Recent trials that have made use of new types of chemotherapy have indicated higher survival rates than have previously been seen.
In , an international effort  identified seven prognostic factors that accurately predict the success rate of conventional treatment in people with locally extensive or advanced stage Hodgkin's lymphoma. Freedom from progression FFP at 5 years was directly related to the number of factors present in a person. More recently, use of positron emission tomography PET early after commencing chemotherapy has demonstrated to have powerful prognostic ability. This prognostic power exceeds conventional factors discussed above.
Several trials are underway to see if PET-based risk adapted response can be used to improve a persons outcomes by changing chemotherapy early in people who are not responding. Unlike some other lymphomas , whose number of new cases per year increases with age, Hodgkin's lymphoma has a bimodal curve for the number of cases; that is, it occurs most frequently in two separate age groups, the first being young adulthood age 15—35 and the second being in those over 55 years old although these peaks may vary slightly with nationality.
The annual number of cases of Hodgkin's lymphoma is 2. In , globally it resulted in about 18, deaths down from 19, in The number of cases of Hodgkin's lymphoma is increased in people with HIV infection. Hodgkin lymphoma accounts for 0. In , approximately Canadians will be diagnosed with Hodgkin lymphoma, and will die of the disease.
Around 1, people were diagnosed with the disease in , and around people died in Hodgkin's lymphoma was first described in an report by Thomas Hodgkin , although Hodgkin noted that perhaps the earliest reference to the condition was provided by Marcello Malpighi in Of the seven cases, two were under the care of Richard Bright , one was of Thomas Addison , and one was of Robert Carswell. Hodgkin's report on these seven people, entitled "On some morbid appearances of the absorbent glands and spleen", was presented to the Medical and Chirurgical Society of London in January and was subsequently published in the society's journal, Medical-Chirurgical Society Transactions.
In , Samuel Wilks independently reported on a series of people with the same disease that Hodgkin had previously described.
Bright made Wilks aware of Hodgkin's contribution and in , Wilks published a second paper, entitled "Cases of enlargement of the lymphatic glands and spleen", in which he called the disease "Hodgkin's disease" in honor of his predecessor. Theodor Langhans and WS Greenfield first described the microscopic characteristics of Hodgkin's lymphoma in and , respectively. Tissue specimens from Hodgkin's seven people remained at Guy's Hospital for a number of years. Nearly years after Hodgkin's initial publication, histopathologic reexamination confirmed Hodgkin's lymphoma in only three of seven of these people.
Hodgkin's lymphoma was one of the first cancers which could be treated using radiation therapy and, later, it was one of the first to be treated by combination chemotherapy.

Age-adjusted and stage-adjusted modifications of this IPI are used for younger patients with localized disease. Shorter intervals of time between diagnosis and treatment appear to be a surrogate for poor prognostic biologic factors.
Dose-intensive therapies, infusional therapies, and stem cell transplantation consolidation are being explored in this high-risk group. The induction therapy did not alter 3-year relapse-free survival or OS when autologous stem cell transplantation SCT was employed.
Patients at high risk of relapse may be considered for clinical trials. Molecular profiles of gene expression using DNA microarrays may help to stratify patients in the future for therapies directed at specific targets and to better predict survival after standard chemotherapy. Patients who have DLBCL with coexpression of CD20 and CD30 may define a subgroup with a unique molecular signature, a more favorable prognosis, and possible therapeutic implication for the use of anti-CD30—specific therapy, such as brentuximab vedotin.
Patients with DLBCL who are event-free after 2 years have a subsequent OS equivalent to that of the age- and sex-matched general population. CNS prophylaxis usually with four to six injections of methotrexate intrathecally is recommended for patients with testicular involvement. Some clinicians are employing high-dose intravenous methotrexate usually four doses as an alternative to intrathecal therapy because drug delivery is improved and patient morbidity is decreased.
CNS prophylaxis for bone marrow involvement is controversial; some investigators recommend it, others do not. A retrospective analysis of patients with diffuse large cell lymphoma who did not receive prophylactic intrathecal therapy identified an elevated serum LDH and more than one extranodal site as independent risk factors for CNS recurrence.
Four to six of the IPI risk factors refer to the Prognosis section of this summary for more information and involvement of the kidneys or adrenal glands were used to define the high-risk group that might benefit from CNS prophylaxis. The addition of rituximab to cyclophosphamide, doxorubicin, vincristine, prednisone CHOP -based regimens has significantly reduced the risk of CNS relapse in retrospective analyses. Mediastinal lymphomas with features intermediate between primary mediastinal B-cell lymphoma and nodular-sclerosing HL are called mediastinal gray-zone lymphomas.
Patients are usually female and young median age, 30—40 years. Patients present with a locally invasive anterior mediastinal mass that may cause respiratory symptoms or superior vena cava syndrome. Uncontrolled, phase II studies employing dose-adjusted EPOCH etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab or R-CHOP rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone show high cure rates while avoiding any mediastinal radiation.
Posttreatment fluorine F fludeoxyglucose 18F-FDG positron emission tomography—computed tomography PET-CT scans are controversial; it remains unclear if PET scans can reliably identify patients who can take or omit radiation therapy consolidation. The only randomized trial showing an OS advantage for combined modality therapy was retracted. In situations where mediastinal radiation would encompass the left side of the heart or would increase breast cancer risk in young female patients, proton therapy may be considered to reduce radiation dose to organs at risk.
The natural history of follicular large cell lymphoma remains controversial.
While there is agreement about the significant number of long-term disease-free survivors with early-stage disease, the curability of patients with advanced disease stage III or stage IV remains uncertain. Some groups report a continuous relapse rate similar to the other follicular lymphomas a pattern of indolent lymphoma. This discrepancy may be caused by variations in histologic classification between institutions and the rarity of patients with follicular large cell lymphoma.
Treatment of follicular large cell lymphoma is more similar to treatment of aggressive NHL than it is to the treatment of indolent NHL. In support of this approach, treatment with high-dose chemotherapy and autologous hematopoietic peripheral SCT shows the same curative potential in patients with follicular large cell lymphoma who relapse as it does in patients with diffuse large cell lymphoma who relapse.

These lymphomas are usually of T-cell origin, often present with extranodal disease, and are found especially in the skin. The translocation of chromosomes 2 and 5 creates a unique fusion protein with a nucleophosmin-anaplastic lymphoma kinase ALK.

Patients whose lymphomas express ALK immunohistochemistry are usually younger and may have systemic symptoms, extranodal disease, and advanced-stage disease; however, they have a more favorable survival rate than that of ALK-negative patients. For patients with relapsed disease, anecdotal responses have been reported for brentuximab vedotin anti-tubulin agent attached to a CDspecific monoclonal antibody , romidepsin, and pralatrexate. ALCL in children is usually characterized by systemic and cutaneous disease and has high response rates and good OS with doxorubicin-based combination chemotherapy.
Types of stage 4 lymphoma
Patients with breast implant—associated ALCL may do well without chemotherapy after capsulectomy and implant removal if the disease is confined to the fibrous capsule, and no associated mass is present. Other extranodal sites include the palate, trachea, skin, and gastrointestinal tract. Hemophagocytic syndrome may occur; historically, these tumors were considered part of lethal midline granuloma. Cases with blood and marrow involvement are considered NK-cell leukemia.
A retrospective review of 1, early-stage patients stratified them into a low-risk group and high-risk group using stage, age, LDH, performance status, and primary tumor invasion.
