Popis: Sister chromatid exchange (SCE) frequencies were studied in lymphocytes from 45 patients with malignant lymphoma. Fifteen patients were untreated when studied. The mean SCE frequency for these patients was 8.70 +/- 0.99 per mitosis. The mean score for 35 controls was 4.37 +/- 1.19. SCE mean scores were significantly higher in the untreated patients than in the controls (p < 0.001). Nine patients were treated with radiotherapy alone. The mean SCE frequency (6.80 +/- 0.87) they demonstrated was significantly lower (p < 0.01) than that found in untreated patients. Twelve patients received cyclophosphamide 1 month before the study was started. They demonstrated a mean SCE frequency (12.00 +/- 1.31) significantly higher (p < 0.05) than that found in patients who had received regimens that did not contain cyclophosphamide (9.72 +/- 1.32). From these findings we suggest that untreated patients with malignant lymphoma have elevated SCE frequencies, which may be further increased by chemotherapeutic agents.
