Laparoscopic vs. open procedure for intermediate‑ and high‑risk endometrial cancer: a minimum 4-year follow-up analysis
Menée en Chine à partir de données 2010-2017 portant sur 201 patientes atteintes d'un cancer de l'endomètre à risque intermédiaire ou élevé de récidive (âge moyen : 53 ans ; durée de suivi : au moins 4 ans), cette étude compare les résultats oncologiques périopératoires et les complications postopératoires d'une chirurgie par voie ouverte et d'une chirurgie par laparoscopie
Résumé en anglais
Background: The long-term oncologic outcomes after laparoscopic and open procedures for patients with intermediate‑ and high‑risk endometrial cancer (EC) remain unclear. Accordingly, laparoscopy cannot still be recommended as the standard choice for intermediate‑ and high‑risk EC. This retrospective study aimed to assess the perioperative and long-term oncologic outcomes of laparoscopy and open surgery in patients with intermediate- and high‑risk ECs within a minimum 4-year follow-up.
Methods: We included 201 patients who underwent laparoscopic or open procedures for intermediate‑ and high‑risk EC between 2010 and 2017. Between-procedure comparisons of perioperative and oncological outcomes were performed using the independent t-test or Pearson’s chi-squared test and the Kaplan–Meier method, respectively.
Results: Finally, there were 136 intermediate‑ and 65 high‑risk endometrial tumors in the laparoscopic and open groups, respectively. There were no between-group differences in all baseline characteristics. Compared with the open group, the laparoscopic group had a significantly longer mean operating time (p = 0.005) and a lower mean estimated blood loss (EBL) (p = 0.031). There was a higher possibility of postoperative complication in the open group than in the laparoscopic group (p = 0.048). There were no significant between-group differences in pathological outcomes as well as the recurrence-free survival and overall survival rates (p = 0.626 and p = 0.148, respectively).
Conclusions: Among patients with intermediate‑ and high‑risk EC, laparoscopic surgery has an advantage over the open surgery in reducing EBL and the rate of postoperative complications without weakening the oncological control. There were no between-procedure differences in the recurrence-free and overall survival rates.
