Patient History • John is a 64-year old retired school teacher. • You recently sent him to see his urologist for an assessment. He is quite worried because his recent PSA is 2.5 ng/mL, which is up from the last recorded value 1 year ago at 1.2 ng/mL. • John is now concerned that his mild lower urinary tract symptoms (LUTS) indicate that he has newly developed prostate cancer. His friend was recently diagnosed with prostate cancer. PSA = Prostate-Specific Antigen
John’s Response • John says his urine stream has changed • He now rises to void five times nightly and has moderate urgency during his working day. • His stream is slow but he has never had any episodes of urinary retention.
In Your Practice, How Would You Determine the Severity of John’s Symptoms at this Stage?
IPSS = International Prostate Symptom ScoreAUA = American Urological Association
Discussion • The IPSS and Quality of Life due to Urinary Symptoms Questionnaires are requested of John • You ask him to complete the forms before proceeding • Here are John’s scores: International Prostate Symptom Score (IPSS) Patient name: John DOB: 05/05/41 ID: 0019-0027 Date of assessment: 29/06/05 Initial assessment (X) Monitor: during __X__ therapy after _____therapy/surgery
How Do You Interpret the Severity and Bother of John’s Symptoms?
Interpreting the IPSS and Bother Score • John’s IPSS = 22 (severe symptoms) • John’s Bother Score = 3 (mixed bother) IPSS = International Prostate Symptom Score
Physical Examination DRE = Digital Rectal Examination
What Investigations Might You Consider for John at this Stage of the Consult?
Lab Results Lab tests: Urinalysis: no abnormal findings PSA: 2.5 ng/mL Blood/Glucose: negative Urethral swab: negative PSA = Prostate-Specific Antigen
Management Strategy • John’s mixed bother and high IPSS are indications of a need for further evaluation • Furthermore, his elevated PSA level of 2.5 ng/mL, while not extremely high, warrants referral to a urologist. IPSS = International Prostate Symptom ScorePSA = Prostate-Specific Antigen
Urologist Feedback • John’s prostate size measurement via DRE is critical for monitoring his condition • Measurements (4.2 x 5.2 X 5.5 cm) give a calculated volume of 63 ml and technician observed that the bladder was not completely empty after voiding. DRE = Digital Rectal Examination
Long Term Follow-up • John is placed on combination therapy of a 5α-reductase inhibitor and an α1-blocker • The PSA is expected to decrease by approximately 50% in the first 6-12 months and then not rise appreciably while on 5α-reductase inhibitor. • He is monitored annually via DRE and PSA DRE = Digital Rectal ExaminationPSA = Prostate-Specific Antigen
Long Term Follow-up • Is there anything else the GP should do or discuss with this patient, besides annual monitoring of DRE and PSA? DRE = Digital Rectal ExaminationPSA = Prostate-Specific Antigen
Long Term Follow-up • This 64 year old gentleman with a PSA of 2.5, benign enlarged prostate gland should be reassured that his risk of clinically important prostate cancer is small. • He needs to have continued monitoring. • He is quite symptomatic and treatment with combination therapy has been initiated. • If his PSA starts to rise while on 5α-reductase inhibitor treatment then referral back to urologist is indicated. • He could be told that 5α-reductase inhibitor therapy with finasteride has been shown in a study to reduce the risk of future development of prostate cancer. PSA = Prostate-Specific Antigen
