Unlike many skin diseases, CTCL can lead to disabling symptoms, and advanced CTCL can even be fatal. Early studies investigating health-related quality of life (HRQOL) in patients with mycosis fungoides (MF) and S\u00e9zary syndrome (SS), common subtypes of CTCL, demonstrated significant impairment across numerous domains. The aim of this current study is to develop a core domain set (CDS) to identify the essential aspects of MF\/SS that influence HRQOL that should be measured in therapeutic clinical trials. In the future, this set of core concepts will be used to identify the best patient- reported outcome measure(s) (PROM) for HRQOL for MF\/SS clinical research.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>Multiple strategies will be used to generate candidate concepts: systematic review of the literature, qualitative study and a survey study of healthcare providers. A Delphi consensus process including a comprehensive group of stakeholders (patients, caregivers\/care partners, a multidisciplinary group of healthcare professionals, patient advocacy groups, pharmaceutical industry representatives, methodologists and government agencies) will be used to achieve consensus. Statistical corrections for multiple significance testing and false positive findings will be undertaken.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The study was submitted for and received institutional review board approval at the University of Washington (IRB# STUDY00018890 and STUDY00019407).
