14 - Urological Malignancy Flashcards
How common in renal cancer?
3% of all cancers
3 in 10,000
What are the RF for renal cancer?
Obesity
Smoking
DM
Asbestos / Cadmium / Lead
FHx
Von Hippel-Lindau gene (tumour suppressor gene)
What are the protective factors for renal cancer?
Moderate alcohol
Exercise
Which is the commonest renal cancer?
Clear Cell RCC - 75%
Chromophobe RCC
Type I Papillary
How does renal cancer present?
Mass
Haematuria
Pain
Systemic effects
What paraneoplastic effects can occur from renal cancer?
Malaise
Weight loss
Hypercalcaemia
Polycythaemia
Liver dysfunction
What investigations can you do for renal cancer?
Bloods
USS
CT
MRI
Biopsy
What do kidney cancer bone mets look like? How does this differ to prostate bone mets?
Kidney = Lytic lesions
Prostate = sclerotic lesions
Kidney mets - dont show up well on a bone scan
Prostate mets - show up well on a bone scan
At what stage kidney cancer is the tumour no longer limited to the kidney?
Stage III
What is the difference between active surveillance and watchful waiting?
Active surveillance - have found a problem and monitor it before trying to cure it.
Watchful waiting - aim is not to cure - wait for it to cause Sx and then treat the Sx in a palliative approach.
What are the Rx options for renal cancer?
Radical nephrectomy
Partial nephrectomy
Ablation
Immunotherapy
Tyrosine Kinase Inhibitor therapy
Resection of mets
Most cancers = surgery + radio + chemo. However radiotherapy doesn’t work on the kidney and chemo isn’t great either. There surgery + immunotherapy is the best choice.
I.e. Surgery + Immunotherapy + TKIs
What is the peak age of incidence of kidney cancer?
85-89
What is the prognosis for kidney cancer?
95% 5 year survival
Where does transitional cell carcinoma arise from the in the bladder?
From the urothelium
What percentage of TCC of bladder and ureter will be muscle invasive and what percentage will not?
20% will be muscle invasive
80% will not
What percentage of TCC is found in the bladder and what percentage is in the ureter?
95% is bladder
5% is ureter
What are the risk factors for urothelial cancer?
Smoking
Petrochemicals
Hairdressers
Chronic bladder inflammation
Schistosomiasis (more SCC - lays eggs in the bladder)
What are the types of urothelial cancer?
TCC
SCC - 3%
Adenocarcinoma - 1%
What are the S&Sx of urothelial cancer?
Haematuria - 90%
Irritative LUTS
Pain with obstruction
Pelvic mass
What is the prognosis for urothelial cancer?
95% have 5 year survival if not muscle invasive
If muscle invasive - only 5% will be alive at 5 years
What investigations are done for urothelial cancer?
CT Urogram
Cytology
Flexible cystoscopy
Can do CT chest & Bone scan if worried about mets
What are the Rx options for urothelial cancer?
TURBT
Chemo
Radio
Cystectomy
What is painless haematuria assumed to be?
Assumed to be TCC unless proven otherwise
What does TURBT stand for?
Trans-uretheral Resection of Bladder Tumour
What intravesicle medication can be given to Ps with TCC?
Intravesicle BCG - thought to directly infect and kill cancer cells + has immunotherapy effect.
What was found to have an 8% improvement in 5YS for TCC?
Neoadjuvant chemotherapy
Treatment given as a first step to shrink a tumor before the main treatment, which is usually surgery, is given.
How are Ps with metastatic renal cancer treated?
Supportive care
Chemo
Palliative radiotherapy if needed
