Influence of 'nuclear' estrogen receptor content on prognosis of early stage carcinoma of the uterine body. A short-time follow-up

: Sixty-five patients with Stage I and II endometrial carcinoma were investigated. After a short-time follow-up (17-24 months) significant differences in frequency of relapses were observed between patients with tumors containing low amounts of estrogen receptor (ER less than 60 fmol/mg DNA) in the nuclear pellet, and those with tumors containing greater than 60 fmol ER/mg DNA (p = 0.01). Other prognostic factors showed no differences in frequency of relapses. In this small patient material with a short-time follow-up we therefore suggest that ER in the nuclear pellet may be an important prognostic factor.
