Mediastinal lymphadenopathyNumber needed to treat: The number needed to treat (NNT) is an epidemiological measure used in communicating the effectiveness of a health-care intervention, typically a treatment with medication. The NNT is the average number of patients who need to be treated to prevent one additional bad outcome (e.Primary mediastinal B-cell lymphoma: Primary mediastinal B-cell lymphoma, abbreviated PMBL, is a type of lymphoma that rises in the mediastinum and predominantly affects young adults.Erasmus Darwin Hudson, Jr.: Erasmus Darwin Hudson (10 November 1843, Northampton, Massachusetts - 9 May 1887, New York City) was a United States physician.Dermatopathic lymphadenopathyTuberculous lymphadenitisHemothoraxTargeted therapy of lung cancer: Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.EdelfosineEndobronchial valve: An endobronchial valve is an implantable medical deviceā€”a small, one-way valve, which is implanted in an airway in the pulmonary system to treat one of several lung conditions. The one-way endobronchial valve is typically implanted such that when a patient exhales, air is able to flow through the valve and out of the lung compartment that is fed by that airway, but when the patient inhales, the valve closes and blocks air from entering that lung compartment.Inferior mesenteric lymph nodes: The inferior mesenteric lymph nodes consist of:Lymphovascular invasionResuscitative thoracotomy: A resuscitative thoracotomy (sometimes referred to as an emergency department thoracotomy or, colloquially, as "cracking the chest") is a thoracotomy typically done in order to resuscitate a person who has been severely injured after sustaining a severe trauma involving the thoracic cavity. For most persons with thoracic trauma the procedure is not necessary; only 15% of those with thoracic injury require the procedure.Breast biopsyDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Video-assisted thoracoscopic surgery: Video-assisted thoracoscopic surgery (VATS) is a type of thoracic surgery performed using a small video camera that is introduced into the patient's chest via a scope. The surgeon is able to view the instruments that are being used along with the anatomy on which the surgeon is operating.PemetrexedFine-needle aspiration: Fine-needle aspiration biopsy (FNAB, FNA or NAB), or fine-needle aspiration cytology (FNAC), is a diagnostic procedure used to investigate superficial (just under the skin) lumps or masses. In this technique, a thin, hollow needle is inserted into the mass for sampling of cells that, after being stained, will be examined under a microscope.ABCD rating: ABCD rating, also called the Jewett staging system or the Whitmore-Jewett staging system, is a staging system for prostate cancer that uses the letters A, B, C, and D.Lung cancer surgery: Lung cancer surgery describes the use of surgical operations in the treatment of lung cancer. It involves the surgical excision of cancer tissue from the lung.
