PROSTATE BIOPSY

Question 1

The mature prostate is between __ g and remains relatively constant until approximately 50 years of
age, when the gland enlarges in many men; the average prostate volume in a 60- to 70-year-old individual is approximately __ g

Answer 1

20-25

48

Question 2

Prostate gland volume can be used to calculate derivatives
such as the PSA density___

value more suggestive of ca?

Answer 2

PSAD = PSA/ Gland Volume

higher density values (>0.15 ng/mL/cc) are more suggestive of prostate cancer; lower values suggest BPH.

Question 3

Congenital prostatic cystic lesions may arise from either Müllerian (__) or Wolffian (__) structures

Answer 3

Müllerian duct cysts and prostatic utricles

ejaculatory duct and SV cysts

Question 4

Men at elevated risk for having prostate cancer are those older than __ years of age; those who have a __history of prostate cancer and are older than 45 years of age or __; or those with a PSA level greater than 1 ng/ mL at __ years of age and greater than 2 ng/mL at__ years of age

Answer 4

50 years

family

African-American

40

60

Question 5

INITIAL PROSTATE BIOPSY •

Initial diagnosis of prostate cancer based on informed decision making in an asymptomatic patient (4)

Answer 5

Summary: DRE, symptoms,suggestive of mets,detected after TURP

Suspicious digital rectal examination findings/prostate nodule (5%–30% cancer risk)
• To diagnose prostate cancer with symptoms suggestive of prostate cancer
• To diagnose prostate cancer with findings suggestive of metastatic disease (bone lesions and/or adenopathy)
• In the setting of prostate cancer detected on routine transurethral resection of the prostate performed for presumed benign disease
