There are two main sub-types of lymphoma:
HIV is a virus that attacks the immune system. Your immune system helps protect you from infection and disease. If your immune system is damaged by HIV, you are more likely to catch infections and to develop illnesses such as lymphoma.
People with HIV do not always develop lymphoma. But if you have HIV, you have a higher risk of some types of lymphoma. This includes Hodgkin lymphoma and some types of NHL.
The main types of NHL that affect people with HIV are:
- diffuse large B-cell lymphoma (DLBCL)
- Burkitt lymphoma (BL)
- primary central nervous system lymphoma (PCNSL).
These types of lymphoma also affect people without HIV.
If you are having tests to diagnose lymphoma, your doctor will ask you if they can take a blood sample to check for HIV too. Knowing whether you have HIV will help your doctors plan safer and more effective treatment for you.
This might mean you find out that you have HIV and lymphoma at the same time. This can be a lot to take in. You will be given information about both conditions and how they are treated.
You may be asked to make decisions about having treatments. You will meet some doctors and nurses who specialise in lymphoma, and others who specialise in HIV.
Your lymphoma doctors and HIV doctors will work together to plan your treatment. This may mean you have to travel to a hospital that treats both HIV and lymphoma.
Your lymphoma doctor will explain your treatment plan and you will make a decision together about treatment. They can also talk to you about possible ways to preserve your fertility.
Different types of lymphoma are treated in slightly different ways, but the main treatment is usually chemotherapy with steroids. For some types of lymphoma, you will also have a type of targeted therapy drug. Some people will have radiotherapy to treat an area of lymphoma.
If there are no signs of lymphoma after treatment, this is called remission. If lymphoma comes back, this is called recurrence or relapse.
People with HIV usually have the same lymphoma treatment as people who do not have HIV. But there can be a higher risk of some side effects. To reduce this risk and make lymphoma treatment as effective as possible, you will have treatment
- to control the HIV
- to prevent infections.
There is no cure for HIV, but anti-retroviral drugs help keep HIV under control. You take these drugs as tablets every day for the rest of your life. They may also be called combination therapy or HAART.
If you are not taking anti-retroviral drugs already, your doctor will talk to you about starting them. If the HIV is treated with these drugs, lymphoma treatment is more effective and you are less likely to have side effects.
Sometimes your HIV doctor will change your anti-retroviral drugs. This is because some of them can react with cancer treatments.
Treatment to prevent infections
Some lymphoma treatments affect the immune system and increase your risk of infections. You may have treatment to prevent infections, such as:
- anti-viral medicines
- anti-fungal medicines.
- Treatment to prevent infections is called prophylaxis.
You may also have a drug called G-CSF. You have it as a small injection under the skin. GCSF encourages your body to make more white blood cells. This helps increase the number of infection-fighting cells in your blood.
Most people have chemotherapy for lymphoma as an outpatient. Usually, you have a combination of chemotherapy drugs. The drugs are usually given as liquids into a vein (intravenously), or as tablets. Some people also have a targeted therapy drug along with chemotherapy.
With some types of lymphoma, there is a higher risk the lymphoma will spread to the brain. You may be given chemotherapy into the spinal fluid to reduce this risk. This is called intrathecal chemotherapy. This can also be used to treat lymphoma that is already affecting the brain.
Chemotherapy may affect how well your immune system is working for a while. This is a common side effect. It happens because the chemotherapy reduces the number of infection-fighting white blood cells in your blood.
Temporarily having a low number of white blood cells should not affect how well the HIV is controlled. But it can increase your risk of getting other infections. You will have regular blood tests and check-ups throughout your chemotherapy. You will be given contact details for your hospital before you start treatment.
If you have any signs of infection during chemotherapy, it is very important to contact the hospital for advice immediately.
Sometimes, your doctor will reduce your dose of chemotherapy or change the drugs you are given. This is usually only if there is a risk of serious side effects.
Steroids are drugs that are often given with chemotherapy to treat lymphoma. They help make chemotherapy more effective. They also help you feel better and can make you feel less sick.
Targeted therapies recognise and target specific proteins on the lymphoma cells. They also encourage the body’s immune system to attack and destroy the lymphoma cells.
The main type of targeted therapy used to treat lymphoma is a drug called rituximab.
You may have rituximab with chemotherapy and steroids. Sometimes it is given alone as the main treatment for lymphoma.
You may be more likely to get infections while you are having rituximab. You will have regular blood tests and check-ups throughout your treatment.
If you have any signs of infection during treatment, it is very important to contact the hospital for advice immediately.
Everyone has their own way of dealing with illness. You may have a lot of different emotions. This is normal. You may find it helpful to talk with family and friends or your doctor or nurse.
