Burkitt Lymphoma

Burkitt lymphoma is a rare, fast-growing cancer that starts in immune cells called B-lymphocytes. It is a type of non-Hodgkin lymphoma. This aggressive cancer can affect different parts of the body, including the jaw, abdomen, or central nervous system, depending on its type. Though aggressive, it is often curable with intensive treatment.

What is Burkitt Lymphoma?

Burkitt lymphoma is a rare and aggressive cancer that originates in B-lymphocytes, which are a type of white blood cell in your immune system. It is considered one of the fastest-growing human cancers. This condition is a specific form of non-Hodgkin lymphoma and is categorized into three main types based on where it occurs and its associated risk factors.

Your lymphatic system is a vital part of your immune system, made up of tissues and organs like lymph nodes, spleen, and bone marrow. B-lymphocytes (B cells) are immune cells that normally help fight infections. In Burkitt lymphoma, these B cells grow out of control, forming tumors that can rapidly spread throughout the body. There are three main types of Burkitt lymphoma. The "endemic" (African) type is most common in children in Africa and often affects the jaw or facial bones. The "sporadic" (non-African) type occurs worldwide, affecting children and young adults, and usually starts in the abdomen (belly). The third type is "immunodeficiency-related" Burkitt lymphoma. This type affects people with weakened immune systems, such as those with HIV/AIDS or individuals who have received an organ transplant. All types are aggressive, meaning they grow and spread quickly, but they are often curable with modern intensive treatments. (MedlinePlus, Mayo Clinic)

Symptoms

Symptoms of Burkitt lymphoma often appear quickly and can include rapidly growing lumps, fever, night sweats, and unexplained weight loss. The specific symptoms you experience depend on where the cancer starts and spreads in your body, commonly affecting the jaw, abdomen, or central nervous system.

One of the most noticeable signs of Burkitt lymphoma is the rapid growth of tumors. These tumors can appear as swollen lymph nodes (small, bean-shaped glands) in your neck, armpits, or groin. The speed at which these lumps grow is a key characteristic of this cancer. Many people with Burkitt lymphoma also experience general symptoms, sometimes called "B symptoms." These include persistent fever without a clear cause, drenching night sweats that soak your clothes and bedding, and unexplained weight loss. For example, you might lose a significant amount of weight without trying to diet or exercise more. Specific symptoms vary by the type and location of the lymphoma. In the endemic type, a common symptom is swelling of the jaw or other facial bones. The sporadic type often causes abdominal pain, swelling, or a feeling of fullness in the belly. If the cancer spreads to the central nervous system (your brain and spinal cord), you might experience headaches, vision changes, or weakness. (MedlinePlus, Mayo Clinic)

Causes & risk factors

Burkitt lymphoma is primarily caused by a specific genetic change in B-lymphocytes. Certain factors increase your risk of developing this cancer, including infection with the Epstein-Barr virus (EBV), malaria, and conditions that weaken your immune system, such as HIV/AIDS.

The underlying cause of Burkitt lymphoma is a genetic mutation (change) within the B-lymphocytes. Specifically, it involves a rearrangement of the MYC gene, which leads to uncontrolled cell growth. This genetic change is not inherited but happens during a person's lifetime. Several risk factors are strongly linked to developing Burkitt lymphoma. The Epstein-Barr virus (EBV), a common virus that causes mononucleosis, is a significant risk factor, especially for the endemic type. In fact, nearly all cases of endemic Burkitt lymphoma are associated with EBV. (MedlinePlus, Mayo Clinic) Malaria, a serious mosquito-borne disease, is another important risk factor for the endemic type, particularly in regions where both malaria and EBV are common. Additionally, having a weakened immune system significantly increases the risk of immunodeficiency-related Burkitt lymphoma. This includes people with HIV/AIDS or those who take medications to suppress their immune system after an organ transplant. (MedlinePlus, Mayo Clinic)

How it's diagnosed

Diagnosing Burkitt lymphoma typically involves a biopsy, where a small tissue sample is taken from a suspicious tumor for examination. This is often combined with imaging scans to locate tumors and assess their spread, along with blood tests to evaluate your overall health and organ function.

The most crucial step in diagnosing Burkitt lymphoma is a biopsy. This procedure involves a doctor removing a small piece of tissue from a suspected tumor, a swollen lymph node, or other affected areas like the bone marrow or spinal fluid. A specialist then examines this tissue under a microscope to confirm the presence of Burkitt lymphoma cells and determine its specific type. (MedlinePlus, Mayo Clinic) To understand the extent of the cancer, doctors use various imaging tests. These may include computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, and positron emission tomography (PET) scans. These scans help locate tumors throughout your body, assess their size, and check if the cancer has spread to other organs or the central nervous system. Blood tests are also performed to check your general health, assess organ function, and look for any signs of infection. If there's a concern about central nervous system involvement, a lumbar puncture (spinal tap) might be done to collect a sample of cerebrospinal fluid for analysis. These comprehensive tests help doctors accurately diagnose the condition and plan the most effective treatment. (MedlinePlus, Mayo Clinic)

Treatment options

Treatment for Burkitt lymphoma primarily involves intensive chemotherapy, a powerful drug regimen designed to kill rapidly growing cancer cells. Due to the aggressive nature of this cancer, treatment is typically started quickly and may also include therapies to prevent or treat spread to the central nervous system.

Because Burkitt lymphoma grows very quickly, treatment usually begins soon after diagnosis. The main treatment is intensive chemotherapy, which involves using strong anti-cancer drugs, often in combination. These drugs are given to destroy cancer cells throughout your body. The specific chemotherapy regimen will depend on the type of Burkitt lymphoma and how far it has spread. (MedlinePlus, Mayo Clinic) For many people, especially children, chemotherapy is highly effective at curing Burkitt lymphoma. The treatment often includes multiple cycles of different chemotherapy drugs. Sometimes, chemotherapy drugs are given directly into the spinal fluid (intrathecal chemotherapy) to prevent or treat cancer spread to the central nervous system (brain and spinal cord). This is a common approach because Burkitt lymphoma has a tendency to affect this area. (Cochrane Library) In some specific situations, other treatments like radiation therapy or surgery might be considered. However, chemotherapy remains the cornerstone of treatment for Burkitt lymphoma. Your medical team will tailor the treatment plan to your individual needs, aiming to eliminate the cancer cells while managing potential side effects. (MedlinePlus, Mayo Clinic)

Recovery & outlook

Despite its aggressive nature and rapid growth, Burkitt lymphoma often has a good outlook, especially in children, due to significant advancements in intensive chemotherapy. Many people achieve a full recovery, highlighting the importance of early diagnosis and prompt, comprehensive treatment to improve chances of a cure.

The outlook for people with Burkitt lymphoma has improved dramatically over the years with modern medical advancements. While it is a very aggressive cancer, it is also highly responsive to intensive chemotherapy. This means that many people, particularly children, can achieve a cure. (MedlinePlus, Mayo Clinic) Early diagnosis and immediate, aggressive treatment are crucial factors in achieving a positive outcome. The goal of treatment is to eliminate all cancer cells from the body. After completing treatment, you will need regular follow-up appointments and tests to monitor for any signs of the cancer returning. This ongoing monitoring helps ensure long-term health. It is important to discuss your specific prognosis and recovery plan with your healthcare team. They can provide the most accurate information based on your individual situation, including the type of Burkitt lymphoma, how far it has spread, and your response to treatment. (Cochrane Library)

When to see a doctor

You should see a doctor promptly if you notice any rapidly growing lumps, especially in your jaw, neck, armpit, or groin. Also seek medical attention for persistent fever, drenching night sweats, unexplained weight loss, or severe abdominal pain, as these could be signs of Burkitt lymphoma or another serious condition.

If you or a loved one experience any new, quickly enlarging lumps, particularly in areas like the jaw, neck, armpit, or groin, it is important to get them checked by a doctor without delay. The rapid growth of these lumps is a key characteristic that warrants immediate medical evaluation. Additionally, be aware of general symptoms that persist or worsen. These include fevers that don't go away and have no clear cause, night sweats so severe they soak your clothing and bedding, or significant weight loss that you cannot explain. These symptoms, especially when combined, should prompt a visit to your doctor. Severe or worsening abdominal pain, swelling in the belly, or a feeling of fullness after eating only a small amount can also be concerning signs, particularly for the sporadic type of Burkitt lymphoma. While these symptoms can be caused by many less serious conditions, it is always best to have them evaluated by a qualified clinician to rule out serious illnesses like Burkitt lymphoma.

Frequently asked questions

Are there different stages of Burkitt lymphoma?

Yes, like many cancers, Burkitt lymphoma is staged to describe how far it has spread. However, due to its aggressive nature, it is often treated with intensive, multi-drug chemotherapy regardless of the initial stage, as it can spread very quickly.
