I am not aware of Stata programs doing Joinpoint regressions. But there
is a program available at http://srab.cancer.gov/joinpoint/. 

Hope this helps

If you are only counting first cancers of a particular type, there is no
correlation between time-intervals.  The count observed within each
time-interval will be an independent realisation of the underlying
Poisson process.

Dear listers,
Has anyone done joinpoint regression for time trends in incidence rates
of cancer in stata? Any other suggestions as to how time trends of
incidence rates in the entire population can be analyzed properly
incorporating correlation between time-intervals?

Regards,
