Childhood Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Chronic Myeloproliferative Neoplasms
Myeloproliferative neoplasms are a group of diseases in which the bone marrow makes too many red blood cells, white blood cells, or platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells:Red blood cells that carry oxygen and other substances to all tissues of
Childhood Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - High-Stage Childhood Anaplastic Large Cell Lymphoma Treatment
Children and adolescents with high-stage (stage III or IV) anaplastic large cell lymphoma have a disease-free survival of approximately 60% to 75%.[1,2,3,4,5,6] It is unclear which strategy is best for the treatment of high-stage anaplastic large cell lymphoma. The German Berlin-Frankfurt-Munster (BFM) group used six cycles of intensive pulsed therapy, similar to their B-cell non-Hodgkin lymphoma (NHL) therapy (GER-GPOH-NHL-BFM-90 [NHL-BFM-90]).; [Level of evidence: 1iiA] Building on these results, the European Intergroup for Childhood NHL (EICNHL) group conducted the FRE-IGR-ALCL99 study (based on the GER-GPOH-NHL-BFM-90 regimen). First, this randomized study demonstrated that methotrexate 1 g/m2 infused over 24 hours plus intrathecal methotrexate and methotrexate 3 g/m2 infused over 3 hours without intrathecal methotrexate yielded similar outcomes.[Level of evidence: 1iiC] However, methotrexate 3 g/m2 over 3 hours had less toxicity than methotrexate 1 g/m2 over 24
Chronic Lymphocytic Leukemia
Chronic Lymphocytic Leukemia is a malignant blood disorder in which there is an increased number of white blood cells formed in the lymphoid tissue. This uncontrolled buildup and enlargement of lymphoid tissue can occur in various sites of the body such as the lymph nodes,spleen,bone marrow,and lungs. There are many different forms of Leukemia which are all characterized by an overabundance ...
Childhood Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Low-Stage Childhood NHL Treatment
Patients with stage I and II disease have an excellent prognosis, regardless of histology. A Children's Cancer Group study demonstrated that pulsed chemotherapy with cyclophosphamide, vincristine, methotrexate, and prednisone (COMP) administered for 6 months for low-stage (stage I or II) nonlymphoblastic non-Hodgkin lymphoma (NHL) was equivalent to 18 months of therapy with radiation to sites of disease, resulting in more than 85% disease-free survival (DFS) and more than 90% overall survival (OS). However, patients with lymphoblastic lymphoma had a much inferior outcome.[1,2] A Pediatric Oncology Group (POG) study tested 9 weeks of short, pulsed chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), with or without radiation to involved sites and with or without 24 weeks of maintenance chemotherapy. The results showed no benefit of radiation or maintenance chemotherapy, but the DFS for nonlymphoblastic lymphoma was superior to that of

Childhood Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Lymphoproliferative Disease Associated With Immunodeficiency in Children
Regardless of the etiology of the immune defect, immunodeficient children with lymphoma have a worse prognosis than does the general population with non-Hodgkin lymphoma (NHL).[1,2,3,4] One potential exception is the more indolent low-grade lymphomas (e.g., mucosa-associated lymphoid tissue [MALT] lymphomas), which have developed in patients with common variable immunodeficiency or other immunodeficient states.[5,6] If the disease is localized and amenable to complete surgical resection and/or radiation therapy, the outcome is quite favorable; however, most NHL in this population is high-stage (stage III or IV) and requires systemic cytotoxic therapy. These patients usually tolerate cytotoxic therapy poorly, with increased morbidity and mortality due to increased infectious complications and often increased end-organ toxicities. (Refer to the PDQ summary on Adult Non-Hodgkin Lymphoma Treatment for more information about MALT lymphomas.)In the era of highly active antiretroviral

Adult Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Indolent NHL
Indolent non-Hodgkin lymphoma (NHL) includes the following subtypes:Follicular lymphoma.Lymphoplasmacytic lymphoma (Waldenström macroglobulinemia).Marginal zone lymphoma.Splenic marginal zone lymphoma.Primary cutaneous anaplastic large cell lymphoma.Follicular LymphomaFollicular lymphoma comprises 20% of all NHLs and as many as 70% of the indolent lymphomas reported in American and European clinical trials.[1,2,3] Most patients with follicular lymphoma are age 50 years and older and present with widespread disease at diagnosis. Nodal involvement is most common and is often accompanied by splenic and bone marrow disease. Rearrangement of the bcl-2 gene is present in more than 90% of patients with follicular lymphoma; overexpression of the bcl-2 protein is associated with the inability to eradicate the lymphoma by inhibiting apoptosis.PrognosisDespite the advanced stage, the median survival ranges from 8 to 15 years, leading to the
Adult Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview
Many of the improvements in childhood cancer survival have been made using combinations of known and/or new agents that have attempted to improve the best available, accepted therapy. Clinical trials in pediatrics are designed to compare potentially better therapy with therapy that is currently accepted as standard. This comparison may be done in a randomized study of two treatment arms or by evaluating a single new treatment and comparing the results with those previously obtained with standard therapy. All children with non-Hodgkin lymphoma (NHL) should be considered for entry into a clinical trial. Treatment planning by a multidisciplinary team of cancer specialists with experience treating tumors of childhood is strongly recommended to determine, coordinate, and implement treatment to achieve optimal survival. Children with NHL should be referred for treatment by a multidisciplinary team of pediatric oncologists at an institution with experience in treating pediatric cancers.
Childhood Non-Hodgkin Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment for Indolent, Recurrent Adult NHL
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
