Urologocial cancer Flashcards
Risk factors for prostrate cancer
Increasing age
Family history (4x higher risk if 1st degree relative <60)
BRCA2
Afro-Caribbean>Caucasian>Asian
Presentation of prostate cancer
Asymptomatic LUTS - nocturia, urgency, frequency, hesitancy, straining, post micturation dribble, intermittent/weak stream Bone pain (lower back) Ejaculatory symptoms (very rare) - haematospermia
Diagnosis of prostate cancer
DRE + PSA (need both together!)
MRI pelvis can be performed pre-biopsy to decide if need a biopsy and which biopsy method is more appropriate
Prostate biopsy (transrectal or transperineal)
Describe transrectal and transperineal prostate biopsies
Transrectal: done under LA, 3% risk of sepsis, given high dose antibiotics beforehand (metronidazole and ciprofloxacin)
Transperineal: done under GA, lower infection risk
Causes of raised PSA
Prostate cancer UTI Prostatitis BPH Urinary retention
If patient has a UTI, when should you redo the PSA level
4-6 weeks
Percentage of men with a normal PSA who have prostate cancer
15%
Treatment for metastatic prostate cancer
Surgical:
Orchidectomy
Hormone therapy:
LHRH agonist depot (gasorelin) with initial anti-androgen (bicalutamide) to prevent initial flare up
Add-ons:
Prednisolone
Docetaxel chemo
Palliative management of metastatic prostate cancer
Single dose radiotherapy
Zoledronic acid
Treatment of locally advanced prostate cancer
Radical radiotherapy + adjuvant hormone therapy
Curative management of localised prostate cancer
Active Surveillance - PSA and DRE every 6 months
Radical prostatectomy (only <70)
Radiotherapy
Palliative management of localised prostate cancer
‘Watch and wait’
Can give hormone therapy if progressing
Candidates for robotic prostatectomy
Age <70
Intermediate/high risk localised prostate cancer
PSA <20
BMI <35
Describe length time and lead time bias
Length time bias:
Screening programme is better at picking up slow growing tumours
Lead time bias:
Screening picks up cancer much earlier than it would have been detected clinically and therefore appears to improve survival
Differential for haematuria
Urological cancer Stones UTI Inflammation BPH Glomerular disease
3 key investigations for haematuria
Endoscopy: flexible cystoscopy
Radiology: ultrasound of kidneys and bladder
Urine: cytology
Investigations usually performed by GP before get to urology investigations
EGFR
ACR
MSU
Investigations for painless testicular lump
Refer via 2ww
Urgent USS of scrotum to diagnose
If USS confirms mass - tumour markers
When to suspect penile cancer
Penile lump or ulcer which:
Persists despite treatment
OR
STI has been excluded
