Currently PTCL is treated similarly to B-cell lymphomas. However, in recent years, scientists have developed techniques to better recognize the different types of lymphomas, such as PTCL. It is now understood that PTCL behaves differently from B-cell lymphomas and therapies are being developed that specifically target these types of lymphoma. Currently, however, there are no therapies approved by the US Food and Drug Administration (FDA) specifically for PTCL. Anthracycline-containing chemotherapy regimens are commonly offered as the initial therapy. Some patients may receive a stem cell transplant. Novel approaches to the treatment of PTCL in the relapsed or refractory setting are under investigation.

Pralatrexate is one compound currently under investigations for the treatment of PTCL. For information please consult the US clinical trials database (http://www.clinicaltrials.gov).

Of all cancers involving the same class of blood cell (lymphoproliferative disorders), 22% of cases are follicular lymphomas.

Pralatrexate is one compound currently under investigations for the treatment of PTCL.

Of all cancers involving the same class of blood cell, 2.3% of cases are Burkitt lymphoma. Epstein-Barr virus infection is strongly correlated with this cancer.

In general, the first line of treatment for Burkitt’s lymphoma is intensive chemotherapy. A few of these regimens are: the GMALL-B-ALL/NHL2002 protocol, the modified Magrath regimen (R-CODOX-M/IVAC). COPADM, hyper-CVAD, and the Cancer and Leukemia Group B (CALGB) 8811 regimen; these can be associated with rituximab. In older patients treatment may be dose-adjusted EPOCH with rituximab.

The effects of the chemotherapy, as with all cancers, depend on the time of diagnosis. With faster-growing cancers, such as Burkitt's, the cancer actually responds faster than with slower-growing cancers. This rapid response to chemotherapy can be hazardous to the patient, as a phenomenon called "tumor lysis syndrome" could occur. Close monitoring of the patient and adequate hydration is essential during the process. Since Burkitts lymphoma has high propensity to spread to the central nervous system (lymphomatous meningitis), intrathecal chemotherapy with methotrexate and/or ARA-C and/or prednisolone is given alongside with systemic chemotherapy.

Chemotherapy

- cyclophosphamide

- doxorubicin

- vincristine

- methotrexate

- cytarabine

- ifosfamide

- etoposide

- rituximab

Other treatments for Burkitt's lymphoma include immunotherapy, bone marrow transplants, stem cell transplant, surgery to remove the tumor, and radiotherapy.

There is no consensus regarding the best treatment protocol. Several considerations should be taken into account including age, stage, and prognostic scores (see International Prognostic Index). Patients with advanced disease who are asymptomatic might benefit from a watch and wait approach, as early treatment does not provide survival benefit. When patients are symptomatic, specific treatment is required, which might include various combinations of alkylators, nucleoside analogues, anthracycline-containing chemotherapy regimens (e.g., CHOP), monoclonal antibodies (e.g. rituximab),

radioimmunotherapy, autologous (self) and allogeneic (donor) hematopoietic stem cell transplantation. Follicular lymphoma is regarded as incurable, unless the disease is localized, in which case it can be cured by local irradiation. Although allogeneic stem cell transplantation may be curative, the mortality from the procedure is too high to be a first line option.

In 2010 rituximab was approved by the European Commission for first-line maintenance treatment of follicular lymphoma. Pre-clinical evidence suggests that rituximab could be also used in combination with integrin inhibitors to overcome the resistance to rituximab mediated by stromal cells . However, follicular lymphoma which is CD20 negative will not benefit from Rituximab, which targets CD20.

Trial results released in June 2012 show that bendamustine, a drug first developed in East Germany in the 1960s, more than doubled disease progression-free survival when given along with rituximab. This combination therapy also left patients with fewer side effects than the older treatment (a combination of five drugs—rituximab, cyclophosphamide (Cytoxan), doxorubicin (Adriamycin), vincristine and prednisone, collectively called R-CHOP).

There are many recent and current clinical trials for follicular lymphoma. For example, personalised idiotype vaccines have shown promise, particularly as upfront therapy, but have still to prove their efficacy in randomized clinical trials.

CHOP frequently induces remission initially, but most patients relapse and die within two years. Autologous bone marrow transplantation is currently being investigated in the treatment of hepatosplenic lymphoma. Allogeneic bone marrow transplant has been proven to attain remission for over five years and possibly cure hepatosplenic lymphoma.

Multiagent chemotherapy is recommended, but the preferred regimen is controversial, as is consolidative radiotherapy.

One study has suggested improved overall survival in response to chemotherapy for African Americans.

There are no proven standards of treatment for MCL, and there is no consensus among specialists on how to treat it optimally. Many regimens are available and often get good response rates, but patients almost always get disease progression after chemotherapy. Each relapse is typically more difficult to treat, and relapse is generally faster. Fortunately, regimens are available that will treat relapse, and new approaches are under test. Because of the aforementioned factors, many MCL patients enroll in clinical trials to get the latest treatments.

There are four classes of treatments currently in general use: chemotherapy, immune based therapy, radioimmunotherapy and new biologic agents. The phases of treatment are generally: frontline, following diagnosis, consolidation, after frontline response (to prolong remissions), and relapse. Relapse is usually experienced multiple times.

6% of non-Hodgkin lymphoma cases are mantle cell lymphoma. As of 2015, the ratio of males to females affected is about 4:1.

Of all cancers involving the same class of blood cell, 8% of cases are MALT lymphomas.

Chemotherapy with CHOP, infusional EPOCH, hyperCVAD, and CODOX-M/IVAC is often used. The prognosis is generally poor, for example 6 to 7 months and 14 months.

The type of treatment selected depends on stage of disease, the age of the patient, the patient's overall health, any signs or symptoms related to the lymphoma, and the location of the disease.

Treatment Options for Gastric MALT

For gastric MALT lymphoma, the initial treatment is antibiotic therapy to get rid of Helicobacter pylori, which is typically given for two weeks. Approximately 70 percent to 90 percent of patients respond to antibiotic therapy, and approximately half of the patients require no further treatment. If the lymphoma relapses after antibiotic therapy, there are many additional treatment options available, including (in alphabetical order):

- Bendamustine

- Bortezomib

- Fludarabine

- Radiation (low dose)

- Rituximab

- Surgical excision

Treatment Options for Non-gastric MALT

Non-gastric MALT can appear in a variety of areas throughout the body. Therefore, treatment is usually based on the exact location and extent of spread. Treatment typically includes surgery for certain sites (lung, breast) or radiation therapy with or without chemotherapy. More advanced disease usually includes immunoradiotherapy with chemotherapy. Among the common first-line treatments are bendamustine plus rituximab and R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). Recently, antibiotic therapy such as doxycycline has been shown to be effective in marginal zone lymphoma that affects the area around the eye ("ocular adnexal marginal zone lymphoma").

Treatment Options for Nodal Marginal Zone Lymphoma

Because nodal marginal zone lymphoma is most often a slow-growing disease, doctors may defer treatment until symptoms appear, an approach called "watch and wait" or "watchful waiting." When treatment is necessary, options include radiation therapy, chemotherapy, and other treatments commonly used in other types of slow-growing lymphomas, such as follicular lymphoma.

Treatment Options for Splenic Marginal Zone Lymphoma

Several treatment options exist for splenic marginal zone lymphoma. Some patients undergo surgical removal of the spleen (splenectomy) or, for those patients who are not surgical candidates, low-dose radiation of the spleen. Other patients may receive rituximab, a monoclonal antibody, with or without chemotherapy.

"MALT lymphoma" is exquisitely immunotherapy sensitive. Chemotherapy is reserved for those uncommon patients with disseminated disease at presentation or lack of response to local treatment. Rituximab, the anti-CD20 chimeric antibody, is a key component of therapy. Responses vary from 55% to 77% with monotherapy and 100% in combination with chemotherapy. Oral alkylating agents such as cyclophosphamide or chlorambucil have been administered for a median duration of 12 months with high rates of disease control (CR up to 75%) but appear not to be active in t(11;18) disease. The purine nucleoside analogs fludarabine and cladribine also demonstrate activity, the latter conferring a CR rate of 84% (100% in those with gastric primaries) in a small study. A pivotal study of rituximab plus chlorambucil compared with chlorambucil alone (IELSG-19 study, n = 227) demonstrated a significantly higher CR rate (78% vs. 65%; p = 0.017) and 5-year EFS (68% vs. 50%; p = 0.024) over chlorambucil alone. However, 5-year OS was not improved (88% in both arms). First-line treatment of choice is generally rituximab in combination with single alkylating agents or fludarabine, or a combination of all three drugs. The final results of this study, including the later addition of a rituximab-alone arm, are pending.

Two other genetic alterations are known:

- t(1;14)(p22;q32), which deregulates BCL10, at the locus 1p22.

- t(14;18)(q32;q21), which deregulates MALT1, at the locus 18q21.

These seem to turn on the same pathway as API2-MLT (i.e., that of NF-κB). They both act upon IGH, which is at the locus 14q32.

The two types of lymphoma research are clinical or translational research and basic research. Clinical/translational research focuses on studying the disease in a defined and generally immediately patient-applicable way, such as testing a new drug in patients. Studies may focus on effective means of treatment, better ways of treating the disease, improving the quality of life for patients, or appropriate care in remission or after cures. Hundreds of clinical trials are being planned or conducted at any given time.

Basic science research studies the disease process at a distance, such as seeing whether a suspected carcinogen can cause healthy cells to turn into lymphoma cells in the laboratory or how the DNA changes inside lymphoma cells as the disease progresses. The results from basic research studies are generally less immediately useful to patients with the disease, but can improve scientists' understanding of lymphoma and form the foundation for future, more effective treatments.

Currently Aggressive NK-cell leukemia, being a subtype of PTCL, is treated similarly to B-cell lymphomas. However, in recent years, scientists have developed techniques to better recognize the different types of lymphomas, such as PTCL. It is now understood that PTCL behaves differently from B-cell lymphomas and therapies are being developed that specifically target these types of lymphoma. Currently, however, there are no therapies approved by the U.S. Food and Drug Administration (FDA) specifically for PTCL. Anthracycline-containing chemotherapy regimens are commonly offered as the initial therapy. Some patients may receive a stem cell transplant. Novel approaches to the treatment of PTCL in the relapsed or refractory setting are under investigation.

There is no known cause for any type of Marginal Zone non-Hodgkins lymphoma, but it occurs when the body produces large amounts of abnormal lymphocytes.

Factors that may increase an individuals chance of developing nodal MZL are being over the age of 60 and having been infected with hepatitis C virus. Factors that may increase an individuals chance of developing MALT lymphoma include being over the age of 50, having an autoimmune condition (rheumatoid arthritis, Hashimoto's thyroiditis), and long lasting chronic inflammation due to infection (H.pylori, Sjogren syndrome, chlamidia infection, Borrelia infection, Campylobacter jejuni infection). Factors that increase an individuals risk of developing splenic MZL include the hepatitis C virus, Epstein-Barr virus, malaria, Sjogren syndrome, and lupus.

In order to reduce the chances of developing MZL, an individual can decrease their exposure to the possible risk factors.

A second regimen under evaluation is R-EPOCH (rituximab with etoposide-prednisone-vincristine-doxorubicin-cyclophosphamide), which demonstrated a 5-year progression-free survival (PFS) of 79% in a phase II trial. A phase III trial, CALGB 50303, is now comparing R-EPOCH with R-CHOP in patients with newly diagnosed DLBCL.

One area of active research is on separating patients into groups based on their prognosis and how likely they are to benefit from different drugs. Methods like gene expression profiling and next-generation sequencing may result in more effective and more personalized treatment.

The most common chemotherapy used for non-Hodgkin lymphoma is R-CHOP.

Hodgkin lymphoma typically is treated with radiotherapy alone, as long as it is localized.

Advanced Hodgkin disease requires systemic chemotherapy, sometimes combined with radiotherapy. Chemotherapy used includes the ABVD regimen, which is commonly used in the United States. Other regimens used in the management of Hodgkin lymphoma include BEACOPP and Stanford V. Considerable controversy exists regarding the use of ABVD or BEACOPP. Briefly, both regimens are effective, but BEACOPP is associated with more toxicity. Encouragingly, a significant number of people who relapse after ABVD can still be salvaged by stem cell transplant.

Treatment with conventional immunochemotherapy is usually indicated; in younger patients, allogeneic bone marrow transplantation may be curative.

The germinal center subtype has the best prognosis,with 66.6% of treated patients surviving more than five years. The IPI score is used in prognosis in clinical practice. Lenalidomide has been recently shown to improve outcomes in the non-germinal center subtype. Ratios of immune effectors such as CD4 and CD8 to immune checkpoints such as PD-L1 and M2 macrophages are independent of and additive to the cell of origin and IPI in DLBCL, and are applicable to paraffin-embedded biopsy specimens. These findings might have potential implications for selection of patients for checkpoint blockade and/or lenalidomide within clinical trials.

For children with diffuse large B-cell lymphomas, most studies have found 5-year survival rates ranging from about 70% to more than 90%.

The lymphoma is more common in the young and in males.

A 2008 study found an increased risk of ALCL of the breast in women with silicone breast implants (protheses), although the overall risk remained exceedingly low due to the rare occurrence of the tumor.
