title: [Epidemiological studies of adult T-cell leukemia virus in patients with adult T-cell leukemia (ATL) and ATL-related diseases in Hokkaido District of Japan].
abstract: Sera and peripheral blood lymphocytes in 40 clinical cases of adult T-cell leukemia (ATL) and 66 cases of mature T-cell malignancies in Hokkaido district, the most northern part of Japan, were examined for the infection with ATL virus (ATLV). All of the 40 ATL patients (100%) had antibodies to ATLV-associated antigen (ATLA) and 13 (19.7%) of the 66 patients with mature T-cell malignancies other than ATL were also positive for anti-ATLA. When the peripheral ATL lymphocytes were assessed after short time cultivation, both ATLA antigen and C type virus particles were detectable. In contrast to the high prevalence of ATLV antibodies in these patients, the positivity in 30,000 control individuals in this district was 0.73%. It was calculated that 8 patients of a 40,000 seropositive population are diagnosed annually as ATL in this particular northern part of Japan.
