Sézary syndrome, classified under ICD-10 code C84.18, is a rare and aggressive form of cutaneous T-cell lymphoma (CTCL) characterized by erythroderma, lymphadenopathy, and circulating malignant T-cells. The treatment of Sézary syndrome typically involves a multidisciplinary approach, focusing on managing symptoms, controlling disease progression, and improving the patient's quality of life. Below is an overview of standard treatment approaches for this condition.

Treatment Modalities

1. Systemic Therapies

Systemic therapies are often the cornerstone of treatment for Sézary syndrome, especially in advanced cases. These include:

• Chemotherapy: Agents such as methotrexate, gemcitabine, and chlorambucil are commonly used. Chemotherapy can help reduce the tumor burden and control symptoms, although it may not lead to long-term remission[1].

• Targeted Therapy: Brentuximab vedotin, an antibody-drug conjugate, targets CD30-positive cells and has shown efficacy in CTCL, including Sézary syndrome. Other targeted therapies may include histone deacetylase inhibitors like vorinostat and romidepsin, which can help in managing the disease[1][2].

• Immunotherapy: Agents such as interferon-alpha and interleukin-2 can stimulate the immune system to fight the cancer. These therapies may be used alone or in combination with other treatments[2].

2. Phototherapy

• PUVA Therapy: Psoralen plus ultraviolet A (PUVA) therapy is a form of phototherapy that can be effective in treating skin manifestations of Sézary syndrome. It involves the administration of a photosensitizing agent followed by exposure to UVA light, which can help reduce skin lesions and improve symptoms[1].

• Narrowband UVB: This is another form of phototherapy that can be beneficial for patients with skin involvement, helping to alleviate symptoms and improve skin condition[2].
