In general, treatment with standard agents rarely produces a cure in patients whose disease has relapsed. Sustained remissions after relapse can often be obtained in patients with indolent lymphomas, but relapse will usually ensue. Favorable survival after relapse has been associated with an age younger than 60 years, complete remission rather than partial remission, and duration of response longer than 1 year. Even the most favorable subset, however, has a tenfold greater mortality compared with age-adjusted U.S. population rates. Patients who experience a relapse with indolent lymphoma can often have their disease controlled with single agent or combination chemotherapy, rituximab (an anti-CD20 monoclonal antibody), lenalidomide, radiolabeled anti-CD20 monoclonal antibodies, or palliative radiation therapy.[2,3] Long-term freedom from second relapse, however, is uncommon and multiple relapses will usually occur. Patients with indolent lymphoma may experience a relapse with a more aggressive histology. If the clinical pattern of relapse suggests that the disease is behaving in a more aggressive manner, a biopsy should be performed. Documentation of conversion to a more aggressive histology requires an appropriate change to therapy applicable to that histologic type. Rapid growth or discordant growth between various disease sites may indicate a histologic conversion.
In a retrospective review of 325 patients between 1972 and 1999, the risk of histologic transformation was 30% by 10 years from diagnosis. In this series, high risk factors for subsequent histologic transformation were advanced stage, high-risk Follicular Lymphoma International Prognostic Index, and expectant management. The median survival after transformation was 1 to 2 years, with 25% of patients alive at 5 years and with approximately 10% to 20% of patients alive 10 years after re-treatment.
Non-Hodgkin lymphoma is diagnosed by a tissue biopsy. If there is an enlarged, painless lymph node, without of an infection, a biopsy will be needed.
To perform a lymph node biopsy a doctor will cut into the lymph node to remove a sample of tissue or remove the entire lymph node. If the biopsy shows non-Hodgkin lymphoma, further testing will be needed to determine the specific type as well as to determine the stage of disease. Depending on your specific symptoms, the type of the lymphoma, its...
(Refer to the Treatment for Aggressive, Recurrent Adult NHL section of this summary for descriptions of the regimens used to treat histologic conversions.) The durability of the second remission may be short, and clinical trials should be considered.
