AUA statement

PSA screening in men under age 40 years is not recommended.

Routine screening in men between ages 40 to 54 years at average risk is not
recommended.

For men ages 55 to 69 years, the decision to undergo PSA screening involves
weighing the benefits of preventing prostate cancer mortality in 1 man for every
1,000 men screened over a decade against the known potential harms
associated with screening and treatment. For this reason, shared decisionmaking is recommended for men age 55 to 69 years that are considering PSA
screening, and proceeding based on patients’ values and preferences.

To reduce the harms of screening, a routine screening interval of two years or
more may be preferred over annual screening in those men who have
participated in shared decision-making and decided on screening. As compared
to annual screening, it is expected that screening intervals of two years preserve
the majority of the benefits and reduce over diagnosis and false positives.

Routine PSA screening is not recommended in men over age 70 or any man
with less than a 10-15 year life expectancy.

Scenario 1
• A 55 year old chinese male has come for his routine visit to review his hypertension. He complains of difficulty initiating urination and poor stream occasionally for the past 1 month.
• Medication: nifedipine LA 30mg om and simvastatin 10mg on
• Examination : BP 130/74 no palpable bladder
• PR : prostate smooth normal size
SHP symposium - 13 Jul 2013
• Investigations : UFEME 0 RBC 2 WBC 2 EC
SHP symposium - 13 Jul 2013
How would you manage this patient?
1. Start dutasteride and review in 4 weeks
2. Watchful waiting
3. Refer to our friendly urologist for further management
SHP symposium - 13 Jul 2013
Scenario 2
• A 60 year old man is complaining of poor stream and urinary frequency for the past few months. He has been seen by a urologist a few months ago and is currently on dutasteride. He feels the medicine is not working.
• Examination: no palpable bladder
• PR: smooth, 4.5 finger breadth prostate
SHP symposium - 13 Jul 2013
How would you manage this patient?
1. Add an alpha‐blocker and tell him to monitor for improvement of his symptoms.
2. Switch to an alpha‐blocker and review him in 2 weeks.
3. Advise him to go and see his urologist as he probably requires surgery for his condition.
SHP symposium - 13 Jul 2013
Scenario 3
• A 52 year old obese lawyer comes to you requesting for screening tests for prostate cancer. His colleague was just recently diagnosed with cancer and he is worried. His elder brother has an ‘enlarged prostate’
and his uncle has prostate cancer. He is currently asymptomatic.
SHP symposium - 13 Jul 2013
• PR: smooth, normal sized prostate
SHP symposium - 13 Jul 2013
How would you manage this patient?
1. Explain to him that a PSA test is not recommended as a screening tool for prostate cancer and tell him it is unlikely he has cancer.
2. Refuse to do a PSA test as it is poorly correlated with the probability of cancer. Alternatively, refer him to a urologist for ‘other’ screening tests.
3. Order a PSA test and refer him to the urologist if it is >4ng/ml
