INTRODUCTION AND OBJECTIVES
Ovarian cancer is the fourth most frequently diagnosed gyneacological cancer in our country,
yet it carries the highest mortality rate among them. Factors modifying tumor survival have been
identified: age, tumor staging at diagnosis, histological type, and grade, as well as complete
cytoreduction at the time of surgery. The main objective of this study is to understand the
survival of women diagnosed and treated for epithelial ovarian cancer at Dr. Balmis University
General Hospital, as well as to identify factors that determine a higher survival rate in our
setting.
MATERIAL AND METHODS
A retrospective observational cohort study was conducted by analyzing patients diagnosed and
treated for ovarian cancer between 2000 and 2017 at Dr. Balmis University General Hospital.
The following variables were obtained through the review of the Orion Clinic digital medical
records: age, body mass index, associated comorbidities, initial symptom, CA125 (U/mL) value
at diagnosis, histological type, and grade, TNM staging, treatment received, type of surgery, and
months of survival. Statistical analysis was performed using R Commander Version 2.9-1. Kaplan-
Meier analysis was used to examine the relationship between survival and different prognostic
factors. A p-value was considered significant if less than 0.05.
RESULTS
A total of 223 women were included, of whom 131 (58.74%) were long-term survivors (survival
greater than 5 years) and 92 (41.26%) had survival of less than 5 years. When analyzing factors
related to survival among long-term survivors compared to those with survival of five years or less, long-term survivors had a lower mean age (55.58 vs. 65.42 years), lower CA-125 (U/mL)
value at diagnosis (131 vs. 573), a lower proportion of stages III/IV at diagnosis (55% vs. 76.1%),
a lower proportion of serous histological type (59.5% vs. 82.6%), high grade (63.4% vs. 92.4%),
and a higher proportion of optimal cytoreduction (72.5% vs. 19.6%).
CONCLUSIONS
More than half of women diagnosed and treated for epithelial ovarian cancer at Dr. Balmis
University General Hospital have long-term survival, exceeding 5 years. Long-term survivors are
identified as those who are younger, diagnosed at an early stage (I/II), have a non-serous
epithelial tumor of low grade, and achieve optimal cytoreduction.
