The use of single alkylating agents has produced objective responses in 60% of patients with a duration of less than 6 months. One of the alkylating agents (e.g., mechlorethamine, cyclophosphamide, or chlorambucil), or the antimetabolite methotrexate is the most frequently used. Single agents have not been shown to cure any patients, and insufficient data exist to determine if these agents prolong survival. Combination chemotherapy is not definitely superior to single agents. Even in stage IV disease, treatments directed at the skin may provide significant palliation.

A randomized study of 103 patients compared combined total-skin electron-beam radiation (TSEB) plus combination chemotherapy with conservation therapy consisting of sequential topical therapies.[1] In the latter group, combination chemotherapy was reserved for symptomatic extracutaneous disease or for disease refractory to topical therapies. Patients of any stage were eligible. Although the complete response rate was higher with combined therapy, toxic effects were considerably greater, and no difference was seen in disease-free or overall survival between the two groups.[1][Level of evidence: 1iiA]

Standard treatment options:[2]

1. Psoralen and ultraviolet A radiation (PUVA). Therapeutic trials with PUVA have shown a 62% to 90% complete remission rate with early cutaneous stages achieving the best responses. PUVA may be used in conjunction with systemic treatment. Maintenance therapy with PUVA is generally required to prolong remission duration.[3] PUVA combined with interferon-alpha-2a is associated with a high response rate.[4]



2. TSEB. Electron radiation of appropriate energies will penetrate only to the dermis, and the skin alone can be treated without systemic effects. This therapy requires an excellent radiation therapy facility with physics support, considerable technical expertise, and precise dosimetry. This therapy can produce excellent palliation and may be combined with systemic treatment.[5]



3. Local electron-beam radiation or orthovoltage radiation therapy may also be used to palliate areas of bulky or symptomatic disease.



4. Fludarabine, 2-chlorodeoxyadenosine, and pentostatin are active agents for mycosis fungoides (MF) and Sézary syndrome.[6-8]



5. Interferon-alpha alone or in combination with topical therapy, as evidenced in the ECOG-1495 trial.[7,9]



6. Denileukin diftitox (interleukin-2 fusion toxin) for CD25 and MF.[10,11]



7. Systemic chemotherapy: chlorambucil plus prednisone, mechlorethamine, cyclophosphamide, methotrexate, and combination chemotherapy. [1,12,13]



8. Topical mechlorethamine (nitrogen mustard). This form of treatment may be used palliatively or to supplement therapeutic approaches directed against nodal or visceral disease. The overall complete remission rate in 243 patients was 64% and was related to stage; as many as 35% of stage IV patients had complete responses. Treatments are usually continued for 2 to 3 years.[14,15]



9. Extracorporeal photochemotherapy alone [16-18] or in combination with TSEB.[19]



10. Serotherapy with monoclonal antibodies.[20,21]



11. Bexarotene, an oral or topical retinoid.[22,23]



12. Pegylated liposomal doxorubicin.[24]



13. Vorinostat, an oral histone deacetylase inhibitor.[25]

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage IV mycosis fungoides/Sezary syndrome. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
