[Successful treatment of adult T-cell leukemia with interferon-alpha-2b by systemic and local administration].
A 59 years old woman, born in Fukuoka Prefecture, was admitted to our hospital in Aug, 1988 because of diarrhea, fever and skin eruption. Physical examination revealed systemic lymphadenopathy and hepatosplenomegaly. The white blood cell count was 11,200/microliters with 28% atypical lymphocytes with convoluted nuclei. Mild anemia, thrombocytopenia and hypercalcemia were also observed. Antibody against the adult T-cell leukemia (ATL) associated antigen in serum was positive. OKT 4/8 ratio was high. A diagnosis of ATL was made. Because of the complications of pneumonia and herpes simplex, systemic chemotherapy was not given, and interferon (IFN)-alpha-2b was intramuscularly injected daily from Oct, 1988, resulting in the disappearance of atypical lymphocytes and improvement of skin lesions. The effect of IFN therapy lasted for three months, followed by increase of atypical lymphocytes. Although the patient became refractory to systemic IFN therapy, local injection of IFN into a buccal tumor infiltrated with atypical lymphocytes resulted in its regression of size. In spite of continued administration of IFN, the patient died of pneumonia in Jan, 1989.
