Primary cutaneous lymphomas: exploration of 10-year data from supraregional mutlidisciplinary team meetings in Glasgow, UK

Primary cutaneous lymphomas (PCLs) are non- Hodgkin lymphomas, presenting in the skin. They are classified into cutaneous B-cell lymphomas (CBCLs) or cutaneous T-cell lymphomas (CTCLs). The most common CTCL subtypes are mycosis fungoides (MF) and Sezary syndrome (SS). All patient's cases should be discussed at a specialist multidisciplinary team (MDT) meeting. This is the first published review, to our knowledge, of PCL MDT case discussion in the UK. Patient cases between 2008 and 2019 were reviewed to assess: frequency of PCL subtype, documentation of CTCL staging and management of MF/ SS. Of 356, 103 (29%) were CBCLs and the majority (n = 200, 56%) were CTCLs. MF/SS was the diagnosis in 120 (34%). Staging was documented in 44% (n = 53) of patients with MF/SS. Management largely followed guidelines for MF/SS, topical corticosteroids were the most common treatment (n = 93, 78%). Frequency of PCL subtype is largely comparable with previously published data. Documentation of CTCL staging is low, but higher than other reports. Our work begins to address the gap in real-world data on CTCLs. A standardized approach to data collection would inform clinical practice.
