Introduction
Cancer can occur in any part of the body and results in cells growing at an abnormal rate,
outnumbering the normal cells of the body. The abnormal growth of the cells can give rise to
solid tumors.
Cancer is one of the most prominent causes of death. Tobacco is responsible for the
majority of lung cancer deaths worldwide (Warren & Cummings, 2013). Cancer may be caused
by genetic factors or external mutagenic agents.
This purpose of the report is to describe the causes, symptoms, diagnosis, treatment and
prevention strategies for a type of cancer called Acute Lymphocytic Leukemia (ALL).
Acute Lymphocytic Leukemia
Acute Lymphocytic Leukemia (ALL) is also called Acute Lymphoblastic Leukemia.
Acute means that the cancer spreads very quickly and is fatal. It is called lymphocytic meaning
that it develops from immature forms of white blood cells called lymphocytes. This cancer
occurs as a result of excessive production of immature cancerous white blood cells. It inhibits the
formation of normal cells in the bone marrow thereby causing death (Harrison & Johansson,
2015). The leukemia cells invade the bloodstream and spread to other body parts like the lymph
nodes, central nervous system, spleen, liver and testicles.
Symptoms, diagnosis, staging, and prognosis
Symptoms
The symptoms associated with ALL, include fatigue, fever, shortness of breath, persistent
infections, nose and gum bleeding, weight loss, loss of appetite, night sweats, bone and joint

pain. Enlargement of liver and spleen and enlargement of lymph nodes present in the underarms,
neck and groin can result in the formation of lumps or swelling (Www.cancer.org, 2017).
Diagnosis
Determination of the morphologies of the lymphoblasts by microscopy and
immunophenotypic determination by flow cytometry are some of the essentials required for
correctly diagnosing ALL. Chromosomal analysis is an important tool for diagnosis. Moreover,
RT-PCR, multiplex ligation dependent amplification of probes, FISH and flow cytometry helps
to identify translocations, cellular DNA content and chromosomal abnormalities, respectively
(Inaba, Greaves & Mullighan, 2013).
Staging
The leukemia staging involves accumulation of leukemia cells in the spleen or liver and
by counting blood cells. The stages of ALL include: B cell and T cell staging. The B cell ALL
stages include Early pre-B ALL, common ALL, Pre-B ALL and Mature B cell ALL or Burkitt
leukemia. The T cell ALL stages include Pre-T ALL and mature T-cell ALL
(Www.cancercenter.com, 2017).
Prognosis
Certain factors help in the prognosis of ALL. These include: age (younger patients show
better prognosis), initial count of white blood cells, ALL subtypes (patients with T cell ALL
have better chances of prognosis than individuals with Burkitt leukemia or B cell ALL),
chromosome translocations (individuals with Philadelphia chromosome specific ALL suffer
from poor prognosis), good response to chemotherapy, among others (Schultz et al., 2014). The

IKZF1 gene that encodes transcription factors are altered in 15% of B ALL cases (Inaba, Greaves
& Mullighan, 2013).
Treatments
Treatment is carried out in 3 phases. These are induction, consolidation and maintenance.
Induction helps in remission. Different chemo drug combinations are used like Vincristine,
Prednisone or Dexamethasone and Doxorubicin. Other drugs include Cyclophosphamide, L-
asparaginase, methotrexate, among others. Patients with Philadelphia chromosomes are given
Imatinib. After remission, the next phase called consolidation involves a short chemotherapy
course with the same drugs but in high doses. Following consolidation, patients are subjected to
maintenance chemotherapy, which includes the use of drugs like 6-mercaptopurine or
methotrexate. In some cases, other drugs like prednisone or vincristine are used in combinations
(Pui et al., 2015). Other alternative treatments include stem cell transplantation, radiation
therapy, T cell therapy, acupuncture, insulin potentiation therapy, infusion with high vitamin C
and B17 doses, among others (Davila et al., 2014).
Causes or risk factors
The risk factors or causes of ALL include radiation exposure, chemical exposures to
chemotherapy drugs and benzene, infection caused by human T cell lymphoma virus can give
rise to T-cell ALL (Zhou et al., 2014). The Epstein Barr virus can cause Burkitt lymphoma
(Rowe, Fitzsimmons & Bell, 2014). Certain inherited syndromes like Down, Klinefelter
syndromes, Ataxia-telangiectasia, can cause ALL (Narayanan, & Shami, 2012). Studies revealed
the role of the cell cycle genes CDK2, CCND1 and CMYC in the development of ALL

(Jayaraman & Jamil, 2012). Individuals with polymorphisms in the thymidylate synthase gene
are more prone to develop ALL (Akin et al., 2017).
Incidence rates
Estimates for ALL in the United States of America for 2017 were found to be 5970 cases
of ALL and about 1440 deaths. From 2010-2014, the number of ALL and death cases were 1.7
and 0.4, respectively per 100,000 men and women per year. About 0.1% of individuals are
diagnosed with ALL during some point in their lifetime. In 2014, approximately 81,837
individuals were living with ALL in USA (Www.cancer.org, 2017).
Resources
Resources that a patient can use include diagnostic tests like complete bone marrow
count, bone marrow aspiration or biopsy, genetic tests, among others. Other resources include
cord blood or bone marrow transplant, immunotherapy, Cellie cancer coping kits, support groups
who provide safe environments dedicated to give support, hope and education to the affected
individuals (Www.chop.edu, 2017).
Prevention
ALL can be prevented by decreasing exposures to radiation, avoiding alcohol, tobacco
consumption, use of drugs like marijuana. Cancer in general can be prevented by eating a healthy
diet and healthy weight and exercising (Www.who.int, 2017).

Conclusion
ALL affects the white blood cells of bone marrow and can give rise to severe
consequences that can eventually result in death. Proper prevention strategies and medications
are needed for early detection and treatment of patients.
