Treatment of Prostate Cancer had better Survival Rate

PSA blood Test
This study shows
that early treatment of prostate cancer with radiation therapy or
surgery may prolong survival rates compared to patients that are just
observed to see if it gets worse before treating. The study looked at
the data of 48,000 men between the ages of 65 and 80 that had survived
for at least one year after being diagnosed with localized prostate
cancer from 1991 through 1999. Yu-Ning Wong, M.D., an oncologist from
the Fox Chase Cancer Center, presented the results of this study at the
2006 Prostate Cancer Symposium February 25th, in San
Early diagnosis of
prostate cancer can be diagnosed with a PSA (prostate-specific-antigen)
blood test. This blood test can detect very early stages of prostate
cancer that are usually watched and not necessarily treated. It is
possible that the early prostate cancer may not be life threatening and
may grow slowly.
cancers grow so slowly that they never become life-threatening,
especially in elderly men who may die of other causes before the cancer
causes problems," explained Wong. "But other men develop complications
and die from their cancer making the decision to treat quite difficult."
Even though early
treatment of prostate cancer had more success rates, the researchers do
not know if it is beneficial for everyone because of the risks of the
diagnostic procedures and cancer treatment. The complications involved
with the treatment process may be risky and life threatening in itself.
In the research of
these 48,000 men, there were a total of 34,046 who were treated early.
There were 19,948 men that had radiation therapy treatment. There
14,098 were treated with surgery with a radical prostatectomy which is
the removal of the prostate. The remaining 14,560 men were observed for
any changes in the prostate.
At the end the
study, the data reflected that more than half of the men that were
treated were alive with a median survival rate of 13 years. The
observation group that did not get early treatment had a median survival
rate of around 10 years.
population-based study demonstrates a survival advantage for men treated
with either radical prostatectomy or radiation therapy compared to
observation," Wong said. "Eligible men should be considered for both
