Q

What is the gleason grading system

A

a system that assigns a grade to each of the 2 largest areas of cancer in the tissue samples

values range from 1-5 (b-m)
values are added together to come up with the gleason score
2-4 = low (slow)
5-7 = med
8-10 = high (fast)

Q

define grade 2 gleason grade

A

well differentiated
acini are arranged more loosely
irregular shape
some acini invade neighboring tissue

25
Q

define grade 3 gleason.

A

most common
moderately differentiated
acini varying in size from small to large
many acini invade neghboring tissue

26
Q

define grade 4 gleason

A

poorly differentiated
unable to sepearte acinar units
highly irregular and distorted shapes
progressive invasion of neighboring tissue

27
Q

define grade 5 gleason

A

cancer is undifferentiated
bears no resemblance to normal prostate cells
cells are unable to form acinar units

28
Q

What is the PSA test?

A

a blood test that measures the level of prostate specific antigen, which is a protin that is make by the prostate gland. This protin natually leaks out into the blood stream.

29
Q

What PSA values are we generally concerned with?

A

4-10ng/cu.mm = 22% of biopsies show cancer

> 10ng/cu.mm = 66% of prostate biopsies show cancer

note the “cut off” goes up with age

30
Q

What is a better test than just a PSA test?

A
  1. PSA density test: serum PSA/Prostate volume

Prostate volume from TRUS (transrectal ultasonography)

  1. PSA Velocity test
    greater than .75 ng/ml per yaer increase is considered clinically signigicant
31
Q

does free or bound PSA increase more in BPH?

A

Free

32
Q

does free or bound PSA increase more in Prostate cancer?

A

protein bound

33
Q

What are the 2 surgical procedues to enlarge the urethra in BPH?

A

TURP

TUIP

34
Q

aside from PSA, what other blood test could indicate prostate cancer?

A

Prostate Acid Phosphasate

35
Q

what is cryoablation

A

technique of freezing prostate sections as a therapy

36
Q

What is Nadir

A

the lowest PSA level acieved after prostate cancer treatment – usually 2ng/ml or less is needed to be considered in remission

37
Q

what is brachytherapy?

A

radiotheraphy treatment with ionizing radiation whose source is applied to the surface of the body or is located a short distance from the body area being treated

38
Q

What are the three main stages of cancer development?

A
  1. Initiation (ionizion radiaiont, visruses, enviomental factors, ect)
  2. Promotion (elevated IGF-1 levels, high concumption of animal fats, dietary deficency of protective factors such as vit C, D, E, or essentila fatty acitds
  3. Proliferatoin (prolonged exposute to DHT, estrogesnts, agen orange, xenobiotics, obesity, high insulin resistance
39
Q

What are the suggestions for a natural approch to prostate problems?

A
  1. Chiro
  2. saw palmetto
  3. green tea
  4. zinc
  5. PC-SPES Herbal Formula
  6. Beta-Sitosterol
  7. Pygeum afticanum
  8. get rid of mercury fillings
  9. good water
  10. exercise
  11. avoid xenoestrogent
  12. increase number of ejaculations
