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).

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.

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.

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

There is no cure for CTCL, but there are a variety of treatment options available and some CTCL patients are able to live normal lives with this cancer, although symptoms can be debilitating and painful, even in earlier stages. FDA approved treatments include the following:

- (1999) Denileukin diftitox (Ontak)

- (2000) Bexarotene (Targretin) a retinoid

- (2006) Vorinostat (Zolinza) a hydroxymate histone deacetylase (HDAC) inhibitor

- (2009) Romidepsin (Istodax) a cyclic peptide histone deacetylase (HDAC) inhibitor

Histone deacetylase (HDAC) inhibitors are shown to have antiproliferative and cytotoxic properties against CTCL.Other (off label) treatments include:

In 2010, the U.S. Food and Drug Administration granted orphan drug designation for a topical treatment for pruritus in cutaneous T-cell lymphoma to a pharmaceutical company called Elorac.

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

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

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.

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.

Treatment of some other, more aggressive, forms of lymphoma can result in a cure in the majority of cases, but the prognosis for patients with a poor response to therapy is worse. Treatment for these types of lymphoma typically consists of aggressive chemotherapy, including the CHOP or R-CHOP regimen. A number of people are cured with first-line chemotherapy. Most relapses occur within the first two years, and the relapse risk drops significantly thereafter. For people who relapse, high-dose chemotherapy followed by autologous stem cell transplantation is a proven approach.

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

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.

"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.

Of all cancers involving the same class of blood cell, 2% of cases are cutaneous T cell lymphomas. CTCL is more common in men and in African-American people. The incidence of CTCL in men is 1.6 times higher than in women.

There is some evidence of a relationship with human T-lymphotropic virus (HTLV) with the adult T-cell leukemia/lymphoma subtype. No definitive link between any viral infection or environmental factor has been definitely shown with other CTCL subtypes.

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

Nevertheless, the Working Formulation and the NHL category continue to be used by many. To this day, lymphoma statistics are compiled as Hodgkin's versus non-Hodgkin lymphomas by major cancer agencies, including the US National Cancer Institute in its SEER program, the Canadian Cancer Society and the IARC.

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.

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

The factors of poor prognosis for patients with thyroid lymphoma are advanced stage of the tumor, large size (>10 cm) as well as spreading to mediastinum. The overall survival for primary thyroid lymphoma is 50% to 70%, ranging from 80% in stage IE to less than 36% in stage IIE and IVE in 5 years.

Breast implant-associated ALCL is a recently recognized lymphoma and definitive management and therapy is under evaluation. However, it appears that removal of the implant, and resection of the capsule around the implant as well as evaluation by medical and surgical oncologists are cornerstones. Still under evaluation is the extent of capsulectomy: partial versus complete capsulectomy; similarly it is not defined the significance of replacement of the implant in the affected breast, or the removal of contralateral implant. Similarly, the value of radiation therapy and chemotherapy are under evaluation.

Currently, there is a drug, LDK378, undergoing Phase III clinical trials at Vanderbilt University that targets ALK positive small cell lung cancer, and has showed clinical promise in its previous clinical trials. Because approximately 70% of ALCL neoplasms are also ALK positive, there is hope that similar highly selective and potent ALK inhibitors may be used in the future to treat ALK positive cases of ALCL.

Radiotherapy is the most effective treatment for local disease either as the sole treatment for low-grade lymphoma or in combination with chemotherapy for intermediate- and high-grade lymphoma. Radiotherapy dose in range of 30-45 Gy administered in fractions are advised in treating the local orbital lymphomas.

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.

In certain eligible patients, a conditioning regimen of high-dose chemotherapy followed by an autologous stem cell transplant may be used to extend a period of first complete remission. Likewise, a recent study suggests that high dose therapy and autologous stem cell transplantation results in favorable outcomes for elderly patients with Non-Hodgkin's Lymphoma.

According to the Peripheral T-Cell Lymphoma Project, median overall survival is ten months, while median failure-free survival is only six months . The peripheral index for T-cell lymphoma is useful in defining prognosis for enteropathy-associated T-cell lymphoma. Among the most influential prognostic factors is bulky disease, defined by a tumor mass greater than 5 cm.

Autologous stem cell transplantation is feasible for selected patients with enteropathy-associated T-cell lymphoma and can yield durable disease control in a significant proportion of these patients. One study found a trend for better survival in patients transplanted in first complete or partial remission at four years (66% vs. 36%; P = .062).
