Background: Cutaneous T-cell lymphoma is a chronic peripheral lymphoma
in which aggressive combined therapy elicits high response rates but
does not improve survival. Photopheresis therapy has reportedly induce
d remissions and prolonged survival in patients with advanced disease.
Objective: We studied all patients who began photopheresis treatment
between February 1988 and July 1994 to determine whether we could conf
irm the remission rates of previous studies, to evaluate variables tha
t might predict a response, and to discover whether an accelerated del
ivery system would improve the remission rate or response time. Method
s: After an oral dose of methoxsalen was administered, a leukocyte-enh
anced quantity of blood was exposed to UVA radiation for 1.5 hours and
returned to the patient. With our accelerated system 6 x 10(9) cells
were irradiated in nine cycles. Treatments were given on 2 consecutive
days once a month. Results: Among 34 patients whose results could be
evaluated, the overall response rate (complete and partial remissions)
was 50%; most patients had mild side effects. All responders except o
ne had erythroderma. Responders had a decrease of 75% in mean skin sco
res, whereas nonresponders had an increase of 21%. Conclusion: Photoph
eresis appears to be effective for selected patients with erythrodermi
c cutaneous T-cell lymphoma, although we did not achieve as high a rem
ission rate as previously reported by others.
