369 Background: To investigate the oncological feasibility and technical safety of laparoscopic gastrectomy with D2 lymphadenectomy for advanced gastric cancer. Methods: 186 advanced gastric cancer patients treated by gastrectomy with D2 lymphadenectomy were eligible for inclusion including those with invasion into the muscularis propria, subserosa, and serosa without involvement of other organs, and stages N0–2 and M0. We retrospectively compared the short- and-long term outcomes between laparoscopic gastrectomy and open gastrectomy. Results: We analyzed short-term outcomes by comparing distal- with total gastrectomy results. We found no significant difference for distal gastrectomy for postoperative morbidity (laparoscopic vs. open: n = 4 (4.6%) vs. n = 1 (3.6%); p= 1.00). We also found no significant difference in postoperative morbidity for total gastrectomy (laparoscopic vs. open: n = 2 (4.0%) vs. n = 1 (4.0%); p= 1.00). No deaths occurred in any group. The entire cohort analysis revealed no statistically significant differences in overall- or recurrence-free survival between the laparoscopic and open groups. For overall survival, there were no significant differences between open and laparoscopic groups for clinical stage II or III ( p= 0.29 and 0.27, respectively), and for pathological stage II or III ( p= 0.88 and 0.86, respectively). For recurrence-free survival, there were no significant differences between open and laparoscopic groups for clinical stage II or III ( p= 0.63 and 0.60, respectively), and for pathological stage II or III (p = 0.98 and 0.72, respectively). Conclusions: Laparscopic gastrectomy for advanced gastric cancer compared favorably with open gastrectomy regarding short- and long-term outcomes. Clinical trial information: 160907.

Abstract Purpose By comparing short- and long-term outcomes following totally robotic radical distal gastrectomy (TRDG) and robotic-assisted radical distal gastrectomy (RADG), we aimed to assess in which modus operandi patients will benefit more. Methods From January 2015 to May 2019, we included 332 patients undergone RADG (237) and TRDG (95). Based on the propensity score matching (PSM), inclusion and exclusion criteria, 246 patients were finally included in the propensity score-matched cohort including RADG group (164) and TRDG group (82). We then compared the short- and long-term outcomes following both groups. Results Propensity score-matched cohort revealed no significant differences in both groups. Intra-abdominal bleeding, time to pass flatus, postoperative activity time, length of incision hospital stays, and stress response were significantly less in TRDG group than in RADG group. We observed 30 complications in RADG group while 13 complications in TRDG group. There were no significant differences in TRDG group and RADG group in terms of operation time, time for anastomosis, proximal resection, distal resection margin, number of lymph node resection, and total hospitalization cost. Both 3-year overall survival and 3-year disease-free survival were comparable in both groups. Conclusions TRDG is a safe and feasible modus operandi profiting from short- and long-term outcomes compared with RADG. As surgeons improving their professional skills, TRDG could serve as the standard procedure for distal locally advanced gastric cancer with D2 lymphadenectomy.

Abstract Background: peri-operative chemo-radiotherapy played important role in locally advanced gastric cancer. Whether preoperative strategy can improve the long-term prognosis compared with postoperative treatment is unclear. The study purpose to compare long-term oncologic outcomes in locally advanced gastric cancer patients treated with preoperative chemo-radiotherapy (pre-CRT) and postoperative chemo-radiotherapy (post-CRT). Methods: From January 2009 to April 2019, 222 patients from 2 centers with stage T3/4 and/or N positive gastric cancer who received pre-CRT and post-CRT were included. After propensity score matching (PSM), comparisons of local regional control (LC), distant metastasis-free survival (DMFS), disease-free survival (DFS) and overall survival (OS) were performed using Kaplan-Meier analysis and log-rank test between pre- and post-CRT groups.Results: The median follow-up period was 30 months. 120 matched cases were generated for analysis. Three-year LC, DMFS, DFS and OS for pre- vs. post-CRT groups were 93.8% vs. 97.2% (p=0.244), 78.7% vs. 65.7% (p=0.017), 74.9% vs. 65.3% (p=0.042) and 74.4% vs. 61.2% (p=0.055), respectively. Pre-CRT were significantly associated with DFS in uni- and multi-variate analysis. Conclusion: Preoperative CRT showed advantages of long-term outcome compared with postoperative CRT.

Abstract Background: The prediction effect of preoperative chemo-radiotherapy(CRT) is not high and difficult to guide individualized treatment. We explored a surrogate endpoint for long-term outcomes in locally advanced gastric cancer patients after preoperative CRT. Methods: From April 2012 to April 2019, 95 patients enrolled in 4 prospective studies with locally advanced gastric cancer who received preoperative concurrent radio-chemotherapy were included. All patients were stage T3/4, N+. Local control (LC), distant metastasis-free survival (DMFS), disease-free survival (DFS) and overall survival (OS) were evaluated. The clinicopathological factors related to the long-term prognosis were analysed by uni- and multivariant analyses. The downstaging depth score (DDS), a novel method of evaluating the CRT response, was used to predict long-term outcomes. Results: The median follow-up period for survivors was 30 months. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve predicted by the DDS was 0.728, which was better than that of pathological complete response (pCR), histological response and ypN0 (AUC= 0.634, 0.640 and 0.643, respectively). The DDS cut-off value was 4. pCR and ypN0 were associated with OS (p = 0.026, 0.049). Surgery and the DDS were correlated with DMFS, DFS and OS (p = 0.001, 0.000, and 0.000 and 0.009, 0.013, and 0.032, respectively). The multivariate analysis showed that the DDS was an independent prognostic factor of DFS (p = 0.021). Conclusion: The DDS, a simple, short-term indicator, seems to be a better surrogate endpoint than pCR, histological response and ypN0 for DFS.
