Laparoscopic vs. robotic-assisted laparoscopy in endometrial cancer staging: large retrospective single-institution study

The aim of this study is to analyze and draw the potential differences between the robotic-assisted surgery (RS) and the laparoscopy (LPS) in endometrial cancer staging. In this single-institution retrospective study we enrolled 1,221 consecutive clinical stage I-III endometrial cancer patients undergone minimally invasive surgical staging. We compared patients treated by LPS and by RS, on the basis of perioperative and oncological outcomes (disease-free survival [DFS] and overall survival [OS]). A sub-analysis of the high-risk endometrial cancer population was performed in the 2 cohorts. The 2 cohorts (766 treated by LPS and 455 by RS) were homogeneous in terms of perioperative and pathological data. We recorded differences in number of relapse/progression (11.7% in LPS vs. 7% in RS, p=0.008) and in number of deaths (9.8% in LPS vs. 4.8% in RS, p=0.002). Whereas, univariate and multivariate analyses according to DFS and OS confirmed that the surgical approach did not influence the DFS or the OS. In the multivariable analysis the association of the age and grading was significant for DFS and OS. In the sub-analysis of the 426 high risk EC patients (280 in LPS and 146 in RS) the univariate and the multivariate confirmed the influence of the age in DFS and OS, independently of the minimally invasive approach. In our large retrospective analysis, we confirmed that the RS and LPS have similar efficacy and safety for endometrial cancer staging also for the high-risk endometrial cancer patients.

Clinical impact of surgical energy device (Caiman®) IN elderly patients with Endometrial Cancer (protocol ID: Cineca)

To investigate the clinical performance of the Caiman® energy device in class A radical laparoscopic hysterectomy (RLH) according to Querleu-Morrow classification, combined with bilateral salpingo-oophorectomy (BSO) and pelvic lymph node assessment in elderly patients with early-stage endometrial cancer (EC), specifically focusing on hemostatic effectiveness and safety. Single-institution, prospective observational study. Gynecologic Oncology Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Forty-three women over 65 years with FIGO stage IA or IB endometrioid EC were enrolled from September 2021 to August 2023. Use of Caiman® energy device in RLH combined with BSO and pelvic lymph node assessment in elderly patients. The primary endpoint was operative time, with secondary endpoints including perioperative outcomes and postoperative complications. Results demonstrated a median surgical time of 135 min, with no significant intraoperative complications attributed to the Caiman® device. Postoperative complications were minimal, with no severe complications (Grade 4 or 5) and a median hospital stay of two days. The study highlights the advantages of the Caiman® in enhancing surgical efficiency while minimizing risks for elderly patients, suggesting its potential for improving resource allocation and patient outcomes in oncologic surgery. The findings of this study suggest the feasibility of using the Caiman® device for surgical procedures in elderly patients with early-stage endometrial cancer. Future prospective randomized trials are needed to establish its efficacy compared to traditional surgical methods.

Predictive factors of surgical complications after pelvic exenteration for gynecological malignancies: a large single-institution experience

To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE). We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications. We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications. Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery.
