Although this field is still in its infancy, there are many examples of the successful application of biologic therapy to the treatment of human cancers. The immune system evolved as a means to detect and eliminate molecules or pathogens that are recognized as "nonself" but not to react to host (self) tissues. Many immunotherapies attempted to cause the tumor to appear more "foreign" compared with normal tissues or tried to magnify relatively weak host immune reactions to growing tumors. The immune system differs from most other organ systems because its cells are not in constant contact with each other. They circulate freely throughout the body in and out of the circulatory and lymphatic systems. Immune reactivity involves the integrated action of lymphocytes, monocytes, macrophages, basophils, eosinophils, dendritic cells, endothelial cells, and many other cells throughout the body. Antibodies are a group of proteins composed of one or several units, each of which is composed of two pairs of different polypeptide chains. Each unit possesses two recognition sites, which are capable of combining with the immunizing antigen. The unique bond between antigen and antibody is part of the basis for the exquisite specificity that is the hallmark of immunologic reactivity. The existence of circulating antibodies was first demonstrated in 1890, and until recently, scientific studies of antibodies monopolized the study of immune reactions. Since the 1970s, it has become clear that selected subpopulations of lymphoid cells can secrete a second (nonantibody) class of protein molecules.
Radiation-induced genes represent predominantly cellular signaling molecules blood pressure medication gain weight cardizem 60 mg on line, particularly those induced by transactivation by p53 arrhythmia generator buy cardizem 120mg online. The same factors are also an integral part of the normal process of immunologic rearrangement (Labhart 1999) pulse pressure response to exercise cheap 120 mg cardizem amex. A homologous sequence may be the other allele on a chromosome of a recently replicated sister-chromatid sequence on a daughter chromatid or a similar sequence in a repetitive region along the same chromosome blood pressure 44 order cardizem with american express. In the latter case the sequences may not be identical over long regions, and the mechanism is known as "homeologous" recombination. Recombination between alleles on separate chromosomes occurs at much lower frequency than between identical sequences on sister chromatids or arranged in tandem on the same chromosome. Cells generally exhibit either hRad51 foci or hMre11/hRad50/Nbs foci, but not both, and the choice of which of the mutually exclusive pathways an irradiated cell follows may be determined by Brca1 (Parvin 2001). Dashed arrows and question marks represent possible signaling steps; solid arrows represent reported phosphorylation events. Thus, there are no transcription control or mammalian counterparts of soxR, ada, and lex. This situation presumably reflects the much greater constancy of cellular environment in complex multicellular organisms. Many reports have appeared about adaptive responses involving increased resistance or hypersensitivity in mammalian cells in response to single or multiple doses of ionizing radiation (adaptive effects). There are also reports that the effects of radiation on single cells can influence the response of adjacent nonirradiated cells (bystander effect). These reports are discussed specifically in Chapter 2, but this chapter describes the general stress response and signal transduction pathways that are known to occur after exposure to radiation. The repair will, at the least, result in loss of one of the regions of microhomology. Irradiated cells also generate extracellular signals that resemble cytokines released during normal in vivo cell-cell communication processes (Herrlich and others 1992). These can, through receptors on adjacent cells or gap junctions, result in activation of the signal transduction pathways in nearby cells. These multiple intracellular and extracellular pathways of protein modification and signal transduction may constitute the mechanisms by which many of the transient alterations in cellular metabolism occur after exposure to ionizing radiation (Blattner and others 1994). Some responses observed in particular regimes of exposure to ionizing radiation and given unique names. These apparently distinct radiation responses have been described mainly in cell biology experiments, and in no case do they have solid biochemical support or mechanistic understanding. In addition to controversy among laboratories, some of the responses described appear to be valid only within a limited dose range and under particular experimental conditions. It is also unclear whether different types of cells, such as epithelial cells, fibroblasts, and lymphoid cells, respond similarly or differently in this regard. Some of the inducible responses appear to be complex in that they depend on participation of intercellular gap junctions in communicating radiation responses to neighboring cells. Work on this subject is in the preliminary, descriptive stage, and there is no understanding of what compounds or factors would be transferred between cells in the gap junction. Therefore, it is difficult to evaluate whether the phenomena are of any general physiologic significance. Recent microarray analysis has shown that these changes can involve hundreds of genes and that different stresses can invoke both a common set of genes and genes that are peculiar to particular kinds of stress (Amundson and others 1999a, 1999b). Central to most damage responses is stabilization of the tumor-suppressor gene p53, which occurs as a result of posttranslational phosphorylation or acetylation of the protein (Blattner and others 1999; Figure 1-11).
Bullous edema within the bladder causes high-signal-intensity thickening along the superficial internal surface of the bladder blood pressure medication prices quality cardizem 180mg, a finding that may mimic tumor involvement (63) arrhythmia alliance generic cardizem 120 mg with mastercard. In patients with endometrial and cervical cancer arrhythmia cause order cardizem visa, the presence of lymph node metastases confers a poor prognosis and adversely affects survival (80 peripheral neuropathy order cardizem 180mg without prescription,81). Therefore, identification of involved pelvic and paraaortic lymph nodes alters the therapeutic approach. As our knowledge Lymph Node Evaluation and understanding of tumor biology improve, staging systems must also improve in order to identify significant prognostic factors, which will inform treatment decisions. Ultimately, it provides high-quality data, including response to treatment, survival, and mortality. Thus, it is important that radiologists familiarize themselves with the revised staging classification of endometrial and cervical carcinoma and understand their relevance to disease management.
