The variability in clinical presentation spasms under rib cage purchase 50 mg voveran with visa, aggressiveness muscle relaxant 2632 order cheapest voveran and voveran, and patterns of treatment failure suggests distinct genotypes and phenotypes identification muscle relaxant gel order generic voveran, which can help future treatment strategies spasms rib cage buy voveran 50 mg on-line. There is an increasing interest in this therapeutic strategy on the part of pharmaceutical and bio-pharmaceutical companies muscle relaxant liver disease proven 50 mg voveran, consumers spasms during mri order voveran 50 mg on-line, and third party payers. Consequently, the level of clinical trial activity surrounding personalized medicines is intensifying as sponsors seek ways to target their therapies to patient populations that would most benefit from them. The idea of applying such a model to our studies was generated during the research that we conducted in our projects. We have noticed that between different proteins and genes is a very close relationship, which depends on the tumor type, cell grade and staging. Following a study of a large number of articles published in the international databases we observed that other researchers have drawn the same conclusion. Tissue samples and blood Samples were obtained with the consent of 93 patients, consisting of histopatologically confirmed colorectal adenomas. Samples were obtained during colonoscopy with biopsy forceps, by harvesting at least four fragments from all the quadrants of the pathological tissue. After surgical resection, tumor tissues were cut in small pieces, frozen immediately in liquid nitrogen and stored at 800C until they were analyzed. For the initial patients group, only 75 patients who had at least 75% tumor cells were taken in consideration for molecular biology analyses. Clinicopathological characteristics the medical records of all 93 patients provided their birth date and sex, and the following parameters: tumor location, tumor size, lymph node metastases, pathological stage, vascular and neural invasion and tumoral differentiation grading. Our study has not taken into consideration the diet, because most of the patients do not know the food properties or they use food with pro-carcinogen potential. Regarding the diet, we consider that the patient instruction is extremely useful and has to be done by the surgeon doctor after the surgical treatment and then by the family doctor. This approach allows both secondary prophylaxis and control of possible relapses/ recidivists. A monitoring of the patients included in the study will shows the efficiency of medical control 98 Mutations in Human Genetic Disease and the conscious of this mortal disease. In the studied lot of patients we have not registered cases with relapse, and we cannot predict their future behavior. Immunohistochemical expression by immunofluoresce of the studied proteins Because the interpretation of immunohistochemistry analyses remains the basic of anatomic pathology, in our study we first evaluated the protein expression of the key point proteins that were taken in our study. Unlike the normal histopathological analyses, our evaluation was based on protein fluorescent signal which, from our point of view, is more specific than classical immunohistochemistry. It is one of the four muscle actin isoforms, a protein involved in supporting basic contractile apparatus in muscle cells. This expression can be found in vascular cells, intestinal muscularis mucosae and muscularis propria, and in the stromal tissue. In normal tissue, the immunofluorescence signal is strong (+3) around tumor crypts, in the vessel walls and stromal smooth muscle Genotype-Phenotype Disturbances of Some Biomarkers in Colorectal Cancer 99 fibers. Smooth muscle, used as a positive marker for immunofluorescence signal, have immunofluorescent signal in blood vessels, intestinal muscularis mucosae and muscularis propria, and in the stromal tissue. On section obtained from patient 3 we can observe a weak intensity on the apical part of epithelial cells and loss of signal, too. In the apical half of the fluorescent signal crypt, epithelial cells and infiltrated cells disappeared (-). In normal colorectal tissue, catenin expression appears on the membrane of epithelial cells. A normal expression with immunofluorescent signal on cytoplasm and on the border of crypts can be observed on the section from patient 8. On section from patient 3 we can observe an over-expression in the cytoplasm/ nucleus of epithelial cells and loss of expression in the membrane. We can observe how the fluorescent signal on the membrane of epithelial cells gradually decreases in intensity during the tumor progression, along with increased fluorescent signal by over-expression in cytoplasm (in 28 patients) and in the nucleus (in 5 patients). Regarding E-cadherin expression, colorectal tumors showed a heterogeneous type of expression compared to the normal colorectal epithelium in which E-cadherin expression is present on the basolateral membrane to the whole length of the glandular crypts and on the intercellular membranes. In the case of lymph nodes analyses, Genotype-Phenotype Disturbances of Some Biomarkers in Colorectal Cancer 101 Figure 4. A normal expression with immunofluorescent signal on the membrane of epithelial cells can be observed on section from patient 70. In the case of patient 74 we can observe a reduced/ loss of expression in the epithelial cell membranes. On patient 73 an over-expression in the cytoplasm of epithelial cells and in some infiltrating cells was noticed. On patient 60 we can observe an over-expression on the epithelial cells from the crypt foci. On other sections from patient 60 over-expression was observed only on the apical pole of epithelial cells. On patient 43 we can observe an over-expression on the membrane of epithelial cells from the crypt foci. It is also a useful tool for the diagnosis of genetic diseases characterized by large genomic rearrangements. In order to perform the test on blood and tissue samples in the first step of our analyses we optimized the procedure for the specific genes. Genotype-Phenotype Disturbances of Some Biomarkers in Colorectal Cancer 105 Figure 9. The GeneMapper results were exported in Coffalyzer software for normalization and the relative probe signals were calculated by dividing each measured peak area by the sum of all peak areas of the sample. This patient showed two deletions, in blood and in the tumour, in the promoter 2 and mutation 1309 region, although the individual did not show microsatellite loci alteration. In all studied cases we observed that 12% (9/ 75) of patients had a mutational profile. Insertions were observed in 13% of cases (10/ 75) of cases in the promoter region and 13% (10/ 75) of patients have shown presence of wild type mutation 1309 (Figure 10). Insertion was observed at exon 4 in 30% (6/ 20) of patients and in 20% (4/ 20) of patients at exon 10. Loss of heterozygosity was observed at exons 08 and 13 in 20% (4/ 20) of patients for each exon (Figure 11). Duplication at exon E13B was observed in 40% (6/ 15) of patients and at exon 20 was observed in 20% (3/ 15) of patients. As well as duplication, loss of heterozygosity was observed in principal to exon 13B in 40% (6/ 15) patients (Figure 12). Out of these, in 50% (10/ 20) of patients we observed insertion at the exon 3, in 20% (4/ 20) of patients at the exon 08, in 40% (8/20) of patients at the exon 17, in 40% (8/ 20) of patients at exon 25 and in 30% (6/ 20) of patients at exon 28 (Figure 13). Genotype-Phenotype Disturbances of Some Biomarkers in Colorectal Cancer 107 Figure 11. For those patients who presented deletion/ duplication at the interested genes, in order to have a more accurate mutational analysis we decided to analyze the microsatellite instability. In case of homozygosity, the two alleles are identical as dimension, and the corresponding picks are overlapped. Previous studies showed that the 1p36 region frequently present allelic loss in various cancers, such as colon cancer, neuroblastoma, hepatocellular carcinomas, lung cancer, and breast cancer. Allelic imbalance/ loss of heterozygosity appear to be a more frequent alteration than microsatellite instability in adenocarcinomas. Allelic imbalance analyses at the microsatellite loci D17S1323, D17S1322, and D17S855, which localize to introns 12, 19, and 20, respectively, indicates that 86. Another observation is that for microsatellite marker D17S1327, all individuals have a homozygote profile. Comparative analyses of the fifteen microsatellites markers By comparative analysis of all 15 microsatellite markers, we found that: a) 7/ 93 patients have instability on all three genes (7. Despite the construction of D5S421 microsatellite marker, in our analyses we Genotype-Phenotype Disturbances of Some Biomarkers in Colorectal Cancer 113 Table 3. According to our expectation, the other two markers located under D5S82 marker, have also a good informative percent: 58. We observed a close relationship in between different proteins and genes, which depends on the tumor type, cell grade and staging. These patients have a better prognosis than the patients with positive tumours (Buhmeida A.

In parallel, extensive in-vitro and in-vivo studies widened our understanding of the molecular basis of heart development. These studies resulted in large sets of candidate genes and molecular pathways involved in heart development. Other mutations might yield totally defective proteins, yet be compensated for by other proteins in interlinked pathways. Current research explores all of these mechanisms with a wide array of technologies that are better than ever, and hence the future decade promises a near complete understanding of heart development and the genetic basis of Congenital Heart Disease. This chapter covers the genetics of syndromic and non-syndromic congenital heart disease. It discusses all genes that have been associated with congenital heart disease in humans with depiction of the spectrum of mutations and the genotype-phenotype correlations for each. Current technologies and strategies used to understand the genetics of congenital heart disease are also discussed. Classifications, anatomy, and clinical significance Congenital heart disease encompasses a broad category of anatomic malformations, which can range from a small septal defect or leaky valve to a severe malformation requiring extensive surgical repair or leading to death such as a single ventricle. Because of the wide diversity in the anatomy of the cardiac malformations, several detailed morphological classifications were also developed. Other classification systems are radiologic based on echocardiography or magnetic resonance imaging, hemodynamic based on shunts and circulations in the heart, or embryological based on the presumed origin during heart development. Pediatric cardiologists often end up using different terminologies to describe similar defects because of their complexity. Extremely rare complex malformations are also sometimes described and run in families while their cause remains unknown. The same single gene mutation has been shown to cause a variety of cardiac defects, even within the same family. The genetic background of the individual, in-utero environment, epigenetic changes, and embryological hemodynamics and physiology are all possible causes of this phenotypic heterogeneity. Small malformations such as tiny septal defects that are expected to correct on their own or to not cause any complication are simply observed. Developmental genetics of congenital heart disease Heart development is crucial to understand because its molecular basis is evolutionary conserved as depicted by studies in several model organisms. Heart development is a complex process regulated by combinatorial interactions of transcription factors and their regulators, ligands and receptors, signaling pathways, and contractile protein genes among others. The differential expression of each of these genes at unique stages of development and in different areas of the heart is responsible for the normal development of the heart. Any disruption in these genes will result in congenital malformations of the heart. This molecular program for heart development has been a heavy field of research, yet our knowledge is far from being complete. The heart is the first organ to develop in the embryo at the second week of gestation when pre-cardiac lateral plate mesoderm cells migrate towards the midline of the embryo and form two crescent-shaped primordia, which fuse to form a beating heart tube at week 3. Within only few days the heart tube folds on itself in a process known as looping. This is the first event in the organogenesis of the embryo that manifests left-right asymmetry and is believed to be at the origin of the laterality program of the embryo. This requires the differentiation of myocytes into two different subtypes, atrial and ventricular.

A short exposure to colcemid is usually used (but see the variation described in Chapter 4) spasms toddler voveran 50 mg on-line, which means that there is a strong chance of missing the peak of divisions when it happens muscle relaxant 114 order voveran 50 mg free shipping. However muscle relaxant g 2011 buy genuine voveran line, if this method does work muscle relaxant id discount generic voveran canada, it can give good quality chromosomes spasms kidney stones purchase 50mg voveran with visa, so it is always worth doing if there is sufficient material muscle relaxant cyclobenzaprine cheap voveran 50 mg with amex. Commonly used synchronizing agents are methotrexate (Ame thopterin) (10), fluorodeoxyuridine (11) and excess thymidine (1). The first two tend to be better for myeloid disorders, with the last being better for lymphoid disorders. Despite this, many labora tories routinely allow only 4 or 5 h of release before adding colcemid. Mitogen-Stimulated Cultures Mature lymphocytes do not divide spontaneously, but will trans form (become capable of division) as part of their immune response. Certain reagents, termed mitogens, are regularly used in cytogenet ics studies to stimulate lymphocytes into division, and some of these are described in Chapter 9. However, the disease may affect lym phoid cells so that they are not capable of responding to mitogens, or the treatment may suppress the immune response; in these cases mitogens will not be effective in producing divisions. If the lymphocytes have already been transformed, for example, because the patient has an infection, then lymphocyte divisions can be found in unstimulated cultures. Immature lymphocytes that are still dividing do not usually enter the circulation and are rare in the normal, healthy state, but can be common in hematologic malig nancy when the bone marrow organization is in disorder. Introduction Malignant myeloid disorders have broadly similar responses to cytogenetic techniques and many have similar chromosome abnor malities. A proportion of the premalignant group may progress to acute leuke mia but they are serious diseases in their own right, often difficult to treat, and may be fatal. They are all clonal disorders, that is, the bone marrow includes a population of cells ultimately derived from a single abnormal cell, which usually tends to expand and eventu ally suppress or replace the growth and development of normal blood cells. In many cases the disease is chronic, slowly evolving, and the symptoms can be controlled for many years with relatively mild cyto toxic treatment. This may be because the cells with abnormal chromosomes are in too low a proportion to be detected by a conventional cytogenetic study (in which only 25 divisions may be analyzed). This may be because the prolonged antecedent disorder has compromised the ability of normal myeloid cells to repopulate the marrow. The abnormalities found include those seen in all myeloid disorders but with deletion of the long arms of chromosome 20 being most com mon. The cytotoxic treatments do carry the Myeloid Disorders 25 a small risk of promoting a progression from premalignancy to malignancy, or the development of secondary malignancy. This is a rare condition, and using conventional cytogenet ics studies, no clone is found in most patients; in one large series only 29/170 (5%) of cases had a clone (2). Myelofibrosis and Agnogenic Myeloid Metaplasia the bone marrow is replaced by fibrous tissue and blood cell pro duction may take place in extramedullary sites (outside the bone marrow) such as the spleen, which causes the spleen to enlarge. Deletion of part of the long arms of a chromosome 13 is common, as is a dicentric chromosome dic(1;7)(q10;p10), which results in gain of an extra copy of the long arms of chromosome 1 and loss of the long arms of a chromosome 7. This abnormal chromosome is similar in appearance to a normal chromosome 7, and can be missed by an inexperienced cytogeneticist. In more than 90% of cases the Philadel phia translocation (abbreviated to Ph) is present, usually as a simple translocation between chromosomes 9 and 22, t(9;22)(q34. The chronic phase is of variable duration; it may be over before the patient is first diagnosed, and it can last for 15 yr or more. In some patients, chronic phase bone marrow can be harvested and stored for use as an autograft at a later stage. Although this procedure can restore the patient to chronic phase disease, it tends to be of shorter duration. It has been found that treatment with interferon increases the number of Ph-negative divisions in some patients, and a few have become entirely hematologically normal, although probably not cured. It is useful to have a cytogenetic study at diagnosis, against which to compare the results of subsequent studies. There has not been agreement about the prognostic effect of secondary abnormalities identified at diagnosis, but most of them are not thought to be ad verse clinical signs (7). Some abnormalities, such as trisomy 8 and gain of an extra der(22), have been associated with a poorer progno sis. However, if secondary abnormalities are detected during the course of the disease, then this is a stronger indication that accelera tion of the disease is imminent. Cytogenetic studies of large num bers of divisions have shown that in some cases these late-appearing abnormalities were present at diagnosis, but at a very low incidence (B. Examples of recurrent abnormalities in myeloid disorders, par ticularly illustrating some that can be subtle. For example, the isochromosome for the long arms of a chromosome 17 (now known to be a dicentric chromosome with breakpoints at 17p11) (10) is associated with myeloid blast crisis, and abnormali ties of 3q21 and/or 3q26 (Fig. The Myelodysplastic Syndromes Historically there have been many terms for these disorders, including dysmyelopoietic syndrome, preleukemia, subacute leu kemia, and smouldering leukemia. Transformation into acute leu kemia does occur, but these are not merely preleukemic conditions; they are malignant, clonal diseases in their own right. They have abnormal growth (dysplasia) or failure of maturation of one or more cell lineages in the bone marrow, usually resulting in a deficiency of one or more blood components. For example, dyserythropoiesis indicates abnormalities of the cells that produce erythrocytes (red the Myeloid Disorders 29 blood cells), which results in anemia. All three lineages may be involved (trilineage dysplasia), leading to pancytopenia (inadequate numbers of all blood elements: red cells, white cells, and platelets). It may also be a side effect of treatment for other disorders, such as lithium for depression. In all these areas of diagnostic uncertainty, cytogenetic studies can help: If a chromosomally abnormal clone is found, this is very strong evidence that the condition is malignant. The incidence of clonal chromosome abnormalities increases with each subtype, from as low as 10% up to nearly 50%. Failure to find a clone may not mean that there is no cytogenetically abnormal clone present, but rather that it may be at too low a level to be detected by a conven tional cytogenetic study. The number of blasts is variable and is not used to define or subdi vide this category. There are three main causes: (1) It may be secondary to a major exposure incident, for example, radiation or poisoning with benzene. Because there are usually very few cells in the sample sent to the cytogenetics laboratory, it is a difficult disease for cytogenetic study. It may be no coincidence that these abnormalities are generally confined to granulocytic cells and are associated with a good prognosis, while most other abnormalities tend to occur in all kinds of myeloid cells and are broadly associated with a poorer prognosis. M2: Myeloblastic leukemia with maturation; the most common abnormality is t(8;21)(q22;q22). However, there were very few long-term survivors before the introduction of modern intensive chemotherapy. A very common abnormality secondary to t(8;21) is loss of an X chromosome in female patients or the Y chromosome in males. Another common secondary abnormality is dele tion of part of the long arms of chromosome 9. Although they are so closely associated with t(8;21), the clinical significance of these secondary abnormalities is not known. Several the Myeloid Disorders 33 published series have reported contradictory effects on prognosis (21). Molecular evidence of persistence of t(8;21) has been found in some patients more than 7 yr in remission, with no evidence for tendency to relapse (24). The quoted breakpoints on chromosomes 15q and 17q vary widely among different publications; the author favors those proposed by Stock et al. In one study (23) (in which all secondary abnormalities were combined) they appeared to have no effect, but in others (25,26) the co-occurrence of trisomy 8 reduced the prognosis from good to stan dard. It would seem reasonable to expect that different secondary abnormalities have a different effect on prognosis. Unlike the case with t(8;21), the detection of t(15;17) in remis sion is usually a sign of imminent relapse. Because the chromosome quality of t(15;17)+ cells is often poor, and the abnormality is diffi cult to see with poor-quality chromosomes (Fig. Molecular methods appear to be too sensitive for clinical use at present, as they detect residual disease in more patients than those who proceed to relapse (27). However, the typical t(15;17)(q24;q21) could still be recog nized; the abnormal chromosomes are indicated with arrows. M4: Myelomonocytic leukemia; t(8;21)(q22;q22) also occurs, although at a lower frequency than in M2. A well characterized sub type, M4eo (M4 with abnormal eosinophilia), is strongly associated with inv(16)(p13q22) (Fig. This abnormality has been associated with a relatively good prognosis, although with a tendency to central nervous system relapse. The inversion is not easy to identify in poor quality chromosomes, espe cially because the heterochromatic region of chromosome 16 varies considerably in size. A common secondary abnormality is trisomy the Myeloid Disorders 35 22, so if this is seen the 16s should be carefully checked. There have been conflicting reports as to whether or not a trisomy 22 as the sole abnormality is likely to indicate the presence of a cryptic inv(16) (20,29). Genes located at 8p11 are also involved in translocations with many other chromosomes (14,32), which seem to specify the type of malig nancy produced. This is a subtle abnormality and can be missed unless the 9p and 11q regions are specifically checked (Fig. M5b (monocytic leukemia) is not closely associated with any particular cytogenetic abnormality. M6: Erythroleukemia: no specific cytogenetic abnormality, but about 25% of all occurrences of t(3;5)(q21-25;q31-35) are found in M6. People with Down syndrome (constitu tional trisomy 21) have an increased risk of developing leukemia, and often this is of the M7 type. A highly specific abnormality, t(1;22)(p22;q13), is associated with M7 in infants (34,35). Abnormalities of chromosomes 5 and 7 usually take the form of loss of the whole chromosome or deletion of part of the long arms. In most cases other chromosome abnormalities are also present, and the prognosis is generally poor. The prog nosis is generally regarded as being intermediate or poor, and it has been claimed that the prognosis depends on what other abnormali ties are present (36). If the chromosome morphology is poor, tri somy 10 (a rare finding but one that may indicate a poorer prognosis) may be missed on the presumption that it is the more common tri somy 8. As previously mentioned, abnormalities of bands 3q21 and 3q26 are very frequently associated with dysmegakaryopoiesis; these ab normalities have been found in various hematologic disorders and generally indicate a poor prognosis (37). This translocation was thought to be linked with basophilia as inv(16) was associated with eosinophilia; it is now known that there is an association, but it is not nearly so specific and no basophilia is detected in many cases. The genetic abnormality in most of the remaining 30% of cases has still to be determined. In some cases, cryptic rearrangements of the genes involved in the commonly occurring translocations already described have been demonstrated (39). However, several laboratories were unable to confirm these findings (42) and it now seems likely that the inci dence of cryptic versions of these translocations is rare. How ever, the downside is that a smaller but similarly increasing number of patients is living long enough to suffer unwanted side effects of that treatment. Whether or not some patients are inherently at greater risk of developing more than one kind of malignancy, there is an inescapable association between intensive, genotoxic therapy and the emergence of a second cancer. These tend to fall into one of two classes, depending on the type of treatment for the primary disease: 1. This typically arises at least 3 yr after 38 Swansbury commencement of exposure, although this latent interval can be much shorter after very intensive treatment, such as for bone marrow transplant. Cytogenetically, abnormalities of chromosomes 5 and 7 are most common, usually as part of a complex clone. How ever, this prognosis is more likely to be a consequence of the pres ence of poor-risk cytogenetic abnormalities than being directly related to the phenotype (43), as the most common cytogenetic ab normality is the Philadelphia translocation, t(9;22)(q34;q11) (44). Unlike in the chronic lymphoid disorders, there is no need for mitogens to include cell division. This has the consequence that a large proportion of patients is denied the diagnostic and prognos the Myeloid Disorders 39 tic benefit of knowing the cytogenetic abnormalities that are asso ciated with their disease.

Cytogenetic Techniques for Myeloid Disorders 43 4 Cytogenetic Techniques for Myeloid Disorders John Swansbury 1. Introduction Chromosomes are prepared from dividing cells (mitoses), as at metaphase, just before division, they shorten and become recog nizable, discrete units. The cells are arrested and accumulated in metaphase or prometaphase by destroying. The cells are treated with a hypotonic solution to encourage spreading of the chromosomes. They can be stained immediately, but are usually first treated to induce banding patterns on the chromosomes to assist in their iden tification. Materials Many of the reagents and chemicals used are harmful and should be handled with due care and attention. However, using larger tubes (such as 20-mL Universal tubes) or tissue culture flasks also works well for cultures, and has the advantage of allowing a greater surface area at the interface between medium and cell pellet, which bone marrow cells seem to prefer. For setting up cultures, the pipets must be sterile; for harvesting cultures they do not need to be sterile. Glass pipets should not be used because of the risk of needlestick injury and also because fixed cells will adhere to the glass.

Historical warnings of future food inse impacts of climate variability and change for the united states: curity with unprecedented seasonal heat. Introduction lmost half of the energy used to gen erate electricity in the united states comes from burning coal, as shown in a Figure 1. Coal is a major component of the economy and forms the center around which political, economic, health, and environmental considerations coalesce. With the passage of time, more and more adverse health effects have been attributed to the increasing reliance on coal. In the year that followed, black smoke ardous air pollutants (HaPs) emitted from coal concentrations declined by 70% plants, but did not address particulates or oxides of nitrogen and sulfur (noX and soX), now referred to as criteria pollutants. Initially, coal powered the steam engine and therefore became the essential fuel for transportation during the nineteenth century, when steamships and railroads fourished. By the middle of the 1800s, coal replaced charcoal in the production of iron and steel, thus flling another key role in driving industrialization. Coal became a source of energy for the generation of electricity at the end of the 1800s. High-carbon coals produce the exemplifed by the dozens of new coal plants cur most energy when burned and low-carbon coals rently in the planning or construction stage.

The four major types of leukemia are {{Acute myeloid leukemia {{Chronic myeloid leukemia {{Acute lymphoblastic leukemia {{Chronic lymphocytic leukemia. Acute leukemia is a rapidly progressing disease that produces cells that are not fully developed. Chronic leukemia usually progresses slowly, and patients have greater numbers of mature cells. With acute lymphoblastic leukemia, the cancerous change begins in a marrow cell that normally forms lymphocytes (a type of white blood cell). With chronic myeloid leukemia, the cancerous change takes place in a marrow cell that normally forms red blood cells, some types of white blood cells and platelets. Chronic Myeloid Leukemia I page 5 The four main types of leukemia are further classifed into subtypes. Knowing the subtype of your disease is important because your treatment plan is based, in part, on the subtype. As a result, chronic phase myeloid leukemia is generally less severe than acute leukemia, and often patients do not have any symptoms when diagnosed. This efect has been most carefully studied in the survivors of the atomic-bomb blast in Japan. A slight increase in risk also occurs in some individuals treated with high-dose radiation therapy for other cancers, such as lymphoma. Tese two changes refect the translocation of chromosome material between chromosomes 9 and 22. A portion of chromosome 9 moves to the end of chromosome 22; in addition, a portion of chromosome 22 moves to the end of chromosome 9. One theory that scientists propose about why this switch occurs is that when the cells are dividing, chromosomes 9 and 22 are very close to each other, making this error more likely. I The process of translocation between the genes on chromosome 9 and chromosome 22. This enzyme triggers signals that cause the stem cell to act in an unregulated (leukemic) manner, leading to the formation of too many white blood cells that live too long. Tose with symptoms often report {{Being very tired or tiring easily {{Shortness of breath during basic, everyday activities {{Unexplained weight loss {{Enlarged spleen or pain or dragging feeling on upper left side of abdomen under the ribs {{Being pale from anemia (a decrease in red blood cells) {{Night sweats {{Inability to tolerate warm temperatures. Tese samples show a {{Specifc pattern of white blood cells {{Small proportion of immature cells (leukemic blast cells and promyelocytes) {{Larger proportion of maturing and fully matured white blood cells (myelocytes and neutrophils). Tese blast cells, promyelocytes and myelocytes are normally not present in the blood of healthy individuals. Tese tests are used to examine marrow cells to fnd abnormalities and are generally done at the same time. For a bone marrow aspiration, a special needle is inserted through the hip bone and into the marrow to remove a liquid sample of cells. For a bone marrow biopsy, a special needle is used to remove a core sample of bone that contains marrow. Both samples are examined under a microscope to look for chromosomal and other cell changes. Samples from the bone marrow are examined to confrm the blood test fndings and to see if there are chromosomal changes or abnormalities, such as the Philadelphia (Ph) chromosome. A small number of patients progress from chronic phase, which can usually be well managed, to accelerated phase or blast crisis phase. Some of these additional chromosome abnormalities are identifable by cytogenetic analysis. In the chronic phase, fewer than 10 percent of the cells in the blood and bone marrow are immature white blood cells (blasts). In this phase, the number of blast cells in the peripheral blood and/or bone marrow is higher than normal. Based on their risk assessment scores, patients are classifed into low-, intermediate or high-risk groups. For more information on the Hasford and Sokal scoring systems, see pages 46 and 50 in the Health Terms section. Some patients may have very high white blood cell counts at the time of diagnosis. This can create viscosity (thickness and stickiness of blood) problems and impair blood fow to the brain, lungs, eyes and other sites and also cause damage in small blood vessels. Treatment {{Usually returns the blood cell counts to normal values within one month and maintains them either at or close to normal levels (slightly lower levels in blood cell counts are not uncommon) {{Reduces the size of the spleen quickly until it approaches its normal size {{Helps prevent infections and abnormal bleeding {{Allows patients to resume their previous levels of day-to-day activities. Patients will need to receive periodic health checks, including blood cell counts and other tests to determine the extent and stability of cytogenetic and molecular remission (see Measuring Treatment Response on page 26). Individuals also need to have their tolerance to drugs assessed from time to time and may need dosage adjustments. Tese drugs are {{Imatinib mesylate (Gleevec) {{Dasatinib (Sprycel) {{Nilotinib (Tasigna). If the frst treatment does not work because of either intolerance or resistance to the therapy, a second treatment option is tried. If both the initial treatment and the subsequent treatment (second-line) fail to work, a third treatment option (third-line treatment) is ofered to the patient. The drug is generally well tolerated by the majority of both younger and older patients, although most people experience some side efects. When Gleevec is not a treatment option, doctors decide, along with their patients, which of the other treatments will be the best alternative. People being treated with Sprycel or Tasigna should note that it is important to follow the specifc instructions for taking these drugs, as these may difer from instructions for Gleevec, which is typically taken with a meal once daily. Identifying the type of mutation responsible for resistance can help a doctor decide which drug to prescribe. When this happens, Sprycel, Tasigna, Bosulif and Iclusig can be alternative treatments. For instance, patients with Gleevec-resistant mutations V299 and F317 are not likely to respond to Sprycel or Bosulif and should be treated with Tasigna or Iclusig instead. Similarly, patients with Gleevec-resistant mutations G250, Y253, E255 and F359 are not likely to respond to Tasigna and should be treated with Sprycel, Bosulif or Iclusig. Interferon alfa (Roferon-A, Intron-A) Pegylated interferon alfa Hydroxyurea (Hydrea) Cytarabine (Cytosar-U) Busulfan (Myleran) Table 1. If patients are experiencing any side efects, they should let members of their healthcare team know right away because they will be able to provide necessary help. Common side efects from Gleevec may include {{Fluid retention (edema) {{Pufness around the eyes {{Nausea and vomiting {{Muscle cramps {{Diarrhea {{Rash {{Chronic fatigue {{Possible cardiac efects (see page 22 for more information). However, it is possible that normal cells are also afected, which may cause these and other side efects. A rare but potential late efect of Gleevec therapy is the loss of the mineral phosphorus from bone which may lead to osteoporosis. In a one-to-one comparison with Gleevec, most side efects were reported less commonly in patients treated with Sprycel. Common side efects from Sprycel may include {{Low white blood cell and platelet counts {{A collection of fuid around the lungs (pleural efusion) page 20 I 800. In a one-to-one comparison with Gleevec, most side efects were reported less commonly in patients treated with Tasigna. For more information about the side efects of Gleevec, Sprycel or Tasigna, speak to your doctor and see the full prescribing information for these medications. Common side efects of Bosulif and Iclusig can be easily prevented or managed with appropriate supportive medication. They may include {{Diarrhea {{Nausea {{Vomiting {{Severe liver toxicity {{Serious vascular events, such as arterial thrombosis. Patients with a history of cardiac disease need to be monitored carefully and frequently. It is unusual, but some patients who were treated with Gleevec, Sprycel and/or Tasigna have developed serious side efects such as {{Severe congestive heart failure (a weakness of the heart that leads to a buildup of fuid in the lungs and surrounding body tissues) {{Left ventricular dysfunction (difculty emptying blood from the left lower chamber of the heart). Your doctor will give you a list of medications to avoid, and will monitor you for these conditions, as needed, before and during treatment. The most common side efects include {{Low red and white blood cell counts page 22 I 800. Side efects can include {{Flulike symptoms such as fever, muscle aches and weakness {{Prolonged fatigue and weight loss, which may require a reduction in dosage {{Hair loss {{Diarrhea {{Depression {{Ulceration of the lining of the mouth {{Cardiac efects {{Other side efects that occasionally occur. Prior to these therapy options, allogeneic stem cell transplantation was the principal means of successful treatment for patients of an appropriate age, in generally good health and with an available donor. Tese patients are counseled by their doctors to weigh the benefts and risks of having an allogeneic stem cell transplant while they are still in remission after their initial Gleevec treatment and particularly after second-line treatment with Sprycel. This approach increases the likelihood of successful remission after transplantation, assuming that drug side efects are minimal. Although transplants are typically more successful in younger patients, there is no specifc age cutof for stem cell transplantation. For information on other treatment options that are either being researched or are in clinical trials, please see page 36. In general terms, the greater the response to drug therapy, the longer the disease will be controlled. Longer-term safety data have also been reported for Sprycel (approved in 2006) and Tasigna (approved in 2007) in patients with Gleevec resistance or intolerance. In addition, the fndings from the ongoing, careful monitoring for long-term or late efects is reassuring so far.
