I review recent work on the Roy-Steiner equations for pion-nucleon scattering. This allows to extract the S- and P-wave phase shifts in the low-energy and subtreshold regions and a precise extraction of the much debated pion-nucleon sigma term. I also discuss these results in view of recent sigma term determination from various lattice QCD collaborations.
