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 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
Which is the commonest cancer in men?
Prostate cancer
Where is the commonest and lowest incidence of prostate cancer?
Highest = Australia, USA, Western Europe
Lowest = Japan, Eastern Asia
What are the S&S of prostate cancer?
Asymptomatic in early stages
Haematuria
LUTS
Haematospermia
Bone pain if mets
Bladder outflow obstruction with AKI - rare
How is prostate cancer diagnosed?
Elevated PSA
DRE
Prostate biopsy
What is the 5YS rate of prostate cancer?
98%
Which grading system is used for prostate cancer?
Gleason grading system
What is PSA?
Enzyme involved in the liquification of semen - should be found in high levels in the semen and should be low in the blood
What do you look for on a DRE for prostate cancer?
Size
Induration
Asymmetry
Loss of median sulcus
Nodule
When should Ps with prostate cancer have a bone scan?
If their PSA >20 or Gleason score >4
Which is the best imaging for metastatic disease?
PET-CT - picks up v low grade metastatic disease
What can PSA be increased by apart from cancer?
BPH
Infection
Instrumentation
Ejactularion
Retention
Which medications can lower PSA?
Finasteride
Dutasteride
What happens to our PSA as we age naturally?
The prostate grows with age - therefore PSA should naturally increase incrementally with age.
How is prostate density linked to cancer risk?
Increased prostate density = inc risk of prostate cancer
What is doubling time?
How long it takes for the PSA to double - can be a good predictor of when Rx will be needed
Where does prostate cancer like to metastasise to?
Pelvis
Axial skeleton
Ribs
What is brachytherapy?
Internal radiation treatment - surgery puts seeds of radiation into the prostate = can use a higher dose and it decays over weeks
How is hormone therapy used with prostate cancer?
Can you androgen deprivation therapy = stops the prostate from gdowing
Can also use synthetic LHRH agonists (this causes a rise and then a fall by negative feedback mechanism in testosterone release) b- commonest!
Can use LHRH antagonist
Can also use antiandrogens (Biclutamide) which block the effect of testosterone directly
What is RALP?
Radio-assisted Laparotic Prostatectomy
How does prostate treatment differ with age?
Younger Ps = more surgery, brachytherapy, radio and chemo
Older Ps - no surgery or brachytherapy or chemo. More hormones & radiotherapy
