Bladder cancer
Renal cell carcinoma
ADENOCARCINOMA OF THE KIDNEY
ADENOCARCINOMA OF THE KIDNEY (RENAL CELL CARCINOMA) 1. Location: parenchyma of kidney 2. Histological types: Origin from renal tubule cells Most are clear cell carcinoma
RENAL CELL CARCINOMA
3. Passages of metastasis: Direct extension: renal vein Blood metastasis: brain, bone, liver, lung Lymphatic metastasis: lymph node of kidney
Symptoms 50~ 60 years old, male/female is 2/1 Three major symptoms: 1. Hematuria: invade pelvis 2. Mass: tumor large enough 3. Pains: dull pain
Symptoms
Diagnosis 1. Symptoms: Hematuria, mass, pains 2. IVP: Calices and pevis are compressed and distortion 3. CT and B ultrasound: Mass in parenchyma
IVP
CT
Treatment 1. Radical nephrectomy: kidney, fascia, fat and lymph nodes around kidney 2. Embolization of kidney: before operation, make it easy to be resected
Treatment
Tumor of renal pelvis ❂ Transitional cell carcinoma:
most common ❂ Squamous cell carcinoma:
Cause: irritation of stone infection
Tumor of renal pelvis
Symptoms and diagnosis 1. 40~70 years of age, male/female ratio is 2:1 2. symptom: intermittent painless gross hematuria 3. IVP: filling defect of pelvis
IVP
Symptoms and diagnosis 4. Cystoscopy: bleeding from ureteral orifice 5. Urine cytology: cancer cells 6. B ultrasound and CT:
CT
Treatment Operation: Resection extent : Kidney, Ureter and Partial bladder wall around ureteral orifice
Treatment
Bladder cancer
Bladder cancer ❂ The most common tumor of urinary
system ❂ Histology:
Transitional cell carcinoma
Bladder cancer ❂ Differentiation:
Grade I: low malignancy Grade II: middle malignancy Grade III: high malignancy
Bladder cancer Growth modes: Carcinoma in situ Papillocarcinoma Invasive carcinoma Location: lateral wall and back wall
Growth modes
Clinical stages of bladder cancer
Symptoms ❂ 50~70 years of age,
male/ female is 4:1
❂ Hematuria:
intermittent, painless
❂ Late stage:
difficult urination, urgency,
retention of urine
Diagnosis ❂ History and symptoms ❂ cystoscopy: ❂ IVP:
mass
filling defect of bladder; if there is tumor in ureter and pevis
❂ CT and ultrasound
Cystoscopy
Cystoscopy
CT
Treatment Operations: 1. Transurethral resection of bladder tumor: ( TUR-BT ) 2. partial cystectomy: at lest 2 cm around tumor
3. Total cystectomy
TUR-BT
Chemotherapy: Instillation of bladder Drugs: BCG thiotepa Mitomycin Pirarubicin
