What is Leukaemia and Lymphoma?

Chronic Lymphocytic Leukaemia (CLL) and Lymphoma (also called non Hodgkin’s lymphoma or NHL) are commonly referred to as blood cancer and are types of cancer that cause white blood cells to behave abnormally. In lymphoma the white blood cells form lumps in the lymph nodes and/or other parts of the body. In leukaemia cancer cells are found and accumulate in the bone marrow and blood.

CLL and NHL are more common in men than women with the average age at diagnosis being between 60 and 65 years of age.

In New Zealand NHL is the sixth most common cancer and the third most common cancer in children. More than 800 new cases of lymphoma are diagnosed each year with over 85% of these being NHL. CLL is the most common leukaemia, accounting for more than 30% of all leukaemias. More than 120 new cases of CLL are diagnosed each year.

Diagnosing CLL and NHL

Diagnosing CLL and NHL is a skilful process that requires a combination of tests too numerous to go into any detail here. Firstly, your doctor will want to talk to you about your general health, lifestyle choices and family history. Usually your doctor will take some blood tests, although these alone will not usually diagnose the disease, but will act as an indicator to keep testing. Other tests are likely to involve biopsies (small tissue samples) taken from the bone marrow and/or lymph nodes. Depending on the findings of some of these tests, your doctor may include x-rays like CT scans and/or a MRI.

Treatment of CLL and NHL

CLL usually develops and progresses slowly over many months or years and most people have no symptoms of their disease when they are first diagnosed. In these cases people often require no treatment for a long time, apart from regular checkups. Others may need to be treated soon after they are diagnosed.

If someone with lymphoma begins to have symptoms, or if their major organs or bone marrow becomes affected, they usually start treatment straight away. When deciding how to treat your lymphoma it is important to know how fast it is likely to grow and cause problems to your body. This is called the grade of your lymphoma. Some types of lymphoma grow slowly and cause few symptoms and may not need to be treated urgently; these are known as indolent lymphomas. Others grow more quickly and generally need to be treated soon after they are diagnosed. These are known as aggressive lymphomas.

Treatment for NHL usually involves chemotherapy and/or radiotherapy. Chemotherapy but not radiotherapy is often used to treat CLL. Stem cell transplantation, steroid therapy and immunotherapy (monoclonal antibodies) such as MabThera may also be used.

Chemotherapy

Chemotherapy is a treatment with one or a combination of anti cancer medicines that aim to destroy or control cancer cells and works by killing cells that divide rapidly, one of the main properties of cancer cells. This means that it also harms cells that divide rapidly under normal circumstances: cells in the bone marrow, digestive tract and hair follicles; this results in the most common side effects of chemotherapy – myelosuppression (decreased production of white blood cells), mucositis (inflammation of the lining of the digestive tract) and alopecia (hair loss).

Today chemotherapy is often combined with immunotherapy (although immunotherapy can also be used on its own). This gives improved results in delaying progression of the disease for many months or years and increasing overall survival.

MabThera is an immunotherapy treatment that targets B-cell lymphoma by mimicking the way that the body’s own immune system naturally defends itself. You might also hear it described as monoclonal antibody therapy.

    MabThera can be prescribed for the treatment of patients with:

  • Previously untreated or relapsed indolent non-Hodgkin’s lymphoma
  • Previously untreated aggressive non-Hodgkin’s lymphoma
  • Maintenance treatment of patients with indolent non-Hodgkin’s lymphoma
  • Previously untreated or relapsed chronic lymphocytic leukaemia


MabThera is funded for the first two points above and is also funded for NHL under Special Authority, otherwise patients have to pay for treatment themselves. MabThera is also an unfunded medicine for CLL, your Oncologist will be able to tell you what it may cost to be treated with MabThera.

Managing the side effects of Chemotherapy

One of the common side effects of chemotherapy is a low white blood cell count. White blood cells fight infection so when these are low you are at increased risk of developing an infection, which can be life threatening. This condition is called neutropenia. Neulastim is used following chemotherapy to increase the number of white blood cells. This can reduce your chance of developing infections that might require treatment with antibiotics and/or hospital stays. These complications of chemotherapy can mean delays in your treatment and affect how well your treatment works. Neulastim may also help to keep your chemotherapy treatment on schedule.
