Consult expert advice.

Treatment options depend on the stage of the disease.

  • Stage Ia-IIa
    • skin directed treatment options include topical steroids, topical chemotherapy (nitrogen mustard, carmustine), phototherapy (UVA, UVB)
  • Stage IIb
    • as for Stage Ia-IIa +/- localised radiotherapy
    • as for Stage Ia-IIa +/- biological response modifiers (retinoids/interferon)
    • total skin electron beam therapy
    • single or multi-agent chemotherapy
  • Stage III
    • options include:
      • extracorporeal photochemotherapy
      • single or multi-agent chemotherapy
      • as for Stage Ia-IIa +/- biological response modifiers, total skin electron beam therapy, localised radiotherapy
  • Stage IV
    • options include systemic chemotherapy; radiotherapy and palliative skin directed treatment

A systematic review concluded (1):

  • lack of high-certainty evidence to support decision making in the treatment of MF
  • PUVA is commonly recommended as first-line treatment for MF, and we did not find evidence to challenge this recommendation
  • absence of evidence to support the use of intralesional IFN-alpha or bexarotene in people receiving PUVA and an absence of evidence to support the use of acitretin or ECP for treating MF

NICE state that (2):

  • chlormethine gel is recommended as an option for treating early stage (stage 1A, 1B, and 2A) mycosis fungoides-type cutaneous T-cell lymphoma (MF-CTCL) in adults

Notes (3):

  • mechlorethamine (also known as chlormethine) or nitrogen mustard (NM) has a primary role in the early stages of the skin-limited disease and has been studied for its efficacy in MF since 1959
  • NM is a topical chemotherapeutic alkylating agent that affects rapidly dividing cells
    • gel formulation is associated with irritation, hyperpigmentation, pruritus, erythema, and contact dermatitis
