title: [Partial nephrectomy for cancer and percutaneous biopsy: Oncologic results].
abstract: OBJECTIVE
  To evaluate the results of partial nephrectomy (NP) for cancer in 60 patients selected by the biopsy of the tumor by analyzing the information, oncologic follow-up.
  
  
  METHODS
  It was a cohort study unicenter retrospective from 1994 to 2006. The biopsy was systematically done for patients who were candidates for elective NP. The criteria for elective indications NP tumors were less than 4cm, low grade Fuhrman (I and II). The tubulopapillary tumors (TBP) on biopsy were excluded from the elective indications. The parameters studied were the biopsy data, overall survival, disease-free survival.
  
  
  RESULTS
  The median age was 59 years (32-79 years) and 69% of tumor were fortuitous discovery. Indications of need accounted for 30% of cases (single kidney, bilateral tumors and chronic renal failure [CRF]). Biopsy allowed a diagnosis in 89% of cases. There was one death in specific postoperative immediately. A final histology was 75% of clear cell carcinoma, 13.3% of chromophobe and 11.7% of TBP, 96.6% of T1a including 86.6% of low grade and no surgical margin. The median follow-up was 49 months with 98.5% of specific survival at 5 years, one local recurrence and no general recurrence.
  
  
  CONCLUSIONS
  The study has shown that the selection of patients by biopsy gives satisfactory carcinologic results with 98.5% specific survival at the end of follow-up; it is between 89 and 100% in the literature.
