Abstract.Ørbo A, Rydningen M, Straume B, Lysne S. Significance of morphometric, DNA cytometric features, and other prognostic markers on survival of endometrial cancer patients in northern Norway.The objective of this study was to evaluate the prognostic value of nuclear morphometric features and DNA ploidy by flow cytometry next to depth of myometrial invasion and vascular invasion in endometrial cancer of all FIGO stages.A total of 123 women (103 FIGO stage I, eight stage II, and 12 stage III and IV) from northern Norway were studied. The follow-up period was between 7 and 19 years. The median age of patients was 62 years. The primary surgery was performed in the University Hospital of Tromsø or in the seven different reference hospitals in the northern part of Norway after an endometrial cancer diagnosis. The histologic, morphometric, flowcytometric and immunohistochemical investigations were based on archival paraffin-embedded material. The information regarding the follow-up data and clinical information were obtained from the medical records.Thirteen (10.6%) patients from the entire group (all stages) but only three (2.7%) of the FIGO stage I and II patients died from locally recurrent or metastatic disease. FIGO substage (P = 0.0006; odds ratio [OR] = 16.44, 95% confidence interval [CI] = 3.36–80.45), vascular invasion (P = 0.01, OR = 6.42, CI = 1.57–26.34) and nuclear size (P = 0.025, 0 R = 1.3, CI = 1.05–1.61) were independently correlated with recurrence in a multivariate analysis but histologic grade and DNA ploidy were not. Vascular invasion was poorly reproducible both between and within the same observer, however.In this retrospective study of all stages of endometrial carcinoma with long follow-up periods the primary tumor characteristics nuclear perimeter and FIGO stage were of prognostic significance in addition to the poorly reproducible vessel invasion.

Purpose A primary objective of the fifth National Wilms Tumor Study (NWTS-5) was to identify prognostic indicators for patients with favorable-histology Wilms' tumor. The prognostic significance of telomerase expression level in primary tumor samples was assessed. Patients and Methods A case-cohort study was conducted involving 291 NWTS-5 registrants. Telomerase activity was measured using the telomeric repeat amplification protocol (TRAP). Expression levels of TERT mRNA (encoding the telomerase catalytic component) and TERC/hTR (the telomerase RNA template) were measured using quantitative real-time polymerase chain reaction. Results After excluding samples because of lack of viable tumor, RNA degradation, or insufficient clinical information, 244 patients remained for the final analysis (96 with relapse and 148 without relapse). Univariate analysis revealed a positive correlation between relative risk (RR) of relapse and levels of TERT mRNA and TERC expression. For each doubling in TERT mRNA and TERC level, the RR increased by a factor of 1.16 (95% CI, 1.04 to 1.29; P = .01) and 1.35 (95% CI, 1.11 to 1.64; P = .003), respectively. The one third of patients whose tumors had the highest TERC expression level had an RR of 2.06 (95% CI, 1.14 to 3.70; P = .02) compared with patients with the lowest level. TERC expression level remained a significant prognostic indicator in a multivariate analysis adjusting for TERT mRNA, tumor stage, and patient age. TRAP level did not correlate with RR of relapse. Telomerase expression levels were not predictive of overall survival. Conclusion Telomerase RNA expression level may provide a clinically useful adjunct to the current risk classification schema for favorable-histology Wilms' tumor.
