- cancer unresected
Unresected, describes an organ, tissue, or cancer that has not been either partly or completely removed by surgery. 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- It`s apparent that, evidence suggests that we can, and likely should, treat some lung cancer patients more aggressively to save lives Only half of Stage II or IIIA resected non-small cell lung cancer patients (those who have had surgery to remove the tumour), and less than a third of unresectable (inoperable) Stage IIIA and IIIB patients. 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. Unresectable, unable to be removed with surgery. Surgery is a procedure to remove or repair a part of the body or to find out whether disease is present. An operation. Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Inoperable, describes a condition that cannot be treated by surgery. Stage is the extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body. 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. 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. Lung, one of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body.
- You can determine, percentage of non-small cell lung cancer patients with unresectable (inoperable) disease treated with guideline-recommended combined chemotherapy and radiation Chemotherapy, treatment with drugs that kill cancer cells. 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).
- It really is obvious that, the size of the primary tumor is an important prognostic factor and should be carefully evaluated in choosing optimal therapy.[1] Survival and local control are better with unilateral rather than bilateral parametrial involvement.[2] Patients who are surgically staged as part of a clinical trial and are found to have small volume para-aortic nodal disease and controllable pelvic disease may be cured with pelvic and para-aortic radiation therapy.[3] If postoperative external-beam radiation therapy (EBRT) is planned following surgery, extraperitoneal lymph node sampling is associated with fewer radiation-induced complications than a transperitoneal approach.[4] The resection of macroscopically involved pelvic nodes may improve rates of local control with postoperative radiation therapy.[5] Treatment (Tx) of patients with unresected periaortic nodes with extended-field radiation therapy leads to long-term disease control in those patients with low volume (<2 cm) nodal disease below L3.[6] A single study (RTOG-7920) showed a survival advantage in patients who received radiation therapy to para-aortic nodes without histologic evidence of disease.[7] Toxic effects are greater with para-aortic radiation than with pelvic radiation alone but were mostly confined to
patients with prior abdominopelvic surgery.[7] Patients who underwent extraperitoneal lymph node sampling had fewer bowel complications than those who had transperitoneal lymph node sampling.[4,6,8] External-beam radiation therapy is a type of radiation therapy that uses a machine to aim high-energy rays at the cancer from outside of the body. Also called external radiation therapy. Bowel is the long, tube-shaped organ in the abdomen that completes the process of digestion. The bowel has two parts, the small bowel and the large bowel. Also called intestine. Toxic, having to do with poison or something harmful to the body. Toxic substances usually cause unwanted side effects. Pelvic, having to do with the pelvis (the lower part of the abdomen located between the hip bones). Primary tumor is the original tumor. Bilateral, affecting both the right and left sides of the body. Radiation therapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiotherapy. Resection, surgery to remove tissue or part or all of an organ. Clinical trial is a type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease. Also called clinical study. 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. Clinical, having to do with the examination and treatment of patients. Unilateral, having to do with one side of the body. 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. Tumor is an abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors may be benign (not cancer), or malignant (cancer). Also called neoplasm. Prognostic factor is a situation or condition, or a characteristic of a patient, that can be used to estimate the chance of recovery from a disease or the chance of the disease recurring (coming back). Postoperative, after surgery.
