Objectives

I.  Determine if the addition of interferon alfa-2b to standard topical 
treatments for CTCL affects time to progression, overall response rate, and 
time to response.

II.  Determine the survival duration and toxic effects in patients with stage 
IB, IIA, and stage IIB CTCL mycosis fungoides (MF), and summarize toxic 
effects associated with the different topical treatments.

Expected Enrollment

315 eligible patients will be accrued over 3.5 years with 2 years of follow-up.

Outline

Patients are randomized into two groups.  One group receives either psoralen 
with phototherapy (PUVA), mechlorethamine, or total skin electron beam 
radiation (TSE).  All others receive one topical therapy plus interferon 
alfa-2b. 

Oral methoxsalen is given 1.5 to 2 hours before light therapy.  PUVA 
treatments are given 3 times a week beginning at a low dosage with gradual 
escalation in exposure depending on skin tone, ability to tan, type of 
phototherapy unit used, and the presence of redness at the time of each 
subsequent treatment.

If complete remission (CR) occurs, PUVA continues for 2 months at the dose and 
frequency at which clearing has occurred.  PUVA can then be tapered to 
maintenance which will be given once weekly for 4 weeks, then every 2 weeks 
for a maximum of 2 years.

Mechlorethamine is administered daily to skin for 4 to 6 weeks.  If skin 
biopsy is negative and lesions have disappeared, treatments will be reduced to 
once weekly, and maintained for 2 years.

TSE is delivered to the entire skin surface over 4 to 10 weeks in 20 to 40 
treatments.  Soles of the feet are treated separately in at least 20 
treatments over 4 to 10 weeks.

Interferon alfa-2b is given SC 3 times a week and continues for 2 years in the 
absence of disease progression or excessive toxic effects.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
