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.

The Mean

Abstract Background The oncological outcomes of laparoscopic gastrectomy (LG) and open gastrectomy (OG) following neoadjuvant chemotherapy have been investigated in a few studies. Our purpose was to evaluate the oncological outcomes of LG and OG after neoadjuvant chemotherapy in patients with locally advanced gastric cancer (GC) and to determine the advantages, preferences, and ease of use of the two techniques after chemotherapy. Methods We conducted a retrospective chart review of all patients who underwent either OG (n = 43) or LG (n = 41). The neoadjuvant treatment regimen consisted of capecitabine plus oxaliplatin for three cycles, which was then repeated 6 to 12 weeks after the operation for four cycles. Results The hospital stay time and intraoperative blood loss in the LG group were significantly lower than those in the OG group. The mortality rate and the 3-year survival rate for patients in the LG group were comparable to those of patients in the OG group (4.6% vs. 9.7% and 68.3% vs. 58.1%, respectively). Similar trends were observed regarding the 3-year recurrence rate and metastasis. The mean survival time was 52.9 months (95% confidence interval [CI], 44.2–61.6) in the OG group compared with 43.3 (95% CI, 36.6–49.8) in the LG group. Likewise, the mean disease-free survival was 56.1 months (95% CI, 46.36–65.8) in the LG group compared with 50.9 months (95% CI, 44.6–57.2) in the OG group. Conclusion LG is a feasible and safe alternative to OG for patients with locally advanced GC receiving neoadjuvant chemotherapy.

The Impact

BackgroundThe relationship between time to surgery (TTS) and survival benefit is not sufficiently demonstrated by previous studies in locally advanced gastric cancer (LAGC). This study aims to assess the impact of TTS after neoadjuvant chemotherapy (NACT) on long-term and short-term outcomes in LAGC patients.MethodsData were collected from patients with LAGC who underwent NACT between January 2007 and January 2018 at our institution. Outcomes assessed were long-term survival, pathologic complete response (pCR) rate, and postoperative complications.ResultsThis cohort of 426 patients was divided into five groups by weeks of TTS. Under cox regression, compared to other groups, the 22–28 days and 29–35 days groups revealed a better OS (≤21 vs. 22–28 days: HR 1.54, 95% CI = 0.81–2.93, P = 0.185; 36–42 vs. 22–28 days: HR 2.20, 95% CI = 1.28−3.79, P = 0.004; 43–84 vs. 22–28 days: HR 1.83, 95% CI = 1.09–3.06, P = 0.022) and PFS (≤21 vs. 22–28 days: HR 1.54, 95% CI = 0.81–2.93, P = 0.256; 36–42 vs. 22–28 days: HR 2.20, 95% CI = 1.28−3.79, P = 0.111; 43–84 vs. 22–28 days: HR 1.83, 95% CI = 1.09–3.06, P = 0.047). Further analysis revealed a better prognosis in patients with TTS within 22–35 days (OS: HR 1.78 95% CI = 1.25−2.54, P = 0.001; PFS: HR 1.49, 95% CI = 1.07−2.08, P = 0.017). Postoperative stay was significantly higher in the ≤21 days group, while other parameters revealed no statistical significance (P > 0.05). Restricted cubic spline depicted the nonlinear relationship between TTS and OS/PFS.ConclusionPatients who received surgery within 3−5 weeks experienced the maximal survival benefit without an increase in postoperative complications or lowering the rate of pCR. Further investigations are warranted.
