Renal Cell Carcinoma (RCC)
Renal Cell Carcinoma (RCC)
• RCC accounts for 2% to 3% of all adult malignant ,
85% of all primary malignant renal tumors, is the most
lethal of the urologic cancers
• Renal cell carcinoma (RCC) affects 38,000 individuals in
the U.S. yearly, and 11,900 patients die of this disease
• RCC occurs most commonly in 5th~6th decade, malefemale ratio 1.6:1
Renal Cell Carcinoma (RCC)
Etiology
• Majority of RCC occurs sporadically
• Tobacco smoking contributes to 24-30% of RCC cases
- Tobacco results in a 2-fold increased risk
• Occupational exposure to cadmium, asbestos, petroleum
• Obesity
• Chronic phenacetin or aspirin use
• Acquired polycystic kidney disease due to dialysis results
in 30% increase risk
Renal Cell Carcinoma (RCC)
Etiology
• 2-4% of RCC associated with inherited disorder
* Von Hippel-Lindau disease
- familial cancer syndrome of retinal angiomas, CNS
hemangioblastomas, pheochromocytomas and clear cell RCC.
* Hereditary papillary renal cancer
- Multiple, bilateral papillary renal tumors , C-met oncogene
on ch 7
* Birt-Hogg-Duke syndrome
- Fibrofolliculomas, lung cysts, and RCC, Mutation in BHD
gene ch 17p
Renal Cell Carcinoma (RCC)
Pathology
• 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.
Renal Cell Carcinoma (RCC)
Clinical Findings
Symptoms & Signs
Renal tumors are increasingly detected incidentally
by CT or ultrasound
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 Cell Carcinoma (RCC)
Clinical Findings
B. Paraneoplastic Syndromes
• Erythrocytosis, hypercalcemia, hypertension
C. Lab Findings
• anemia, hematuria (60%), ESR↑

Renal Cell Carcinoma (RCC)
Clinical Findings
D. Imaging
• Ultrasonography
• Intravenous Urography (IVU):
• CT scanning: more sensitive, mass+renal
hilum, perinephric space and vena cava,
adrenals, regional LN and adjacent organs
• Renal Angiography
• MRI: to evaluate collecting system and IVC
involvement
Renal Cell Carcinoma (RCC)
Diagnosis
• No screening for the general population
• No bio-marker available
• Radiographic evaluation

Renal Cell Carcinoma (RCC)
A, Magnetic resonance scan of
kidneys without administration of
gadolinium suggests anterior right
renal mass.
B, After intravenous administration
of gadolinium-labeled
diethylenetriaminepentaacetic acid,
MRI shows enhancement of this mass
indicative of malignancy.

Tissue Diagnosis
• Tissue diagnosis obtained from nephrectomy or biopsy
Papillary (chromophilic) renal cell
carcinoma extending into the collecting
system with histological findings

Treatment
A. Localized disease:

and Gerota’s fascia including ipsilateral adrenal,
proximal ureter, regional lymphadenectomy

Treatment
B. Disseminated disease:
• nephrectomy--- reducing tumor burden
• radiation--- radioresistant tumor, metastases 2/3
effective
• chemotherapy--- <10% effective
• immunotherapy--- IL-2/interferon-alpha, 30% response
rate
• molecular therapy---eg. sorafenib
Prognosis
• Stage

Bladder Cancer
Bladder Cancer
The second most common cancer of the
genitourinary system (most common in China)
The male-female is 2.7:1
The peak incidence is in persons from 50-70 years

Etiology


Industrial toxins
Cigarette smoking
Genetic events
Other risk factors
cyclophosphamide, alkylating agents,
radiotherapy of pelvis.

Pathology

Bladder Cancer
Clinical Findings
A. Symptoms:
• Painless Hematuria 85~90%
• Irritative voiding symptoms
B. Signs:
• The majority of patients have no pertinent
physical signs.
Bladder Cancer
Clinical Findings
C. Lab tests:
• Urine test——hematuria
• Urinary cytology——depend on grade and
volume of the tumor
• Other markers: BTA, NMP22, telomerase
Bladder Cancer
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
Bladder Cancer
Diagnosis

Ultrasonography can be used as screening method to
detect bladder tumors and upper urinary tract
obstruction.

both CT and MRI are used to characterize the extent of
bladder wall invasion and detect enlarged pelvic lymph
node.
Bladder Cancer
Diagnosis
 Cystoscopy
the diagnosis of bladder cancer depends on cystoscopy.
cystoscopy can provide good information on the extent of the
tumour.
suspicous areas can be biopsied.

Mostly arise from the
peripheral zone of the
gland

Grading
• the Gleason system is widely used for its best clinical correlation

metastases
