Tests involved with prostate
cancer treatment:
Digital Rectal Examination (DRE)
Your doctor inserts a gloved finger into the rectum to feel the condition
of the prostate that
lies close to the rectal wall. If your doctor feels something suspicious
such as a lump or bump, further tests will be carried out. Other tests
are needed to enable a more accurate diagnosis.
Prostate Specific Antigen (PSA) Test
A blood sample is taken by your doctor to check for prostate specific
antigen (PSA), which
is produced by the prostate and is increased by cellular abnormalities
within the prostate.
As men get older the prostate gland grows and so the PSA is likely
to rise. A high PSA may indicate some type of prostate disease. The
level can be raised due to inflammation of the prostate (Prostatitis)
and enlargement of the prostate gland (Benign Prostatic Hyperplasia
or BPH).
PSA is a useful tool for diagnosing and monitoring prostate diseases,
but further tests are required to confirm which condition is present.
TRUS Biopsy

Staging and Grading
The tests performed are used to determine the stage of the
prostate cancer. Biopsy specimens are analysed to find out how aggressive
the cancer is.
The staging system describes how far the cancer has spread
within and/or beyond the
prostate capsule.
Stage 1/A:
There are no symptoms and the tumour is confined within the prostate.
It is usually found
during the investigation of a different complaint.
Stage 2/B:
Again the tumour is confined to the prostate and although symptoms
may not be apparent,
it can be felt during a DRE.
Stage 3/C:
The tumour has spread just outside the prostate gland and may effect
nearby tissue.
A common symptom is difficulty in urinating.
Stage 4/D:
Also known as Metastatic cancer, the tumour has spread to other parts
of the body.
Bones and Lymph nodes are commonly afflicted and symptoms may include
fatigue,
weight loss, bone pain and difficulty urinating.
The Gleason Score indicates how aggressive the cancer is. The
Gleason Score (or Sum)
is something that the pathologist tells about the cancer in terms
of its aggressiveness on
the basis of careful inspection under the microscope. The Gleason
Score is actually made
up of 2 numbers known as Gleason Grades. When a pathologist
looks at the prostate
cancer under the microscope, a number grade from 1 to 5 is assigned
to the areas most representative of the cancer present (the primary
Gleason Grade). A second number
grade from 1 to 5 is given to the second most representative area
within the cancer
(The secondary Gleason Grade). These two numbers are added together
to give the
Gleason Score, the maximum Gleason Score is 10 and the minimum Gleason
score is 2.
The higher the score, the more aggressive the tumour is likely to
be and this will impact
on the likely success of treatment.
Bone Scans
Your doctor may want to see if the cancer has metastasised and has
affected you bones.
A small amount of radioactive material is injected into your arm,
which is then absorbed by
your bones as they heal. Your arm will then be scanned an hour later
to view the activity of
the bone and ascertain whether the cancer has spread.
