Abstract
PURPOSE This first-in-human phase I dose-escalation study evaluated the safety, pharmacokinetics, and efficacy of tinengotinib (TT-00420), a multi-kinase inhibitor targeting fibroblast growth factor receptors 1-3 (FGFRs 1-3), Janus kinase 1/2, vascular endothelial growth factor receptors, and Aurora A/B, in patients with advanced solid tumors. PATIENTS AND METHODS Patients received tinengotinib orally daily in 28-day cycles. Dose escalation was guided by Bayesian modeling using escalation with overdose control. The primary objective was to assess dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), and dose recommended for dose expansion (DRDE). Secondary objectives included pharmacokinetics and efficacy. RESULTS Forty-eight patients were enrolled (dose escalation, n = 40; dose expansion, n = 8). MTD was not reached; DRDE was 12 mg daily. DLTs were palmar-plantar erythrodysesthesia syndrome (8 mg, n = 1) and hypertension (15 mg, n = 2). The most common treatment-related adverse event was hypertension (50.0%). In 43 response-evaluable patients, 13 (30.2%) achieved partial response (PR; n = 7) or stable disease (SD) ≥ 24 weeks (n = 6), including 4/11 (36.4%) with FGFR2 mutations/fusions and cholangiocarcinoma (PR n = 3; SD ≥ 24 weeks n = 1), 3/3 (100.0%) with hormone receptor (HR)-positive/HER2-negative breast cancer (PR n = 2; SD ≥ 24 weeks n = 1), 2/5 (40.0%) with triple-negative breast cancer (TNBC; PR n = 1; SD ≥ 24 weeks n = 1), and 1/1 (100.0%) with castrate-resistant prostate cancer (CRPC; PR). Four of 12 patients (33.3%; HR-positive/HER2-negative breast cancer, TNBC, prostate cancer, and cholangiocarcinoma) treated at DRDE had PRs. Tinengotinib's half-life was 28-34 hours. CONCLUSIONS Tinengotinib was well tolerated with favorable pharmacokinetic characteristics. Preliminary findings indicated potential clinical benefit in FGFR inhibitor-refractory cholangiocarcinoma, HER2-negative breast cancer (including TNBC), and CRPC. Continued evaluation of tinengotinib is warranted in phase II trials.

Abstract
Diffuse-type gastric adenocarcinoma (DGAC) is a deadly cancer often diagnosed late and resistant to treatment. While hereditary DGAC is linked to CDH1 mutations, the role of CDH1/E-cadherin inactivation in sporadic DGAC tumorigenesis remains elusive. We discovered CDH1 inactivation in a subset of DGAC patient tumors. Analyzing single-cell transcriptomes in malignant ascites, we identified two DGAC subtypes: DGAC1 (CDH1 loss) and DGAC2 (lacking immune response). DGAC1 displayed distinct molecular signatures, activated DGAC-related pathways, and an abundance of exhausted T cells in ascites. Genetically engineered murine gastric organoids showed that Cdh1 knock-out (KO), KrasG12D, Trp53 KO (EKP) accelerates tumorigenesis with immune evasion compared with KrasG12D, Trp53 KO (KP). We also identified EZH2 as a key mediator promoting CDH1 loss-associated DGAC tumorigenesis. These findings highlight DGAC's molecular diversity and potential for personalized treatment in CDH1-inactivated patients.

Abstract
Efforts to improve the prognosis for patients with locally advanced esophageal or gastroesophageal junction (GEJ) adenocarcinoma have focused on neoadjuvant approaches to increase the pathological complete response (pathCR) rate, improve surgical resection, and prolong event-free and overall survival (OS). Building on the recent evidence that PD-1 inhibition plus chemotherapy improves the OS of patients with metastatic GEJ adenocarcinoma, we evaluated whether the application of this strategy in the neoadjuvant setting would improve the pathological response. This single-center phase I/II trial evaluated the safety, toxicity, and efficacy of neoadjuvant atezolizumab with oxaliplatin and 5-fluorouracil (modified FOLFOX) followed by esophagectomy followed by atezolizumab. The primary objective goal was to achieve 20% pathCR. From the twenty enrolled patients, eighteen underwent resection and two (10%, 95% CI: 1.24-31.7%) achieved pathCR. After a median follow-up duration of 40.7 months, 11 patients had disease recurrence and 10 had died. The median disease-free and OS were 28.8 (95% CI: 14.7, NA) and 38.6 months (95% CI: 30.5, NA), respectively. No treatment-related adverse events led to death. Although modified FOLFOX plus atezolizumab did not achieve the expected pathCR, an acceptable safety profile was observed. Our results support the continued development of a more refined strategy (neoadjuvant chemotherapy plus perioperative immunotherapy/targeted agents) with molecular/immune profiling in parallel.

Abstract
BACKGROUND The clinical impact of SMARCA4 mutations (SMARCA4ms) in gastroesophageal adenocarcinoma (GEA) remains underexplored. This study aimed to examine the association of SMARCA4ms with clinical outcomes and co-occurrence with other gene mutations identified through a next-generation sequencing (NGS) panel in GEA patients. METHODS A total of 256 patients with metastatic or recurrent GEA who underwent NGS panel profiling at the MD Anderson Cancer Center between 2016 and 2022 were included. Comparative analyses were performed to assess clinical outcomes related to SMARCA4ms. The frequency and types of SMARCA4ms and their co-occurrence with other gene mutations were also examined. RESULTS SMARCA4ms were identified in 19 patients (7.4%). These SMARCA4ms were significantly associated with non-signet ring cell subtype (p = 0.044) and PD-L1 positive expression (p = 0.046). No difference in survival between the SMARCA4m and SMARCA4-normal group was observed (p = 0.84). There were significant associations between SMARCA4ms and FANCA, IGF1R, KRAS, FANCL, and PTEN alterations. Notably, 15 of the 19 SMARCA4m cases involved SNV missense mutations, with frequent co-occurrences noted with TP53, KRAS, ARID1A, and ERBB2 mutations. CONCLUSIONS These results serve as the first comprehensive examination of the relationship between SMARCA4ms and clinical outcomes in GEA.

Abstract
Esophageal, gastroesophageal junction, and gastric adenocarcinomas, referred to collectively as gastroesophageal adenocarcinomas (GEAs), are a major cause of global cancer-related mortality. Our increasing molecular understanding has led to the addition of biomarker-directed approaches to defined subgroups and has improved survival in selected patients, such as those with HER2 and Claudin18.2 overexpression. Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of cancer, including GEA, but biomarkers beyond PD-L1 expression are lacking. Mismatch repair deficiency and/or high microsatellite instability (dMMR/MSI-H) is observed in 8% to 22% of nonmetastatic GEA, and 3% to 5% of patients with metastatic disease. dMMR/MSI-H tumors are associated with more favorable prognosis and significant benefit from ICIs, although some heterogeneity exists. The activity of ICIs in advanced dMMR/MSI-H cancer is seen across lines of therapy and should be recommended in the frontline setting. In patients with nonmetastatic dMMR/MSI-H cancer, increasing evidence suggests that perioperative and adjuvant chemotherapy may not provide benefit to the dMMR/MSI-H subgroup. The activity of perioperative chemotherapy-free immune checkpoint regimens in patients with nonmetastatic dMMR/MSI-H cancer is highly promising and underscores the need to identify this unique subgroup. We recommend MMR/MSI testing for all patients with GEA at diagnosis, and review the key rationale and clinical management implications for patient with dMMR/MSI-H tumors across disease stages.

Abstract
Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We report 3-year efficacy and safety results from the phase III CheckMate 649 trial. Patients with previously untreated advanced or metastatic gastroesophageal adenocarcinoma were randomly assigned to nivolumab plus chemotherapy or chemotherapy. Primary end points were overall survival (OS) and progression-free survival (PFS) by blinded independent central review (BICR) in patients whose tumors expressed PD-L1 combined positive score (CPS) ≥5. With 36.2-month minimum follow-up, for patients with PD-L1 CPS ≥5, the OS hazard ratio (HR) for nivolumab plus chemotherapy versus chemotherapy was 0.70 (95% CI, 0.61 to 0.81); 21% versus 10% of patients were alive at 36 months, respectively; the PFS HR was 0.70 (95% CI, 0.60 to 0.81); 36-month PFS rates were 13% versus 8%, respectively. The objective response rate (ORR) per BICR was 60% (95% CI, 55 to 65) with nivolumab plus chemotherapy versus 45% (95% CI, 40 to 50) with chemotherapy; median duration of response was 9.6 months (95% CI, 8.2 to 12.4) versus 7.0 months (95% CI, 5.6 to 7.9), respectively. Nivolumab plus chemotherapy also continued to show improvement in OS, PFS, and ORR versus chemotherapy in the overall population. Adding nivolumab to chemotherapy maintained clinically meaningful long-term survival benefit versus chemotherapy alone, with an acceptable safety profile, supporting the continued use of nivolumab plus chemotherapy as standard first-line treatment for advanced gastroesophageal adenocarcinoma.

Abstract
Zanidatamab is a bispecific HER2-targeted antibody which has demonstrated antitumor activity in a broad range of HER2 amplified/expressing solid tumors. We determined the antitumor activity of zanidatamab in patient-derived xenograft (PDX) models developed from pre-treatment or post-progression biopsies on the first-in-human zanidatamab phase I study (NCT02892123). Of 36 tumors implanted, 19 PDX models were established (52.7% take rate) from 17 patients. Established PDXs represented a broad range of HER2-expressing cancers, and in vivo testing demonstrated an association between antitumor activity in PDXs and matched patients in 7 of 8 co-clinical models tested. We also identified amplification of MET as a potential mechanism of acquired resistance to zanidatamab and demonstrated that MET inhibitors have single agent activity and can enhance zanidatamab activity in vitro and in vivo. These findings provide evidence that PDXs can be developed from pre-treatment biopsies in clinical trials and may provide insight into mechanisms of resistance.

Abstract
BACKGROUND Whereas current guidelines recommend staging laparoscopy for most patients with potentially resectable gastric cancer, such a recommendation for patients with adenocarcinoma of the gastroesophageal junction (AEG) is lacking. This study sought to identify baseline clinicopathologic characteristics associated with peritoneal metastasis (PM) among patients with Siewert II AEG. METHODS Trimodality therapy-eligible patients with Siewert II AEG (2000-2015, single institution) were retrospectively identified. A composite PM outcome was defined as follows: (1) PM at staging laparoscopy; (2) PM diagnosed during neoadjuvant chemoradiation; or (3) PM ≤6 months postoperatively. Logistic regression was used to identify features associated with PM; bootstrapped analysis (Youden J) identified the distal tumor extension that best discriminated the composite outcome. RESULTS Of 188 patients, a composite PM outcome was observed in 26 of 188 (13.8%); 12 of 26 had positive staging laparoscopy, 10 of 26 experienced PM during chemoradiation, and 4 of 26 had PM ≤6 months postoperatively. Tumor extension below the GEJ was greater in patients with PM (median, 4.0 cm [interquartile range, 3.0-5.0] vs 3.0 cm [interquartile range, 2.0-3.0]; P < .001). All patients with PM had cT3 to cT4 tumors. Among patients with cT3 to cT4 tumors (n = 168 of 188; 89.4%), distal tumor extent (odds ratio, 1.67/cm; 95% CI, 1.23-2.28; P = .001) was independently associated with increased odds of PM. Gastric tumor extension ≥4 cm remained independently associated with PM (OR, 5.14; 95% CI, 2.11-12.53; P < .001) after adjustment for signet ring cell status. CONCLUSIONS Distal tumor extent beyond the GEJ is independently associated with increased odds of PM in patients with Siewert II AEG. Patients with extensive gastric involvement should therefore be considered for staging laparoscopy before trimodality therapy.

Abstract
Malignant ascites accompanied by peritoneal dissemination contain various factors and cell populations as well as cancer cells; however, how the tumor microenvironment is shaped in ascites remains unclear. Single-cell proteomic profiling and a comprehensive proteomic analysis are conducted to comprehensively characterize malignant ascites. Here, we find defects in immune effectors along with immunosuppressive cell accumulation in ascites of patients with gastric cancer (GC) and identify five distinct subpopulations of CD45(-)/EpCAM(-) cells. Mesothelial cells with mesenchymal features in CD45(-)/EpCAM(-) cells are the predominant source of chemokines involved in immunosuppressive myeloid cell (IMC) recruitment. Moreover, mesothelial-mesenchymal transition (MMT)-induced mesothelial cells strongly express extracellular matrix (ECM)-related genes, including tenascin-C (TNC), enhancing metastatic colonization. These findings highlight the definite roles of the mesenchymal cell population in the development of a protumorigenic microenvironment to promote peritoneal dissemination.

Abstract
PURPOSE In CheckMate 649, first-line nivolumab plus chemotherapy prolonged overall survival versus chemotherapy in patients with advanced/metastatic non-human epidermal growth factor receptor 2 (HER2)-positive gastric/gastroesophageal junction cancer (GC/GEJC) or esophageal adenocarcinoma (EAC). We present exploratory patient-reported outcomes (PROs). METHODS In patients (N = 1,581) concurrently randomly assigned 1:1 to nivolumab plus chemotherapy or chemotherapy and in those with tumor PD-L1 expression at a combined positive score (CPS) of ≥5, health-related quality of life (HRQoL) was assessed using the EQ-5D and Functional Assessment of Cancer Therapy-Gastric (FACT-Ga), which included the FACT-General (FACT-G) and Gastric Cancer subscale (GaCS). The FACT-G GP5 item assessed treatment-related symptom burden. Longitudinal changes in HRQoL were assessed using mixed models for repeated measures in the PRO analysis population (randomly assigned patients with baseline and ≥1 postbaseline assessments). Time to symptom or definitive deterioration analyses were also conducted. RESULTS In the PRO analysis population (n = 1,360), PRO questionnaire completion rates were mostly >80% during treatment. Patient-reported symptom burden was not increased with nivolumab plus chemotherapy versus chemotherapy. Mean improved changes from baseline were greater with nivolumab plus chemotherapy versus chemotherapy for FACT-Ga total, GaCS, and EQ-5D visual analog scale in patients with a CPS of ≥5; results were similar for the overall PRO analysis population. In CPS ≥5 and all randomly assigned populations, nivolumab plus chemotherapy reduced the risk of symptom deterioration versus chemotherapy, on the basis of FACT-Ga total score and GaCS; time to definitive deterioration was longer, and the risk of definitive deterioration in HRQoL was reduced with nivolumab plus chemotherapy across EQ-5D and most FACT-Ga measures (hazard ratio [95% CI] <1). CONCLUSION Compared with chemotherapy alone, first-line nivolumab plus chemotherapy showed stable or better on-treatment HRQoL in patients with advanced/metastatic non-HER2-positive GC/GEJC/EAC and also showed decreased risk of definitive HRQoL deterioration.

Abstract
The peritoneal cavity is a common site of gastric adenocarcinoma (GAC) metastasis. Peritoneal carcinomatosis (PC) is resistant to current therapies and confers poor prognosis, highlighting the need to identify new therapeutic targets. CD47 conveys a "don't eat me" signal to myeloid cells upon binding its receptor signal regulatory protein alpha (SIRPα), which helps tumor cells circumvent macrophage phagocytosis and evade innate immune responses. Previous studies demonstrated that the blockade of CD47 alone results in limited clinical benefits, suggesting that other target(s) might need to be inhibited simultaneously with CD47 to elicit a strong antitumor response. Here, we found that CD47 was highly expressed on malignant PC cells, and elevated CD47 was associated with poor prognosis. Galectin-3 (Gal3) expression correlated with CD47 expression, and coexpression of Gal3 and CD47 was significantly associated with diffuse type, poor differentiation, and tumor relapse. Depletion of Gal3 reduced expression of CD47 through inhibition of c-Myc binding to the CD47 promoter. Furthermore, injection of Gal3-deficient tumor cells into either wild-type and Lgals3-/- mice led to a reduction in M2 macrophages and increased T-cell responses compared with Gal3 wild-type tumor cells, indicating that tumor cell-derived Gal3 plays a more important role in GAC progression and phagocytosis than host-derived Gal3. Dual blockade of Gal3 and CD47 collaboratively suppressed tumor growth, increased phagocytosis, repolarized macrophages, and boosted T-cell immune responses. These data uncovered that Gal3 functions together with CD47 to suppress phagocytosis and orchestrate immunosuppression in GAC with PC, which supports exploring a novel combination therapy targeting Gal3 and CD47. SIGNIFICANCE Dual inhibition of CD47 and Gal3 enhances tumor cell phagocytosis and reprograms macrophages to overcome the immunosuppressive microenvironment and suppress tumor growth in peritoneal metastasis of gastric adenocarcinoma.

Abstract
PURPOSE Cyclin E (CCNE1) has been proposed as a biomarker of sensitivity to adavosertib, a Wee1 kinase inhibitor, and a mechanism of resistance to HER2-targeted therapy. EXPERIMENTAL DESIGN Copy number and genomic sequencing data from The Cancer Genome Atlas and MD Anderson Cancer Center databases were analyzed to assess ERBB2 and CCNE1 expression. Molecular characteristics of tumors and patient-derived xenografts (PDX) were assessed by next-generation sequencing, whole-exome sequencing, fluorescent in situ hybridization, and IHC. In vitro, CCNE1 was overexpressed or knocked down in HER2+ cell lines to evaluate drug combination efficacy. In vivo, NSG mice bearing PDXs were subjected to combinatorial therapy with various treatment regimens, followed by tumor growth assessment. Pharmacodynamic markers in PDXs were characterized by IHC and reverse-phase protein array. RESULTS Among several ERBB2-amplified cancers, CCNE1 co-amplification was identified (gastric 37%, endometroid 43%, and ovarian serous adenocarcinoma 41%). We hypothesized that adavosertib may enhance activity of HER2 antibody-drug conjugate trastuzumab deruxtecan (T-DXd). In vitro, sensitivity to T-DXd was decreased by cyclin E overexpression and increased by knockdown, and adavosertib was synergistic with topoisomerase I inhibitor DXd. In vivo, the T-DXd + adavosertib combination significantly increased γH2AX and antitumor activity in HER2 low, cyclin E amplified gastroesophageal cancer PDX models and prolonged event-free survival (EFS) in a HER2-overexpressing gastroesophageal cancer model. T-DXd + adavosertib treatment also increased EFS in other HER2-expressing tumor types, including a T-DXd-treated colon cancer model. CONCLUSIONS We provide rationale for combining T-DXd with adavosertib in HER2-expressing cancers, especially with co-occuring CCNE1 amplifications. See related commentary by Rolfo et al., p. 4317.

Abstract
In gastroesophageal junction (GEJ) adenocarcinoma cases, a prognosis based on ypTNM staging could be affected by preoperative therapy. Patients with esophageal adenocarcinoma and gastric adenocarcinoma who underwent preoperative therapy followed by surgical resection from 2006 through 2017 were identified in the National Cancer Database. To enable stage-by-stage OS comparisons, tumors were classified into four gross ypTNM groups: ypT1/2, N-negative; ypT1/2, N-positive; ypT3/4, N-negative; and ypT3/4, N-positive. Prognostic factors were examined, and an OS prediction nomogram was developed for patients with abdominal/lower esophageal and gastric cardia adenocarcinoma, representing GEJ cancers. We examined 25,463 patient records. When compared by gross ypTNM group, the abdominal/lower esophageal and gastric cardia adenocarcinoma groups had similar OS rates, differing from those of other esophageal or gastric cancers. Cox regression analysis of patients with GEJ cancers showed that preoperative chemoradiotherapy was associated with shorter OS than preoperative chemotherapy after adjustment for the ypTNM group (hazard ratio 1.31, 95% CI 1.24-1.39, p < 0.001), likely owing to downstaging effects. The nomogram had a concordance index of 0.833 and a time-dependent area under the curve of 0.669. OS prediction in GEJ adenocarcinoma cases should include preoperative therapy regimens. Our OS prediction nomogram provided reasonable OS prediction for patients with GEJ adenocarcinoma, and future validation is needed.

Abstract
Diffuse-type gastric adenocarcinoma (DGAC) is a deadly cancer often diagnosed late and resistant to treatment. While hereditary DGAC is linked to CDH1 gene mutations, causing E-Cadherin loss, its role in sporadic DGAC is unclear. We discovered CDH1 inactivation in a subset of DGAC patient tumors. Analyzing single-cell transcriptomes in malignant ascites, we identified two DGAC subtypes: DGAC1 (CDH1 loss) and DGAC2 (lacking immune response). DGAC1 displayed distinct molecular signatures, activated DGAC-related pathways, and an abundance of exhausted T cells in ascites. Genetically engineered murine gastric organoids showed that Cdh1 knock-out (KO), KrasG12D, Trp53 KO (EKP) accelerates tumorigenesis with immune evasion compared to KrasG12D, Trp53 KO (KP). We also identified EZH2 as a key mediator promoting CDH1 loss-associated DGAC tumorigenesis. These findings highlight DGAC's molecular diversity and potential for personalized treatment in CDH1-inactivated patients.

Abstract
Gastric adenocarcinoma (GAC) is a lethal disease characterized by genomic and clinical heterogeneity. By integrating 8 previously established genomic signatures for GAC subtypes, we identified 6 clinically and molecularly distinct genomic consensus subtypes (CGSs). CGS1 have the poorest prognosis, very high stem cell characteristics, and high IGF1 expression, but low genomic alterations. CGS2 is enriched with canonical epithelial gene expression. CGS3 and CGS4 have high copy number alterations and low immune reactivity. However, CGS3 and CGS4 differ in that CGS3 has high HER2 activation, while CGS4 has high SALL4 and KRAS activation. CGS5 has the high mutation burden and moderately high immune reactivity that are characteristic of microsatellite instable tumors. Most CGS6 tumors are positive for Epstein Barr virus and show extremely high levels of methylation and high immune reactivity. In a systematic analysis of genomic and proteomic data, we estimated the potential response rate of each consensus subtype to standard and experimental treatments such as radiation therapy, targeted therapy, and immunotherapy. Interestingly, CGS3 was significantly associated with a benefit from chemoradiation therapy owing to its high basal level of ferroptosis. In addition, we also identified potential therapeutic targets for each consensus subtype. Thus, the consensus subtypes produced a robust classification and provide for additional characterizations for subtype-based customized interventions.

Abstract
OBJECTIVE Gastric cancer (GC) is a leading cause of cancer mortality, with ARID1A being the second most frequently mutated driver gene in GC. We sought to decipher ARID1A-specific GC regulatory networks and examine therapeutic vulnerabilities arising from ARID1A loss. DESIGN Genomic profiling of GC patients including a Singapore cohort (>200 patients) was performed to derive mutational signatures of ARID1A inactivation across molecular subtypes. Single-cell transcriptomic profiles of ARID1A-mutated GCs were analysed to examine tumour microenvironmental changes arising from ARID1A loss. Genome-wide ARID1A binding and chromatin profiles (H3K27ac, H3K4me3, H3K4me1, ATAC-seq) were generated to identify gastric-specific epigenetic landscapes regulated by ARID1A. Distinct cancer hallmarks of ARID1A-mutated GCs were converged at the genomic, single-cell and epigenomic level, and targeted by pharmacological inhibition. RESULTS We observed prevalent ARID1A inactivation across GC molecular subtypes, with distinct mutational signatures and linked to a NFKB-driven proinflammatory tumour microenvironment. ARID1A-depletion caused loss of H3K27ac activation signals at ARID1A-occupied distal enhancers, but unexpectedly gain of H3K27ac at ARID1A-occupied promoters in genes such as NFKB1 and NFKB2. Promoter activation in ARID1A-mutated GCs was associated with enhanced gene expression, increased BRD4 binding, and reduced HDAC1 and CTCF occupancy. Combined targeting of promoter activation and tumour inflammation via bromodomain and NFKB inhibitors confirmed therapeutic synergy specific to ARID1A-genomic status. CONCLUSION Our results suggest a therapeutic strategy for ARID1A-mutated GCs targeting both tumour-intrinsic (BRD4-assocatiated promoter activation) and extrinsic (NFKB immunomodulation) cancer phenotypes.

Abstract
We discuss the importance of the in vivo models in elucidating cancer biology, focusing on the patient-derived xenograft (PDX) models, which are classic and standard functional in vivo platforms for preclinical evaluation. We provide an overview of the most representative models, including cell-derived xenografts (CDX), tumor and metastatic cell-derived xenografts, and PDX models utilizing humanized mice (HM). The orthotopic models, which could reproduce the cancer environment and its progression, similar to human tumors, are particularly common. The standard procedures and rationales of gastric adenocarcinoma (GAC) orthotopic models are addressed. Despite the significant advantages of the PDX models, such as recapitulating key features of human tumors and enabling drug testing in the in vivo context, some challenges must be acknowledged, including loss of heterogeneity, selection bias, clonal evolution, stroma replacement, tumor micro-environment (TME) changes, host cell carryover and contaminations, human-to-host cell oncogenic transformation, human and host viral infections, as well as limitations for immunologic research. To compensate for these limitations, other mouse models, such as syngeneic and humanized mouse models, are currently utilized. Overall, the PDX models represent a powerful tool in cancer research, providing critical insights into tumor biology and potential therapeutic targets, but their limitations and challenges must be carefully considered for their effective use. Lastly, we present an intronic quantitative PCR (qPCR) method to authenticate, detect, and quantify human/murine cells in cell lines and PDX samples.

Abstract
Understanding tumor microenvironment (TME) reprogramming in gastric adenocarcinoma (GAC) progression may uncover novel therapeutic targets. Here, we performed single-cell profiling of precancerous lesions, localized and metastatic GACs, identifying alterations in TME cell states and compositions as GAC progresses. Abundant IgA+ plasma cells exist in the premalignant microenvironment, whereas immunosuppressive myeloid and stromal subsets dominate late-stage GACs. We identified six TME ecotypes (EC1-6). EC1 is exclusive to blood, while EC4, EC5, and EC2 are highly enriched in uninvolved tissues, premalignant lesions, and metastases, respectively. EC3 and EC6, two distinct ecotypes in primary GACs, associate with histopathological and genomic characteristics, and survival outcomes. Extensive stromal remodeling occurs in GAC progression. High SDC2 expression in cancer-associated fibroblasts (CAFs) is linked to aggressive phenotypes and poor survival, and SDC2 overexpression in CAFs contributes to tumor growth. Our study provides a high-resolution GAC TME atlas and underscores potential targets for further investigation.

Abstract
There is an urgent need for first-line treatment options for patients with human epidermal growth factor receptor 2 (HER2)-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction (mG/GEJ) adenocarcinoma. Claudin-18 isoform 2 (CLDN18.2) is expressed in normal gastric cells and maintained in malignant G/GEJ adenocarcinoma cells. GLOW (closed enrollment), a global, double-blind, phase 3 study, examined zolbetuximab, a monoclonal antibody that targets CLDN18.2, plus capecitabine and oxaliplatin (CAPOX) as first-line treatment for CLDN18.2-positive, HER2-negative, locally advanced unresectable or mG/GEJ adenocarcinoma. Patients (n = 507) were randomized 1:1 (block sizes of two) to zolbetuximab plus CAPOX or placebo plus CAPOX. GLOW met the primary endpoint of progression-free survival (median, 8.21 months versus 6.80 months with zolbetuximab versus placebo; hazard ratio (HR) = 0.687; 95% confidence interval (CI), 0.544-0.866; P = 0.0007) and key secondary endpoint of overall survival (median, 14.39 months versus 12.16 months; HR = 0.771; 95% CI, 0.615-0.965; P = 0.0118). Grade ≥3 treatment-emergent adverse events were similar with zolbetuximab (72.8%) and placebo (69.9%). Zolbetuximab plus CAPOX represents a potential new first-line therapy for patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or mG/GEJ adenocarcinoma.

Abstract
BACKGROUND Microscopically positive (R1) surgical margins after gastrectomy increase gastric cancer recurrence risk, but optimal management after R1 gastrectomy is controversial. We sought to identify the impact of R1 margins on recurrence patterns and survival in the era of preoperative therapy for gastric cancer. METHODS Patients who underwent gastrectomy for adenocarcinoma during 1998-2017 at a major cancer center were enrolled. Clinicopathologic factors associated with positive margins were examined, and incidence, sites, and timing of recurrence and survival outcomes were compared between patients with positive and negative margins. RESULTS Of 688 patients, 432 (63%) received preoperative therapy. Thirty-four patients (5%) had R1 margins. Compared with patients with negative margins, patients with R1 margins more frequently had aggressive clinicopathologic features, such as linitis plastica (odds ratio [OR] 7.79, p < 0.001) and failure to achieve cT downstaging with preoperative treatment (OR 5.20, p = 0.005). The 5 year overall survival (OS) rate was lower in patients with R1 margins (6% vs 60%; p < 0.001), and R1 margins independently predicted worse OS (hazard ratio 2.37, 95% CI 1.51-3.75, p < 0.001). Most patients with R1 margins (58%) experienced peritoneal recurrence, and locoregional recurrence was relatively rare in this group (14%). Median time to recurrence was 8.5 months for peritoneal dissemination and 15.7 months for locoregional recurrence. CONCLUSION R1 margins after gastrectomy were associated with aggressive tumor biology, high incidence of peritoneal recurrence after a short interval, and poor OS. In patients with R1 margins, re-resection to achieve microscopically negative margins has to be considered with caution.

Abstract
We sought to assess discordance of HER2 status in patients with HER2-amplified/expressing solid tumors who underwent reevaluation of HER2 status. Patients with metastatic solid tumors and HER2 expression by IHC or amplification by FISH/next-generation sequencing on local testing underwent central HER2 IHC/FISH testing with either archival or fresh biopsies and were evaluated for discordance in HER2 status. 70 patients (12 cancer types) underwent central HER2 reevaluation, including 57 (81.4%) with a new biopsy. In 30 patients with HER2 3+ on local IHC, 21 (70.0%) were 3+, 5 (16.7%) were 2+, 2 (6.7%) were 1+, and 2 (6.7%) had 0 HER2 expression on central IHC. In 15 patients whose cancers were 2+ on local IHC, 2 (13.3%) were 3+, 5 (33.3%) were 2+, 7 (46.7%) were 1+, and 1 (6.7%) had 0 HER2 expression on central IHC. HER2 discordance was seen in 16 of 52 (30.8%) of patients with HER2 overexpression/amplification who underwent a new image-guided biopsy. Discordance was observed in 10 (33.3%) of 30 patients who received intervening HER2-targeted therapy and in 6 (23.8%) of 22 patients who did not. In the 8 patients who had central HER2 assessment from the same archival block used for local testing, none were discordant. Discordance of HER2 status is common in patients with tumors previously identified as HER2-expressing, especially in patients with HER2 2+ tumors. Repeat biomarker evaluation may have value when considering HER2-targeted therapies.

Abstract
Gastric adenocarcinoma, even when diagnosed at an early (localized) disease stage, poses a major health-care burden with cure rates that remain unsatisfactorily low, particularly in Western countries. This lack of progress reflects, among other aspects, the impracticality of early diagnosis, considerable variations in therapeutic approaches that is partly based on regional preferences, and the ingrained heterogeneity of gastric adenocarcinoma cells and their associated tumour microenvironment (TME). Clinical trials have long applied empirical interventions with the assumption that all early stage gastric adenocarcinomas are alike. Despite certain successes, the shortcomings of these approaches can potentially be overcome by targeting the specific molecular subsets of gastric adenocarcinomas identified by genomic and/or multi-omics analyses, including microsatellite instability-high, Epstein-Barr virus-induced, DNA damage repair-deficient, HER2-positive and PD-L1-high subtypes. Future approaches, including the availability of sophisticated vaccines, novel antibody technologies, agents targeting TME components (including fibroblasts, macrophages, cytokines or chemokines, and T cells) and novel immune checkpoint inhibitors, supported by improved tissue-based and blood-based diagnostic assays, seem promising. In this Review, we highlight current knowledge of the molecular and cellular biology of gastric adenocarcinomas, summarize the current approaches to clinical management of the disease, and consider the role of novel management and/or treatment strategies.

Abstract
Advanced gastric adenocarcinoma (GAC) often leads to peritoneal carcinomatosis (PC) and is associated with very poor outcome. Here we report the comprehensive proteogenomic study of ascites derived cells from a prospective GAC cohort (n = 26 patients with peritoneal carcinomatosis, PC). A total of 16,449 proteins were detected from whole cell extracts (TCEs). Unsupervised hierarchical clustering resulted in three distinct groups that reflected extent of enrichment in tumor cells. Integrated analysis revealed enriched biological pathways and notably, some druggable targets (cancer-testis antigens, kinases, and receptors) that could be exploited to develop effective therapies and/or tumor stratifications. Systematic comparison of expression levels of proteins and mRNAs revealed special expression patterns of key therapeutics target notably high mRNA and low protein expression of HAVCR2 (TIM-3), and low mRNA but high protein expression of cancer-testis antigens CTAGE1 and CTNNA2. These results inform strategies to target GAC vulnerabilities.

Abstract
Tumor-infiltrating T cells offer a promising avenue for cancer treatment, yet their states remain to be fully characterized. Here we present a single-cell atlas of T cells from 308,048 transcriptomes across 16 cancer types, uncovering previously undescribed T cell states and heterogeneous subpopulations of follicular helper, regulatory and proliferative T cells. We identified a unique stress response state, TSTR, characterized by heat shock gene expression. TSTR cells are detectable in situ in the tumor microenvironment across various cancer types, mostly within lymphocyte aggregates or potential tertiary lymphoid structures in tumor beds or surrounding tumor edges. T cell states/compositions correlated with genomic, pathological and clinical features in 375 patients from 23 cohorts, including 171 patients who received immune checkpoint blockade therapy. We also found significantly upregulated heat shock gene expression in intratumoral CD4/CD8+ cells following immune checkpoint blockade treatment, particularly in nonresponsive tumors, suggesting a potential role of TSTR cells in immunotherapy resistance. Our well-annotated T cell reference maps, web portal and automatic alignment/annotation tool could provide valuable resources for T cell therapy optimization and biomarker discovery.

Abstract
BACKGROUND Zolbetuximab, a monoclonal antibody targeting claudin-18 isoform 2 (CLDN18.2), has shown efficacy in patients with CLDN18.2-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. We report the results of the SPOTLIGHT trial, which investigated the efficacy and safety of first-line zolbetuximab plus mFOLFOX6 (modified folinic acid [or levofolinate], fluorouracil, and oxaliplatin regimen) versus placebo plus mFOLFOX6 in patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. METHODS SPOTLIGHT is a global, randomised, placebo-controlled, double-blind, phase 3 trial that enrolled patients from 215 centres in 20 countries. Eligible patients were aged 18 years or older with CLDN18.2-positive (defined as ≥75% of tumour cells showing moderate-to-strong membranous CLDN18 staining), HER2-negative (based on local or central evaluation), previously untreated, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma, with radiologically evaluable disease (measurable or non-measurable) according to Response Evaluation Criteria in Solid Tumors version 1.1; an Eastern Cooperative Oncology Group performance status score of 0 or 1; and adequate organ function. Patients were randomly assigned (1:1) via interactive response technology and stratified according to region, number of organs with metastases, and previous gastrectomy. Patients received zolbetuximab (800 mg/m2 loading dose followed by 600 mg/m2 every 3 weeks) plus mFOLFOX6 (every 2 weeks) or placebo plus mFOLFOX6. The primary endpoint was progression-free survival assessed by independent review committee in all randomly assigned patients. Safety was assessed in all treated patients. The study is registered with ClinicalTrials.gov, NCT03504397, and is closed to new participants. FINDINGS Between June 21, 2018, and April 1, 2022, 565 patients were randomly assigned to receive either zolbetuximab plus mFOLFOX6 (283 patients; the zolbetuximab group) or placebo plus mFOLFOX6 (282 patients; the placebo group). At least one dose of treatment was administered to 279 (99%) of 283 patients in the zolbetuximab group and 278 (99%) of 282 patients in the placebo group. In the zolbetuximab group, 176 (62%) patients were male and 107 (38%) were female. In the placebo group, 175 (62%) patients were male and 107 (38%) were female. The median follow-up duration for progression-free survival was 12·94 months in the zolbetuximab group versus 12·65 months in the placebo group. Zolbetuximab treatment showed a significant reduction in the risk of disease progression or death compared with placebo (hazard ratio [HR] 0·75, 95% CI 0·60-0·94; p=0·0066). The median progression-free survival was 10·61 months (95% CI 8·90-12·48) in the zolbetuximab group versus 8·67 months (8·21-10·28) in the placebo group. Zolbetuximab treatment also showed a significant reduction in the risk of death versus placebo (HR 0·75, 95% CI 0·60-0·94; p=0·0053). Treatment-emergent grade 3 or worse adverse events occurred in 242 (87%) of 279 patients in the zolbetuximab group versus 216 (78%) of 278 patients in the placebo group. The most common grade 3 or worse adverse events were nausea, vomiting, and decreased appetite. Treatment-related deaths occurred in five (2%) patients in the zolbetuximab group versus four (1%) patients in the placebo group. No new safety signals were identified. INTERPRETATION Targeting CLDN18.2 with zolbetuximab significantly prolonged progression-free survival and overall survival when combined with mFOLFOX6 versus placebo plus mFOLFOX6 in patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma. Zolbetuximab plus mFOLFOX6 might represent a new first-line treatment in these patients. FUNDING Astellas Pharma, Inc.

Abstract
Gastroesophageal cancers are a group of aggressive malignancies that are inherently heterogeneous with poor prognosis. Esophageal squamous cell carcinoma, esophageal adenocarcinoma, gastroesophageal junction adenocarcinoma, and gastric adenocarcinoma all have distinct underlying molecular biology, which can impact available targets and treatment response. Multimodality therapy is needed in the localized setting and treatment decisions require multidisciplinary discussions. Systemic therapies for treatment of advanced/metastatic disease should be biomarker-driven, when appropriate. Current FDA approved treatments include HER2-targeted therapy, immunotherapy, and chemotherapy. However, novel therapeutic targets are under development and future treatments will be personalized based on molecular profiling. Herein, we review the current treatment approaches and discuss promising advances in targeted therapies for gastroesophageal cancers.

Abstract
INTRODUCTION Esophageal cancers continue to confer a dismal prognosis. Targeted and immune therapies have skyrocketed in the world of cancer management. Unlike other solid tumors, esophageal squamous cell carcinoma (ESCC) has lacked effective targeted therapy. Promising outcomes with immune checkpoint inhibitors (ICIs) have recently changed ESCC management. AREAS COVERED Nivolumab has been granted several approvals to treat ESCC patients. Nivolumab is recommended as adjuvant therapy for localized ESCC patients following trimodality therapy who have residual cancer in the surgical specimen (lymph node(s) and or the primary). CheckMate-648 led to dual ICI therapy approval with nivolumab plus ipilimumab or nivolumab plus platinum with fluoropyrimidine as first line treatment for unresectable ESCC patients. ATTRACTION-3 resulted in nivolumab approval for second line therapy of unresectable ESCC patients who have not been exposed to ICI. Here we provide a review of nivolumab and how this relates to ESCC management. EXPERT OPINION Some ESCC patients will not experience a response to ICIs. Determining intrinsic and acquired resistance patterns are needed to further capitalize on ICI therapy for ESCC patients. PD-L1 expression has been explored as a potential biomarker. Data shows, however, PD-L1 positive tumor patients benefit but this assessment is not always needed.

Abstract
Abstract
Background: Approximately 25% of patients with esophageal adenocarcinoma achieve pathological complete response (pathCR) after chemoradiotherapy with following surgery (trimodality therapy). The prediction for pathCR would provide an important guidance for decision making regarding surgical strategy. Previous studies have used the logistic regression model to predict pathCR, however, few studies utilized the machine learning models. In this study, we aimed to establish a predictive model for pathCR using the machine learning models using clinical data in patients with GEJ cancer treated by trimodality therapy. Methods: 512 patients with localized esophageal and GEJ adenocarcinoma who received trimodality therapy in MD Anderson Cancer Center between 2002 to 2020 were included. We first performed survival analysis to confirm the survival benefit of pathCR. Then, several prediction models commonly used in machine learning, including logistic regression, LASSO, Random Forest, BART, and xgboost were used to predict pathCR. Each method was trained and validated using 10-fold cross-validation. Results: A total of 125 patients (24 %) achieved a path CR. Patients who achieved path CR had significantly longer overall survival (OS) and relapse free survival (RFS) than <pathCR 387 patients (76%) (median OS, 132 months vs 58 months, respectively, p < 0.002; median RFS, 63 months vs 27 months, respectively, p < 0.001). The logistic regression model indicated non-signet ring cell subtype, T1/T2 stage, negative biopsy after chemoradiation were independent predictive factors for pathCR. Finally, we created machine learning models and LASSO showing the highest predictive ability with AUC value of 0.644 among those models including conventional logistic regression model. The percent partial AUC at lower false positive rate of 0.25 was higher than that of the conventional logistic regression model (% pAUC, 23.7 vs 21.8, respectively) Conclusion: We established the clinical predictive model for pathCR in patients with GEJ cancer treated by trimodality therapy using machine learning method with acceptable predictive ability. Addition of molecular features might further refine the models.

Abstract
Abstract
Introduction: Gastric adenocarcinoma (GAC), a global health burden, lacks detail understanding of the evolution-driven cellular/molecular programs that lead to GAC tumorigenesis followed by progression/metastases. How the TME is orchestrated by precancerous lesions, primary GAC, and in metastatic niches, when well understood, may propel us into an entirely new dimension with the hopes of novel therapeutics. However, only a few studies have investigated the immune/stromal subtypes of GAC with the limitation of scope, cohort size, and/or depth or mainly focused on the primary GACs. Here, we present an atlas of transcriptionally diverse TME across the full continuum of GAC by including peripheral blood, normal gastric tissues, premalignant lesions, localized, and metastatic GACs.
Methods: We performed a comprehensive single-cell profiling of 68 specimens collected from 43 subjects including a total of 77,392 high-quality cells which revealed 62 unique cell states uncovering varying profiles. We defined alterations in TMEs that underscore initiation of tumorigenesis to eventual progression.
Results: We found a striking preponderance of B lineage cells, primarily the IgA+ plasma cells, in TMEs of the precancerous lesions, whereas 3 immunosuppressive myeloid subsets dominated in advanced GACs. Fractions of GZMK+ effector CD8 T cells and progenitor exhausted CD8 T cells gradually increased as GACs progressed to advanced stages. In addition, our analysis revealed extensive stromal remodeling along the GAC continuum, which may have contributed to enhanced angiogenesis and immune suppressive signaling. The observations in the primary tumors could be validated in an independent scRNA-seq dataset. Notably, we uncovered 3 unique TME interactomes and defined 6 cellular environtypes inhabited by 62 TME cell subsets giving GAC to a novel landscape not yet defined. The two distinct environtypes in GAC primaries are validated in three independent large-scale GAC cohorts, giving credence and definition to previously established histopathological variables, genomic/molecular subtypes and clinical outcomes. The analysis of tumor associated stromal cells discovered SDC2 as an
exploitable target to pursue. SDC2 was abundant in cancer associated fibroblasts (CAFs), and the abundance is validated in 3 independent single-cell GAC cohorts as well as at the protein level. SDC2 expression was significantly higher in advanced (vs. early) stages and diffuse (vs. intestinal) type of GAC, and SDC2 overexpression was associated with shorter survival in all 5 large-scale GAC cohorts. Lastly, we assessed the functional effects of SDC2 expression in CAFs on tumor growth in vivo in xenograft models and found SDC2 overexpression in CAFs contributes to tumor growth.
Conclusion: This study provides an atlas of GAC TMEs from tumorigenesis to advanced GAC that could be further developed for novel therapeutics but also serves as a community resource.

Abstract
Abstract
Gastric adenocarcinoma (GAC) is one of the most common malignancies worldwide and it is the fourth leading cause of cancer-related death. Peritoneal carcinomatosis (PC; malignant ascites or implants) in GAC patients is common and poses a challenge with short survival and lack of effective therapeutics. We and others have demonstrated that deregulation of the Hippo signaling pathway particularly with upregulation of its coactivators-YAP1 or TAZ drive cancer progression and metastases in gastroesophageal cancers suggesting YAP1 and TAZ are potential drug targets in solid tumors. However, discovery of effective drugs to target YAP1 or TAZ remains challenging due to the nuclear localization and lack of inhibitory pocket for YAP1 or TAZ. In this study, using scRNAseq and immunofluorescent staining, we observed that both YAP1, TAZ and their transcriptional factors-Tead1, Tead2, Tead3 and Tead4 are highly expressed in PC tumor cells and high expression of these proteins were associated with poorer prognosis. Further, we note that recently developed YAP or TAZ antisense oligonucleotides (ASO) can effectively and specifically suppress YAP or TAZ expression and transcription accompanied by decreased tumor cell invasion and tumor sphere formation. Further, we observed that YAP1 can interact with TAZ and both bind TEAD1,2,3 but not Tead4 transcriptional factors, while YAP1 ASO or TAZ ASO can decrease the interactions between YAP1 or TAZ with TEAD1,2,3 in GAC cells. Interestingly, inhibition of YAP1 or TAZ alone using the ASOs can complementarily increase the other at the protein and mRNA levels. Further, we revealed that YAP1 KO patient derived tumor cells (GA0518) are more sensitive to TAZ ASO than control cells and simultaneously inhibition of YAP1 and TAZ by ASOs reduces both YAP1and TAZ proteins and mRNA levels with significant decrease in cell proliferation and invasive capacity of YAP1 high tumor cells. Most importantly, co-targeting YAP and TAZ by the ASOs significantly attenuated progression and PC in the PDX model and sensitized to anti-PD1 immunotherapy in the KP-Luc syngeneic model. Taken together, our studies open a new avenue for developing novel therapeutic strategy by co-targeting both YAP1 and TAZ using the ASOs against GAC with PC.

Abstract
Cancers originating in the esophagus or esophagogastric junction constitute a major global health problem. Esophageal cancers are histologically classified as squamous cell carcinoma (SCC) or adenocarcinoma, which differ in their etiology, pathology, tumor location, therapeutics, and prognosis. In contrast to esophageal adenocarcinoma, which usually affects the lower esophagus, esophageal SCC is more likely to localize at or higher than the tracheal bifurcation. Systemic therapy can provide palliation, improved survival, and enhanced quality of life in patients with locally advanced or metastatic disease. The implementation of biomarker testing, especially analysis of HER2 status, microsatellite instability status, and the expression of programmed death-ligand 1, has had a significant impact on clinical practice and patient care. Targeted therapies including trastuzumab, nivolumab, ipilimumab, and pembrolizumab have produced encouraging results in clinical trials for the treatment of patients with locally advanced or metastatic disease. Palliative management, which may include systemic therapy, chemoradiation, and/or best supportive care, is recommended for all patients with unresectable or metastatic cancer. Multidisciplinary team management is essential for all patients with locally advanced esophageal or esophagogastric junction cancers. This selection from the NCCN Guidelines for Esophageal and Esophagogastric Junction Cancers focuses on the management of recurrent or metastatic disease.

Abstract
OBJECTIVE Many cancers engage embryonic genes for rapid growth and evading the immune system. SOX9 has been upregulated in many tumours, yet the role of SOX9 in mediating immunosuppressive tumour microenvironment is unclear. Here, we aim to dissect the role of SOX9-mediated cancer stemness attributes and immunosuppressive microenvironment in advanced gastric adenocarcinoma (GAC) for novel therapeutic discoveries. METHODS Bulk RNAseq/scRNA-seq, patient-derived cells/models and extensive functional studies were used to identify the expression and functions of SOX9 and its target genes in vitro and in vivo. Immune responses were studied in PBMCs or CD45+ immune cells cocultured with tumour cells with SOX9high or knockout and the KP-Luc2 syngeneic models were used for efficacy of combinations. RESULTS SOX9 is one of the most upregulated SOX genes in GAC and highly expressed in primary and metastatic tissues and associated with poor prognosis. Depletion of SOX9 in patient-derived GAC cells significantly decreased cancer stemness attributes, tumour formation and metastases and consistently increased CD8+ T cell responses when cocultured with PBMCs/CD45+ cells from GAC patients. RNA sequencing identified the leukaemia inhibitory factor (LIF) as the top secreted molecule regulated by SOX9 in tumour cells and was enriched in malignant ascites and mediated SOX9-induced M2 macrophage repolarisation and inhibited T cell function. CONCLUSION Epithelial SOX9 is critical in suppressing CD8+ T cell responses and modified macrophage function in GAC through the paracrine LIF factor. Cotargeting LIF/LIFR and CSF1R has great potential in targeting SOX9-mediated cancer stemness, T cell immunosuppression and metastases suggesting the novel combination therapy against advanced GAC.

Abstract
WHAT IS THIS SUMMARY ABOUT? This is a summary of the 1-year results of a clinical research study known as CheckMate 649 published in The Lancet in June 2021. The 2-year results on the participants' health and overall quality of life from the same study are in a second publication in Nature in March 2022. Until recently, chemotherapy was the only first treatment option for people with advanced or metastatic gastroesophageal adenocarcinoma who had not been treated before. Patients receiving chemotherapy lived on average for less than 1 year. Nivolumab is an immunotherapy that works by activating a person's immune system to fight back against cancer cells. The goal of CheckMate 649 was to find out if the combination of nivolumab and chemotherapy would help patients with advanced or metastatic gastroesophageal adenocarcinoma live longer and without their cancer getting worse. WHAT WERE THE RESULTS? Results from the final analysis are reported here. Of 1581 people who took part in the study, 789 received nivolumab and chemotherapy and 792 received chemotherapy. Researchers found that, on average, participants who received nivolumab and chemotherapy lived longer overall than those who received chemotherapy alone. The length of time participants lived without their cancer getting worse was also longer on average with nivolumab and chemotherapy than chemotherapy treatment alone. However, more participants in the nivolumab and chemotherapy group had side effects than those in the chemotherapy group. The three most common side effects in both types of treatment were nausea (urge to vomit), diarrhea and peripheral neuropathy. Participants who received nivolumab and chemotherapy had a lower risk of their cancer symptoms worsening and reported that they were 'less bothered' from side effects of treatment than those receiving chemotherapy alone. WHAT DO THE RESULTS MEAN? The nivolumab and chemotherapy combination is considered a new standard treatment option and is approved in several countries as a treatment for adults who have not been treated before for their advanced or metastatic gastroesophageal cancer based on results from CheckMate 649. Clinical Trial Registration: NCT02872116 (ClinicalTrials.gov).

Abstract
The CROSS trial group deserves enormous credit for completing a well-powered randomized trial that has established the CROSS strategy as a standard of care for patients with potentially resectable esophageal cancer. However, the 10-year results are rather disappointing with only 38% of all patients treated with the CROSS strategy cured compared with approximately 25% who had surgery alone. Another standard, perioperative chemotherapy has produced similar disappointing results as the CROSS strategy. Although many of us are consumed by the question as to which option is better for our patients, we conclude that both strategies produce only marginal benefits. We should have better treatment options. The timing may be opportune to reflect on how to develop novel and rational strategies rather than propagate the historical empiric approaches.

Abstract
Cancers derived from the gastrointestinal (GI) tract are often treated with radical surgery to achieve a cure. However, recent advances in the management of GI cancers involve the use of a combination of neoadjuvant radiation and chemotherapy followed by surgical intervention to achieve improved local control and cure. Interestingly, a small proportion of patients with highly sensitive tumors achieved a pathological complete response (pCR) (no residual tumor cells in the resected specimen) to neoadjuvant chemoradiation therapy (nCRT). The desire for organ preservation and avoidance of surgical morbidity brings the idea of a nonoperative management (NOM) strategy. Because of the different nature of tumor biology, GI cancers present diverse responses to nCRT, ranging from high sensitivity (anal cancer) to low sensitivity (gastric/esophageal cancer). There is an increasing attention to NOM of localized GI cancers; however, without the use of biomarkers/imaging parameters to select such patients, NOM will remain a challenge. Therefore, this review intends to summarize some of the recent updates from the aspect of current nCRT regimens, criteria for patient selection and active surveillance schedules. We also hope to review significant sequelae of radical surgery and the complications of nCRT to clarify the directions for optimization of nCRT and NOM for oncologic outcomes and quality of life.

Abstract
Purpose To establish a fast and accurate detection method for interspecies contaminations in the patient-derived xenograft (PDX) models and cell lines, and to elucidate possible mechanisms if interspecies oncogenic transformation is detected. Methods A fast and highly sensitive intronic qPCR method detecting Gapdh intronic genomic copies was developed to quantify if cells were human or murine or a mixture. By this method, we documented that murine stromal cells were abundant in the PDXs; we also authenticated our cell lines to be human or murine. Results In one mouse model, GA0825-PDX transformed murine stromal cells into a malignant tumorigenic murine P0825 cell line. We traced the timeline of this transformation and discovered three subpopulations descended from the same GA0825-PDX model: epithelium-like human H0825, fibroblast-like murine M0825, and main passaged murine P0825 displayed differences in tumorigenic capability in vivo. P0825 was the most aggressive and H0825 was weakly tumorigenic. Immunofluorescence (IF) staining revealed that P0825 cells highly expressed several oncogenic and cancer stem cell markers. Whole exosome sequencing (WES) analysis revealed that TP53 mutation in the human ascites IP116-generated GA0825-PDX may have played a role in the human-to-murine oncogenic transformation. Conclusion This intronic qPCR is able to quantify human/mouse genomic copies with high sensitivity and within a time frame of a few hours. We are the first to use intronic genomic qPCR for authentication and quantification of biosamples. Human ascites transformed murine stroma into malignancy in a PDX model.

Abstract
LBA292 Background: 1L treatment for pts with HER2−, mG/GEJ adenocarcinoma is typically chemotherapy and immunotherapy; an unmet need still exists. CLDN18.2 is expressed in normal gastric mucosa cells and retained in mG/GEJ tumor cells. In the FAST study, zolbetuximab, which targets CLDN18.2, prolonged survival of pts with LA unresectable or mG/GEJ adenocarcinoma when combined with chemotherapy. SPOTLIGHT (NCT03504397) is a phase 3 global, double-blind study comparing zolbetuximab + folinic acid, 5-FU, and oxaliplatin (mFOLFOX6) vs placebo + mFOLFOX6 as 1L treatment for pts with CLDN18.2+/ HER2−, LA unresectable or mG/GEJ adenocarcinoma. Methods: Previously untreated pts with CLDN18.2+ (moderate-to-strong membrane staining in ≥75% tumor cells by IHC)/HER2− LA unresectable or mG/GEJ adenocarcinoma were randomized 1:1 to zolbetuximab IV 800 mg/m2 (cycle [C] 1, day [D] 1) followed by 600 mg/m2 (C1D22, and every 3 weeks in later cycles) + mFOLFOX6 IV (D1, 15, 29) for four 42-day cycles vs placebo + mFOLFOX6; pts without PD continued for >4 cycles with zolbetuximab or placebo, + folinic acid and 5-FU at investigator’s discretion until PD or discontinuation criteria were met. The primary endpoint (EP) was PFS per RECIST v1.1 by IRC. Secondary EPs included OS, ORR, and safety. Differences in efficacy between treatment arms were tested by stratified log rank tests; OS was tested if PFS was significant. Results: Among 2735 pts screened, 565 pts were randomized 1:1 to zolbetuximab + mFOLFOX6 (N = 283) or placebo + mFOLFOX6 (N = 282). PFS was statistically significantly improved with zolbetuximab + mFOLFOX6 (median 10.61 vs 8.67 mo, HR 0.751, P=0.0066; Table). OS was also significantly improved (median 18.23 vs 15.54 mo, HR 0.750, P=0.0053, < 0.0135 as boundary; Table). ORR was similar between treatment arms. Most common TEAEs with zolbetuximab + mFOLFOX6 were nausea (82.4% vs 60.8% in zolbetuximab vs placebo arms), vomiting (67.4% vs 35.6%), and decreased appetite (47.0% vs 33.5%); the incidences of serious TEAEs were similar between both arms (44.8% vs 43.5%). Conclusions: Targeting CLDN18.2 with 1L zolbetuximab combined with mFOLFOX6 statistically significantly prolonged PFS and OS in pts with CLDN18.2+/ HER2−, LA unresectable or mG/GEJ adenocarcinoma. TEAEs were consistent with previous studies. Zolbetuximab + mFOLFOX6 may be a new option for these pts. Funding source: This study was funded by Astellas Pharma Inc.

Abstract
349 Background: ADP-A2M4CD8 is a specific peptide enhanced affinity receptor mixed CD4+ and CD8+ T-cell therapy targeting the cancer testis antigen MAGE-A4 and modified with addition of a CD8α co-receptor designed to provide additional functionality to CD4+ T-cells. ADP-A2M4CD8 has demonstrated a favorable benefit to risk profile in the Phase 1 SURPASS trial (NCT04044859) in HLA A*02–eligible patients (pts) with unresectable or metastatic tumors positive for MAGE-A4 (Hong DS, et al. E-poster 540P: ESMO 2021; Virtual). Here we report updated clinical outcomes in pts with esophageal, esophagogastric junction (EGJ), or gastric cancer. Methods: SURPASS is a first-in-human trial consisting of a modified 3+3 dose-escalation design and an expansion cohort. Autologous T-cells are obtained by leukapheresis, transduced with a self-inactivating lentiviral vector expressing the MAGE-A4-specific T-cell receptor and the CD8α co-receptor, and infused back to the pts as ADP-A2M4CD8 following lymphodepleting chemotherapy. Primary and secondary objectives are safety and anti-tumor activity, respectively. Results: As September 6, 2022, 13 pts (11 male, 2 female) with esophageal (3), EGJ (8), and gastric cancer (2) received ADP-A2M4CD8 (range: 1.02–9.9x109 transduced T-cells). All pts had adenocarcinoma, median age was 55 years (range: 31–71), median MAGE-A4 expression H-score was 245 (range: 160–300), and pts received median of 2 lines of prior therapy (range 1–5). Adverse events (AEs) were consistent with those typically associated with lymphodepleting chemotherapy, cellular therapy, and/or disease. One pt had a Grade 5 (fatal) AE of pancytopenia. Overall response rate per RECIST v1.1 by investigator review was 15% (2 partial response [PR]). Disease control rate was 77% (2 PR+8 stable disease). This trial is ongoing, and additional data will be presented. Conclusions: Results indicate an acceptable benefit to risk profile and encouraging anti-tumor activity of ADP-A2M4CD8. An additional treatment cohort has been included in the updated SURPASS trial protocol to evaluate ADP-A2M4CD8 combined with nivolumab. A Phase 2, open-label trial in advanced esophageal and EGJ cancers has been initiated (SURPASS-2; NCT04752358). Clinical trial information: NCT04044859 .

Abstract
291 Background: NIVO + chemo demonstrated superior overall survival (OS) and clinically meaningful progression-free survival (PFS) benefit vs chemo and an acceptable safety profile in previously untreated patients (pts) with advanced GC/GEJC/EAC, leading to approvals in multiple countries including the US. NIVO + chemo continued to demonstrate clinically meaningful improvement in efficacy after 2 years of follow-up. We present efficacy and safety analyses from NIVO + chemo vs chemo from the 3-year follow-up of CheckMate 649. Methods: Adults with previously untreated, unresectable advanced, or metastatic GC/GEJC/EAC were enrolled, regardless of programmed death ligand 1 (PD-L1) expression. Pts with known HER2-positive status were excluded. Randomized pts received NIVO (360 mg Q3W or 240 mg Q2W) + chemo (XELOX Q3W or FOLFOX Q2W), NIVO + ipilimumab, or chemo. Dual primary endpoints for NIVO + chemo vs chemo were OS and PFS by blinded independent central review (BICR) in pts with PD-L1 combined positive score (CPS) ≥ 5. Results: 581 pts were concurrently randomized to NIVO + chemo or chemo. With 36-month (mo) minimum follow-up, NIVO + chemo continued to demonstrate OS and PFS benefit vs chemo in pts with PD-L1 CPS ≥ 5 and all randomized pts. The objective response rate (ORR) per BICR in pts with PD-L1 CPS ≥ 5 who had measurable lesions at baseline was 60% (95% CI 55–65) with NIVO + chemo vs 45% (95% CI 40–50) with chemo; in all randomized pts, ORR per BICR was 58% (95% CI 54–62) with NIVO + chemo vs 46% (95% CI 42–50) with chemo. Responses were more durable with NIVO + chemo vs chemo in pts with PD-L1 CPS ≥ 5 (median [m] duration of response [mDOR] 9.6 mo [95% CI 8.2–12.4] vs 7.0 mo [95% CI 5.6–7.9], respectively) and in all randomized pts (mDOR 8.5 mo [95% CI 7.7–9.9] vs 6.9 mo [95% CI 5.8–7.2], respectively). OS benefit with NIVO + chemo was observed across most prespecified subgroups. No new safety signals were identified. A summary of treatment-related adverse events (TRAEs) is shown here. Conclusions: After 3 years of follow-up, NIVO + chemo continued to demonstrate clinically meaningful long-term survival benefit with an acceptable safety profile, further supporting its use as a standard 1L treatment in previously untreated pts with advanced GC/GEJC/EAC. Clinical trial information: NCT02872116 . [Table: see text]

Abstract
400 Background: The management of esophageal cancer (EC) and gastroesophageal junction (GEJ) adenocarcinoma has focused on perioperative approaches that aim to increase pathological complete response (pathCR) rates, decrease or delay metastases, improve resectability, and enhance overall survival. Atezolizumab is a humanized immunoglobulin (Ig) G1 monoclonal antibody that targets PD-L1 and inhibits the interaction between PD-L1 and its receptors, PD-1, and B7-1, both of which function as inhibitory receptors expressed on T-cells. Therapeutic binding of PD-L1 by atezolizumab has been shown to enhance the magnitude and quality of tumor-specific T-cell responses, resulting in improved anti-tumor activity. The use of immunotherapy in combination with chemotherapy in the perioperative setting may improve the response rate in patients with localized EC and GEJ adenocarcinoma. Methods: We conducted a phase I study evaluating the efficacy and safety of atezolizumab in combination with oxaliplatin and 5-fluorouracil (modified FOLFOX) therapy in the perioperative setting. Patients with T1N1 or T2-3 (any N) localized EC and GEJ type I or II adenocarcinoma were included. Treatment consisted of oxaliplatin (85 mg/m2 over 2 hours on days 1 and 15) and 5-fluorouracil (2.4g/m2 (over 48 hours) via infusion pump on days 1 and 15) followed by atezolizumab (840 mg via IV on days 1 and 15) of each 28-day cycle for a total of 6 doses followed by surgery and subsequently postoperative atezolizumab 1200 mg IV on Day 1 of each 21-day cycle for 8 more doses. Results: From April 2019 to November 2020, 20 patients were enrolled with a median age of 61 years old and baseline TNM staging: T2-3N0 (n=8), T3N1-N2 (n=10), and T3N3-NX (n=2). Eighteen patients underwent surgery; two patients (11%, 95% credible interval = 1-28%) achieved the primary efficacy objective (pathCR defined as pathological T0N0), and two additional patients (11%) had near complete pathCR with <1% viable tumor. Fifteen patients (83%) had R0 resection. Grade 4 treatment-related events occurred in 2 patients and grade 2 and 3 treatment related events occurred in 9 and 7 patients respectively. No treatment-related events leading to discontinuation of therapy or treatment-related deaths occurred. Forty-five percent of the patients died and 44% of patients had recurrence with a median disease-free survival of 29 months. Conclusions: Results indicate that atezolizumab in combination with oxaliplatin and 5-fluorouracil has an acceptable safety profile providing high tumor regression. This trial supports further research of atezolizumab for the treatment of patients with localized EC and GEJ in the perioperative setting. Clinical trial information: NCT03784326 .

Abstract
347 Background: Zanidatamab (zani) is an anti-HER2 bispecific antibody against ECD4 and ECD2 with demonstrated activity and tolerability in a range of HER2-expressing cancers. This Phase (Ph) 2 study (NCT03929666) evaluates zani in combination with chemotherapy (chemo) as first-line treatment for patients (pts) with advanced HER2-expressing mGEA. Methods: Eligible pts for this ongoing, open-label study had not received any prior systemic therapy for mGEA. Pts received zani + physician’s choice of multi-agent chemo (mFOLFOX6, CAPOX, or FP). Antidiarrheal prophylaxis for cycle 1 was added after the first 25 pts were treated. Following demonstration of tolerability of the regimens in an initial safety cohort, the primary study objective was to evaluate antitumor activity. Results: Pts were enrolled between Aug 29, 2019 and Feb 18, 2022 with a data cutoff of July 28, 2022 (N=46 pts; zani + mFOLFOX6 [24], zani + CAPOX [20], or zani + FP [2]). Median age was 58 yrs; 85% male; 42 pts (91%) had HER2+ tumors (IHC 3+ or 2+ with ISH-positivity) based on central testing. Median duration of follow-up among all 46 pts was 21.5 months (mo) and 20 pts (43%) remain on treatment. In 38 response-evaluable pts with HER2+ tumors, confirmed objective response rate (cORR) was 79% (95% CI: 63-90%) and disease control rate was 92% (95% CI: 79-98%); 3 pts achieved complete response. Median duration of response (DOR) was 20.4 mo (95% CI: 6.8-not estimable [NE]), with 57% (17/30) pts having an ongoing response at data cut-off (1 pt has ongoing response >29 months). In all 42 pts with HER2+ tumors, median progression-free survival (PFS) was 12.5 mo (95% CI: 7.1-NE) and median overall survival (OS) was not yet reached. Survival rate at 18 mo was estimated to be 87.3%. The most common (≥25% pts) treatment-related (zani and/or chemo) adverse events (TRAE) in all pts were diarrhea, nausea, peripheral sensory neuropathy, decreased appetite, fatigue, vomiting, and hypokalemia. Diarrhea was the most common Gr3+ TRAE, lasting a median (interquartile range) of 3 (2-5) days, with the majority of events occurring in cycle 1; incidence of all Gr3+ events was 56% in 25 pts who did not receive prophylaxis and 14% in 21 pts who did. There were no treatment-related deaths. Conclusions: In pts with HER2+ mGEA, zani + chemo is a highly active treatment regimen with a manageable safety profile. This maturing data set demonstrates durable disease control with encouraging cORR, DOR, PFS and OS results. A global Ph 3 study (HERIZON-GEA-01; NCT05152147) evaluating zani in combination with physician’s choice of standard chemo with or without the PD-1 inhibitor, tislelizumab, for first-line treatment of advanced HER2+ mGEA is currently enrolling.

Abstract
290 Background: NIVO + chemo and NIVO + IPI demonstrated superior overall survival (OS) vs chemo in CheckMate 648 (NCT03143153), leading to approvals in the US, EU, Japan, and other countries. We report longer follow-up results. Methods: Adults with previously untreated, unresectable advanced, recurrent, or metastatic ESCC were randomized to NIVO (240 mg Q2W) + chemo (fluorouracil + cisplatin Q4W), NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W) or chemo. Primary endpoints were OS and progression-free survival (PFS) per blinded independent central review (BICR). Hierarchical testing was done first in patients (pts) with tumor cell programmed death ligand 1 (PD-L1) ≥ 1%, then in all randomized pts. Results: 970 pts were randomized to NIVO + chemo, NIVO + IPI, or chemo. With 29-mo minimum follow-up, NIVO + chemo and NIVO + IPI continued to show improvement in OS vs chemo, including higher 24-mo OS rates, in pts with tumor cell PD-L1 ≥ 1% and all randomized pts. Responses were more durable and a larger proportion of responders had a duration of response (DOR) ≥ 24 mo with NIVO + chemo and NIVO + IPI vs chemo in pts with tumor cell PD-L1 ≥ 1% (22%, 36%, 13%, respectively) and all randomized pts (21%, 29%, 13%). Additional efficacy data by PD-L1 status will be presented. Any-grade treatment-related adverse events (TRAEs) occurred in 96% (grade 3/4, 49%) of pts with NIVO + chemo, 80% (33%) with NIVO + IPI, and 90% (36%) with chemo. Any-grade TRAEs leading to discontinuation occurred in 35% of pts with NIVO + chemo, 19% with NIVO + IPI, and 21% with chemo. Treatment-related deaths occurred in 2% of pts in each arm. Conclusions: NIVO + chemo and NIVO + IPI continued to demonstrate clinically meaningful survival benefit vs chemo, durable objective responses, and acceptable safety profiles with longer follow-up. This further supports each regimen as a new 1L treatment option for advanced ESCC. Clinical trial information: NCT03143153 . [Table: see text]

Abstract
321 Background: OS is the gold standard efficacy measure in oncology; however, its need for prolonged follow-up motivates the establishment of SEs for earlier assessments of emerging treatments. We assessed DFS as a candidate SE for OS in early-stage EC/GEJC using data from Medicare beneficiaries with cancer in the SEER registry. Methods: Patients aged > 65 years in the US with resective surgery after a primary diagnosis of stage 2 or 3 EC/GEJC between 2009-2017 were analyzed (N=925; median follow-up 26.2 months). Surrogacy was assessed via both individual-level association of DFS to OS, and via the association between the treatment effects on DFS and OS. Strength of individual-level association was measured via Spearman’s rank correlation (ρ) non-parametrically and Kendall’s τ using copula functions. The strength of correlation between the treatment effects on DFS and OS—measured by the coefficient of determination (R2) and the surrogate threshold effect (STE), which is the minimum DFS benefit that would translate into statistically significant OS benefit—was derived from a regression model predicting OS hazard ratio (HR) from DFS HR. Patients were classified in clusters based on treatments they received and baseline characteristics (age, sex, index year, staging, and race/ethnicity). Propensity score matching addressed imbalances in baseline characteristics between the treatment and control groups in the constructed clusters. Predictive accuracy of the surrogacy equation was assessed internally via leave-one-out cross-validation and externally via predictions made for 26 RCTs of early-stage EC/GEJC. Results: Patients were mostly male (84%), non-Hispanic white (89.3%), with median age of 71.8 years and almost evenly distributed between cancer stages 2 (50.4%) and 3 (49.6%). Among patients receiving adjuvant (23.6%) or neoadjuvant (82.8%) treatment, most (81.7% of adjuvant and 92.0% of neoadjuvant therapies) received multi-agent chemotherapy. Spearman’s ρ was estimated to be 0.76 (95% CI: 0.70, 0.89) whereas estimates for Kendall’s τ ranged between 0.62 and 0.79. Estimated R2 for the correlation between treatment effects was 0.92 (95% CI: 0.56, 1.00) and estimated from the surrogacy equation log(HROS) = 0.02 + 1.09 × log(HRDFS) with a corresponding STE of 0.86. The 95% prediction intervals generated from this equation contained the raw OS HRs for 91% of the clusters in the internal validation, and 89% of the RCTs in the external validation. Conclusions: Correlations between DFS and OS, and between the treatment effects on these endpoints, were both moderate. The highly accurate surrogacy equation between the treatment effects can enable earlier assessments of OS benefit from the DFS benefit for early-stage EC/GEJC treatments in the real-world setting.

Abstract
369 Background: Validation of intermediate endpoints such as DFS as surrogates for overall survival (OS) in RCTs at individual-level remains as a challenge due to difficulty of collection of individual-level patient data. This study explores the individual-level correlation between DFS and OS indirectly using reconstructed Kaplan-Meier (KM) curves from the RCTs assessing therapies for (neo)adjuvant and perioperative treatment of EC/GEJC. Methods: An illness-death model previously validated in estimating individual-level association between DFS and OS for four correlation meta-analyses, two of which were published by the GASTRIC group, in early and late stage treatment of gastric cancer was employed. Reconstructed DFS and OS data from 25 RCTs published between 1994 - 2020 was pooled separately for each arm and each endpoint. Pooled data was analyzed to estimate the correlation between DFS and OS, as measured by Pearson’s r, Spearman’s rho, and Kendall’s tau. Predictive accuracy of the approach was evaluated by comparing its OS and restricted mean survival time (RMST) predictions to their counterparts obtained from the reported OS data from the RCTs. Sensitivity of correlation measures were assessed with respect to pre-specified variations in pre-recurrence death probability, post-recurrence mortality rate, and choice of the survival model used to extrapolate reported DFS curves from the RCTs. Results: Across all RCTs, the primary cancers covered were EC (n=13), EC/GEJC(n=9), GEJC (n=2) and GEJC/gastric cancer (n=1). According to the histology, 10 RCTs studied only squamous cell carcinoma (SCC) and 9 RCTs studied only adenocarcinoma (AC) of the disease, whereas the remaining 6 RCTs included varying mixtures of SCC and AC patients. The follow-up duration ranged between 27 and 72 months across RCTs. Comparator and intervention arms of the pooled data had 2499 and 2490 patients, respectively. Predicted Pearson’s r, Spearman’s rho, Kendall’s tau were 0.67, 0.79, and 0.70, respectively with negligibly narrow 95% CIs. Across both arms of the pooled data, on average, predicted OS curves laid within the 95% CIs of the pooled OS KM-curves 92% of the time. Average deviation between the RMSTs under the model-predicted OS curves and pooled OS KM curves was 2%. In sensitivity analyses, the ranges for r, r, and t were (0.56-0.88), (0.69-0.89), and (0.61-0.80), respectively. Conclusions: Results indicate moderate-to-strong correlation between DFS and OS in early-stage treatment of EC/GEJC providing supportive evidence for the validation of DFS as a surrogate for OS. Our approach mitigates the lack of patient level data in endpoint correlation assessment but may be prone to changes in the predicted value of pre-recurrence death probability.

Abstract
Gastric adenocarcinomas are a significant cause of cancer and cancer death, globally. The curative approach for those with diagnosed localized disease is with surgical resection and an adjunctive approach of perioperative chemotherapy, postoperative adjuvant therapy, or postoperative chemoradiation. Unfortunately, a universal standard approach is lacking for adjunctive therapy which in part has limited the progress achieved in this area. Metastatic disease is common in the Western world at diagnosis. Metastatic disease is treated palliatively with systemic therapy. Targeted therapy has stalled in approvals in gastric adenocarcinomas. Recently, we have seen the exploration of promising targets along with the addition of immune checkpoint inhibitors in select patients. Here, we review recent advances seen in gastric adenocarcinomas.

Abstract
Immune-stimulator antibody conjugates (ISAC) combining tumor-targeting monoclonal antibodies with immunostimulatory agents allow targeted delivery of immune activators into tumors. NJH395 is a novel, first-in-class ISAC comprising a Toll-like receptor 7 (TLR7) agonist conjugated to an anti-HER2 antibody via a noncleavable linker payload. Preclinical characterization showed ISAC-mediated activation of myeloid cells in the presence of antigen-expressing cancer cells, with antigen targeting and TLR7 agonism contributing to antitumor activity. Safety, efficacy, immunogenicity, pharmacokinetics, and pharmacodynamics were investigated in a phase I, multicenter, open-label study in patients with HER2+ non-breast advanced malignancies (NCT03696771). Data from 18 patients enrolled in single ascending dose escalation demonstrated delivery of the TLR7-agonist payload in HER2+ tumor cells and induction of type I IFN responses, which correlated with immune modulation in the tumor microenvironment. Cytokine release syndrome was a common, but manageable, drug-related adverse event. Antidrug antibodies and neuroinflammation at high doses represented significant clinical challenges. Data provide proof-of-mechanism and critical insights for novel immunotherapies.

Abstract
INTRODUCTION Gastroesophageal adenocarcinoma is relatively common in elderly patients as the incidence increases with age. However, the optimal treatment approach is not well established in this group of patients. The aim of this study is to review our experience for localized gastroesophageal adenocarcinoma in patients aged ≥80 years and to assess association between patient characteristics, clinical factors, and overall survival (OS) in order to optimize the therapeutic approaches for this population. METHODS Patients ≥80 years old treated for localized gastroesophageal adenocarcinoma were retrospectively analyzed. Survival curves were estimated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards regression models were applied to assess the association between patient characteristics and OS. Factors that were significant in the multivariate model were included in the final reduced model. RESULTS 127 patients ≥80 years old, were included in this study with median age of 83 years. The median follow-up time was 3.2 years, and median OS was 2.5 years (95% CI: 2.0-3.1 years). Independent prognostic factors for OS were Eastern Cooperative Oncology Group (ECOG) performance status (PS) (p = 0.003), baseline clinical stage (p = 0.01), and surgery (p = 0.001). ECOG PS, tumor location, baseline stage, tumor grade, and surgery were included in the final reduced model. CONCLUSION Surgical treatment can improve survival in elderly patients. Therapeutic decisions should be based on the patients' general condition rather that age alone.

Abstract
INTRODUCTION Gastroesophageal cancers (GEC) are frequently found at the advanced stage. GEC treatment advancements have been limited and prognosis, therefore, remains poor. Through numerous clinical trials, the addition of immune checkpoint inhibitors, including nivolumab, to conventional therapy has demonstrated a survival benefit. AREAS COVERED Here, we focus on the function of nivolumab in patients with advanced GECs. We discuss the most recent trials that led to nivolumab's incorporation into therapy and pathways forward. EXPERT OPINION Nivolumab in combination with chemotherapy appears well tolerated, with only a small number of patients reporting severe toxicity; therefore, it may be possible to add additional biological agents to improve outcomes. A number of 'nivolumab plus other agents' is currently being investigated, and we anticipate continued advancement in GEC management in the coming years.
