Objective: To investigate the incidence of microsatellite instability (MI)
in cervical carcinoma and its relationship with clinicopathological charact
eristics. Study design: A retrospective study of 100 cases of cervical carc
inoma. Results: MI, defined as tumor-associated alterations in at least one
of five dinucleotide microsatellite markers examined, was detected in 25%
of the cervical carcinomas which were observed. There was a nonsignificant
trend towards MI occurrence in higher grade tumors, more advanced stage and
cases with poor clinical outcome. Conclusion: The results suggest that mic
rosatellite instability is present in a subset of cervical carcinoma and ma
y be an independent prognostic factor. Further research with more samples i
s required. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
