Cancers bronchiques : la radiothérapie prophylactique des aires ganglionnaires a-t-elle encore une place ?

摘要: The use of conformal radiotherapy in lung cancer has considerably evolved with the advent improved staging technologies and methods radiation delivery. Patients limited disease, inoperable for medical reasons, may be treated alone; patients more advanced disease are combined chemo-radiotherapy. If local control by dose escalation according to several studies, toxicity particularly pulmonary seems related volume. Thus elective nodal irradiation is being questioned. Data early stage (stage I) non-small-cell or stereotactic hypofractionated strongly supports smaller fields that do not incorporate regions; survival rates approach those surgical series. In locally non-small cell cancer, eliminating allows maximize tumor minimize normal tissue modality treatments; results encouraging. modalities such as positron emission tomography eventually oesophageal ultrasonography increasing, allowing encompass volume accuracy. Several studies have confirmed involved-field into a regional rate less than 10%. Further larger-scale would needed definitely establish "no irradiation" standard cancer. There very few data concerning small
