Nodular Lymphocyte Predominant Hodgkin's Lymphoma
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a slow-growing CD20 positive form of Hodgkin lymphoma, a cancer of the immune system's B cells. NLPHL is an uncommon sub-type of Hodgkin lymphoma, making up 5-10% of Hodgkin lymphomas. It is distinguished from classic Hodgkin lymphoma by the presence of CD20 positive lymphocyte predominant cells, also known as popcorn cells due to their polylobated nuclei, which look like popcorn. There are small but clear differences in prognosis between the various forms. Lymphocyte predominant HL is an uncommon subtype composed of vague nodules of numerous reactive lymphocytes admixed with large popcorn-shaped RSC. Unlike classic RSC, the non-classic popcorn-shaped RS cells of NLPHL are CD15 and CD30 negative while positive for the B cell marker CD20. The anti-CD20 monoclonal antibody Rituximab has been used in lymphocyte predominant Hodgkin lymphoma with encouraging results. BCL6 gene rearrangements have been frequently observed. S ...

Micrograph
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BEACOPP
BEACOPP is a chemotherapy regimen for treatment of Hodgkin lymphoma developed by the German Hodgkin Study Group used for patients in Stages > II or early (IA or IB) with unfavorable risk factors. Patients typically receive treatment in cycles of 21 days with no drugs given on days 15–21. There also exists a more intensive regimen with cycles of 14 days. Usually a course of BEACOPP therapy consists of four, sometimes six to eight cycles, or in combination with ABVD. In some countries BEACOPP still is experimental, in others (e.g. Germany and Austria) it is a standard therapy. In the United States, ABVD (or Stanford V) is generally given instead, because BEACOPP is perceived by practicing oncologists to have the potential to induce more secondary neoplasias (such as leukemias). However, the final results from the GHSG HD14 trial indicate that "there were no overall differences in treatment-related mortality or secondary malignancies" of BEACOPP relative to ABVD. Oncologists in the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABVD
ABVD is a chemotherapy regimen used in the first-line treatment of Hodgkin lymphoma, replacing the older MOPP protocol. It consists of concurrent treatment with the chemotherapy drugs: * Adriamycin (also known as doxorubicin/ hydroxydaunorubicin, designated as H in CHOP) * Bleomycin * Vinblastine * Dacarbazine (similar to procarbazine, designated as P in MOPP and in COPP) Medical uses As of 2007, ABVD is widely used as the initial chemotherapy treatment for newly diagnosed Hodgkin lymphoma. It has been the most effective and least toxic chemotherapy regimen available for treating early-stage Hodgkin Lymphoma. The other chemotherapy regimens that are widely used in this setting is the Stanford V and BEACOPP regimens. Administration One cycle of ABVD chemotherapy is typically given over 4 weeks in two doses, with the first on day 1 and the second dose on day 15. All four of the chemotherapy drugs are given intravenously. ABVD chemotherapy is usually given in the outpatient set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthracycline
Anthracyclines are a class of drugs used in cancer chemotherapy that are extracted from ''Streptomyces'' bacterium. These compounds are used to treat many cancers, including leukemias, lymphomas, breast, stomach, uterine, ovarian, bladder cancer, and lung cancers. The first anthracycline discovered was daunorubicin (trade name Daunomycin), which is produced naturally by ''Streptomyces peucetius'', a species of Actinomycetota. Clinically the most important anthracyclines are doxorubicin, daunorubicin, epirubicin and idarubicin. The anthracyclines are among the most effective anticancer treatments ever developed and are effective against more types of cancer than any other class of chemotherapeutic agents. Their main adverse effect is cardiotoxicity, which considerably limits their usefulness. Use of anthracyclines has also been shown to be significantly associated with cycle 1 severe or febrile neutropenia. Other adverse effects include vomiting. The drugs act mainly by interc ...

Monoclonal Antibody Therapy
Monoclonal antibody therapy is a form of immunotherapy that uses monoclonal antibodies (mAbs) to bind monospecifically to certain cells or proteins. The objective is that this treatment will stimulate the patient's immune system to attack those cells. Alternatively, in radioimmunotherapy a radioactive dose localizes a target cell line, delivering lethal chemical doses. Antibodies have been used to bind to molecules involved in T-cell regulation to remove inhibitory pathways that block T-cell responses. This is known as immune checkpoint therapy. It is possible to create a mAb that is specific to almost any extracellular/cell surface target. Research and development is underway to create antibodies for diseases (such as rheumatoid arthritis, multiple sclerosis, Alzheimer's disease, Ebola and different types of cancers). Antibody structure and function Immunoglobulin G (IgG) antibodies are large heterodimeric molecules, approximately 150 kDa and are composed of two kinds of ...

Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can ''tag'' a microbe or an infected cell for attack by other parts of the immune system, or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion). To allow the immune system to recognize millions of different antigens, the antigen-binding sites at both tips of the antibody come in an equally wide variety. In contrast, the remainder of the antibody is relatively constant. It only occurs in a few varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surveillance, Epidemiology, And End Results
The Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute (NCI) is a source of epidemiologic information on the incidence and survival rates of cancer in the United States. The Program SEER collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 34.6% of the population of the United States. SEER coverage includes 30.0% of African Americans, 44% of Hispanics, 49.3% of American Indians and Alaska Natives, 57.5% of Asians, and 68.5% of Hawaiian/Pacific Islanders. The SEER Program registries routinely collect data on patient demographics, primary tumor site, tumor morphology and stage at diagnosis, first course of treatment, and follow-up for vital status. The SEER Program is the only comprehensive source of population-based information in the United States that includes stage of cancer at the time of diagnosis and patient survival data. History SEER began collecting data on cance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Therapy
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue ...

Watchful Waiting
Watchful waiting (also watch and wait or WAW) is an approach to a medical problem in which time is allowed to pass before medical intervention or therapy is used. During this time, repeated testing may be performed. Related terms include ''expectant management'', ''active surveillance'', and ''masterly inactivity''. The term ''masterly inactivity'' is also used in nonmedical contexts. A distinction can be drawn between ''watchful waiting'' and ''medical observation'', but some sources equate the terms. Usually, watchful waiting is an outpatient process and may have a duration of months or years. In contrast, medical observation is usually an inpatient process, often involving frequent or even continuous monitoring and may have a duration of hours or days. Medical uses Often watchful waiting is recommended in situations with a high likelihood of self-resolution if there is high uncertainty concerning the diagnosis, and the risks of intervention or therapy may outweigh the benefit ...

Ann Arbor Staging
Ann Arbor staging is the staging system for lymphomas, both in Hodgkin's lymphoma (formerly designated Hodgkin's disease) and non-Hodgkin lymphoma (abbreviated NHL). It was initially developed for Hodgkin's, but has some use in NHL. It has roughly the same function as TNM staging in solid tumors. The stage depends on both the place where the malignant tissue is located (as located with biopsy, CT scanning, gallium scan and increasingly positron emission tomography) and on systemic symptoms due to the lymphoma ("B symptoms": night sweats, weight loss of >10% or fevers). Principal stages The principal stage is determined by location of the tumor: * ''Stage I'' indicates that the cancer is located in a single region, usually one lymph node and the surrounding area. Stage I often will not have outward symptoms. * ''Stage II'' indicates that the cancer is located in two separate regions, an affected lymph node or lymphatic organ and a second affected area, and that both affected area ...
