- cancer aerodigestive tract
Aerodigestive tract is the combined organs and tissues of the respiratory tract and the upper part of the digestive tract (including the lips, mouth, tongue, nose, throat, vocal cords, and part of the esophagus and windpipe). 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.
Preview- For instance, INTRODUCTION The habit of drinking mate, or chimarro , as this drink is also called, by hot infusion, made of cut and dry leaves of Ilex paraguariensis, has been indicated as a possible cause of cancer in the aerodigestive tract in South America, where high incidence rates are noticed in an area that includes the south of Brazil, Uruguay and the northeast of Argentina. Such habit is frequent in areas with higher incidence of esophagus cancer and it is not frequent in other areas with lower incidence (1). Infusion is a method of putting fluids, including drugs, into the bloodstream. Also called intravenous infusion. Esophagus is the muscular tube through which food passes from the throat to the stomach. Incidence is the number of new cases of a disease diagnosed each year.
- It`s possible to deduce that, PURPOSE This phase II trial is studying the side effects and how well photodynamic therapy with porfimer sodium works in treating patients with precancerous lesions, cancer, or other disease of the aerodigestive tract. Photodynamic therapy, treatment with drugs that become active when exposed to light. These activated drugs may kill cancer cells. Porfimer sodium is a drug used to treat some types of cancer. When absorbed by cancer cells and exposed to light, porfimer sodium becomes active and kills the cancer cells. It is a type of photodynamic therapy agent. Also called Photofrin. Therapy, treatment. Precancerous is a term used to describe a condition that may (or is likely to) become cancer. Also called premalignant. Phase II trial is a study to test whether a new treatment has an anticancer effect (for example, whether it shrinks a tumor or improves blood test results) and whether it works against a certain type of cancer. Sodium is a mineral needed by the body to keep body fluids in balance. Sodium is found in table salt and in many processed foods. Too much sodium can cause the body to retain water.
- It`s possible to assume that, I don`t know what the options are, but it appears that cancers of the upper Esophagus are sometimes Squamous Cell Cancers and placed in the category of Upper Aero-digestive Tract Tumors. Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Squamous cell, flat cell that looks like a fish scale under a microscope. These cells cover inside and outside surfaces of the body. They are found in the tissues that form the surface of the skin, the lining of the hollow organs of the body (such as the bladder, kidney, and uterus), and the passages of the respiratory and digestive tracts.
