Activity of N-acetyltransferase in patients with malignant lymphomas

Activity levels of N-acetyltransferase and acetylation types in patients with malignant lymphomas, following sulfadimidine loading, were established. The ratio of "fast" and "slow" acetylators among patients with malignant lymphomas is shown to be similar to that in control group. The rate of acetylation in "slow"-acetylating patients, however, was higher than in healthy controls. A relationship of N-acetyltransferase activity, tumor progression and, to a considerable extent, effectiveness of therapy was shown.
