The authors report a series of 60 cases of @entity703 observed over a 10-year period. @entity1 consisted of 35 @entity1 (58%) and 25 @entity1 (42%), with a mean age of 52 years (range: 21-72 years). The clinical features were polymorphic, dominated by loin @entity158 (76%), haematuria (75%), a lumbar mass (46%), alteration of the general state (30%). The diagnosis was established by ultrasonography in 58 @entity1 and CT scan in 38 @entity1 . The mean @entity5 diameter was 11.5 cm (5-25 cm) and two cases presented @entity5 . The @entity5 was located in the upper pole in 40% of cases and was mid-renal in 30% of cases. The time to diagnosis ranged from 2 months to 3 years. Staging reflected the advanced stage of the @entity5 . Treatment was surgical for 53 @entity1 (88%). A lumbar incision was generally performed (83%). The surgical procedure consisted of nephrectomy and regional or hilar lymph node dissection. Nephrectomy was simple for 27% of @entity1 , radical for 69% of @entity1 and partial for 4% of @entity1 . The postoperative course was marked by one death due to @entity1151 , and a stercoral fistula in 2 @entity1 . Histological examination of the specimen showed clear cell @entity420 in 92% of cases. The @entity5 weight was often considerable, with a maximum of 3.750 kg. The lymph nodes removed were invaded in 50% of cases. The mean follow-up was 46 months (12 to 120 months). Follow-up was normal at 3 years for 23 @entity1 (43%) and at 10 years for 4 @entity1 (8%). @entity5 recurrence in the renal compartment was observed in 3 @entity1 after 3 years. Asynchronous metastases occurred in 10 @entity1 (23%). The mean interval to metastases was 20 months (4 to 36 months).
