OBJECTIVE: To investigate survivals from cervical cancer, with special reference to effects of glandular histology and its influence on prognostic characteristics and management decisions. METHODS: Data on cervical cancers, diagnosed in 1984-2000, were obtained from the gynecologic oncology registry of hospitals of the University of Adelaide. Comparisons were made of disease-specific survival, age at diagnosis, diagnostic period, stage, grade, and primary course of treatment. RESULTS: The study included 544 squamous cell carcinomas, 43 adenosquamous carcinomas, five clear cell cancers, 136 other adenocarcinomas, and 19 cancers of "other" histological type. Overall survival was 72.2% at 5 years from diagnosis, decreasing to 67.5% at 15 years. Survival was lower for older ages, higher grades, and higher International Federation of Gynecology and Obstetrics stages, although equivalent for stages IIA and IIB. Unadjusted survivals varied by histological type (P = .001), with lower survivals suggested for adenosquamous and clear cell lesions and "other" histological types than for squamous cell carcinomas and other adenocarcinomas. After adjusting for age, stage, grade, and diagnostic period, adenocarcinomas had a higher case fatality than squamous cell lesions (relative risk 2.08, 95% confidence limit 1.35, 3.21), whereas the elevation in relative risk was lower and not statistically significant for a combined adenosquamous and clear cell category at 1.25 (0.69, 2.24). For stage II, both adenocarcinomas and the adenosquamous and clear cell group had lower survivals than squamous cell cancers. CONCLUSION: Relative to squamous cell carcinomas, adenocarcinomas and potentially adenosquamous cancers are becoming more common. This has implications for screening, treatment, and prognosis.
