Staging and Treatment Guidelines

General Approach for Treating Non-Hodgkin's Lymphoma

Treatment for non-Hodgkin's lymphoma is highly specific for each patient and is determined by the classification and includes the following factors:

Stage
Grade
Histologic type (cellular structure)
Location
Other factors, such as blood levels of lactate dehydrogenase

Treatment for lymphomas has been primarily dependent on chemotherapy (particularly intensive regimens using several drugs) or a combination of chemotherapy and radiation. For advanced or refractory lymphomas and for relapse, patients may undergo bone marrow or stem cell transplantation. New treatments, especially those known as immunotherapies, or biological response modifier (BRM) therapies, are showing promise. Some experts recommend that patients ask their doctors about getting into well-designed clinical trials as early as possible.

Assessing Treatment Success

In assessing the success of a clinical trial, experts often refer to the tumor response. A complete response, for example, means that there is no longer any evidence at all of the disease by examination, blood tests, or x-ray studies. It does not necessarily mean, however, that the disease is cured. It may still recur later on.

In judging the success of a treatment for NHL, the most important criteria are overall survival and the duration of time until the disease progresses or the patient dies.

Early Stage Lymphomas (Stage I and Stage II)

In Stage I, lymphoma is found in only one lymph node area or in only one area or organ outside the lymph nodes. Either of the following indicates stage II:

Lymphoma is found in two or more lymph node areas on the same side of the diaphragm.
Lymphoma is found in only one area or organ outside the lymph nodes and in the lymph nodes around it. Other lymph node areas on the same side of the diaphragm may also have lymphoma.

Early Stage Indolent (Low-Grade) Lymphoma. Below are the general treatment options:

Radiation therapy. Radiation to local areas can achieve a cure in 40 - 50% of patients.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells.
Watchful waiting. Patients who choose watchful waiting must be aware of signs and conditions indicating the need for treatment. These include B symptoms, endangered organs, massive bulky tumors, or a steady progression that lasts at least 6 months.
Investigative treatments such conjugated and unconjugated monoclonal antibodies or radiation plus chemotherapy. In one study, a combination of therapies worked better than radiation alone.
