BACKGROUND: The incidence of adenocarcinoma of the uterine cervix is increasing. For better prognostic information, the authors studied all nonsquamous cell carcinomas (non-SCCs) in the Norwegian population over a total of 15 years. METHODS: All non-SCCs from three 5-year periods (1966-1970, 1976-1980, and 1986-1990) were reviewed and classified according to the World Health Organization classification system, and histopathologic and clinical parameters were registered. Tissue blocks were available from all patients. RESULTS: Of 505 patients, 417 had tumors classified as adenocarcinoma, and 88 had tumors classified as other non-SCC. The mean ages were 53 years and 52 years for patients with adenocarcinoma and non-SCC, respectively. Sixty-two percent of the staged patients had clinical Stage I disease according to the classification system of the International Federation of Gynecology and Obstetrics (FIGO). In univariate analyses, histology, architectural and nuclear grade, extension to the vagina or corpus uteri, tumor length (> 20 mm) or tumor volume (> 3000 mm(3)), infiltration depth (in thirds of the cervical wall), thickness of the remaining wall (< 3 mm), vascular invasion, lymph node metastases, treatment, and patient age were significant variables in patients with FIGO Stage I disease. Variables with no significance in patients with Stage I disease were number of mitoses, state of resection margins, infiltration to ectocervix, tumor thickness, lymphoid reaction, earlier or concomitant cervical intraepithelial neoplasia, stump carcinoma, DNA ploidy or DNA index, or time period. Multivariate analyses of patients with FIGO Stage I disease identified small cell carcinoma, corpus infiltration, vascular invasion, and positive lymph nodes as independent prognostic factors. CONCLUSIONS: Small cell carcinoma was the only histologic subgroup of independent importance for prognosis in patients with non-SCC of the uterine cervix. No significant difference between major subtypes of adenocarcinoma favored a simplified classification. Extension to the corpus in patients with early-stage disease was of independent significance and should be acknowledged in planning treatment. Copyright 2001 American Cancer Society.
