Introduction. The effectiveness of the Asian regimen of adjuvant chemotherapy in patients with gastric cancer in the European population remains unclear. The aim of our study was a retrospective assessment of adjuvant chemotherapy (XELOX regimen) after radical surgery (R0) on overall survival. Methods. Database of pts with resectable gastric cancer with stage >pT3 and/or pN+ and M0, who were operated (R0) at single oncological institution during 2007-2017 was reviewed. In univariate and multivariate analyzes were included demographic characteristics, type of tumor according to Lauren, stage, type of treatment and others. Results. 396 pts were identified and 286 were available for analysis.106 (37%) pts received at least one cycle of adjuvant chemotherapy. In univariate analysis, 5OS rate was 64% [95% Cl, 52-80] и 56% [95% Cl, 48-64; p=0,21] in patients received adjuvant chemotherapy and only surgical treatment. After stratifying patients depending on the regional lymph nodes metastasis, 5OS rate in pts with pN1-3 was 69% [95% CI, 57-85] vs 47% [95% CI, 39-58; p = 0,01], respectively...

Abstract Background The benefits of adjuvant chemotherapy for elderly patients with gastric cancer (GC) remain unknown because elderly patients are underrepresented in most clinical trials. This study aimed to evaluate the effectiveness and complications of adjuvant chemotherapy in patients > 65 years of age after laparoscopic D2 gastrectomy. Methods This was a single-center retrospective cohort study of elderly patients (> 65 years) with stage II/III GC who underwent curative laparoscopic D2 gastrectomy with R0 resection between 2004 and 2018. The adjuvant chemotherapy regimens included monotherapy (oral capecitabine) and doublet chemotherapy (oral capecitabine plus intravenous oxaliplatin [XELOX] or intravenous oxaliplatin, leucovorin, and 5-fluorouracil [FOLFOX]). The data were retrieved from a prospectively registered database maintained at the Department of General Surgery in Nanfang Hospital, China. The patients were divided as surgery alone and surgery plus adjuvant chemotherapy (chemo group). The overall survival (OS), disease-free survival (DFS), chemotherapy duration, and toxicity were examined. Results There were 270 patients included: 169 and 101 in the surgery and chemo groups, respectively. There were 10 (10/101) and six (6/101) patients with grade 3+ non-hematological and hematological adverse events. The 1−/3−/5-year OS rates of the surgery group were 72.9%/51.8%/48.3%, compared with 90.1%/66.4%/48.6% for the chemo group (log-rank test: P = 0.018). For stage III patients, the 1−/3−/5-year OS rates of the surgery group were 83.7%/40.7%/28.7%, compared with 89.9%/61.2%/43.6% for the chemo group (log-rank test: P = 0.015). Adjuvant chemotherapy was significantly associated with higher OS (HR = 0.568, 95%CI: 0.357–0.903, P = 0.017) and DFS (HR = 0.511, 95%CI: 0.322–0.811, P = 0.004) in stage III patients. Conclusions This study suggested that adjuvant chemotherapy significantly improves OS and DFS compared with surgery alone in elderly patients with stage III GC after D2 laparoscopic gastrectomy, with a tolerable adverse event profile.

Purpose: To evaluate the survival benefit of adjuvant chemotherapy after curative resection in serosa-negative gastric cancer patients (excluding patients who were T1N0), we conducted a multicenter phase III clinical trial in which 13 cancer centers in Japan participated. Patients and Methods: From January 1993 to December 1994, 252 patients were enrolled into the study and allocated randomly to adjuvant chemotherapy or surgery alone. The chemotherapy comprised intravenous mitomycin 1.33 mg/m2, fluorouracil (FU) 166.7 mg/m2, and cytarabine 13.3 mg/m2 twice weekly for the first 3 weeks after surgery, and oral FU 134 mg/m2 daily for the next 18 months for a total dose of 67 g/m2. The primary end point was relapse-free survival. Overall survival and the site of recurrence were secondary end points. Results: Ninety-eight percent of patients underwent gastrectomy with D2 or greater lymph node dissection. There were no treatment-related deaths and few serious adverse events. There was no significant difference in relapse-free and overall survival between the arms (5-year relapse-free survival 88.8% chemotherapy v 83.7% surgery alone; P = .14 and 5-year survival 91.2% chemotherapy v 86.1% surgery alone; P = .13, respectively). Nine patients (7.1%) in the chemotherapy arm and 17 patients (13.8%) in the surgery-alone arm had cancer recurrence. Conclusion: There was no statistically significant relapse-free or overall survival benefit with this adjuvant chemotherapy for patients with macroscopically serosa-negative gastric cancer after curative resection, and there was no statistical difference between the two arms relating to the types of cancer recurrence. We do not recommend adjuvant chemotherapy with this regimen for this population in clinical practice.

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.
