简要总结
Gastric cancer represents a great challenge for health care providers and requires a multidisciplinary context in which surgery plays a main role.
Minimally invasive surgery has been progressively developed, first with the advent of laparoscopy and more recently with the spread of robotic systems, but a number of issues are currently being debated, including the limitations in performing effective extended lymph node dissections and, in this context, the real advantages of using the robotic systems, the possible role for the Advanced Gastric Cancer, the reproducibility of completely intracorporeal techniques and the oncological results achievable during follow-up.
A multicenter study with a large number of patients is now needed to further investigate the safety and efficacy as well as long-term outcomes of robotic surgery, traditional laparoscopy and the open approach.
详细描述
Overall purpose:
The Overall purpose is to develop a multi-institutional database comprising information regarding surgical, clinical and oncological features of patients undergoing surgery for gastric cancer with robotic, laparoscopic or open approaches and subsequent follow-up at participating centers.
General study design:
The registry will be established by retrospectively identifying subjects with gastric cancer treated at the participating centers.
Information gathered will be obtained from existing data and records, diagnostic tests and surgical interventions.
