Starting treatment for chronic lymphocytic leukaemia (CLL)

There are different treatment options for CLL. Your hospital team will discuss these with you and listen to your wishes.

If your team thinks it’s time to start treatment, they’ll explain the options open to you and what the risks are. It’s important you understand the options because you’ll be closely involved in any decisions about your treatment.

If you need support talk to your hospital team about treatment or anything else, contact our Support Service on 0808 2080 888 or [email protected]. We can’t give you medical advice, but we can support you to make sure your questions are answered, and your wishes heard.

What are first- and second-line treatments?

The first treatment you have after being diagnosed is called first-line treatment. If you have another period of treatment later, this is called second-line treatment.

Aims of first-line treatment

The aim of first-line treatment is to reduce the number of CLL cells and get control of the disease. This is called being in remission. Once you’re in remission, you may continue with treatment or go back on watch and wait. It depends on the treatment you’ve been having.

We have more information about CLL treatments. Your hospital team will discuss the options with you.

Second-line treatment

Most patients respond well to first-line treatment, but CLL can’t be cured and will almost always come back. This is called relapsing.

CLL often relapses slowly, and it may be several years before you need second-line treatment.

If you relapse, your hospital team will consider whether you should have the same treatment again, or a different one. This will depend on:

  • how long you’ve been in remission
  • how well your first-line treatment worked
  • the results of genetic tests
  • your overall health and fitness.

The aim of second-line treatment is to get you into remission again.

Your hospital team will explain the options and although they will make recommendations, they will also take your wishes into account.

Don’t be afraid to ask questions, such as how long the treatment will last, what the side effects might be, how often you would need to go to hospital, how the treatment would be given.

What if I relapse again?

If you relapse after a second treatment, you will have treatment again. This may have the same or different from the treatment you’ve had before. There are lots of treatments for CLL and your hospital team will advise you on the options.

"They told me CLL is treatable but not curable. That was a shock at first, but after a while, you take comfort that there are effective treatment options when you need them."

Clinical trials for CLL

If there is a clinical trial (study) available, your consultant might recommend that you consider this. Clinical trials are done for several reasons, including developing new treatment options and improving existing ones.

Taking part in a clinical trial has many advantages, such as the opportunity to have the newest available treatment which might not be available outside of the trial. You’ll also be very closely monitored and have detailed follow-up. But it does come with uncertainties, and you may prefer not to take part in one.

If you don’t want to be in a trial, or there isn’t a suitable trial available, you’ll be offered the best treatment available at that time for your individual condition.

We have more information about clinical trials. Our clinical trials support service offers personalised support to understand and access suitable clinical trials.
