Abstract

Introduction: The survival of patients with Cervical Cancer is influenced by the clinical stages of the disease and its histology. The objective of this study was to establish survival in a group of patients from an oncology center in Cuenca-Ecuador.

Methods: It is a descriptive, retrospective, analytical study, in which information was collected from the medical records and physical records of the SOLCA - Cuenca medical system to establish Survival during the period 2009-2013. Demographic and clinical variables are described ( Type of histology and stage), Survival is compared between patients with these variables.

Results: 150 cases were included, mean age of 57.1 ± 14.0 years. The most prevalent marital status was “married” n = 75/150 (50%), of urban origin n = 83/150 (55.3%) from the province of Azuay (48.0%). The most prevalent histological type was epidermoid cancer (92%), 60% in clinical stage IIB. Mortality of 7 cases. Overall Survival (OS) 57.6 months; with a SE of 0.88 and a 95% CI with a range of 55.9 to 59.4 months. OS in stage IIB was 58.4 months (SE: 0.91; 95% CI: 56.63 - 60.20). In stage IIIB it was 56.3 months (SE: 1.85; 95% CI: 52.71 - 59.96), no statistical difference was found (P = 0.45). OS was higher in squamous cell carcinoma (Mean: 58.2 months; SE: 0.79, 95% CI: 57.70 to 59.81) in relation to the adenocarcinoma variant (Mean: 50.08 months; SE: 6.26; 95% CI: 37.81 to 62.36), with statistical significance (P= 0.045).

Conclusion: Overall survival was 57.6 months, with a survival difference for histological type, the longest being for squamous cell carcinoma 8 months less for adenocarcinoma. There were no differences between survival between clinical stages IIB and IIIB
