Telomerase activity has been implicated in the progression of various human
tumors. Our aim was to evaluate telomerase activity and to compare it with
histo-pathological factors in uterine endometrial carcinoma, to look for p
ossible correlations. Telomerase activity was measured by dilution analysis
using a PCR-based telomeric repeat amplification method and detected in 31
of 35 primary endometrial carcinoma tumor specimens. High telomerase activ
ity, detected after 100-fold dilution of extracts, was identified in 15 spe
cimens. There was no significant correlation between the positive telomeras
e activity and tumor surgical stage or histopathological factors. However,
high telomerase activity was significantly correlated with advanced surgica
l stage and with pelvic lymph node metastasis. Our findings suggest that an
increase in telomerase activity may be associated with tumor progression a
nd that its level may have a prognostic value in endometrial carcinoma. Int
