The basis of treatment of primary disease in case of metastatic cancer at diagnosis is based on the knowledge of the natural history of the disease, the biology of the primary tumour and its metastases, advances in modern radiotherapy techniques (modulated intensity, stereotactic radiotherapy) in order to improve the survival of patients with advanced disease. The clinical concept of oligometastatic disease at diagnosis has repositioned the interest of local treatment for primitive disease because these patients have a slower evolutionary profile than metastatic disease extended from the outset. This article reviews the indication of radiotherapy as a local treatment for primary cancer in a de novo metastatic diagnosed disease in the case of breast cancer, non-small cell lung cancer and prostate cancer.
