My wife had a large soft tissue sarcoma last year (successfully
removed!). Memorial Sloan Kettering internet site says that betw 7 and
8,000 Americans are diagnosed thus every year. Indeed, the disease is
SO rare it is almost impossible to study because the numbers are so
small there aren't enough to compose a research group based on current
standards.

My question is: a. what is the incidence (is it 8,000/300,000,00)? b.
And what is the probability for any one American to be diagnosed in a
given year? c. Can you show the simple way such a probability is
figured?

doug_stearns,

Please let me know via the "CLARIFICATION" feature if this is the type
of information you're looking for?

Incidence (annual) of Soft Tissue Sarcoma: 8,300 annual cases (SEER
2002 estimate) Incidence Rate for Soft Tissue Sarcoma: approx 1 in
32,771 or 0.00% or 8,300 people in USA

bobbie,

thanks ... clarification follows:

if the odds of winning the lottery are 16 million to one, what are the
odds of contracting a soft tissue sarcoma? do you have all the info
you need to calc that?

Dear Doug Stearns,

Please let me know if any of the following material helps.




A cancer incidence rate is the number of new cancers of a specific
site/type occurring in a specified population during a year, usually
expressed as the number of cancers per 100,000 population at risk.
That is,

Incidence rate = (New cancers / Population) × 100,000 

The numerator of the incidence rate is the number of new cancers; the
denominator is the size of the population.

US Cancer Statistics, 2002 Incidence & Mortality provides the most
comprehensive federal data available to date on state-specific cancer
incidence rates.

In November 2005, the Department of Health and Human Services released
US Cancer Statistics: 2002 Incidence and Mortality, the most
comprehensive federal report available on state-specific cancer rates.
This report contains official federal government cancer statistics for
more than 1 million invasive cancer cases diagnosed during 2002 among
residents of 44 states, 6 metropolitan areas, and the District of
Columbia, and these geographic areas are inhabited by about 93% of the
U.S. population. The race and ethnicity categories have been expanded
this year to include national cancer incidence and mortality data for
American Indians/Alaska Natives.The report supplies essential state,
population, racial, ethnic and gender information for tailored cancer
prevention and control programs nationwide.

Are the incidence rates in the above table satisfactory?

Clarification of Question by doug_stearns-ga on 02 Feb 2006 14:10 PST

bobbie,

thanks ... what i'm wondering how to calculate the odds of being
diagnosed with soft tissue sarcoma ... it is exactly equivalent to
figuring the odds of hitting the correct lottery number but starting
with different numbers ...

however the info and links you've already sent have been very helpful ...

i wondered if you have a one in a million chance greater or lesser??

Hello again Doug,

The chances are less than one in a million.

Please go to this URL 
http://wrongdiagnosis.com/lists/incid.htm

Scroll down  to view condition number 235
Condition :     Soft Tissue Sarcoma 
Percent:        0.00%
Rate:           1 in 32,771 
US People:      8,300 
Data :          8,300 annual cases (SEER 2002 estimate) 

Now scroll down to conditions 316 to 320
The rates for these medical conditions are 1 in 1 million
