Patients are treated with Chlormethine gel (CL) gel. In case of any skin drug reaction, allergic test will be carried out. Patients not allergic to CL gel will continue at reduced application frequency, with the addition of topical steroid if necessary.

Adult patients with early stage MF-CTCL (stage IA-IB) will be eligible for this study. A total of 100 early stage MF-CTCL patients diagnosed in the past year will be enrolled.

Treatment with CL gel will be applied once daily to all skin areas affected by MF-CTCL and, for 8 weeks, one selected skin area unaffected by MF-CTCL (0.5% body surface area) until treatment response (complete response), study treatment duration completed (56 weeks), progression, or another withdrawal criterion is met.

Depending on the type of skin drug-related reaction (if any) occurring after application of CL gel, this study will categorize patients into three different groups corresponding to three different treatment patterns:

* Group A: Patients with no skin drug reaction with CL gel application
* Group B: Patients developing a skin drug reaction of any grade with CL gel application, not due to allergic reaction to CL gel, will continue treatment at reduced application frequency
* Group C: Patients from Group B unable to tolerate reduced CL gel application frequency will apply a potent topical steroid twice daily in addition to CL gel applied every other day

REACH: Study to Determine the Aetiology of Chlormethine Gel Induced-skin Drug Reaction in Early Stage Mycosis Fungoides Cutaneous T Cell Lymphoma (MF-CTCL)

Study to Determine the Aetiology of Chlormethine Gel Induced-skin Drug Reaction in Early Stage Mycosis Fungoides Cutaneous T Cell Lymphoma (MF-CTCL)

The response status - complete response (CR), partial response (PR), stable disease (SD) and disease progression (PD) - will be assessed using the global response assessment: skin, lymph nodes (not involved at entry), viscera (not involved at entry) and blood (absolute value CD4+CD7- and CD4+CD26- circulating population) as per EORTC-ISCL-USCLC guidelines
