Brief Title: Robotic and Laparoscopic Total Gastrectomy With D2 Lymphadenectomy for Locally Advanced Gastric Cancer
Official Title: Safety and Feasibility Between Robotic and Laparoscopic Total Gastrectomy With D2 Lymphadenectomy for Locally Advanced Gastric Cancer:A Prospective Cohort Study
Study ID: NCT03500471
Brief Summary: This study is a prospective, single-center, non-randomized, controlled, non-blind, and non-inferiority observation trial comparing robotic-assisted total gastrectomy with D2 lymph nodal dissection for locally advanced gastric cancer patients with laparoscopic procedure.
Detailed Description: Since Kitano firstly reported laparoscopy-assisted distal gastrectomy in 1994, the number of patients undergoing the laparoscopic procedure has gradually increased. The latest Japanese gastric cancer treatment guideline recommends laparoscopic gastrectomy (LG) as an optional treatment for cStage Ⅰ gastric cancer (GC). Based on the experience of early GC, most experienced surgeons have applied the laparoscopic procedure in patients with locally advanced gastric cancer (AGC) especially in east world like China, Japan and Korea. Though applying laparoscopic-assisted total gastrectomy (LATG) is much more difficulty than that of distal gastrectomy (DG), there are a mount of centers reported their experiences of this procedure. A meta-analysis including seventeen studies of 2313 patients (955 in LATG and 1358 in open total gastrectomy) demonstrated that LATG can have less blood loss, fewer analgesic uses, earlier passage of flatus, quicker resumption of oral intake, earlier hospital discharge, and reduced postoperative morbidity. However, the number of harvested lymph nodes, proximal resection margin, hospital mortality, 5-year OS and DFS were similar in both groups. According to the existing reports, LATG is technically safety and feasibility. To overcome the limitations of laparoscopic surgery, robot systems have been introduced to treat GC providing technical advantages since Hashizume firstly reported. Yoon and Son respectively compared robot-assisted total gastrectomy (RATG) with LATG, they drew a common conclusion that the number of dissected lymph nodes and postoperative complications were similar in both groups. But Son found that the mean numbers of retrieved LNs along the splenic artery from RATG was higher than LATG (2.3 vs. 1.0, p = 0.013), as was also the case at the splenic hilum and artery (3.6 vs.1.9, p = 0.014). Regretfully, most of their reported cases were early gastric cancer (EGC). Other literatures reported AGC patients under RATG or LATG together with distal gastrectomy (DG), we haven't found any literature compare RATG with LATG alone for AGC retrospectively. Since most literatures are EGC patients and retrospectively researches, we can't insist that patients with AGC may benefit under RATG. Therefore, we launch this prospective, single-center, non-randomized, controlled, non-blind, and non-inferiority observation trial comparing RATG for locally advanced gastric cancer patients with LATG.In the process of research,it will be divided into two groups according to the willing of patients or their legal representatives who choose one of the two procedures(RATG or LATG) to cure GC.The primary objective of this study is to assess whether RATG is comparable to laparoscopic approach in terms of overall postoperative morbidity rates. The secondary research objectives are to compare robotic with laparoscopic approach in terms of surgical outcomes, postoperative recovery courses.
