Mycosis fungoides: management with topical nitrogen mustard.
The technique of treatment, response rate, freedom from relapse, survival, and complications of therapy in 123 patients treated with topical nitrogen mustard (HN2) for cutaneous mycosis fungoides (MF) at Stanford University Medical Center are reviewed. Patients were treated with HN2 in an aqueous or ointment base with equal efficacy. Response rates depended on the extent of skin involvement. In limited plaque (T1) disease, complete and overall response rates were 51% and 88%, respectively, while in generalized plaque (T2) disease they were 26% and 69%. No patients with tumorous involvement (T3) achieved complete skin clearance and all 13 of these patients developed progression of disease. Only two of nine patients with erythrodema (T4) achieved a complete response (CR), and both later relapsed. After achieving a CR, 40% of patients with T1 disease and 60% with T2 disease later relapsed; however, subsequent therapies, including repeat courses of topical HN2, often were successful in achieving later skin clearance. Overall, 42% of T1 patients and 31% of T2 patients were without evidence of MF at last follow-up. When death occurred, it was usually unrelated to MF in the T1 group. However, half of the deaths of patients with T2 disease were attributable to MF. Among the 22 patients with T3 or T4 disease, 80% of deaths were attributable to MF. The most common complication observed was a cutaneous hypersensitivity reaction, which occurred much more commonly with the aqueous than the ointment preparation. Fourteen patients (11%) developed subsequent cutaneous malignancies.
