Mycosis Fungoides and the Sézary Syndrome Treatment (PDQ®)

Health Professional Version

Stage II Mycosis Fungoides

No curative therapy exists for patients with stage II disease. The choice of initial palliative therapy is, therefore, dependent on the patient’s symptoms and the local expertise with each modality.

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 with 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]

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. Maintenance therapy with PUVA is generally required to prolong remission duration.[3,4] PUVA combined with interferon alpha-2a is associated with a high response rate.[5]
  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 a radiation therapy facility with physics support, considerable technical expertise, and precise dosimetry. The therapy can provide excellent palliation with complete response rates of as much as 80%.[6-9]
  3. Ultraviolet B radiation is under clinical evaluation.
  4. Symptomatic management with topical corticosteroids.
  5. Topical mechlorethamine (nitrogen mustard). Topical application of mechlorethamine has produced regression of cutaneous lesions with particular efficacy in early stages of the disease. The overall complete remission rate is related to skin stage; 25% to 75% of TNM classification T2, and as many as 50% of T3 patients have complete responses. Treatments are usually continued for 2 to 3 years.[6,10,11]
  6. Local electron-beam radiation or orthovoltage radiation therapy may also be used to palliate areas of bulky or symptomatic disease.[12]
  7. Interferon-alpha alone or in combination with topical therapy, as evidenced in the ECOG-1495 trial.[13]
  8. Bexarotene, an oral or topical retinoid.[14,15]
  9. Oral methotrexate (NCT00425555).[16]
  10. Pegylated liposomal doxorubicin.[17-19]
  11. Vorinostat or romidepsin or other histone deacetylase inhibitors.[20-22]
  12. Pralatrexate (folate analog).[23]
  13. Denileukin diftitox (interleukin-2 fused with diphtheria toxin).[24,25]

Current Clinical Trials

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