Se utiliza estadística descriptiva, t de Student, test exacto de Fisher y Chi-Square. p<0.05 se aceptó como significativo(AU)

ABSTRACT

OBJECTIVES: To investigate changes in the epidemiology and clinical profile of patients diagnosed with renal clear cell carcinoma in a community health area over 12 years. METHODS: Retrospective analysis of epidemiological characteristics and clinical profile of patients diagnosed with renal clear cell carcinoma in a health area composed of a population of 353.619 inhabitants from January 1999 to December 2010. Descriptive statistical and multivariate analysis, Fisher exact test and Chi-Square were utilized. p<0.05 was accepted as significant. RESULTS: 349 diagnoses of renal mass were reported; 165 of them were clear renal cell carcinoma. Median age was 70.41 years, and the Female/Male rate was 28% and 72%, respectively. 4% women and 30% men smoked ≥20cigarettes/day, more frequently during the period 1999-2001. 52% women and 30% men had hypertension. Hematuria was the most frequent symptom (23%), more frequent in the period 2007-2010, followed by abdominal pain (16%) and renal colic (13%). Weight loss (12%) was more frequent between 1999-2000. Asthenia appeared as the first symptom in 8% of cases. The tumor was incidentally diagnosed in 20% of cases, more frequently in the period between 2007-2010.Diagnosis was established in the Urology Department in 36% of the cases. Stages T1-2 N0 were more frequent between 2007-2010, and M1 between 1999-2000. G3 was more frequent in the entire series. The relative cancer specific mortality of patients who were surgically treated was less in the last 2 years of the period(AU)
