A Pancoast tumor is a tumor of the apex of the lung. It is a type of lung cancer defined primarily by its location situated at the top end of either the right or left lung. It typically spreads to nearby tissues such as the ribs and vertebrae. Most Pancoast tumors are non-small-cell lung cancers. The growing tumor can cause compression of many ...
1.8 million (2020) [3] Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
Limited-stage small cell lung carcinoma. persistent cough, chest pains, rust-coloured sputum, shortness of breath, fatigue, weight loss, wheezing, hoarseness, pneumonia, bronchitis. median overall survival time of approximately 12–16 months, with five-year survival rate of approximately 26% and the long-term survival rate of approximately 4 - 5%.
Oncology. Adenocarcinoma of the lung is the most common type of lung cancer, and like other forms of lung cancer, it is characterized by distinct cellular and molecular features. [1] It is classified as one of several non-small cell lung cancers (NSCLC), to distinguish it from small cell lung cancer which has a different behavior and prognosis.
Non-small-cell lung cancer (NSCLC), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [1][2][3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
Frequency. ~10% of pneumonia cases requiring hospitalization [1] Aspiration pneumonia is a type of lung infection that is due to a relatively large amount of material from the stomach or mouth entering the lungs. [1] Signs and symptoms often include fever and cough of relatively rapid onset. [1]
Treatment of lung cancer. Treatment of lung cancer refers to the use of medical therapies, such as surgery, radiation, chemotherapy, immunotherapy, percutaneous ablation, and palliative care, [1][2][3][4] alone or in combination, in an attempt to cure or lessen the adverse impact of malignant neoplasms originating in lung tissue.
Lung cancer staging is the assessment of the extent to which a lung cancer has spread from its original source. As with most cancers, staging is an important determinant of treatment and prognosis. In general, more advanced stages of cancer are less amenable to treatment and have a worse prognosis. The initial evaluation of non-small cell lung ...
