogenetic
response at 18 months of treatment are labeled as
treatment failure with imatinib
– These pts are treated with either newer
generation TKIs (desatinib, nilotinib) or allogenic
stem cell transplantation
39.
• Allogenic stemcell transplantation
– Reserved for treatment failure patients with
imatinib
• Interferon alpha with cytarabine, hydroxyurea
or busulphan are being obsolete
• `3
40.
Treatment of CML
•Treatment of accelerated phase
– Imatinib is indicated if the patient has not already
received it but the response is poor
– Hydroxyurea can be used as palliative therapy
41.
Treatment of CML
•Treatment of blast crisis
– Type of blast should be determined and treated as
acute leukemia
– Lymphoblastic transformation is better treated
than myeloblastic
– Supportive management should be considered in
very old pts with myeloid transformation due to
very poor response to treatment
CLL
• Most commontype of leukemia
• Male to female ratio is 2 : 1
• Median age at presentation is 65–70 years
• It results from the clonal expansion of small
lymphocytes and is almost invariably (95%) B cell in
origin
• B lymphocytes fail to transform to plasma cells or
produce antibodies
• An ever-increasing mass of immuno-incompetent cells
accumulates resulting in decrease immunity and bone
marrow failure
44.
Clinical features ofCLL
• The onset is usually insidious.
• In most cases the diagnosis is made incidentally
on a routine CBC.
• In the late stages the patient may present with
features of
– Bone marrow failure,
– Anemia due to autoimmune hemolysis,
– Increased susceptibility to infection,
– Painless lymphadenopathy and
– Systemic symptoms like night sweats and weight loss.
45.
Investigations
• CBC
– WBCis increased with lymphocytosis ( > 5 X 109/L is
criteria for diagnosis)
– RBC may be normal or decreased
– Plts may be normal or decreased
• Peripheral blood smear
– Small or medium sized mature and normal appearing
lymphocytes.
– Smudge cells may be seen
– No immature blasts are evident.
46.
Investigations
• Immunophenotyping
– MonoclonalB cells expressing the B cell antigens
CD19 and CD23, with either kappa or lambda
immunoglobulin light chains
• Serum immunoglobulin
– levels should be estimated to establish the degree
of immunosuppression
47.
Investigations
• Bone marrowexamination
– Not essential for the diagnosis of CLL
– For prognosis (patients with diffuse marrow
involvement have a poor prognosis)
– Monitoring treatment
• Other
– Retics
– Direct Coomb’s test
Treatment
• Treatment isonly required if
– there is evidence of bone marrow failure
– massive or progressive lymphadenopathy or
splenomegaly
– systemic symptoms such as weight loss or night
sweats
– rapidly increasing lymphocyte count
– autoimmune haemolytic anaemia
– thrombocytopenia
50.
Treatment
• Stage ACLL
– No treatment is needed apart from the proper
counselling about the disease
51.
Treatment
• Stage Band C CLL
– Oral chemotherapy with chlorambucil
– Purine analogue fludarabine in combination with
cyclophosphamide
– Anti-CD20 monoclonal antibody rituximab
– Corticosteroids for autoimmune cytopenias
52.
Treatment
• Supportive treatment
–Transfusions of blood for symptomatic anaemia or
thrombocytopenia
– prompt treatment of infections or
immunoglobulin replacement.
– Radiotherapy for lymphadenopathy which is
causing discomfort or local obstruction
– Splenectomy
53.
Prognosis
• The successof treatment depends on the type of leukemia and the age of
the person. Outcomes have improved in the developed world.
• The average five-year survival rate is 61% in the United States. In children
under 15, the five-year survival rate is greater (60 to 85%), depending on
the type of leukemia. In children with acute leukemia who are cancer-free
after five years, the cancer is unlikely to return.
• Outcomes depend on whether it is acute or chronic, the specific abnormal
white blood cell type, the presence and severity
of anemia or thrombocytopenia, the degree of tissue abnormality, the
presence of metastasis and lymph node and bone marrow infiltration, the
availability of therapies and the skills of the health care team.
• Treatment outcomes may be better when people are treated at larger
centers with greater experience
Raktarbud
According to vagbhat,Vitiated Dosha will constricted and compress the blood
within the Venous (siras). This will be mature it before time hence obstruction of
bleeded blood produce lump of mamsa covered with muscular sprouts and grow
very fast along with bleedings. This vitiated Shonit (blood) along with circulating
blood within vessels produced Blood cancer. This make the patients suffer from
pandu (Anaemia) and complication of blood
Cancer originates due to a metabolic crisis, i.e. aggravation of vata forces and
suppression of kapha forces, both interacting with one another resulting in
proliferation. However, the abnormal cancerous growth at a specific organ
(Ekadesavriddhi) is managed by compensation from other parts of the body
(Anyasthaniyakshaya), e.g. body weight loss (cachexia) .
Sushruta has proposed six stages in the pathogenesis of all diseases but his
concept suits more to the pathology of the tumour than pathogenesis itself.
56.
Stages of tumouraccording to Ayurveda
1. Sanchaya: early stages of localized neoplastic changes.
2. Prakopa: transformation of primary growths into metastatic tumours.
3. Prasara: metastasis.
4. Sthana samsraya: complete metastasis and secondary growth.
5. Vyakti: clinical signs and symptoms are expressed.
6. Bheda: the stage where differentiation of growth occurs on the basis of
histopathology
57.
Treatment modalities inRaktarbud
During the 7th century BC, Atreya and Dhanwantari used ayuveda medicines for
treating the early stages of cancer and surgery in advanced cases.
In the 8th century AD, Vagbhata, a Buddhist physician composed two texts:
Astanga Hrdaya and Astanga sangraha where new methods for cancer treatment
were introduced.
Other Ayurvedic texts of internal medicine, viz., Chakradatta composed by
Chakrapani (10th century AD), the Sarangadhara Samhita by Sarangadhara (14th
century AD), the Bhavaprakasha Samhita by Bhavamisra (15th century AD), the
Satmya Darpan Samhita by Viswanath (16th century AD), the Vaisajya Ratnabali
by Binoda Lala Sen Gupta (18th Century AD), the Rasatarangini by Sadananda
Sharma (19th century AD), etc. explain numerous remedies to treat internal and
external neoplasms.
58.
Treatment modalities
Though thereis no basic line of treatment of Leukaemia has found in Ayurveda, as
it is Asadhya (incurable), but principle of treatment is as follows :
• Sodhana chikitsha
• Saman chikitsha
• Rasayan chikitsha
• Dhatwagni chikitsha
• Vyadhipratyanika chikitsa (specific anti-cancerous drugs)
• Lakshanika chikitsa (symptomatic treatment)
59.
