Inversion Lerch Phi

Hi all,
I am wondering if there is exist an inversion
formula for the Lerch transcendent Phi(x,s,a)
similar to the inversion of the polylogarithms.
More precisely, I would like to simplify the
expression
Phi(z,s,a) +/- (-1)^s * Phi(1/z,s,-a) = ???
at least for s=1. The ??? should be an
expression easier to compute than Phi.
