Adenocarcinoma of the kidney

Adenocarcinoma of the Kidney

( Renal Cell Carcinoma, RCC, 肾细胞癌)

Neoplasms of genitourinary system


  • 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 5th~6th decade, male-female ratio 2:1



  • Cause: unknown

  • Risk Factors:

  • cigarette smoking,

  • exposure to asbestos (石棉)and tanning(鞣革)products



  • RCC occurs in 2 forms:

  • --inherited(遗传):chromosome translocation, Von Hippel-Lindau disease

  • --sporadic(散发)



  • RCC originates from the proximal renal tubular epithelium.

  • Types:

  • Clear cell type

  • Granular cell type

  • Mixed cell type

  • RCC is most often a mixed adenocarcinoma(腺癌).

Tumor staging robson system

Tumor Staging (Robson System)

  • I: Tumor is confined within the kidney parenchyma.

  • II: Tumor involves the perinephric fat but confined within Gerota’s fascia (including the adrenal).

  • IIIA: Tumor involves the main renal vein/inferior vena cava.

Tumor staging robson system1

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

Clinical Findings

  • Symptoms & Signs

  • A. Classical triad——gross hematuria, flank pain, palpable mass (only in 10~15% advanced cases)

  • Symptoms secondary to metastatic disease: dysnea & cough, seizure & headache, bone pain

  • Renal tumors are increasingly detected incidentally by CT or ultrasound

Clinical findings1

Clinical Findings

  • B. Paraneoplastic Syndromes:

  • erythrocytosis(红细胞增多症), hypercalcemia(高钙血症), hypertension

  • C. Lab Findings:

  • anemia, hematuria(60%), ESR↑,

Clinical findings2

Clinical Findings

  • D. X-ray Findings:

  • *Ultrasonography

  • *Intravenous Urography (IVU): 75% accurate (used alone), calcification

  • *CT scanning: more sensitive, mass +renal hilum, perinephric space and vena cava, adrenals, regional LN and adjacent organs

  • *Renal Angiography

Differential diagnosis

Differential Diagnosis

  • Benign renal tumors:

  • Angiomyolipoma (血管平滑肌脂肪瘤, 错构瘤)



  • 1. Localized disease:

  • Surgical removal---only potentially curative therapy

  • Radical Nephrectomy (en bloc removal of the kidney and Gerota’s fascia including ipsilateral adrenal, proximal ½ ureter, regional lymphadenectomy (淋巴结清扫)



  • 2.Disseminated disease:

  • nephrectomy--- reducing tumor burden

  • radiation--- radioresistant tumor, metastases 2/3 effective

  • chemotherapy--- <10% effective

  • immunotherapy--- IL-2/interferon-alpha, 30% response rate



  • Stage 5-year survival rate

  • I 88~100%

  • II 60%

  • III 15~20%

  • IV 0~20%

Renal pelvic cancer

Renal Pelvic Cancer


Neoplasms of genitourinary system

  • Incidence: rare, 3% of all urothelial cancers

  • Pathology:

  • transitional cell 90%

  • squamous cell 10%

Clinical findings3

Clinical Findings

  • A. Symptoms & Signs

  • gross hematuria 70~90%

  • flank pain 8~50%

  • B. Lab Findings:

  • hematuria, cytology (40% positive), tumor markers (BTA, NMP22)

Clinical findings4

Clinical Findings

  • C. Imaging

  • IVU---intraluminal filling defect, unilateral nonvisualization of the collecting system, hydronephrosis

  • US, CT & MRI

  • Ureteropyeloscopy (肾盂输尿管镜)

  • Standard therapy---nephroureterectomy (肾输尿管全长切除)

  • removal of the entire distal ureter with a small cuff of bladder

Bladder carcinoma

Bladder Carcinoma


Bladder ca

Bladder Ca

  • The second most common cancer of the genitourinary system, male-female ratio 2.7:1

  • Initiators/Promoters:

  • cigarette smoking

  • occupational exposure

  • genetic events

Staging tnm system

Staging: TNM System



  • Transitional cell carcinoma(移行细胞癌)90%

  • Nontransitional cell carcinoma: adenocarcinoma, squamous cell Ca, undifferentiated Ca

Clinical findings5

Clinical Findings

  • A. Symptoms:

  • hematuria 85~90%

  • irritative voiding symptoms

  • B. Signs:

  • Majority of patients have no pertinent physical signs.

Clinical findings6

Clinical Findings

  • C. Lab tests:

  • urine test——hematuria

  • urinary cytology——depend on grade and volume of the tumor

  • other markers: BTA, NMP22, telomerase(端粒酶)

Clinical findings7

Clinical Findings

  • D. Imaging:

  • Ultrasonography—screen

  • IVU—evaluation of upper urinary tract

  • CT/MRI—assessment of the depth of infiltration and pelvic LN enlargement

  • E. Cystoscopy(膀胱镜)
