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.
Five-year survival rate: 10 to 20% ... Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. ... Without treatment, tumors spread ...
Adenocarcinoma of the lung is currently the most common type of lung cancer in "never smokers" (lifelong nonsmokers). [10] Adenocarcinomas account for about 40% of lung cancers. Historically, adenocarcinoma was more often seen peripherally in the lungs than SCLC and squamous-cell lung cancer, both of which tended to be more often centrally located.
[10] [14] Cases have been documented of continued growth of these lesions over a period of 10 years without symptoms or metastasis. [8] The overall mortality rate appears to be somewhere in the vicinity of 18% to 27%, depending on the criteria that are used to define this entity.
It is standardized with the C section of ICD-10. There were no changes in the topography axis between ICD-O-2 and ICD-O-3. See List of ICD-10 codes#(C00–C97) Malignant Neoplasms for examples.
Acinar adenocarcinoma of the lung is a highly lethal disease. Overall, the five-year survival rates approximate 16% to 22%. Generally, survival is better in all stages for patients with the acinar (or papillary) pattern than it is in patients with the solid pattern, but considerably worse than those with the bronchioloalveolar pattern.
Indeed, pancreatic cancer has one of the worst survival rates of all cancers. Small cell lung cancer has a five-year survival rate of 4% according to Cancer Centers of America's Website. [5] The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival ...
Adenocarcinoma in situ (AIS) of the lung —previously included in the category of "bronchioloalveolar carcinoma" (BAC)—is a subtype of lung adenocarcinoma.It tends to arise in the distal bronchioles or alveoli and is defined by a non-invasive growth pattern.
