Cancer du poumon : « Les » radiothérapies

Lung cancer is situated among the most frequent cancers in France and represents the first cause of death by cancer on a national scale. Lung cancer represents a major problem of public health, seen its frequency and its remaining poor outcome. Most of patients benefit from a multidisciplinary treatment. The radiotherapy is combined most of the time with the surgery and the chemotherapy or the targeted therapies. The recent advances in radiotherapy with the development of stereotactic radiation therapy or intensity modulated radiation therapy allowed an evolution in the treatment of the lung cancer with changes in term of objectives of treatment. The most representative example of this evolution of techniques is represented by the management of lung tumors less than 5 cms and without involved nodes. For these tumors, the stereotactic radiation therapy allows to obtain rates of local control equivalent to the surgery and widely superior to those obtained with the 3D conformational radiotherapy.
