Sezary syndrome

What causes Sezary syndrome?

Although a small percentage of cases of Sezary syndrome are associated with human T-lymphotropic viruses type 1 and type 2, the underlying cause of most cases is currently unknown. In people affected by the condition, the cancerous T-cells (also called Sezary cells) usually have one or more chromosomal abnormalities. These genetic changes are considered "somatic" because they are acquired during a person's lifetime, are not inherited and only affect the DNA of the cancerous cells. Although any chromosome can be affected, people with Sezary syndrome often have deletions of DNA from chromosomes 10 and 17 or duplications of DNA on chromosomes 8 and 17. However, it is unclear whether these alterations play a role in the development of the condition.

How is Sezary syndrome diagnosed?

A diagnosis of Sezary syndrome is often suspected in people with characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This may include:

  • A skin biopsy
  • A complete blood count
  • Peripheral blood smear
  • Immunophenotyping
  • T-cell receptor (TCR) gene rearrangement test
  • Flow cytometry

To learn more about the diagnosis of Sezary syndrome, including specific information about each of the tests listed above, please visit the National Cancer Institute's Web site. Simply click on the link and scroll down to the section entitled "tests that examine the skin and blood are used to detect (find) and diagnose mycosis fungoides and the Sezary syndrome"

Is Sezary syndrome inherited?

The underlying cause of Sezary syndrome is unknown in most cases. However, it generally occurs sporadically in people with no family history of the condition.

How can I learn about research opportunities for individuals with Sezary syndrome?

The U.S. National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. Currently, there are several clinical trials are identified as enrolling individuals with Sezary syndrome. To find these trials, click on the link above. After you click on a study, review its "eligibility" criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.

You can also contact the Patient Recruitment and Public Liaison (PRPL) Office at the National Institutes of Health (NIH). We recommend calling 1-800-411-1222 to speak with a specialist, who can help you determine if you are eligible for any clinical trials. If you are located outside the United States, and would like to be contacted via telephone, you will need to contact PRPL and provide your telephone number in full, including area code and international dialing prefix.

What is the long-term outlook for people with Sezary syndrome?

The long-term outlook (prognosis) for people with Sezary syndrome is generally poor. Sezary syndrome is difficult to cure. Treatment is usually palliative, with the intention of relief of symptoms and improvement in the quality of life. Median survival for patients with Sezary syndrome has been reported to be 2 to 4 years after development of the condition, although survival has improved with newer treatments. The disease-specific 5-year survival rate has been reported to be 24%.

How might Sezary syndrome be treated?

In general, there are six different treatment options available to people with Sezary syndrome. These include:

  • Photodynamic therapy
  • Radiation therapy
  • Chemotherapy
  • Other drug therapy (i.e. topical steriods, retinoids)
  • Biologic therapy
  • Targeted therapy
