Aggressive NHL

    Aggressive non-Hodgkin lymphoma (NHL) includes the following subtypes:

    • Diffuse large B-cell lymphoma.
    • Mediastinal large B-cell lymphoma (primary mediastinal large B-cell lymphoma).
    • Follicular large cell lymphoma.
    • Anaplastic large cell lymphoma.
    • Extranodal NK-/T-cell lymphoma.
    • Lymphomatoid granulomatosis.
    • Angioimmunoblastic T-cell lymphoma.
    • Peripheral T-cell lymphoma.
    • Enteropathy-type intestinal T-cell lymphoma.
    • Intravascular large B-cell lymphoma (intravascular lymphomatosis).
    • Burkitt lymphoma/diffuse small noncleaved-cell lymphoma.
    • Lymphoblastic lymphoma.
    • Adult T-cell leukemia/lymphoma.
    • Mantle cell lymphoma.
    • Polymorphic posttransplantation lymphoproliferative disorder.
    • True histiocytic lymphoma.
    • Primary effusion lymphoma.

    Understanding Non-Hodgkin Lymphoma -- Diagnosis & 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...

    Diffuse large B-cell lymphoma (DLBCL) is the most common of the NHLs and comprises 30% of newly diagnosed cases.[1] Most patients present with rapidly enlarging masses, often with both local and systemic symptoms (designated B symptoms with fever, recurrent night sweats, or weight loss). (Refer to the PDQ summary on Fever, Sweats, and Hot Flashes and the PDQ summary on Nutrition in Cancer Care for more information on weight loss.)

    Some cases of large B-cell lymphoma have a prominent background of reactive T-cells and often of histiocytes, so-called T-cell/histiocyte-rich large B-cell lymphoma. This subtype of large cell lymphoma has frequent liver, spleen, and bone marrow involvement; however, the outcome is equivalent to that of similarly staged patients with diffuse large B-cell lymphoma.[2,3,4] Some patients with diffuse large B-cell lymphoma at diagnosis have a concomitant indolent small B-cell component; while overall survival (OS) appears similar after multidrug chemotherapy, there is a higher risk of indolent relapses.[5]

    Prognosis

    The vast majority of patients with localized disease are curable with combined–modality therapy or combination chemotherapy alone.[6] For patients with advanced-stage disease, 50% of presenting patients are cured with doxorubicin-based combination chemotherapy and rituximab.[7,8,9]

    An International Prognostic Index (IPI) for aggressive NHL (diffuse large cell lymphoma) identifies five significant risk factors prognostic of OS:[10]

    1. Age (≤60 years vs. >60 years).
    2. Serum lactate dehydrogenase (LDH) (normal vs. elevated).
    3. Performance status (0 or 1 vs. 2–4).
    4. Stage (stage I or stage II vs. stage III or stage IV).
    5. Extranodal site involvement (0 or 1 vs. 2–4).
