title: [Adult renal cancer in Senegal: Current epidemiological, clinical features, profile's evolution over the two past decades].
abstract: OBJECTIVE
  To study current epidemiological and clinical features of adult renal cancer in Senegal and the evolution of these features over the two past decades.
  
  
  METHODS
  We conducted a retrospective ten years study (2000-2009) that analyzed all the renal cell cancer in adult admitted in the urology department and the pathology department of the university teaching hospital Aristide-Le-Dantec (Dakar). The results of this study were compared with those of the previous decade.
  
  
  RESULTS
  We included 74 cases of renal cell cancer. The median age of patients was 49 years (18-72 years). There was a slight female predominance (51.3%). Twenty-eight (37.8%) patients presented at least with one renal cell cancer risk factor. The median duration of symptoms was 10 months (1-96 months). The localization of the renal cancer was right in 42 patients (56.7%) and left in 32 cases (43.8%). Almost all the tumors were symptomatic. Symptoms were dominated by loin pain (87.8%) and abdominal mass (77%). There were only two cases (2.7%) of incidental renal cell cancer. The median tumor size was 12 cm (2.4-26 cm). The more frequent tumor stages according to the TNM 2002 staging system were T2 (39.2%) and T3 (33.7%). Metastases were found in 23 (31%) patients. Forty-four patients underwent nephrectomy (43 radical and one partial). No adjuvant treatment or metastasectomy were done. The main histological subtype of tumors was renal cell carcinoma (47 cases). The mean duration of the follow up was 30.5 ± 33.6 months. Among the 44 patients who underwent nephrectomy, no tumor recurrence was found on 35 cases. Tumor recurrence occurred on nine patients. The specific mortality rate was 47.3%. Epidemiological and clinical features of the adult renal cell cancer in Senegal haven't significantly changed over the 20 past years.
  
  
  CONCLUSIONS
  The adult renal cell cancer incidence was low in Senegal. Its clinical profile was characterized by a predominance of locally advanced and metastatic forms.
