Effect of Denileukin Diftitox on Immune System in CTCL Patients
Cutaneous T-cell LymphomaSezary Syndrome1 moreThis is a blood and tissue study to determine the effect of the drug called denileukin diftitox on the immune system cells that may be involved in patient response to their cutaneous t-cell lymphoma. Patients who are undergoing standard of care therapy with denileukin diftitox will be invited to participate. Blood and tissue samples will be obtained at baseline, day 5 and day 19 in up to the first 4 cycles of denileukin diftitox.
Analysis of Cutaneous and Hematologic Disorders by High-Throughput Nucleic Acid Sequencing
Cutaneous LymphomaOther Skin Disorders2 moreThe goal of this study is to identify genetic changes associated with the initiation, progression, and treatment response of response of cutaneous and hematologic disorders using recently developed high-throughput sequencing technologies. The improved understanding of the genetic changes associated with cutaneous and hematologic disorders may lead to improved diagnostic, prognostic and therapeutic options for these disorders.
In Vitro Evaluation of Immune Responses in Cutaneous T-Cell Lymphoma (CTCL)
Cutaneous T-cell LymphomaSezary Syndrome1 moreThis is an in vitro evaluation of cutaneous T-cell lymphoma using patients' blood and tissue to evaluate immune responses related to identified tumor populations and dendritic/CD 8 cells.
Cell-free Circulating DNA in Primary Cutaneous Lymphomas
Mycosis FungoidesLymphoma2 moreTo evaluate the possibility of detecting cell-free circulating tumoral DNA in potentially aggressive primary cutaneous lymphomas, the investigator opted to search a representative tumor sample mutation in the blood of these patients, by digital PCR. Patients with mycosis fungoides, primary cutaneous T-cell lymphoma helper follicular phenotype and primary cutaneous diffuse large B-cell lymphoma, leg-type will be included and 4 blood samples will be collected during 12 months.
Clinical Study Assessing Outcomes, Adverse Events, Treatment Patterns, and Quality of Life in Patients...
Mycosis FungoidesThe Valchlor PROVe study is a multi-center, prospective, observational, US-based drug study that longitudinally follows patients with Mycosis Fungoides Cutaneous T-cell Lymphoma (MF-CTCL) who are receiving therapy with Valchlor. Patients will be followed prospectively for a maximum of 2 years from the date of signed informed consent (enrollment) until end of study. Continuation in the study is not contingent on continuation of Valchlor.
T Cell Repertoire Analysis of Immune Mediated Skin Diseases
PsoriasisMycosis FungoidesThis study is designed to identify the cells of the immune system that cause skin disease such as psoriasis and mycosis fungoides. Blood samples from many patients will be compared in hopes of finding common cells and molecules responsible for skin diseases. Results of this study will increase our knowledge about immune mediated skin disease.
Early Diagnosis of Mycosis Fungoides
Cutaneous T Cell LymphomaMycosis fungoides (MF) is an epidermotropic cutaneous T cell lymphoma characterized by the accumulation of CD4+ T-lymphocytes in the skin. Early MF presents as erythematous patches and/or infiltrated plaques. The diagnosis of early MF is a major diagnostic challenge and the differential diagnosis with inflammatory dermatoses is often very difficult. The histopathological diagnosis is also difficult and delayed. Therefore, it is important to develop biomarkers and/or a combination of biomarkers in order to improve the early diagnostic of MF. In a previous trial, investigators included 490 patients in a study aiming at identifying skin biomarkers of early MF. Several activating and inhibiting KIRs were found to be interesting for the skin diagnostic of MF, mainly KIR2DL4 and KIR3DL2. Investigators later evaluated blood biomarkers in patients with erythrodermic MF and Sezary Syndrome (SS). This French institutional study demonstrated that the identification by PCR of a combination of 4 blood markers (CD158k/KIR3DL2, PLS3/T-Plastin, Twist and NKp46) allowed a reliable diagnosis of lymphoma in erythrodermic patients. This previously published study interestingly showed that 30% to 50% of patients with early MF expressed at least one of these biomarkers in the blood (unpublished data). Other groups also recently showed that TOX can be a diagnostic tool for MF. The aim of this study is to establishing an accurate blood diagnosis for early suspected MF by demonstrating that newly identified biomarkers or their combination [5 cutaneous KIR receptor markers (KIR2DS1, KIR2DS3, KIR3DL1, KIR2DL4, KIR3DL2) and 5 blood biomarkers (TOX, Twist-1, PLS3/T-plastin, KIR3DL2, NKp46)] are differentially expressed by patients with MF and patients with inflammatory dermatoses closely resembling MF lesions. Statistical analysis will establish the best combination of blood biomarkers allowing the differentiation between the two groups of patients, combination that could represent a suitable diagnostic tool for early MF.
