gastric cancer  \nNing Li1,2, Hui Wu1,2, Xin Xu1,2, Qinming Wei1, Yongfeng Ding1, Shan Liu1, Jinqiong Wu1, Yulong Zheng1, Nong Xu1, Yuan Gao1 & Haiping Jiang1*  \nAdjuvant oxaliplatin plus S‑1 (SOX) chemotherapy for gastric cancer (GC) after D2 gastrectomy has been proven effective. There has yet to be a study that evaluates adjuvant nanoparticle albumin‑ bound paclitaxel (nab‑paclitaxel) plus S‑1. In this single‑center, retrospective study, GC patients after D2 gastrectomy received either nab‑paclitaxel plus S‑1 (AS group) or SOX group were recruited between January 2018 and December 2020 in The First Affiliated Hospital of Zhejiang University. Intravenous nab‑paclitaxel 120 mg/m2 or 260 mg/m2 and oxaliplatin 130 mg/m2 were administered as eight 3 week cycle, especially in theAS and SOX group. Patients received S‑1 twice daily with a dose of 40 mg/m2 in the two groups on days 1–14 of each cycle. The end points were disease‑free survival (DFS) rate at 3 years and adverse events (AEs). There were 56 eligible patients, 28 in the AS group and 35 in the SOX group. The 3 year DFS rate was 78.0% in AS group versus 70.7% in SOX group (p = 0.46). Subgroup analysis showed that the patients with signet‑ring positive in the AS group hada prolonged DFS compared with the SOX group (40.0 vs. 13.8 m, p= 0.02). The diffuse‑type GC or low differentiation in the AS group was associated with numerically prolonged DFS compared with the SOX group, but the association was not statistically significant (p = 0.27 and p = 0.15 especially) . Leukopenia (14.3%) were the most prevalent AEs in the AS group, while thrombocytopenia (28.5%) in the SOX group. Neutropenia (7.1% in AS group) and thrombocytopenia (22.8% in SOX group) were the most common grade 3 or 4 AEs. In this study analyzing past data, a tendency towards a greater 3 year DFS was observed when using AS regimen in signet‑ring positive patients. AS group had fewer thrombocytopenia compared to SOX group. More studies should be conducted with larger sample sizes.  \nKeywords Gastric cancer, Adjuvant chemotherapy, Albumin-bound paclitaxel, S-1, Disease free survival  \nWorldwide, there are more than one million fresh instances of gastric cancer (GC), placing it fifth in terms of occurrence and fourth in terms of fatality1. In 2020, it was estimated that there were 769,000 deaths (equivalent to one in every 13 deaths) . There is a two-fold increase in male rates compared to female rates. There is a serious burden of GC in China due to its high incidence. According to the latest data2, GC ranked as the third most prevalent cancer and the third leading cause of cancer-related deaths in China in 2022.  \nSurgery represents the primary treatment option for managing early-stage and locally advanced GC. Recurrence rates following surgery are high, with approximately 40% of patients experiencing relapse within two years after surgery. GC spreads through the lymphatic system, bloodstream, and peritoneum early in the disease process3. Different adjuvant treatments have been investigated for decades to enhance post-surgical relapse control. Several large phase III clinical studies have demonstrated that adjuvant chemotherapy after D2 radical resection can improve survival outcomes in GC patients4–6. The trial showed that S-1 monotherapy as adjuvant chemotherapy provided a survival advantage for stage II-III GC4.
