The Genetic And Clinical Risk Factors For Explosion Phase Progression Of Chronic Leukemia

Acute Lymphoblastic Leukemia, is the disease that affects children the most and because of the abnormal cells that are immature white blood cells which cannot help the body fight infections cause children with the disease to often get infections and have fevers (National Cancer Institute, 2002, p. 1). The symptoms that the patient with ALL may have depend on the number of abnormal cells of the patient where exactly the cells collect. Children patients with ALL have low amounts of healthy red blood cells and platelets, which cause less oxygen to be carried through the body because of the lack of red blood cells. Patients at times may look pale, feel weak, and tired causing bleeding and bruising very easily because of their lack of enough platelets. This condition is called anemia. Anemia is very much common in patients with acute lymphoblastic leukemia. Fever, fatigue, bone or joint pain, tiny red spots under the skin called petechiae are a couple of symptoms that the disease ALL has. Headaches with, or without vomiting also may occur if patient happens to have abnormal cells collecting in the brain or spinal cord (National Cancer Institute, 2002 para. 2).

Leukemia is a type of cancer that affects the production of white blood cells. The cells that are produced are abnormal and cannot complete their function effectively. This research paper will discuss leukemia, and assess how it affects the anatomy and physiology of the affected patient. The paper will compare the anatomy and physiology of a normal human being to that of a patient with leukemia. The paper will also consider several parameters that are of importance when talking about leukemia, such as statistics, signs, and symptoms of the condition, causes, prevention, diagnosis, treatment, and prognosis. Blood cells are manufactured in the bone marrow and lymphatic system. The bone marrow is the soft and spongy part tissue of the bones. In patients with leukemia, the white blood cells are produced abnormally. There are three major types of white blood cells: lymphocytes, monocytes, and granulocytes. There are several types of leukemia: chronic myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, and chronic lymphatic leukemia. These types of cancers differ in the manner in which the cancer originates and progresses.

Chronic Myeloid Leukaemia is a hematopoietic proliferative disorder associated with a specific defect in the gene (Ciesla 2007, pp. 189). The gene defect is caused due to the translocation of the genetic material between chromosome 9 and chromosome 22 (t9: 22). The translocation prompts to the development of a hybrid gene BCR-ALB in the Philadelphia chromosome, or Ph1. Therefore, this fusion gene mutation affects the maturation and differentiation of the haematopoietic cells (Ciesla 2007, pp. 189). However the introduction of a BCR-ALB particular tyrosine kinase inhibitor, Imatinib has significantly enhanced the survival rate of the patient with chronic myeloid leukaemia (Hochhaus, et al.2015). This essay will briefly describe the diagnosis, treatment and future strategies for chronic myeloid leukaemia.

A mother of a healthy 7 year old boy notices he is pallor and has small hemorrhages (petachiae) on his limbs. After completing a physical examination, Steven’s pediatrician requested a blood panel to be on the safe side and it showed that he was extremely anemic. His hemoglobin and platelet count was well below the average and in addition his white blood count was not at the recommended level for his age. A referral to a Hematology specialist resulted in a bone marrow biopsy, which concluded in a diagnosis of Aplastic anemia. Unfortunately Steven’s bone marrow was not making the cells and precursors he needed to generate mature blood cells or what is a complete process of hematopoiesis. The best option Steven had was an allogeneic bone marrow

The diverse presentation of acute leukemia subtypes often makes specific disease subtypes difficult to recognize. Few, however, are as clinically challenging for the practicing hematologic malignancy physician to recognize as acute panmyelosis with myelofibrosis (APMF). APMF is a rare type of acute myeloid leukemia (AML) that manifests with a rapidly fibrotic bone marrow and progressive cytopenias. Early recognition is essential, as APMF can quickly turn fatal, a consequence of the disease’s ubiquitous pathologic features, aggressive clinical course, and poor response to traditional treatments. Pathologically this AML subtype is recognizable for its heavily fibrotic marrow, increased overall cellularity, immaturity of all cell-line lineages, abnormal megakaryocyte population, and lack of driver mutations. Clinical features include lack of spleen enlargement, bony pain, fevers and other features associated with systemic inflammation.

The physician can obtain Bone marrow samples through bone marrow aspiration and biopsy checks that are often done simultaneously. The samples are obtained from the pelvic back bone or from the sternum or breastbone. An aspiration and biopsy are used in helping to diagnose leukemia. The process can be repeated to determine if the illness is responding to treatment. Routine examination under a microscope is majorly important to determine what the proportion of cells present in the bone marrow are blasts. A diagnosis of Acute Lymphocytic Leukemia generally necessitates that at least thirty or twenty percent of the total cells in the bone marrow are blasts. Normally, blasts are rarely over five percent of bone marrow cells.

Chronic myelocytic (or myelogenous) leukemia (CML) is a rare disease worldwide 2000); however, the innovative advances and successes of CML’s targeted-molecular therapy have kept CML “at the forefront of scientific attention” (Lee 2000). Like other forms of leukemia, CML is a type of cancer that starts in the blood-forming cells of the bone marrow. In particular, CML begins in myeloid stem cells, the cells that differentiate into platelets, red blood cells, and some white blood cells (e.g., granular leukocytes). These cells undergo genetic changes that cause white blood cells to not function normally and divide rapidly. The resulting abnormal leukemia cells build up in the bone marrow and interfere with the production of normal blood cells (platelets, RBCs, and granular leukocytes). Additionally, leukemia cells move into the blood stream and can spread to other organs (e.g., spleen). Unlike acute leukemia, which progresses very quickly, chronic leukemia progresses more slowly and can take a long time before causing health problems (American Cancer Society). According to the American Cancer Society, “one person in 55 will get CML in their lifetime in the United States” (American Cancer Society). The occurrence of the disease increases with age (average age of CML diagnosis: 64 years) and is rarely seen in children. For an unknown reason, slightly more males have CML as compared to females. The one potentially controllable risk factor is exposure to

Most people may believe leukemia is cancer of the blood it really isn’t as stated in the book of “Leukemia” by Melanie Ann Apele “Although leukemia is not exactly “cancer of the blood,” it is cancer of the cells and tissues that make the blood” (Apele THE YEAR). In this research article I will be discussing the severity of leukemia, the type of leukemia most people get, and the best treatment options for patients with leukemia. Most blood cells form in the bone marrow, in leukemia cancerous blood cell form and take over the healthy blood cells in the bone marrow and is a very deadly cancer but it is one of the least cancers talked about. In a patient who has leukemia, the bone marrow makes abnormal white blood cells. These abnormal blood cells

Leukemia is a malignant disease of your blood cells caused by excess of white blood cells also known as leukocytes in the blood. The abnormal accumulation of white blood cells that starts in the soft and inner part of the bone (bone marrow) often moves quickly into the blood and spread to the other parts of the body that causes problems as they crowd out the red blood cells and platelets in which your body needs to be healthy. Blood has three types of cell: White blood cells are the cells of the immune system that fight infection, protecting the body against both infectious disease and foreign invader. Red blood cells which is made in the bone marrow carries oxygen to be transported around the body and also remove carbon dioxide from

However, patients that have chronic stage have an onset and more indolent clinical course which usually last two to six years. Survival rates of patients with chronic leukemia also increases due to diagnostics sensitives and if patient are diagnosed at earlier stages in their disease. In patients with acute leukemia, patients show a loss in normal bone marrow function and often experience thrombocytopenia. Usually there are various normal circulating white blood cells are diminished in number, resulting in neutropenia. In chronic leukemia the anemia is often mild when presented. Platelet count is normal and white blood cell counts are often elevated to very high (>50,000/uL)1. Speel live or lymph nodes have also been seen to show enlargement, however, they are more consistently seen in patients with chronic leukemias. Studies have suggested that the origins of leukemia appears at the genetic level , as most cases are to be related to mutation and altered expression of oncogenes and tumor suppressor genes. Since most oncogenes regular proliferation and differentiation in a cell an abnormal oncogene or tumor suppressor gene induced by translocation results in unregulated cellular maturation.. Host and environmental factors have also been associated to leukemias however they are not entirely understood.

Leukemia is a cancer of the bone marrow, a malignant progressive disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leukocytes. These suppress the production of normal blood cells, leading to anemia and other symptoms.

Acute Promyelocytic Leukemia is the development of blood clotting or bleeding difficulty. It is where the bone marrow contains too much of promyelocytes cells, and the bone marrow has no space for healthy cells which go out of the body by bleeding. Acute Promyelocytic Leukemia is not genetic it is a DNA mutation. Acute Promyelocytic Leukemia affects the chromosomes 15 and 17. Promyelocytes is a granulocyte precursor that belongs to the granulocytic series. It is intermediate between myeloblasts and myelocytes, and it embraces some undifferentiated cytoplasmic granules. Some signs and symptoms of Acute Promyelocytic Leukemia are bleeding excessively with any small cut or any cut, blood in the urine, paleness, poor appetite, heavy nosebleeds,

Under the supervision of Dr. Alan Lichtin. I wrote the manuscript for a blood work project that looks at unusual MRI appearance of leukemic relapse. I also was responsible for getting the images from diagnostic radiology and pathology labs. The blood work was submitted to Blood Journal on February

In MDS/MPN cases, either normal karyotype or MDS-related chromosome abnormalities have been reported. A high percentage of MDS/MPN patients harbor identifiable mutations in genes recurrently mutated across myeloid neoplasms when undergoing either targeted-panel mutation analysis or whole-exome sequencing with next-generation sequencing technology but no disease defining mutations have been reported [9]. Mutation analysis has emerged as an important ancillary test to accompany a diagnosis of MDS/MPN; especially in the absence of cytogenetic chromosome abnormalities because these may serve as a critical clonality marker confirming its neoplastic nature essential for the diagnosis of a myeloid neoplasm. CMML, among the most well-documented in this group, harbor mutations in genes that include SRSF2, TET2, and ASXL1 in up to 50% of cases, respectively[9, 10]. Mutations in ASXL1 have also been reported as an independent prognostic factor along with other clinicopathologic parameters in a multivariable model [10]. Mutation analysis including these genes can greatly facilitate the diagnosis and prognostic stratification of CMML [11]. However, a more conservative approach toward the mutation analysis results is warranted in older individuals lacking definitive evidence of a myeloid neoplasm, since it is known the presence of mutations in similar set of genes can be identified in such patients [12,

Leukemia is an abnormal production of white blood cells (WBC) also known as leukocytes. When the leukocytes are functioning correctly it helps fight off infections. Unlike the regular leukocytes, abnormal leukocytes do not die when they are supposed to and this causes a problem in the balance of the blood. As this imbalance occurs, it becomes more difficult for the normal healthy blood particles to work correctly (Story, 2012). There are four different types of leukemia: acute myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, and chronic lymphoid leukemia.
