[Bellini tumours].

In Europe, renal tumours are 7th in frequency of men cancers. They are rare tumours in 10 to 15% of cases. Collecting ducts carcinomas or Bellini tumours, described for the first time in 1949, are a distinct clinical and pathological entity. They represented 1% of epithelial cancers. Nephrectomy is the treatment of localised cancer. Because of lack of recommendations, usually in clinical practice, treatment is similar to urothelial carcinomas treatments (gemcitabine plus platinium). A 72% of response rate of urothelial carcinoma to association of bevacizumab with platinium and gemcitabine 1st line chemotherapy in metastatic setting was reported. More, cases of responses of metastatic Bellini cancers to antiangiogenic treatments associated to chemotherapy were reported these last years. Bellini cancers have a poor prognostic. Unless the fact that this cancer is aggressive, after nephrectomy, cancer specific survival seems not to be different to those of patients with clear cells renal carcinoma and could be related to latest stage of disease in patients. The evaluation of efficacy of association of bevacizumab to chemotherapy is still going on in this association.
