A Retrospective Study of Clinical, Phenotypic and Genetic Factors of Peripheral T-Cell Lymphomas in the Spanish Population
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.
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.
Inclusion Criteria:
Participants diagnosed with PTCL in the six years between 01/01/2008 and 31/12/2013.
Availability of initial tumor biopsy diagnosis in paraffin block (node or core biopsy of 16-18mm).
PTCL subtypes permitted by WHO 2008 classification of lymphoid neoplasms:
Exclusion Criteria:
• Participants with an unavailable history (lost, empty or not recoverable).
