General Information About Adult Non-Hodgkin Lymphoma (NHL)

The NHLs are a heterogeneous group of lymphoproliferative malignancies with differing patterns of behavior and responses to treatment.[1]

Like Hodgkin lymphoma, NHL usually originates in lymphoid tissues and can spread to other organs. NHL, however, is much less predictable than Hodgkin lymphoma and has a far greater predilection to disseminate to extranodal sites. The prognosis depends on the histologic type, stage, and treatment.

Anatomy of the lymph system.

The NHLs can be divided into two prognostic groups: the indolent lymphomas and the aggressive lymphomas.

Indolent NHL types have a relatively good prognosis with a median survival as long as 20 years, but they usually are not curable in advanced clinical stages.[3] Early-stage (stage I and stage II) indolent NHL can be effectively treated with radiation therapy alone. Most of the indolent types are nodular (or follicular) in morphology.

The aggressive type of NHL has a shorter natural history, but a significant number of these patients can be cured with intensive combination chemotherapy regimens.

In general, with modern treatment of patients with NHL, overall survival at 5 years is over 60%. Of patients with aggressive NHL, more than 50% can be cured. The vast majority of relapses occur in the first 2 years after therapy. The risk of late relapse is higher in patients who manifest both indolent and aggressive histologies.[4]
