Abstract
Chromosome studies were carried out by G-banding technique on the bone marrow cells of 24 newly diagnosed, untreated Hodgkin's disease patients and 25 treated patients. Seven of these treated patients had also been studied at diagnosis. In the untreated group of patients, cytogenetic studies were carried out on stimulated peripheral blood lymphocytes in 11 patients and on skin fibroblasts in five. Of the 24 untreated patients, 14 showed normal diploid pattern, while 10 were seen with 8-30 per cent chromosomally aberrant cells in the bone marrow. The frequent anomalies were trisomy C/8 and trisomy 22 seen in 5 and 4 patients respectively. The cytogenetic picture of peripheral blood lymphocytes revealed normal diploid pattern in 7 patients; while 4 other patients showed abnormal clones with trisomy 21. The cultured skin fibroblasts represented normal diploid karyotypes. An altered karyotypic pattern was seen in the bone marrow of treated patients. In patients with abnormal karyotypes, the common anomalies were monosomy C, monosomy D/15 and trisomy 21. In patients which showed no involvement of the bone marrow by haematological parameters, chromosomally abnormal karyotypes were seen in the marrow. Thus, marrow involvement can be detected earlier cytogenetically.
