“…Literature reports dealing with genotoxic effects in peripheral leukocytes of healthcare workers handling antineoplastic agents are somewhat contradictory. Some studies have found an association between increase in sisterchromatid exchanges (SCE) [Sardas et al, 1991;GoloniBertollo et al, 1992], micronuclei (MN) [Yager et al, 1988;Anwar et al, 1994;Machado-Santelli et al, 1994], chromosome aberrations (CA) [Milkovic-Kraus and Horvat, 1991;Goloni-Bertollo et al, 1992;Grummt et al, 1993;Anwar et al, 1994], premature centromere division [Major et al, 1999], and DNA damage [Ü ndeger et al, 1999] and chronic exposure to these drugs. On the other hand, others have not observed any cytogenetic effect related to exposure [Benhamou et al, 1988;Cooke et al, 1991;Roth et al, 1994;Brumen et al, 1995;Ensslin et al, 1997;Lanza et al, 1999;Hessel et al, 2001].…”
