Abstract

Telomeres of tumor nuclei tend to form aggregates (TA). The same phenomenon was also observed in premalignant states. The aim of this study was to estimate TA formation in leukocytes of patients with non-Hodgkin lymphoma (NHL) at different disease stages (diagnosis, treatment, relapse, and remission). The peptide nucleic acid Telomere Kit was used to evaluate TA formation, using two-dimensional fluorescence microscopy. A higher rate of TA was found in all the NHL stages (including remission) than in the control group. Significantly higher TA formation was also observed in the relapse group, compared to the diagnosis group. It may be possible that patients with higher TA numbers are prone to relapse. From our previous results involving replication pattern, random aneuploidy rate, and (recently) TA formation, it can be concluded that the patients in remission are at higher risk of developing relapse than the normal population throughout their life span. The genetic instability parameters remain in the cells of these patients, who must continue to be monitored throughout their life.
