18
Q

What part of BPH does prostate usually impact

A

central periurethral zone of prostate

19
Q

clinical features of BPH dealing with urination

A
  • problems starting and stopping urine stream
  • impaired bladder emptying with increased risk for infection and hydronephrosis
  • dribbling
  • hypertrophy of bladder wall smooth muscle, increased risk for bladder diverticula
  • microscopic hematuria may be present
20
Q

What does BPH show in serum levels

A

prostate-specific antigen (PSA)

21
Q

who makes PSA and what does it do

A

prostate glands

liquefies semen

22
Q

What is used to treat BPH

A

alpha1-antagonist (Terazosin)
alpha1A-antagonist (Tamsulosin)
5alpha-reductase inhibitor

23
Q

MOA action of Terazosin

A
  • relax smooth muscle

- relaxes vascular smooth muscle lowering blood pressure

24
Q

when is Tamsulosin used

A

normotensive individuals to avoid alpha 1B effects on blood vessels

25
Q

MOA for 5alpha-reductase inhibitor

A
  • blocker conversion of testosterone to DHT
26
Q

Side effects of 5alpha-reductase inhibitor

A

gynecomastia and sexual dysfunction

27
Q

what else of 5-alpha reductase used to treat

A

male pattern baldness

28
Q

how long does it take for 5alpha reductase to work

A

months

29
Q

What is the most common cancer in men, and 2nd most common cause of cancer-related death

A

prostate adenocarcinoma

30
Q

what is prostate adenocarcinoma

A

malignant proliferation of prostatic glands

31
Q

what are risk factors for prostate adenocarcinoma

A

age
race ( african american then caucasians then asians)
diet high in saturated fats

32
Q

clinical symptoms of prostate adenocarcinoma

A

often silent

33
Q

where in the prostate does prostate adenocarcinoma usually occur

A

peripheral, posterior region of prostate

34
Q

when does screening begin for prostate adenocarcinoma

A

50 yrs with DRE and PSA

35
Q

correlate normal PSA levels with age

A

increases

36
Q

what type of PSA is suggestive of cancer

A

decreased % free-PSA

cancer makes bound PSA

37
Q

what is required to confirm diagnosis of prostate adenocarcinoma

A

prostatic biopsy

38
Q

histo for prostate adenocarcinoma

A

small, invasive glands with prominent nucleoli

39
Q

what grading system is used for histo for prostate adenocarcinoma? what is it based on

A

Gleason grading system

based on architecture ( not nuclear atypia)

40
Q

how does Gleason grading system work

A
  • multiple regions of tumor assessed
  • score 1-5
  • add score
  • higher score worse prognosis
41
Q

Where does prostate adenocarcinoma spread? what does this result in

A
  • lumbar spine or pelvis common
  • results in osteoblastic metastases that present as low back pain and increased alkaline phosphatase, PSA, and prostatic acid phosphatase (PAP)
42
Q

how is prostate adenocarcinoma treated

A

prostatectomy: localized disease

hormone suppression to reduce testosterone and DHT: advanced disease

43
Q

what hormone suppression drugs are used in prostate adenocarcinoma

A
  • Leuprolide: GnRH analog

- Flutamide: competitive inhibitor at androgen receptor
