Methods: Thirty-two premenopausal patients diagnosed and treated from 2003 to 2020 for borderline ovarian tumors were retrospectively evaluated. Results: The 32 borderline included 12 serous, 19 mucinous, and 1 endometrioid tumors, 2 of them were of stage more than I. The average age of the patients was 34.5 years (14–45), 22 were symptomatic, pain being the most frequent symptom (68.8%). 8 patients were operated on primarily by laparoscopy and 24 by laparotomy. In the laparoscopy group, median tumor diameter was smaller (7.5 versus 14.7 cm, p = 0.019) and surgeries were less extensive, without hysterectomy, as compared to the laparotomy group. There were 21 fertility-sparing surgeries, 7 patients attempted a subsequent pregnancy and in 6 cases a pregnancy with a healthy child was obtained (2 using assisted reproductive techniques). During the 7–108 months follow-up time, there were 3 relapses: 2 borderline tumors (treated surgically and desease free) and 1 carcinoma treated with surgery and chemotherapy that ended in death due to cancer. Discussion: In our study, only 6.25% of the borderline tumors were of stage more than I, whereas other studies report a higher proportion of more advanced stages (7.5–18.5%). As borderline ovarian tumors more often arise in young women, in whom malignancy is less common and who wish to preserve their fertility, their initial surgery is often laparoscopy. Conclusions: Borderline ovarian tumors have an excellent prognosis. Good results are provided in young patients wishing to preserve fertility.
