T-Cell Lymphomas, Version 2.2022, NCCN Clinical Practice Guidelines in Oncology.

Area of Science:

• Hematology
• Oncology
• Lymphoma Research

Background:

• Peripheral T-cell lymphomas (PTCLs) represent approximately 10% of non-Hodgkin lymphomas.
• PTCLs are a heterogeneous group of lymphoproliferative disorders originating from mature T cells.
• Key subtypes include PTCL-not otherwise specified, angioimmunoblastic T-cell lymphoma, and anaplastic large cell lymphoma (ALK-positive and ALK-negative).

Purpose of the Study:

• To provide an overview of the diagnosis and treatment of PTCLs.
• To summarize current recommendations for T-cell lymphomas based on NCCN Guidelines.
• To highlight the heterogeneity and common subtypes within PTCLs.

Main Methods:

• Review of the NCCN Guidelines for T-Cell Lymphomas.
• Discussion of diagnostic criteria and treatment modalities for PTCL subtypes.
• Synthesis of information on the most prevalent PTCL classifications.

Main Results:

• PTCL-not otherwise specified is the most frequent subtype.
• Angioimmunoblastic T-cell lymphoma and anaplastic large cell lymphomas are significant subtypes.
• The NCCN Guidelines offer a framework for managing these complex lymphomas.

Conclusions:

• Accurate diagnosis and subtype classification are crucial for effective PTCL management.
• Treatment strategies for PTCLs are guided by established clinical guidelines.
• Ongoing research and adherence to guidelines are essential for improving patient outcomes in PTCL.
