title: Multivariate-analysis of prognostic factors in 232 patients with clinical stage-I endometrial adenocarcinoma using the new figo surgical staging system.
abstract: A retrospective analysis is reported in 232 patients with clinical Stage I endometrial adenocarcinoma diagnosed between 1980 and 1988, treated with combined surgery and adjuvant irradiation. Tumors were restaged according to the FIGO (1988) surgical staging system (SSS) in order to assess the prognostic value of this revised classification and of the conventional clinico-pathological features (age, performance status, grade and depth of myometrial invasion). The 5-year relapse-free survival (RFS) and overall survival (OS) of the series was 85% and 90.8%, respectively. Both 5-year RFS and OS were not significantly different adopting the FIGO (1971) clinical Stage (Stage IA 93% and 88% vs Stage IB 88.5 and 82%. respectively) whereas they were significant by FIGO SSS (Stage IA 96% and 93% vs Stage IB 94% and 88.5% vs Stage IC 74% and 63%, respectively) (p=0.001 and p=0.0005, respectively). Other factors that significantly affected 5-year RFS or OS at univariate analysis were age (p=0.01 and p<0.0001, respectively), performance status (p=0.035 and p=0.001, respectively), grade (p=0.015 and p<0.0001, respectively) and myometrial invasion (p=0.0017 and p=0.0003, respectively). A multivariate analysis of these prognostic variables showed that FIGO SSS was the only significant and independent (p=0.01) indicator for recurrence. However, when therapy was added to the model, FIGO SSS failed to retain significance (p=0.11). Concerning OS age (p<0.0001), performance status (p=0.04) and FIGO SSS (p=0.05) were significant and independent prognosticators, also when therapy was included in the analysis. In conclusion, this study shows that the new FIGO SSS is a useful prognosticator as well as is age and performance status, in early Stage endometrial adenocarcinoma.
