1、Neoplasms of Genitourinary System 泌尿系肿瘤,Adenocarcinoma of the Kidney,（ Renal Cell Carcinoma, RCC, 肾细胞癌）,RCC,In US(1999), 30,000 new cases diagnosed, 11,900 deaths from this disease RCC accounts for 3% of adult cancers, 85% of all primary malignant renal tumors RCC occurs most commonly in 5th6th deca
2、de, male-female ratio 2:1,Etiology,Cause: unknown Risk Factors: cigarette smoking, exposure to asbestos （石棉）and tanning（鞣革）products,Etiology,RCC occurs in 2 forms: -inherited（遗传）：chromosome translocation, Von Hippel-Lindau disease -sporadic（散发）,Pathology,RCC originates from the proximal renal tubula
3、r epithelium. Types: Clear cell type Granular cell type Mixed cell type RCC is most often a mixed adenocarcinoma（腺癌）.,Tumor Staging (Robson System),I: Tumor is confined within the kidney parenchyma. II: Tumor involves the perinephric fat but confined within Gerotas fascia (including the adrenal). II
4、IA: Tumor involves the main renal vein/inferior vena cava.,Tumor Staging (Robson System),IIIB: Tumor involves regional LN. IIIC: Tumor involves both local vessels and LN. IVA: Tumor involves adjacent organs other than the adrenal. IVB: Distant metastases.,Clinical Findings,Symptoms & Signs A. Classi
