ABSTRACT
Cytogenetic analyses were performed on 64 nonmalignant thyroid goiters (11 common and 53 multinodular goiters) after short-term culture. The majority of goiters (67%) were characterized by a normal karyotype, but in 5 common (45%) and 16 nodular (30%) goiters, small clones with various numerical and/or structural aberrations were found, in addition to many normal cells. Trisomy or tetrasomy 7 was the most frequent numerical aberration, seen in five cases. Deletion of 18p11 was found in four cases, and in three of them as the sole change. Selection and clonal evolution of aneuploid cells present in nonmalignant goiters could underlie progression into adenoma formation.
