  • Title: [Karyotype of peripheral blood lymphocytes in patients treated for Hodgkin disease].
    Author: Cappelaere P, Lai JL, Caty A, Deminatti M, Demaille MC.
    Journal: Bull Cancer; 1983; 70(1):31-9. PubMed ID: 6839032.
    Abstract:
    Peripheral lymphocyte chromosomes were analyzed in 55 consecutive patients with complete remission after treatment for Hodgkin's disease. In 8 patients, observed metaphases were too few in number. The other 47 patients, 29 men and 18 women, had been off all therapy for 53 months (median 41, ext. 1 to 250 months). The mean interval since the diagnosis was 78 months (median: 73 months) and the mean age at the time of chromosome analysis was 38 years (median: 34, ext. 10-78 years). No patient had either a preleukemic syndrome or leukemia. In contrast to karyotypes in normal controls and previously untreated patients, abnormal cells, hypodiploid, hyperdiploid and tetradiploid cells were more frequent. But neither monosomy 5 or 7 nor trisomy 8 were observed. Intrachromosomal rearrangements (gaps, breaks...) were significantly more frequent (12% vs 5% in untreated patients) particularly on chromosomes 1 and 2. Interchromosomal rearrangements were also numerous (1,25%) but no cells showed any specific translocation for malignant hemopathy. Chromosomal aberrations do not seem closely associated with treatments but influenced by the post-diagnosis interval and the factors present at the time of primary treatment.
