Supervivencia de cáncer cervicouterino escamoso y adenocarcinoma en pacientes atendidas en el Instituto Nacional del Cáncer, 2009-2013

Introduction

Cervico-uterine cancer is the fourth most common type of cancer in women worldwide, with an estimated incidence of 528,000 new cases annually (2012). Around 1,000 new cases were registered in Chile during 2008. The mortality rate for 2008 was 7.5 per 100,000 women.

Objective

To report on the overall survival of patients with a diagnosis of cervico-uterine cancer treated in the National Cancer Institute between 2009 and 2013.

Materials and methods

A case series study using the records and Hospital Cancer Registry Software (2011). All patients belonging to the Salud Metropolitano Norte, O‘Higgins and Maule Health Service diagnosed with cervico-uterine between the years 2009 and 2013 were identified. The variables taken into account for the analysis of survival were time zero, date of diagnosis by means of biopsy, and as event, the date of death. An analysis of survival according to histology and stages was performed using the Kaplan Meier method. The survival curves were compared using the Log-rank test. A confidence level of 95% was used.

Results

The overall survival at 5 years was 67.05%. According to histology, the overall survival at 5 years was 67.33% for squamous cell, and 67.13 for adenocarcinoma. The overall survival according to stage was: 90.40% stage I, 77.8% stage II, 47.4% stage III and 26.45% stage IV.

Conclusion

The calculated survival curves in this study are similar to the results achieved internationally in developed oncology centres. There is no statistically significant difference with the histology type.
