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.
Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
Lung cancer is the most diagnosed and deadliest cancer worldwide, with 2.2 million cases in 2020 resulting in 1.8 million deaths. [3] 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.
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system .
Small cell lung cancer is often treated as a systematic disease due to its tendency for early dissemination, [4] thus, instead of the traditional TNM staging system, the Veterans' Administration Lung Study Group (VALSG) introduced a simplified 2-stage system in the 1950s to divide small cell lung cancer into limited stage and extensive stage. [7]
Although it is common in the lung cancer literature to refer to histologically mixed tumors containing significant numbers of malignant giant cells as "giant-cell carcinomas", technically a diagnosis of "giant-cell carcinoma" should be limited strictly to neoplasms containing only malignant giant cells (i.e. "pure" giant-cell carcinoma). [1]
Combined small cell lung carcinoma (or c-SCLC) is a form of multiphasic lung cancer that is diagnosed by a pathologist when a malignant tumor, arising from transformed cells originating in lung tissue, contains a component of small cell lung carcinoma (SCLC) mixed with one or more components of any histological variant of non-small cell lung carcinoma (NSCLC) in any relative proportion.
Lung cancer is a large and exceptionally heterogeneous family of malignancies. [4] Over 50 different histological variants are explicitly recognized within the 2004 revision of the World Health Organization (WHO) typing system ("WHO-2004"), currently the most widely used lung cancer classification scheme.
