Pie chart showing incidence of large-cell lung cancer (shown in green at upper left) as compared to other lung cancer types, with fractions of smokers versus non-smokers shown for each type. [ 7 ] In most series, LCLC's comprise between 3%-9% of all primary lung cancers .
The main types of lung cancer are non-small cell lung carcinoma and small cell lung carcinoma, the two being distinguished histologically as well as by how they are treated; non-small cell lung carcinoma is primarily treated with surgery if feasible, while small cell lung carcinoma is more frequently treated with chemotherapy and radiation.
There are two main types of lung cancer, categorized by the size and appearance of the malignant cells seen by a histopathologist under a microscope: small cell lung cancer (SCLC; 15% of cases) and non-small-cell lung cancer (NSCLC; 85% of cases). [18] SCLC tumors are often found near the center of the lungs, in the major airways. [19]
For clinical and treatment purposes, however, most oncologists tend to classify lung carcinomas into two major groups, namely small cell carcinoma (SCLC) and non-small cell lung cancer (NSCLC). This is done because of differing responses to treatment—NSCLC is comparatively less sensitive to chemotherapy and/or radiation, so surgery is the ...
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.
Basaloid forms of lung carcinoma were first described in the peer-reviewed medical literature by Dr. Elisabeth Brambilla and her colleagues in 1992. [11] They were first recognized as distinct clinicopathological variants of both squamous cell and large cell lung cancers in 1999, within the third revision of the World Health Organization lung tumor typing and classification scheme.
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.
Lung cancers are now considered a large and extremely heterogeneous family of neoplasms [4] that feature widely varying genetic, biological, and clinical characteristics. . About 50 different lung cancer variants are recognized under the 2004 revision of the World Health Organization ("WHO-2004") histological typing system, the most widely recognized and used lung cancer classification sche
