An increase in the frequency of CD8 + T-cells and a decreased frequency of tissue-resident memory 1 (Trm-1) and regulatory T (Treg) cells are associated with a favorable response to neoadjuvant therapy. Spatiotemporal multiomics analysis highlighted tissue-resident macrophages as potential predictive biomarkers and warrants further verification.

Patients were divided into two groups: the observation group (sintilimab + apatinib + albumin-bound paclitaxel, n = 42) and the control group (apatinib + albumin-bound paclitaxel, n = 42). The combination of an anti-PD-1 monoclonal antibody with chemotherapy and anti-angiogenic agents demonstrated preliminary efficacy and favorable safety in second-line gastric cancer patients. This study, using real-world data, validates the clinical benefit of this triple regimen, addresses the evidence gap in second-line treatment options, provides new insights for personalized combination strategies in advanced gastric cancer, and holds significant value for guiding clinical practice.

Future priorities: accelerate late-phase trials for promising regimens, reduce global disparities via regional consortia, integrate precision biomarkers for patient stratification, and translate TME insights into trials. This analysis highlights the need to shift from conventional chemotherapy optimization to precision-driven, globally equitable strategies to improve outcomes for high-risk osteosarcoma patients.

Initial treatment with camrelizumab plus CAPOX followed by camrelizumab based maintenance was associated with longer overall survival than CAPOX alone in human epidermal growth factor receptor 2 (HER2) negative, unresectable, locally advanced or metastatic gastric or gastro-oesophageal junction adenocarcinoma. Exploratory comparisons between the two camrelizumab based regimens showed no additional survival benefit, with higher rates of treatment related adverse events of grade ≥3 and treatment discontinuations when apatinib was added during maintenance.

We hypothesize that the combination of these four therapeutic strategies could significantly enhance treatment efficacy in HER2-positive gastric cancer, particularly in combined positive score (CPS) PD-L1-negative patients. This study was registered at ClinicalTrials.gov (Identifier: NCT06385873).

Furthermore, through computer-simulated clinical trials, we find that reducing the dose of apatinib in combination therapy to 125 mg can still achieve therapeutic effects comparable to the original dose. These findings provide valuable insights for future drug development and clinical trial design.
