About

Prospective Multicenter Observational Study The study involves the consecutive inclusion of every patient with endometrial cancer undergoing staging surgical treatment using a robotic approach with the da Vinci SP platform.

Full description

The standard treatment for early-stage endometrial cancer is surgical staging, which includes total hysterectomy with bilateral salpingo-oophorectomy and surgical lymph node assessment.

The well-known advancements in minimally invasive surgery (MIS) have enabled laparoscopic and robotic surgical staging in gynecologic oncology. In the case of endometrial cancer, MIS is indeed the preferred surgical approach. Following the approval of the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) for gynecological procedures by the United States Food and Drug Administration in 2005, the use of robotic surgery for endometrial cancer has significantly increased, with favorable outcomes even compared to conventional laparoscopy.

The growing need for increasingly less invasive surgical options has led to the development of the possibility to perform endometrial cancer surgical staging through a single abdominal incision. Despite several attempts to apply single-incision techniques to laparoscopy in the context of endometrial cancer, the standard minimally invasive approach for hysterectomy remains the four-trocar laparoscopic technique. One of the main reasons is that introducing both the endoscope and instruments through a single incision creates internal and external conflicts between instruments and the surgeon's hands. The parallel placement of surgical instruments leads to clashes and restricts the range of motion.

To overcome these limitations, robotic technology may be applied to the single-incision technique. The recent introduction of single-port robotic surgery with the fourth-generation da Vinci® SP Surgical System represents a technological advancement. In fact, the system's flexible articulation of instruments allows for more effective manipulation while reducing instrument collisions. Moreover, the flexible camera provides a new operational angle in all directions.

The new da Vinci SP Surgical System (SP) received regulatory approval for use in gynecologic surgery in Italy in 2024. However, to date, studies in the literature on the use of the da Vinci SP robot in patients with endometrial cancer are limited due to the relatively small number of patients, single-center settings, and the retrospective nature of most studies.

Because of these limitations in the literature, definitive evidence is still lacking regarding the efficacy and safety profile of the da Vinci SP in surgical staging of early-stage endometrial cancer.

Based on these premises, the aim of this study is to clarify the outcomes associated with this minimally invasive robotic approach by reporting one of the first experiences of robotic surgical staging for endometrial cancer using the new da Vinci SP robotic platform.

The primary objective of the study is to evaluate the surgical efficacy profile of the minimally invasive robotic approach using the da Vinci SP platform for the surgical staging of endometrial cancer.
