Background. The prognosis of patients with advanced gastric cancer remains unsatisfactory, highlighting the need for improved therapeutic strategies. We analyzed 23 resectable advanced gastric cancer patients who received FLOT followed by laparoscopic gastrectomy with D2 lymphadenectomy to evaluate the efficacy and safety. Methods. Patients aged 18–75 years with gastric adenocarcinoma (stage cT3–4 and/or N + M0) underwent neoadjuvant FLOT therapy (four preoperative and four postoperative 2-week cycles) at Shanghai East Hospital. Laparoscopic gastrectomy was scheduled 3-4 weeks after completion of the last cycle of preoperative chemotherapy. The type of surgical procedure was determined by the location and extent of the primary tumor. Results. 23 patients were reviewed in the study. 20 patients (81.2%) received four courses of FOLT therapy, while 3 patients (18.8%) received three courses of treatment. There were 3 (13.0%) complete responses, 13 (56.5%) partial responses, 4 (26.1%) of stable disease, and 1 (4.3%) of progressive disease. The clinical efficacy response rate was 69.6%. The R0 resection rate was 91.3%. Only one patient exhibited grade III postoperative complications. The pathologic complete remission was 13%. The common grade 3/4 adverse events from chemotherapy were leucopenia (17.4%), neutropenia (30.4%), anemia (13%), anorexia (13%), and nausea (17.4%). Postoperative complications occurred in 5 patients (26.1%). There was no treatment-related mortality or reoperation. The most reason for not completing chemotherapy was the patient’s request. Conclusions. These findings suggest that FLOT neoadjuvant chemotherapy, followed by laparoscopic D2 gastrectomy, is effective and safe in advanced, resectable advanced gastric cancer.

Abstract Background: Limited researches focused on the application of laparoscopic gastrectomy (LG) in locally advanced gastric cancer (LAGC) patients following neoadjuvant chemotherapy (NACT). In this study, we aimed at illustrating the surgical and survival outcome of LG in LAGC patients following NACT.Methods: We performed a retrospective study of patients with LAGC who received either LG following NACT or upfront LG at Fujian Provincial Hospital between March 2013 and October 2018. Perioperative parameters, short-term and long-term outcomes were compared. The Kaplan-Meier estimator was used to describe the survival curves, and the differences were examined by the log-rank test.Results: In total, 76 consecutive patients were enrolled into the NACT-LG (41 patients) and LG (35 patients) group, respectively. There was no significant difference between the two groups for baseline characteristics, including age, sex, BMI, Eastern Clinical Oncology Group performance status, tumor size, location, Borrmann type, Lauren type, differentiation, cT stage, and surgical type (all P>0.05). The surgical trauma in terms of incision length and blood loss, and postoperative recovery in terms of first aerofluxus time, first time on liquid diets, drainage duration, and hospital stays were similar between the two groups (all P>0.05). The operation time was significantly longer for NACT-LG than for LG (286.5 vs. 248.9 min, P=0.008). There was no significant difference in surgical morbidity (19.5% vs. 22.9%, P=0.721) between the two groups. No patient died of postoperative complications in the NACT-LG group, and one patient (1/35, 2.9%) died of postoperative complications in the LG group (P=0.461). After NACT, the R0 resection rate was significantly higher (95.1% vs. 77.1%, P=0.049), and metastatic lymph nodes were less for NACT-LG than for LG (1 vs. 8, P=0.001). Compared with the LG group, the NACT-LG group had a significantly better DFS (59.4% vs. 14.4%, P=0.034) and better OS (69.0% vs. 37.4%, P=0.009) at 3 years.Conclusions: NACT does not decrease safety of LG for patients with LAGC and offer higher R0 resection rate and better disease-free and overall survival. For patients with LAGC, LG following NACT should be the priority treatment.

96 Background: The aim of this study was to evaluate feasibility and safety of neoadjuvant docetaxel, oxaliplatin, and S-1 (DOS) chemotherapy in patients with potentially resectable adenocarcinoma of stomach or gastroesophageal junction. Methods: Forty-one patients with clinical stage T3-4N0M0 or T2-4N+M0 determined by CT, endoscopic ultrasonography, and laparoscopy were enrolled between DEC 2008 and MAR 2010. Gastrectomy with D2 lymph node dissection was conducted after 3 cycles of DOS chemotherapy. DOS chemotherapy consists of docetaxel 50 mg/m2 iv (day1), oxaliplatin 100 mg/m2 iv (day1), and S-1 40 mg/m2 po bid (days1-14) at 3 weeks interval. After curative gastrectomy, the patients were given 1 year of adjuvant chemotherapy with S-1 (40 mg/m2 D1-28, every 6 weeks). Results: All patients finished the planned neoadjuvant chemotherapy. Twenty-three (56%) patients achieved a partial response, and the remaining 18 patients had stable disease by CT scan after 3 cycles of DOS chemotherapy. No disease progression was observed during the neoadjuvant chemotherapy. A median 4.7 weeks (range, 4.0-7.6) after the start of the 3rd cycle of DOS chemotherapy, 39 (95%) patients underwent R0 resection with no pathologic residual disease in 4 (10%) patients. Hematologic toxicities were common including grade 4 neutropenia (32%), grade 3 thrombocytopenia (17%), and febrile neutropenia (10%). However, hematologic toxicities were generally transient and manageable. There were no grade 3 or 4 non-hematologic toxicities with frequency > 5% of patients. With all toxicities taken together, 21 (51%) patients experienced grade 3 or 4 toxicities (except grade 3 neutropenia). There was no treatment-related death, and surgical complications included only mild wound problem in 4 (10%) patients. Conclusions: In this study, neoadjuvant DOS chemotherapy could induce a sufficient down-staging and R0 resection of locally advanced gastric cancer with mild and manageable toxicities. A phase III randomized trial is planned for evaluating the benefit of neoadjuvant DOS chemotherapy in patients with locally advanced gastric cancer. [Table: see text]

BACKGROUND The oncological efficacy and safety of laparoscopic gastrectomy are under debate for the Western population with predominantly advanced gastric cancer undergoing multimodality treatment. METHODS In 10 experienced upper GI centers in the Netherlands, patients with resectable (cT1-4aN0-3bM0) gastric adenocarcinoma were randomly assigned to either laparoscopic or open gastrectomy. No masking was performed. The primary outcome was hospital stay. Analyses were performed by intention to treat. It was hypothesized that laparoscopic gastrectomy leads to shorter hospital stay, less postoperative complications, and equal oncological outcomes. RESULTS Between 2015 and 2018, a total of 227 patients were randomly assigned to laparoscopic (n = 115) or open gastrectomy (n = 112). Preoperative chemotherapy was administered to 77 patients (67%) in the laparoscopic group and 87 patients (78%) in the open group. Median hospital stay was 7 days (interquartile range, 5-9) in both groups ( P = .34). Median blood loss was less in the laparoscopic group (150 v 300 mL, P < .001), whereas mean operating time was longer (216 v 182 minutes, P < .001). Both groups did not differ regarding postoperative complications (44% v 42%, P = .91), in-hospital mortality (4% v 7%, P = .40), 30-day readmission rate (9.6% v 9.1%, P = 1.00), R0 resection rate (95% v 95%, P = 1.00), median lymph node yield (29 v 29 nodes, P = .49), 1-year overall survival (76% v 78%, P = .74), and global health-related quality of life up to 1 year postoperatively (mean differences between + 1.5 and + 3.6 on a 1-100 scale; 95% CIs include zero). CONCLUSION Laparoscopic gastrectomy did not lead to a shorter hospital stay in this Western multicenter randomized trial of patients with predominantly advanced gastric cancer. Postoperative complications and oncological efficacy did not differ between laparoscopic gastrectomy and open gastrectomy.

205 Background:TAS-118 (S-1 and leucovorin) + oxaliplatin (L-OHP) improved overall survival (OS) compared to S-1 + cisplatin for patients (pts) with advanced gastric cancer (GC) (Kang, Lancet Oncol. 2020). This study investigated the feasibility of peri (pre and post)-operative (op) chemotherapy (chemo) with TAS-118 ± L-OHP in pts with locally advanced resectable GC. While it was reported that pre-op TAS-118 + L-OHP followed by D2 gastrectomy was well tolerated and showed promising efficay (Takahari, ASCO-GI. 2020), the recommended post-op chemo regimen, TAS-118 or TAS-118 + L-OHP, has yet to be determined. Methods:Eligible pts with GC of clinical T3-4N1-3M0 were enrolled. The protocol treatment consisted of pre-op chemo with 4 courses of TAS-118 (40-60 mg/body, orally, twice daily, 7 days) + L-OHP (85 mg/m2, intravenously, day 1) in a 2-week cycle, and gastrectomy with D2 lymphadenectomy, followed by post-op chemo with 12 courses of TAS-118 (step 1) and 8 courses of TAS-118 + L-OHP (step 2). Step 2 was started if the dose-limiting toxicity (DLT) occurred in < 6 of 10 pts in step 1. Up to 20 pts were included in the analysis of feasibility after a recommended regimen was determined. Results:Between December 2016 and February 2019, 45 pts were enrolled. The numbers of pts with cT3/4a and cN1/2/3 were 13/32 and 25/17/3, respectively. Excluding 14 pts (4 achieving pathological complete response, 4 not satisfying the criteria for post-op chemo, 3 physician judgement or pt withdrawal, 2 progressive disease, 1 adverse event [AE]), 31 pts (11/20 in step 1/2) received the post-op chemo. No DLT was observed in either step. The post-op chemo completion rate was 90.9% (95% CI, 63.6-99.5) in step 1 and 80.0% (95% CI, 59.9-92.9) in step 2. The median relative dose intensity of TAS-118 in step 1 was 83.3%, and those of TAS-118 and L-OHP in step 2 were 69.9% and 74.3%, respectively. One pt in step 2 discontinued post-op chemo due to AE. Grade ³ 3 AEs observed in ≥ 10% of pts were weight loss in both step 1 and step 2 (2 in each), and hypokalemia (n = 3) and neutropenia (n = 2) in step 2. At 1-year follow-up after the last pt was enrolled, recurrence-free survival and OS rates were 91.1% (95% CI, 78.0-96.6) and 100%, respectively at 12 months, and 69.1% (95% CI, 49.6-82.3) and 95.5% (95% CI, 71.9-99.3), respectively at 24 months. Conclusions:Taken together with the feasibility and efficacy of pre-op chemo, peri-op chemo with TAS-118 + L-OHP with D2 gastrectomy was well tolerated and showed promising efficacy.

Objective: The aim of this study was to compare the clinical efficacy of neoadjuvant chemoradiotherapy (NACRT) combined with postoperative adjuvant XELOX (Oxaliplatin +Capecitabine) chemotherapy and postoperative adjuvant chemotherapy (ACT) with XELOX for local advanced gastric cancer (LAGC). Methods: In this prospectively randomized trial, we investigated the effect of NACRT combined with postoperative ACT for LAGC. 60 patients were randomly divided into NACRT group and ACT group, with 30 patients in each group. Patients in NACRT group were given three-dimensional conformal radiotherapy (45 Gy/1.8 Gy/f) accompanied by synchronous XELOX of two cycles, followed by surgery, and then postoperative adjuvant XELOX chemotherapy of four cycles was performed. Patients in ACT group received surgery in advance, and then XELOX chemotherapy of six cycles was given. Results: The objective response rate of NACRT was 76.7%. The overall incidence of postoperative complications in NACRT group was not significantly different from that in ACT group (23.1% vs 30.0%, p = 0.560). The 1 year, 2 years, and 3 years progression-free survival (PFS）and overall survival (OS) in NACRT and ACT groups were 80.0% vs 56.7%, 73.3% vs 46.7%, 60.0% vs 33.3%, and 86.7% vs 80.0%, 76.7% vs 66.7%, 63.3% vs 50.0%, respectively. Patients in NACRT group showed a significantly higher R0 resection rate (84.6% vs 56.7%, p = 0.029),lower loco-regional recurrence rate (36.7% vs 11.5%, p = 0.039), longer PFS (p = 0.019) and freedom from locoregional progression(FFLP) (p = 0.004) than patients in ACT group, while there was no difference in OS (p = 0.215) and in toxicity incidence (p > 0.05). Conclusions: NACRT combined with postoperative adjuvant XELOX chemotherapy can improve R0 resection rate, reduce loco-regional recurrence, prolong PFS and FFLP without increasing the incidence of postoperative complications in patients with LAGC. Advances in knowledge: Compared with postoperative adjuvant chemotherapy, locally advanced gastric cancer patients may benefit from neoadjuvant chemoradiotherapy, and toxicity associated with chemoradiotherapy was tolerant and manageable.
