Prostate & Testes Flashcards
MC nondermatological malignancy in males
Prostate cancer (adenocarcinoma)
MCC of cancer-related death in males
- Lung
- Prostate
Typical location/zone of prostate that cancer develops
Peripheral zones
RFs for prostate cancer
- Age - Most important (31-40) < (81-90)
- Prostatitis
- FHx of prostate cancer
- High fat diet
Sxs of Prostate cancer
- Asymptomatic (early bc of peripheral location)
- Urinary retention
- Weak urine flow
- Frequency
- Hesitancy
MC site of prostate cancer metastasis
Bone (Vertebrae) –> Pain & Fractures
Tx of non-metastatic prostate cancer
- External beam radiation
- Brachytherapy (radioactive seed implants)
Tx of extensive prostate cancer
Radical Prostatectomy - retropubic, perineal, laparoscopic or robotic
MC complications of radical prostatectomy
Impotence & Incontinence
Tx of metastatic prostate cancer
- GnRH agonist - Leuprolide
- Androgen receptor antagonist- Flutamide, Bicalutamide
- Chemotherapy (not very effective)
Tx of prostate cancer in older men
Observation - slow growing
Monitoring Prostate treatment
PSA
Screening for Prostate cancer
- PSA - large or acute change
- DRE - asymmetrical, nodular, indurated
- Abnormal –> Biopsy (ALWAYS) - Alkaline phosphatase- elevated when the cancer has invaded
- Controversy — Case based — 40-50 years — PSA & DRE
Definite diagnosis of prostate cancer
Needle core biopsy guided by transrectal ultrasound
- CT for extent & treatment
RFs for BPH
Increasing age (>50)
MC location of BPH
Peri-urethral/ transition zone –> Obstruction
Sxs of BPH
- Hesitancy
- Weak urine stream
- Frequency
- Urgency
- Dysuria
- Nocturia
Relation of BPH & Prostate cancer
BPH doesnt predispose to cancer
Diagnostic workup of BPH
- History
- Physical
- DRE - uniform, enlarged, rubbery - Mild PSA elevation
Complications of untreated BPH from urinary obstruction
- B/l hydronephrosis
- Bladder diverticula & smooth muscle hypertrophy
- Infection - urine stasis
- Infarction - painful, enlarged, firm gland w. increased PSA
Tx of BPH
Behavior modification
1. Avoid liquids before bed
2. dec. caffeine & alcohol
3. Double voiding to completely empty bladder
Medication
1 Mild- moderate –> Alpha blocker (Tamsulosin, terazosin)
2. Severe –> alpha blocker + 5-alpha-reductase inhibitor (Finasteride)
Tx of Refractory BPH
TURP (Transurethral Resection of the Prostate)
or
Transurethral needle ablation (cant undergo surgery)
