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 5th~6th decade, 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 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) • 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 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. 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 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 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 • Benign renal tumors: • Angiomyolipoma (血管平滑肌脂肪瘤, 错构瘤)
Treatment • 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)
Treatment • 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
Prognosis • Stage 5-year survival rate • I 88~100% • II 60% • III 15~20% • IV 0~20%
Incidence: rare, 3% of all urothelial cancers • Pathology: • transitional cell 90% • squamous cell 10%
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 Findings • C. Imaging • IVU---intraluminal filling defect, unilateral nonvisualization of the collecting system, hydronephrosis • US, CT & MRI • Ureteropyeloscopy (肾盂输尿管镜)
Treatment • Standard therapy---nephroureterectomy (肾输尿管全长切除) • removal of the entire distal ureter with a small cuff of bladder
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
Histopathology(组织病理学) • Transitional cell carcinoma(移行细胞癌)90% • Nontransitional cell carcinoma: adenocarcinoma, squamous cell Ca, undifferentiated Ca
Clinical Findings • A. Symptoms: • hematuria 85~90% • irritative voiding symptoms • B. Signs: • Majority of patients have no pertinent physical signs.
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 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)
Treatment • 1. Surgery • TUR (Trans-Urethral Resection) • Partial Cystectomy (膀胱部分切除) • Radical Cystectomy(根治性膀胱全切除) • 2. Radiotherapy
Treatment • 3. Intravesical Chemotherapy(膀胱内化疗) • molecular response • weight rate • Mitomycin C 329 39~78% • Thiotepa 189 up to 55% • Doxorubicin 580 mean 38% • BCG 36~71%
CaP • The most common cancer in American men • Increases rapidly with age • 95% are adenocarcinoma
Clinical Findings • A. Symptoms • early stage: asymptomatic(无症状) • locally advanced/metastatic disease—obstructive or irritative voiding complaints, bone pain, paresthesias(感觉异常)and weakness of lower extremities • B. Signs: DRE—induration(硬结)
Clinical Findings • C. Tumor markers • PSA(前列腺特异抗原)Prostate Specific Antigen • < 4 ng/ml normal • 4 ~ 20 ng/ml Grey Zone • > 20 ng/ml highly suspect of PCa
Clinical Findings • D. Prostate biopsy(活检) • golden standard • E. Imaging • TRUS, MRI, Bone scan
Treatment • 1. Localized disease • (optimal form in great debating) • Watchful waiting • Radical prostatectomy(根治性前列腺切除) • Radiation—external beam
