T-Cell Lymphoma Gets Its Own NCCN Treatment Guideline

HOLLYWOOD, Florida—The management of peripheral T-cell lymphoma may become more uniform with the release of the first set of clinical practice guidelines for the disease from the National Comprehensive Cancer Network (NCCN). "This is not a common disease, but it exists. There was a sense that clinicians were not treating patients with any kind of a uniform approach, so this is the beginning of such an approach," Leo I. Gordon, MD, Abby & John Friend Professor of Cancer Research, Northwestern University Feinberg School of Medicine, told ONI.

Peripheral T-cell lymphoma (unspecified) makes up approximately 5% to 7% of all non-Hodgkin's lymphoma cases and between 60% and 70% of T-cell lymphomas. A fine-needle aspiration biopsy alone is not sufficient for the initial diagnosis of peripheral T-cell lymphoma. Essential work-up involves adequate immunophenotyping, including a full paraffin panel; cell surface marker analysis by flow cytometry; and additional immunohistochemical studies if needed to establish lymphoma subtype. Molecular genetic analysis is also required to detect antigen receptor gene rearrangements and variants, Dr. Gordon said.

The guidelines detail all steps to follow during the work-up of a patient with suspected peripheral T-cell lymphoma and recommend that prophylaxis for tumor lysis syndrome be considered during induction therapy for stage I and II disease. Follow-up therapy for complete response, partial response, and no response or progressive disease, as well as end of treatment restaging for these categories, is described.

The NCCN T-cell lymphoma panel recommended that patients be enrolled in a clinical trial whenever possible for optimal management.

First-line therapy should encompass aggressive regimens (see Table). The panel also noted that intermediate- and high-risk patients be consolidated with high-dose therapy and autologous or allogeneic stem cell support.

Recommended second-line therapy includes regimens with intent for stem cell rescue and therapy with palliative intent (see Table).
