Local anesthetics are in general not suitable for the treatment of patients with severe cancer pain. Local blocks are useful for diagnostic and prognostic purposes. ⋯ The use of local anesthetics may yield long-lasting relief in some specific pain syndromes, such as tumor-related reflex dystrophies, in painful muscle spasms, and trigger points due to tumor-affected vertebrae. In addition, local anesthetics may have a generally beneficial effect in the restless, cachectic, and aged patient.
