COMPARATIVE STUDY OF EFFICACY AND TOXICITY OF IMATINIB AND NILOTINIB BASED REGIMENS IN CML PATIENTS ABSTRACT: CML, a type of myeloproliferative disorder in which proliferation of bone marrow stem cells is found. Chronic phase, accelerated phase & blast crises are 3 phases of CML.Overall 90% of patients with CML Philadelphia chromosomes are present as a result of a t (9; 22) reciprocal translocation. This chromosomal abnormality is detected by cytogenetics, FISH (fluorescent in situ hybridization). BCR -ABL contains a protein that plays an important role in development of leukemia & it is BCR-ABL oncogene. Imatinib & Nilotinib are used for its treatment. Imatinib mesylate (Glivec, Novartis), a potent competitive inhibitor of the tyrosine kinase …show more content…
Leukemia is best described by increased, unregulated growth of myeloid cells in the bone marrow and assembly of these cells in the blood. A bone marrow disease majorly due to multiplication of mature granulocytes i.e neutrophils,eosinophils & basophils & their precursors. Chronic myeloid leukemia (CML) is a type of myeloproliferative disorder, associated with characteristic translocation called the Philadelphia (ph) chromosome [1]. In this chromosomal translocation, parts of two chromosomes (the 9th and 22nd) shift their places. [1] Consequently, part of the BCR i.e. breakpoint cluster gene from chromosome 22 is fused with the ABL gene on chromosome 9. (Abelson murine leukemia viral oncogene homolog 1 also known as ABL1 is a protein that, in humans, is encoded by the ABL gene). It results in the bone marrow making an enzyme, called tyrosine kinase, that results in too many stem cells to become white blood cells (granulocytes or blasts) CML has three phases. Respectively, each phase of CML is elucidated on the basis of number of blast cells in the blood &bone marrow.Chronic phase,accelerated phase,blast crises are the main stages of CML [2]. Authentic treatment for CML is a bone marrow transplant or an stem cell transplant.Rather there are also four major ways of treatment in CML such as treatment with tyrosine kinase inhibitors(TKI), myelosuppressive or …show more content…
The analysis of data demonstrated that patients belonging to different age groups taking imatinib and nilotinib have a continuous increase in their hemoglobin level. This shows our data is not in harmony with previous findings that, anemia is a main dose dependent side effect of imatinib and nilotinib. Increase in Hb values might be due to some concomitant use of iron therapy; ESAs, PCV etc. white blood cells count is also an important parameter to determine effectiveness of both drugs, results indicate that there is decrease in number of white blood cells during course of therapy. Platelets number in different age groups, taking imatinib, showed some irregularity while data obtained for patients taking nilotinib showed high variations. Neutrophils count is increasing and decreasing with irregularity in patients taking imatinib while neutrophils count in nilotinib therapy, in all age groups, is first decreasing and then again increasing. In general, lymphocyte count is increasing in both treatment groups but in some age groups irregularity has also been observed. There is a continuous rise and fall in monocyte number with both drugs. Eosinophils values are almost constant with imatinib but show decline with nilotinib. (graph 2,3) These findings are indicative of myelo-suppressive effect of imatinib and
C4564 Description: IC50: 3-AP is a ribonucleotide reductase inhibitor and iron chelator with antitumor activity. Ribonucleotide reductase, the rate-limiting enzyme for de novo DNA synthesis, is an excellent target for chemotherapy. Its increased activity in cancer cells is associated with malignant transformation and proliferation.
In vitro: Treatment of MM cells with SRT1720 inhibited growth and induced apoptosis in MM cells resistant to bortezomib therapy without significantly affecting the viability of normal cells. Mechanistic studies demonstrated that anti-MM activity of SRT1720 is associated with activation of caspase-3, caspase-8, caspase-9, poly(ADP) ribose

Her health being swiftly dropped despite assertive effort of treatment until her family decided to put her in palliative care. Acute Lymphoblastic Leukemia or ALL is one most common blood cancer in children less than 15-year-old of age. Jenny’s diagnosis is acute lymphoblastic leukemia. Ordinarily, blood cells are emerging from an immature cell or stem cell which can give rise to several different cell types. First phase of hematopoiesis or formation of blood
This paper will discuss a more in depth look into the symptoms, diagnosis process, treatment options, medications, prognosis, and ongoing research. What
Thrombocytopenia is a condition in which the body does not have a normal number of platelets in the blood. Blood is made up of three major cell types: red blood cells, which carry oxygen throughout the body; white blood cells, which help fight infection; and, platelets, which stick together at the site of a cut or wound to form a clot to stop the bleeding. People who have thrombocytopenia don’t have enough platelets to form a blood clot, and so they may bleed excessively when they are cut. (nhlbi.nih.gov, 2013) Blood cells and platelets are made in the bone marrow, which is the spongy tissue inside the bones.
In the late 1940s, scientific research began taking off as innovative technologies and diseases were being created and discovered. One important field of study during the time was cancer. Like many types of new research, there were a few problems getting the ball on the roll. One problem scientists faced was obtaining cancerous cells that would stay long enough to study. One scientist struggled with this until a particularly unique strand of cells came along.
T cells are produced to attack the antigens of tumors and B cells are produced to make antibodies that are specific to the antigens of a tumor. An older individual’s immune system could react at a slower
Cri-Du-Chat implies "Cry of the cat" in French. It gets its name from its most trademark highlight in infants were they contain a to a great degree specific deafening, weak, mewing cat like cry in the midst of right on time stages brought on by a sporadic change of the larynx that is regularly characteristic for the issue. This issue has various names to it as the Chromosome 5p-issue, Deletion 5p-issue, 5p short issue, Cat cry issue, and Monosomy 5p however most usually known as the Cri-Du-Chat Syndrome. Frequencies of this issue vary between 1 in each 20,000 - 50,000 live births general and as showed by the 5p less Society, around 50 to 60 adolescents are considered with cri du talk in the United States each year. Dr. Jerome Lejeune in 1963 depicted the issue as a hereditary inalienable issue associated with a midway cancelation of the short arm, or p area in chromosome 5 yet in %90 of patients the deletion is sporadic which infers it could happen subjectively and for it being basically natural is just not the circumstance.
Castleman’s Disease Immune System Castleman’s disease, also known as giant lymph node hyperplasia and CD, is a rare disorder that involves an overgrowth of cells in your body’s lymphatic system. It was first described by Dr. Benjamin Castleman in 1950. CD is not a form of cancer but is called lymphoproliferative disorder, which means there is an abnormal growth of lymphatic cells and is similar to cancers of the immune system. Although it may not be a type of cancer one of the two forms, called multicentric Castleman’s disease, acts just like lymphoma. Many people with multicentric Castleman’s disease actually develop lymphomas.
In high doses, it is a heavy-hitting chemotherapy drug that
The shape of the red blood cell is irregular in this case which means that the cell cannot flow the way they are supposed to. This can cause a blockage and backup of blood flow and cells and this generally causes pain for the person who is suffering with the disorder. Sickle cell anemia is inherited and passed down through families. The symptoms of Sickle cell include a delay in growth, vision problems, and pain. The pain usually comes and goes.
Lymphoma is a cancer of the blood that occurs when white blood cells acts abnormally (Lymphoma Research Foundation, 2012). Normally white blood cell protects the body from disease and infection(Lymphoma Research Foundation, 2012). Lymphoma can occur in the lymph nodes, bone marrow, spleen, or other organs (Lymphoma Research Foundation, 2012). There is a high chance of survival after treatment for this specific cancer (Balentine, Jerry, 2015). 20,170 people will die from lymphoma in the U.S each year (Medical News Today, 2015).
ACUTE LYMPHOBLASTIC LEUKEMIA BACKGROUND Acute lymphocytic or lymphoblastic leukemia (ALL) is an aggressive cancer of the bone marrow, specifically affecting the immature lymphocytes that is fatal within weeks if left untreated. Leukemia cells are aggressive, rapidly reproducing, and do not mature appropriately. There are two types of ALL based on the affected lymphocytes, B lymphocytes or T lymphocytes. B lymphocytes are important to the immune system as they protect the body from invaders (e.g., viruses, bacteria, fungi) and make antibodies that tag these intruders and trigger the immune system to destroy them. T lymphocytes can directly destroy invades but some types also boost or slow the immune system depending on their specific subtype.
Leukaemia is referred to as the cancer of blood cells; the bone marrow produces abnormal white blood cells known as leukaemia cells and leukemic blast cells – these cells do not die when they are old or damaged, because of this, the leukaemia cells build up and outnumber normal blood cells (National Cancer Institute, 2013). There are numerous types of leukaemia meaning that symptoms, diagnosis, treatments, and social and economic effects are different for each type of cancer. The four most common types of leukaemia include acute lymphoblastic leukaemia (ALL), acute myeloid leukaemia (AML), chronic lymphocytic leukaemia (CLL), and chronic myeloid leukaemia (CML) – acute leukaemia refers to the rapid development of leukaemia cells, often becoming
