[High-risk endometrial carcinoma in early stages: Hospital Italiano de Buenos Aires, oncological results].

Introduction: Endometrial cancer is the second most frequent gynecological tumor in Argentina, representing 6% of all cancers in women. The objective of this study is to evaluate the oncological and perioperative results in patients with high-risk endometrial cancer (HREC) limited to the uterus, treated at the Hospital Italiano de Buenos Aires, between January 2010-2018.

Methods: Retrospective cohort study that evaluated perioperative results, disease-free survival at 2, 4 years in patients with HREC.

Results: Of a total of 123 patients, 74 met the inclusion criteria. Serous tumors were the most frequent histological type, n=38 (51%), while dedifferentiated tumors were the least frequent, n=2 (3%). Of all the patients included, 56 (76%) received at least one adjuvant treatment. Taxol platinum-based chemotherapy was implemented in 28 patients (38%), while 24 (33%) received a combination of chemotherapy and radiotherapy. The median follow-up time was 2.9 years. Disease-free survival in patients with stage IA at 2 and 4 years was 71% (95% CI 55-82) and 63% (CI 46-76), respectively, while those with stage IB were 53 (95% CI 33-70) and 38 (95% CI 19-58). Regarding the surgical approach, no significant differences were found in disease-free or overall survival when comparing the laparoscopic with the laparotomy approach (p=0.06).

Conclusion: Only the FIGO stage showed an increased probability of death or relapse regardless of the type of adjuvant treatment and the type of surgery approach. Perioperative complications were similar in both approaches.
