A Tissue Repository for the Collection of Samples From Patients With Cutaneous T Cell Lymphoma and Healthy Volunteers
This document is a protocol for a non-interventional human research study in which the investigator hopes to better understand the changes that take place in T cells in Cutaneous T-cell lymphoma (CTCL). The purpose of this study is to establish a protocol for the collection and storage of tissue samples from patients with CTCL for future research studies. Collection and storage of tissue samples from control patients will also be carried out.
• Patients with CTCL or Lymphomatoid Papulosis (LYP): a clinical or histologic diagnosis of a) newly diagnosed, b) progressive, or c) relapsed CTCL or LYP who are initiating or changing therapy.
• Patients with Sézary Syndrome (SS) or stage IV B CTCL as defined by blood involvement on flow cytometry or morphology: (1) ≥1000/μL Sézary cells by morphology; (2) Cluster of differentiation 4 (CD4)/cluster of differentiation 8 (CD8) ratio ≥10; (3) CD4+cluster of differentiation 7 (CD7)- cells ≥40 percent; (4) or CD4+cluster of differentiation 26 (CD26)- cells ≥30 percent.
