Lung cancer is rare in those younger than 40; the average age at diagnosis is 70 years, and the average age at death 72. [2] Incidence and outcomes vary widely across the world, depending on patterns of tobacco use. Prior to the advent of cigarette smoking in the 20th century, lung cancer was a rare disease.
Many small series have suggested that the prognosis of lung tumors with giant cells is worse than that of most other forms of non-small-cell lung cancer (NSCLC), [11] including squamous cell carcinoma, [42] and spindle cell carcinoma. [42] The overall five-year survival rate in GCCL varies between studies but is generally considered to be very low.
It is an uncommon low-grade malignant lung mass that is most often in the central airways of the lung. It is also known as "atypical lung carcinoid tumour", " atypical lung carcinoid" or "moderately differentiated neuroendocrine carcinoma". It is a more aggressive than typical carcinoid tumors: nodal metastases in 70% vs. 5%.

Lung cancer is an extremely heterogeneous family of malignant neoplasms, [5] with well over 50 different histological variants recognized under the 4th revision of the World Health Organization (WHO) typing system ("WHO-2004"), [2] currently the most widely used lung cancer classification scheme. Because these variants have differing genetic ...
This small solitary tumor exhibits pure alveolar distribution (lepidic growth) and lacks any invasion of the surrounding normal lung. If completely removed by surgery, the prognosis is excellent with up to 100% 5-year survival. [1]
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
