Proyecto ADAPTA: Adecuación del tratamiento en dolor irruptivo oncológico

Although there is a broad consensus for the administration of transmucosal fentanyl for BTCP in Spain, there is uncertainty as to the way oncologists adjust their prescription to the patient and what are the determinants of the choice of different pharmaceutical forms. Objectives: The main objective of this study was to analyze and prioritize the attributes that Spanish oncologists consider when assessing treatment options with transmucosal fentanyl in patients with BTCP. Methods: A Scientific Committee performed a classification of 14 relevant attributes in the prescription of transmucosal fentanyl for BTCP. Subsequently, a dossier of scientific evidence was generated comparing these 14 attributes among the different available transmucosal fentanyl formulations, which was shared with the panel of experts (115 Medical Oncologists). After a thorough review of the document, the participants carried out an online vote for the prioritization of the attributes. Results: Out of fourteen attributes analyzed, seven achieved a consensus of ≥ 50 % of the participants: the start of the analgesic action (84 %), the adequacy of the effect of fentanyl to the BTCP episode (72 %), the ease of use (58 %), the presence of mucositis (57 %), the ease of titration of the optimal dose (57%), and the variety of presentations and doses available (59 %). Conclusions: The most valued attributes were those related to the speed of action of the analgesic treatment and its adaptation to the BTCP profile, something to be expected given the spontaneous, unpredictable, and transitory nature of BTCP. As less valued attributes appear the risk of abuse or aberrant behavior and the presence of rhinitis for its administration, which indicates that the existence of these factors do not influence the choice of treatment for BTCP. These results will allow medical oncologists to know what attributes should be taken into account when customizing the patient's treatment of BTCP in order to improve the adequacy of rescue analgesia.
