Bladder and Renal Cancer Flashcards
Where is the most common site for urothelial cancers?
Bladder (90%)
What is the most common type of bladder cancer?
Transitional Cell carcinoma
If schistosomiasis is the cause of the bladder cancer what is the most common tumour type found?
Squamous cell carcinoma
What are the risk factors for TCC?
Smoking (accounts for 40% of cases)
Aromatic amines
Non-hereditary genetic abnormalities (e.g. TSG incl. p53 and Rb)
What are the risk factors for SCC?
Schistosomiasis (S. haematobium only)
Chronic cystitis (e.g. recurrent UTI, long term catheter, bladder stone)
Cyclophosphamide therapy
Pelvic radiotherapy
What are the presenting features of bladder cancer?
Painless haematuria (micro or frank) Recurrent UTI Storage bladder symptoms Dysuria, frequency, nocturia, urgency +/- urge Incontinence Bladder pain
What are the symptoms of Upper urinary tract TCC?
Frank haematuria Unilateral ureteric obstruction Flank or loin pain Symptoms of nodal or metastatic disease -Bone pain -Hypercalcaemia -Lung -Brain
What investigations should be done in UTT TCC?
CT-IVU or IVU
Urine cytology
Ureteroscopy and biopsy
What are two types of benign renal tumours?
Oncocytoma
Angiomyolipoma
What are the four histological subtypes of renal adenocarcinoma?
Clear cell
Papillary
Chromophobe
Bellini type ductal carcinoma
What are the risk factors for renal carcinoma?
Family history (autosomal dominant e.g. vHL, familial clear cell RCC, hereditary papillary RCC; can be bilateral and/or multifocal) Smoking Anti-hypertensive medication Obesity End-stage renal failure Acquired renal cystic disease
What is the presentation for renal cell carcinoma?
Asymptomatic
‘Classic triad’ of flank pain, mass and haematuria
Paraneoplastic syndrome
Anorexia, cachexia and pyrexia
Hypertension, hypercalcaemia and abnormal LFTs
Anaemia, polycythaemia and raised ESR
Metastatic disease-bone, brain, lungs, liver
What investigations should be done for renal cell carcinoma?
CT scan (triple phase) of abdomen and chest is mandatory
Bloods : U&E, FBC
Ultrasound differentiates tumour from cyst
DMSA or MAG-3 renogram to assess split renal function if doubts about contralateral kidney
What is the treatment for RCC?
Radical nephrectomy
RCC is chemo and radioresistant so need to use Tyrosine kinase inhibitors instead for metastases
