The Foundational Role of IHC in Gastric Cancer Diagnostics
Immunohistochemistry (IHC) is indispensable in gastric cancer management, offering precise molecular profiling crucial for personalized treatment. It bridges classic pathology with modern molecular biology by visualizing protein expression directly within the tumor's architectural context. This allows for detailed classification, guiding targeted therapies like immune checkpoint inhibitors or anti-HER2 treatments.

Gastric Cancer Heterogeneity and Diagnostic Challenges
Gastric cancer is a highly heterogeneous disease, both morphologically and molecularly, influenced by genetic and environmental factors. This complexity makes accurate diagnosis challenging, especially for poorly differentiated tumors or metastatic lesions. IHC plays a critical role in differentiating tumor types and identifying specific molecular subtypes, which is essential for guiding therapeutic decisions and predicting patient prognosis.
Key Finding: HER2 Overexpression Rate
0 of esophagogastric junction cancers show HER2 overexpression, a critical biomarker for targeted therapy.Precision Biomarkers for Personalized Treatment
Key IHC biomarkers such as HER2, PD-L1, MMR, and emerging markers like CLDN18.2 are crucial for guiding targeted therapies in gastric cancer. These markers allow for a direct correlation between tissue morphology and protein expression, enabling pathologists to select patients for specific treatments like Trastuzumab or immune checkpoint inhibitors.

Innovations in IHC: Enhancing Sensitivity and Specificity
Advances in IHC techniques, such as Tyramide Signal Amplification (TSA), hybridization chain reaction (HCR), multiplex IHC (mIHC), and the integration of AI-assisted digital pathology, are overcoming previous limitations. These innovations improve sensitivity for low-abundance targets, allow simultaneous visualization of multiple markers, and enhance diagnostic accuracy and reproducibility, crucial for precision oncology.
Case Study: AI-Assisted PD-L1 Scoring in Gastric Cancer
Challenge: Manual scoring of PD-L1 Combined Positive Score (CPS) in gastric cancer is complex, laborious, and prone to high inter-observer variability, directly impacting patient eligibility for immunotherapy.
AI Solution: Implementation of AI algorithms, specifically convolutional neural networks (CNNs) and RepVGG, for automated PD-L1 CPS scoring. These systems are trained on large datasets to accurately identify and quantify PD-L1 positive tumor cells, lymphocytes, and macrophages, while excluding artifacts and non-viable areas.
Impact: AI systems demonstrated a Kappa coefficient of 0.78 agreement with expert consensus, providing crucial standardization for immunotherapy decisions. For HER2 scoring, AI achieved 94.0% accuracy, helping to resolve ambiguities in IHC 2+ cases. This significantly reduces turnaround time, improves reproducibility, and ensures more consistent patient selection for life-saving treatments, directly addressing the clinical need for precision in immunotherapy.
