Lung, one of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body. Lung cancer, cancer that forms in tissues of the lung, usually in the cells lining air passages. The two main types are small cell lung cancer and non-small cell lung cancer. These types are diagnosed based on how the cells look under a microscope. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy. Bone marrow is the soft, sponge-like tissue in the center of most bones. It produces white blood cells, red blood cells, and platelets.
Preview- As an example, patients treated for locally advanced non-small cell lung cancer who receive chemotherapy and proton beam therapy have fewer instances of bone marrow toxicity than patients who receive the standard treatment of intensity-modulated radiation (IMRT) and concurrent chemotherapy, according to researchers from The University of Texas M. Radiation, energy released in the form of particle or electromagnetic waves. Common sources of radiation include radon gas, cosmic rays from outer space, medical x-rays, and energy given off by a radioisotope (unstable form of a chemical element that releases radiation as it breaks down and becomes more stable). Toxicity is the extent to which something is poisonous or harmful. Proton is a small, positively charged particle of matter found in the atoms of all elements. Streams of protons generated by special equipment can be used for radiation treatment. Non-small cell lung cancer is a group of lung cancers that are named for the kinds of cells found in the cancer and how the cells look under a microscope. The three main types of non-small cell lung cancer are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Non-small cell lung cancer is the most common kind of lung cancer. Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Chemotherapy, treatment with drugs that kill cancer cells. Small cell lung cancer is an aggressive (fast-growing) cancer that forms in tissues of the lung and can spread to other parts of the body. The cancer cells look small and oval-shaped when looked at under a microscope. IMRT is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor. Also called intensity-modulated radiation therapy.
- It could seem apparant that, the conventional treatment for locally advanced non-small cell lung cancer is intensity-modulated radiation with concurrent chemotherapy. The majority of lung cancer patients who receive this therapy are at risk of bone marrow toxicity, a debilitating side effect of treatment that further weakens a patient`s already vulnerable immune system. The occurrence of bone marrow toxicity - the reduction of hemoglobin, neutrophils, lymphocytes and white blood cells - results in a patient`s inability to withstand aggressive treatment, rendering it less effective. Immune system is the complex group of organs and cells that defends the body against infections and other diseases. Conventional treatment is a currently accepted and widely used treatment for a certain type of disease, based on the results of past research. Also called conventional therapy. Reduction is a chemical reaction that takes place when a substance comes into contact with hydrogen or another reducing substance. Aggressive is in medicine, describes a tumor or disease that forms, grows, or spreads quickly. It may also describe treatment that is more severe or intense than usual. Blood is a tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes. Hemoglobin is a protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the body and carries carbon dioxide back to the lungs. Testing for the amount of hemoglobin in the blood is usually part of a complete blood cell (CBC) test. It is used to check for conditions such as anemia, dehydration, and malnutrition. Side effect is a problem that occurs when treatment affects healthy tissues or organs. Some common side effects of cancer treatment are fatigue, pain, nausea, vomiting, decreased blood cell counts, hair loss, and mouth sores.
- It`s possible to conclude that, high-dose chemotherapy with peripheral blood progenitor cell support for patients with non-small cell lung cancer the experience of the European Group for Bone Marrow Transplantation (EBMT) Solid Tumours Working Party. Transplantation is a surgical procedure in which tissue or an organ is transferred from one area of a person`s body to another area, or from one person (the donor) to another person (the recipient). High-dose chemotherapy is an intensive drug treatment to kill cancer cells, but that also destroys the bone marrow and can cause other severe side effects. High-dose chemotherapy is usually followed by bone marrow or stem cell transplantation to rebuild the bone marrow. Peripheral blood, blood circulating throughout the body. Bone marrow transplantation is a procedure to replace bone marrow that has been destroyed by treatment with high doses of anticancer drugs or radiation. Transplantation may be autologous (an individual`s own marrow saved before treatment), allogeneic (marrow donated by someone else), or syngeneic (marrow donated by an identical twin).
