Key clinical point: RHOA expression level is associated with clinical features, including Union for International Cancer Control (UICC) stage progression and poorly differentiated status, in patients with gastric cancer.

Major finding: High/positive RHOA expression was significantly associated with UICC stage progression (III-IV vs I-II: odds ratio [OR] 1.37; P  =  .02) and poorly differentiated status (poorly differentiated vs well/moderately differentiated: OR,1.65; P  =  .02).

Study details: This was a meta-analysis of 10 retrospective case-control studies including 1389 patients with gastric cancer, of which 735 were RHOA positive and 654 were RHOA negative.

Disclosures: This study was sponsored by the Basic Science Research Program, through the National Research Foundation of Korea, funded by the Ministry of Education, and the Gachon University Gil Medical Center. The authors declared no conflicts of interest.

Key clinical point: Both initial radiological clinical stage (cStage) and post-neoadjuvant chemotherapy pathological stage (ypStage) are independent factors associated with survival outcomes in patients treated with neoadjuvant chemotherapy for gastric cancer.

Major finding: cStage IIIC vs II was independently associated with a poor progression-free survival (PFS; adjusted hazard ratio [aHR] 3.53; P  =  .02) and overall survival (OS; aHR 4.55; P  =  .02). ypStage II and III vs 0/I were independent factors for poor PFS (aHR 3.11; P  =  .01 and aHR 6.98; P < .01, respectively) and OS (aHR 3.49; P  =  .02 and aHR 6.89; P < .01, respectively).

Study details: This post hoc analysis of the PRODIGY study included 212 patients with gastric cancer who received neoadjuvant chemotherapy followed by surgical resection and adjuvant S-1.

Disclosures: The PRODIGY study was sponsored by Sanofi. Some authors declared serving as consultants for and receiving honoraria from various sources.

Key clinical point: A low baseline albumin level is significantly associated with hyperprogressive disease (HPD) development and worse survival outcomes after programmed cell death-1 (PD-1) blockade in patients with advanced gastric cancer (AGC).

Major finding: The optimal albumin cut-off value for predicting HPD was <3.25 mg/dL, with an area under the receiver operating curve of 0.7708 (P  =  .0022). Patients with albumin levels of <3.25 mg/dL had worse progression-free (hazard ratio [HR] 1.928; 95% CI 1.289-2.885) and overall (HR 1.833; 95% CI 1.211-2.774) survival.

Study details: This retrospective study included 169 patients with AGC who received PD-1 blockade therapy (nivolumab or pembrolizumab; n = 112) or irinotecan monotherapy (n = 57).

Key clinical point: Despite lower complete resection rates and a higher risk for recurrence, endoscopic resection (ER) offers similar long-term survival outcomes and serious adverse event (AE) rates and shorter hospital stays compared with surgery in early gastric cancer (EGC).

Major finding: The ER vs surgery group had a lower complete resection rate (risk difference [RD] −0.1; P < .00001), shorter length of hospital stay (P < .00001), higher rate of recurrence (RD 0.07; P < .00001), and comparable 5-year overall survival (RD −0.01; P  =  .38), cancer-specific survival (RD 0.01; P < .17), and serious AE rate (RD −0.03; P  =  .13).

Study details: This was a meta-analysis of 29 observational cohort studies (prospective: n = 2; retrospective: n = 27) involving 20,559 patients with EGC who underwent ER (n = 7709) or surgery (n = 12,850).

Key clinical point: Endoscopic resection (ER) achieves favorable long-term survival outcomes in patients with early gastric cancer (EGC) in the real-world setting.

Major finding: The overall 5-year overall survival (OS) rate was 89.0% (95% CI 88.3%-89.6%). The lower limit of the 95% CI for the 5-year OS rate exceeded the threshold 5-year OS rate in all categories of pathological curability, including curative resection for expanded indications.

Study details: The data come from a multicenter prospective cohort study, J-WEB/EGC, that included 9054 patients with 10,021 EGC lesions who underwent ER.

Disclosures: This study was supported by the Japanese Ministry of Health, Labour, and Welfare, and Daiwa Securities Health Foundation. The authors declared no conflicts of interest.
