Assembling a consensus on actinic cheilitis: A Delphi study Seoane, Juan González Moles, Miguel Ángel Actinic cheilitis Consensus Delphi study Potentially malignant oral disorder Aims To discuss the terminology to define and classify actinic cheilitis (AC) and to build a consensus on the diagnostic and therapeutic approaches to AC. Methods Two-round Delphi study using a questionnaire including 34 closed sentences (9 on terminology and taxonomy, 5 on potential for malignant transformation, 12 on diagnostic aspects, 8 on treatment) and 8 open questions. Experts' agreement was rated using a Likert scale (1-7). Results A consensus was reached on 24 out 34 statements (73.5%) and on 5 out of 8 (62.5%) close-ended questions. The response rate was identical in both rounds (attrition of 0%). AC is the term with the highest agreement (median of 7 (strongly agree; IQR: 6-7)) and the lowest dispersion (VC = 21.33). 'Potentially malignant disorder' was the preferred classification group for AC (median of 7) and 85.6% of participants showing some level of agreement (CV < 50). Experts (66.75%) consider AC a clinical term (median: 7; IQR: 4-7) and believe definitive diagnosis can be made clinically (median: 6; IQR: 5-7), particularly by inspection and palpation (median: 5; IQR: 4-6). Histopathological confirmation is mandatory for the management of AC (median: 5; IQR: 2.5-7), even for homogeneous lesions (median: 5; IQR: 3.5-6). Consensus was reached on all treatment statements (VC < 50). Conclusions AC is a potentially malignant disorder with a significant lack of agreement on diagnostic criteria, procedures, biopsy indications and the importance of techniques to assist in biopsy. A consensus was reached on nomenclature and management of this disorder. 2021-06-22T11:35:53Z 2021-06-22T11:35:53Z 2021-05-16 info:eu-repo/semantics/article Seoane J... [et al.].
