Brief Summary

      Sezary syndrome (SS) is a rare, aggressive and advanced form of cutaneous T lymphoma with a
      poor prognosis (5-year survival rate varying between 24% and 52%). The treatments are only
      suspensive with short-term remissions. For the past fifteen years, therapeutic approaches
      have been based on depleting monoclonal antibodies (anti-CD52, anti-CCR4, anti-KIR3DL2,
      anti-CD70), or antibody-drug conjugates (anti-CD30). But while the efficacy of mogamulizumab
      on progression-free survival was reported in the phase III study, no study on a large cohort
      has compared the current overall survival of patients with Sezary syndrome to that before the
      era of monoclonal antibodies. In this context, we propose to report a large series of
      patients with Sézary syndrome in order to compare the current survival of patients with that
      of the pre-monoclonal antibodies era (1998-2003).

      The objective of this study is to assess the evolution of the overall survival of patients
      with Sezary syndrome since the early use of therapeutic monoclonal antibodies. The underlying
      hypothesis of this study is that the use of therapeutic monoclonal antibodies has improved
      the prognosis of these patients. Patients included in this retrospective study are patients
      with a Sezary syndrome diagnosed between 1998 and 2020.
