Background Neuropathic pain is a prevalent symptom in patients with cancer, which needs a more specific algorithm than nociceptive pain or neuropathic pain from other origin. Clinical practice guidelines ( CPGs) can be helpful in optimizing the diagnosis of neuropathic pain in patients with cancer. Methods In this study, 9 national CPGs in Europe on the diagnosis of neuropathic pain in patients with cancer were included. Recommendations with their grade (according SIGN 55 classification) and supporting literature (first author, patients' population, year, and type of publication) were compared between CPGs. Results Nine CPGs including recommendations on neuropathic pain could be selected and were assessed. In total, they used 149 references of which 72 (48%) were about cancer conditions, 39 (26%) about neuropathic pain, and only 3 about neuropathic pain in patients with cancer (2%). Only 28 (19%) references were shared between 2 or more guidelines. There was only one shared reference specifically related to cancer neuropathic pain. Recommendations and their evidence grading strongly differ between CPGs. Conclusion This work demonstrates an important heterogeneity between European recommendations on diagnosis and assessment of neuropathic pain in patients with cancer. The main weaknesses are the low level of evidence and the absence of specific data focusing on neuropathic pain in patients with cancer. We recommend that physicians dealing with neuropathic pain in patients with cancer should be specially trained, that a specific methodology to develop CPGs should followed, and that specific research should be developed on the diagnosis of neuropathic pain in patients with cancer.

Between 19% and 39% of patients with cancer pain suffer from neuropathic pain. Its diagnosis and treatment is still challenging. Yet, national clinical practice guidelines ( CPGs) have been developed in several European countries to assist practitioners in managing these patients safely and legally. The aim of this study was to assess the quality of the development and reporting of these CPGs. Methods In collaboration with the European Federation of IASP Chapters, a European inventory of CPGs was conducted. Inclusion criteria were at least one paragraph dedicated to the treatment of neuropathic pain in cancer. Using the Appraisal of Guidelines, Research and Evaluation II instrument, 2 appraisers independently assessed the quality of the development process of the included CPGs in 6 quality domains. Besides, CPGs developed by governmental organization were compared with those developed by professional societies using t-tests. Results Mean scores of the domains 'scope and purpose' (80%) and 'clarity of presentation' (61%) were satisfactory, 'stakeholder involvement' (58%), 'rigor of development' (57%), and 'editorial independence' (53%) were acceptable, and 'applicability' was insufficient (39%). Governmental guidelines had higher quality scores than professional society guidelines for domain 'stakeholder involvement' and 'editorial independence' ( P < 0.01). Conclusions The quality of the development process of the 9 included CPGs varied widely. CPGs should be developed within a structured guideline program, including methodological support. As developing a CPG is expensive and time-consuming, we recommend more international cooperation to increase quality and lower the development costs. [ABSTRACT FROM AUTHOR]

Introduction: Neuropathic pain is a common symptom, present in 39% of the patients with cancer pain. Treating this type of pain is challenging, as this patient group is often frail and has comorbidities which increase the risk of side events and hence influences their quality of life. Clinical practice guidelines (CPGs) can be helpful for clinicians, especially when scientific evidence is uncertain or weak. In this study, we focused on the quality of the review of the literature used in treatment recommendations in the selected European CPGs., Methods: In a previous study, 9 CPGs from European countries that contained at least one paragraph on treatment for neuropathic pain in cancer were included. Recommendations with their grade (according SIGN 55 classification) and supporting literature (first author, patients' population, year and type of publication) were compared between CPGs., Results: In all CPGs, amitriptylin was mentioned as the drug of first choice. Six guidelines proposed also gabapentinoids. Only 30 of the 163 citations (18%) were based on studies in patients with cancer. Seven CPGs did not argue the indirect evidence due to extrapolation of study results from non-cancer to patients with cancer., Conclusion: The majority of guideline development groups extrapolated their results from non-cancer publications to formulate recommendations. Consequently, these guidelines fail to address important issues such as altered kinetics and side effect profiles in these patients. We recommend creating specific recommendations by an international expert group for the treatment for neuropathic pain in patients with cancer supported by targeted research in patients with cancer., (© 2013 The Authors Pain Practice © 2013 World Institute of Pain.)
