[The incidence of adenocarcinoma among lung cancers is increasing].

Lung carcinoma represents the first cause of mortality by cancer in men of all industrialized countries. Distribution of lung carcinoma cases in function of histological type is variable from a region to another. Especially in the United States and Western Europe, there is a remarkable decrease in the incidence of squamous cell and small cell carcinoma, simultaneously with a significant increase in the incidence of adenocarcinoma. A comparative study in Strasbourg and Iasi demonstrates that the main histological type of lung cancer still remains squamous cell carcinoma. But in Strasbourg, adenocarcinoma has an important percentage, being found on the first place in women's mortality by cancer. It's likely that in the near future, lung adenocarcinoma will become the predominant histological type in France.
