[Cancer genetic screening for patient with multiple renal tumors: What is the current practice for what results?]

To evaluate in a high volume center the practice and the performance of cancer genetic screening for patients with multiple renal tumors without a predisposition to kidney tumors known at the time of surgery.

All patients treated for multiple renal tumors from January 2000 to December 2013 in our center were included. Patients with a family history of renal cell carcinoma, a kidney disease or a genetic predisposition to renal cancer known at the time of surgery were excluded from the analysis. Our list of patients was retrospectively compared to the records from PREDIR (PREDisposition to Kidney Tumors) center of Île-de-France, which regionally centralizes the care of patients with kidney tumors associated with a genetic predisposition.

One hundred and thirty-six patients were included. Twenty-six patients of 136 (19%) were referred to PREDIR center: 23 followed the screening and 3 did not show up in consultation. Of the 23 patients screened, three genetic predispositions to kidney tumors were identified (13%). Of the 95 patients with synchronous tumors, 48% with more than 3 tumors benefited from cancer genetics investigation against 13% of those presenting only two tumors.

Our study shows that cancer genetic investigations are not routinely offered to patients with multiple kidney tumors, conversely to existing guidelines. Urologists must be aware of this screening.
