A Retrospective Study of Clinical, Phenotypic and Genetic Factors of Peripheral T-Cell Lymphomas

March 17, 2017 updated by: Takeda

A Retrospective Study of Clinical, Phenotypic and Genetic Factors of Peripheral T-Cell Lymphomas in the Spanish Population

The purpose of this study is to establish the distribution of peripheral T-cell lymphocyte (PTCL) subtypes by re-analysis and re-classification of samples according to the 2008 World Health Organization (WHO) classification of lymphoid neoplasms.

Detailed Description

This study is a retrospective, non-interventional and, post-authorization observational study of other designs (PAS-OD).

This multicenter trial will be conducted in Spain. Retrospective review of medical records and initial tumor biopsies of participants diagnosed with PTCL in the period of 6 years between 01/01/2008 and 31/12/2013 will be performed. Initial tumor biopsies and histological preparations, filed and previously anonymized, will be sent to the central laboratory for assessment.

Assessment of tumor biopsies and histological preparations of participants diagnosed with peripheral T-cell lymphoma (PTCL) in the six years between 01 January 2008 and 31 December 2013 will be performed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Distribution of Peripheral T-cell Lymphoma (PTCL) Subtypes
Time Frame: Up to 6 months
Distribution of PTCL subtypes by re-analysis and re-classification of samples according to the 2008 WHO classification of lymphoid neoplasms will be estimated.
Up to 6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants with Each Subtypes of PTCL
Time Frame: Up to 6 months
Percentage of participants with each subtypes of PTCL according to the WHO 2008 classification of lymphoid neoplasms will be reported.
Up to 6 months
Rate of Discrepancy Between the Initial Diagnosis and Re-analysis and Re-classification
Time Frame: Up to 6 months
Rate of discrepancy between the initial diagnosis of PTCL in participants and diagnosis by re-analysis and re-classification according to the WHO 2008 classification will be determined.
Up to 6 months
Expression of Cluster of Differentiation 30 (CD30) by Immunohistochemistry and Quantitative Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) in Different Subtypes of PTCL
Time Frame: Up to 6 months
Expression of CD30 by immunohistochemistry and quantitative RT-PCR in different subtypes of PTCL will be determined.
Up to 6 months
Correlation Between the Expression of CD30 and Lymphoid Lineage
Time Frame: Up to 6 months
Markers of T and B cells will be used in order to determine if CD30 expression occurs in tumor cells or other B-lineage.
Up to 6 months
Correlation Between the Expression of CD30, Prognostic Indices Used In PTCL and Survival
Time Frame: Up to 6 months
Survival includes progression free survival: period from date of start of treatment until tumor progression or death, whichever occurs first. Overall survival: period from date of diagnosis to the date of death.
Up to 6 months
Classification of Peripheral T-cell Lymphoma
Time Frame: Up to 6 months
The PTCL is classified according to the expression of CD30 and T-Cell Receptor ß (TCRß) and T-Cell Receptor γ (TCRγ) by immunohistochemistry (IHC).
Up to 6 months
T-cell Clonality in PTCL
Time Frame: Up to 6 months
Analysis of T-cell clonality in PTCL will be performed. Clonality defines the profile of gene rearrangement of T cell receptor and allow establishing whether proliferation is monoclonal.
Up to 6 months
Correlation Between Most frequent Mutations and Clinical, Phenotypic Factors
Time Frame: Up to 6 months
Distribution of the most frequent mutations in tumors and its correlation with clinical and phenotypic factors will be determined.
Up to 6 months
