Hodgkin's lymphoma is a cancer of the lymphatic system. The lymphatic system drains excess fluid from the blood and protects against infection. Hodgkin's lymphoma is different from other forms of
Cancer occurs when cells in the body (in this case a type of white blood cell called lymphocyte) divide without control or order. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to
malignant tumors, which can invade nearby tissue and can spread to other parts of the body. A
does not invade or spread.
The cause of Hodgkin's lymphoma is unknown. It is likely related to complex genetic and environmental factors that lead to alteration of the immune system. There are some compelling pieces of data to suggest that it is caused by a virus, and the Epstein-Barr virus (EBV) has been considered.
A risk factor is something that increases your chance of getting a disease or condition.
Risk factors include:
Ages: 15-40 and over 55
History of infectious
or infection with Epstein-Barr virus, the causative agent of mononucleosis
Weakened immune system, including infection with
or the presence of
Prolonged use of human growth hormone
Painless swelling of the lymph nodes in the neck, armpit, or groin
The doctor will ask about your symptoms and medical history, and perform a physical exam. In particular, the doctor will carefully examine your lymph nodes. Most enlarged or swollen lymph nodes result from infection, not lymphomas. If infection is suspected, you may be given medication and instructed to return for re-examination.
If swelling persists, your doctor may order a lymph node
. The biopsy results will show whether there is cancer, and if so, the type and extent of the cancer that is present.
Treatment of Hodgkin’s disease depends on the stage of the disease: how far the cancer has spread and what organs are affected. In general, this means that staging tests to evaluate the condition of the lymph nodes in the body, the liver, spleen, and bone marrow must be done.
—a type of x-ray that uses a computer to make pictures of structures inside the body; done to evaluate the lymph nodes
Blood tests—to establish the condition of the liver and blood
—an extremely sensitive way of evaluating the spread of the disease
Gallium scan—a test that uses a radioactive compound to scan and take pictures of your body
Abdominal surgery to remove the
the liver—much less common because of the accuracy of noninvasive scans
Hodgkin's lymphoma is generally considered one of the more curable forms of cancer. The two primary ways of treating this cancer are:
Chemotherapy and External Radiation Therapy
the use of drugs to kill cancer cells. Chemotherapy may be given in many forms including: pill, injection, and via a catheter. The drugs enter the bloodstream and travel through the body killing mostly cancer cells, but also some healthy cells.
radiation is directed at the tumor from a source outside the body to kill the cancer cells.
In many cases, both chemotherapy and radiation are used to cure a patient of Hodgkin’s lymphoma. The choice of treatments will be based on:
Extent of disease (the stage)
Location of the affected lymph node(s)
Many other patient-related features that your doctor will discuss with you
It is very important that you be seen by both the medical oncologist to discuss chemotherapy and the radiation oncologist to discuss the radiation therapy. It is not wise to see only one of these specialists since the best treatment results come from a discussion and integrated approach.
If the cancer does not respond to chemotherapy or radiation, the outcome is usually very poor. There are some treatment options available, including:
Bone marrow transplantation
—Bone marrow is removed, treated, and frozen. Large doses of chemotherapy and/or radiation therapy are then applied to kill the cancer cells. After treatment, the bone marrow is replaced via a vein. Transplanted bone marrow may be the patient's bone marrow that was treated to remove cancer cells or marrow from a healthy donor.
Peripheral blood stem cell transplantation
—Stem cells (very immature cells that produce blood cells) are removed from circulating blood before chemotherapy or radiation treatment and then replaced after treatment.
There are no guidelines for preventing Hodgkin's lymphoma because the cause is unknown.
