Prostate Cancer Flashcards
What are risk factors for prostate cancer
Increasing age
Obesity
Afro-Caribbean
Famile history
What are clinical features of prostate cancer?
Asymptomatic - cancers tend to develop in peripheral prostate so don’t cause obstructive symptoms early
Bladder outlet obstruction: Hesitancy, urinary retention Poor stream Terminal dribbline Haematuria Haematospermia Pain: back, perineal, testicular
Weight loss and bone pain suggests mets
DRE: asymmetrical, hard, nodular enlargement with loss of median sulcus craggy
How is prostate cancer diagnosed?
PSA measurement
DRE
Trans-rectal USS guided biopsy
MRI/CT for staging
What is histology of prostate cancer?
Adenocarcinoma of the peripheral zone
How is prostate cancer staged?
MRI/CT
TNM
What can raise the PSA?
BPH
Prostatitis and UTI
Ejaculation (ideally not in previous 48h)
Vigorous exercise (ideally not in previous 48h)
Urinary retention
Instrumentation of urinary tract
How localised prostate cancer managed?
Conservative: active surveillance (regular PSA) and watchful waiting (wait for symptoms)
Radical prostatectomy
Radiotherapy: external beam and brachytherapy
How is localised advanced prostate cancer managed?
Hormonal therapy:
GnRH agonist - Goserelin
Anti-androgen - cyproterone acetate prevents DHT binding from intracytoplasmic protein complexes
Radical prostatectomy
Radiotherapy
How is metastatic prostate cancer managed?
Horomnal therapy
Anti-androgen cyproterone aceteate
Orchidectomy
How is prostate cancer prognosis assessed? How does it spread
Gleason grading system
2 grades awarded for most dominant grade (1-5) and second most dominant grade (1-5) and added
Lymphatic spread first to obturator nodes and local extra prostatic spread to the seminal vesicles
What advice should be given to asymptomatic man asking for PSA test?
Test is not very accurate
If test is falsely positive - may needlessly have more tests
Only one in three of those with high PSA may have cancer
Worried needlessly if alter tests are clear
IF cancer found, no way to tell if it will impinge on health
Treatment may cause more bad effects
Who should be referred for 2WW assessment?
Men aged 50-69 should be referred if PSA is >= 3 or there is abnormal DRE
