Urological Cancers Flashcards
What are the risk factors for prostate cancer?
Increasing age
Family history
Genetic conditions (BRCA2 mutation)
Black-African ethnicity
Tall stature
Anabolic steroids
What are the presenting features of prostate cancer?
Typically asymptomatic
Nocturia, frequency, urgency, hesitancy
Bone pain, cauda equina (advanced disease / mets)
Weight loss
Less common: haematuria, ED
What are some common causes of raised PSA?
Prostate cancer
Benign prostate hyperplasia
Prostatitis / urinary infection
Vigorous exercise (inc cycling)
Recent ejaculation
What are the examinations and investigations for suspected prostate cancer?
DRE
PSA
Multiparametric MRI prostate (first-line investigation)
Biopsy: transrectal ultrasound scan (TRUS) / transperineal biopsy
What score is used to assess a multiparametric MRI of the prostate in suspected cancer?
Likert score
1 - very low suspicion
2 - low suspicion
3 - equivocal
4 - probable cancer
5 - definite cancer
What grading score is used to assess prostate biopsies?
Gleeson score (1-normal to 5-most abnormal)
What criteria must be met for a prostate biopsy to be undertaken?
Multiparameter MRI Likert score of 3 or more
What are the management options for localised prostate cancer?
Curative:
- Active surveillance
- Radical prostatectomy
- Radiotherapy (external beam / brachytherapy)
Palliative:
Deferred hormones (+watchful waiting)
What are the management options for metastatic prostate cancer?
Surgical castration (BL orchidopexy)
Medical castration (hormone therapy) e.g. LHRH agonist (bicalutamide) or GnRH agonists (goserelin)
Palliation: single dose RT, zoledronic acid
How should LHRH agonists be used to treat metastatic prostate cancer?
First 28 days: in combination with anti-androgen (prevent testosterone flare and exacerbation of spinal mets > compression)
If resistance occurs: add in anti-androgen (= combined androgen blockade)
What are the potential side effects of hormone therapy for the management of prostate cancer?
Gynaecomastia
Hot flushes
Osteoporosis
Fatigue
Sexual dysfunction
What is the purpose of zoledronic acid in palliative management of prostate cancer?
Combats tumour-induced hypercalcaemia (TIH) and pain from bone mets
What are the potential side effects of radical prostatectomy?
ED
UI
Which area of the prostate is prostate cancer most likely to develop?
Peripheral zone (75%)
What are the risk factors and epidemiological factors associated with bladder cancer?
M:F 3:1
White ethnicity
Smoking
Occupational exposure (arylamines, polyaromatic hydrocarbons)
