Introduction/Background*Radical surgery is the main treatment for Borderline Ovarian Tumors. Surgery includes hysterectomy, double adnexectomy, omentectomy and appendectomy if the histological line is mucinous.

Due to the excellent prognosis, some authors affirm that it is possible to perform a conservative surgery in young women who have not fulfilled their reproductive desire, without having repercussions in terms of overall survival.

The objective of the study was to know the treatment and the overall survival of the Borderline Ovarian Tumors in young women.

Methodology A retrospective cohort study was conducted. The study period was from January 2012 to January 2020. A total of 131 women with Borderline Ovarian Tumors were included in the study. Information was collected about: demographic data, diagnosis, type of surgery performed, disease-free survival, and overall survival. Two cohorts were established: conservative treatment (n = 37) vs radical treatment (n = 94).

Result(s)*131 women with a diagnosis of Borderline Ovarian Tumors were diagnosed, representing 16.7% of all the malignant ovarian tumors within this period (n = 784). 91.5% were diagnosed in Stage I according to the FIGO classification and the most histological line frequent was the mucinous (49.2%). The risk of global relapse was 6.2% and overall survival was 95.4%.

Regarding the group of patients who underwent conservative surgery, the risk of relapse was 13.5% (n = 5) compared to 3.2% (n = 3) in the group radical treatment, (p = 0.042).

The Overall survival was 100% in women with conservative surgery compared to radical surgery, 94.6%, (p = 0.130).

Conclusion*Borderline Ovarian Tumors present excellent prognosis, obtaining great positive results in overall survival regarding the performance of conservative surgery in young women with unfulfilled reproductive desire.
