Peripheral zone
What test could be used to screen for prostate cancer
Prostate Specific Antigen
Not very specific though - can be raised by BPH or infection etc
Prostate cancer is the most common cancer affecting men in the UK - true or false
True
How does prostate cancer present
usually asymptomatic - picked up by PSA Lower UT symptoms Haematuria Bone pain Weight loss Hard prostate
How do you biopsy the prostate
Trans-Rectal USS guided biopsy
Take 5 samples from either side of the prostate

Multifocal adenocarcinoma
Where are the most common sites of metastasis for prostate cancer
Pelvic lymph nodes
Bone
How do you grade prostate cancer
Gleason score
Take the two most abundant cell patterns, score them each and add together to get final score

N+ and M+
How do you manage organ confined prostate cancer
Watchful waiting If not advanced
Radical surgery
Radical radiotherapy
How do you treat locally advanced prostate cancer
Radiotherapy with adjuvant hormone therapy
Watch and wait if asymptomatic
Hormone therapy alone if unit for radio
How do you manage metastatic prostate cancer

Oncocytoma
What is a angiomyolipoma
Benign tumour affecting the blood vessels, smooth muscle and fat
Seen in middle aged women
Which condition is angiomyolipoma associated with
tuberous sclerosis
How does angiomyolipoma present
Loin pain
Haematuria
Mass
Some may have a massive retroperitoneal bleed
How do you diagnose and treat angiomyolipoma
USS and CT
Treat if larger than 4cm with embolization or partial nephrectomy
Describe an oncocytoma a
Benign kidney tumour - doesn’t metastasize
Spherical, brown and has a central scar
Cells are packed with mitochondria

Haematuria Loin pain Mass Pyrexia Varicocele - varicose veins around testicle
What investigations would you do for renal cell carcinoma
USS
CT of chest, abdomen, pelvis - look for mets
FBC and liver/renal functions
List some risk factors for renal cell carcinoma

Renal cell carcinoma
Transitional cell carcinoma
Lymphoma
Describe the epidemiology of testicular cancer
Most common solid cancer in men 20-45
Affects white Caucasians
Most curable cancer
What are some of the risk factors for testicular cancer

Non-seminomatous
How does testicular cancer present
Scrotal lump - hard, irregular
Delayed presentation - acute pain, bleeding, weight loss, neck lumps, chest or bone symptoms
What investigations would you do for testicular cancer
Serum tumour markers - alpha feto protein, B-HCG, LDH
FBC, LFT, renal function
USS testicle
CT chest and abdomen for staging
How do you treat urinary incontinence
Radical inguinal orchidectomy (remove testicle through inguinal region)
Offer sperm preservation
Re-check tumour markers 1-week post-op
CT scan
Follow up with oncology (given adjuvant chemo)

Circumcision may have protective effect
Which part of the penis is most common
The glans
Then the prepuce (foreskin)
How does penis cancer present
Hard painless lump
Lots of delayed presentation though - urinary retention or groin mass
What investigations would you do for penile cancer
Examination of abdo, inguinal and genitalia
MRI scan
CT abdo, pelvis, chest
How do you treat penile cancer affecting the prepuce
Circumcision
Remove affected inguinal nodes
How do you treat penile cancer affecting the glans
Glans resurfacing or resection (depending on depth)
If disease is advanced you may need penile amputation
