Evaluation of relative TL in CTCL patients. (A) qPCR showed that TL was significantly shorter in SS and T-MF patient tumor cells than in healthy lymphocytes. C-ALCL patient tumor cells exhibited a TL similar to that in healthy lymphocytes. (B) IQFISH measurement confirmed that TL was shorter in SS blood samples than in healthy lymphocytes. (C) Graph shows that TL in SS blood samples was not influenced by older age in patients. TL was shorter in SS group than in age-matched controls. A.U, arbitrary units.
