Lymph node is a rounded mass of lymphatic tissue that is surrounded by a capsule of connective tissue. Lymph nodes filter lymph (lymphatic fluid), and they store lymphocytes (white blood cells). They are located along lymphatic vessels. Also called lymph gland. Regional is in oncology, describes the body area right around a tumor. Lymph is the clear fluid that travels through the lymphatic system and carries cells that help fight infections and other diseases. Also called lymphatic fluid. 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. Regional lymph node is in oncology, a lymph node that drains lymph from the region around a tumor.
Preview- It would appear that, in the 7th edition of AJCC gastric cancer staging, pathologic assessment of the regional lymph nodes entails their removal and histologic examination to evaluate the total number of nodes, as well as the number that contain TDs, and TDs in the fat adjacent to a gastric regional LNM without evidence of residual lymph node tissue were considered as LNM [12]. In the light of these considerations, the aim of the present study is to investigate the possibility of counting TDs as metastatic lymph nodes in TNM classification when LNM and TDs exist simultaneously and to indentify its prognostic value for colorectal cancer patients. Staging, performing exams and tests to learn the extent of the cancer within the body, especially whether the disease has spread from the original site to other parts of the body. It is important to know the stage of the disease in order to plan the best treatment. Colorectal, having to do with the colon or the rectum. Gastric cancer, cancer that forms in tissues lining the stomach. Also called stomach cancer. Metastatic, having to do with metastasis, which is the spread of cancer from the primary site (place where it started) to other places in the body. Tissue is a group or layer of cells that work together to perform a specific function. Histologic examination is the examination of tissue specimens under a microscope. Gastric, having to do with the stomach. Colorectal cancer, cancer that develops in the colon (the longest part of the large intestine) and/or the rectum (the last several inches of the large intestine before the anus). Assessment is in healthcare, a process used to learn about a patient`s condition. This may include a complete medical history, medical tests, a physical exam, a test of learning skills, tests to find out if the patient is able to carry out the tasks of daily living, a mental health evaluation, and a review of social support and community resources
