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).

Leukemia is rarely associated with pregnancy, affecting only about one in 10,000 pregnant women. Treatment for chronic lymphocytic leukemias can often be postponed until after the end of the pregnancy. If treatment is necessary, then giving chemotherapy during the second or third trimesters is less likely to result in pregnancy loss or birth defects than treatment during the first trimester.

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.

Leukemia is rarely associated with pregnancy, affecting only about 1 in 10,000 pregnant women. How it is handled depends primarily on the type of leukemia. Nearly all leukemias appearing in pregnant women are acute leukemias. Acute leukemias normally require prompt, aggressive treatment, despite significant risks of pregnancy loss and birth defects, especially if chemotherapy is given during the developmentally sensitive first trimester. Chronic myelogenous leukemia can be treated with relative safety at any time during pregnancy with Interferon-alpha hormones. Treatment for chronic lymphocytic leukemias, which are rare in pregnant women, can often be postponed until after the end of the pregnancy.

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

For most people with CLL, it is incurable by present treatments, so treatment is directed towards suppressing the disease for many years, rather than totally and permanently eliminating it. The primary chemotherapeutic plan is combination chemotherapy with chlorambucil or cyclophosphamide, plus a corticosteroid such as prednisone or prednisolone. The use of a corticosteroid has the additional benefit of suppressing some related autoimmune diseases, such as immunohemolytic anemia or immune-mediated thrombocytopenia. In resistant cases, single-agent treatments with nucleoside drugs such as fludarabine, pentostatin, or cladribine may be successful. Younger and healthier patients may choose allogeneic or autologous bone marrow transplantation in the hope of a permanent cure.

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

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.

CLL treatment focuses on controlling the disease and its symptoms rather than on an outright cure. CLL is treated by chemotherapy, radiation therapy, biological therapy, or bone marrow transplantation. Symptoms are sometimes treated surgically (splenectomy – removal of enlarged spleen) or by radiation therapy ("de-bulking" swollen lymph nodes).

Initial CLL treatments vary depending on the exact diagnosis and the progression of the disease, and even with the preference and experience of the health care practitioner. Any of dozens of agents may be used for CLL therapy. An initial treatment regimen that contains fludarabine, cyclophosphamide, and rituximab (known as FCR) has demonstrated higher overall response rates and complete response rates.

Chemotherapy is the initial treatment of choice, and most ALL patients receive a combination of medications. There are no surgical options because of the body-wide distribution of the malignant cells. In general, cytotoxic chemotherapy for ALL combines multiple antileukemic drugs tailored to each patient. Chemotherapy for ALL consists of three phases: remission induction, intensification, and maintenance therapy.

Due to presence of CNS involvement in 10–40% of adult patients at diagnosis, most providers start Central nervous system (CNS) prophylaxis and treatment during the induction phase, and continue it during the consolidation/intensification period.

Adult chemotherapy regimens mimic those of childhood ALL; however, are linked with a higher risk of disease relapse with chemotherapy alone. It should be known that 2 subtypes of ALL (B-cell ALL and T-cell ALL) require special considerations when it comes to selecting an appropriate treatment regimen in adult patients. B-cell ALL is often associated with cytogenetic abnormalities (specifically, t(8;14), t (2;8) and t(8;22)), which require aggressive therapy consisting of brief, high-intensity regimens. T-cell ALL responds to cyclophosphamide-containing agents the most.

As the chemotherapy regimens can be intensive and protracted, many patients have an intravenous catheter inserted into a large vein (termed a central venous catheter or a Hickman line), or a Portacath, usually placed near the collar bone, for lower infection risks and the long-term viability of the device.

Males usually endure a longer course of treatment than females as the testicles can act as a reservoir for the cancer.

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.

Natural killer (NK) cell therapy is used in pediatrics for children with relapsed lymphoid leukemia. These patients normally have a resistance to chemotherapy, therefore, in order to continue on, must receive some kind of therapy. In some cases, NK cell therapy is a choice.

NK cells are known for their ability to eradicate tumor cells without any prior sensitization to them. One problem when using NK cells in order to fight off lymphoid leukemia is the fact that it is hard to amount enough of them to be effective. One can receive donations of NK cells from parents or relatives through bone marrow transplants. There are also the issues of cost, purity and safety. Unfortunately, there is always the possibility of Graft vs host disease while transplanting bone marrow.

NK cell therapy is a possible treatment for many different cancers such as Malignant glioma.

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.

Typically, people who experience a relapse in their ALL after initial treatment have a poorer prognosis than those who remain in complete remission after induction therapy. It is unlikely that the recurrent leukemia will respond favorably to the standard chemotherapy regimen that was initially implemented, and instead these patients should be trialed on reinduction chemotherapy followed by allogeniec bone marrow transplantation. These patients in relapse may also receive blinatumomab, as it has shown to increase remission rates and overall survival rates, without increased toxic effects.

Low dose palliative radiation may also help reduce the burden of tumor inside or outside the central nervous system and alleviate some symptoms.

Recently, there has also been evidence and approval of use for dasatinib, a tyrosine kinase inhibitor. It has shown efficacy in cases of patients with Ph1-positive and imatinib-resistant ALL, but more research needs to be done on long term survival and time to relapse.

ANKL is treated similarly to most B-cell lymphomas. Anthracycline-containing chemotherapy regimens are commonly offered as the initial therapy. Some patients may receive a stem cell transplant.

Most patients will die 2 years after diagnosis.

In the United States, about 500 patients are diagnosed with Richter's transformation each year.

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

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

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.

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

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.

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.

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