The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
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.
This is a shortened version of the second chapter of the ICD-9: Neoplasms. It covers ICD codes 140 to 239. The full chapter can be found on pages 101 to 144 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
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.

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.
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.
Unlike extensive-stage small cell lung cancer, limited-stage small cell lung cancer is potentially curable. [4] In limited small cell lung cancer, the median overall survival time is approximately 12–16 months, with five year survival rate of approximately 26% and long-term survival rate of approximately 4–5%. [19]
Small cell mesothelioma – an extremely rare subtype of lung cancer – can be mistaken for small cell lung cancer. [10] Small-cell carcinoma is most often more rapidly and widely metastatic than non-small-cell lung carcinoma [11] (and hence staged differently). There is usually early involvement of the hilar and mediastinal lymph nodes. [12]
