BACKGROUND. Breakthrough pain is transitory exacerbation of pain that occurs in addition to otherwise stable persistent pain. The wide differences in estimation of incidence reported in literature are probably because of different settings and meanings attributed to the definition of breakthrough pain. METHODS. A panel of experts met to establish the actual knowledge on breakthrough pain, according to the evidence in literature and experience. They agreed that episodic or transient pain could be a more simple and adequate term in most languages, including English, French, Italian, and Spanish. RESULTS. A specific assessment and precise pain characterization are essential to plan the most appropriate treatments. Despite the relevance of this temporal pain pattern for the influence on the outcome and quality of life, few controlled studies have been performed to give evidence of a specific approach. Several experiences have reported the possible efficacy of different drugs, route of administration, and modalities of administration in different circumstances. CONCLUSIONS. Prospective studies with previous treatments using similar terminologies are necessary to find the most convenient therapeutic intervention, according to the temporal pattern characteristics and the pain mechanism involved.
