[A method of epidural chemical denervation in the combined treatment of a chronic pain syndrome].

The efficacy of epidural chemical denervation used for the treatment of chronic pain syndrome in cancer patients (clinical stage IV) has been studied at different phases of antinociceptive therapy and also in combination with analgesics.
